Abstract: Primary testicular lymphoma is a rare lymphoid malignancy, most often, histologically, representing diffuse large B-cell lymphoma. The tumor rnicroenvi.ro.nrnent and limited immune surveillance have a major impact on diffuse large B-cell lymphoma pathogenesis and. survival, but the impact on primary testicular lymphoma is unknown. Here, the purpose of the study was to characterize the tumor microenvironme.nt in primary testicular lymphoma, and associate the findings with outcome. We profiled the expression of 730 immune response enes in 60 primary testicular lymphomas utilizing the Nanostring platorm, and used multiplex imrnunohistochemistry to characterize the immune cell phenotypes in the tumor tissue. We identified a gene signature enriched for T-lymphocyte markers differentially expressed. between the patients. Low expression of the signature predicted poor outcome independently of the International Prognostic Index (progression -free survival: HR=2.810, 95%CI: 1.228-6.431, P=0.014; overall survival: HR=3.267, 95`)/0' CI: 1.406-7.590, P=0.006). The T-lymphocyte signature was associated with outcome also in an independent diffuse large B-cell lymphoma cohort (n=96). Multiplex immunohistochemistry revealed that poor survival of primary testicular lymphoma patients correlated with low percentage of CD3'CD4' and CD3+CD8' tumor-infiltrating lymphocytes (P
