No Difference in Chemotherapy Benefits for Young Patients with Stage II and III Colon Cancer Compared to Those Fifty and Older

Young patients with stage II or III colon cancer get equal benefit from chemotherapy as older patients, and they have similar side effects. Five years after treatment, 67 percent of patients under the age of fifty hadn’t had their cancer spread beyond the colon (recurrence-free interval), the same percentage that applied to patients who were fifty…  Read More

How likely is it that an individual colon cancer will return? Stage II colon cancer patients have a tough time knowing how likely it is that their cancer will recur and making a decision about having chemotherapy after surgery. A test is now on the market that can help with that decision.  OncoType DX® Colon Assay…  Read More

ASCO Research Highlights: Molecular Markers in Stage II and III Colon Cancer

Several studies presented at ASCO looked a biomarkers that might predict cancer recurrence or patient survival in stage II and III colon cancer and whether patients could be chosen to receive chemotherapy based on those markers.  Of special interest was the hypothesis offered by two researchers from the PETACC-3 clinical trial that stage II and stage…  Read More

Gene Test Shows Risk of Recurrence of Stage II Colon Cancer

The first genomic test to predict whether or not stage II colon cancer will recur has been developed and validated in a large number of tumor tissue samples from patients in the United States and the United Kingdom.  The 12 gene assay can reliably predict whether an individual patient has a low, intermediate, or high risk…  Read More

Some Stage II Colon and Rectal Cancers can be More Dangerous than Stage III

Advance Abstracts from ASCO 2008 How far a colon or rectal cancer penetrates through the wall of the bowel may be more important in deciding survival risks than current staging that focuses on positive lymph nodes. Five year survival statistics for a large number of rectal and cancer patients verified an earlier study that found some…  Read More
