Peritoneal Carcinomatosis Index (PCI) is used to assess the extent of peritoneal cancer by dividing the peritoneal cavity into 13 well-defined regions and assessing the size of the largest tumour nodule in each region. Aim: To evaluate the imaging features of peritoneal carcinomatosis using Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) and correlate it with diagnostic laparotomy. Also to To determine the prognostic significance of peritoneal carcinomatosis index calculated radiologically in predicting the outcome of advanced ovarian malignancies. Materials and Methods: This was a prospective cohort study conducted in Kilpauk Medical College, Chennai, Tamil Nadu, India, from July 2019 to December 2020. Total of 50 females between 18-80 years of age with advanced ovarian malignancies with peritoneal deposits underwent CT and MRI to calculate initial PCI. Then these patients underwent cytoreductive debulking after which final response was assessed. Followedup for a period of 1 year to assess the treatment response and to look for any complications. IBM Statistical Package for the Social Sciences (SPSS) version 22.0 software was used for statistical analysis. Descriptive analysis was carried out using mean and standard deviation for quantitative variables. Results: Fifty women were included with a mean age of 53.4 years. PCI calculated using CT and MRI showed strong correlation with laparoscopic PCI with correlation coefficient (r) of 0.984 and 0.988 respectively with a statistically significant p-value 15 were at a higher risk for developing various complications. Conclusion: Radiological PCI strongly correlate with laparoscopic PCI and is a very strong predictor of disease outcome in advanced ovarian malignancies. It was found that patients with high PCI values had poor response to cytoreductive surgery and chemotherapy. So, high initial PCI values above 11 was indicative of poor patient prognosis.
