Stenting for stomach cancer may result in shorter survival time, about 6-12 months, but some patients may also live longer, it is hard to say. Usually, if the diagnosis of gastric cancer is clear, it should be treated by surgery as far as possible, and stenting may be a palliative treatment for the tumor at a later stage when it cannot be operated, for example, if the tumor is in the cardia or pylorus, which may lead to obstruction of eating or gastric retention, and the patient is not able to eat, and the stenting treatment can solve the problem of obstruction, and the patient can eat after the operation, but the tumor will continue to grow and may grow up to the size of a stent again. However, after a long time, the tumor will continue to grow and may grow into the middle of the stent or inside the stent again, forming obstruction again. The patient’s condition may be relatively late, so the survival time should be relatively short, but after stenting, if the patient’s obstruction problem is relieved, and if the tumor shrinks with chemotherapy or targeted therapy, the patient can consider reoperation.
