Comparative Effectiveness of Lymphadenectomy Strategies During Curative Resection for Gastric Adenocarcinoma

The purpose of this study was to compare the long-term effectiveness of three lymphadenectomy strategies in patients with gastric cancer. We hypothesized that, compared with the traditional standard (D2) lymph node dissection strategy, the less aggressive modified standard (mD2) lymphadenectomy may offer superior effectiveness due to reduced operative morbidity and comparable long-term recurrence-free survival.
