Advanced colorectal cancer patients with BRAF mutations have markedly worse prognosis than non-mutant patients, according to a large analysis. Post-progression survival in particular is worse among BRAF-mutant patients.
Patients with metastatic colorectal cancer who engaged in more hours of physical activity at the time of their diagnosis had improvements in both progression-free and overall survival compared with patients who had less physical activity.
Non-aspirin NSAIDs are more effective than other options for colorectal chemoprevention in individuals with previous colorectal neoplasia, according to a new meta-analysis. Low-dose aspirin, however, is a safer option, and offers the best risk-benefit profile.
A 44-year-old patient with a history of stage IIB colorectal cancer at the hepatic flexure, invading the duodenum and pancreas, was initially diagnosed in September 2005 and received modified Whipple surgery and 8 cycles of adjuvant chemotherapy with capecitabine and oxaliplatin every 3 weeks.
In the United States, approximately 20% of patients with colorectal cancer present with distant metastasis at diagnosis.

In this video, Dung T. Le, MD, discusses a phase II study that found that mismatch repair–deficient colorectal tumors were highly responsive to checkpoint blockade with the anti–PD-1 drug pembrolizumab.
