EGFR and hereditary clear cell renal cell carcinoma: TKIs targeting the epidermal growth factor receptor (EGFR) (e.g., gefitinib, erlotinib, afatinib, osimertinib) are currently approved for treatment of EGFR mutant non-small cell lung carcinoma (NSCLC), and multi-targeted TKIs (e.g., sunitinib, axitinib, sorafenib, pazopanib) for the treatment of renal cell carcinoma (RCC).
