Surface marker identification of small cleaved follicular center cell lymphomas with a highly favorable prognosis. Academic Article uri icon

Overview

abstract

  • Between 1976 and 1980, 143 cases of non-Hodgkin's lymphoma have been prospectively analyzed for correlations between surface marker phenotype, histomorphology, and prognosis. This study analyzed 44 adults with tumors classified by Lukes-Collins criteria as small cleaved follicular center cell lymphomas. Two surface marker phenotypic subsets were membrane immunoglobulin, immunoglobulin D (IgD), or a receptor for the third component of the complement system (C'3) (Group I = IgD+ and/or C'3+, group II = IgD-C'3-). Eleven of the 44 patients have died with a projected median survival of 58 months. Four patients in Group I have died with a median survival of 58 months while seven patients in Group II have died with a median survival of 30 months. The difference in the survival curves for the two subgroups is statistically significant (p = 0.01). An analysis of variables such as stage, age, sex, and sites of involvement revealed no differences between the two groups. When classified histologically, the two groups were morphologically indistinguishable and had similar distributions of nodular (follicular) and diffuse variants. Of interest, five patients in Group I were judged to require no initial therapy whereas none in Group II remained untreated initially. The expression of the second heavy chain delta and/or a receptor for C'3 appears to define a subgroup of small cleaved follicular center cell lymphomas with an indolent course and an excellent prognosis.
