摘 要：Although the combination of radiation therapy and androgen deprivation therapy (ADT) is initially effective in many patients, biochemical failure rates of 20at 5-years to 50at 10-years have been reported, highlighting the need for improved treatments, particularly for men with high- risk prostate cancer. ADT in the neo-adjuvant setting is used to reduce tumor volume and improve the response to radiation. Additionally, ADT causes infiltration of lymphocytes into the prostate. B cell infiltrates may promote prostate cancer progression and development of castration resistant prostate cancer by the production of inflammatory cytokines and skewing CD4+ T cell responses towards Th2. We hypothesized that depletion of B cells at the time of castration would improve tumor control. Our results demonstrate that the depletion of B cells at the time of castration improves tumor latency.
