Curcumin in Preventing Colorectal Cancer in Patients Undergoing Colorectal Endoscopy or Colorectal Surgery
RATIONALE: Chemoprevention is the use of certain drugs to keep cancer from forming. The use of curcumin may prevent or treat colorectal cancer.
PURPOSE: This phase I trial is studying the side effects of curcumin in preventing colorectal cancer in patients undergoing colorectal endoscopy or colorectal surgery.
- To determine levels of curcumin and its metabolites in normal colorectal tissue in patients undergoing colorectal endoscopy or colorectal cancer surgery following a 14-day course of curcumin.
- To assess the practicality, acceptability, and safety of administering 5 capsules of curcumin daily for 14 days.
- To check the presence of curcumin and its metabolites in peripheral blood and urine.
OUTLINE: Patients receive oral curcumin once daily for 14-28 days. Patients then undergo colorectal endoscopy or resection.
Normal colorectal tissue samples are collected via biopsy for curcumin assay after the last dose of curcumin. Patients also undergo blood and urine sample collection at baseline and after the last dose of curcumin for pharmacokinetic analysis by high performance liquid chromatography.
After completion of study treatment, patients are followed up at 14 days.
Primary Purpose: Prevention
curcumin, high performance liquid chromatography, laboratory biomarker analysis, pharmacological study, diagnostic endoscopic procedure, therapeutic conventional surgery

Medical and Biotech [MESH] Definitions
Chromatography, High Pressure Liquid
Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed.
Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.
A method of separation of two or more substances by repeated distribution between two immiscible liquid phases that move past each other in opposite directions. It is a form of liquid-liquid chromatography. (Stedman, 25th ed)
Chromatographic techniques in which the mobile phase is a liquid.
Solid Phase Extraction
An extraction method that separates analytes using a solid phase and a liquid phase. It is used for preparative sample cleanup before analysis by CHROMATOGRAPHY and other analytical methods.
