Lung Cancer Stages and Survival 2003-2009, All Races, Both Sexes Stage Distribution (%) 5-Year Relative Survival (%) 60 Percent 50 40 30 20 10 0 Localized (confined to primary Regional (spread to regional site) lymph nodes) Stage SEER Data, 2003-2009. Distant (cancer has metastasized) Unknown (unstaged) NSCLC: Breakdown by Subtype Squamous (30-35%) – Usually more centralized – More frequently associated with significant cough and hemoptysis Eaby-Sandy, 2011. NSCLC: Breakdown by Subtype Nonsquamous (65%) – Adenocarcinoma (40%) • Most common type of NSCLC • Most common type in nonsmokers – Large cell carcinoma (15%) – Mixed or NOS (10%) NOS = not otherwise specified. Eaby-Sandy, 2011. NSCLC: Why Does Histology Matter? In past, all NSCLC patients treated the same Data have shown that the use of certain agents in certain histologies results in improved survival and response rates Histology may predict the presence of biomarkers Safety parameters of certain treatments depend on histology NCCN, 2013. NSCLC: Breakdown of Biomarkers 1% 3% 3% Unknown KRAS 3% 2% EGFR 5% ALK RET 5% MET 33% PI3K BRAF 15% HER2 PDGFR VEGFR 25% FGFR1 AKT1 MEK1 ROS1 Hirsch, 2012. Molecular Abnormalities in NSCLC With Current Implications EGFR • Transmembrane receptor • Detectable in about 80-85% of patients • Level of expression varies widely • Mutations in this domain (10-15% of pts) result in activation of the tyrosine kinase domain with significantly better response to erlotinib or gefitinib • Mutations: highest incidence in never smokers, adenocarcinoma, women, and patients with Asian ethnicity KRAS • • • • EML4-ALK • Incidence of EML4-ALK translocation: 2-7% • Estimated prevalence of EML4-ALK in lung cancer: 6,000 pts/yr US; up to 40,000 pts/yr globally • Most EML4-ALK fusion events observed in lung adenocarcinoma specimens vs squamous or small cell histologies • EML4-ALK rarely coexists with EGFR, HER2, or KRAS mutations, indicating it is a distinct disease subtype 25% of North American population Associated with smoking and resistance to tyrosine kinase inhibitors KRAS mutations associated with shorter survival Therapy with drugs other than erlotinib should be considered first NCCN, 2013; Langer et al, 2010. Why Do Biomarkers Matter? PFS with standard chemotherapy regimens in NSCLC: – Pemetrexed/cisplatin: 5 months – Paclitaxel/carboplatin/bevacizumab: 6 months PFS with EGFR mutated NSCLC receiving EGFR targeted therapy: – Gefitinib: 9.5 months – Erlotinib: 9.7 months – Afatinib: 11.0 months PFS with ALK-positive NSCLC receiving ALK inhibitor: – Crizotinib: 9.7 months PFS = progression-free survival. Camidge et al, 2012; Yang, Shih et al, 2012; Rosell et al, 2012; Fukuoka et al, 2011; Scagliotti et al, 2008; Sandler et al, 2006. Patient Factors in Treatment Planning Patient ECOG PS – PS is a predictor of survival/tolerating chemotherapy – PS 0/1 patients tolerate chemotherapy best – PS 2 patients can potentially benefit, even from doublet chemotherapy; however, toxicity must be monitored closely Comorbidities – Diabetes, heart disease – Renal disease ECOG PS = Eastern Cooperative Oncology Group performance status. Rodriguez & Lilenbaum, 2008. Patient Factors in Treatment Planning Patient goals for treatment – Quality-of-life issue (eg, hair loss) – Advanced directives Demographics Social support – Involve social worker – Counseling services – Nutrition services Financial issues Evolving Supportive Care Paradigms Early palliative care leads to increase in OS in patients with metastatic NSCLC Increased quality of life, less depressive symptoms Improved understanding of diagnosis – 1/3 patients at diagnosis thought they had curable disease – Less likely to receive chemotherapy near end of life OS = overall survival. Temel et al, 2011; Temel et al, 2010. Case Study: First-Line Treatment Mrs. JF: History 68-year-old woman, presented 1 month ago with pain in her lower back Initial management with NSAIDs somewhat helpful; however, the pain persisted and an x-ray of the lower spine was ordered X-ray did not show bone abnormality but revealed a right lung mass at the right lung base Further imaging with PET/CT revealed a right lung mass, mediastinal lymphadenopathy, bone metastases in the lumbar spine, and liver metastases – X-rays are often negative NSAIDs = nonsteroidal antiinflammatory drugs; PET/CT = positron emission tomography/computed tomography. Mrs. JF: Diagnostic Evaluation Treating physician referred patient to pulmonologist for a bronchoscopy with biopsy – Mediastinal lymph node was positive for NSCLC, adenocarcinoma histology MRI scan of the brain negative for metastatic disease Baseline labs within normal limits Baseline PS 1 What factors important in treatment planning? MRI = magnetic resonance imaging. Mrs. JF: Treatment Considerations Bronchoscopy yielded core biopsy, able to perform KRAS, EGFR, ALK, and ROS testing. All were negative. Patient has a 45-pack-year smoking history, currently trying to quit Patient has hypertension (controlled with medication), hypercholesterolemia, and chronic obstructive pulmonary disease No significant weight loss, no hemoptysis Understands incurable, no advanced directive, would like to “fight” Mrs. JF: Treatment Selection Standard chemotherapy in biomarker-negative patient appropriate therapy Numerous options available for chemotherapy Platinum based chemotherapy appropriate given good PS Is hair loss an issue? Does she want to enroll in a clinical trial? NCCN, 2013. Mrs. JF: Treatment Selection Cisplatin versus carboplatin? In US, often use carboplatin in frontline therapy What drug to pair with carboplatin? Toxicity? – Pemetrexed – Paclitaxel – Docetaxel – nab-paclitaxel – Gemcitabine – Vinorelbine ECOG 1594: All Platinum Doublets Essentially Equal 1,207 patients, stage IIIB/IV (15/85%), PS 0-2 Median age 63; male/female: 64/36% R A N D O M I Z E Cisplatin Paclitaxel 75 mg/m2 D2 135 mg/m2/24h q3w Cisplatin Gemcitabine 100 mg/m2 D1 1 g/m2 D1,8,15 q4w Cisplatin Docetaxel 75 mg/m2 D1 75 mg/m2 D1 q3w Carboplatin Paclitaxel AUC=6 mg/mL/min D1 q3w 225 mg/m2/3h D1 AUC = area under the curve.

Sandler et al, 2006; Sandler et al, 2011. Median OS with Bevacizumab + PC was 12.3 months vs 10.3 months for PC alone (P=0.013) PointBreak Trial: Can Regimens Be Combined? Randomized, open-label, phase III superiority study conducted in US Pemetrexed 500 mg/m2; carboplatin AUC 6; bevacizumab 15 mg/kg Paclitaxel 200 mg/m2; carboplatin AUC 6; bevacizumab 15 mg/kg Inclusion: − No prior systemic therapy for lung cancer − PS 0/1 − Stage IIIB-IV nonsquamous NSCLC − Stable treated brain metastasized R 1:1 Exclusion: − Peripheral neuropathy ≥grade 1 − Uncontrolled pleural effusions q21d= every 21 days; PD = progressive disease.

Patel et al, 2012. Which Regimen to Choose for First-Line Treatment? Discuss toxicity profiles of different regimens Take histology into account Give patients autonomy to decide – Do they want treatment? – If so, which regimen’s toxicity profile is right for them? – Comorbidities? Diabetes? Coronary artery disease? Renal insufficiency? Maintenance Therapy If no disease progression after first-line chemotherapy, continue the chemotherapy and/or targeted agent? We know that in NSCLC continuing platinum chemotherapy past 4 to 6 cycles does not improve survival, just increases toxicity However, three drugs have shown improvement in PFS in the maintenance setting NCCN, 2013. E4599 Trial: Bevacizumab + PC Versus PC Alone in First-Line Nonsquamous NSCLC First-line treatment of patients with stage IIIB and malignant pleural effusion, stage IV, or recurrent NSCLC (N=878) Stratified by • Disease stage • Degree of weight loss • Prior radiotherapy • Measurable disease q3w = every 3 weeks; IV = intravenously.
