Objetivos. Determinar la relación costo-efectividad de la vacunación contra el (virus del papiloma humano) VPH y el tamiz de lesiones cervicales, frente a un programa de tamiz solo. Materiales y métodos. Se realizó una evaluación costo-efectividad y se empleó un modelo de Markov, con un horizonte temporal de 70 años y tres alternativas de prevención para el (cáncer del cuello uterino) CCU (tamiz solo, tamiz + vacuna bivalente, y tamiz + vacuna cuadrivalente), en una cohorte hipotética de niñas de diez años, desde la perspectiva del Ministerio de Salud. Resultados. La vacunación contra el VPH y tamiz es más costo-efectiva que el tamiz solo a partir de una voluntad de pago de S/ 2000 (USD 1 290,32). En el análisis determinístico, la vacuna bivalente es marginalmente más costo-efectiva que la vacuna cuadrivalente (S/ 48 [USD 30,97] frente a S/ 166 [USD 107,10] por AVAC, respectivamente). Sin embargo, en el análisis probabilístico ambas intervenciones generan nubes de puntos superpuestos, con una tendencia de la vacuna cuadrivalente a ser más costo-efectiva. Es decir, ambas son costo-efectivas y, por ende, intercambiables. El modelo fue especialmente sensible a variaciones de la cobertura y en la prevalencia de infección persistente por genotipos oncológicos no incluidos en la vacuna. Conclusiones. A partir de una disponibilidad de pago de S/ 2000 [USD 1 290,32] el tamiz y la vacunación son más costo-efectivos que el tamiz solo. La diferencia de costo-efectividad entre ambas vacunas carece de robustez probabilística y ambas vacunas pueden considerarse intercambiables desde la perspectiva costo-efectividad. / Objectives. To determine the cost-effectiveness of human papillomavirus (HPV) vaccination and cervical lesion screening versus screening alone for the prevention of uterine cervical cancer (UCC). Materials and methods. This cost-effectiveness evaluation from the perspective of the Ministry of Health employed a Markov model with a 70-year time horizon and three alternatives for UCC prevention (screening alone, screening + bivalent vaccine, and screening + quadrivalent vaccine) in a hypothetical cohort of 10-year-old girls. Results. Our model, which was particularly sensitive to variations in coverage and in the prevalence of persistent infection by oncologic genotypes not included in the vaccine, revealed that HPV vaccination and screening is more cost-effective than screening alone, assuming a payment availability from S/ 2 000 (US dollars (USD) 1 290.32) per subject. In the deterministic analysis, the bivalent vaccine was marginally more cost-effective than the quadrivalent vaccine (S/ 48 [USD 30.97] vs. S/ 166 [USD 107.10] per quality-adjusted life-year, respectively). However, in the probabilistic analysis, both interventions generated clouds of overlapping points and were thus cost-effective and interchangeable, although the quadrivalent vaccine tended to be more cost-effective. Conclusions. Assuming a payment availability from S/ 2000 [USD 1,290.32], screening and vaccination were more cost-effective than screening alone. The difference in cost-effectiveness between the two vaccines lacked probabilistic robustness, and therefore the vaccines can be considered interchangeable from a cost-effectiveness perspective.

O câncer do colo do útero foi incorporado à agenda médica brasileira na década de 1940, a partir do desenvolvimento de ferramentas de diagnóstico precoce e da organização de instituições. Nosso objetivo neste trabalho é analisar o processo de incorporação da doença na medicina brasileira, impulsionado pela introdução e difusão das tecnologias de diagnóstico, no escopo de institucionalização da cancerologia como sub campo da nossa medicina. O Instituto de Ginecologia (IG), no Rio de Janeiro, sob chefia do médico Arnaldo de Moraes, foi o centro de difusão e ensino da colposcopia e da citologia no Brasil. Nossa hipótese de pesquisa é que a colposcopia foi a impulsionadora da formação e organização das instituições de controle do câncer do colodo útero no Brasil em meados do século XX, sendo utilizada de forma conjunta com a citologia até os anos 1960. A organização de ações sobre a doença e as discussões entre os especialistas conduziram à formação de uma rede de prevenção, construída a partir de publicações especializadas, associações profissionais, iniciativas para formação de pessoal e intercâmbio científico. Fizeram parte desta rede o Instituto de Ginecologia, o Hospital de Ginecologia da Faculdade de Medicina de Minas Gerais e o Hospital Aristides Maltez na Bahia. Ambos, com suas peculiaridades, se constituíram como espaços de controle da doença em suas regiões e de institucionalização de um modelo específico de ação que se afirmou no país até a década de 1970. / This study is about the medical actions for cervical cancer prevention in Brasil, from 1936 to 1970. Cervical cancer was incorporated into the medical Brazilian agenda in the 1940s, with the development of early detection tools and the institutions organization. Our objective in this paper is to analyze the disease incorporation on the Brazilian medicine, through the introduction and diffusion of diagnosis technologies, in the scope of cancerology institutionalization as a medicine sub field. The Instituto de Ginecologia (IG), in Rio de Janeiro, under leadership of physician Arnaldo de Moraes, was the learning and dissemination center of colposcopy and cytology in Brazil. Our research hypothesis is that colposcopy was the promoter of the formation and organization of the institutions to cervical cancer control in Brazil in the mid-twentieth century, being used, at the same time, with cytology until the 1960s. The organization of actions about the disease and the discussions among experts led to the formation of a prevention network that was constructed by specialized publications, professional associations, initiatives for personnel training and scientific exchange. The Instituto de Ginecologia, the Hospital de Ginecologia of Minas Gerais and the Hospital Aristides Maltez in Bahia were part of this network. All of them, with their peculiarities, had been constituted as spaces to disease control in their regions and institutionalization of a particular model of action, that was affirmed in the country until the 1970s.
