ABSTRACT
BACKGROUND:
Thymic carcinoma is a type of rare and highly malignant tumor that originates from the thymic epithelium. Treatment and prognosis of thymic carcinoma remain controversial. We retrospectively analyzed survival data from a large-sample multicenter database in China.METHODS:
The Chinese Alliance for Research of Thymoma constructed a retrospective database of patients with thymic epithelial tumors, which enrolled 1930 patients from January 1996 to August 2013, including 329 with thymic carcinomas. In this study, we analyzed clinical, pathologic, and treatment information, measured long-term survival rates, and identified relevant prognostic factors.RESULTS:
Of 329 patients, R0 resection was performed in 211 (57.7 %), R1 in 34 (9.2 %), and R2 in 84 (22.5 %).The 3-, 5-, and 10-year survival rates were 78.3, 67.1, and 47.9 %, respectively. In univariate analysis, early Masaoka-Koga stage, R0 resection, and postoperative radiotherapy were associated with better overall survival.Early Masaoka-Koga stage and postoperative radiotherapy were also associated with disease-free survival. In multivariate analyses, R0 resection, Masaoka-Koga stage, and postoperative radiotherapy were significant prognostic factors of survival.CONCLUSIONS:
Complete resection is the preferred primary treatment for thymic carcinoma. R0 resection, early Masaoka-Koga stage, and postoperative radiotherapy are significant predictors of improved survival.
