As disease progression is inevitable, most patients will receive several lines of treatment. However, the choice regarding which sequence of drugs to use remains unclear, particularly concerning the drug class, i.e. those targeting the vascular endothelial growth factor (receptor) [VEGF(R)] pathway versus those acting on the mammalian target of rapamycin pathway. There appears to be no absolute crossresistance between tyrosine kinase inhibitors (TKIs) acting on the VEGF(R) pathway, and there have been numerous reports of two TKIs being successfully used in sequence. We report the case of a 63-year-old woman who responded for 24 months to three successive lines of treatment with different TKIs (sunitinib, axitinib and sorafenib). This suggests that TKIs targeting VEGFR should be considered as individual drugs and not as a single class.
