Radiomics-based unsupervised clustering and deep learning nomogram for response prediction after neoadjuvant chemotherapy in locally advanced laryngeal cancer.
Article in BMC medical imaging, 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
objectivesTo develop a nomogram model for individualized prediction of neoadjuvant chemotherapy (NAC) response in locally advanced laryngeal cancer (LALC).
methodsA total of 175 patients who underwent CT examinations before NAC from two hospitals were retrospectively enrolled and divided into training (n = 112) and test (n = 63) sets. Significant radiomics and clinical features were selected sequentially, and consensus clustering was used to identify tumor subtypes. A nomogram model for predicting remission status was constructed by fusing clinical signature, radiomics signature, cluster result and deep learning signature. The predictive performance of junior and senior doctors for NAC response was evaluated with and without model assistance.
resultsTwo radiomics subtypes (Subtype A and B) were identified. Compared with Subtype A, Subtype B had higher frequencies of heterogeneous tumor density (all P < 0.001) and marked venous-phase enhancement (all P < 0.05) in both sets. The nomogram-derived remission score showed good predictive performance for NAC response, with AUCs of 0.935 (training set) and 0.912 (test set). Survival analysis revealed that patients with high remission scores had better overall survival (OS) and locoregional control than those with low scores (all P < 0.05) in both sets. Model assistance improved the predictive performance of junior (AUC: 0.799 vs. 0.915) and senior doctors (AUC: 0.849 vs. 0.919, all P < 0.05).
conclusionThe nomogram model based on two-center databases achieved good performance in predicting NAC response and survival in LALC patients, which may contribute to the personalized treatment of LALC.
