CD5 and p53 immunohistochemistry: valuable prediction method in molecular typing of CD5-positive diffuse large B-cell lymphoma.

ABSTRACT:

Background

CD5 positive diffuse large B-cell lymphoma (DLBCL) has unique clinical and pathological characteristics.

Methods

We analyzed 25 cases of CD5-positive DLBCL, focusing on their clinical, morphological, immunohistochemical and genetic features.

Results

Among the 13 females and 12 males, 14 were over 60 years (14/25, 56%). A majority of them presented in stage IV (15/21, 71.43%), primarily with extranodal lesions (14/25, 56%). The positive expression rates of CD20, CD10, BCL6, MUM1, MYC, and BCL2 were 100% (25/25), 40% (10/25), 84% (21/25), 100% (25/25), 87.5% (21/24) and 100% (25/25), respectively. Twenty-one cases (87.5%, 21/24) were MYC/BCL2 double-expressing. More than half of the cases were non-germinal center origin (15/25, 60%). The accuracy of p53 in pr
