While digital pathology-based survival models leveraging artificial intelligence show promise, they often overlook complementary data sources. Conversely, imaging lacks cellular detail, and genomics/proteomics entail complexity and cost. To integrate multidimensional data for enhanced survival prediction, we propose SurvGRN, a multi-feature fusion framework. SurvGRN synergistically combines clinical variables, transcriptomics, and digital pathology slides using a gated residual network architecture. Pathological features are extracted via multiple instance learning, while clinical and transcriptomic data are processed as static inputs. These features are dynamically fused using a long short-term memory (LSTM) network for comprehensive survival risk assessment. Evaluated on 400 bladder cancer patients, SurvGRN significantly outperformed existing methods: improving the C-index by 12.6% over DeepMISL; 20.6% and 7.1% over graph-based models (DeepGraphConv and Patch-GCN); and 5.4% and 4.0% over attention-based approaches (Surformer and HVTSurv). Ablation studies confirmed the contributions of pathology features (extracted via ResNet-50 pre-trained on bladder tissue), clinical/transcriptomic data, and the LSTM fusion. SurvGRN also enabled significant stratification of patients into distinct risk cohorts. This work demonstrates that holistic integration of multi-source data through tailored fusion architectures substantially improves bladder cancer survival prediction.</p>","PeriodicalId":14401,"journal":{"name":"International journal of surgery","volume":"112 7","pages":"13092-13104"},"PeriodicalIF":9.0,"publicationDate":"2026-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13336688/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148874350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Limitations of this learning model include the availability of trainers and human-factor biases. Increased routine surgical and endoscopic video recording and storage promote video-based learning (VBL) methods. VBL could shorten the learning curve by increasing trainer availability and democratizing training access for procedures such as endoscopic sleeve gastroplasty (ESG), which is carried out by a few expert operators. The aim of this work was to evaluate video annotation as a learning tool for ESG.</p><p><strong>Methods: </strong>Videos of ESG performed at a single center were collected and annotated. An annotation manual developed by an ESG expert was used by three annotators with different levels of endoscopic and ESG expertise. Pairwise Cohen's kappa was used to assess inter-rater reliability (IRR). Completion of the learning curve for each phase and feature of ESG was calculated as the probability of accordance among annotators and estimated by a moving average optimization model with an expectation-maximization algorithm.</p><p><strong>Results: </strong>In total, 40 ESG videos were annotated. IRR pairwise kappa scores ranged between 0.44 (Annotator 1 and 3) and 0.58 (Annotator 2 and 3).

Tailoring training for different trainees could lead to the shortening of learning curves. Some features of ESG are mastered more quickly; however, careful and repeated practice is essential for minimizing errors in more complex features.
