Despite complete surgical resection of stage I-III lung cancer tumor recurrence develops in up to 50% of patients.1 After recurrence, survival is poor, with five-year rates as low as 30% even with adjuvant cytotoxic chemotherapy for high-risk populations.1 The current rationale for recommending adjuvant therapy relies solely on TNM (tumor, node, and metastasis) classification, and more recently PD-L1 expression, and is largely agnostic to clinicopathologic and tumor genomic factors. As a result, survival benefits are modest at best when using the TNM model to select patients for adjuvant therapy. With the recent explosion of next-generation sequencing and robust genomic data, our lab is rigorously investigating associations between tumor genomics and recurrence and disease-free survival (DFS) in people with early-stage lung adenocarcinoma (LUAD). In addition to a gene-centric approach, we have also performed oncogenic pathway analyses to ascertain if these analyses can supplement existing TNM indicators for prognosis and prediction of recurrence2. In addition, using our large genomically annotated LUAD database we were able to demonstrate unique differences in tumor genomics and mutational signatures across LUAD histologic subtypes3. In addition, we identified KRAS G12C mutation as significant negative prognostic variable following completely resected of early stage LUAD4. We have also focused on the prognostic abilities of tumor mutation burden (TMB) as well as the fraction of genome (FGA) - a measure of the percentage of the genome affected by gains or losses in copy number - and their association with LUAD recurrence. We recently developed PRecur, a novel computational machine-learning model that integrates genomic and clinicopathologic factors, to predict DFS in our MSK LUAD cohort (see figure below) and found that incorporation of both genomic and selected high-risk clinicopathologic variables is superior to TNM classification in predicting recurrence following surgery5. We believe that continued investigation of tumor genomics in early-stage lung cancer has the possibility of moving the field toward use of this information to guide therapeutic decisions6. Currently we are actively examining the LUAD genomics associated with organotropism as well as genomic differences between primary tumors that do and do not develop metastatic disease7. We actively collaborate with the Marie-Josée and Henry R. Kravis Center for Molecular Oncology at MSK, the Nikoulaus Schultz Laboratory, the Marcin Imielinski Laboratory, as well use MSK OncoKB, MSK-IMPACT™, and related bioinformatics platforms.
