Diagnóstico de cáncer de laringe con transformers y segmentación

Early screening of laryngeal cancer is critical for improving survival rates and patients quality of life. Traditionally, narrow-band imaging (NBI) endoscopy has become a standard diagnostic tool, but its interpretation heavily depends on clinician experience, leading to interobserver variability and limiting its use in resource-constrained settings. In this context, artificial intelligence, especially transformer-based models, is opening a new path to automate and objectify NBI image analysis, distinguishing benign from malignant lesions with accuracy already exceeding 82% in metrics like F1 and accuracy. However, the true added value lies not only in classification, but in the ability to explain why a model reaches a particular decision. This is where combining Vision Transformer with advanced segmentation techniques—such as MedSAM—provides an explainability layer essential for clinical practice. By overlaying heat maps or regions of interest on the original image, the clinician can visualize exactly which tissue areas influenced the diagnosis, building trust and facilitating human validation of the result.

From a technological perspective, implementing such a system requires robust data infrastructure, algorithms trained on massive volumes of annotated images, and an interface that seamlessly integrates the model reasoning into the specialist workflow. At Q2BSTUDIO, as a software development and technology company, we address these challenges by combining our expertise in AI with agile methodologies and deep knowledge of the healthcare sector. It is not just about building a classifier; it is about designing a complete system that includes image ingestion from endoscopic equipment, cloud preprocessing—leveraging services like cloud AWS/Azure—model deployment with sub-second response times, and visualization of explanations in interactive clinical dashboards. Moreover, cybersecurity is a non-negotiable pillar: patient data is protected through end-to-end encryption and role-based access controls, complying with regulations such as GDPR. To this end, we offer specialized cybersecurity that ensures data integrity and confidentiality.

The key to success of a Vision Transformer-based screening system lies in modularity and scalability. Instead of a monolithic solution, we propose a microservices architecture where each component—classification, segmentation, explainability—can be updated independently. This allows improvements to the model without service interruption, as well as horizontal scaling according to examination volume. Explainability, moreover, is not limited to heat maps; it can be enriched with textual annotations describing pathological findings, generated by conversational AI agents acting as virtual assistants for the radiologist. These AI agents can answer questions like 'what feature of the lesion is most relevant for diagnosis?' and provide bibliographic references, all integrated into a dashboard based on BI/Power BI that allows hospital managers to monitor screening effectiveness in real time.

From a business perspective, adopting these tools gives healthcare centers a competitive advantage by reducing costs, minimizing diagnostic errors, and optimizing waiting times. Automating NBI image analysis through process automation frees specialists from repetitive tasks, focusing their effort on the most complex cases. Furthermore, the ability to connect these systems with electronic health records and telemedicine platforms opens the door to population screening initiatives in rural areas or regions with a shortage of otorhinolaryngologists. In this regard, at Q2BSTUDIO we develop custom software that adapts to each hospital specific needs, integrating everything from image capture to structured report generation.

The future of laryngeal cancer screening lies in a symbiosis between clinical judgment and the computational power of transformers. Explainability acts as a bridge, transforming the black box of AI into a transparent and collaborative assistant. For this vision to materialize, it is necessary to have technology partners who understand both the complexity of the medical domain and the demands of high-performance software development. At Q2BSTUDIO we combine decades of experience in cloud computing, artificial intelligence and cybersecurity to deliver solutions that not only classify, but explain and empower. If your institution is interested in implementing an intelligent and explainable screening system, we invite you to contact us to explore how we can adapt these capabilities to your clinical reality.
