Abstract
INTRODUCTION
In clinical stage I renal cell carcinoma (RCC), partial nephrectomy (PN) is actual recommended surgical technique. However, poor pathological tumor features have more negative prognosis. We aimed to evaluate the effects of performing partial or radical nephrectomy(RN) on local recurrence, distant metastasis and cancer-specific survival in stage pT1 RCC with high Fuhrman grade.
METHODS
Data of patients who underwent PN or RN due to pathological stage pT1 RCC with high Fuhrman grade, between January 2009 and July 2016 were retrospectively evaluated. 66 of them whose datas were fully accessible, were included to study. Demographic datas, histological tumor types, Fuhrman grading, local recurrence, distant metastasis and survival rates after nephrectomy were recorded. The patients were divided into two groups as RN (Group I) and PN (Group II).
RESULTS
Mean age of patients was 57.67±10.23. Among them, 6(9.1%) patients had local recurrence, 8(12.1%) had distant metastasis and 8(12.1%) had cancer related death. Group II had higher local recurrence rate (11.1%, p=0.532), distant metastasis rate (18.9%, p=0.630), cancer-specific survival (94.16 months, p=0.560); lower predicted recurrence-free survival (89.46 months, p=0.433) and metastasis-free survival (84.94 months, p=0.617). But there were no significantly difference. In multivariate analysis, hypertension for local recurrence; Fuhrman grade 4, female gender, BMI>27 for distant metastasis, and estimated glomerular filtration rate<90 for cancer-specific survival were independent predictive factors.
DISCUSSION AND CONCLUSION
We found that PN or RN did not significantly alter the oncologic outcomes in follow-up of patients with high Fuhrman grade, stage pT1 RCC. For this reason, it is more appropriate to use nephron sparing technique.
