Salvage surgery for recurrent transdiaphragmatic thymoma in a patient not eligible for chemotherapy

Abstract

Abstract The recurrence rate following thymoma surgery has been reported to be as high as 29%. In cases of localized recurrence, complete resection can result in prolonged patient survival. However, surgery is rarely considered in cases of invasive recurrent thymomas with high disease burden. Here, we present the case of a woman with type B2 thymoma (Masaoka–Koga stage IVa) treated with surgery, chemotherapy, and radiotherapy. The disease recurred 6 years later, with invasion of the left lung and the 12th thoracic vertebra, as well as extension into the retroperitoneum. Due to the development of chemotherapy-associated toxicity, she underwent surgery with complete tumor resection and has remained free of disease at a 12-months follow-up. Radical surgery for recurrent invasive thymoma extending through the diaphragm is a feasible and safe therapeutic option in highly selected patients who are not eligible for systemic treatments.
