2. Fig 1
Surgical approaches for debated stage III cases. (A) The tumor invades the major central vessels with more than half of circumferential encasement and pericardial effusion. The case received Chamberlin open biopsy. (B) The tumor, located at the left side, with partial invasion to the left pulmonary trunk in roentgenography, is considered operable before operation. However, if, after thoracotomy, the tumor invades the pulmonary trunk and aorta, the resection becomes impossible. Then, biopsy is to be done. (C) Although the tumor, located at the right side, invades the mediastinal vital structure, sternotomy is done for resection of the tumor.

Cumulative (Cum) survival time for different stages of thymic cancer. Stage III (n = 13) and stage IV (n = 13 for a, n = 7 for b) have significant difference, but no difference is found between stages IVa and IVb.

Cumulative (Cum) survival time according to type of surgery in patients with thymic carcinoma. Complete resection (n = 7) had statistical significance, but there was no difference between debulking surgery (n = 7) and biopsy (n = 21).
