[The effectiveness and toxicity of therapy in primary Hodgkin's lymphoma with extranodal lesions].

Using of radiochemotherapy improves short-term and long-term results of treatment in patients with primary Hodgkin's lymphoma (HL) comparing with treatment by chemotherapy alone. The rates of 5-year, 10-year OS and DFS are 88%, 83% and 90%, 86% in case of radiochemotherapy, versus 73%, 66% and 72%, 68% using chemotherapy alone. The 5-year and 10-year OS, DFS estimates in treatment with ABVD are 84% and 83%, 75% and 74%; BEACOPP-baseline--83% and 82%, 82% and 81% (p < 0.05). At the same time ABVD chemotherapy develops less toxicity (p < 0.001). The treatment with 6 cycles of ABVD is considered as the most appropriate in primary Hodgkin's lymphoma patients with extranodal lesions. Using more than 6 cycles doesn't seem to improve OS and DFS (the 5-year and 10-year DFS, OS estimates are 79% and 72%, 80% and 77% versus 88% and 87%, 90% and 89% (p < 0.05). Comparison of complications rate during chemotherapy with MOPP (919 cycles), ABVD (1300 cycles), BEACOPP-baseline (584 cycles), BEACOPP-escalated (140 cycles) reveals major hematologic toxicity and infectious complications rate in BEACOPP-escalated program (p < 0.05).
