2 Initial Evaluation/Intervention: 1. Pathology Review 2. History and Physical (including performance status and weight loss evaluation) 3. CBC, platelets, chemistry profile 4. CT chest, upper abdomen including adrenals 5. PET scan when clinically indicated 6. Brain MRI for stage II and above 7. Bronchoscopy 8. EBUS when clinically indicated 9. Mediastinoscopy when clinically indicated 10. Smoking cessation counseling Pathologic Review: For classification of lung cancer type, extent of invasion, involvement status or surgical margins. Determination of abnormalities which predict for sensitivity vs. resistance to EGFR-TKI s (EGFR mutations exon 19 deletion, exon 21 mutation and exon 18, KRAS mutation) Tumor classification system used is defined by WHO Immunohistochemistry: TTF-1: distinguishes primary from metastatic adenocarcinoma; majority of primary lung cancer is positive for TTF-1; metastatic adenocarcinoma is almost always negative for TTF-1 Pulmonary adenocarcinoma usually is CK7+/CK20-; metastatic adenocarcinoma of colorectal origin usually is CK7-/CK20+. CDX-2 is sensitive and specific for primary GI malignancies. Chromogranin and Synaptophysin are usually positive in neuroendocrine tumors including all carcinoid, but are negative in 25% of small cell lung cancer cases

5 1. Resectable/Early Stage (TNM stage I, II, some IIIA) A. Surgical candidate: Surgery Lobectomy is preferred over segmentectomy or wedge resection. Lung sparing anatomic resection or sleeve lobectomy preferred over pneumonectomy B. Not a surgical candidate : SBRT for peripheral lesions C. Adjuvant Chemotherapy (T2,N0-high risk*; T3,N0; T1-T3,N1-N2) *High risk: poorly differentiated tumors, vascular invasion, wedge resection, minimal margins, tumors >4cm, visceral pleural involvement, unknown nodal status) D. Positive margins: Re-resection or chemo-radiotherapy

6 2. Superior sulcus tumor (T3-T4 N0 or N1): Neo-adjuvant chemo-radiotherapy followed by surgery preferred treatment or Definitive chemo-radiotherapy 3. Single N2 lymph node <3cm can be approached with Neo-adjuvant chemotherapy or chemo-radiotherapy followed by evaluation for surgery
