- Abstract
To evaluate the clinical value of CT and MRI in the diagnosis of lymph node metastasis of thoracic esophageal cancer, from December 2018 to December 2019, 86 patients with thoracic esophageal cancer who underwent radical resection of esophageal cancer and neck lymph node dissection were analyzed retrospectively. Before operation, CT and MRI were used to evaluate the cervical lymph node metastasis, The pathological diagnosis results of cervical lymph node were compared, and the clinical value of CT and MRI to judge the lymph node metastasis of thoracic esophageal cancer was analyzed. a total of 103 cervical regions and 416 cervical lymph nodes were cleaned in 86 patients, among which 31 patients with lymph node metastasis were found, 39 cervical regions and 48 cervical lymph nodes. According to the postoperative pathological results, of the 86 patients, there were 17 cases in T1 stage, 6 cases (8 neck regions) suggested metastasis; 37 cases in T2 stage, 11 cases (15 neck regions) suggested metastasis; 26 cases in T3 stage, 8 cases (10 neck regions) showed positive lymph node metastasis; 6 cases in T4 stage, 6 cases (6 neck regions) all showed metastasis. The distribution of pathological positive lymph nodes was evaluated by N stage: 6 in N1 stage, 17 in N2 stage and 8 in N3 stage; tumor location: 5 in upper thoracic segment, 16 in middle thoracic segment and 10 in lower thoracic segment. Of the 45 cervical regions with positive cervical lymph nodes, 27 were true positive and 18 were false positive. Of the 41 cervical regions with negative cervical lymph nodes, 37 were true negative and 4 were false negative. In 36 cervical regions with positive cervical lymph nodes, 24 were true positive and 12 were false positive; in 50 cervical regions with negative cervical lymph nodes, 43 were true negative and 7 were false negative. The AUC of CT was 0.849, the sensitivity and specificity were 85.46% and 80.83% respectively; the AUC of MRI was 0.751, the sensitivity and specificity were 76.18% and 72.58% respectively. Preoperative CT and MRI examination of esophageal cancer can help to distinguish lymph node metastasis, and the sensitivity and specificity of CT examination are higher than that of MRI, which can be widely used in clinical.
