Gastric cancer at 83 years of age, according to CSCO guidelines, the best management option is resection for early gastric cancer without lymph node metastasis, and laparoscopic resection after adjuvant chemotherapy for progressive stages. For unresectable patients, palliative care is considered: short-circuit surgery, stenting, or jejunal nutritional tube placement. 1. Early gastric cancer without lymph node metastasis: laparoscopic resection is feasible. The short-term efficacy of treating advanced gastric cancer is satisfactory, and it has the advantages of small abdominal trauma, fast postoperative recovery and short hospitalization time. 2. Progressive gastric cancer: it is necessary to carry out adjuvant chemotherapy before laparoscopic resection. Oxaliplatin, calcium folinate and 5-fluorouracil are the traditional chemotherapeutic regimens, and the interaction of several drugs can improve the effect of killing cancer cells. 3. Unresectable: Consider palliative short-circuit surgery, stenting or jejunal tube placement. The specific option to choose needs to be analyzed by the doctor according to the physical condition of the elderly. If you are suffering from gastric cancer at a senior age, you should actively treat it under doctor’s guidance and don’t stop the treatment, in order to prolong the patient’s life and improve the patient’s quality of life as much as possible. Please strictly follow the doctor’s prescription for medication and do not use medication on your own.
