Chemotherapy Alone Versus Surgery Plus Chemotherapy for Distal Gastric Cancer With One Non-curable Factor

Sun Yat-sen University120 enrolled

Overview

Our study aims to compare the efficacy and safety of Chemotherapy Alone Versus D2 distal gastrectomy and metastasectomy plus Chemotherapy for gastric cancer (GC) with one non-curable Factor

Gastric cancer is the fourth most common malignancy worldwide and the second leading cause of cancer-related deaths, with the highest mortality rates reported in East Asia, including China. Many patients are diagnosed at an advanced stage of gastric cancer because of late onset and nonspecific symptoms. The prognosis of patients with advanced gastric cancer with non-curable factors, such as hepatic, peritoneal, or distant lymph node metastases, is poor. Chemotherapy is the standard of care for these patients. Palliative resection or bypass surgery is generally indicated in the presence of major symptoms such as bleeding or obstruction for incurable advanced gastric cancer. The usefulness of gastrectomy and metastasectomy is still unclear. The REGATTA trial is the first clinical trial to explore the significance of surgery for incurable advanced gastric cancer. However, it concluded an opposite conclusion that gastrectomy followed by chemotherapy did not show any survival benefit compared with chemotherapy alone in advanced gastric cancer with a single non-curable factor. Interestingly, there was a significant interaction between treatment effect and tumor location in subgroup analyses of overall survival. Gastrectomy plus chemotherapy was associated with significantly worse overall survival in patients with upper-third tumors for less chemotherapy cycles. This finding raises the question whether inclusion criteria were restricted to the patients with lower-third tumor, findings of study might have been positive. So we raise this new trail to assess the significance of Gastrectomy and Metastasectomy for Distal Gastric Cancer With One Non-curable Factor.
