ABSTRACT
INTRODUCTION: Treatment advances in metastatic renal cell carcinoma (mRCC) have improved overall survival (OS) in mRCC patients over the last two decades. This single center retrospective analysis assesses if the purported survival benefits are also applicable in elderly mRCC patients.
METHODS: 401 patients with mRCC treated at Hannover Medical School from 01/2003-05/2016 were identified and evaluated by chart review. Treatment periods were defined as 01.01.2003-31.12.2009 (P1) and 01.01.2010-31.05.2016 (P2). Age groups were defined according to WHO classes (≤ 60 years: younger, > 60-75 years: elderly and > 75 years: old). Descriptive statistics, Kaplan-Meier analysis and logistic regression were performed.
RESULTS: Median OS improved from 35.1 months in P1 to 59.1 months in P2. Sub-division into the respective age groups revealed median survival of 38.1 (95%-CI: 28.6-47.6) months in younger patients, 42.9 (95%-CI: 29.5-56.3) months among elderly patients and 27.3 (95%-CI: 12.8-41.8) months among old patients. Risk reduction for death between periods was most evident among old patients (young: HR 0.71 (95%-CI: 0.45-1.13, p = 0.2); elderly: HR 0.62 (95%-CI: 0.40-0.97, p = 0.04); old: HR 0.43 (95%-CI: 0.18-1.05, p = 0.06)). Age ≥ 75 years was an independent risk factor for death in P1 but not in P2.
CONCLUSION: Improved OS in the targeted treatment period was confirmed. Surprisingly elderly and old patients seem to profit the most form expansion of therapeutic armamentarium, within the TKI-dominated observation period.
