Δ-Peritoneal Cancer Index (Δ-PCI) to Predict Complete Cytoreduction and Histopathological Response to Neoadjuvant Chemotherapy in Ovarian Cancer.

To analyze the role of PCI variation (Δ-PCI) before and after neoadjuvant chemotherapy (NACT) in an interval cytoreductive surgery (ICS) setting with the aim to propose a scoring model for predicting both complete cytoreduction and histopathologic response. A total of 50 consecutive patients who underwent ICS at our institution were prospectively collected between January-2020 and December-2023. PCI was assessed at exploratory surgery and at ICS.
