A 70-year-old man with advanced prostate cancer, most of which has undergone localized spread or distant metastasis, needs to be adequately examined to clarify his condition. According to the condition, general treatment, drug treatment, surgical treatment and other therapies can be given. 1. General treatment: It is necessary to take reasonable diet, avoid eating spicy, stimulating and greasy food, exercise regularly and quit smoking and drinking. At the same time, build up confidence and keep a good mindset. 2. Drug treatment: chemotherapy is needed, such as docetaxel, mitoxantrone, etc.; endocrine drug treatment can also be given, such as flutamide, enzalutamide and other androgen antagonists. 3. Surgical treatment: prostate cancer in advanced stage loses the opportunity of surgery, and palliative surgery can be given when necessary. Some patients can be given orchiectomy to reduce the secretion of androgen. 4. Other therapies: such as radiotherapy, which kills cancer cells through high-energy rays, especially for the treatment of metastatic foci. It is suggested that patients should go to the hospital for consultation and complete all auxiliary examinations in order to clarify their conditions, and then professional doctors should give corresponding treatments for their conditions, and medicines should be used under the guidance of professional doctors.
