A questionnaire study was done in order to clarify the risk ratios on the mortality of malignancy and the characteristics of malignancies in dialysis patients. The risk ratios were 4.2 times in males and 7.5 times in females greater than those among the age adjusted general population respectively. The average interval from the first dialysis to the clinical onset of malignant disease was 12 months. About a half of the patients died within 3 months. Frequencies of death in colon cancer, especially rectum, uterus and liver were higher in dialysis patients. Dialysis patients died of malignancies belonged to the older group of the dialysis patient population, however they were younger comparing with those died of malignancies in the general population.

We previously reported that peritoneal dialysis (PD)-associated peritonitis is a major cause of PD catheter removal. Another major cause is disease of the gastrointestinal tract, including neoplasm and perforation. In the present study, we reviewed the records of patients who underwent catheter removal at our hospital for reasons other than peritoneal infection--and for gastrointestinal disease in particular. Data were collected from the records of patients who received continuous ambulatory PD (CAPD) therapy between 2004 and 2010 at the Department of Nephrology, Saitama Medical University. Mean duration of CAPD was 6.2 +/- 4.7 years, and mean age at onset was 64.5 +/- 9.6 years. During the investigation period, catheters were removed from 13 patients (4 men, 9 women) because of gastrointestinal disease: gastric cancer in 3 cases, colon cancer in 3 cases, perforation of the lower gastrointestinal tract in 3 cases, and other reasons in 4 cases. Examination of pathology specimens obtained from 6 patients-including 1 in whom contrast-enhanced computed tomography indicated the presence of encapsulating peritoneal sclerosis (EPS)-revealed mild fibrosis in the subserous layer. No patient died of infection after a surgical procedure. Moreover, throughout the observation period, no patient developed new EPS or postoperative ileus. The present study suggests that CAPD itself seems to be free of untoward effects during the postoperative course in these patients.

A laparoscopic approach represents an effective alternative to open surgery in patients undergoing peritoneal dialysis (PD). In these patients, conventional thinking provides for removal of the peritoneal catheter during left colon resections because of higher risk of patient contamination and peritonitis. The present paper describes 3 cases of laparoscopic left hemicolectomy for colon cancer performed in PD patients without complications and without peritoneal catheter removal, leading to subsequent early PD resumption.Three normotype PD patients affected by early-stage sigmoid colon adenocarcinoma (T1-T2, M0, N0) underwent integrated surgical and nephrological management to reduce peritoneum stress, infective risk and postoperative complications. The day before surgery, patients were shifted to isovolumetric hemodialysis through tunneled central venous catheter. All patients underwent laparoscopic left hemicolectomy without Tenckhoff catheter removal. The postoperative period was uneventful, with concomitant antibiotic prophylaxis until the fifth day after surgery. Flushing of the PD catheter was performed twice a week postoperatively. Peritoneal dialysis was recovered 4 weeks after surgery in 2 cases with a well-maintained dialytic adequacy. One patient did not proceed to PD due to improvement of renal function after surgery.In selected PD patients, a minimally invasive surgical approach combined with careful nephrological management may represent a valid and safe strategy to treat early-stage colon cancer, avoiding PD drop-out.
