A patient who had undergone amputation and adjuvant chemotherapy with methotrexate doxorubicin hydrochloride for osteosarcoma of the femur later developed granulomatous hilar and paratracheal lymphadenopathy and multiple pulmonary nodules. Biopsy of the nodules showed noncaseating granulomas typical of sarcoidosis. Hilar adenopathy and granulomatous pneumonitis have been reported following methotrexate therapy, but a roentgenographic pattern of isolated, discrete pulmonary nodules has not been described. Treatment with immunosuppressive chemotherapy may have inhibited the development of sarcoidosis, which became manifest only after cessation of the chemotherapy.

Methotrexate is now used widely for the treatment of acute leukemia, non-Hodgkin's lymphoma, osteogenic sarcoma, choriocarcinoma, breast carcinoma, pulmonary and epidermoid carcinoma, and intrathecal chemotherapy. It is also useful in bone marrow transplantation, severe psoriasis, rheumatoid arthritis, dermatomyositis, Wegener's granulomatosis and sarcoidosis. The recent dramatic intensification of methotrexate therapy can be attributed in part to advances in our understanding of the clinical pharmacology of the folate antagonists, as well as to the combination of positive results and their effective dissemination to medical oncologists. The review summarizes the pharmacologic findings and illustrates how they are currently being applied to the treatment of malignant disease.

A significant amelioration of treatment results is achieved by sequential chemotherapy and radiotherapy in patients with lymphogranulomatosis of stage IIb to IVb and in patients with non-Hodgkin's lymphomas in corresponding stages. Similar results will probably be obtained in patients with small cell bronchial carcinomas in a limited stage. Patients suffering from an initially inoperable ovarian cancer often reach an operable condition by sequential chemotherapy and radiotherapy. In the stages Dukes B2 and C of the rectum carcinoma, preoperative and/or postoperative irradiation significantly reduces the recurrence rates and increases the survival times. A considerable reduction of recurrence rates is obtained by postoperative radiotherapy in soft tissue sarcomas of the stages T1 to T3. Another improvement is anticipated by a neutron or neutron boost irradiation for stage T3 and by adjuvant chemotherapy for G3 tumors. In the osteosarcoma of adult persons, the results of the limb-sparing sequential therapy will not be worse than the results achieved by amputation. Retrospective analyses of the long-term results of radical mastectomy and conservative operation with postoperative irradiation in case of mammary carcinoma did not show any difference for the stages T1 to T3, N0 to N1.

The results of morphologicl examinations of some soft tissue sarcomas, osteogenic sarcoma, and lymphogranulomatosis after radiation therapy are presented. Morphological changes developing after radiation and drug therapy of tumors are similar, only the extent of their intensity, vascular reaction, and changes in the adjacent tissues are different. Five cases of acute leukemia developing in patients with lymphogranulomatosis in the presence of long-term cytostatic therapy are described.
