Pancreatic cancer in the middle and late stages needs to seek medical treatment in time, and follow the doctor’s instruction to take surgical treatment, radiotherapy, targeted drug therapy, immunotherapy and supportive therapy to improve the symptoms. 1. Surgery: Pancreatic cancer patients who can tolerate surgery can undergo radical surgery to remove the localized lesion completely. If the tumor tissue cannot be completely removed in the advanced stage, palliative surgery can also be accepted, which can reduce the local burden. 2. Chemotherapy: if the cancer cells continue to spread, chemotherapy with drugs such as albumin paclitaxel, gemcitabine and Tegretol capsules should be used according to the doctor’s prescription, which can control the continued spread of the cancer cells and achieve the purpose of improving the quality of life. 3. Radiotherapy: it can increase the local control rate of tumor. Stereotactic radiotherapy and proton heavy ion radiotherapy with X-ray are commonly used, which are expected to improve the therapeutic effect. 4. Targeted drugs and immunotherapy: Erlotinib is often used in combination with chemotherapy, and pembrolizumab is often used in immunotherapy, which has certain efficacy for patients with indications. 5. Supportive treatment: if the condition is serious in the advanced stage, the nutrients needed by the body can be satisfied by inputting nutrient solution. After diagnosed with pancreatic cancer, patients need to receive standardized and orderly treatment.
