Abstrakt: Objective: To investigate the time delay effect from initial diagnosis to endoscopic submucosal dissection on superficial esophageal squamous cell carcinoma curability, considering the preoperative invasion depth.
Methods: This study included superficial esophageal squamous cell carcinoma diagnosed as T1a-epithelial/lamina propria mucosa cancer (cEP/LPM; cancer invading up to the lamina propria mucosa) or cT1a-muscularis mucosa (MM)/T1b-submucosal cancer (cMM/SM1; cancer invading up to 200 µm into the submucosa) and treated using endoscopic submucosal dissection from January 2017 to December 2021. We compared curability in lesions treated within three months (early treatment group) versus those treated ≥7 months post-diagnosis (delayed treatment group). Curative resection criteria included lesions confined within the muscularis mucosae, with negative vertical margins, and with absence of lymphovascular invasion. Non-curative resection included all other cases.
Results: Among the 231 and 75 lesions in the early and delayed treatment groups, respectively, no significant difference was observed in non-curative resections for all lesions and cEP/LPM lesions (early: 194, delayed: 70). Conversely, the proportions were significantly higher in the delayed treatment group than in the early treatment group for cMM/SM1 lesions (early: 37, delayed: 5; p = 0.018).
Conclusions: This study suggests that delayed endoscopic submucosal dissection does not significantly affect cEP/LPM lesions curability but is associated with reduced cMM/SM1 lesions curability. Prompt treatment is important for cMM/SM1, whereas delayed treatment may be acceptable for cEP/LPM.
