Chemotherapy of invasive thymoma. A retrospective study of 22 cases.
The authors report on combination chemotherapy in 22 patients (seven men, 15 women; age 20-67, median 38.5 years) with incompletely resected invasive thymoma. Twelve of 22 patients have had prior radiotherapy of the tumor (four of 12 local failure, eight of 12 remote metastases). By subsequent chemotherapy five of 12 obtained complete remission (CR). One of them died by relapsed tumor, another by an intercurrent infection. At 5 years after diagnosis the survival rate of the 12/22 patients was 33% (Kaplan-Meier). Ten of 22 patients received chemotherapy as primary treatment of incompletely resected thymoma. Four of 10 obtained CR. One of them was lost during follow-up, the others received adjuvant irradiation of the mediastinum and are free of disease. Two of ten obtained partial remission (PR), but relapsed within 6 months after chemotherapy. At 3 years after diagnosis the survival rate of the 10/22 patients was 34%. Thirteen of 22 patients received cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) or CHOP/bleomycin as first chemotherapeutic regimen. Five of them achieved CR. Cyclophosphamide, vincristine, and prednisone (COP) or COP plus procarbazine (COPP) was administered to six of 22. Three of them obtained a CR and one a PR. In an alternating manner COPP and Einhorn regimens were given to two of 22, one of which had a CR. In one of 22 the doxorubicin, bleomycin, cisplatin, prednisone (BAPP) regimen was followed by a PR. The authors conclude that combination chemotherapy is effective in the first-line postsurgical treatment of incompletely resected thymoma and also in the treatment of local or metastatic relapses after radiotherapy.
