Effects of LKB1 Mutation and mTOR Inhibition on IGFR1 Pathway in NSCLC
LKB1 is a serine/threonine kinase that has been found to be mutated in approximately 20% to 30% of patients with non–small cell lung cancer (NSCLC). LKB1 acts as a tumor suppressor by activating AMPK, and loss of LKB1 by point mutation or deletion suppresses AMPK, leading to increased mTOR...
PD-1 Blockade Increases Transferred T-cell Migration to Tumors
One reason that adoptive cell transfer has met with limited clinical success is that approaches based on this strategy have not fully taken into account the role of the tumor microenvironment as a limiting factor in immunotherapy. Recently reported studies by Peng and colleagues1 from The...

Trastuzumab Emtansine Improves Survival vs Capecitabine plus Lapatinib in Second-line HER2-positive Breast Cancer
Trastuzumab emtansine (T-DM1) is an antibody-drug conjugate composed of trastuzumab bound to the cytotoxic microtubule inhibitor emtansine (DM1, derivative of maytansine) by a stable linker. Trastuzumab targets the conjugate to HER2 receptors, and the linker releases the cytotoxic agent when the...
Expert Point of View: John L. Marshall, MD
The pendulum continues to swing in the treatment of stage II and III colon cancer. Not 5 years ago, our party line was that essentially all patients should receive 6 months of adjuvant FOLFOX (leucovorin, fluorouracil [5-FU], oxaliplatin): patients with stage II or III disease, whether rectal or...
