BACKGROUND: In addition to identifying and eradicating premalignant lesions, and detecting early cancer before the development of life-threatening consequences, new concepts and technological advances have stimulated a hightened interest in the secondary prevention of colorectal cancer.
METHODS: People whose first degree relatives have had colorectal cancer are considered to run a higher risk of developing colorectal carcinoma. A screening program was carried out for 358 first degree relatives of colorectal cancer patients using colonoscopic screening.
RESULTS: The mean age of these first degree relatives was 44 years, ranging from 13 to 78 years. Two hundred and eleven (58.9%) of them were asymptomatic. Totally 73 polyps were detected in 53 subjects (14.9%). Two cancer lesions were identified. Thirty polyps (41.1%) measured between 0.5 cm and 2.0 cm. The polyps were mostly located in the rectum and sigmoid colon (63%). One polyp was found in a subject below 30 years of age. Over the age of 30, the incidence of polyp increased dramatically.
CONCLUSIONS: Our results confirmed that the screening program for the first degree relatives of patients with colorectal cancer is worthwhile. The program would have a more significant impact if the screening could start from subjects around the age of 30.
