- W1991738197 abstract "Background: Chronic renal failure was known as a risk of malignancy. However, few studies on the relationship between chronic renal failure and colonic neoplasia have been reported. In this study, we investigated the prevalence and characteristics of colorectal neoplasia in patients with chronic renal failure on regular hemodialysis treatment. Methods: We conducted a case-control study. Patients with hemodialysis who received screening colonoscopy at Okayama University hospital and Shigei Medical Research hospital from August 2003 to October 2004 were prospectively enrolled. As control subjects, patients who were asymptomatic and underwent first-time complete colonoscopy at the same hospitals during the same period were also enrolled. Results: Thirty-five hemodialysis patients (average age of 67 (41-86) years) and 215 controls (average age of 61 (41-89) years) were enrolled. There were no significant differences in age and gender distributions between the two groups. The prevalence of colorectal neoplasia in hemodialysis patients (26/35, 74%) was significantly higher than that in controls (105/215, 49%) (odds ratio, 3.03; 95% confidence interval [CI], 1.35-6.76). Hemodialysis patients showed high prevalence of multiple polyps (single polyp in 27% and multiple polyps in 73%) compared with control patients (single polyp in 65% and multiple polyps in 35%) (P < 0.05). Moreover, multiple polyps found in hemodialysis patients were likely to be located at both left (descending colon, sigmoid colon, and rectum) and right (transverse colon, ascending colon, and cecum) colon (left only: right only: both = 1:1:2.4) compared to polyps found in control subjects (left only: right only: both = 2.5:1.5:1) (P < 0.05). In addition, hemodialysis patients had more advanced neoplasia (adenoma ±10 mm, adenoma with villous component, adenoma with high grade dysplasia, and cancer) than control subjects (odds ratio, 2.26; 95% CI, 1.08-4.09). Conclusions: Our results indicated that the status of chronic renal failure is strongly associated with the risk of colorectal neoplasia. Therefore, total colonoscopy should be recommended as screening test for colorectal neoplasia in patients with chronic renal failure, especially those on hemodialysis treatment.
