title: [High-dose methylprednisolone-containing chemotherapy in advanced invasive thymoma--report of three cases].
abstract: During the period from May, 1995 to August, 1996, three patients with Stage III or IVa invasive thymoma received chemotherapy consisting of cisplatin, doxorubicin and methylprednisolone (1000 mg on days 1 through 5, and 500 mg on days 6 and 7). The first case, a 55-year-old woman, who underwent extended thymectomy 7 years ago, was found to have a recurrent tumor in the left pleural cavity. The second case, a 38-year-old man, who had first operation 3 years ago, developed recurrent tumor in the right pleural cavity. These two patients were treated with the above regimen as the primary mode of therapy. The third case, a 61-year-old woman, had a thymoma with direct invasion to right upper lobe. The same chemotherapy regimen was employed as the induction chemotherapy. All patients showed a major response to treatment with only a small amount of tumor remaining. The effectiveness of chemotherapy in the treatment of malignant tumors has been recently reported to be at least partly due to induction of apoptosis. Steroids are known to induce apoptosis in normal thymic cells, and thus steroid in chemotherapy regimen against invasive thymoma may enhance the effect of anti-cancer drugs through the induction of apoptosis.
