Background: Sunitinib is a first line treatment for majority of patients with metastatic RCC. The recommended dose of 50mg often results in a spectrum of serious side effects which subsequently lead to dose reduction and may have an impact on response rates. Methods: We conducted a retrospective analysis of 62 RCC patients from single institution treated with sunitinib between September 2007-May 2010. Patients were stratified according to age groups, into ≤ 70 year old (y.o.) and > 70 y.o. to compare tolerability, response rates and median survival. Results: All patients were evaluable for toxicity, 55 patients were evaluable for response. 38 (61.2%) were ≤ 70 y.o. and 24 (38.8%) were >70y.o. 2 patients (5%) of ≤70 and 5 (20%) of > 70y.o. were non-evaluable for response due to early treatment discontinuation. The response rate was 36% in ≤70y.o. and 21% in >70 y.o., stable disease (SD) was observed in 41% ≤70 y.o. vs 47% in the older age group and progressive disease PD:22% vs 31.5% respectively. 24 (38.7%) of patients required dose reductions after the first or second cycle- 12 (33%) in ≤70 vs 11 (59%) in >70 yrs old. A small number of patients presented with PS 2 and these were started on a reduced dose of 37.5mg: 3 (8%) in ≤70y.o. and 11 (58%) > 70y.o. Toxcities were comparable in both groups however grade 3 palmar-plantar erythema (PPE) and mucositis (18% vs 1.6% and 18 vs 8% respectively) were more prevalent in the younger cohort. Grade 3 diarrhoea and fatigue were more common in older patients (10% in >70y.o vs 1.6% in ≤70y.o. and 16% vs 9.6% respectively). Median survival was 23 months for both age groups. Conclusions: Elderly patients more commonly require dose reduction due to poor performance status and toxicity profile. The objective response rate is lower with the lower dose intensity however the rate of disease stabilisation is comparable in both groups. The lower dose of Sunitinib is well tolerated in the elderly and this regimen should be considered for older patients with poor performance status.
