Influence of Hormone Treatment in Radiation Therapy for Bladder Cancer
Study Overview
Status
Intervention / Treatment
Detailed Description
Bladder cancer (BC) is one of the most frequent cancers in the world and more common in men than female. Gender-related factors may be involved in the pathogenesis of BC.
Studies have suggested that androgen-receptors may be present in the bladder and potentially involved in BC aetiology, thus making BC susceptible for androgen deprivation therapy (ADT).
Currently treatment for BC includes surgery or radiation therapy. ADT include Degarelix, which besides decreasing testosterone, has been shown to reduce the occurrence of BC in rats and promote stem cell recovery following radiation therapy.
Hypothesis ADT will lower the incidence of BC, and the prognosis of BC will vary depending on the type of ADT used. Furthermore Degarelix administered during radiation therapy for BC will reduce the degree of fibrosis in the bladder thus decreasing adverse side effects.
Methods A cohort of patients treated with ADT for PC will be compared to two cohorts of age-matched men with and without PC both without ADT. The incidence of BC will be recorded for every group. Furthermore the cohort of patients with PC and ADT will be divided into subgroups, depending of the type of ADT they have received and the degree of deprivation. They will be compared in terms of incidence and prognosis of BC.
Finally, a small pilot study will be conducted to investigate the effect of Degarelix when administered during radiation therapy for BC.
Perspectives This will be one of the largest studies to investigate the potential influence of sex hormones in the development and prognosis of BC and potentially lead to new treatment options and possibly a new way of reducing radiation side effects.
