Available data suggest that patients with stage II/III colon cancer receive similar benefit from intravenous fluorouracil (5-FU) adjuvant therapy regardless of age. Combination regimens and oral fluoropyrimidine therapy are now standard treatments in this setting. Nadine J. McCleary, MD, MPH, and...
Genomic heterogeneity within tumors and among lesions varies widely, and “discordance among lesions could lead to the selection of the ‘incorrect’ targeted inhibitor,” according to David B. Solit, MD, of Memorial Sloan-Kettering Cancer Center, who spoke at the ASCO/American...
A study from the University of Colorado Cancer Center shows that the ALK and ROS1 gene rearrangements known to drive subsets of lung cancer are also present in some colorectal cancers. Results imply that drugs used to target ALK and ROS1 in lung cancer may also have applications in this subset of...
First-line cetuximab (Erbitux) plus FOLFIRI chemotherapy (leucovorin, fluorouracil [5-FU], irinotecan) offered a roughly 4-month survival advantage over bevacizumab (Avastin) plus FOLFIRI for patients with KRAS wild-type metastatic colorectal cancer in the German phase III clinical trial FIRE-3. A ...

New results from a clinical trial conducted in Shanghai, China, indicate that adding cetuximab (Erbitux) to standard chemotherapy enables some patients with otherwise inoperable liver metastases due to colorectal cancer have their metastases surgically removed. Such surgery can be curative, and is...
Researchers at Roswell Park Cancer Institute (RPCI) have found that a new formulation of a promising anticancer agent, the small chemical molecule FL118, is even more effective in controlling two types of cancer than a version reported in PLOS ONE 6 months earlier proved to be. Additional evidence...
