研究目的: |
项目组前期已进行了局部进展期胃癌新辅助化疗后行腹腔镜远端胃癌D2根治术的单臂临床研究,结果发现新辅助化疗后行腹腔镜远端胃癌根治术是安全可行的(CLASS-03a)。基于此,本项目以局部进展期胃下部腺癌(cT3-4a、N-/+、M0)接受了新辅助化疗后的患者为研究对象,比较在新辅助化疗后实施腹腔镜远端胃癌D2根治术与开腹远端胃癌D2根治术的远期生存结局。 |

|
Objectives of Study: |
Our research team previously conducted a single-arm clinical trial (CLASS-03a) evaluating laparoscopic distal gastrectomy with D2 lymphadenectomy following neoadjuvant chemotherapy for locally advanced gastric cancer, which demonstrated that the procedure is safe and feasible. Building upon these findings, the present study focuses on patients with locally advanced distal gastric adenocarcinoma (cT3–4a, N-/+, M0) who have received neoadjuvant chemotherapy, aiming to compare the long-term survival outcomes of laparoscopic versus open distal gastrectomy with D2 lymphadenectomy in this setting. |
