[Relapse in Hodgkin lymphoma].

The retrospective study revealed the 15% relapse rate in patients with stage II-IV unfavorable prognosis Hodgkin lymphoma, 5-year OS in relapsed patients was 84%. Karnofsky score less than 80 (p=0,0001), more than 1 extranodal lesion (p=0,0004), extensive (equal to stage III-IV) involvement on relapse (p=0,001), b-symptoms on relapse (p=0,023), more than 5 lymph nodal lesions (p=0,027), albumin level less than 40 g per liter (p=0,037), detection of new nodal lesions (p=0,041) were shown by discriminative analysis as the therapy effect predictors in patients with Hodgkin lymphoma relapse. In patients with second-line therapy failure the actuarial survival rate was lower by 55% in comparison to patients with chemosensitive relapses (40% and 95%). The secondary therapy resistance was shown to be an unfavorable prognosis predictive factor (p=0,0001). The multifactorial overall survival analysis revealed the following adverse prognostic factors: failure of second-line treatment (p=0,0001), first early relapse (p=0,01), albumin level on relapse less than 40 g per liter (p=0,02), use of standard chemotherapy instead of irradiation (p=0,02). The relapse patients with 1 or less risk factors had 95% 5-year OS, the patients with 3 or more adverse risk factors had 70% OS (p=0,0002). The lowest 10-year OS was observed in patients with 2 or more adverse risk factors, 48% and 28% accordingly. Adverse risk factors must be considered while choosing the optimal treatment strategy aimed at better survival rate.
