Fig 1 The prospective study process. Group A patients underwent cervical lymph node (LN) dissection because they were diagnosed as having upper mediastinal LN metastasis by intraoperative diagnosis. Group B patients received cervical LN dissection with randomized selection. Group C patients did not receive cervical LN dissection with randomized selection. (ESCC = esophageal squamous cell carcinoma.) The Annals of Thoracic Surgery , DOI: ( /j.athoracsur ) Copyright © 2005 The Society of Thoracic Surgeons Terms and Conditions

Fig 2 Results of intraoperative detection of thoracic paratracheal lymph node (LN) metastasis and metastatic status in cervical lymph nodes. Cervical LN metastasis was detected by conventional hematoxylin and eosin staining and real-time reverse transcription-polymerase chain reaction. Cervical LN recurrence was followed up by commonly used diagnostic techniques, such as computed tomography and ultrasonography.
