Colorectal cancer (CRC) is the second common cause of death in the Western world, and is very increasing in Japan. Fecal occult blood test (FOBT) is used routinely for CRC screening, which has been shown to reduce the incidence, morbidity, and mortality of CRC. However, there is a need to develop a novel method to improve sensitivity. The investigators reported that Fecal COX-2 assay, one of fecal RNA test, is potentially useful for colorectal cancer screening (Gastroenterology 127; 422-427, 2004). So the investigators planed to compare fecal RNA test with FOBT for detecting colorectal cancer and adenoma.

Colorectal cancer is one of the most common cancers globally. A large portion of colorectal cancer patients who are treated with conventional chemotherapy eventually develop local recurrence or metast...
Colorectal carcinoma is the third most common cancer worldwide. Approximately 20% of patients with colorectal cancer will have metastatic disease at the time of initial diagnosis, and approximately 30...

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.
