Comparison of Local Recurrence Patterns of Postoperative Radiotherapy with Surgery Alone for Esophageal Carcinoma Patients

Background: We analyzed local regional recurrence patterns of thoracic esophageal carcinoma after three-field lymph node dissection (3-FLD) with and without postoperative radiotherapy, assessed the radiation value for control. Methods: The study reviewed 239 recurrences squamous cell 3-FLD from 2010 to 2018 in our hospital, retrospectively, compared between surgery followed by radiotherapy (S+RT) alone (SA). Results: In carcinomas that underwent curative surgery, was most common type patients both groups. sequence rate groups highest lowest mediastinal, cervical, abdominal. superior mediastinal significantly higher than (67.72% vs. 47.54%, x2 = 7.615, P 0.006). abdominal upper TEC lower middle (x2 9.452, 0.009). preoperative LNM very (43.63% 6.66%, < 0.001). Conclusions: dangerous regions included superior, mediastinum, neck. Postoperative shows great reducing rate. segment metastasis, especially para-aortic may be risk factors recurrence.
