BCL10 expression is unrelated to clinico-pathological parameters or prognoses for oral squamous cell carcinomas

BCL-10 (B-cell lymphoma 10) has been linked to a pro-apoptotic gene in mucosa-associated lymphoid tissue (MALT) lymphomas. We describe the expression of BCL10 in oral squamous cell carcinoma (OSCC) and its relation to clinical, pathological and prognostic parameters. We carried out a retrospective study of 50 patients in Spain who were diagnosed with OSCC. We constructed a tissue microarray of the samples to study the expression of BCL10 using immunohistochemistry. Diffuse and homogeneous staining was observed in the nuclei and cytoplasms of most neoplastic cells of the vast majority of tumors and no significant differences were seen in different areas of the tumors. The expression was unrelated to any clinical or pathological parameters including tumor stage. The intra-class coefficient was 0.97, which indicates the minimal variability among the determinations.
