Gastrointestinal Cancer

A set of genes that are more likely to be mutated in African-Americans vs Caucasians with colorectal cancer appears to increase the risk of metastases and relapse in mutant versions.

In this interview we discuss the GeneFx Colon test (or the ColDx assay), which can helpful identify patients with low- or high-risk stage II colon cancer.

A gene expression microarray-based assay was able to successfully identify patients with stage II colon cancer who are at high risk for recurrence.

A study found that fusobacteria, commonly found in the mouth, can enrich colorectal cancer cells, in a process mediated by the Fap2 protein.

These guidelines review the use of radiation, chemotherapy, and surgery in borderline and unresectable pancreas cancer. Radiation technique, dose, and targets were evaluated, as was the recommended chemotherapy, administered either alone or concurrently with radiation. This report will aid clinicians in determining guidelines for the optimal treatment of borderline and unresectable pancreatic cancer.

Here we review the evidence supporting current approaches to resectable gastric cancer, including discussion of the optimal extent of surgery and lymphadenectomy, adjuvant chemotherapy, postoperative chemotherapy with chemoradiation, and perioperative chemotherapy.

Current methods of treatment still have a small impact on the survival of patients with localized disease. Improved understanding of the underlying mutations seen in gastric cancer might suggest alternative treatments and ways to better select patients.
