A new study says that the rapid expansion of HPV vaccination and cervical cancer screening could eliminate cancer as a major health problem in many countries by the end of the century.
HPV (Human Papilloma Virus) is the origin of most cases of cervical cancer. The researchers determined that more than 13 million cases of cervical cancer worldwide could be prevented over the next few decades.
Plus a major public health problem
"Despite the enormity of the problem, our findings suggest that global elimination is at hand with the tools already available, provided that high coverage of HPV vaccination and cervical cancer screening is available." Uterus can be reached, "said Karen Canfell, head of study at the Cancer Council. New South Wales in Sydney, Australia.
The authors of this first global modeling study noted that in rich countries, such as the United States and Canada, cervical cancer should be eliminated as a public health problem. 39, here 25 to 40 years.
The researchers concluded that while high rates of HPV vaccination and uterine cervical cancer screening could be achieved in all countries by 2020, the number of cervical cancer cases was 39 uterus could be reduced by 13.4 million by 2069.
This would mean that the annual average case rate worldwide could fall to less than four cases per 100,000 women by the end of the century, at which point cervical cancer is no longer considered a problem of major public health, added the authors of the study.
If high levels of HPV vaccination and cervical screening can not be achieved worldwide, more than 44 million women could be diagnosed with cervical cancer over the past 50 years. In the next few years, from 600,000 in 2020 to 1.3 million by 2069, due to population growth and aging, the results showed.
Two-thirds of these cases, and about 15 million deaths from cervical cancer, would occur in low- and middle-income countries, according to the study published in Lancet Oncology.
Large disparities between countries
In early 2018, the World Health Organization called for coordinated global action to eliminate cervical cancer, which is highly preventable.
"The WHO's call for action offers a huge opportunity to increase the level of investment in proven interventions against cervical cancer in the world." the poorest countries in the world.If these measures are not adopted, millions of preventable premature deaths will be avoided, "said Canfell in a newspaper. Release.
Cervical cancer is the fourth most common cancer among women, with approximately 570,000 new cases diagnosed worldwide in 2018. Of these, approximately 85% have occurred in less developed countries.
HPV vaccination can prevent 84 to 90% of cervical cancers, and there are proven methods for detecting and treating pre-cervical cancer.
However, the authors of the study noted wide disparities in cervical cancer screening and HPV vaccination rates. In low- and middle-income countries, overall screening rates in 2008 were as low as 19 percent, compared with 63 percent in high-income regions.
The US Centers for Disease Control and Prevention currently recommend routine vaccination of girls and boys against HPV before the age of 11 and 12, because protection is better if it is practiced before the onset of badual activity. .
