Abstract
In order to identify immunohistochemical markers associated with primary refractory Hodgkin’s lymphoma, 20 patients with primary refractory form at stage IIAB in complete remission underwent histological examination and immunohistochemical determination of Bcl-6, Bcl-2, с -kit (CD117), CD15, CD30, P-53, Ki-67. In the group with primary refractory Hodgkin’s lymphoma at stage IIAB Bcl-6 expression was found in 2 patients (10%), Bcl-2 in 14 patients (70%), c-kit (CD117) in 16 patients (80%), CD15 in 9 patients (45%). The expression of CD30 and P-53 was observed in all patients in this group (100%). The expression of Ki-67 ranged from 20% to 100%, 80-100% in 16 patients (80%). As a result, multivariate analysis revealed no immunohistochemical markers of primary refractory Hodgkin’s lymphoma. In univariate and multivariate analyzes in a group of primary refractory Hodgkin’s lymphoma a high level P-53 expression (80-100%) was significantly associated with decreased overall survival. A 5-year overall survival in patients with Hodgkin’s lymphoma with the expression level of P-53 <80% was 78%, with the expression level of P-53 80-100%-22%. A 5-year overall survival of Hodgkin’s lymphoma primary patients in complete remission significantly exceeded the rates of patients with primary refractory Hodgkin’s lymphoma-100% vs. 52%.References
