Pathological staging of esophageal cancer PT3N1MX means that postoperative pathology of esophageal cancer suggests that the cancer has invaded the fibrous membrane of the esophagus, there are 1~2 metastases in lymph nodes, and distant metastases are not clear. Pathological staging of esophageal cancer is a relatively accurate clinical staging, which can clarify the invasion range and depth of the primary lesion of esophageal cancer, and the regional lymph node metastasis is also relatively accurate, but it needs to be clarified by other examinations such as CT, MRI, and so on, in order to clarify the situation of distant metastasis. Pathological staging of esophageal cancer is of great value in guiding the choice of treatment strategy, but such staging can only be obtained through esophageal cancer resection surgery. Patients who are self-conscious of the discomfort should seek medical treatment as early as possible so as to avoid delaying the condition.
