RATIONALE: Collecting and storing samples of blood and tissue from patients undergoing colonoscopy to study in the laboratory may help doctors learn more about colon cancer and identify biomarkers related to colon cancer in the future.
PURPOSE: This laboratory study is collecting blood and tissue samples for future colon cancer biomarker studies in patients undergoing colonoscopy.
- Collect blood and tissue samples (including polyps, abnormal growths, cancer, and normal tissue) from patients undergoing colonoscopy.
OUTLINE: Patients undergo blood and tissue sample collection during colonoscopy. Samples are stored for future biomarker proteomic profiling.

RATIONALE: Studying samples of tissue, blood, urine, stool, and other biological fluids from patients with cancer and from healthy participants may help doctors identify and learn more abo...
RATIONALE: Collecting and storing samples of tissue, blood, and other body fluids to test in the laboratory and gathering information about health and lifestyle from participants may help ...
The purpose of this study is to compare the additional diagnostic yield obtained by performing NaviAid™ G-Eye procedure vs. the diagnostic yield obtained by performing standard colonosco...
Colorectal cancer (CRC) is the third most common cancer and second leading cause of cancer deaths in western countries. Colonoscopy is a preferred colorectal screening modality since it h...
RATIONALE: Diagnostic procedures, such as ultrasound, x-ray, colonoscopy, CT scan, and CEA assessment, may help monitor a patient's response to surgery. It is not yet known which follow-up...
A fecal immunochemical test (FIT) is often repeated annually, even after a recent colonoscopy. However, there are no published data on the proper approach to FIT-positive patients after a recent colon...
We identified patients without medical record evidence of up-to-date colorectal cancer (CRC) screening and sent an invitation letter to self-schedule a colonoscopy without requiring prior primary care...
According to international guidelines, patients presenting with acute diverticulitis are offered lower endoscopy to rule out colorectal cancer. This practice is based on weak evidence. Recent studies ...
Colorectal cancer (CRC) screening is capable of reducing CRC-related morbidity and mortality. Colonoscopy is the reference standard to detect CRC, also providing the opportunity to detect and resect i...
Colonoscopy adherence among populations at high risk for colorectal cancer (CRC) is crucial for the early diagnosis and treatment of CRC, but the adherence rate has been found to be poor. A short mess...
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.
Colon or Colorectal cancer is the growth of malignant polyps on the colon, bowel, anus and rectum. Growths in these locations can be benign, and removed by colonoscopy, but they have a risk of becoming malignant. About 10 per cent of bowel cancer...
