ABSTRACT
BACKGROUND:
There are no data on the patterns of care and outcome of elderly patients with mRCC treated with sunitinib. In a retrospective study, we assessed the routine use of first-line sunitinib in mRCC patients aged ≥ 70 years. PATIENTS ANDMETHODS:
We reviewed the clinical files of 185 patients aged ≥ 70 years with mRCC treated with first-line sunitinib in 17 Italian oncology units from February 2006 to September 2011. One hundred twenty-three patients (66.5%) received a standard 50 mg/d for a 4 weeks on/2 weeks off regimen (SR), and 62 patients (33.5%) received an AR consisting of 37.5 mg/d for a 4 weeks on/2 weeks off in 67.7% of cases.RESULTS:
Median age was 74 years. Patients treated with an AR were older than those treated with the SR (P < .0001). In the overall population, the median progression-free survival (PFS) was 11 months, and the median overall survival (OS) was 25.5 months. Grade 3-4 toxicities occurred in 87 of 123 SR (70.7%) and 32 of 62 AR (51.6%), respectively; dose reductions were required in 82 SR (66.7%) and 26 AR (41.9%), respectively; discontinuations because of therapy-related adverse events occurred in 25 SR (20.3%) and 15 AR (24.2%), respectively. In multivariate analysis, only performance status and the Heng score were predictors of either PFS or OS.CONCLUSION:
Sunitinib is active and feasible in elderly patients with mRCC. A sunitinib AR could be considered as an option in selected older mRCC patients. The optimal treatment of frail patients with mRCC remains to be established.Palabras clave
