A further critical barrier to developing reliable predictive biomarkers is data set shift, which undermines model generalizability. Here, we address these challenges by developing a novel adversarial validation (AV)-integrated machine learning framework, focusing on immunogenic cell death (ICD)-related gene signatures (ICDRSs). We designed three AV-based strategies to mitigate data set shift and validate the efficacies across multiple machine learning algorithms. Using dual-modal data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO), four optimal AV-based classifiers (e.g., GradientBoosting, XGBoost, LGBM, and CatBoost) were screened, which effectively reduced inter-cohort shift, enhancing both accuracy and robustness of downstream analysis. We identified novel risk/protective ICDRSs that strongly predicted patient survival and tumor immunogenicity across cancers. High-risk ICDRSs correlated with immune-exclusive microenvironments marked by impaired antigen presentation and aberrant tumor-associated macrophage development, as revealed by single-cell RNA sequencing. Validation across 13 ICI-treated cohorts revealed the capacity of ICDRSs for anti-PD-1 nonresponse. Mechanistically, risk ICDRSs were linked to CD47-SIRPA-mediated immune evasion and proliferative macrophage subsets with terminal dysfunction.

In dentistry, panoramic radiographs (PRs) are widely used for mandibular canal evaluation, but their reported detection rates for bifid variants (0.038%–1.98%) fall far below those of cone-beam computed tomography (CBCT; 10%–66%), highlighting a need for improved diagnostic tools. Here, we address this gap by developing a deep learning-based tri-comparison expertise decision (TED) system to automate mandibular canal variant classification on PRs. Using retrospective data from 442 mandible sides (279 participants, aged 18–32 years), we validated PRs against CBCT ground truth and decomposed multi-class classification into pairwise comparisons with an “Another” class to enhance discrimination of anatomically similar variants. Here we show that the TED system achieved superior diagnostic accuracy (0.701, 95% CI: 0.674–0.728) and AUROC (0.854, 95% CI: 0.824–0.884) compared to assessments by five experienced dentists (highest accuracy: 0.683; AUROC: 0.810), while also revealing strikingly low inter-rater agreement among experts (Fleiss' kappa = 0.046). These results demonstrate that the TED approach not only outperforms manual evaluations but also provides consistent, cost-effective automation of a task prone to human variability. By bridging the performance gap between PRs and CBCT, this tool offers a practical solution for preoperative risk assessment in dental practice. Broader validation across diverse clinical settings could further solidify its role in improving diagnostic workflows and patient outcomes.</p>","PeriodicalId":74135,"journal":{"name":"MedComm - Future medicine","volume":"4 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mef2.70029","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144861803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
