SURGICAL TREATMENT IN CLINICAL STAGE IV GASTRIC CANCER: A COMPARISON OF DIFFERENT PROCEDURES AND SURVIVAL OUTCOMES

ABSTRACT - BACKGROUND: Even in clinical stage IV gastric cancer (GC), surgical procedures may be required to palliate symptoms or in an attempt to improve survival. However, the limited survival of these patients raises doubts about who really had benefits from it. AIM: This study aimed to analyze the surgical outcomes in stage IV GC treated with surgical procedures without curative intent. METHODS: Retrospective analyses of patients with stage IV GC submitted to surgical procedures including tumor resection, bypass, jejunostomy, and diagnostic laparoscopy were performed. Patients with GC undergoing curative gastrectomy served as the comparison group. RESULTS: Surgical procedures in clinical stage IV were performed in 363 patients. Compared to curative surgery (680 patients), stage IV patients had a higher rate of comorbidities and ASA III/IV classification. The surgical procedures that were performed included 107 (29.4%) bypass procedures (partitioning/gastrojejunal anastomosis), 85 (23.4%) jejunostomies, 76 (20.9%) resections, and 76 (20.9%) diagnostic laparoscopies. Regarding patients’ characteristics, resected patients had more distant metastasis (p=0.011), bypass patients were associated with disease in more than one site (p
