Correlation between preoperative PCI imaging, intraoperative PCI measurement, and overall survival in peritoneal carcinomatosis secondary to ovarian, tubal, and primary peritoneal carcinoma.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPeritoneal Cancer Index (PCI) is widely used to evaluate peritoneal carcinomatosis before surgery. This study aims to assess the correlation between preoperative and intraoperative PCI. The secondary objectives were determining whether PCI could predict surgical oncologic outcomes and overall survival.
methodWomen with advanced-stage epithelial ovarian cancer, primary peritoneal cancer, or fallopian tube cancer who underwent primary cytoreductive surgery or interval debulking were included. The preoperative computerized tomography (CT) scan findings and intraoperative measurement of the peritoneal carcinomatosis were evaluated using PCI, and their correlation was determined using the Spearman coefficient. The overall survival was calculated using the Kaplan-Meier method.
results52 patients were eligible and analyzed. Mean preoperative and intraoperative PCI were 5.04 and 7.27, orderly. Twenty-nine patients achieved optimal surgery (55.8%). A moderate correlation exists between the PCI obtained from the CT image and surgical findings (r = 0.510, P < 0.001). The significant cutoff values of preoperative PCI and intraoperative PCI to predict optimal surgical outcomes could be 7 and 8, respectively. In multivariate analysis, preoperative Cancer Antigen 125 (CA125) < 416 U/mL and intraoperative PCI < 8 were the only independent factors for optimal surgery. The overall survival was significantly improved in patients with an intraoperative PCI score of less than 8(14 to 36 months, p = 0.015).
conclusionThe preoperative PCI from practical imaging within 30 day before surgery would be beneficial as a predictive method to assess the possibility of optimal cytoreduction and the optimal time for surgery.
