[Assessment of degree of malignancy in non-Hodgkin B-cell lymphoma with immunophenotyping]

Due to immunophenotypic examination of bioptic samples from 30 patients with non-Hodgkin's lymphoma (NHL), malignancy of B-cell NHL was identified at an early stage of diagnosis, before histological analysis yielded the results. Negative expression of T-cell antigens, monoclonal character of light-weight chains of immunoglobulins, positive expression of B-cell antigens and marked expression of CD5+ are immunologic markers of low-malignancy B-cell NHL. A similar immunophenotypic pattern, involving negative expression of CD5- and positive one for Calla-antigen as well as one identifiable by monoclonal non-cluster antibody IPO3, is a marker of highly-malignant B-cell NHL.
