Second opinion for husband's stage 4A prostate cancer? And update

My partner was diagnosed with stage 4 A prostate cancer with spread to pelvic lymph nodes. Oncologist has recommended surgery followed by radiation and hormone therapy for a good prognosis. He is 65 healthy and no symptoms. PSA was 11. Has a history of prostrate cancer. Was wondering if we should get another opinion regarding getting surgery first. The dr wants to treat it aggressively. Any advice on what to expect, next steps appreciated.
