Conditional Survival After Cytoreductive Surgery with Heated Intraperitoneal Chemotherapy for Low- and High-Grade Appendiceal Primaries

Introduction Survival of patients after cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy for appendiceal neoplasms is projected by conventional overall survival (OS) curves that do not address the survival time a patient has already accrued. We sought to study the conditional survival (CS) after CRS, contingent on patients surviving a fixed duration of time after surgery.
