Integrative Radiogenomics Using MRI Radiomics and Microarray Gene Expression Analysis to Predict Pathological Complete Response in Patients with Breast Cancer Undergoing Neoadjuvant Chemotherapy.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectivesGiven the variable pathological complete response (pCR) rate of neoadjuvant chemotherapy (NAC) in patients with breast cancer, identifying predictive markers is crucial. This study evaluated the predictive accuracy of three machine learning-based models: (1) radiomics using MRI features; (2) genomics based on DNA microarray data; and (3) radiogenomics integrating both MRI and microarray data to predict pCR after NAC across all breast cancer subtypes. This study aimed to determine which model provides the most precise non-invasive prediction by utilizing a consistent dataset and analytical pipeline.
methodsIn this retrospective study, 112 patients with breast cancer who underwent DNA microarray analysis and dynamic contrast-enhanced MRI before receiving NAC at a single institution between July 2006 and November 2016 were classified into pCR (N = 21) and non-pCR (N = 91) groups. The prediction accuracy of pCR after NAC was evaluated for three models using repeated stratified nested cross-validation (CV). Model performance was assessed by the area under the receiver operating characteristic curve (ROC-AUC), and statistical significance was tested using DeLong's test.
resultsAmong the 112 patients, the radiogenomics model yielded an AUC of 0.607 (95% confidence interval (CI): 0.438-0.758), outperforming both the radiomics (AUC 0.563, 95% CI: 0.410-0.718) and the genomics (AUC 0.559, 95% CI: 0.379-0.722) models. However, this improvement was not statistically significant (p>0.05).
conclusionMachine learning-based radiogenomics, which combines MRI features and DNA microarray data, improved the accuracy of pCR prediction after NAC, although the improvement was not statistically significant. These findings suggest the potential utility of radiogenomics as a non-invasive tool to support treatment decision-making in patients undergoing NAC.
