About this trial
The goal of this clinical trial is to learn if Disitamab Vedotin combined with Bicalutamide works to treat advanced HER2-positive and AR- positive extramammary Paget disease of the scrotum. It will also learn about the safety of this combination. All patients received Disitamab Vedotin every 2 weeks and Bicalutamide everyday. Follow-up was conducted until disease progression, intolerable adverse reactions occur withdrawal of informed consent by the subject, loss to follow-up, or death. Clinical tumor imaging assessments were performed using RECIST during the treatment process.
