Gastric cancer associated peritoneal carcinomatosis (GCPC) has a poor prognosis with a median survival of less than one year. Systemic chemotherapy including targeted agents has not been found to significantly increase the survival in GCPC. Since recurrent gastric cancer remains confined to the abdominal cavity in many patients, regional therapies like aggressive cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) have been investigated for GCPC. HIPEC has been used for three indications in GC- as an adjuvant therapy after a curative surgery, HIPEC has been shown to improve survival and reduce peritoneal recurrences in many randomised trials in Asian countries; as a definitive treatment in established PC, HIPEC along with CRS is the only therapeutic modality that has resulted in long-term survival in select groups of patients; as a palliative treatment in advanced PC with intractable ascites, HIPEC has been shown to control ascites and reduce the need for frequent paracentesis. While the results of randomised trials of adjuvant HIPEC from western centres are awaited, the role of HIPEC in the treatment of GCPC is still evolving and needs larger studies before it is accepted as a standard of care.
Core tip: Peritoneal carcinomatosis (PC) associated with gastric cancer has a poor prognosis. Systemic chemotherapy is not very effective in this situation and therefore, regional therapies like cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (HIPEC) have been investigated to improve the survival of these patients. HIPEC has been used as an adjuvant after curative resection, in the treatment of established PC and in palliating intractable ascites in gastric cancer. This review looks at the current status of HIPEC in peritoneal metastasis due to gastric cancer.
