...large, longitudinal study, conducted in nearly 500 villages in the rural Osmanabad district of central India, analyzed the effectiveness of three methods of screening, including the standard pap smear and the newer test for human papillomavirus, or HPV, whose sexually transmitted high-risk strains are known to cause cervical cancer.

...Sankaranarayanan's study involved more than 130,000 women, ages 30 to 59, who were randomly divided into three test groups and a control group. Women in the test groups were screened using one of three tests: a pap smear, an HPV test or a visual inspection of the cervix after application of acetic acid (VIA), a component of vinegar that causes precancerous lesions to turn white. Among the study participants, only eight had ever undergone cervical cancer screening before. Women in the control group were informed about the causes and dangers of cervical cancer and instructed where they could...
...appears to be a better test for screening," Sankaranarayanan says, reaffirming previous studies that have established a strong correlation between positive tests for HPV and development of cancerous lesions...
...From a practical standpoint, limiting HPV testing to women over 30 can also reduce unnecessary costs in treating patients in whom the infection would have resolved itself, a particularly important factor to consider when attempting to get cervical cancer prevention programs off the ground in the developing world and among lower-income women, Sankaranarayanan says. Indeed, the current standard in HPV tests, the Hybrid Capture II, which was used for this study, is already too costly for wide-scale application, running as much as $30 per test. Realistically, in order to be used on a grand scale, tests would have...
...that respect, there may be hope on the horizon. A Chinese study, funded in part by the Bill & Melinda Gates Foundation (as was the current study) and published in 2008, reported that a new HPV test, called careHPV, is easier to use, produces results faster and is just as effective as the Hybrid Capture II. Researchers say that when careHPV becomes available - Sankaranarayanan anticipates it will be on the market within two years - it will cost a fraction of the price of the Hybrid Capture...
