Trial seeks 'genetic fingerprint' for predicting drug effectiveness
Date:10/3/2007

etic factors that must be addressed individually.

The UC-led national team is looking for about 70 patients across the United States with up to stage-3 gastric cancer to participate in the trial.

Prior to surgery, all study participants will have a biopsy to set baseline standards for genetic testing to determine which patients have a complete response to the multi-treatment therapy. Participants will receive daily doses of the platinum-containing drug oxaliplatin (ox-AL-ih-plah-tin, marketed as Eloxatin) for six to eight weeks.

Approved by the Food and Drug Administration, oxaliplatin is currently used to treat advanced colorectal cancer. Studies have shown the drug has fewer toxicity complications compared with other therapies.

After six weeks of chemotherapy, the patient will get five consecutive days of three-dimensional, external-beam radiation therapy. Patients will be reevaluated two to three weeks after radiation to determine if they are eligible for surgery. Those who are suitable will have another tissue biopsy after surgery.

Researchers will compare pre- and post-surgery tissue samples to obtain the genetic data necessary to establish associations between molecular markers and drug resistance, with the goal of reducing toxicity associated with chemotherapeutic agents and improving patient survival.
