A prospective risk-stratified follow-up programme for radically treated renal cell carcinoma patients: evaluation after eight years of clinical use

Purpose In mid-2007, we introduced a new risk-stratified follow-up programme (FUP) for surgically treated localized renal cell carcinoma. After inclusion, the patients have been followed prospectively. In this study, we present the results in regard to stratification, completeness of the FUP and recurrences. Methods The FUP consists of three risk groups: low risk (LR), intermediate risk (IR) and high risk (HR), based on the risk stratification model introduced by Leibovich et al. (Cancer 97(7):1663–1671, 2003 ). In all risk groups, the patients are scheduled for ten follow-up visits (FUV) over 5 years, but seven, five and three FUVs, respectively, are outsourced to the patient’s general practitioner (GP). Chest X-ray and abdomen CT are the imaging modalities used in the FUP. Results Of 312 included patients, 195 (62.5 %) had a complete FUP. However, in 86 patients the scheduled FUP had to be reduced, leaving 86.3 % of the remaining patients with a complete FUP. By including GPs, the number of FUVs at the hospital was reduced by ~60 %. The 5-year probability for freedom of recurrence is 0.98, 0.84 and 0.52 for the LR, IR and HR groups, respectively. Of 31 recurrences, 20 patients (65 %) were diagnosed within the FUP. Eleven patients (35 %) were diagnosed due to symptoms, and five of these had recurrences in locations not covered by standard imaging. Patients diagnosed within the FUP showed a better prognosis for survival and could in greater part receive tumour-directed treatment. Conclusions After 8 years of clinical use, the outcome measures of the FUP seem to be within acceptable ranges.
