Prognostic impact of positive peritoneal cytology (POPEC) in gastric cancer: Multi-centre European retrospective cohort study

Puntos clave

• Positive peritoneal cytology significantly affects clinical outcomes in gastric cancer, indicating poorer prognosis and survival rates.
• In the analysis of 300 gastric cancer cases, 45% exhibited positive peritoneal cytology, correlating with advanced disease.
• This observational analysis across multiple European centers focused on assessing prognostic factors in gastrically affected individuals.
• Findings highlight the need for further research into diagnostic improvements and treatment strategies for patients with positive cytology.
