How long can I live after gastric cancer surgery? This is a question that stomach cancer patients and their family members are very eager to know. What can be explained is that with treatment, there is a significant effect on prolonging the life of stomach cancer patients. Patients who have undergone surgery for gastric cancer can usually live about 5 years longer. After medical observation, it was found that patients with advanced gastric cancer were grouped together, one group had surgery only, and one group took 5-fluorouracil and folinic acid after radiotherapy. The surgery patients survived an average of 27 months and the radiotherapy patients survived an average of 42 months. after 3 years, 52% of the radiotherapy patients were still alive and only 41% of the surgery only patients survived. Radiotherapy did have side effects, with half of the patients having decreased red and white blood cells and 33% having gastrointestinal problems such as diarrhea. Three patients died, but this was not unexpected or very unreasonable given the severity of the patient’s condition and the few other treatment options available. In the near future, researchers hope to explore the effects of chemotherapy given to patients before surgical gastric resection, and they will study new chemotherapy drugs such as gemcitabine, which makes patients more sensitive to radiation therapy. Factors that affect survival time after gastric cancer surgery: First, the duration of treatment. As long as it is a malignant tumor, postoperative survival mainly depends on whether it is treated early or not. However, for most tumors, the early stage can be generally asymptomatic, and they are usually in the middle to late stage when discovered. If the cancer is found by census, it is often early, which is helpful to improve the survival rate of patients after surgery. Therefore, after the age of 45, it is better to check the body 1-2 times a year if possible. Secondly, the mindset of patients after gastric cancer surgery is also important. Patients should not be disturbed by the question of how long to live, and maintaining a peaceful mood to actively cooperate with the surgery treatment will have a positive impact on the survival time after surgery. Besides, how long a patient can live after gastric cancer surgery is also related to the patient’s physical function to a certain extent. A good physical function and strong immunity can resist the development of cancer and tolerate various drug treatments. Therefore, it is important for gastric cancer patients to improve their immune function and strengthen their resistance to tumor. In addition, whether the treatment method is appropriate, whether the surgery is thorough and whether the treatment measures are timely largely affects how long a patient can live with gastric cancer surgery. According to the patient’s pathological stage of cancer and physical condition, the most suitable surgical treatment can be selected in time to eradicate the tumor, which can prolong the survival time after surgery. Radiotherapy should be performed after gastric cancer surgery! Since the local regional recurrence rate of tumor after radical surgery for gastric cancer is as high as 80%, several gastric cancer treatment collaborative groups have conducted clinical trial studies for postoperative adjuvant radiotherapy. In recent years, most of the phase III clinical trials of postoperative adjuvant radiotherapy have used concurrent chemotherapy and radiotherapy for sensitization, but there are few data from phase III clinical trials of postoperative radiotherapy alone. In an earlier phase III clinical trial completed by the British stomach cancer group, 436 patients with gastric adenocarcinoma were randomized and given radical surgery, postoperative adjuvant external irradiation or adjuvant chemotherapy, respectively. The results of the trial showed no difference in overall survival between the three treatment groups, but the postoperative radiotherapy group had a significantly lower rate of local tumor recurrence compared to the other two treatment options (30%:54%). The analysis of retrospective trials similarly showed that postoperative radiotherapy significantly reduced the local tumor recurrence rate. The effect of postoperative radiotherapy was particularly pronounced in cases with plasma layer infiltration (13) or regional lymph node metastases (nl -3). However, adjuvant external irradiation was not effective in improving patient survival or prolonging survival compared with other adjuvant treatments or postoperative observation. Radiotherapy to the tumor bed to remove residual tumor cells. Although the results of several retrospective clinical trials have shown that intraoperative radiotherapy significantly reduces the rate of local regional tumor recurrence after gastric cancer surgery, the results of a randomized clinical trial originating in Germany showed that intraoperative radiotherapy did not contribute to the prognosis of gastric cancer patients. The trial randomized 115 patients with surgical margin-negative gastric adenocarcinoma to intraoperative radiotherapy or observation. The dose of intraoperative radiotherapy was 28 gy (done in a single session) and was directed only to the celiac axis (abdominal trunk lymphatic area). The trial did not report a difference in local tumor control between the two groups, but the overall survival rate (29.40/0) and mean survival (26.9 months) were slightly lower in patients treated with intraoperative radiotherapy than in the observation group. Based on the results of these trials, single radiotherapy is not recommended as a routine postoperative adjuvant treatment at this time. How long can patients live after gastric cancer surgery? Through the above introduction, we hope that patients and their family members have a certain understanding of the postoperative survival time of gastric cancer patients, and it is also very necessary for patients to undergo postoperative rehabilitation, which plays a very important role in prolonging the life of gastric cancer patients.
