[The radiation and chemoradiation treatments of generalized low-grade non-Hodgkin's lymphomas. 1. The immediate results].

The remission rates were analysed during radiation and chemoradiation treatments and chemotherapy of 255 patients with low-grade generalized non-Hodgkin's lymphomas. Complete remission was achieved in 15.3% of patients, partial remission was in 82.4%. No effect was seen in 2.3% of patients. The rate of complete remissions was 4.2% for radiation treatment, 29.5% for chemoradiation, and 10.6% for chemotherapy. Chemoradiation treatment regimen was the most effective for this group of patients, in all morphological types and chiefly in Stage III. The intensified chemoradiation regimen improves the immediate outcome of treatment; a combination of series polychemotherapy with radiation applied to all diseased lymphatic collectors in a cumulative radiation dose of 30-40 Gy. The effect of the chemoradiation regimen is virtually completely revealed in the combination of three series of polychemotherapy and radiation therapy; the continued chemotherapy does not increase the rate of complete remissions.
