| Abstract: |
Peritoneal carcinomatosis of gastric origin is an aggressive tumor entity. Historically it has been considered a terminal disease with no long-term survival, due to limited therapeutic options. However, as a better understanding of tumor biology has evolved in recent years, novel multimodal treatment strategies incorporating intraperitoneal (IP) chemotherapy-hyperthermic intraperitoneal chemotherapy (HIPEC), early postoperative intraperitoneal chemotherapy (EPIC), neoadjuvant intraperitoneal-systemic chemotherapy protocol (NIPS)-and cytoreductive surgery (CRS) have demonstrated promising oncologic outcomes and even long-term survival in selected patients. Most of the studies published to date are retrospective in nature. These studies involve heterogenous patient populations, a wide variety of chemotherapeutic drugs, and show wide variation in outcomes between institutions. Thus, it is difficult to evaluate the results. This review summarizes our current knowledge regarding IP chemotherapy and CRS for peritoneal metastases (PM) in gastric cancer (GC). We describe our institutional treatment regimens. We also provide a brief overview of new, targeted therapies that may show promise in the future. © 2021 AME Publishing Company.
