CD20+ Tumor Infiltrating B Lymphocyte in Oral Squamous Cell Carcinoma: Correlation with Clinicopathologic Characteristics and Heat Shock Protein 70 Expression.

Objective: B lymphocyte infiltration in the tumor microenvironment has been proposed to play pivotal roles in tumor progression. Heat shock protein 70 (HSP70) expressed by tumor cells can induce antitumor immune response. Few studies have examined the clinicopathologic relationship between tumor infiltrating B lymphocyte and HSP70 expression in human cancer. So far, there is no complete knowledge on the relationship in oral squamous cell carcinoma (OSCC). The present study was conducted to evaluate the relationship between tumor infiltrating B lymphocyte and HSP70 expression in OSCC, as well as the clinical outcome.

Materials and Methods: In this retrospective study, the immunohistochemical analysis of 50 OSCC specimens was performed using CD20 and HSP70 antibodies. The relationship between markers' expression and clinicopathologic data was evaluated using Mann-Whitney test, Chi-square test, logistic regression model, and Spearman's correlation coefficient.

Results: The data analysis showed significant correlation between peritumoral CD20+ B lymphocyte infiltration and lymph node metastasis ( P = 0.047). Furthermore, HSP70 expression was significantly correlated with stage ( P = 0.003), lymph node metastasis ( P < 0.001), and tumor size ( P = 0.044). However, no relationship was observed between B lymphocyte infiltration and HSP70 expression.

Conclusion: The results suggest that peritumoral B lymphocyte infiltration and HSP70 expression level have significant association with OSCC and may be considered as prognostic indicators in OSCC. Thus, evaluation of B cells as therapeutic targets in OSCC patients is recommended.
