[Prognostic factors in lymphosarcoma].

A comparative analysis of the long-term results of treatment of 709 lymphosarcoma patients has shown that the main prognostic factor determining the patients's survival was a morphological tumor type. Therapeutic policy with regard to prognostic factors was proposed for lymphosarcomas. Lymphosarcomas of a high degree of malignancy required intensive therapy using cycle polychemotherapy, whereas monochemotherapy was recommended for patients with lymphosarcomas of a low degree of malignancy. Treatment of stage I-II mediastinal lymphosarcomas should be very intensive and prolonged.
