Molecular Staging Of Colorectal Cancer: K-Ras Mutation Analysis Of Lymph Nodes Upstages Dukes’ B2 Patients, Jennifer S. Thebo
The successful treatment of colorectal cancer depends upon the ability of staging systems to identify patients who are at risk for recurrence. The currently used systems fail in a significant number of patients. Multiple attempts have been made to improve upon these systems in order to provide better treatment for at-risk patients.
A variety of oncogenes and tumor suppressor genes have been implicated in colorectal cancer. Mutations in one of these, K-ras, occur in 40-60% of colorectal carcinomas. However, the relationship between specific mutations and clinical outcome is unclear.
The purpose of this study was to determine whether or not ...
