TL;DR
An international trial demonstrates that AI technology can produce high-quality radiotherapy plans for cervical cancer in under an hour. This could help address global treatment disparities, especially in low-resource settings, supporting efforts to eliminate cervical cancer.
An AI technology has been shown to produce high-quality radiotherapy plans for cervical cancer in a large international trial, potentially transforming treatment access worldwide. The results, presented at the ESTRO 2026 congress, confirm the AI’s effectiveness in resource-limited settings, supporting global efforts to eliminate cervical cancer.
The ARCHERY trial involved over 1,000 patients across hospitals in India, South Africa, Jordan, and Malaysia. It found that the AI software could plan radiotherapy to a high standard in more than 95% of cervical cancer cases and 85% of prostate cancer cases, with results for head and neck cancers pending.
Planning radiotherapy traditionally requires several hours or days of work from specialized oncologists and physicists. The AI tool automates this process, reducing planning time from days to just over an hour, which can help reduce waiting times and increase treatment capacity, especially in low-income countries where skilled staff are scarce.
Why It Matters
This development matters because cervical cancer causes approximately 350,000 deaths annually, mostly in low- and middle-income countries where access to radiotherapy is limited. By enabling faster, high-quality treatment planning, the AI tool could significantly improve survival rates and support global health initiatives aimed at eliminating cervical cancer.
Moreover, the technology’s ability to streamline radiotherapy planning could lead to broader adoption of advanced cancer treatments worldwide, reducing disparities and saving millions of lives.

Background
Currently, only 10% of patients in low-income countries who need radiotherapy receive it, due to workforce shortages and resource limitations. The ARCHERY trial builds on prior research by providing large-scale, multi-country evidence that AI can match the quality of traditional planning methods. This trial is notable for its rigorous design and inclusion of diverse resource settings, addressing a gap in existing research that often focuses on high-income countries.
“These results show that for cervical cancer, this AI technology achieves a very high standard, supporting its routine use in hospitals globally. It can help meet the WHO’s cervical cancer elimination initiative.”

Key Questions
How does the AI improve radiotherapy planning?
The AI automates the identification of tumor targets and optimal radiation beam configurations, reducing planning time from days to just over an hour, while maintaining high quality standards.
Will this AI tool be available in low-income countries?
While the trial shows promising results, widespread adoption depends on regulatory approval, infrastructure, and training. The technology aims to support, not replace, existing healthcare systems.
Does this mean all cervical cancer patients will get faster treatment?
The AI can significantly reduce planning times, potentially increasing treatment capacity, especially where resources are limited. However, actual access depends on healthcare infrastructure and resource availability.
Are there any risks associated with using AI for treatment planning?
Current evidence indicates the AI produces plans of comparable quality to manual planning. Ongoing evaluation and clinical oversight are essential to ensure safety and effectiveness.
