Aspirin in Treating Patients With Colorectal Cancer That Has Been Surgically Removed

2014-08-27 03:59:07 | BioPortfolio

Summary

RATIONALE: Chemoprevention therapy is the use of certain drugs to try to prevent the development or recurrence of cancer. The use of aspirin may be an effective way to prevent the recurrence of polyps in colorectal cancer.

PURPOSE: Randomized phase III trial to study the effectiveness of aspirin in treating patients who have stage I, stage II, or stage III colorectal cancer that has been surgically removed.

Description

OBJECTIVES: I. Determine whether aspirin administered at a dose of 325 mg/day will decrease the number and size of new adenomas in patients with Dukes' A/B1/B2/C colorectal cancer who have undergone curative surgical resection. II. Assess whether this dose of aspirin will increase disease-free survival in these patients.

OUTLINE: Randomized, double-blind study. Arm I: Chemoprevention. Enteric-coated Aspirin, ASA, NSC-27223. Arm II: Control. Placebo, PLCB.

PROJECTED ACCRUAL: Approximately 900 patients will be randomized over 4 years.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the COLON or the RECTUM or both. Risk factors for colorectal cancer include chronic ULCERATIVE COLITIS; FAMILIAL POLYPOSIS COLI; exposure to ASBESTOS; and irradiation of the CERVIX UTERI.

Tumor suppressor genes located in the 5q21 region on the long arm of human chromosome 5. The mutation of these genes is associated with the formation of colorectal cancer (MCC stands for mutated in colorectal cancer).

Tumor suppressor genes located in the 18q21-qter region of human chromosome 18. The absence of these genes is associated with the formation of colorectal cancer (DCC stands for deleted in colorectal cancer). The products of these genes show significant homology to neural cell adhesion molecules and other related cell surface glycoproteins.

A group of autosomal-dominant inherited diseases in which COLON CANCER arises in discrete adenomas. Unlike FAMILIAL POLYPOSIS COLI with hundreds of polyps, hereditary nonpolyposis colorectal neoplasms occur much later, in the fourth and fifth decades. HNPCC has been associated with germline mutations in mismatch repair (MMR) genes. It has been subdivided into Lynch syndrome I or site-specific colonic cancer, and LYNCH SYNDROME II which includes extracolonic cancer.

Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.
