B lymphocytes and tertiary lymphoid structures have a prognostic impact on penile squamous cell carcinoma.

ABSTRACT: Several prognostic markers, including tumor-infiltrating lymphocytes, which have been recently identified in penile squamous cell carcinoma (pSCC), have focused mostly on T cells. The prognostic role of B cells and tertiary lymphoid structures (TLSs) has not yet been sufficiently described. We examined whole tissue sections histopathologically for TLSs and immunohistochemically for CD20 and CD138. The B-cell immunoscore (B-IS) divided the cohort into five categories based on the expression of these two B-cell/plasma cell markers (CD20 and CD138, respectively). Patients with fewer TLSs had worse overall survival (OS) [hazard ratio (HR) = 2.17; 95% CI: 0.94-5; p = 0.069]. A significant association was identified between a high TLS diameter and the presence of a lymphocytic infiltrate [odds r
