It is recommended to go to regular hospital for active treatment of gastric cancer and pancreatic adhesion, and choose targeted therapy and chemotherapy according to the situation. The combination of gastric cancer and pancreatic adhesion usually suggests that the tumor has invaded adjacent tissues or organs, which indicates that it is in the middle or late stage; if it is combined with regional lymph nodes or distant metastasis, then it has already entered the advanced stage. At this time, treatment mainly includes palliative surgical resection, radiotherapy and targeted/immunotherapy. 1. For some patients with obvious symptoms and good health, palliative partial or total gastrectomy combined with adjuvant therapy (chemotherapy, etc.) is feasible to control primary foci and metastatic foci, thus improving the quality of life and prolonging the survival period; 2. for patients who have obvious symptoms but cannot or refuse surgical treatment, they can receive interventional therapy, diversionary surgery or other surgeries (gastrojejunostomy, etc.) in order to improve their quality of life; 3. For patients with advanced gastric cancer who cannot be operated, comprehensive treatment based on drug therapy can be adopted, and some of them can achieve tumor downstaging so as to get the chance of operation, or improve the quality of survival and prolong the survival period. Its drug treatment program is as follows: Paclitaxel-based three-drug chemotherapy, anti-angiogenesis targeted drug combined with chemotherapeutic drug, chemotherapy + anti-Her-2 targeted drug + anti-PD-1 monoclonal antibody four-drug combination therapy (for advanced Her-2-positive patients) and so on. In addition, it is recommended to improve the patient’s nutritional status, control complications and comorbidities, and so on. It is recommended to go to a regular hospital to evaluate the condition and follow the doctor’s instructions to cooperate with the treatment, do not use drugs or treatment on your own.
