VIA detection of cervical cancer quality and cheap
Study conducted by scientists show that one for cervical cancer cheap, simple, "low-tech" in the eye screening method will save the world every year thousands of women with cervical cancer. The study, published in the recent "Lancet" magazine.
Cervical cancer in women in developing countries the most common cancer in the world, approximately 85% of cervical cancer patients (nearly 50 million patients) distributed in developing countries, and of which 1 / 4 of the cases thus Death. IARC director PeterBoyle Dr., cervical cancer has become a major global public health burden.
Now used to reduce the incidence of cervical cancer is the preferred method: in more countries as possible to the beginning of life did not allow the vaccination of young women to prevent HPV. For the female sex has occurred, early screening is an effective method, but how to start?
Decades, cervical smear (PapSmeartest) has been used to check for cervical cancer and precancerous lesions become a safe, reliable and effective screening method. However, this method is carried out must be guaranteed by certain laboratory conditions, but it is currently impossible to introduce this approach to all areas, especially in poor areas the most popular of cervical cancer.
In this study, the researchers of a simple and inexpensive screening methods were tested. The use of 4% acetic acid soaked gauze dressing to the subjects with cervical, waiting about 1 minute, then use a bright halogen light, observed by the naked eye. A precancerous lesion of the region under the effect of acetic acid will turn white. This inspection method is called VIA, or with 4% acetic acid after the naked eye coloring.
The study was conducted in resource-poor areas of cervical lesions based on visual observation of one of the most large-scale screening of randomized controlled trials. Of rural areas in India, in 2000 and 2007 more than 30,000 women were screened, and almost the number of women who do not have VIA screening as a control.
In place with a VIA screening 31,000 women, 1,900 were diagnosed as precancerous lesions, 72% were treated. The results show that, VIA screening method can reduce the incidence and mortality of cervical cancer (as long as the lesions found in women receiving effective treatment).
Accepted VIA examination of women and does not accept this kind of examination of women compared to the likelihood of diagnosis of cervical cancer reduced by 25% and will likely die from the disease decreased by 35%.
The study concludes in the conclusion: If the examiner can get good training, and to ensure the continued stability of quality inspection, then the VIA screening in developing countries can be an effective way to prevent cervical cancer.
VIA than other inspection methods, the advantages of a real-time results can be immediately diagnosed, and many medical staff can operate, including nurses. The key to successful screening is that the training of medical personnel and to ensure the quality check.
