Abstract

Summary Introduction. The incidence of malignant neoplasms in population of patients initiat- ing renal replacement therapy (RRT) is rising last years, which is related to the aging of general population and to the increasing availability of renal replacement therapy to renal patients, including those with neoplastic diseases. Aim. The aim of this work was to analyse the frequency of malignant neoplasms in the group of patients starting renal replacement therapy. Material and methods. The retrospective analysis of the medical records in years 2001-2015 at the Dialysis Unit in the Priest J. Popieluszko Bielanski Hospital in Warsaw. Results. The RRT was started in 669 patients (F-270, M-399) and 84 of them (12.5%) had malignant neoplasm at the RRT start. The largest group - 23 persons (27.4%) were patients with the neoplasm of lymphatic system, most of them with multiple myeloma. Conclusions. The incidence of malignancies at the commencing of chronic RRT in the 669 consecutive patients at our dialysis unit, was 12.5%, in this the malignancies of lymphatic system were 3.4% (23/669) - 3.3% (9/270) and 3.5% (14/399) in woman and man, respectively.
