Abstract:
Esophageal squamous cell carcinoma (ESCC) is known for its rapid progression and poor outcomes. China has the highest incidence and mortality in the world. Diagnoses made at early stages and accurate staging are associated with better outcomes, all of which can play a significant role in the selection of treatment protocols. ESCC is staged according to the widely accepted TNM system. Common imaging modalities used in staging ESCC before treatment include endoscopy, computed tomography (CT), positron emission tomography (PET) and magnetic resonance imaging (MRI). Endoscopic ultrasound is useful for staging tumor depth and nodal status. Narrow band imaging is valuable for early stage disease assessment. CT and PET provide additional valuable information regarding node and metastasis staging. The ability of MRI to delineate ESCC is continuously being improved and adds information regarding locoregional status to routine examinations.
