Predicting Aborted Hyperthermic Intraperitoneal Chemotherapy (AHIPEC) with Preoperative Tumor and Inflammatory Markers in Potentially Resectable Appendiceal Cancer Patients with Peritoneal Carcinomatosis.

Risk factors vary for AHIPEC among low-grade, high-grade, and high-S AC histology. Elevated preoperative CA19-9, CA125, CRP, and previous HIPEC should be considered in the selection process for CRS/HIPEC in low-grade AC, as well as elevated CRP and previous HIPEC in high-grade AC, to avoid unnecessary surgery.
