Abstract 1902


VEGF- and mTOR-directed therapies are the mainstay of mRCC treatment. Guidelines recommend risk stratification for treatment selection. Here, we examined how demographics and comorbidities may impact treatment selection.


Patients (pts) initiating 1L mRCC therapy from 2011 to 2013 were identified in MarketScan, a US claims database with ≈40 million pts with employer-sponsored insurance. Pts with non-RCC histologies and previous primary cancers were excluded. Pts were stratified by 1L drug category (VEGF- or mTOR-directed) and dosage form (intravenous [IV] or oral [PO]). Clinical and demographic characteristics (eg, age, sex, employment, region, insurance type), baseline comorbidities, and Charlson Comorbidity Index (CCI) were assessed. Multivariate logistic regression models examined associations between these characteristics and receipt of (1) VEGF- vs mTOR-directed and (2) IV vs PO therapy.


1262 mRCC pts initiated 1L therapy between 2011 and 2013 and met selection criteria. Median age was 62 y; 70% were male; 84% had a CCI of 0-1, with diabetes (26%) and chronic kidney disease (19%) being the most frequent. VEGF-directed therapy was more common than mTOR-directed therapy (87% vs 13%). PO therapy was more common than IV therapy (83% vs 17%). Diabetes was more common in pts taking VEGF-directed therapy, while the opposite was seen for CHF; these factors remained independently associated with 1L therapy in multivariate analyses (Table). Pts receiving IV therapy were older than those receiving PO therapy (mean, 65 vs 62 y), and age remained significant in the multivariate-adjusted model (P = .04).

Baseline diabetes and CHF as well as age are independent predictors of 1L mRCC treatment selection. Differences in treatment safety profiles and pt health may drive this difference. These results will inform ongoing studies that compare treatment selection in 1L mRCC.
