ABSTRACT
BACKGROUND:
Patients in whom endoscopic submucosal dissection (ESD) has resulted in noncurative resection need further surgical treatment. However, the oncologic outcome of additional gastrectomy after ESD compared with surgery alone remains unclear.METHODS:
The clinical data of 778 patients who underwent gastrectomy for early gastric cancer (EGC) from January 2008 to December 2019 in Ishikawa Prefectural Central Hospital were retrospectively analyzed. Of these 778 patients, 187 underwent additional gastrectomy after ESD [ESD (+) group] and 591 underwent surgery alone [ESD (-) group]. We compared the overall survival and disease-free survival between the ESD (+) and ESD (-) groups, using propensity score matching (PSM) to adjust for baseline characteristics. We also assessed early postoperative outcomes.RESULTS:
After PSM based on sex (male or female), age, tumor diameter, tumor gross type, and operative procedure, each group comprised 144 patients with no significant differences in clinical background characteristics. After matching, the 5-year overall survival rate in the ESD (+) and ESD (-) group was 90.9% and 87.8%, respectively, with no significant difference (P = .470). In addition, there was no significant difference in the disease-free survival rate (97.6% vs 95.8%, respectively; P = .504). The postoperative complication rate was similar in both groups.CONCLUSION:
Additional gastrectomy for patients in whom ESD resulted in noncurative resection did not adversely affect the long-term prognosis. Additional gastrectomy after ESD is oncologically acceptable for EGC.
