Ca125 KELIM as a Potential Tool for Predicting Hyperthermic Intraperitoneal Chemotherapy (HIPEC) Benefit at Interval Cytoreductive Surgery for Advanced Epithelial Ovarian Cancer-A Propensity Score-Matched Analysis.
Observational study in Journal of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveThe aim of the study was to explore the role of KELIM as a potential clinical biomarker to help select patients who would benefit with the addition of Hyperthermic intraperitoneal chemotherapy(HIPEC) at interval cytoreductive surgery following neoadjuvant chemotherapy.
methodsThis was a multi-institutional, retrospective observational study of 265 patients with Stage IIIC and Stage IV A high grade serous epithelial ovarian cancer who had undergone interval cytoreductive surgery following neoadjuvant chemotherapy. Propensity score matching was performed to reduce confounding by indication for HIPEC. Matching variables were age, FIGO stage, surgical PCI, and NACT cycles. Univariable and multivariable cox-regression models were created to assess predictors of survival. Survivals were analysed using Kaplan-Meier curves.
resultsThe median OS and median DFS of patients with Low KELIM score and who received HIPEC was 38 months and 18.9 months respectively as compared to Median OS = NR and DFS of 39.7 months respectively in patients with a high KELIM score who received HIPEC. Patients with low KELIM did worse with the addition of HIPEC (3 year OS-61%, DFS 15%) as compared to patients with High KELIM and HIPEC (3 year OS 90%, DFS- 54%).
conclusionKELIM may help to identify patients who are likely to benefit from the addition of HIPEC at interval cytoreductive surgery. However, these findings require validation in larger prospective studies.
