Single Nucleotide Polymorphisms Predict Severe Toxicity of Adjuvant Therapy in Colorectal Cancer
Oxaliplatin/fluoropyrimidine–based adjuvant therapy is of benefit in patients with resected stage II/III colon cancer, but the ability to predict risk of toxicity could improve care by permitting individualization of treatment. Ana Custodio, MD, and colleagues from GEMCAD (Grupo Español...
Two Single Nucleotide Polymorphisms Associated with Risk for Paclitaxel-related Peripheral Neuropathy
Peripheral neuropathy is the most common severe toxicity in patients receiving paclitaxel, and mutations in genes affecting drug metabolism, distribution, and elimination are likely to modulate risk for such neurotoxicity.

Alterations in PTEN Insufficient to Predict Sensitivity to Drugs Targeting PI3K/mTOR Pathway
PTEN acts as a tumor-suppressor gene through the action of its phosphatase protein product, which participates in regulation of the cell cycle to prevent too-rapid cell growth and division. Loss of PTEN function has been shown to increase PI3K/mTOR signaling, and preclinical data suggest that PTEN...

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...
