Introduction: Recurrence of renal cell carcinoma depends mainly on tumor stage at the time of radical nephrectomy and increases with increasing T-stage. Up to 30% of patients with T1-2 tumors will experience local or distant recurrence. Recommendations for the follow-up include chest x-ray every 6 months for stages T1-4 and abdominal CT-scan for pT3-4 for the first 3 years. The aim of our study was to identify prognostic factors predicting recurrence of RCC in order to individualize follow up strategies.

Patients and Methods: We retrospectively analyzed the charts of 177 patients with RCC who underwent radical nephrectomy. In 163/177 (92%) of the patients the histology revealed renal cell carcinoma. The median-follow up was 4.5 (1-6) years. The prognostic significance of histology, gender, age, c-reactive protein, hemoglobin, hematuria, gross hematuria, weight loss, flank pain and metastases at the time of surgery for risk of recurrence was calculated by uni- and multivariate analysis. Cancer specific survival (CSS) was analyzed by the Kaplan-Meir method.

Results: Logistic regression analysis identified presence of metastases at time of surgery (p=<0.0005), hematuria (p=<0,0005) and flank pain (p=0,011) as independent prognostic factors for the recurrence of RCC. The risk of recurrent disease is 33.5% with one, 70 to 83% with two and 95.6% with the presence of all 3 markers. 3-year CSS is 69% vs. 82% in symptomatic vs. asymptomatic patients (p= 0,1352), 45% vs. 90% in M1/N1 vs. M0/N0 (p=0.0001) and 78% vs. 88% in pT3b vs.
