Background: It is well established that RCC is one of the most important complications in hemodialysis patients. However, the influence of the HD duration on RCC has not been determined. Therefore, this study determined if the HD duration relates to the pathological type and prognosis.
Design: This study consisted of 69 patients on HD (73 kidneys) who underwent a radical nephrectomy for RCCs from January 1991 to December 2008. We classified the patients into three groups based on the duration of HD (Group 1: less than 10 years; Group 2: from 11 to 20 years; Group 3: over 21 years). All cases were reviewed without clinical information, and the pathological type and parameters were recorded.
Results: The patients who received HD for more than 10 years showed a distinctive distribution of the pathological type (p=0.01) and pT stage (p=0.003), as listed in Table 1.
