Regimen

Study	Evidence
Fornasiero et al. 1991	Retrospective

Note: The body of Fornasiero et al. 1991 specifies that cycles are given every 3 weeks. However, the abstract says that cycles are given "at monthly intervals," and the NCCN, Thymomas and Thymic Carcinomas version 2.2012, lists the regimen as being given every 4 weeks.

Chemotherapy

• Doxorubicin (Adriamycin) 40 mg/m² IV once on day 1
• Cisplatin (Platinol) 50 mg/m² IV once on day 1
• Vincristine (Oncovin) 0.6 mg/m² IV once on day 3
• Cyclophosphamide (Cytoxan) 700 mg/m² IV once on day 4

21 to 28-day cycles--see note above regarding duration of cycles

  • If tumor is incompletely resected or has <80% necrosis, 60 Gy radiation therapy is administered

One course, followed by consolidation:

Consolidation chemotherapy
