SAN FRANCISCO— Plasma and tumor biomarkers including FGF, C-KIT and VEG-F were found to yield prognostic information which could help guide therapies, according to research findings presented at the 2014 ASCO Genitourinary Cancers Conference. Professor Bernard Escudier MD from the Institut Gustave Roussy in Villejuif near Paris discussed results from a biomarker analysis of the multinational phase III randomized GOLD study looking at “third-line” therapy for metastatic renal cell carcinoma with the FGF-directed agent dovitinib compared with sorafenib in patients with metastatic renal cell carcinoma after one prior VEGF pathway–targeted therapy and one prior mTOR inhibitor therapy. High baseline cKIT and low baseline FGF2, HGF, PlGF, sVEGFR1, VEGFA, and VEGFD were associated with better overall survival in patients treated with either sorafenib or dovitinib, and the analysis concluded that baseline plasma biomarkers are prognostic but not predictive in the third-line setting.
