Therapy for thymic epithelial tumors: a clinical study of 1,320 patients from Japan
Phase observationalN = 1,320
- Population
- 1,320 patients with thymic epithelial tumours (thymoma, thymic carcinoma and thymic carcinoid) treated 1990-1994
- Design
- Compilation of the records of 1,320 patients with thymic epithelial tumours treated from 1990 to 1994 in 115 institutes certified as special institutes for general thoracic surgery by the Japanese Association for Chest Surgery. Survival is reported by Masaoka stage and extent of resection. Not randomised; the abstract does not state the analysis methods.
- Arms
- Total resection (experimental): Total resection of the tumour
- Subtotal resection (control): Subtotal resection of the tumour
- Inoperable (control): Not operated (inoperable group)
- People
