Abstract | OBJECTIVE: METHODS: We analyzed 277 stool samples from cancer patients with diarrhea between Sep 2010 and Dec 2011 in our hospital. Stool C. difficile toxin A/B test, stool culture for C. difficile and routine stool examination were performed. In addition, the risk factors for CDAD were investigated in a set of 41 C. difficile toxin-positive cancer patients and 82 matched C. difficile toxin-negative controls by univariate analysis and multivariate analysis. RESULTS: Out of a total of 277 cancer patients with diarrhea, 41 (14.8%) were C. difficile toxin-positive. Among these 41 cases, 11 (26.8%, 11/41) were C. difficile culture-positive. Univariate analysis showed that antibiotics use (P = 0.853), proton pump inhibitor use (P = 0.718), hypoproteinemia (P = 0.139) and white blood cell count (P = 0.454) did not appear to be associated with acquisition of CDAD in cancer patients. However, receiving chemotherapy (P = 0.023), receiving radiotherapy (P = 0.003), a positive fecal occult blood test result (P = 0.005) and the presence of fecal leukocytes (P = 0.007) showed close association with acquisition of CDAD in cancer patients. Multivariate analysis showed that receiving chemotherapy (OR, 8.308; 95% CI, 1.997-34.572; P = 0.004) and a positive result of fecal occult blood test (OR, 8.475; 95% CI, 1.463-49.109; P = 0.017) were independent risk factors for acquisition of CDAD among cancer patients. CONCLUSIONS: Our results support that receiving chemotherapy and a positive fecal occult blood test result are independent risk factors for acquisition of CDAD among cancer patients. Cancer patients who are at high-risk for CDAD should take stool C. difficile toxin A/B test and stool culture for C. difficile regularly and prevention of CDAD.
