Design, development, and evaluation of an advanced cancer surveillance system.
Article in BMC cancer, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundCancer remains a leading global cause of mortality, demanding robust surveillance systems to inform public health strategies. Current cancer surveillance systems, particularly in low-resource settings, often lack on-demand analytics, spatial visualization, and predictive modeling, limiting their utility in addressing disparities and guiding targeted interventions. This study aimed to design, develop, and evaluate a GIS-integrated cancer surveillance systems tailored to the epidemiological and geographical context of Iran.
methodsEmploying a three-phase approach, the study began with a systematic review of cancer surveillance indicators, followed by the design and development of the system using a modular architecture supported by Django and Vue.js frameworks. The system integrates multi-level data standardization, GIS-based spatial analysis, and predictive analytics for on-demand insights. Usability evaluation was conducted using Nielsen's Heuristic Assessment, incorporating feedback from medical informatics specialists, pathologists, and health managers.
resultsThe Cancer Surveillance System incorporated critical data elements validated with CVR (> 0.51) and Cronbach's alpha (0.849). Phase two developed a GIS-integrated, scalable system handling 20 million records, enabling on-demand monitoring, spatial analysis, and risk factor evaluation. Predictive modeling tools forecast cancer trends over 5-, 10-, and 20-year horizons, adhering to WHO standards. Usability evaluation resolved 85% of identified issues, enhancing functionality, user satisfaction, and scalability for precision cancer surveillance.
conclusionThis study presents a scalable and adaptable CSS framework that bridges traditional surveillance limitations and modern analytical demands. Its integration of advanced technologies provides a model for global adaptation, supporting equitable resource distribution and evidence-based cancer control strategies.
