BACKGROUND: Positive peritoneal cytology (Cyt+) even in the absence of macroscopic disease is associated with poor prognosis in patients with gastric cancer and deemed as M1 disease. Recent years have seen advancements in the evaluation strategies for peritoneal washings and management of patients with Cyt+. The aim of this review was to describe the newest paradigms in the management of patients with gastric cancer who have Cyt+ without macroscopic peritoneal metastases.
METHODS: A comprehensive literature review was performed to identify studies on the management of gastric cancer and thereby to summarize relevant information on the accuracy of various diagnostic tests and controversies involved in the treatment of patients with Cyt+.
RESULTS: Although conventional cytology remains the standard technique for assessment of peritoneal washings, it is limited by low sensitivity. The role of immunohistochemistry and molecular techniques for the assessment of peritoneal washings is evolving. Although systemic chemotherapy remains the standard of care for patients with Cyt+ disease, the role of gastrectomy, intraperitoneal chemotherapy, extensive intraperitoneal saline lavage, and hyperthermic intraperitoneal chemotherapy is being evaluated.
CONCLUSIONS: Clinical decision-making in patients with Cyt+ remains controversial given the seemingly technical resectable albeit biologically unresectable or aggressive disease that portends an overall poor prognosis. Current management strategies are evolving, and further studies are needed to develop an optimal treatment strategy for these patients.
