Abstract
The prognostic relevance of CD5 expression in marginal zone lymphoma (MZL) remains poorly characterized. We aimed to compare baseline characteristics and outcomes of patients with CD5+ MZL and CD5– historical matched controls. We hypothesized that patients with CD5+ MZL may have similarities to other CD5– expressing B-cell lymphomas, which may be informative when considering alternative therapeutic approaches for this MZL subgroup. We retrospectively analyzed 64 patients with CD5+ MZL and 137 CD5– MZL controls matched on age at diagnosis and sex. The CD5+ and CD5– cases did not differ in terms of mucosa assiociated lymphoid tissue (MALT)–lymphoma International Prognostic Index or incidence of nodal involvement. Bone marrow involvement was significantly more frequent in CD5+ patients than in CD5– patients (67.5% vs 47.2%; P = .048). Mutated immunoglobulin heavy chain variable region gene was more common in CD5+ patients (80.0%) than CD5– patients (64.0%), but this association was not significant (P = .327). Overall survival was calculated until death from any cause, disease-specific survival until lymphoma-related death, and time from diagnosis to first treatment was calculated either considering all interventions or only systemic treatments. None of these outcomes were associated with CD5 expression.
