Despite significant progress in conventional diagnostic methods such as imaging studies and biomarkers, inherent limitations hinder their effectiveness. The rapid development of large model techniques has unveiled considerable potential for improving imaging-based diagnosis and prognostic evaluation of HCC. This review highlights recent advances in applying large models to HCC, emphasizing developments in deep neural network architecture and multimodal data integration. It examines how these models enhance early diagnosis accuracy through automated feature extraction and explores their role in integrating clinical variables, radiomics, genomics, and pathology data, offering novel perspectives for prognosis assessment. Despite their promise, challenges such as data quality, model interpretability, and generalization capacity remain. The review concludes by discussing the future potential of large models in HCC diagnosis and prognosis, addressing key challenges and ethical considerations for clinical adoption.</div></div>","PeriodicalId":100278,"journal":{"name":"Clinical Surgical Oncology","volume":"4 2","pages":"Article 100083"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144313363","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Advanced guidance can enhance the precision and efficiency of lower abdominopelvic surgical procedures. This can be achieved with image-guided surgical navigation systems, which use preoperative data to display real-time updates of intraoperative data. The current literature review explores the current state and prospective approaches for developing clinical navigation systems tailored for the lower abdominopelvic region. We aim to identify current knowledge gaps and technological challenges in navigation and explore potential solutions proposed in the literature. A comprehensive literature review of the current state of the art of navigation systems was performed. Relevant clinical and technical information from the publications was extracted and added value of navigation systems was analysed. According to the reviewed literature, existing commercial navigation systems focus mainly on rigid structure navigation. Despite being certified for spine, hip, knee and neurosurgery, commercial systems were used in 16 out of 29 studies for non-rigid pelvic surgery, which was outside their intended use. Comparative studies showed that navigation was of added value for surgical efficiency and clinical outcomes. Navigation in lower abdominopelvic surgeries contributed to more precise resection margins and reduction of local recurrences, resulting in more precise and safe surgeries. Various promising navigation systems show high performance in lower abdominopelvic surgery. However, their implementation is mainly examined in feasibility studies. Consequently, the use of navigation systems in clinical standard routine still remains limited.</div></div>","PeriodicalId":100278,"journal":{"name":"Clinical Surgical Oncology","volume":"4 2","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144322200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These digital pathways not only improve accessibility and patient comprehension but also streamline documentation, reducing errors and administrative burdens. AI technologies, including ambient digital scribes and large language models (LLMs), could further augment this process by generating personalized risk assessments, simplifying complex medical information, and facilitating multilingual communication. However, success will also depend on addressing ethical concerns, ensuring equitable access, and preserving the irreplaceable human connection between patients and clinicians.
