The Contouring Lab of the National Institute of Cancer Research and Hospital (NICRH) is a specialized facility within the Department of Radiation Oncology designed to enhance precision and collaboration in cancer treatment planning. Equipped with advanced imaging and radiotherapy planning software, the lab allows oncologists and medical physicists to delineate tumor volumes and organs at risk with high accuracy—an essential step in modern radiation therapy. Beyond its technical capabilities, the Contouring Lab serves as a hub for cross-border consultation and inter-country tumour boards, enabling multidisciplinary discussions among oncology experts from different nations. This collaborative environment fosters shared decision-making, knowledge exchange, and the adoption of best practices in cancer management. By integrating digital tools and telemedicine technologies, the NICRH Contouring Lab plays a pivotal role in strengthening regional cooperation in oncology and improving patient outcomes through evidence-based, globally informed treatment planning.
