First of all, it depends on whether the patient is treated at the best time, whether the preoperative and postoperative care is proper, whether the patient is in a good state of mind, and whether the patient’s physical function is good or bad. The key to ensuring how long a patient can live after a successful surgery is also whether it will recur. If there is no recurrence, the patient can survive for a long time; on the contrary, the patient may only have a few months or years of life left after recurrence. Simply speaking, the factors affecting the efficacy of esophageal tumor surgery are: 1. 2. Regional lymph node metastasis and whether it is completely cleared or not: it is an important factor affecting the efficacy of esophageal tumor, the 5-year survival rate of radical resection is about 50% for those without lymph node metastasis and less than 20% for those with lymph node metastasis. 3. Residual tumor at the cut edge or not: submucosal infiltration of esophageal tumor is one of the characteristics of metastasis, if the residual tumor at the cut edge is infiltrative tumor, there is no survivor for more than 5 years. 4. Pre-operative radiation therapy: For larger tumors, increasing pre-operative radiotherapy can improve resection rate, reduce intraoperative tumor spread and improve survival rate.
