Colonoscopic screening for first degree relatives of patients with colorectal cancer



Colonoscopic screening for first degree relatives of patients with colorectal cancer



Zhonghua Yi Xue Za Zhi 54(3): 166-169



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. 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. 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. 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.
