Potential biomarkers for predicting the efficacy of a pembrolizumab-containing regimen in advanced cervical cancer: A real-world analysis.

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
Objective: Prognostic biomarkers in patients with advanced cervical cancer treated with immune checkpoint inhibitors remain unclear. An evaluation of combined positive score (CPS) and tumor proportion score (TPS), and a comparison of their usefulness with inflammatory biomarkers in real-world data could be informative. Materials and Methods: We analyzed 28 patients who were treated with the KEYNOTE-826 regimen between November 2022 and June 2024. The complete cohort (group 1), patients with no prior chemotherapy (group 2), and treatment-naïve (group 3) were evaluated as follows: 1) CPS, TPS, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and hemoglobin, albumin, lymphocyte, and platelets (HALP score) in peripheral blood samples were obtained prior to initial treatment and KEYNOTE-826 regimen, and receiver operating curve analysis was used to compare them. The optimal cut-off values that showed the highest level of discrimination for progression-free survival were identified. Results: The areas under the curve (AUC) for progression-free survival in group 2 were measured for CPS, TPS, NLR, PLR, and HALP scores before the KEYNOTE-826 regimen. The AUC values for these scores were 0.644, 0.662, 0.852, 0.667, and 0.700, respectively. The lower NLR (≤5.52) group had a significantly longer median survival than the higher NLR (>5.52) group (p˂0.001), with median survivals of 14.0 vs. 7.6 months, respectively. In group 3, CPS and TPS were highest at 0.700 for predicting progression-free survival, compared to NLR, PLR, and HALP score. CPS and TPS appear positively correlated with progression-free survival. Conclusion: CPS and TPS showed a modest correlation with progression-free survival and NLR prior to immunotherapy demonstrated the best treatment efficacy for advanced cervical cancer.
