If patients have lymph node metastasis of esophageal cancer, there are main treatments such as preoperative adjuvant radiotherapy, surgical treatment and postoperative adjuvant radiotherapy. 1. Preoperative adjuvant radiotherapy: patients can usually undergo adjuvant chemotherapy, radiotherapy or synchronous radiotherapy before undergoing surgical treatment, which can shrink the lesion and better remove the lesion. 2. Surgical treatment: surgical resection treatment should expand the scope of lymph node dissection, and the specific treatment modality and surgical treatment pathway should be related to the size and location of esophageal tumors, patient’s physical condition, lymph node metastasis and other factors. 3. Postoperative adjuvant radiotherapy: it is the adjuvant treatment for patients with residual lesions after surgical resection, which has a good preventive effect on lymph node metastasis and tumor recurrence. Generally, the treatment plan adopts three-dimensional conformal radiotherapy combined with fluorouracil and cisplatin or paclitaxel and cisplatin synchronous chemotherapy. When lymph node metastasis of esophageal cancer occurs, one should seek medical treatment in time.
