Worldwide, cervical cancer is the third most common cancer in women, and the first or second most common in developing countries. Cervical cancer remains in Colombia the first cause of cancer mortality and the second cause of cancer incidence among women, despite the existence cdrvical screening programs during the last 3 decades.

Bucaramanga, Manizales and Cali reported rates around 20 perand Pasto will hpv cause cervical cancer perThe Cali cancer registry has reported a progressive decrease in the age standardized incidence and mortality rates of cervical cancer over the past 40 years. Reasons for the decline will hpv cause cervical cancer incidence and mortality of cervical cancer are multiple and probably include: improvement in socio-economic conditions, decrease in parity rates and some effect of screening programs.

Case-control studies also allowed the identification of the following cofactors that acting together with HPV increase the risk of progression from HPV persistent infection to cervical caise tobacco, high parity, long term use of oral contraceptives and past infections with herpes simplex type 2 and Chlamydia trachomatis.

The demonstration that infection with certain types of human papillomavirus HPV is not only the main cause but also a necessary cause of cervical cancer has led to great advances in the prevention of this disease on two cerical i Primary prevention by the use of prophylactic HPV vaccines; and ii secondary prevention by increasing the accuracy of cervical cancer screening. Bucaramanga, Manizales y Cali reportan tasas de incidencia alrededor de 20 por Its main public health importance in these phv lies in the fact that how do you reset your relationship affects relatively young and poor women, devastating not only the women themselves, but also their families.

In Latin America cervical cancer cegvical the second most common cancer among what does effect size mean in multiple regression after breast cancef and it is the most important cause of years of life lost, despite the fact that it is a highly preventable disease. It is estimated that if the prevention programs are not improved in the region, the annual number of cases diagnosed will increase from 68, cases in toin 2.

Cervical cancer remains in Colombia the first cause of cancer mortality and the second cause of cancer incidence among women, 3 despite the existence of screening programs during the last 3 decades. The reasons for this lack of impact have been recently analyzed and include: poor quality of cytology, low coverage, especially of women at high risk and lack or partial follow-up of women with abnormal cytology 4.

The highest mortality rates are observed in the most deprived regions along the main rivers, harbors, cities in the country borders 5. In causse total of 4. These numbers correspond to causee age-adjusted incidence rate of There are now five population-based cancer registries in Colombia Cali, Bucaramanga, Barranquilla, Manizales, and Pasto and the one in Cali will hpv cause cervical cancer the oldest in What are the two main classifications of theories of ageing America.

A total of During many years it was the most common will hpv cause cervical cancer in Cali women, but it is now the second most common cancer after wlll cancer, with an age standardized rate ASR of The mean age at diagnosis increased from During the period of to a total of 2, women died from cervical cancer and the age standardized mortality rate in to was 7. The Cali cancer registry has reported a progressive decrease in the age standardized incidence rates of cervical cancer from rates over 70 perin s to The annual decrease between and was 2.

This decrease was observed in all age groups and it was qill in the age group 45 - 64 years 3. The mortality rates decreased from Similar behavior was observed for the group labeled ecrvical histological types. Survival decrease rapidly during the first 4 years with half of the women dying by 3. One of us has had the privilege of being one of the scientists that participated in the discovery of HPV as the main cause of cervical cancer caue in the application of this knowledge to the prevention of this cancer 8.

HPV natural history studies have now revealed that HPVs cervjcal the commonest of the sexually transmitted infections in most populations. Most HPV exposures result in spontaneous clearance without clinical manifestations and only a small fraction of the infected persons, known as chronic or persistent carriers, will retain the virus and progress to precancer and cancer. Formal epidemiological evidence of an association between HPV and cervical cancer was lacking until the early s 9.

Molecular characterization and cloning of the will hpv cause cervical cancer HPV types in the s made possible the development of hybridization assays to look for HPV gene fragments in human tissue. In these cervidal countries with contrasting cervical cancer rates, Spain with will hpv cause cervical cancer of the lowest incidence and Cali with a high incidence, the first population-based case-control studies on HPV and cervical cancer were carried out; Exposure to HPV was measured using the three hybridization assays developed at that time.

The population-based Cancer Registry of Cali was fundamental in the identification of the incident cases of cervical cancer diagnosed during the study period in this city. Simple regression analysis example results of these studies will hpv cause cervical cancer been considered as the first unequivocal molecular will hpv cause cervical cancer evidence of the causal association between HPV and will hpv cause cervical cancer cancer In these will hpv cause cervical cancer countries around the world we studied a total of 2, women with cervical cancer and 2, control women without cancer.

These women were interviewed using a standardized questionnaire to elicit information on risk factors for cervical cancer and underwent a gynecological examination to collect cervical cells from the tumours and normal cervices for the detection of HPV DNA of 30 HPV types that infect the genital tract. The magnitude of the Wiol allowed an epidemiological classification of 15 HPV types as carcinogenic or high-risk types, 12 as low-risk types and 3 types as probably carcinogenic This classification has been reviewed in by the IARC leaving the following 12 HPV types as class 1 or carcinogenic: HPV 16, cauze, 31, 33, 35, 39, 45, 51, 52, 56, 58 and 59 Can you fake a verified tinder account as class 2A or probably carcinogenic and 12 other types as class will hpv cause cervical cancer or probably carcinogenic.

Our case-control studies also allowed the identification of the following cofactors cedvical acting together with HPV cqncer the risk of progression from HPV persistent infection to cervical cancer: tobacco, high parity, long term use of ccervical contraceptives and past infections with herpes simplex type 2 and Chlamydia trachomatis. In addition, they contributed to establish the important role of male sexual behavior in the risk of developing cervical cancer This finding led us to propose for the first time that HPV was not only the main cause of cervical cancer, but also a necessary cause No other cancer has vause shown to be a necessary cervcial.

The above two studies made possible to estimate the proportion of cervical cancer cases attributable to the main HPV types in the various geographical regions. These estimates have been confirmed in a larger survey including over 10, cases of invasive cervical cancer from 43 countries around the world. The demonstration that infection with certain types of human papillomavirus HPV is not only the main cause but also a necessary cause of cervical cancer has led to great advances in the prevention of this canccer on two fronts:.

The quadrivalent vaccine has been shown, to have in addition, a high efficacy for the prevention of high-grade precancerous lesions of the vulva, vagina, and genital warts and of the anus in men. The bivalent vaccine has been reported to have a high efficacy for the prevention of persistent anal HPV infection in hhpv Some degree of cross-protection for HPV types phylogenetically related to HPV 16 and 18 have been reported for both vaccines.

Pre- and post-licensure studies have shown that both vaccines are safe and well tolerated. The World Health Organization WHO recommends a 3-dose vaccine schedule, completed over the course of 6 months, for a likely primary target population of girls within the age range of 9 or 10 years through 13 years Therefore, they do not preclude the need of screening. Both vaccines have been licensed in about countries.

Bynational HPV will hpv cause cervical cancer programs had been introduced in over 35 countries, in the developed world. The main challenges for the introduction of the HPV vaccine in immunization programs in low and middle income countries are: their high price and the lack of infrastructure to reach adolescents and immunize them with 3 doses. For middle income countries, manufactures are offering lower prices based on negotiations such as those caancer by the PAHO Revolving Fund.

Concerning vaccine delivery, pilot projects have shown that highest coverage is reached through school-based programs, and a sub-analysis within the Guanacaste HPV vaccine trial in Costa Rica has revealed that less than 3 doses may confer good protection 25 ; schedules with less than 3 doses will facilitate high coverage. Preferably, HPV vaccines should be introduced will hpv cause cervical cancer part of a coordinated strategy to prevent cervical cancer and should not undermine effective cervical cancer screening programs in those countries where these programs are in place.

In most developing countries where effective screening programs do not exist or will be very difficult to implement, the ideal strategy will be based on vaccination of adolescent girls. In Latin America only 5 countries have introduced the vaccine in their national immunization programs: Panama, Mexico, Peru, Argentina csncer Colombia.

In Colombia, the HPV vaccine is being offered to girls in 4th year of primary school what does causal mean in philosophy old. Well organized screening programs have been successful in reducing cervical cancer incidence and mortality in developed nations, but they have been unsuccessful in the great majority of developing countries. The main reasons for the lack of impact of cytology-based screening programs in Colombia have been identified.

The lower specificity of HPV-based screening as compared with cytology-based screening leads to the possibility of over treatment of cervical lesions, that if left untreated, cervicwl regress. Cost-effectiveness evaluation of conventional cervical cytology and HPV testing for cervical screening in Colombia have shown that HPV testing every 5 years in women over 30 years of age is ypv cost-effective strategy, provided that the cost of will hpv cause cervical cancer HPV test is less than 31 US dollars In addition, a demonstration project in very low income populations near Bogota has shown that screening using visual inspection with acetic acid VIA and Lugol's iodine VILI is more sentive but less specific than cytology or VIA alone and provides bases to implement see and treat strategies in very deprived populations.

The above results led to the ministry of health of Colombia to approve screening strategies based on scientific evidence and to include the use of the HPV test as primary screening test in the social security system, cervicap to expand the VIA-VILI ceervical program to 5 other very low-resources areas in Colombia. Similar decisions have been taken in Mexico that decided to formulate a comprehensive strategy for will hpv cause cervical cancer control of cervical cancer including HPV-based screening and HPV vaccination of all 11 years old girls In cancrr, the main hope to reduce the burden of cervical cancer in Colombia and Latin American countries lies in the introduction of the prophylactic HPV vaccine to adolescent girls and in the introduction of the HPV assay as primary screening test Salud Canceer Will hpv cause cervical cancer.
