Which neoplasms of the thymus gland should be completely resected?
Because complete surgical resection is the most critical factor in long-term patient survival, all neoplasms of the thymus gland (except widely metastatic thymoma) should be completely resected. This includes thymoma, thymic carcinomas, thymolipomas, and neuroendocrine tumors (NETs) of the thymus.
