Radiomic Analysis and Liquid Biopsy in Preoperative CT of NSCLC: An Explorative Experience.
Article in Thoracic cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
backgroundNonsmall cell lung cancer (NSCLC) remains a significant global health burden, necessitating advancements in diagnostic and prognostic strategies. Liquid biopsy and radiomics offer promising avenues for enhancing preoperative assessment and treatment planning in NSCLC.
methodsThis prospective study enrolled 60 NSCLC patients who underwent both computed tomography (CT)-guided biopsy and liquid biopsy. Radiomic features were extracted from CT images, and circulating tumor DNA (ctDNA) was sequenced to identify genetic mutations. Machine learning algorithms were employed to assess the association between radiomic features and gene mutations.
resultsAmong 57 patients with available data, associations between radiomic features and gene pairs mutation obtained from liquid biopsy exhibited moderate accuracy (approximately 0.60), with texture features demonstrating higher importance. However, when predicting the combined mutation status of gene pairs (e.g., EGFR and ROS1), the classification task involved three classes and yielded substantially lower accuracy (approximately 0.30), likely due to class imbalance and increased complexity. DISCUSSION: Our findings demonstrate a moderate association between radiomic features and single gene mutations detected through liquid biopsy in NSCLC patients, with classification accuracies reaching approximately 0.60. In contrast, classification performance significantly declined (to ~0.30) when gene mutation pairs were used as targets, likely due to increased complexity and class imbalance. Notably, second-order texture features showed the highest importance in the models. These preliminary results suggest that radiomics may capture aspects of tumor biology reflected in liquid biopsy, warranting further validation in larger, well-balanced cohorts.
conclusionThe integration of liquid biopsy and radiomics holds promise for enhancing preoperative assessment and personalized treatment strategies in NSCLC. Further research on larger cohorts is warranted to validate the findings and translate them into clinical practice.
