NCT00030563
RATIONALE: Radiofrequency ablation uses high-frequency electric current to kill tumor cells. Combining radiofrequency ablation with surgery may kill more tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving a chemotherapy drug after surgery and radiofrequency ablation may kill any remaining tumor cells. PURPOSE: Phase II trial to determine the effectiveness of surgery with or without radiofrequency ablation followed by irinotecan in treating patients who have colorectal cancer that is metastatic to the liver.
NCT00153816
Extensive experimental and observational data suggest that intake of calcium and of vitamin D exert protective effects on colorectal neoplasia. Building on their previous work, the investigators will investigate the chemopreventive effect of vitamin D in the large bowel, to study whether calcium with vitamin D is more effective than calcium alone, and to confirm their positive finding regarding calcium. The goal of this study is the development of chemopreventive combinations that will reduce risk of colorectal neoplasia sufficiently to permit the lengthening of surveillance intervals in most patients and to clarify important issues regarding the mechanisms of colorectal carcinogenesis and chemoprevention.
