Long-term results of surgical treatment for stage cT1 kidney cancer

Abstract

Studied herein are the long-term results after surgical treatment of stage cT1 kidney cancer. The study includes 278 surgeries for kidney tumors. Partial nephrectomy was performed in 199 (71.6%) cases and radical nephrectomy in 79 (28.4%). Surgeries were performed using the open, laparoscopic, and robotic approaches. Surgical treatment and long-term oncological results were studied. Open approach for partial nephrectomy was used in 2.01% of cases, laparoscopic in 27.64%, and robotic in 70.34%; and radical nephrectomy in 2.53%, 87.34%, and 10.13%, respectively. Incidence postoperative complications after partial and radical nephrectomy were 16.58% and 3.8%, respectively. Сomplications (Clavien Dindo 3) occurred in 11.56% and 3.8% cases, respectively. Positive surgical margin occurred after partial nephrectomy in 1.51%, whereas undetermined for radical nephrectomy. The 5-year disease-free survival for partial and radical nephrectomy was 94.98 1.77% vs. 86.96% 4.11%; 5-year overall survival was 96.2% 1.55% vs. 88.15% 3.96%; 10-year overall survival was 90.82% 4.19% vs. 76.32 6.1%; and 5-year cancer-specific survival was 99.16% 0.84% vs. 94.09% 2.87%, respectively. Our study demonstrates that partial nephrectomy is a safe and effective method for surgical treatment in stage cT1 kidney cancer. A minimally invasive approach is a priority. The nephron-sparring technique demonstrates superior long-term results compared with radical nephrectomy.
