Advances in the treatment of gastric cancer: 2019

Purpose of review The aim of this study was to review studies published within the past year regarding management of gastric cancer. Recent findings Laparoscopic gastrectomy achieves equivalent survival compared with open gastrectomy in early stage and locally advanced gastric cancer. Adjuvant chemotherapy with 6 months of S-1 and oxaliplatin was superior to 12 months of S-1, and the addition of postoperative radiation therapy did not improve survival. The FLOT regimen is the new standard for preoperative chemotherapy. In metastatic gastric cancer, the addition of docetaxel to S-1 and cisplatin failed to improve overall survival over two-drug chemotherapy. The addition of the immune checkpoint inhibitor pembrolizumab to chemotherapy failed to improve overall survival compared with chemotherapy alone. Summary Laparoscopic gastrectomy is acceptable in early and locally advanced gastric cancer. Combination adjuvant chemotherapy is superior to S-1 monotherapy. Adjuvant radiation therapy after D2 gastrectomy for node-positive gastric cancer does not improve survival. Preoperative chemotherapy with FLOT (5-FU, leucovorin, oxaliplatin and docetaxel) without radiation therapy is the standard treatment in the West. Two-drug chemotherapy is the optimal initial treatment in metastatic disease. Adding pembrolizumab to front-line chemotherapy did not improve survival, with use of immune checkpoint inhibitors reserved to treat chemotherapy refractory metastatic disease.
