This study will divide patients into two sections, and eligible patients will be enrolled. Patients with locally advanced prostate cancer or oligometastatic prostate cancer were assigned to either fasudil hydrochloride and PD1 inhibitor combined androgen deprivation therapy or placebo combined androgen deprivation therapy based on a computer-generated random sequence. In addition to routine androgen deprivation therapy, patients in the treatment group were given 10mg of fasudil hydrochloride on the 1st to 5th day and PD-1 monoclonal antibody (triprilizumab, 3mg/kg, intravenous drip) on the 5th day. In the placebo group, the same size, color and dosage form of 0.9% sodium chloride injection was used, and the administration was the same as that in the treatment group. After starting the intervention, all patients should be followed up in our hospital every treatment cycle to review blood PSA and other indicators. At the end of the treatment cycle, imaging examinations were followed up and radical prostatectomy was performed 3 weeks later (±7 days).
