Abstract:
Purpose To explore the mutation of CD79B and MyD88 in primary testicular diffuse large B cell lymphoma and their significance.Methods Histopathologic features were observed in 15 cases of primary testicular diffuse large B cell lymphoma and immunophenotype was analyzed by immunohistochemical staining (IHC).Sanger sequencing was used to detect CD79B Y196 and MyD88 L265 mutation in these cases.The relationship between CD79B,MyD88 mutation and the clinicopathological features was analyzed.Results Immunophenotypically,15 cases were non germinal center B cell type.CD79B (Y196) mutation was detected in 4 cases (26.7％).For MyD88,L265 mutation was found in 7 cases (46.7％).CD79B and MyD88 mutations were found in 3 cases.The followup information was obtained in 8 patients.No association was found between CD79B,MyD88 mutation and outcome of patients.Conclusion Primary testicular diffuse large B cell lymphoma of non germinal center B cell type is a rare aggressive B cell lymphoma with poor prognosis and poor response to chemotherapy.CD79B,MyD88 gene mnutation was detected in Chinese patients with frequency of 26.7％ and 46.7％ respectively.It is possible for molecular targeted therapy of the primary testicular diffuse large B cell lymphoma on the basis of high frequency of CD79B and MyD88 gene mutation.
