Outcomes from second-line therapy in long-term responders to first-line tyrosine kinase inhibitor in clear-cell metastatic renal cell carcinoma

Abstract

In a comparison of tyrosine kinase inhibitor (TKI) and mammalian target of rapamycin inhibitor (mTORi) in patients with metastatic clear-cell renal cell carcinoma who received a 1st-line TKI for at least 6 months, the TKI-TKI sequence was favored over the TKI-mTORi. Long-term 2nd-line responders were more likely to have received a second TKI and to have been long-term responders to a 1st-line TKI.
