Prognostic Significance of F-18-fluorodeoxyglucose Positron Emission Tomography (FDG-PET)-Positive Lymph Nodes Following Neoadjuvant Chemotherapy and Surgery for Resectable Thoracic Esophageal Squamous Cell Carcinoma

摘要

Patients with resectable thoracic esophageal squamous cell cancer (TESCC) and positron emission tomography (PET)-positive lymph nodes (PET-N positive) are likely to have a parts per thousand yen3 pathological lymph node metastases (pLNMs) and show a higher rate of postoperative recurrence despite curative resection than PET-N-negative TESCC patients. We examined the prognostic significance of F-18-fluorodeoxyglucose uptake into lymph node metastases after neoadjuvant chemotherapy (NAC) for PET-N positive TESCC and aimed to propose the optimal NAC response criteria for these patients.
