BACKGROUND AND STUDY AIMS: The aim of this retrospective study was to evaluate the impact of endoscopic ultrasound (EUS)-guided biopsy in patients with esophageal carcinoma where distant lymph nodes which were possibly metastatic were visualized using EUS. PATIENTS AND METHODS: Out of 198 patients (150 men, mean age 66 years) examined over a 4-year period by EUS for local staging of esophageal cancer (121 squamous cell carcinomas and 77 adenocarcinomas), there was EUS visualization of distant lymph nodes in 40 (20%). EUS-guided biopsy was carried out in the latter patients, of cervical nodes with mediastinal tumors (n = 19), of celiac nodes with cervical tumors (n = 2) or superior mediastinal tumors (n = 9), and upper mediastinal lymph nodes in the case of distal adenocarcinomas (n = 10). RESULTS: On EUS-guided biopsy, results were positive in 31 patients, eight were correctly negative (as confirmed by surgery), and in one patient there was a technical failure, with positive findings on subsequent surgery. The sensitivity and specificity of the diagnosis of malignant lymph nodes were therefore 97% and 100% respectively. The positive results of EUS-guided biopsy modified the tumor staging in 31 of these cases (77.5%), proving distant lymph node metastasis which is classified as stage M1. With regard to actual clinical management, surgery was withheld from 24 patients (60% of 40 cases) who were then treated with concomitant radiotherapy and chemotherapy. CONCLUSION: EUS-guided biopsy of distant lymph nodes was indicated in 20% of patients with esophageal cancers, and the biopsy results led to upgrading of the tumor stage in about 80% of cases and influenced the treatment decision in about 60%.
