ABSTRACT
PURPOSE:
For treatment of esophageal carcinoma, the optimal postoperative radiotherapy target volume after three-field lymph node dissection (3-FLD) had not been determined. We analyzed local recurrence pattern of thoracic esophageal carcinoma and risk factors of lymph node recurrence after 3-FLD without prophylactic radiotherapy. MATERIAL ANDMETHODS:
We reviewed 1282 patients with thoracic esophageal squamous cell carcinoma (ESCC) who were treated with 3-FLD without radiotherapy from 2010 to 2018 and analysed local recurrence patterns and risk factors of lymph node recurrence, in order to provide a reference for determination of the radiotherapy target volume for thoracic ESCC.RESULTS:
The lymph node recurrence accounted for 91.0% of treatment failures. The mediastinal, cervical and abdominal lymph node recurrence accounted for 84.92%, 36.07% and 22.30%, respectively (χ2=264.776, P=0.000). The superior, middle and inferior mediastinal lymph node recurrence rates were 67.54%, 27.87% and 0.98%, respectively (χ2=313.600, P=0.000). Cervical metastases were significantly associated with N stage and Preoperative cervical lymph node status. Abdominal metastases were significantly associated with the number of preoperative abdominal lymph node metastases (LNM), tumor location and N stage.CONCLUSIONS:
The main pattern of local-regional recurrence might be lymph node metastasis after radical 3-FLD without radiotherapy in esophageal carcinoma. The dangerous lymph node recurrence regions included neck, superior and middle mediastinum. The abdominal areas might be irradiated for lower TEC patients with preoperative abdominal LNM.Palavras-chave
