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.

Condition Intervention Phase
Colorectal Cancer
Dietary Supplement: curcumin
Other: high performance liquid chromatography
Other: laboratory biomarker analysis
Other: pharmacological study
Procedure: diagnostic endoscopic procedure
Procedure: therapeutic conventional surgery
Phase 1

Study Type: Interventional
Study Design: Primary Purpose: Prevention
Official Title: A Pilot Study of Administration of Curcumin to Determine Colonic Curcumin Tissue Levels in Patients Awaiting Colorectal Endoscopy or Patients With Colorectal Cancer Awaiting Resection

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Concentration of curcumin in colorectal tissue after treatment [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Tolerability and compliance [ Designated as safety issue: No ]
  • Presence of curcumin and its metabolites in peripheral blood and urine [ Designated as safety issue: No ]

Estimated Enrollment: 30
Study Start Date: July 2009
Estimated Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Detailed Description:



  • 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.
