Treatment of Operable or Potentially Operable Stage III or Stage IV Thymoma
Clinical Scenario
This protocol addresses patients with stage III or stage IV thymoma who have been assessed as operable or potentially operable. Treatment options vary depending on the degree of resectability established after initial work-up, and a multidisciplinary evaluation is central to determining the appropriate path.
Patient Population
Surgical resection with curative intent should be considered for all patients deemed to have resectable stage III thymoma after the initial work-up. For those with potentially operable but not immediately resectable disease, an alternative combined-modality strategy may be evaluated to achieve operability.
Treatment Approach (Partial Overview)
Management typically involves a surgical approach — either as the primary intervention or following induction chemotherapy — combined with radiation therapy. The complete sequencing, regimen selection, and criteria for each pathway are detailed in the full structured protocol.

- Commonly used induction chemotherapy regimens include combinations of cisplatin, doxorubicin, and cyclophosphamide, or cisplatin and etoposide.
