Twenty pediatric patients with Ewing's tumor seen at Roswell Park Memorial Institute, from 1954 to 1970, have been analyzed. Three patients are considered as cures. As the initial treatment, these three patients were all treated with radiotherapy to the primary tumor and adjuvant chemotherapy. Nine of the 20 patients were treated in this fashion. It was felt that the chemotherapy eradicated the subclinical micrometastasis and thus effected a cure. Five cases with reactivation of primary sites prior to, or simultaneous with, metastasis were noted, indicating incomplete sterilization of tumor by present radiotherapeutic techniques and also suggesting that more aggressive therapy be directed to the primary site along with the systemic chemotherapy.

From 1921 to 1973, 106 children with Hodgkin's disease under the age of 17 years were seen at Roswell Park Memorial Institute and were analyzed retrospectively. Evaluation was separated into three eras: 1921-1949 (early era), 1950-1964 (middle era), and 1965-1973 (recent era). In the early era, suboptimal radiation therapy was employed. In the middle era, radiation therapy techniques were improved, and single-agent chemotherapy was introduced. In the recent era, multiagent chemotherapy routines were frequently used; aggressive external megavoltage radiation therapy became routine in conjunction with improvement in staging procedures. The best survival was observed in the recent era where five-year survival of 96% was noted in early stage disease. Favorable prognostic features included: younger age group (5-9 years), female sex, lymphocytic predominant histology, early stage disease, and complete response to therapy. Nodular sclerosing and mixed cell types had an equal prognosis. The concept of involved area radiotherapy along with combination chemotherapy appears a reasonable approach in children and should be tested in a randomized study against more extensive radiotherapy techniques in early stage disease.

Two cases of Kaposi's sarcoma involving the oropharynx are described. The pathology of the condition is reviewed and the problems of treatment outlined.
