summary
- objective
- The aim of this paper was estimation of morphological and clinical differences and the results after NSS in accordance to the position of renocellular cancer (RCC) in the kidney.
- Material and methods. The analysis was performed in 108 patients with contralateral healthy kidney. They were divided into 3 groups. 1) 50 patients with lower pole kidney tumor. 2) 28 patients with tumor in the middle part of the kidney. 3) 30 patients with upper pole kidney tumors. The follow-up was carried up according to EORTC recommendation during the 5-194 months (average 64,7 m-th). 13 selected factors which could influence on the outcome of NSS were statistically analyzed.
- results
- The lower pole tumors were associated with statistically significant highest survival time and the lowest percent of the tumors with RCC typical histological structure. Patients with tumor in the middle part of kidney showed significantly highest percentage of intraoperative ischaemia, complications and transfusions. Patients with upper pole tumors had significantly lowest survival time, highest percentage of RCC typical tumors, with highest grade and kidney's parenchyma resection.
- conclusion
- Tumor location in the kidney influenced survival time, and characteristics of selected clinical and morphological tumor factors.
