Abstract
Aim:To investigate the prognostic significance of clinical and pathological factors of non-metastatic renal cell cancer after surgery.Patients and methods:We conducted a retrospective cohort study based on the records of patients with non-metastatic renal cancer submitted to radical or partial nephrectomy between 2000 and 2015 in Salah-Azaiez Institute.Results:Median follow-up was 38 months (interquartile range: 20–64). Five-year overall and disease-free survival were 53.8% and 43.1%. In the multivariate setting, lymph node invasion (p = 0.01), clear cell renal carcinoma subtype (p = 0.014), and tumor necrosis (p = 0.009) were the only independent statistically significant predictors of disease-free survival, while Fuhrman grade (p = 0.025), clear cell renal carcinoma subtype (p = 0.044), and TNM stage (0.041) were the only factors correlated with overall survival.Conclusion:For patients with non-metastatic renal cell carcinoma, independent predictors of disease-free survival and overall survival were clear cell renal cell carcinoma, Fuhrman grade, TNM stage, lymph node invasion, and tumor necrosis. Such information could be used to guide the intensity of follow-up and identify high-risk patients who can be targeted for adjuvant therapy trials.
