Long lasting response to the multikinase inhibitor bay 43-9006 (Sorafenib) in a heavily pretreated metastatic thymic carcinoma.
Metastatic thymic carcinoma is an aggressive neoplasm for which multimodal therapies are often ineffective. We describe here a heavily pretreated patient with advanced thymic carcinoma responsive to multikinases inhibitor BAY 43-9006 (Sorafenib). Of note, a hitherto unreported c-kit missense mutation on exon 17 (D820E) identified in tumor cells seems to explain the clinical response and highlight the key role of molecular analysis in predicting efficacy of targeted therapies even in thymic neoplasms.
