Objective: Some prognostic models have been described for localized and metastatic renal cell carcinoma (RCC). The European Association of Urology guidelines on RCC recommend using these models. However, there is no model for T1 and T2. The study evaluated the risk factors for recurrence in T1 and T2 RCC. Materials and Methods: Data of 4823 renal tumor patients from the Renal Tumor Database of the Association of Urooncology in Turkey were evaluated. Of 4823 patients, 1845 RCC patients with pathological T1 or T2 were included in this study. The patients were divided into two groups according to the recurrence status. Anatomical, histological, and clinical prognostic factors were statistically compared between the groups. Afterwards, multivariate analysis was performed for the variables that were found to be statistically significant. Results: The mean follow-up time was 30 (4-180) months. Of 1845 RCC patients, 117 (6.3%) had recurrence. Univariate analysis revealed statistically significant differences between age, preoperative hemoglobin, albumin, neutrophil, alkaline phosphates, platelet and calcium values, histological subtype, Fuhrman grade, surgical technique (radical or partial), and pathological stage in the groups. However, in multivariate analysis, only pathological stage was found to be a risk factor for recurrence (2.17 95%, 1.25-3.77). Conclusions: The results of our study show that it is difficult to design a prognostic model for the recurrence of pT1 and pT2 RCC. We suggest that patients with a higher tumor diameter should be followed up more frequently.
