Lung cancer is the leading cause of cancer death worldwide, accounting for more deaths than breast, prostate and colon cancer combined. While treatment decisions are determined primarily by stage, therapeutically non small cell lung cancer (NSCLC) has traditionally been treated as a single disease. ⋯ Microarray and genomic sequencing efforts have provided unparalleled insight into the genomes of lung cancer subtypes, specifically adenocarcinoma (AC) and squamous cell carcinoma (SqCC), revealing subtype specific genomic alterations and molecular subtypes as well as differences in cell signaling pathways. In this review, we discuss the recurrent genomic alterations characteristic of AC and SqCC (including molecular subtypes), their therapeutic implications and emerging clinical practices aimed at tailoring treatments based on a tumor's molecular alterations with the hope of improving patient response and survival.

Review Meta Analysis
Is there an oligometastatic state in non-small cell lung cancer? A systematic review of the literature.
Long-term survival has been observed in patients with oligometastatic non-small cell lung cancer (NSCLC) treated with locally ablative therapies to all sites of metastatic disease. We performed a systematic review of the evidence for the oligometastatic state in NSCLC. ⋯ Survival outcomes for patients with oligometastatic NSCLC are highly variable, and half of patients progress within approximately 12 months; however, long-term survivors do exist. Definitive treatment of the primary lung tumor and low-burden thoracic tumors are strongly associated with improved long-term survival. The only randomized data to guide management of oligometastatic NSCLC pertains to patients with brain metastases. For other oligometastatic NSCLC patients, randomized trials are needed, and we propose that these prognostic factors be utilized to guide clinical decision making and design of clinical trials.
