Cobalt-60 sources last about five years and give equivalent doses, so funding cobalt units for every regional centre closes a well-understood cure gap.","summary":"Brachytherapy is essential for curative cervical cancer treatment, yet LMIC radiotherapy centres frequently have none, or have units whose iridium-192 sources cannot be replaced every three months for cost and logistics reasons. Cobalt-60 HDR sources last about five years and are dosimetrically equivalent for cervix. A programme to fund cobalt HDR units, standardise applicators and image-guided planning, and train teams would close a specific and well-understood cure gap.","asOf":"2026-09-08","links":[{"label":"Bottleneck evidence (Most of the world has almost no cancer care): WHO fact sheet, Cancer","url":"https://www.who.int/news-room/fact-sheets/detail/cancer"}],"tags":[],"related":[],"cancers":["cervical"],"sections":["radiation"],"technologies":["brachytherapy"],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-global-access","b-surgery-radiation-innovation"],"keyPapers":[],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"Regional centres receiving a cobalt HDR unit and training will increase the proportion of locally advanced cervical cancer patients completing brachytherapy within the recommended overall treatment time from under 40% to above 80%.","rationale":"The technology is proven and the indication is common; the constraint is a solvable procurement and training problem with a defined cost.","test":"Before-and-after audit of brachytherapy completion, overall treatment time, and three-year local control in ten centres receiving units.","maturity":"early-clinical","actor":"engineering","cost":"medium","horizonYears":3},"route":"/ideas/idea-acc-frugal-hdr-brachytherapy/","neighbours":{"cancer":[{"id":"cervical","kind":"cancer","name":"Cervical cancer","route":"/cancers/cervical/"}],"section":[{"id":"radiation","kind":"section","name":"Radiation Therapy","route":"/fronts/radiation/"}],"technology":[{"id":"brachytherapy","kind":"technology","name":"Brachytherapy","route":"/technologies/brachytherapy/"}],"bottleneck":[{"id":"b-global-access","kind":"bottleneck","name":"Most of the world has almost no cancer care","route":"/bottlenecks/b-global-access/"},{"id":"b-surgery-radiation-innovation","kind":"bottleneck","name":"Surgery and radiotherapy cure most, get least","route":"/bottlenecks/b-surgery-radiation-innovation/"}],"roadmap":[{"id":"global-access-roadmap","kind":"roadmap","name":"Global access and affordability roadmap: essential medicines and generics → biosimilars and frugal trials → reliance, pooling and homegrown innovation","route":"/roadmaps/global-access-roadmap/"},{"id":"radiation-roadmap","kind":"roadmap","name":"Radiotherapy roadmap: X-rays → shaped beams → fewer fractions, particles and FLASH","route":"/roadmaps/radiation-roadmap/"}]}}
