### Patient Information  
**Name:** David Kim**Sex/Age:** Male / 47y/o  

### Specimen Identification  
- **Accession #:** LP‑47321‑BXC  
- **Procedure Date:** [date withheld]  CT‑Guided Percutaneous Core Needle Biopsy  
- **Anatomic Site:** Left Upper Lobe (segment S³⁄⁴), Lung Parenchymal Mass, C34.2  

### Type of Specimen  
Core needle biopsy specimens obtained under computed tomography guidance; 5 dedicated cores placed in formalin.

---  

## Gross Description  

| Item | Quantity | Dimensions (mm) | Appearance |
|------|----------|-----------------|------------|
| Core #1 | 1 | 18 × 2 × 2 | Tan–white, firm, focally hemorrhagic |
| Core #2 | 1 | 16 × 2 × 2 | Tan–white, gritty |
| Core #3 | 1 | 15 × 2 × 2 | Grayish-pink, soft |
| Core #4 | 1 | 13 × 2 × 2 | White, rubbery |
| Core #5 | 1 | 12 × 2 × 2 | Pink-tan, friable |

All cores were inked, bisected longitudinally, submitted entirely in cassettes labeled “LP‑47321‑BX”. Tissue fixed in neutral buffered formalin for ≥24hours before processing.

---  

## Microscopic Examination  

*Histopathology:* Sections reveal sheets and nests of markedly atypical malignant cells set against a background of desmoplastic stroma and foci of geographic necrosis. Tumor cells display moderate-to-large eosinophilic cytoplasm, vesicular nuclei with coarse clumped chromatin, conspicuous nucleoli (≥2×size of adjacent lymphocyte nucleus), and frequent abnormal mitoses (>20/10 HPF). Occasional rosette-like arrangements and scant intracytoplasmic granules suggest neuroendocrine differentiation.

*Architectural pattern*: Predominantly solid growth with occasional trabecular formation; absence of glandular/tubular structures excludes adenocarcinoma component. No keratin pearls or squamous maturation observed.

*Margin evaluation*: All margins represented by peripheral fragments of normal alveolar parenchyma; unable to assess true radial margin due to limited sampling inherent to core biopsies.

---  

## Immunohistochemistry & Ancillary Tests  

| Marker | Result | Interpretation |
|--------|--------|----------------|
| Pan‑Cytokeratin (AE1/AE3) | Diffuse strong membranous staining | Confirms epithelial origin |
| Neuroendocrine Markers:<br>- Synaptophysin | Focal (+) in ≈30% of tumor cells | Supports neuroendocrine phenotype |
| - Chromogranin A | Weak focal (+) | Consistent with neuroendocrine differentiation |
| - CD56 (NCAM) | Positive (moderate) | Reinforces neuroendocrine profile |
| TTF‑1 | Negative | Typical for large‑cell histotype lacking adenocarcinoma lineage |
| Napsin A | Negative | Excludes conventional adenocarcinoma |
| p40/p63 | Negative | Rules out squamous differentiation |
| Ki‑67 (MIB‑1) | Approximately 55% labeling index (high) | High proliferative activity |
| PD‑L1 (22C3 pharmDx) | Tumor Proportion Score = 10% (TPS) | Low-level expression |

*Molecular Testing:* None performed on this specimen; subsequent next‑generation sequencing ordered on parallel material (see separate record).

---  

## Diagnostic Summary  

**Primary Diagnosis:**   
Large Cell Carcinoma of the Lung, left upper lobe, exhibiting neuroendocrine features, WHO grade III (high proliferative rate).  

**Additional Comments:**  
- The presence of focal neuroendocrine marker positivity indicates divergent differentiation but does not meet criteria for definitive small‑cell carcinoma.  
- Ki‑67 index of 55% underscores aggressive biology; however, therapeutic decisions should integrate staging data and molecular profile (KRAS, STK11, etc.) obtained subsequently.  
- PD‑L1 expression measured at 10% (22C3) suggests modest checkpoint inhibitor targetability; interpretation should consider overall tumor microenvironment and forthcoming systemic options.

### Patient Information  
**Name:** David Kim**Sex/Age:** Male / 47y/o  

### Specimen Details  
| Item | Description |
|------|-------------|
| **Specimen ID** | LR-LU‑00123 (Left Upper Lobe Core Biopsy) |
| **Date of Collection** | [date omitted] |
| **Source** | Computed tomography–guided core needle biopsy  left upper lobe pulmonary mass (≈5cm) |
| **Histology (from accompanying H&E)** | Large‑cell carcinoma with focal neuroendocrine differentiation |

### Test Performed  
*Targeted DNA & RNA hybrid capture panel covering >300 cancer‐relevant genes (including SNVs, indels, copy number alterations, splice site changes, selected gene fusions).*  

Sequencing platform: Illumina NovaSeq 6000  
Average depth of coverage (tumor): ~850×  
Tumor cellularity estimated at 65%.

### Detected Genomic Alterations  

| Gene | Variant | Allele Frequency* | Interpretation |
|------|---------|-------------------|---------------|
| **KRAS** | c.35G>T (p.Gly12Val) | 38% | Activating missense mutation typical of driver oncogene in NSCLC. |
| **STK11** | Whole‑gene deletion (loss) inferred from copy‑number analysis | NA | Tumor suppressor loss associated with aggressive phenotype and reduced response to immune checkpoint blockade. |
| **KEAP1** | c.1796_1800del (p.Leu599Serfs*13) | 32% | Loss‑of‑function frameshift leading to NRF2 pathway activation; linked to resistance to oxidative stress and potentially poorer outcomes. |
| **TP53** | c.658A>G (p.Tyr220Cys) | 41% | Missense mutation affecting DNA‑binding domain; classic tumor‑suppressor alteration conferring genomic instability. |
| **MET** | Exon14 skipping transcript detected (low‑level)  junction reads supporting Δex14 | Approx. 5% (estimated from RNA read count) | In-frame splicing variant resulting in impaired degradation of MET protein; low allelic burden suggests subclonal population. |
| **ALK** | Rearrangement  Not detected (RNA fusion assay negative) |  | No actionable ALK fusion identified. |
| **ROS1** | Rearrangement  Not detected (RNA fusion assay negative) |  | No actionable ROS1 fusion identified. |

\*Allele frequency reflects proportion of mutant reads relative to total reads at the locus (DNA‑based unless otherwise noted).

### Additional Technical Notes  

- **Quality Metrics:** All target regions achieved ≥100× coverage; mean uniformity = 96%. No evidence of sample contamination.  
- **Microsatellite Instability (MSI):** Stable (no MSI‑high signature observed).  
- **Tumor Mutational Burden (TMB):** Estimated 7 mut/Mb (intermediate range for NSCLC).  

### Interpretative Summary  

The comprehensive profiling of the left upper lobe large‑cell carcinoma reveals:

1. An *activating KRAS G12V* point mutation, establishing KRAS as the principal oncogenic driver. This alteration is known to confer sensitivity to emerging KRAS^G12C inhibitors (e.g., adagrasib, sotorasib) when the cysteine substitution is present; however, G12V does not fall under current FDA‑approved KRAS inhibitor indications, though investigational agents targeting non‑cysteine KRAS mutants exist.

2. Co‑occurrence of **STK11 loss**, **KEAP1 mutation**, and **TP53 Y220C**—a constellation frequently seen in “KP” (KRAS + TP53) or “KL” (KRAS + LKB1/STK11) molecular subsets of lung adenocarcinoma. The presence of STK11 loss and KEAP1 mutation has been correlated with diminished responsiveness to anti‑PD‑(L)1 immunotherapy and more aggressive clinical behavior.

3. Low‑frequency **MET exon14 skipping** transcripts suggest a minor subclone harboring this alteration. While MET exon14 skipping is an established actionable target (responsive to MET TKIs such as crizo, tepotinib, savolitinib), the subclonal nature (<10%) raises uncertainty regarding therapeutic benefit.

4. Absence of **ALK** or **ROS1** rearrangements eliminates eligibility for approved ALK/ROS1 tyrosine kinase inhibitors.

Overall, the molecular landscape underscores KRAS-driven oncogenesis accompanied by additional tumor‑suppressor losses that may influence prognosis and selection of systemic therapy strategies.

### Limitations  

- The detection limit for subclonal alterations approximates 5%; very low‑abundance events below this threshold could remain undetected.  
- Formal validation of MET exon14 skipping via orthogonal methods (e.g., RT‑PCR) was not performed due to limited tissue availability.

### EXAMINATION
**Modality:** Integrated whole‑body **^18F‑FDG Positron Emission Tomography / Computed Tomography (PET/CT)**   
**Protocol Summary:** Patient fasted ≥6h, blood glucose measured at 92mg/dL before intravenous administration of 370MBq (≈10mCi) ^18F‑FDG. Uptake phase lasted ≈60min. Low‑dose non‑contrast CT obtained for attenuation correction and anatomical localization, followed by standard‐duration helical PET acquisition from skull base through mid‑thigh. Images reconstructed with iterative algorithm; axial slice thickness 3–5mm.

**Comparison:** None  this is the baseline pre‑therapy study following recent tissue diagnosis.

## FINDINGS  

| Region | Observation |
|--------|-------------|
| **Thorax  Lungs** |  **Left Upper Lobe (segment S¹⁺²):** 5.0×4.3×4.0cm irregular soft‑tissue mass centered in the posterior segment. On PET, markedly increased FDG accumulation with **maximum standardized uptake value (SUVₘₐₓ) = 12.0**, heterogeneous internal metabolism, peripheral rim of slightly lower activity likely reflecting necrosis.<br>• **Ipsilateral (left) hilar region (station10L):** Single enlarged lymph node measuring 1.4cm short axis, demonstrating focal FDG avidity (**SUVₘₐₓ  8.5**) concordant with metabolically active nodal disease.<br>• **Contralateral lung fields:** No discrete pulmonary nodules or areas of abnormally increased FDG uptake.<br>• **Pleura:** No pleural thickening or effusion. |
| **Mediastinum & Central Structures** | No additional FDG‑avid mediastinal lymph nodes beyond the aforementioned hilar node. Cardiac silhouette unremarkable. |
| **Upper Abdomen (liver, adrenal glands, pancreas, spleen)** | Normal physiologic hepatic uptake; no focal hypermetabolic foci in liver, bilateral adrenals, pancreas, or spleen. |
| **Lower Abdomen/Pelvis** | Physiologic bowel activity without focal abnormalities. No osseous lesions demonstrably hypermetabolic. |
| **Bone Survey** | No focal skeletal uptake above background suggesting metastatic disease. |
| **Soft Tissue** | Unremarkable musculature and skin. |

*Overall image quality satisfactory.*

## IMPRESSION  

1. **Baseline metabolic characterization** of histologically proven left upper‑lobe large‑cell carcinoma with prominent FDG uptake (**SUVₘₐₓ=12**), confirming high glycolytic activity typical of aggressive NSCLC.  
2. **Single ipsilateral hilar lymph node** (station10L) demonstrates significant FDG avidity (**SUVₘₐₓ8.5**), supporting clinical N1 classification.  
3. **Absence of FDG‑avid disease** elsewhere (contralateral lung, mediastinum, supraclavicular regions, abdomen, pelvis, skeleton)  no detectable distant metastasis (cM0).  
4. Radiographic staging aligns with **clinical stage IIIA (cT2bN1M0)** per AJCC 8ᵗʰ edition.  

These findings provide essential baseline data for forthcoming multimodality therapy planning (induction chemoradiation followed by surgery). Continued close imaging surveillance is advised post‑treatment to assess response.

### Patient Information  
**Name:** David Kim**Age:** 47**Sex:** Male  

---  

## Chief Complaint  
Evaluation and management plan for newly diagnosed left‐upper‑lobe non–small cell lung cancer (NSCLC), stage IIIA (cT2bN1M0), histologically classified as large‑cell carcinoma with neuroendocrine features.

---  

## History of Present Illness  
David Kim is a previously healthy 47‑year‑old man who presented three months ago following an incidentally detected pulmonary opacity on a screening computed tomography (CT) scan obtained for occupational health surveillance. He denies cough, hemoptysis, dyspnea, wheezing, fever, weight loss, night sweats, or chest pain. His performance status is estimated at Eastern Cooperative Oncology Group (ECOG) 0.

Bronchoscopy with CT‑guided core needle biopsy of the left upper lobe (segment1) yielded a poorly differentiated large‑cell carcinoma exhibiting focal neuroendocrine differentiation. Immunohistochemistry demonstrated synaptophysin positivity in scattered cells. The proliferative index (Ki‑67) was elevated at 55%; programmed death‑ligand 1 (PD‑L1) expression measured by 22C3 assay was 10%.

Comprehensive next‑generation sequencing (NGS) performed on the same tissue sample identified:

| Gene | Alteration |
|------|------------|
| **KRAS** | G12V (activating) |
| **STK11** | Loss-of-function |
| **KEAP1** | Missense mutation |
| **TP53** | Y220C missense |
| **MET** | Low‑level exon14 skipping |

No ALK or ROS1 rearrangements were detected. Fluorescence in situ hybridization (FISH) for EGFR amplification was negative.

Staging work‑up consisted of contrast‑enhanced chest CT demonstrating a 5.0×4.5cm spiculated mass involving the posterior segment of the left upper lobe with associated atelectasis, and a solitary enlarged ipsilateral hilar lymph node measuring 1.8cm. No additional intrathoracic adenopathy was visualized. Whole‑body ^18F‑FDG PET/CT disclosed intense metabolic activity confined to the primary lesion (SUV_max=12) and the involved hilar node (SUV_max8). Brain MRI was unremarkable. Overall staging is cT2bN1M0  stage III​A (AJCC 8th edition).

He has never smoked cigarettes (never‑smoker), works as a software engineer, lives with his spouse, and drinks socially (<2drinks/week). There is no personal or familial history of malignancy aside from a paternal uncle with colorectal cancer diagnosed at age68.

## Radiology Summary  

**Contrast Chest CT (Axial):** Left upper lobe posterior segment harbors a 5.0×4.5cm irregular soft‑tissue mass causing adjacent bronchial narrowing; internal heterogeneity suggests necrosis. One ipsilateral hilar LN measures 1.8cm short axis, mildly hyperattenuating. No contralateral hilar or mediastinal nodes >1cm. No pleural effusion or chest wall invasion.  

**^18F‑FDG PET/CT:** Intense FDG avidity localized to the aforementioned primary lesion (SUV_max=12) and the left hilar node (SUV_max8). No extrathoracic foci of increased metabolism.  

Interpretation aligns with clinically staged cT2bN1M0 disease.

---  

## Assessment  

1. **StageIIIA (cT2bN1M0) left‑sided large‑cell carcinoma with neuroendocrine features**, harboring KRAS G12V, STK11 loss, KEAP1, TP53 mutations, low‑level MET exon14 skipping, PD‑L1 ≈10%.  
   - High‑risk biologic profile (concurrent KRAS/STK11/KEAP1 alterations) predicts modest response to immunotherapy alone.  
   - Molecular landscape does not presently support FDA‑approved targeted agents beyond investigational KRAS inhibitors.  

2. **Overall Health Status:** Excellent functional reserve (ECOG0), adequate organ function, suitable candidate for multimodality curative intent therapy.

---  

## Plan / Recommendations  

After thorough interdisciplinary discussion among Thoracic Surgery, Radiation Oncology, Pulmonary Medicine, and Medical Oncology, consensus recommends **induction concurrent chemoradiation followed by surgical resection**—the standard approach for fit patients with potentially resectable stageIIIA NSCLC when mediastinal clearance cannot be guaranteed preoperatively.

1. **Radiation Oncology Referral**
   - Initiate simulation for definitive thoracic irradiation targeting the primary tumor and involved hilar station with elective coverage of stations5–7. Planned dose: **60Gy in 30 fractions** (2Gy/fraction).  
   - Discuss volumetric modulated arc therapy (VMAT) vs intensity‑modulated RT (IMRT) to minimize esophageal and heart exposure.

2. **Medical Oncology  Chemotherapy Regimen**
   - Concurrent systemic therapy: **carbo AUC2 IV weekly** + **Taxol 45mg/m² IV weekly** administered on days1,8,15,22,29 of radiation course. This regimen balances efficacy with tolerability in combined modality settings.  
   - Pre‑medication with dexamethasone, diphenhydramine, and famotidine per institutional protocol to mitigate hypersensitivity reactions.  
   - Baseline labs (CBC, CMP) repeated before each cycle; hold chemotherapy for ANC<1500/mm³ or platelets<100000/mm³.

3. **Supportive Care Measures**
   - Prophylactic antiemetics (ondansetron PRN) and stool softeners (docusate) to reduce GI toxicity.  
   - Nutritional counseling; consider oral cryotherapy during radiation sessions to lessen esophagitis risk.  
   - Encourage continued aerobic exercise; monitor weight and muscle mass.

4. **Pre‑operative Evaluation**
   - Upon completion of chemoradiation (approximately 6‑8weeks), repeat staging CT/PET to assess radiographic response.  
   - Reassess cardiopulmonary fitness (PFTs, VO₂ max) to confirm operative candidacy.  
   - Schedule video‑assisted thoracoscopic surgery (VATS) left upper lobectomy with systematic mediastinal lymphadenectomy (stations5,6,7,10L) contingent upon favorable restaging.

5. **Discussion of Alternatives & Risks**
   - Reviewed alternative approaches including definitive chemoradiation without surgery versus upfront surgery followed by adjuvant therapy. Emphasized higher local control rates and potential survival benefit with trimodal strategy in appropriately selected patients.  
   - Informed consent regarding acute toxicities (esophagitis, pneumonitis, myelosuppression) and late sequelae (fibrosis, reduced pulmonary reserve).  

6. **Clinical Trial Consideration**
   - Offered referral to ongoing trials evaluating KRAS G12C/G12V selective inhibitors in combination with immune checkpoint blockade; patient expressed interest but prefers standard of care at this juncture.

7. **Follow‑Up Timeline**
   - Weekly visits during chemoradiation for symptom assessment, toxicity grading (CTCAE v5.0), and laboratory monitoring.  
   - Post‑chemoradiation reassessment appointment scheduled 4weeks after completing radiation to finalize surgical timing.  
   - Ongoing survivorship education concerning smoking avoidance, vaccination updates (influenza, COVID‑19, pneumococcal), and psychosocial resources.

### Chief Complaint
Routine interval follow‑up; review of post‑chemoradiation CT chest obtained today.

### History of Present Illness
David is a 49‑year‑old man who was diagnosed at age 47 with stage IIIA (cT2bN1M0) large‑cell carcinoma of the left upper lobe (LU​L). He completed concurrent chemoradiotherapy 6weeks ago consisting of weekly carboplatin AUC2 + paclitaxel 45mg/m² together with 60Gy in 30 fractions delivered via IMRT. During treatment he experienced Grade2 esophagitis (managed conservatively with topical lidocaine slurry and dietary modification) and Grade3 thrombocytopenia (platelets nadir 62×10⁹/L, required a brief transfusion course). Both toxicities fully resolved by week4 post‑CRT.

He presents today for review of the most recent contrast‑enhanced CT chest performed 2weeks after completion of CRT. The scan demonstrates marked shrinkage of the LU​L mass from 5.0cm to 2.8cm (longest axial dimension) with central cavitation suggestive of necrosis. The previously avid ipsilateral hilar node (station10L) is no longer visualized. No new parenchymal lesions, pleural effusions, or mediastinal adenopathy are seen. Radiographically this meets criteria for a Partial Response (PR) per RECIST1.1.

He denies cough, dyspnea, hemoptysis, dysphagia, fevers, chills, weight change, or night sweats since finishing RT. His performance status remains ECOG0. He feels “back to baseline” aside from occasional mild throat soreness that has improved.

### Imaging Results (Contrast‑Enhanced Chest CT, 2 wks post‑CRT)
- **Primary Lesion (Left Upper Lobe):** Residual solid component measuring 2.8cm (previous 5.0cm). Central low attenuation suggests necrotic cavity. Margins smooth, without spiculations.
- **Hilar Nodes:** Station10L node absent; no other enlarged mediastinal stations (5,6,7 negative).
- **Pleura:** No effusion or thickening.
- **Other Lung Parenchyma:** No additional nodules or infiltrates.
- **Upper Abdomen:** Unchanged hepatic steatosis; spleen normal.

Interpretation: Marked volumetric regression compatible with favorable biologic response to combined modality therapy. No evidence of progression.

### Assessment
1. **Stage IIIA large‑cell carcinoma of left upper lobe**, cT2bN1M0  now post‑CRT PR, pending pathological staging. Molecular profile: KRAS G12V, STK11 loss, KEAP1 mut, TP53 Y220C, low‑level METex14 skip; PD‑L1 10%.  
   - Current disease burden markedly reduced; patient maintains excellent functional reserve (ECOG0, PFTs pending).  
2. **Treatment‑related toxicities:** Resolved Grade2 esophagitis, resolved Grade3 thrombocytopenia. No ongoing sequelae.  
3. **Hypertension, hyperlipidemia**  stable on current regimen.

### Plan
1. **Surgical Management**
   - Proceed with curative intent left upper lobectomy with systematic mediastinal lymphadenectomy (stations5,6,7,10L) once pre‑operative work‑up cleared.
   - Order Pulmonary Function Tests (spirometry, DLCO) within the next week; target FEV1 ≥80% predicted and DLCO ≥70%.
   - Cardiac clearance (EKG ± stress test) due to age >45 despite lack of cardiac symptoms.
   - Discuss operative timing with Thoracic Surgery—target operation ∼4–6weeks post‑CRT to allow tissue recovery while avoiding undue delay.

2. **Adjuvant Considerations**
   - Given complete metabolic response and absence of nodal disease on imaging, adjuvant chemotherapy is not planned unless intra‑operative pathology reveals unexpected residual disease (>pT2a or nodal positivity).  
   - Continue close surveillance per NCCN guidelines: CT chest q3–4mo for the first year post‑resection.

3. **Supportive Care**
   - Reinforce nutrition counseling; encourage protein‑rich diet to aid wound healing.
   - Prescribe oral rinses (chlorhexidine gluconate) prophylactically for potential post‑op mucosal irritation.
   - Encourage continued aerobic activity as tolerated; avoid heavy lifting >10lb for 4wk post‑op.

4. **Follow‑up Labs**
   - Repeat CBC/CMP 1week prior to scheduled surgery to confirm hematologic adequacy.
   - Monitor fasting lipid panel annually; blood pressure check at each visit.

5. **Education & Counseling**
   - Reviewed expected peri‑operative course, risks (bleeding, air leak, infection) and benefits of achieving R0 resection.
   - Emphasized importance of smoking abstinence (patient never smoked) and avoidance of vaping/e-cigarettes.
   - Provided printed material regarding postoperative pulmonary rehabilitation.

**Next Appointment:** Return in 2weeks for PFT results and pre‑operative clearance documentation. Contact office sooner if new respiratory symptoms develop.

### CHIEF COMPLAINT
Routine postoperative evaluation following left upper lobectomy with mediastinal lymphadenectomy for previously diagnosed large‑cell carcinoma of the left upper lobe.

---

### HISTORY OF PRESENT ILLNESS
David is a 49‑year‑old man who presents today for his first postoperative oncology appointment approximately **four weeks** after undergoing a left upper lobectomy with systematic mediastinal LN dissection (stations 5,6,7,10L). He recovered uneventfully from surgery, reporting minimal incisional discomfort controlled with acetaminophen PRN. No dyspnea, cough, hemoptysis, chest pain, dysphagia, or constitutional symptoms were endorsed. His performance status remains excellent (ECOG 0). 

He completed definitive concurrent chemoradiotherapy twelve months ago consisting of weekly carboplatin (AUC2) and paclitaxel (45mg/m²) combined with 60Gy in 30 fractions. During that course he experienced grade2 esophagitis and transient grade3 thrombocytopenia, both resolved without sequelae. Pre‑surgical staging PET/CT documented a solitary left upper lobe mass (≈5cm) with a single ipsilateral hilar node, staged clinically as cIII‑A (cT2bN1M0). The operative pathology disclosed a residual focus of large‑cell carcinoma measuring 1.9cm, negative radial margins (R0), and **no metastatic involvement in 12 examined mediastinal nodes** (ypT1bN0). Molecular profiling of the original biopsy had shown KRASG12V, STK11 loss, KEAP1 mutation, TP53Y220C, and low‑level MET exon14 skipping; PD‑L1 expression was 10%.

Given the absence of viable nodal disease, clear margins, and limited residual tumor size, the multidisciplinary team elected close radiographic surveillance rather than immediate adjuvant systemic therapy.

### IMAGING RESULT SUMMARY
Post‑operative contrast‑enhanced chest CT obtained 3weeks post‑lobectomy (reviewed):  
 Surgical bed demonstrates expected postsurgical changes with linear scarring; no residual soft tissue density.  
 Mediastinum: No enlarged lymph nodes; stations sampled remain unchanged.  
 No pleural effusion or pneumothorax.  
Impression: Complete macroscopic resection (R0) with no detectable residual disease.

---

### ASSESSMENT
1. **Large‑cell carcinoma of left upper lobe  Status post neoadjuvant chemoradiation and curative‑intent left upper lobectomy (ypT1bN0, R0)**  
   - Pathology confirms negative margins and zero involved nodes.  
   - Current imaging reveals no residual tumor.  
   - Given favorable pathological response, observation is appropriate.

2. **Hypertension**, well controlled.  
3. **Hyperlipidemia**, stable on statin.  

---

### PLAN
1. **Surveillance Strategy**
   * Chest CT with IV contrast every **3months** for the next year, then spacing to **every 6months** through Year3, thereafter annually per NCCN guidelines for surgically resected NSCLC.
   * Consider low‑dose screening CT annually beyond Year3 if smoking history warrants continued vigilance.

2. **Laboratory Monitoring**
   * Repeat CBC/CMP concurrently with imaging visits to detect early hematologic/hepatic toxicity—though none anticipated absent systemic therapy.
   * Lipid panel and blood pressure check at each office visit.

3. **Vaccinations & Preventive Care**
   * Annual influenza vaccine; COVID‑19 booster per CDC guidance.
   * Pneumococcal vaccination series up to date (PCV13 + PPSV23).

4. **Lifestyle Counseling**
   * Continue abstinence from tobacco; reinforce benefits of remaining smoke‑free.
   * Maintain regular aerobic activity (>150minutes moderate intensity per week) and balanced diet.

5. **Adjuvant Therapy Discussion**
   * Reviewed rationale for observation versus adjuvant chemotherapy/immunotherapy. Consensus: Observation favored due to lack of nodal disease, negative margins, and adequate recovery from prior chemoradiation. Patient agrees.

6. **Follow‑up Appointment**
   * Return to clinic in **3months** for interval review and coordination of upcoming CT scan.

7. **Documentation**
   * All pathology slides archived; molecular profile retained for potential future therapeutic decision‑making (KRASG12V, STK11 loss, KEAP1 mutant, TP53Y220C). Will reassess eligibility for emerging KRAS inhibitors should recurrence occur.

### Chief Complaint
Routine survivorship/follow‑up appointment. Patient denies any new symptoms.

### History of Present Illness (HPI)
David is a 51‑year‑old man who presents today for his scheduled post‑operative/on‑therapy follow‑up approximately 3years after definitive management of a stageIIIA left upper‐lobe large‑cell lung carcinoma (ypT1bN0, R0). He reports feeling “well,” with return to baseline activities and exercise tolerance without limitation. Denies cough, dyspnea, wheeze, hemoptysis, chest pain, fever, night sweats, weight change, dysphagia, odynophagia, abdominal discomfort, nausea/vomiting, changes in bowel habits, polyuria/polydipsia, skin rash, neuropathy, or any other constitutional concerns. 

He has been fully recovered from his combined modality therapy (concurrent carbo–PTX + 60Gy thoracic RT) completed at age48, followed by left upper‑lobectomy with mediastinal LN dissection at age49. Post‑surgical pathology documented residual 1.9cm large‑cell carcinoma, 0/12 nodes involved (ypT1bN0). Surveillance computed tomography of the chest obtained at age50 demonstrated complete radiographic response with no detectable pulmonary masses or suspicious lymphadenopathy. There have been no intervening systemic therapies since then.

His performance status remains excellent (ECOG0). He continues to work full‑time as a software engineer, exercises regularly (≈150min/week moderate cardio), and adheres to a balanced diet. No tobacco use since quitting at age46; occasional alcohol consumption (<2 drinks per week).

### Imaging Results

Most recent cross‑sectional imaging: **Chest CT (non‑contrast)** performed 6months ago (age50)  *Interpretation*: No residual parenchymal opacity in the left upper lobe operative bed, no new solid/subsolid nodules, mediastinum and hila free of enlarged nodes, no effusions. Radiology impression: “No evidence of recurrent or metastatic disease.” No additional scans ordered at today’s encounter.

### Assessment

1. **Stage‑IIIa (cT2bN1M0) Large Cell Carcinoma of Left Upper Lobe**, treated with definitive CRT  lobectomy (ypT1bN0, R0)  presently **no evidence of disease (NED)**. Ongoing remission >2yr. Molecular profiling previously disclosed KRASG12V, STK11 loss, KEAP1 mutation, TP53Y220C, low‑level MET exon‑14 skip; no actionable EGFR, ALK, ROS1 alterations. Current disease‑free interval supports continuation of standard surveillance rather than adjuvant systemic therapy.

2. **Performance status/ECOG0**, fully functional, no treatment‑related sequelae.

3. **Preventive health**  Up‑to‑date immunizations (influenza annually, COVID‑19 booster series, pneumococcal PCV20 administered at age49). Screening colonoscopy due at age55 (patient plans accordingly). Low cardiovascular risk; lipid profile modestly elevated LDL—continue dietary counseling.

### Plan

| Item | Details |
|------|---------|
| **Surveillance Imaging** | Schedule contrast‑enhanced Chest CT in 6months (approx. age52) per NCCN guideline for StageI NSCLC post‑resection. Consider low‑dose CT annual thereafter if interim scans remain negative. |
| **Laboratory Monitoring** | Repeat CBC/CMP and serum CEA concurrently with imaging. Monitor fasting glucose quarterly given emerging data linking KRAS‑mutant tumors and metabolic derangement (though patient currently euglycemic). |
| **Lifestyle Counseling** | Reinforce abstinence from tobacco (maintain quit status). Encourage ≥150min/week aerobic activity, Mediterranean‑style diet, limit processed red meat. Discuss sun protection and vitamin D supplementation (25‑OH level pending). |
| **Vaccinations** | Ensure seasonal influenza vaccine before fall season; verify tetanus-diphtheria boosters up to date. |
| **Psychosocial Support** | Offer referral to survivorship support group; screen PHQ‑9 (score 2)  no depression. |
| **Future Therapeutic Planning** | Documented KRASG12V mutation positions him for eligibility in ongoing KRAS‑targeted trials (e.g., adagrasib, combination KRAS inhibitor + SHP2 blockade). Counsel patient that such options will be revisited if recurrence occurs. |
| **Follow‑up Appointment** | Return to clinic in 3months for symptom check and labs; imaging result discussion to occur at subsequent visit when CT available. |
| **Documentation** | Update EMR problem list to reflect “Post‑lung cancer resection  disease‑free” and “KRAS G12V mutant NSCLC”. Add current medication list (none chronic beyond multivitamin). Record allergy status  NKDA. |

### TECHNIQUE
Multidetector computed tomography of the chest was performed without intravenous contrast due to renal function considerations. Axial images were obtained from the lung apices through the adrenal glands with ≤1mm collimation and reconstructed in standard soft‐tissue (width 400HU, level 40HU) and high‑frequency lung kernels (width −600HU, level −100HU). Sagittal and coronal multiplanar reformats were generated for anatomic correlation. No motion artifacts compromising image quality were observed.

Comparison made to prior imaging:

* Baseline staging CT (age47) showing a 5.0cm left upper lobe mass with ipsilateral hilar adenopathy.  
* Post‑induction chemoradiation CT (age49) demonstrating reduction to 2.8cm.  
* Surveillance CTs at ages50–52 documenting complete response following left upper lobectomy (R0, ypT1bN0).  

---

### FINDINGS  

#### **Pulmonary Parenchyma**
- **Right Middle Lobe:** There is a solitary, partially solid pulmonary nodule measuring *approximately 1.2×1.0cm* (long axis × short axis) located centrally within the posterior segment. The lesion demonstrates mixed attenuation with a peripheral ground‑glass halo surrounding a central higher‑density focus suggestive of a solid component comprising roughly 35% of the total volume. Margins are mildly irregular but there is no definitive spiculation or cavitation. No associated bronchovascular distortion is evident. This represents a newly detected abnormality when compared with the most recent surveillance CT (age52), where no such nodule was visualized.

- **Left Lung:** Status post left upper lobectomy with surgical changes including staple lines and fibrosis along the resection margin. No residual parenchymal masses or consolidations. Scarring appears stable relative to prior examinations.

- **Other Lobes:** Right upper and lower lobes, as well as remaining left lung fields, demonstrate normal aeration without additional focal opacities, infiltrates, or cystic change.

#### **Mediastinum & Hila**
- Central airways are patent. No endobronchial lesions identified.
- Mediastinal fat planes preserved. No enlarged mediastinal, prevascular, or para‑aortic lymph nodes (>1cm short-axis). Bilateral hila appear unremarkable; no evidence of recurrent hilar adenopathy.

#### **Pleural Space**
- No pleural effusion, thickening, or plaques. Surgical clips noted adjacent to left hemithorax correlating with prior lobectomy.

#### **Osseous Structures**
- Visualized ribs, vertebrae, scapulae, and clavicles show no destructive lesions, cortical disruption, or suspicious sclerosis.

#### **Upper Abdomen (included portion)**
- Upper abdominal cuts reveal normal-sized adrenals without enlargement or heterogeneity. No hepatic or splenic lesions appreciably seen within limited field-of-view.

#### **Incidental Findings**
- Small (<5mm) calcified granuloma in the right lower lobe, unchanged from prior exams—stable benign appearance.
- Mildly increased bibasilar subsegmental atelectasis likely secondary to shallow breathing; otherwise lungs clear.

---

### IMPRESSION
1. New 1.2cm partly solid (mixed ground‑glass/solid) nodule in the right middle lobe, absent on prior imaging  concerning for early metastatic recurrence versus second primary lung neoplasm in the setting of known KRAS‑mutant large‑cell carcinoma. Correlation with prior imaging timeline and consideration for tissue sampling recommended.

## Chief Complaint  
Routine follow‑up after 8weeks of sotorasib therapy for recurrent KRAS‑mutant non‑small cell lung cancer (right middle lobe lesion).

## History of Present Illness  
David presents today for his scheduled interval assessment following initiation of sotorasib 960mg PO QD eight weeks ago for a solitary right‑middle‑lobe subsolid nodule (initial size 1.2cm) detected on surveillance chest CT at age53. At the start of therapy he experienced Grade2 watery diarrhea lasting approximately 5days, managed conservatively with loperamide and fluid replacement, and Grade1 transaminase elevation (AST 52U/L, ALT 61U/L) that peaked at week4 and subsequently returned to baseline. He denied recurrence of diarrheal symptoms since week5, reports normal bowel habits, and feels “generally well.” No fevers, chills, cough, dyspnea, chest pain, weight change, or neurologic complaints were noted. His performance status remains ECOG0.

He continues sotorasib uninterrupted and denies missed doses. Current concerns focus on reassurance regarding radiographic response and discussion of continued safety monitoring.

## Imaging Results  

**Chest CT (non‑contrast, thin slice)**  Performed 8weeks after starting sotorasib:

* Right middle lobe subsolid nodule measured **0.6cm** (long axis), previously 1.2cm. Morphologically unchanged except for slight attenuation increase suggestive of fibrosis/reduction in cellularity. No cavitation.
* No additional pulmonary nodules, consolidations, pleural effusion, or atelectasis.
* Mediastinum: No enlarged stations; largest short-axis dimension 5mm (stable vs prior).
* Upper abdomen visualized incidentally  unremarkable.

Interpretation: **Partial response** according to RECIST v1.1 criteria (≥30% reduction in longest diameter). Radiologist comment: “Findings compatible with therapeutic effect; continue close imaging surveillance.”

## Assessment  

1. **Recurrent KRAS‑G12V mutated NSCLC, right middle lobe subsolid nodule**  Currently demonstrating radiographic partial response to sotorasib after 8weeks of therapy. Clinically asymptomatic, ECOG0.  
2. **Treatment‑related toxicities**  Prior Grade2 diarrhea and transient Grade1 transaminitis have resolved; no active adverse events presently.  
3. **Hypertension, hyperlipidemia**  Controlled on current regimen.  
4. **Overall functional status**  Excellent; maintains regular employment and exercise.

## Plan  

| Item | Details |
|------|---------|
| **Continue sotorasib** | Maintain Lumakras® 960mg PO daily. Emphasize adherence; advise patient to contact office promptly if ≥Grade2 GI upset, persistent elevated LFTs, or unexplained fatigue occurs. |
| **Safety Monitoring** |  CBC, CMP, fasting glucose at next monthly visit.<br>• Liver function tests repeat in 4weeks (already within Grade1). |
| **Imaging Surveillance** | Schedule contrast‑enhanced chest CT in 8weeks (approximately 16weeks total on therapy) to confirm durability of response; thereafter every 12weeks while on sotorasib unless progression suspected clinically. |
| **Supportive Care** | Continue OTC loperamide PRN for breakthrough loose stools (<3 days). Encourage adequate hydration and balanced diet. |
| **Vaccinations** | Ensure up‑to‑date influenza vaccine (administered annually) and COVID‑19 booster per CDC schedule; no live vaccines while on targeted agent. |
| **Lifestyle Counseling** | Reinforce smoking abstinence, maintain moderate aerobic activity (150min/week), limit alcohol intake. |
| **Follow‑up Appointment** | Return in 4weeks for laboratory review and symptom check; sooner if acute issues arise. |
| **Documentation** | Update electronic problem list to reflect “NSCLC  KRAS G12V  Partial Response to sotorasib” and record current toxicity profile as *Resolved*. |

**Patient:** David Kim**Sex/Age:** Male, 55years  
**Referring Physician:** Medical Oncology  
**Study Date:** [Date omitted per protocol]  
**Indication:** Surveillance of previously treated right‑middle‑lobe pulmonary nodule (KRAS‑mutant non‑small‑cell lung cancer) following response to sotorasib therapy.  

---

### Technique
Whole‑body ^18F‑FDG PET acquired 60minutes after intravenous administration of 370MBq (10mCi) FDG. Low‑dose helical CT obtained for attenuation correction and anatomical correlation (120kVp, automated mA modulation, slice thickness 3mm). Images reconstructed with standard OSEM algorithm; axial, coronal, and sagittal fused datasets reviewed. Prior PET/CT examinations dated at ages 54 and 52 were available for comparative evaluation.

--- 

### Findings  

#### Thorax  
- **Right Middle Lobe Pulmonary Nodule:** Subsolid nodule measuring 0.6×0.5cm (previously 0.6cm on the most recent scan). Mild FDG avidity observed with maximum standardized uptake value (**SUVmax 2.3**, compared with SUVmax2.5 on the preceding examination). Morphologically unchanged contour, without spiculated margins or cavitation. No associated bronchial obstruction or atelectasis.  
- **Left Lung & Mediastinum:** Post‑lobectomy changes in the left upper lobe with complete fibrosis; no residual soft tissue abnormality. No enlarged mediastinal or hilar lymph nodes; all stations 6mm in short axis, physiologic FDG activity.  
- **Pleura & Chest Wall:** Unremarkable; no pleural effusion or thickening.  

#### Upper Abdomen  
- Liver, spleen, adrenal glands, pancreas unremarkable; physiological hepatic and splenic FDG distribution. No focal metabolic abnormalities detected.  

#### Pelvis & Lower Extremities  
- Normal marrow signal intensity throughout vertebral bodies and proximal femora; expected heterogeneous uptake related to age. No osseous lesions identified.  

#### Additional Observations  
- No evidence of metabolically active metastatic disease in bone, brain (limited CT component), or soft tissues.  
- Physiological urinary excretion of tracer noted.  

--- 

### Comparison
Findings are essentially unchanged relative to the PET/CT performed eight weeks earlier (age54): the right‑mid‑lung nodule remains stable in size and demonstrates persistently low‑grade FDG uptake. There has been no emergence of new FDG‑avid foci elsewhere in the body since baseline staging at age47.

--- 

### Impression  
1. Stable low‑grade FDG uptake in the right middle‑lobe subsolid nodule (0.6cm, SUVmax~2.3). Imaging appearance compatible with indeterminate persistent disease versus benign inflammatory change; however, stability over successive scans favors a controlled neoplastic process under current KRAS‑directed therapy (sotorasib).  
2. No new FDG‑avid lesions suggestive of locoregional progression or distant metastasis.  
3. Overall disease burden unchanged; continued close radiographic surveillance recommended in conjunction with ongoing systemic therapy.

## Chief Complaint  
“Feeling a little more tired than usual over the last few weeks.”  

---  

## History of Present Illness (HPI)  
David is a 56‑year‑old man who presents for routine follow‑up while on **sotorasib 960mg PO daily**, started 13 months ago for recurrent KRASG12V‑mutant non‑small cell lung cancer (NSCLC) involving a right middle‑lobe subsolid nodule. Since initiating therapy he has tolerated treatment reasonably well aside from transient Grade2 diarrhea and Grade1 transaminitis early in the course, both of which resolved without dose modification.

Over the preceding month he has noticed *mild generalized fatigue* that does not limit his activities; he continues to perform ADLs independently, walks ≥30 minutes daily, and remains employed full‑time as a software engineer (ECOG performance status = 0). No associated dyspnea, cough, fever, weight change, night sweats, abdominal pain, nausea/vomiting, melena, hematochezia, dysuria, joint pains, rash, or neurologic symptoms. Denies new medication changes, alcohol intake increase, or travel exposures.

He adheres to sotorasib dosing schedule, takes occasional loperamide PRN for loose stools (last used >4weeks ago), and monitors blood sugars per home glucometer (most readings 90–110mg/dL). No episodes of hypoglycemia. 

Overall impression: Stable disease on systemic therapy with emerging fatigue likely multifactorial—possible cumulative effect of KRAS inhibitor, subtle anemia of chronic disease, or lifestyle stressors. No evidence of acute toxicity warranting interruption.

## Radiology Summary  

**Most Recent Chest CT (performed 4weeks ago):** Thin‑slice axial images demonstrate persistence of a solitary right middle‑lobe subsolid nodule measuring **0.62cm x 0.58cm** (stable compared with prior measurement of 0.61cm). No interval development of additional pulmonary nodules, consolidations, pleural effusion, or mediastinal/hilar lymphadenopathy. Lung parenchymal architecture otherwise unremarkable.

**Prior PET/CT (age55, 6months earlier):** Showed low‑grade FDG avidity within the aforementioned nodule (SUVmax ≈2.1) with no new foci elsewhere. Correlates with indolent behavior under sotorasib.

Interpretation: Disease remains radiographically stable (RECIST criteria: non‑progressive).

---  

## Assessment  

1. **KRASG12V‑mutant NSCLC, recurrent, right middle‑lobe subsolid nodule  stable disease** on sotorasib therapy.  
   - Molecular profile includes co‑alterations (STK11 loss, KEAP1 mutation, TP53 Y220C) which confer modest resistance risk but response thus far sustained.  
   - Current imaging demonstrates stability; laboratory parameters acceptable apart from minimal transaminase rise and borderline drop in hemoglobin.  

2. **Treatment‑related fatigue (Grade1)**  likely multifactorial (chronic therapy exposure, mild anemia, psychosocial factors).  

3. **Hypertension, hyperlipidemia**  controlled on current regimen.  

4. **Preventive health:** Up‑to‑date immunizations (influenza annually, COVID‑19 booster series).  

---  

## Plan  

| Item | Details |
|------|----------|
| **Continue sotorasib** | Maintain 960mg PO daily. Reinforce adherence. No dose reduction required at this time. |
| **Monitor labs** | Repeat CBC/CMP in 4weeks; specifically watch hemoglobin trending and hepatic enzymes. Consider iron studies if Hb falls below 12g/dL. |
| **Manage fatigue** |  Counsel regarding sleep hygiene, balanced nutrition, moderate aerobic activity.<br>• Offer trial of vitamin B12 level check; supplement if deficient.<br>• Discuss possibility of low‑dose methylphenidate if fatigue becomes disabling (shared decision). |
| **Supportive care** | Keep loperamide available PRN; educate patient to contact office if ≥3 watery stools/day lasting >48hrs. |
| **Imaging follow‑up** | Schedule thin‑slice chest CT in 12weeks (±2wks) to reassess nodule size; interim PET/CT reserved for symptomatic progression or significant growth (>20%). |
| **Vaccinations** | Verify influenza vaccine administered; arrange COVID‑19 booster per CDC guidance. |
| **Comorbidity optimization** | Blood pressure target <130/80 mmHg  continue lisinopril; lipid goal LDL <70 mg/dL  discuss intensifying statin if ASCVD risk escalates. |
| **Referral** | None presently; consider referral to cardio‑oncology if hypertensive burden increases secondary to sotorasib (rare). |
| **Next appointment** | Return in 4weeks for labs review; sooner if new symptoms develop (e.g., worsening fatigue, GI upset, jaundice, shortness of breath). |
| **Documentation** | Updated problem list entered into EMR; consent reaffirmed for continued off‑label KRAS inhibition. |

### History of Present Illness (HPI)

David is a 58‑year‑old man with a remote history of StageIIIA left upper‐lobe large‑cell carcinoma (treated with definitive CRT  lobectomy  observation) who subsequently developed a solitary right‑middle‑lobe subsolid nodule at age53. Molecular profiling disclosed KRASG12V, prompting initiation of sotorasib 960mg PO daily (Lumakras®) at age53. He has been on continuous therapy for **≈5years**, achieving radiographic partial response (nodule reduced from 1.2cm  0.6cm) and thereafter maintaining stable disease over multiple assessments.

Therapy‑related toxicities have been modest:

* Grade2 watery diarrhea (managed with dietary modification & loperamide PRN)  resolved by month3 of therapy.  
* Grade1 transaminase elevation (AST/ALT ≤2× ULN)  remained static, monitored quarterly.  
* New onset Grade3 hyperglycemia at age57 necessitating initiation of basal–bolus insulin (glargine20U nightly, lispro sliding scale).

He reports **mild intermittent fatigue** (no impact on ADLs), **well‑controlled blood sugars** on his insulin regimen (fasting BG 110‑130mg/dL), **no abdominal pain**, **no dysphagia**, and **no dyspnea**. Denies fevers, chills, night sweats, weight change (>2kg), cough, hemoptysis, or neurologic symptoms.

Overall functional status remains excellent (ECOG0). He continues to work full‑time as a software engineer and engages in regular aerobic exercise (≥150min/week).
