[Primary refractory and relapsed Hodgkin lymphoma with unfavorable prognosis].

ABSTRACT

In this retrospective clinical study 100 patients with primary unfavorable prognosis stage II Hodgkin lymphoma (HL) (n = 50) or stage IV HL (n = 50). The ABVD chemotherapy allowed to achieve remission in 90% of cases with 5-year relapse-free survival (RFS) and overall survival (OS) of 64% and 92%, the basic BEACOPP regimen lead to the same 90% remission rate with 74% DFS and 94% OS. These results for ABVD and basic BEACOPP regimens are characterized by similar statistic values (p = 1.0; p = 0.6; p = 0.9), although the use basic BEACOPP lead to statically valid decrease of grade III-IV toxicity (p = 0.005). The occurrence of primary refractory HL was slightly higher in basic BEACOPP group (18% versus 10% in ABVD group), although this difference had no statistical value (p = 0.3) and was probably due to higher number of patients with > 1 extranodal localizations. The occurrence of primary refractory HL correlated to disease stage 6% in stage II and 22% in stage IV (p = 0.04). HL relapse frequency in ABVD and BEACOPP groups was similar (12% and 8%), there was no statistically valid difference (p = 0.5). In ABVD and basic BEACOPP recipients with stage II/IV HL the primary refractory disease rate was 15%, relapse rate was 10%. Five-year OS in primary refractory and relapsed patients was lower, than in general patient population (64% and 70% compared to 80%), although the difference had no statistical significance (p = 0.6, p = 0.7).
