When patients with esophageal cancer vomit blood, generally speaking, the effect of treatment varies greatly according to the amount of vomiting blood. If the amount of vomiting blood is small, it often indicates that the tumor cells only invade the mucosa or submucosa layer of esophagus. At this time, if the general condition of the patient is good, it is recommended to remove the tumor by surgery as soon as possible, and the combination of chemotherapy and radiotherapy after surgery can achieve better treatment effect. If the patient has a large amount of bleeding, it often indicates that the tumor has invaded the whole layer of esophagus and corroded to the surrounding larger blood vessels. At this time, even if the tumor is removed and combined with chemotherapy and radiotherapy, the cancer cells inside the blood vessels cannot be completely removed, and the patient’s prognosis is relatively poor and the probability of recurrence is very high.
