Tissue fixed in neutral buffered formalin for ≥24 hours 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:

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 exon 14 skipping** transcripts suggest a minor subclone harboring this alteration. While MET exon 14 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 exon 14 skipping via orthogonal methods (e.g., RT‑PCR) was not performed due to limited tissue availability. ### Reporting Physician Dr. ***[Molecular Pathology Fellow]*​ Department of Pathology & Laboratory Medicine *(Signature electronically generated)* --- *End of Report*" 2,74643,2020-01-03,"**PATIENT:** David Kim Sex: Male Age: 47 **REFERRING PHYSICIAN:** Pulmonology / Oncology Team --- ### EXAMINATION **Modality:** Integrated whole‑body **^18F‑FDG Positron Emission Tomography / Computed Tomography (PET/CT)** **Protocol Summary:** Patient fasted ≥6 h, blood glucose measured at 92 mg/dL before intravenous administration of 370 MBq (≈10 mCi) ^18F‑FDG.

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 (segment 1) 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 exon 14 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 × 4.5 cm spiculated mass involving the posterior segment of the left upper lobe with associated atelectasis, and a solitary enlarged ipsilateral hilar lymph node measuring 1.8 cm. 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_max ≈ 8). Brain MRI was unremarkable. Overall staging is cT2b N1 M0 → 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 (<2 drinks/week). There is no personal or familial history of malignancy aside from a paternal uncle with colorectal cancer diagnosed at age 68. --- ## Review of Systems *General:* Denies fevers, chills, recent infections, unintended weight change. *Respiratory:* No chronic cough, sputum production, dyspnea, pleuritic chest pain, or hemoptysis. *Cardiovascular:* No palpitations, orthopnea, edema. *GI:* Normal appetite, bowel habits regular, no nausea/vomiting. *Genitourinary:* No dysuria, frequency changes. *Neurologic:* No headaches, dizziness, seizures. *Skin:* No rashes or lesions.

One ipsilateral hilar LN measures 1.8 cm short axis, mildly hyperattenuating. No contralateral hilar or mediastinal nodes >1 cm. 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_max ≈ 8). No extrathoracic foci of increased metabolism. Interpretation aligns with clinically staged cT2b N1 M0 disease. --- ## Assessment 1. **Stage III A (cT2b N1 M0) left‑sided large‑cell carcinoma with neuroendocrine features**, harboring KRAS G12V, STK11 loss, KEAP1, TP53 mutations, low‑level MET exon 14 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 (ECOG 0), 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 stage IIIA 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 stations 5–7. Planned dose: **60 Gy in 30 fractions** (2 Gy/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 AUC 2 IV weekly** + **Taxol 45 mg/m² IV weekly** administered on days 1, 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 < 100 000/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 6‑8 weeks), 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 (stations 5, 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 4 weeks after completing radiation to finalize surgical timing. - Ongoing survivorship education concerning smoking avoidance, vaccination updates (influenza, COVID‑19, pneumococcal), and psychosocial resources. **Signature:** _________________________ Dr. [Oncologist Name], MD Board Certified Medical Oncologist Date: *(to be inserted)*" 4,74643,2020-01-05,"**Oncology Progress Note – Follow‑Up After Definitive Chemoradiation** **Patient:** David Kim **MRN:** [redacted] **DOB:** **[age 49]** **Date:** *[to be inserted]* --- ### 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 (cT2b N1 M0) large‑cell carcinoma of the left upper lobe (LU​L). He completed concurrent chemoradiotherapy 6 weeks ago consisting of weekly carboplatin AUC 2 + paclitaxel 45 mg/m² together with 60 Gy in 30 fractions delivered via IMRT. During treatment he experienced Grade 2 esophagitis (managed conservatively with topical lidocaine slurry and dietary modification) and Grade 3 thrombocytopenia (platelets nadir 62 × 10⁹/L, required a brief transfusion course). Both toxicities fully resolved by week 4 post‑CRT. He presents today for review of the most recent contrast‑enhanced CT chest performed 2 weeks after completion of CRT. The scan demonstrates marked shrinkage of the LU​L mass from 5.0 cm to 2.8 cm (longest axial dimension) with central cavitation suggestive of necrosis. The previously avid ipsilateral hilar node (station 10L) 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 RECIST 1.1. He denies cough, dyspnea, hemoptysis, dysphagia, fevers, chills, weight change, or night sweats since finishing RT. His performance status remains ECOG 0. He feels “back to baseline” aside from occasional mild throat soreness that has improved. ### Review of Systems | System | Positive / Negative | |--------|----------------------| | Constitutional | Denies fever, chills, unexplained weight loss | | Respiratory | No cough, sputum, dyspnea, wheeze | | Cardiovascular | No chest pain, palpitations | | GI | No nausea/vomiting, bowel habits regular | | GU | No dysuria, frequency | | Neurologic | No headache, dizziness | | Dermatologic | No rash | | Endocrine | No polyuria/polydipsia | ### Past Medical History *(selected)* - Large‑cell lung carcinoma, left upper lobe, diagnosed 24 months ago - Hypertension, well controlled on lisinopril 20 mg daily - Hyperlipidemia, on atorvastatin 40 mg nightly ### Surgical History Appendectomy (childhood) ### Social History Never smoker (never >100 cigarettes lifetime). Occasional alcohol (<2 drinks/week). Works as software engineer; physically active (jogging 3–4 times/wk).

Central low attenuation suggests necrotic cavity. Margins smooth, without spiculations. - **Hilar Nodes:** Station 10L 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**, cT2b N1 M0 → 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 (ECOG 0, PFTs pending). 2. **Treatment‑related toxicities:** Resolved Grade 2 esophagitis, resolved Grade 3 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 (stations 5, 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 ∼4–6 weeks 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 q3–4 mo 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 >10 lb for 4 wk post‑op. 4. **Follow‑up Labs** - Repeat CBC/CMP 1 week 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 2 weeks for PFT results and pre‑operative clearance documentation. Contact office sooner if new respiratory symptoms develop. --- *Prepared by:* Dr. ***[Name], MD*** Medical Oncology – Thoracic Malignancies Signature: ______________________ Date: ____________" 5,74643,2020-01-06,"**Oncology Progress Note – Post‑Operative Follow‑Up** **Patient:** David Kim **MRN:** [redacted] **DOB:** [redacted] --- ### 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 (AUC 2) and paclitaxel (45 mg/m²) combined with 60 Gy in 30 fractions. During that course he experienced grade 2 esophagitis and transient grade 3 thrombocytopenia, both resolved without sequelae. Pre‑surgical staging PET/CT documented a solitary left upper lobe mass (≈5 cm) with a single ipsilateral hilar node, staged clinically as cIII‑A (cT2b N1 M0). The operative pathology disclosed a residual focus of large‑cell carcinoma measuring 1.9 cm, negative radial margins (R0), and **no metastatic involvement in 12 examined mediastinal nodes** (ypT1b N0). Molecular profiling of the original biopsy had shown KRAS G12V, STK11 loss, KEAP1 mutation, TP53 Y220C, and low‑level MET exon 14 skipping; PD‑L1 expression was 10 %.

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 3 years after definitive management of a stage IIIA 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 + 60 Gy thoracic RT) completed at age 48, followed by left upper‑lobectomy with mediastinal LN dissection at age 49. Post‑surgical pathology documented residual 1.9 cm large‑cell carcinoma, 0/12 nodes involved (ypT1bN0). Surveillance computed tomography of the chest obtained at age 50 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 (ECOG 0). He continues to work full‑time as a software engineer, exercises regularly (≈150 min/week moderate cardio), and adheres to a balanced diet. No tobacco use since quitting at age 46; occasional alcohol consumption (<2 drinks per week). ### Review of Systems (ROS) | System | Positive / Negative | |--------|----------------------| | Constitutional | No fevers, chills, night sweats, unexplained weight loss or gain | | HEENT | No sore throat, hoarseness, sinus congestion | | Respiratory | No cough, sputum production, dyspnea, pleuritic pain | | Cardiovascular | No chest pressure, palpitations, edema | | Gastrointestinal | Normal appetite, no nausea, vomiting, dyspepsia, melena, hematochezia | | Genitourinary | No dysuria, frequency, nocturia | | Musculoskeletal | No myalgias, arthralgias, bone pain | | Neurologic | No headaches, dizziness, peripheral neuropathy | | Dermatologic | No rashes, pruritus | | Endocrine | No polydipsia/polyuria, thyroid symptoms | | Hematologic/Lymphatic | No bruising, bleeding, swollen glands | Overall ROS is unremarkable. ### Physical Examination - **Vitals:** BP 122/78 mmHg, HR 68 bpm, RR 14/min, Temp 36.8°C, SpO₂ 98% RA, BMI 26 kg/m². - **General:** Well‑appearing, NAD, alert & oriented ×3, ECOG 0. - **HEENT:** Normocephalic, atraumatic, mucous membranes moist. - **Neck:** Supple, no cervical adenopathy. - **Cardiovascular:** Regular rate/rhythm, S₁S₂ audible, no murmurs, rubs, gallops. - **Respiratory:** Clear breath sounds bilaterally, no crackles, wheezes, or rhonchi.

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 >2 yr. Molecular profiling previously disclosed KRAS G12V, STK11 loss, KEAP1 mutation, TP53 Y220C, 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/ECOG 0**, fully functional, no treatment‑related sequelae. 3. **Preventive health** – Up‑to‑date immunizations (influenza annually, COVID‑19 booster series, pneumococcal PCV20 administered at age 49). Screening colonoscopy due at age 55 (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 6 months (approx. age 52) per NCCN guideline for Stage I 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 ≥150 min/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 KRAS G12V 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 3 months 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).

Axial images were obtained from the lung apices through the adrenal glands with ≤1 mm collimation and reconstructed in standard soft‐tissue (width 400 HU, level 40 HU) and high‑frequency lung kernels (width −600 HU, level −100 HU). 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 (age 47) showing a 5.0 cm left upper lobe mass with ipsilateral hilar adenopathy. * Post‑induction chemoradiation CT (age 49) demonstrating reduction to 2.8 cm. * Surveillance CTs at ages 50–52 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 × 1.0 cm* (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 (age 52), 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 (>1 cm 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 (<5 mm) 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 1.2 cm 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. 2. Stable post‑lobectomy left lung with no residual or recurrent disease. 3. No mediastinal/hilar lymphadenopathy, pleural effusion, or osseous metastases identified. 4. Incidental small calcified granuloma unchanged; clinically insignificant. --- **Prepared By:** ___________________________________ Board‑Certified Radiologist, MD [Institution Name] *(Signature withheld per documentation policy)* " 9,74643,2020-01-10,"**Oncology Progress Note – Follow‑Up Visit** --- ### Patient **Name:** David Kim **MRN:** ██████ **DOB:** ████‑██‑██ **Age:** 54 **Sex:** Male ### Date of Service [Date omitted – to be inserted electronically] --- ## Chief Complaint Routine follow‑up after 8 weeks 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 960 mg PO QD eight weeks ago for a solitary right‑middle‑lobe subsolid nodule (initial size 1.2 cm) detected on surveillance chest CT at age 53. At the start of therapy he experienced Grade 2 watery diarrhea lasting approximately 5 days, managed conservatively with loperamide and fluid replacement, and Grade 1 transaminase elevation (AST 52 U/L, ALT 61 U/L) that peaked at week 4 and subsequently returned to baseline. He denied recurrence of diarrheal symptoms since week 5, 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 ECOG 0. He continues sotorasib uninterrupted and denies missed doses. Current concerns focus on reassurance regarding radiographic response and discussion of continued safety monitoring. ## Review of Systems *(pertinent positives & negatives)* | System | Positive / Negative | |--------|----------------------| | Constitutional | Denies fever, night sweats, recent weight loss or gain | | Respiratory | No cough, sputum production, hemoptysis, dyspnea, wheeze | | Cardiovascular | No chest pain, palpitations, edema | | Gastrointestinal | Diarrhea resolved; occasional mild nausea, no vomiting | | Hepatic/Biliary | No abdominal pain, jaundice; liver enzymes normalized | | Endocrine | No polyuria/polydipsia; fasting glucose last month 98 mg/dL | | Musculoskeletal | No myalgias or arthralgias | | Neurologic | No headaches, dizziness, neuropathy | | Dermatologic | No rash or skin changes | ## Past Medical History * **Non–Small Cell Lung Cancer**, Large‑cell histology, KRAS G12V mutant, Stage IIIA at presentation (left upper lobe) → definitive chemoradiation + lobectomy → disease‐free until year 53 when isolated contralateral subsolid nodule appeared. * Hypertension – controlled on lisinopril 20 mg daily. * Hyperlipidemia – rosuvastatin 10 mg nightly. ## Surgical History * Left upper lobectomy with mediastinal LN dissection (ypT1bN0) – age 49, uncomplicated recovery. ## Family History * Father died of myocardial infarction at 68. * Mother alive, hypertension. * No known familial cancers. ## Social History * Former smoker, 15 pack‑years, quit at age 46. * Occasional alcohol (≤2 drinks/week). * Works as software engineer; sedentary desk work. * Lives with spouse; no illicit drugs. ## Allergies * NKDA (no known drug allergies) ## Medications | Medication | Dose/Frequency | Indication | |------------|---------------|-----------| | Sotorasib (Lumakras®) | 960 mg PO qd | KRAS‑mutant NSCLC | | Lisinopril | 20 mg PO qd | HTN | | Rosuvastatin | 10 mg PO hs | Dyslipidemia | | Vitamin D₃ | 2000 IU PO qd | Supplement | | Multivitamin | Daily | General health | *(Patient uses over‑the‑counter antidiarrheals PRN.)* ## Physical Examination | Parameter | Finding | |----------|---------| | Vital signs | BP 122/78 mmHg, HR 72 bpm, RR 16/min, Temp 36.8°C, SpO₂ 97% RA | | General | Well‑appearing, NAD, alert ×3 | | HEENT | Normocephalic, mucous membranes moist | | Neck | Supple, no cervical adenopathy | | Cardiac | Regular rate/rhythm, no murmurs | | Pulmonary | Clear breath sounds bilaterally, no rales/wheezes | | Abdomen | Soft, nondistended, normoactive BS, no hepatosplenomegaly | | Extremities | No edema, pulses intact | | Skin | Warm, dry, no rash | | Neuro | Grossly intact cranial nerves, strength 5/5 UE/LE, sensation preserved | ## Laboratory Data (drawn today) | Test | Result | Reference | |------|-------|-----------| | CBC w diff | WBC 6.2 ×10⁹/L, Hb 13.8 g/dL, Plt 210 ×10⁹/L | Normal | | Comprehensive Metabolic Panel | Na 138, K 4.2, Cl 102, CO₂ 24, BUN 14, Cr 0.92, Glucose 96 mg/dL, AST 31 U/L, ALT 35 U/L, Alk Phos 84 U/L, Total Bilirubin 0.6 mg/dL | Within limits | | Lipid panel | LDL 95 mg/dL, HDL 52 mg/dL, TG 115 mg/dL | Stable | | Serum CEA | 2.1 ng/mL (previous 2.3 ng/mL) | Low/normal | | Urinalysis | Neg for protein/glucose/blood | Unremarkable | All values reflect stability compared with pre‑therapy baselines; hepatic enzymes remain ≤Grade 1. ## Imaging Results **Chest CT (non‑contrast, thin slice)** – Performed 8 weeks after starting sotorasib: * Right middle lobe subsolid nodule measured **0.6 cm** (long axis), previously 1.2 cm.

Low‑dose helical CT obtained for attenuation correction and anatomical correlation (120 kVp, automated mA modulation, slice thickness 3 mm). 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 × 0.5 cm (previously 0.6 cm on the most recent scan). Mild FDG avidity observed with maximum standardized uptake value (**SUVmax ≈ 2.3**, compared with SUVmax ≈ 2.5 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 ≤ 6 mm 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 (age 54): 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 age 47. --- ### Impression 1. Stable low‑grade FDG uptake in the right middle‑lobe subsolid nodule (0.6 cm, 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. *Prepared by:* _______________________ Board‑Certified Radiologist, MD Nuclear Medicine/Pet Imaging Division " 11,74643,2020-01-12,"**Oncology Progress Note – Follow‑Up Visit** --- ### Patient Information **Name:** David Kim **MRN:** [redacted] **DOB:** [redacted] **Age:** 56 y/o **Sex:** Male --- ## 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 960 mg PO daily**, started 13 months ago for recurrent KRAS G12V‑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 Grade 2 diarrhea and Grade 1 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 >4 weeks ago), and monitors blood sugars per home glucometer (most readings 90–110 mg/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. --- ## Review of Systems (ROS) | System | Positive / Negative | |--------|---------------------| | Constitutional | +Fatigue (mild); -Weight loss, -Fever, -Chills | | HEENT | -Headache, -Vision changes, -Sore throat | | Cardiovascular | -Chest pain, -Palpitations, -Edema | | Respiratory | -Dyspnea, -Cough, -Hemoptysis | | Gastrointestinal | -Nausea/Vomiting, -Diarrhea (resolved), -Abdominal pain | | Genitourinary | -Dysuria, -Frequency, -No polyuria | | Musculoskeletal | -Myalgias, -Arthralgias | | Neurologic | -Weakness, -Sensory deficits | | Dermatologic | -Rash, -Pruritus | | Endocrine | -Polyphagia, -Polydipsia (none reported) | | Hematologic/Lymphatic | -Bleeding/bruising | --- ## Past Medical History (PMHx) - **Stage III​A Large Cell Carcinoma of Left Upper Lobe** (diagnosed age 47) → neoadjuvant carbo/Taxol + 60 Gy RT → left upper lobectomy (ypT1bN0, R0) – completed curative intent, observed thereafter. - **Recurrent KRAS G12V‑mutant NSCLC** (right middle‑lobe subsolid nodule detected age 53) → treated with sotorasib since age 53. - Hypertension (well controlled on lisinopril 20 mg QD). - Hyperlipidemia (atorvastatin 40 mg nightly). - Seasonal allergic rhinitis. --- ## Surgical & Procedural History - Right video‑assisted thoracoscopic wedge resection (biopsy) of right middle‑lobe nodule – pathology confirming persistent large‑cell histology with KRAS G12V, STK11 loss, KEAP1 mutation, TP53 Y220C; PD‑L1 10 %. - Left upper lobectomy with mediastinal LN dissection (stations 5, 6, 7, 10L) – R0, 0/12 nodes involved. --- ## Social History (SH) - Former smoker: 15 pack‑years, quit at age 46 (quit year coincident with initial diagnosis). - Alcohol: Occasional wine (<2 drinks/week). - Occupation: Software developer, sedentary work environment. - Living situation: Lives with spouse; independent ADLs. - Exercise: Regular brisk walking 3–4 times/week. --- ## Family History (FH) - Father deceased at 68 from myocardial infarction (no known malignancy). - Mother alive, 80, hypertension. - Siblings healthy. - No familial cancers reported. --- ## Allergies - NKDA (No Known Drug Allergies). --- ## Current Medications | Medication | Dose | Frequency | Indication | |------------|------|-----------|-------------| | Sotorasib | 960 mg | PO daily | KRAS‑mutant NSCLC | | Lisinopril | 20 mg | PO daily | HTN | | Atorvastatin | 40 mg | PO nightly | Dyslipidemia | | Vitamin D₃ | 2000 IU | PO daily | Supplement | | Acetaminophen PRN | 500 mg | q6h prn pain/fever | Symptom control | | Loperamide PRN | 2 mg | PO up to 4 tabs/day PRN diarrhea | Diarrhea management | --- ## Physical Examination **Vital Signs:** BP 122/78 mmHg, HR 72 bpm regular, RR 16/min, Temp 36.8°C, SpO₂ 98% RA, Weight 84 kg (BMI 27 kg/m²). **General:** Alert, oriented ×3, NAD, appears well‑nutrient. **HEENT:** Normocephalic, atraumatic; mucous membranes moist; no cervical adenopathy. **Neck:** Supple, trachea midline, no JVD. **Cardiovascular:** RRR, no murmurs, rubs, gallops.

No interval development of additional pulmonary nodules, consolidations, pleural effusion, or mediastinal/hilar lymphadenopathy. Lung parenchymal architecture otherwise unremarkable. **Prior PET/CT (age 55, 6 months 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. **KRAS G12V‑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 (Grade 1)** – 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 960 mg PO daily. Reinforce adherence. No dose reduction required at this time. | | **Monitor labs** | Repeat CBC/CMP in 4 weeks; specifically watch hemoglobin trending and hepatic enzymes.

Molecular profiling disclosed KRAS G12V, prompting initiation of sotorasib 960 mg PO daily (Lumakras®) at age 53. He has been on continuous therapy for **≈5 years**, achieving radiographic partial response (nodule reduced from 1.2 cm → 0.6 cm) and thereafter maintaining stable disease over multiple assessments. Therapy‑related toxicities have been modest: * Grade 2 watery diarrhea (managed with dietary modification & loperamide PRN) – resolved by month 3 of therapy. * Grade 1 transaminase elevation (AST/ALT ≤2× ULN) – remained static, monitored quarterly. * New onset Grade 3 hyperglycemia at age 57 necessitating initiation of basal–bolus insulin (glargine 20 U nightly, lispro sliding scale). He reports **mild intermittent fatigue** (no impact on ADLs), **well‑controlled blood sugars** on his insulin regimen (fasting BG 110‑130 mg/dL), **no abdominal pain**, **no dysphagia**, and **no dyspnea**. Denies fevers, chills, night sweats, weight change (>2 kg), cough, hemoptysis, or neurologic symptoms. Overall functional status remains excellent (ECOG 0). He continues to work full‑time as a software engineer and engages in regular aerobic exercise (≥150 min/week). --- ### Review of Systems (ROS) | System | Positive / Negative | |--------|----------------------| | Constitutional | Fatigue (mild); denies fever, chills, weight loss | | HEENT | No headache, visual changes, sore throat | | Cardiovascular | No chest pain, palpitations, edema | | Respiratory | No cough, sputum, dyspnea, wheeze | | Gastrointestinal | Occasional loose stools (<2/day); no nausea/vomiting, melena, hematochezia | | Genitourinary | No dysuria, frequency, hematuria | | Musculoskeletal | No bone pain, arthralgia | | Neurologic | No weakness, paresthesias, seizures | | Dermatologic | No rash, pruritus | | Endocrine | Hyperglycemia controlled on insulin; no polyuria/polydipsia beyond baseline | --- ### Physical Examination - **General:** Well‑appearing, NAD, alert, oriented ×3, BMI 27 kg/m². - **Vital Signs:** BP 128/78 mmHg, HR 72 bpm, RR 16/min, SpO₂ 98% RA, Temp 36.8°C. - **HEENT:** Normocephalic, atraumatic, mucous membranes moist. - **Neck:** Supple, no cervical adenopathy. - **Cardiovascular:** Regular rate/rhythm, S₁S₂ normal, no murmurs. - **Respiratory:** Clear breath sounds bilaterally, no rales/wheezes, good air entry. - **Abdomen:** Soft, non‑distended, normoactive bowel sounds, no hepatosplenomegaly, no tenderness. - **Extremities:** No clubbing, cyanosis, edema.
