Temporal radiomics for non-invasive preoperative prediction of pathologic complete response to neoadjuvant chemoimmunotherapy in non-small cell lung cancer.
Article in Cancer biology & medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
objectiveThis study aimed to develop and validate a temporal radiomics model based on pre- and post-treatment CT scans for the preoperative prediction of pathologic complete response (pCR) in patients with resectable non-small cell lung cancer (NSCLC) undergoing neoadjuvant chemoimmunotherapy (NCI).
methodsData from 263 patients with resectable NSCLC who underwent NCI followed by curative surgery and had both pre- and post-treatment CT scans were retrospectively collected. Patients from one hospital were randomly divided into training and internal test sets at a 7:3 ratio, while patients from two other hospitals served as the external test set. Radiomics features were extracted from the CT scans at both timepoints and delta features capturing the temporal changes were calculated. Radiomics models based on different features were developed using the least absolute shrinkage and selection operator for feature selection, followed by logistic regression. Model performance was evaluated using the area under the curve (AUC).
resultsThe radiomics model based on delta features yielded AUCs of 0.85, 0.76, and 0.72 in the training, internal test, and external test sets, respectively, which were superior to the radiomics models based on pre-treatment features (0.74, 0.66, and 0.62, respectively) and post-treatment features (0.80, 0.76, and 0.65, respectively). By integrating the optimal features from all three feature sources, the combined model achieved further improvements in performance, with AUCs of 0.89, 0.85, and 0.78, respectively, across the three sets.
conclusionsA CT-based radiomics model incorporating temporal features from pre- and post-treatment scans shows favorable performance for the non-invasive preoperative estimation of pCR to NCI in patients with NSCLC.
