Abstract
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.
Results: The cohort's median age was 53 years, with a male predominance (58.5%). The median OS was not reached, but the mean OS was 76.87 months. In univariate analysis, several factors, including synchronous organ metastasis, Pathologic Peritoneal Carcinomatosis Index (pPCI) ≥10, increased estimated blood loss, and severe postoperative complications, were associated with worse OS. However, multivariate analysis identified pPCI ≥ 10 as the sole independent predictor of worse OS. The 1- and 3-year survival rates were 83% and 70.4%, respectively. pPCI ≥ 10 and severe postoperative complications were significant predictors of worse survival outcomes.
Conclusions: Radical surgery alone is not enough, and CRS combined with HIPEC and IORT, when indicated, was proven to be safe and effective with no added morbidity or mortality.
