Beyond metastatic renal cell carcinoma (mRCC) clinical trials: Targeted therapy use and overall survival in community oncology clinics.

e15061 Background: Targeted therapies are now the standard of care for mRCC with use and expected outcomes defined by clinical trials. What are "real world" patterns of use and survival outcomes in mRCC patients (pts) treated in community oncology (COMM) settings? Methods: We reviewed a retrospective registry of adult mRCC pts from 11 COMM oncology practices, diagnosed since 1/2007 and not enrolled in a trial. Demographics, disease characteristics, treatment patterns and outcomes were recorded from the EMR and supplemented with chart abstraction.Pts were grouped by treatment sequence reflecting up to 3 exposures based on drug mechanism of action (VEGFR TKI [TKI] or mTOR inhibitor [mTOR]). Other pts received a non-TKI, non-mTOR therapy in the 1st three exposures (e.g., bevacizumab, cytokines, combinations, etc.). No Therapy pts received no systemic therapy as of data analysis. Survival analyses included Kaplan-Meier methods and Cox regression. Results: 255 patient/disease characteristics included: age 65±1...
