Prognostic Indicators for Mucinous Appendiceal Neoplasm Patients

Identification of reliable prognostic indicators for different groups of appendiceal mucinous neoplasm patients revealed the Completeness of Cytoreduction (CC) score as a consistent predictor of survival. The Peritoneal Cancer Index (PCI) showed significance in specific subtypes, while the Prior Surgical Score (PSS) predicted outcomes in certain patient groups. Symptomatic patients or those with extensive systemic chemotherapy before cytoreductive surgery had reduced survival. Prognostic indicator utility varied among histologic subtypes, highlighting the importance of proper patient selection.
