New Test for Cervical Cancer Poised to Be a Boon in Developing World
Screening for cervical cancer is routinely done in rich countries and has helped cut mortality from this disease in advanced economies by between 50 and 80 percent.
But the technique requires access to sophisticated labs, which makes it unsuitable for countries that lack financial resources and medical infrastructure and may not even have electricity in remote areas.
Researchers said a prototype of a straightforward, affordable test had been tested in trials among nearly 2,400 women in rural China and proved to be highly accurate.
Pap smears identified as pre-cancerous by lab screening were spotted by the device 90 percent of the time. It was also 84.2 percent accurate in identifying samples that were not precancerous.
The gadget, called careHPV, amplifies telltale strands of DNA found in the human papillomavirus (HPV) which causes cervical cancer. It is a spinoff of a lab technology called Hybrid Capture 2.
Able to detect 14 high-risk types of HPV, the mini-lab needs an area of clean benchtop workspace that is about the size of a tabloid newspaper.
It does not require mains electricity or running water and can be used by non-technical support staff.
The test results come in around two and a half hours, which means a woman can be screened and given help in the same visit if need be.
