Patients with colon cancer have learned over the last two years that we have now a genetic marker which can predict efficacy of antibodies against EGFR which are used in patients with metastatic colon cancer.

We have learned that tumors with mutations in KRAS will not benefit from this treatment. All patients should be tested for KRAS mutation if they have advanced or metastatic disease.

However patients who have mutations of the KRAS gene don’t do worse than patients with wild type. The only difference is that the drugs which target EGFR will not work. Read the rest of this entry »

Patients with liver tumors, including those that have spread from colorectal cancer, can enroll in a clinical trial at the National Institutes of Health Clinical Center in Bethesda.

The trial will test the effectiveness of infusing the drug melphalan through the artery that feeds the liver.

Colorectal cancer patients with liver metastases are eligible for the trial if they have already had chemotherapy including irinotecan or oxaliplatin.  Limited cancer outside of the liver is acceptable if the most serious problem is within the liver itself. Read the rest of this entry »

• The Colorectal Cancer Association of Canada is sponsoring a contest for print and video ads that raise awareness of colorectal cancer.
• Clinical trials at the NIH Clinical Center in Bethesda, MD are an option for cutting-edge treatment at no cost.
• When co-pays are raised for Medicare, the elderly make fewer outpatient visits but are hospitalized more often and stay in the hospital longer.

It doesn’t help patients to add Erbitux to FOLFOX chemotherapy after surgery for stage III colon cancer a data monitoring committee for a clinical trial testing the new treatment has decided.

Because the analysis showed that patients were not benefiting from adding Erbitux to FOLFOX chemotherapy, the trial has been closed according to a news release from the National Cancer Institute. Read the rest of this entry »

At the ECCO/ESMO  meeting in Berlin the data on a large phase III clinical trial from the United Kingdom (COIN) was presented. It was a trial comparing FOLFOX or XELOX in combination with Erbitux.

It is important to know that in the UK Avastin is not approved, and Erbitux was only recently approved in patients with organ limited disease based on the chance of curative resections in patients initially deemed not to be resectable. However it is difficult to judge what the COIN results mean. The response rates in the patients with wild-type KRAS was significantly increased to 64%, so far so good. The problem is that the time to tumor progression and overall survival was not improved in patients with wild-type KRAS and Erbitux therapies. Read the rest of this entry »
