Is the second largest cause of mortality due to cancer in women in the developing world.1 Like Latin America. Every year are diagnosed 63.068 women with cervical neoplasia, registering 29.222 deaths by this sickness 2. If current trends continue, the number of deaths in the Americas will grow by 45% in 2030. Mortality rates are 3 times higher in Latin America and the Caribbean than in North America, demonstrating huge inequalities in health. 1Ferlay et al., 2015 SITUACIÓN DE LOS PROGRAMAS PARA LA PREVENCIÓN Y EL CONTROL DEL CÁNCER CERVICOUTERINO OPS 2’00 Maribel Almonte, PhD, Lazcano et al.Nuevos paradigmas y desafíos en la prevención y control del cáncer de cuello uterino en América Latina. Salud pública de méxico / vol. 52, no. 6, noviembre-diciembre de 2010 What happen in Latino América? Most of the developing countries recognized the huge burden of disease and the need for positive actions in reducing the incidence of new cases of cervical cancer and its mortality. All countries have a National Program for prevention and control of cervical cancer. Primary and secondary prevention : -Difficulty in reaching the coverage -Timely diagnosis and tratments -Underreporting SITUACIÓN DE LOS PROGRAMAS PARA LA PREVENCIÓN Y EL CONTROL DEL CÁNCER CERVICOUTERINO OPS 2’00 Vaccination coveraje recent Although it is recommended that each issue be addressed in a fully informed decision-making process, some factors may outweigh and override others, depending on the specific circumstances. In addition, each country must decide what locally-gathered evidence they require in order to make a decision, and for what types of evidence they can rely on country or regional estimates (e.g., disease burden, cost-effectiveness) prepared by other groups, instead of conducting their own studies. As a result of this assessment of the issues, the decision might be to intr oduce the vaccine or not to introduce it at this time. Policy-makers may have to make further decisions about the scope of vaccination, target ages and schedule, and the specific vaccine product, since these have policy and financial implications. Countries that choose not to introduce a vaccine may decide to revisit the issue at a later date as Cervical Cancer in mor Latine evidence of the diseaseAmerica burden or impact and cost-effectiveness of the vaccine becomes available, or as conditions change, such as the supply and price of the vaccine, financial resources, and the ability of the immunization pr ogramme and health system to handle the vaccine.

Angioli et al. /Ten years of HPV vaccines: State of art and controversies Critical Reviews in Oncology/Hematology 102 (2016) 65–72 HPV Vaccination Programs HPV vaccination programs have been implemented in many countries between 2006 and 2009, two different human papillomavirus virus (HPV) vaccines were licensed.1 Both vaccines were shown to prevent up to 90–100% of infection of HPV and precancerous lesions in women not infected with HPV 16–18 at the time of vaccination. In 2014 a nonavalent vaccine was licensed to protect against the five most common oncogenic HPV types that account for the 90% of invasive cervical cancer in the world.2 1Herrero et al., 2015 2. Joura et al., 2014; Tjalma et al., 2013. HPV Role In The Etiology Of Other Neoplasias The persistent high-risk HPV infection is necessary but not sufficient in the pathogenesis of cervical cancer (Walboomers et al., 1999) and it is well known that HPV has a major role in the etiology of squamous cell carcinoma of the anus, vulva, vagina, penis, mouth and oropharynx.1 EDL EDL EDL 1.

HPV associated to other sickness Clinical Therapeutics/Volume 36, Number 1, 2014 Fotografía Elsa Díaz López HPV vaccine results Quadrivalent vaccine showed a 100% efficacy in preventing vulvar and vaginal lesions associated with vaccine HPV types, furthermore in men it was able to reduce 90% penile, perianal and perineal diseases and 100% of penile intraepithelial lesions associated with HPV types.
