Overall survival and prognostic factors associated with cytoreductive surgery and hyperthermic intraperitoneal chemotherapy combined with intraoperative radiation therapy in patients with advanced abdominopelvic malignancies: A single center retrospective analysis of 159 patients.

Background And Objectives: The aim of this study was to look at the overall survival (OS), progression-free survival (PFS), and prognostic factors associated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) combined with intraoperative radiation therapy (IORT).

Methods: This study is a single center retrospective study performed on 159 patients who underwent treatment with CRS and HIPEC combined with IORT for abdominopelvic malignancies. OS and PFS were used to evaluate the efficacy of this treatment strategy amongst patients with abdominopelvic malignancies.
