摘要

AIM To verify the current status of super-extended lymph node dissection for advanced gastric cancer according to a questionnaire survey.METHODS One-hundred and five institutions responded to the questionnaire.The survey included the following items: Number of experiences,whether performed prophylactically and/or therapeutically,whether preoperative chemotherapy was provided,number of preoperative chemotherapy rounds,and therapeutic options after chemotherapy.RESULTS Eighty-seven of the 105 institutions(83%) had performed D3 gastrectomy in the past or continued to perform D3 gastrectomy at present.However,D3 gastrectomy was rarely performed prophylactically in clinical practice.Seventy-eight institutions(74%) indicated that preoperative chemotherapy with curative intent was required for patients suspected of having para-aortic node(PAN) metastases.After chemotherapy,a D3 gastrectomy was scheduled for patients with a complete or partial response,stable disease,and progressive disease at 36(46%),28(36%),and 13(17%) of the institutions,respectively.CONCLUSION For patients with apparent PAN metastasis,a D3 gastrectomy is typically planned if a few courses of preoperative chemotherapy yield at least a stable disease condition.
