According to the World Health Organization (WHO), the second cause of morbidity and mortality in Brazil is cancer. Malignant neoplasm of the head and neck is considered one of the main tumors in Brazil and in the world, with high mortality rates. This is due to the diagnosis, which is made late, often when the disease has advanced clinical stages, reaching metastasis. This work is a descriptive study of secondary data carried out through a survey by the Department of Informatics of the Brazilian Unified Health System. After obtaining the data, they were tabulated. A literature review was also carried out to support the research, using the Google Academic, Scielo and Pubmed platforms. The analysis was performed using mortality data from malignant neoplasms of the lip, oral cavity and pharynx in Pernambuco from 1996 to 2019 and, according to the survey, 6,121 deaths were registered. The data showed a higher mortality rate in males; patients between 55 and 64 years old; in addition to brown people. The highest number of deaths in individuals with less education was also observed. Although studies on the prevention and cure of cancer are currently intermittent, the data analyzed show that the rates of appearance of new cases have grown in recent years and tend to increase in the next due to daily life habits. Thus, it is important to invest in research aimed at inhibiting the appearance of new neoplasms.

INTRODUCTION: The hepatitis B virus (HBV) is transmitted through corporal fluids as infected people’s blood and semen. Thus, sexual intercourse, blood transfusion, accidents with sharp materials are some of the main mechanisms of transmission of this virus. The HBV has tropism for hepatic cells and the infection by the virus can evolve on variable clinical conditions. The vaccine against hepatitis B has been available on the SUS (Brazilian Unified Health System) since 1998 and is an important collective prevention strategy. The present research aims to perform a sociodemographic evaluation of the hepatitis B diagnoses between the years 2007 and 2018, and to correlate it with the advances of the vaccination coverage in Brazil against hepatitis B. MATERIALS AND METHODS: This is an ecological study, retrospective and descriptive study that it has as methodology the use of secondary data from Sistema de Informação de Agravos de Notificação (SINAM). The sample was composed of all acute hepatitis B’s diagnoses in Brazil during the period from 2007 to 2018, totalizing 21432 records. In the research, the following variables were used: sex, age group, skin color/race, marital status, and schooling. RESULT AND DISCUSSION: This study has demonstrated that the male gender, as well as the brown population represents the largest number of cases. From the evaluation of the variables age and schooling, it was concluded that the population at the age group that, in general, is sexually active (from 20 to 39 years) is the most affected, and the population that presents low schooling characterizes the majority of individuals infected with HBV. FINAL CONSIDERATIONS: It is necessary to expand vaccination coverage by identifying the weak points of vaccination activity, besides the supply of the vaccine, location and adequate schedule to help the health system’s user accession. It is essential that the public policy of information and the campaigns are also directed to health professionals.

INTRODUÇÃO: As ligas acadêmicas são um fenômeno ascendente na educação superior brasileira. Essas entidades são dirigidas, protagonizadas e direcionadas por e para o corpo discente, constituindo um espaço propício à integração da teoria com a prática e aproximação da academia com a comunidade. Assim, os ligantes podem desenvolver atividades que unificam os três pilares universitários -ensino, pesquisa e extensão -consolidando o papel social da universidade. OBJETIVO: Relatar a experiência na Liga Acadêmica de Oncologia da Universidade Federal do Vale do São Francisco (ONCOLIGA-UNIVASF) a partir do projeto de Extensão "Medidas de prevenção, diagnóstico e abordagem precoce do câncer de pele em trabalhadores da agricultura em área irrigada do sertão do São Francisco". METODOLOGIA: Estudo qualitativo, baseado em relatos de experiências de estudantes que participaram da ONCOLIGA, nos anos de 2020 e 2021, associado a revisão de literatura integrativa nas bases de dados da Biblioteca Virtual em Saúde (BVS) e Google Scholar. RESULTADOS: Os discentes foram capacitados a utilizar aplicativo para detecção de lesões, praticaram técnicas de biópsia e se aprofundaram na semiologia dermatológica e no processamento anatomopatológico para realização do projeto de Extensão. Habilitados e utilizando ferramentas corretas, os ligantes desenvolveram um projeto de Pesquisa intitulado "Avaliação de fatores de risco para desenvolvimento de câncer de pele em trabalhadores da agricultura em área irrigada do sertão do São Francisco", apoiado pelo Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq). O conhecimento teórico e prático tem sido utilizado em ações de extensão, como a campanha contra o câncer de pele (cerca de 168 pacientes atendidos), e em palestras direcionadas a trabalhadores rurais de Petrolina/PE (cerca de 610 ouvintes), com orientação sobre a importância da prevenção e do diagnóstico precoce do câncer de pele. CONCLUSÕES: A ONCOLIGA tem cumprido seu papel fundamental, colaborando ativamente para melhoria da comunidade externa em que a UNIVASF está inserida, através da iniciativa em realizar projetos que visam à prevenção e o combate de doenças em grupos frequentemente desassistidos do acesso à saúde. Ademais, colabora com a formação profissional dos estudantes, auxiliando-os para uma prática médica integrativa, equitativa e humana.
