[Surgical problems and considerations in conversion treatment of stage IV gastric cancer].

Abstract

The prognosis of stage IV gastric cancer is extremely poor. Due to the diversificationof treatment methods and the rise and popularizationof multidisciplinary treatment(MDT), the conversion therapy for stage IV gastric cancer has been recognized by more and more surgeons, which brings hope to patients with stage IV gastric cancer,. However, stage IV gastric cancer has various forms of metastasis, and the effect of conversion therapy and the prognosis of patients depend on the site of tumor metastasis and the systemic tumor load. Our team has long applied MDT diagnosis and treatment mode to patients with stage IV gastric cancer, performing R0 surgical resection for patients with tumor down staging or distant metastasis control after conversion. We would like to share our team's experiences and some controversial hot topics, focal points and difficult problems.
