4 Lung Cancer Facts and Figures Most common cause of cancer-related mortality in US Accounts for more deaths than breast, prostate, and colorectal cancers combined Histologically and molecularly a very heterogeneous disease Unfavorable stage distribution at the time of diagnosis (screening not routinely practiced) 25,000 to 30,000 never-smoking Americans will develop lung cancer this year (more common than esophageal, gastric, ovarian, testicular, Hodgkin, myeloma, CML) Historically shrouded by therapeutic nihilism American Cancer Society. Facts & Figures

5 First-Line Considerations How well established is the histologic diagnosis? Is tissue available for “special” studies? – EGFR mutation, EML4-ALK, others Optimal chemotherapy Role of targeted therapies –Antiangiogenic –Anti-EGFR Genotypically driven therapy Treatment-related side effects and toxicities M. Socinski, MD.

6 Molecular Profiling and Therapeutic Decision Making for Advanced NSCLC NCCN 1 –Test for EGFR mutations and ALK in lung adenocarcinoma, large-cell lung cancer, NSCLC NOS as determinants for treatment selection ASCO 2 –Test for EGFR mutations in patients with advanced NSCLC who are being considered for first-line treatment with an EGFR TKI CAP/IASLC/AMP 3 –Test for EGFR mutation and ALK fusion (+ others?) in NSCLC adenocarcinoma patients at the time of diagnosis and after a targeted therapy intervention (to assess for tumor evolution in the molecular profile) 1.

7 Mutations in NSCLC Association between EGFR mutations and sensitivity to TKIs –Exon 19 deletion –Exon 21 (L858R) –Exon 18 (G719X) Exon 20 insertion may predict resistance to TKIs EGFR and KRAS mutations are mutually exclusive in NSCLC 10% of Western and 50% of Asian NSCLC patients have mutation of EGFR KRAS mutation associated with primary resistance to TKIs Presented by: Bruce E. Johnson, MD. NCCN. Clinical Practice Guidelines in Oncology. NSCLC V Distribution of Mutations in 733 Genotyped

8 ALK Translocations in NSCLC ALK: anaplastic lymphoma kinase Gene rearrangements: –Chromosome 2 inversion –Fusion with EML4 gene Abnormal expression and activation Rearrangement occurs in 2% to 5% of NSCLC Occurs independently of EGFR or KRAS mutations Predominantly in: –Young patients (50 years or younger) –Never- or former-smokers with adenocarcinoma Gridelli C, et al.
