Complete resection for giant thymic carcinoma after simultaneous combination chemotherapy

: A 19-year-old man visited our hospital complaining of dyspnea. Chest X-ray and computed tomography (CT) showed a huge mass in the right anterior mediastinum. We diagnosed this as invasive thymoma by microscopic examination of specimens obtained by echo-guided needle biopsy. The patient underwent 6 courses chemotherapy [1st course : carboplatin (CBDCA) + doxorubicin hydrochloride (DXR) + vincristine sulfate (VCR) + cyclophosphamide (CPA), 2nd, 3rd-6th course : cisplatin (CDDP) + ADM + VCR + CPA]. At achievement of partial response (the reduction rate of the tumor size : 91.4%), the tumor was completely resected. The pathological examination of the resected specimens yielded a diagnosis of large cell carcinoma. Preoperative chemotherapy with ADOC regimen may be effective in advanced thymic carcinoma.
