Follicular and diffuse mixed small-cleaved and large-cell lymphoma. A clinicopathologic study

Abstract

The clinical records and initial biopsy materials from 76 patients with mixed small-cleaved and large-cell lymphoma containing both a follicular and diffuse architectural pattern were reviewed. The characteristics of this group, treated at Stanford University Medical Center (SUMC) between 1963 and 1983, are described. The 5-year actuarial survival and freedom from progression are 70% and 27.5%, respectively. Classification according to the degree of follicularity indicated that patients with focally follicular areas (ie, < 25% of the histologic section) have a significantly worse freedom from progression and overall survival at 5 years compared with those patients with a predominantly follicular architecture (ie, > 50% follicular areas). Based on our analysis, we feel that the degree of follicularity is an important prognostic factor and that mixed lymphoma patients with only focally follicular areas behave more like an intermediate-grade lymphoma and should be treated aggressively.
