[A retrospective analysis of functional and oncologic outcomes following surgical treatment of patients with pT1/pT2 renal cell carcinoma at a tertiary referral centre].

INTRODUCTION  In patients with localised renal cell carcinoma, the only curative treatment option is surgical tumour excision. The aim of this study was to evaluate peri- and postoperative outcomes as well as oncologic and functional long-term results following surgical treatment of patients with renal cell carcinoma (pT1/pT2) at a tertiary referral centre. PATIENTS AND METHODS  This retrospective study included a total of 758 patients with localised renal cell carcinoma (pT1 /pT2), who underwent radical (RN) or partial (PN) nephrectomy between 01/2008 and 10/2014. Pre-, peri- and postoperative parameters were recorded. Oncologic and functional long-term data were retrieved through questionnaires and structured telephone interviews. RESULTS  Laparoscopic RN or PN resulted in less blood loss and lower peri- and postoperative complication rates compared to open procedures. Regarding short- and long-term renal function, a higher increase in serum creatinine levels was detected after RN. No difference was noted in health status and quality of life. Median follow-up was 36 months. A total of 10.4 % of patients died during follow-up. 4.7 % and 8.4 % developed a relapse or metastatic disease. No difference was found between laparoscopic and open RN/PNs in terms of oncologic long-term results. DISCUSSION  In conclusion, all surgical techniques evaluated in this study provided good oncologic and functional short-/long-term outcomes.
