Abstract
Minimally invasive surgery (MIS) has occasionally been used for selected patients with thymoma, but there is little information on the MIS approach for thymic carcinoma. The aim of this study was to evaluate survival outcomes after MIS for early-stage (Masaoka stage I-II) thymic carcinoma and thymic neuroendocrine carcinoma. A retrospective chart review of the cases recorded in our multi-institutional database was performed to identify patients who underwent resection for thymic carcinoma between 1995 and 2017. MIS thymectomy was performed in 17 cases (VATS, n = 14; RATS, n = 3. male, 41%; median age, 72years). The median follow-up period was 32.7 (range 7.4-106) months. The five-year overall survival and relapse-free survival rates were 84.4% and 77.8%, respectively. The present study demonstrated encouraging preliminary results regarding MIS for the treatment of early-stage thymic carcinoma and thymic neuroendocrine carcinoma. Further studies with a larger sample size are required to evaluate the indications for this surgery.
