Purpose: The surgical or endoscopic resection is the current treatment modality for 2– 5 cm gastric gastrointestinal stromal tumors (GISTs). However, evidence is lacking as to which treatment modality is better. Our objective is to provide a new reference for the standardization of the treatment of 2– 5 cm gastric GISTs.
Patients and Methods: A retrospective study was conducted on 177 patients who underwent resection for 2– 5cm gastric GISTs between January 2007 and July 2019 at Xiangya Hospital of Central South University. The cases were divided into surgical group (n=118) and endoscopic group (n=59). The clinical data, pathological and genetic characteristics, short- and long-term outcomes were compared.
Results: Symptoms showed more obvious in the surgical group including abdominal pain and bleeding. In the endoscopic group, tumor size was smaller (p< 0.001), and risk classification was lower (p< 0.001). Patients in the endoscopic group had shorter anal exhaust time (p< 0.001) and lesser hospital cost (p< 0.001). However, the incidence rate of complications (25.42 vs 4.20%; p< 0.001) and reoperation (22.03 vs 0.00%; p< 0.001) in the endoscopic group was relatively higher than these in the surgical group. There was no significant difference in recurrence-free survival or overall survival between two groups.
Conclusion: Gastric GISTs of 2– 5cm may be suitable to select laparoscopic surgery.
