ESCC Esophageal squamous cell carcinoma, TMTV Total metabolic tumor volume, pathological LNMs Pathological lymph node metastases, MR Medical reason
PET-N-positive ¹⁸F-FDG uptake on PET observed in lymph nodes within a three-field region, including
M1LYM of the supraclavicular, cervical paratracheal and celiac artery lymph nodes
A: TMV < 3.82 SA and SMR B: TMTV≥3.82 SA C: TMTV≥3.82 SMR
SA Surgical resection alone, SMR Surgical resection without NAC due to several medical reasons
