Objective To compare death rates by COVID-19 between pregnant or postpartum and nonpregnant women during the first and second waves of the Brazilian pandemic. Methods In the present population-based evaluation data from the Sistema de Informação da Vigilância Epidemiológica da Gripe (SIVEP-Gripe, in the Portuguese acronym), we included women with c (ARDS) by COVID-19: 47,768 in 2020 (4,853 obstetric versus 42,915 nonobstetric) and 66,689 in 2021 (5,208 obstetric versus 61,481 nonobstetric) and estimated the frequency of in-hospital death. Results We identified 377 maternal deaths in 2020 (first wave) and 804 in 2021 (second wave). The death rate increased 2.0-fold for the obstetric (7.7 to 15.4%) and 1.6-fold for the nonobstetric groups (13.9 to 22.9%) from 2020 to 2021 (odds ratio [OR]: 0.52; 95% confidence interval [CI]: 0.47–0.58 in 2020 and OR: 0.61; 95%CI: 0.56– 0.66 in 2021; p < 0.05). In women with comorbidities, the death rate increased 1.7-fold (13.3 to 23.3%) and 1.4-fold (22.8 to 31.4%) in the obstetric and nonobstetric groups, respectively (OR: 0.52; 95%CI: 0.44–0.61 in 2020 to OR: 0.66; 95%CI: 0.59–0.73 in 2021; p

Orientador: Luiz Carlos Zeferino Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: INTRODUÇÃO: O exame citológico ainda é o método de rastreamento mais utilizado para a prevenção do câncer do colo do útero. Apesar da sua alta eficiência na prevenção do carcinoma escamoso invasivo, esses benefícios não são tão claros para as lesões escamosas em mulheres jovens e para o adenocarcinoma invasivo. Além disso, esse efeito protetor varia de acordo com o intervalo de realização dos controles. Uma vez que o teste de HPV não é recomendado para mulheres com menos de 30 anos de idade, a avaliação cuidadosa do desempenho do rastreamento neste grupo etário pode auxiliar os médicos a selecionar criteriosamente aquelas que irão ser encaminhadas para prosseguimento diagnóstico. OBJETIVO: Avaliar o impacto do rastreamento do câncer do colo do útero na prevalência dos resultados citológicos em função da idade da mulher e do intervalo entre os controles. MÉTODOS: Foi analisado o banco de dados de um laboratório central de citopatologia. O estudo incluiu 2.002.472 testes obtidos de mulheres previamente rastreadas e 217.826 testes obtidos de mulheres não previamente rastreadas. A Razão de Prevalência (RP) com um intervalo de confiança de 95% foi calculada para os resultados de testes de mulheres rastreadas em relação aos testes de mulheres não rastreadas, em função da idade. O laboratório utiliza o Sistema de Bethesda desde 1998, mas ainda subdivide o resultado Lesão Intraepitelial de Alto Grau (HSIL) em dois níveis: HSIL-CIN 2 e HSIL-CIN 3. RESULTADOS Para HSIL, a RP dos testes de mulheres rastreadas em relação aos testes de mulheres não rastreadas foi de 0,97 (0,83-1,13) em mulheres abaixo de 20 anos e 0,99 (0,86-1,14) para mulheres entre 20 e 24 anos, diminuindo significativamente em mulheres entre 25 e 29 anos (RP 0,63, 0,52-0,76). As RP para o carcinoma espinocelular (SCC), adenocarcinoma in situ (AIS) e adenocarcinoma invasivo apresentaram uma redução significativa em todos os grupos etários acima de 30 anos. Para o grupo etário 30 a 59 anos, a proteção conferida pelo rastreamento para SCC, AIS e adenocarcinoma invasivo foi de 83% ou mais, para intervalos de realização dos exames entre 1 e 5 anos. Para mais de cinco anos de intervalo, o efeito protetor oferecido para SCC foi de 50%. Nas mulheres não previamente rastreadas, a prevalência de lesões intraepiteliais de baixo grau (LSIL) e HSIL-CIN 2 diminuíram com a idade, enquanto que para HSIL-CIN 3 a prevalência aumentou. Ainda nesse grupo de testes, a prevalência de HSIL-CIN 2 foi maior do que a de HSIL-CIN 3 para mulheres de até 29 anos (RP = 4,73, 3,90-5,75) e mais baixa para os grupos de 30 a 49 anos (RP = 0,66, 0,50-0,87) e 50 anos ou mais (RP = 0.21,0.12-0.36). No grupo de testes de mulheres rastreadas, a prevalência de HSIL-CIN 2 foi maior nas faixas etárias até 29 anos (RP = 2,72, 2,49-2,97). CONCLUSÕES O rastreamento citológico reduziu a prevalência dos diagnósticos citológicos de HSIL, CEC, AIS e adenocarcinoma invasivo. Um intervalo de 3 anos para a realização dos controles foi apropriado para reduzir os resultados citológicos. O perfil da prevalência de HSIL-CIN 2 se assemelha ao padrão de prevalência de LSIL e foi mais prevalente do que HSIL-CIN 3 em mulheres jovens. O impacto do rastreamento foi menos evidente quando HSIL foi sugestivo de CIN 2. O rastreamento citológico em mulheres abaixo de 25 anos deve ser criteriosamente avaliado Abstract: BACKGROUND Cervical cytology still is the cervical cancer screening test for women more used. Even though there is no doubt about the impact of cytology screening on invasive squamous cervical cancer, this issue is not as clear for squamous lesions on young women and for invasive adenocarcinoma. Moreover this protective effect varies according to interval tests. HPV testing is not recommended for women under age 30, and the carefully analysis of the performance of screening on this age group can help physicians to qualify their approach. OBJECTIVE To evaluate the impact of cervical cytology screening on the prevalence of cervical cytological results in women, as a function of age and the interval between tests. METHODS A central cytopathology laboratory database for cervical screening was analyzed. It included cytology screening data of 2.002.472 tests obtained from previously screened women and 217.826 tests from unscreened women. A prevalence ratio (PR) with a 95% confidence interval for screened women was calculated, in relation to unscreened women, as a function of age. The laboratory has been using the Bethesda System since 1998, but maintain the sub-categorization of HSIL in two levels: HSIL-CIN 2 and HSIL-CIN 3. RESULTS For high-grade squamous intraepithelial lesion (HSIL), the PR was 0.97 (0.83-1.13) for women aged 20 or younger and 0.99 (0.86-1.14) for women aged 20-24 years, decreasing significantly in women aged 25-29 years (PR 0.63, 0.52-0.76). The PR for squamous cell carcinoma (SCC), adenocarcinoma in situ (AIS) and invasive adenocarcinoma showed a significant reduction in all age groups over 30 years. For the age group ranging from 30-59 years, protection conferred by screening for SCC, AIS and invasive adenocarcinoma was 83% or higher for screening intervals ranging from 1-5 years. For 5-year intervals or longer, the protective effect offered for SCC was 50%. For unscreened women, the prevalence of Low Grade Intraepithelial Lesions (LSIL) and HSIL-CIN 2 decreased with age, whereas HSIL-CIN 3 prevalence increased. The prevalence of HSIL-CIN 2 was higher than that of HSIL-CIN 3 for women up to 29 years (PR=4.73, 3.90-5.75) and lower for age groups 30-49 years (PR=0.66, 0.50-0.87) and 50 years or more (PR=0.21,0.12-0.36). For screened women, the prevalence of HSIL-CIN 2 was also higher in age groups up to 29 years (PR=2.72, 2.49-2.97). CONCLUSIONS Cytology screening reduced the prevalence of HSIL, SCC, AIS and invasive adenocarcinoma cytological results. A three-year interval was appropriate for the reduction of these lesions. HSIL-CIN 2 resembles the prevalence pattern of LSIL and was more prevalent than HSIL-CIN 3 in younger women. The impact of screening was less evident when HSIL is suggestive of CIN 2. Cervical cytology screening in women 25 or younger should be critically evaluated Doutorado Oncologia Ginecológica e Mamária Doutora em Ciências da Saúde

The objective was to describe the cervical cancer cases in Brazil by the age-group and stage at diagnosis, and to associate them with the human development index (HDI), where the women live. This was a retrospective study that used data from the Brazilian hospital-based cancer registry from 2005 to 2014. The data were accessed by 5-year age/groups and the federal units. The association between the proportion of cases at Stage I and HDI was estimated in an adjusted linear regression analysis. Among the staged cases, the proportions of cases diagnosed at FIGO Stage I, II, III and IV were 21.2%, 30.7%, 39.9% and 8.2%, respectively. The cases were diagnosed mostly in women aged 45-49 years. There was a significant increase in the proportion of Stage I cases with an increasing HDI (coefficient, 0.46; 95% confidence interval, 0.17-0.76). In conclusion, most of the cases were diagnosed at late stages. The stage at the diagnosis was associated with the human development level Fechado

Evidence-based clinical guidelines ensure best practice protocols are available in health care. There is a widespread use of human papillomavirus deoxyribonucleic acid (HPVDNA) tests in Brazil, regardless of the lack of official guidelines. On behalf of the Brazilian Association for the Lower Genital Tract Pathology and Colposcopy (ABPTGIC, in the Portuguese acronym), a team of reviewers searched for published evidence and developed a set of recommendations for the use of HPV-DNA tests in cervical cancer screening in Brazil. The product of this process was debated and consensus was sought by the participants. One concern of the authors was the inclusion of these tests in the assessment of women with cytologic atypia and women treated for cervical intraepithelial neoplasia (CIN). Testing for HPV is recommended in an organized screening scenario to identify women with precursor lesions or asymptomatic cervical cancer older than 30 years of age, and it can be performed every 5 years. It also has value after the cytology showing atypical squamous cells of undetermined significance (ASC-US) or low-grade squamous intraepithelial lesions (LSILs) as a triage test for colposcopy, in the investigation of other cytological alterations when no abnormal findings are observed at colposcopy, seeking to exclude disease, or, further, after treatment of high-grade cervical intraepithelial neoplasia, to rule out residual disease. Resumo O uso de diretrizes clínicas baseadas em evidências visa assegurar as melhores práticas na área de cuidado à saúde. O uso de testes de ácido desoxirribonucleico de papilomavírus humano (DNA-HPV) vem crescendo e se disseminando sem que existam recomendações de uso no cenário brasileiro.Emnomeda Associação Brasileira de Patologia doTrato Genital Inferior e Colposcopia (ABPTGIC), grupos de revisores pesquisaram evidências e formularamrecomendações para o uso dos testes de DNA-HPV no rastreamento do câncer do colo do útero, no seguimento de mulheres com atipias citológicas, e após tratamento de neoplasia intraepitelial cervical (NIC). O produto desse processo foi debatido e foi buscado consenso entre participantes. Os testes de DNA-HPV são recomendados num cenário de rastreamento organizado para identificação de mulheres portadoras de lesões precursoras ou câncer assintomático com mais de 30 anos e podem ser realizados a cada 5 anos. Também têm valor após a citologia mostrando células escamosas atípicas de significado indeterminado (ASC-US) ou lesão intraepitelial escamosa de baixo grau (LSIL) como teste de triagempara colposcopia, na investigação de outras alterações citológicas quando não são observados achados anormais à colposcopia, buscando excluir doença, ou, ainda, no seguimento após tratamento das neoplasias intraepiteliais de alto grau, para exclusão de doença residual.

Cervical adenocarcinoma is associated with a poor prognosis, which may be caused by the infiltrative growth pattern and metastasis of tumor cells. There is a lack of consensus on hysterectomy after radiotherapy for the improvement of selected cases. The present study aimed to assess the oncological outcome of post-radiotherapy hysterectomy in females with cervical adenocarcinoma. A total of 39 females with cervical adenocarcinoma at stages IB1 to IIIB, managed primarily with radiotherapy with complete response, and underwent extrafascial hysterectomy as consolidation therapy between 1988 to 2015 were studied. Surgery complications and residual disease were evaluated. A comparison group was constructed, comprising 41 females with cervical adenocarcinoma managed with exclusive radiotherapy or chemoradiotherapy demonstrating complete response, without surgery. Descriptive and survival analysis was performed. The groups were comparable in terms of age, cancer stage, radiotherapy (dose and duration) and follow-up, although 67% of hysterectomies were performed prior to 2002 and 46% of the radiotherapy group received chemoradiation. Late complications were similar. There were nine recurrences (23%) in the case series and 10 recurrences (24%) in the radiotherapy group. Residual disease was detected in 56% (22/39) of uterine specimens, of which 12 were up to 10 mm. Residual disease was associated with recurrence (31% vs. 6%, P=0.028). The overall survival rate was 75% for the case series vs. 88% for the radiotherapy group (P=0.579), and the disease-free survival rate was 79-80% for both. Removal of residual disease by hysterectomy did not improve the overall survival rate (P=0.283) and disease-free survival rate (P=0.072). Post-radiotherapy hysterectomy in cervical adenocarcinoma is a feasible procedure with acceptable complications, however, it did not bring relevant benefits in recurrences, disease-free survival, and overall survival rates.

The present study aimed to assess the diagnosis, treatment and follow-up of uterine sarcoma cases. A retrospective cohort study with 122 women recruited between 2001 and 2016 was performed. The data regarding epidemiology, clinical presentation, treatment and follow-up were analyzed based on the following histological types: Carcinosarcoma, leiomyosarcoma, endometrial stromal sarcoma (ESS) and adenosarcoma. Statistical analysis included descriptive statistics, logistic regression and survival curves. The diagnosis of uterine sarcoma exhibited an increasing trend of +1.2 new cases every 2 years (P=0.044) and comprised 10% of all uterine cancer diagnoses. There were 47% carcinosarcomas, 22% leiomyosarcomas, 16% ESS and 14% adenosarcomas. The majority of the women was ≥60 years old (62%). Among the subjects, 77% were postmenopausal, 61% had a body mass index up to 29.9 kg/m
2 and 71% presented with a comorbidity. Regression analysis exhibited an association between post menopause and the histological type associated with lower overall survival (OS), namely leiomyosarcoma or carcinosarcoma (odds ratio, 5.45, P<0.001). Stage I malignancy was present in 44% and Stage IV in 22%. The treatment included primary surgery in 78% of the cases, whereas 79% received adjuvant therapy. Only 55 cases achieved disease control and 20 relapsed (36%) with a 5-year OS rate of 33%. The OS was lower for carcinosarcoma and leiomyosarcoma (20%; P=0.003). In summary, the present study indicated that the number of uterine sarcoma cases had increased between 2001 and 2016. The majority of the women were >60 years old and diagnosed in advanced stages. The postmenopausal status was associated with histological types of poor prognosis. The OS was low and worse for patients with carcinosarcoma and leiomyosarcoma. [ABSTRACT FROM AUTHOR]- Published

Orientador: Julio Cesar Teixeira Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: Introdução: O câncer de colo uterino é a quarta neoplasia mais incidente no mundo e a terceira no Brasil. Apesar das altas taxas de incidência e mortalidade é altamente prevenível com vacinação e rastreamento adequados. No município de Indaiatuba (SP), o Programa PREVENTIVO, que contempla rastreamento organizado com teste HR-HPV pelo SUS, foi instituído em outubro/2017. Até o início da pandemia COVID-19, em março/2020, alcançou melhora expressiva na cobertura, com taxas de rastreamento de 88,8%. Com o início da pandemia e fechamento temporário das UBS, as taxas do programa apresentaram queda significativa e a cobertura do rastreamento para câncer do colo uterino no programa vem apresentando dificuldades de retorno no período após a pandemia. Objetivos: Avaliar o impacto da pandemia COVID-19 no Programa PREVENTIVO no município de Indaiatuba (SP) através da estimativa da cobertura nos períodos anterior, durante e após a pandemia e correlacioná-la por grupos de faixa etária. Sujeitos e métodos: Estudo de corte transversal que avaliou os resultados dos testes realizados em estudo de demonstração, de base populacional, do programa PREVENTIVO do município de Indaiatuba (SP). O controle do programa não permite duplicação de testes. Foram avaliadas a evolução do número de testes mensais realizados no período de outubro/2017 a fevereiro/2022, 54 meses da primeira rodada e por faixas etárias (25-34, 35-49 e 50 anos ou mais), com cálculo de tendência linear e p

Orientadores: Egberto Ribeiro Turato, Fernanda Garanhani de Castro Surita Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: Introdução: Lidar com a realidade da gravidez na adolescência envolve lidar com contradições e conflitos na prática clínica, que vão além de protocolos clínicos de atenção. É nesse contexto conflituoso que os profissionais de saúde trabalham sua assistência às gestantes adolescentes e são cobrados a estarem aptos a lidar da melhor forma com tais conflitos. Conhecer a perspectiva destes profissionais diante do diário enfrentamento deste contexto é fundamental para aprimorar a estratégia clínica de atenção à gestante. Objetivo: Explorar os significados psicológicos atribuídos pelos profissionais de saúde ao trabalho assistencial junto à gestante adolescente, a partir da estrutura padrão de trabalhos qualitativos publicados internacionalmente na literatura biomédica. Método: Foram realizados dois estudos suplementares: um bibliométrico e um de campo. Para o estudo bibliométrico, foi realizado um mapeamento da literatura biomédica e uma análise bibliométrica. Sete pesquisadores trabalharam em diferentes fases do processo. Foram incluídos estudos que se referiam a "qualitative study" em seu conteúdo, durante um período de seis meses. Para o estudo de campo, foi utilizado o Método Clínico-Qualitativo. A amostra foi intencional e internamente homogênea, composta por médicos residentes em ginecologia e obstetrícia, bem como as equipes de enfermagem, serviço social e psicologia. A amostra foi fechada pelo critério de exaustão. Foram realizadas 18 entrevistas individuais, semidirigidas de questões abertas em profundidade. Os dados foram analisados através da técnica de Análise de Conteúdo Clínico-Qualitativa. Resultados: Como resultados da pesquisa bibliométrica, 1725 estudos foram selecionados. Cinco revistas foram responsáveis por 12,1% de todas as publicações. Os temas de saúde com maior número de publicações incluíram Gestão da Saúde (12%) e Saúde da Mulher (9,8%), enquanto os autores dos estudos tiveram afiliação acadêmica em 76 países diferentes. O tamanho da amostra foi de 11 a 20 participantes (27,13%) e o referencial da Grounded Theory (9,04%), sem mencionar o uso de software (95,3%). Como resultados da pesquisa de campo, foram trabalhados dois grandes temas relacionados à psicodinâmica dos profissionais: a organização do trabalho e o manejo subjetivo. Em relação à organização do trabalho, surgiram três categorias: "Equipe multidisciplinar: Uma faca de dois gumes", "Ambulatório de Pré-natal de Adolescentes: função de treinamento ou de cuidado?", "Quando o protocolo frustra". Em relação ao manejo subjetivo, os resultados encontram-se em construção. Conclusões: A estruturação aprimorada de uma pesquisa qualitativa amplia a comunicação efetiva entre profissionais de saúde e pesquisadores, apoiando, portanto, o gerenciamento de situações clínicas. As conclusões da pesquisa de campo compreendem as relações interpessoais entre profissionais da saúde e adolescentes, bem como o manejo não protocolar dos casos com estas gestantes. A assistência às adolescentes grávidas envolve conflitos, os quais podem ser melhor trabalhados com o suporte de uma organização do trabalho de pré-natal mais efetiva. Isso se reflete diretamente na forma como se maneja clinicamente as diversas demandas emocionais e sociais das adolescentes grávidas Abstract: Introduction: Dealing with the reality of pregnancy in adolescence involves contradictions and conflicts in clinical practice, which go beyond clinical care protocols. In this conflicting context, health providers work with pregnant adolescent and they are required to be able to deal with such dilemmas. Knowing the perspective of these professionals facing the daily confrontation of this context is essential to improve the clinical strategy of attention to pregnant adolescents. Objective: To explore the psychological meanings attributed by health professionals to work with pregnant adolescents, based on the standard structure of qualitative studies published internationally in the biomedical literature. Method: Two different studies were performed: bibliometric and field study. For the bibliometric study, a biomedical literature mapping and bibliometric analysis were performed. Seven researchers worked at different stages of the process. We included studies that referred to "qualitative study" in its content over a six-months period. For the field research, the Clinical Qualitative Method was used. The sample was intentional and homogeneous, composed of medical residents in gynecology and obstetrics, as well as nursing, social work and psychology teams. The sample was closed by the exhaustion criterion. Eighteen Individual in-depth interviews were conducted. Data were analyzed using the Clinical Qualitative Content Analysis technique. Results: As a result of bibliometric research, 1725 studies were selected. Five journals accounted for 12.1% of all publications. The heath themes with the most publications included Health Management (12%) and Women's Health (9.8%), while the authors of the studies had academic affiliation in 76 different countries. The sample sizes were between 11 and 20 participants (27.13%) and the Grounded Theory framework (9.04%) stood out. As a result of the field research, two major themes emerged from the content analysis and they are related to the psychodynamics of health professionals: work organization and subjective handling. Regarding the organization of work, three categories emerged: "Multidisciplinary Team: A double-edged sword", "Adolescent Prenatal Outpatient Unit: Training or Care?", "When the protocol frustrate". Regarding subjective handling, the results are under construction. Conclusions: The improved structuring of qualitative research extends effective communication between health professionals and researchers, thus supporting the management of clinical situations. The conclusions of the field research include the interpersonal relation between health professionals and adolescents, as well as the non-protocol handling of cases with pregnant women. Pregnant adolescents care involves conflicts, which can best be managed with the support of a more effective prenatal work organization. This is directly reflected in the clinical handling of the emotional and social demands of pregnant adolescents Doutorado Saúde Materna e Perinatal Doutor em Ciências da Saúde CAPES 001

Orientadores: Marco Antonio Garcia de Carvalho, Guilherme Palermo Coelho Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Tecnologia Resumo: O Câncer de Colo de Útero (CCU) é um problema de saúde coletiva em todo o mundo, nesse sentido foram feitos grandes avanços para sua detecção e prevenção. Apesar dos esforços feitos pelos países da América Latina para reduzir os indicadores de mortes por essa doença, eles ainda não são suficientes em comparação com o progresso de outros países europeus.Uma das razões, é que os sistemas de saúde pública em vários países da América têm limitações importantes em seus programas de acompanhamento e prevenção.O vírus do papanicolau está associado a 95 % dos cânceres cervicais, embora as instituições de saúde pública em todo o mundo invistam esforços técnicos, humanos e econômicos para reduzir o impacto da CCU em suas comunidades. Desde 1960, são realizadas pesquisas a respeito ao exame do Papanicolau, considerado este como um dos mecanismos mais utilizados pelo mundo para controlar e diagnosticar esta doença. Alterações Associadas à Malignidade (MAC), são pequenas alterações na morfologia e textura da cromatina, predizendo possíveis lesões malignas associadas ao CCU, tornando-se uma investigação interessante na aplicação do exame do panicolau. A identificação de MAC¿s em imagens de células cervicais é um problema accessível a possíveis investigações, devido às complexidades da identificação visual de estruturas nucleares. A partir das técnicas de Processamento Digital de Imagens (PDI), tem se conseguido grandes avanços, especialmente na obtenção de 400 descritores para o estudo de MAC's, no entanto a pequena quantidade de imagens focadas no estudo MAC, assim como a limitação técnica do equipamento e poucos profissionais que trabalham nesses estudos limitam o progresso nesta área. Esta tese tem como objetivo, otimizar descritores propostos na literatura para o estudo do MAC utilizando PDI. Para atingir este objetivo, foi criado em conjunto com a Fundação Universitária de Ciências para a Saúde da Colômbia (FUCS), um Data set de imagens de células cervicais que possibilitará o estudo de MAC's. Para adquirir imagens para o estudo, foram digitalizadas 6 folhas de pacientes com diferentes patologias que foram diagnosticadas e marcadas por uma cito-técnica especializada. As imagens foram pré-processadas empregando filtros espaciais e núcleos segmentados usando o algoritmo k-means e watershed. Os canais de cor foram separados pela sua contribuição de hematoxilina e corante Orange G6 dos núcleos segmentados; se extraíram 800 descritores morfológicos, de textura, densidade óptica e iluminação dos núcleos para sua posterior classificação. Contribuímos com a criação de um conjunto de dados para o estudo do MAC em imagens de CCU de exames de citologia convencional. Comparamos três classificadores supervisionados, treinados com 795 descritores, 412 descritores, 200 descritores e 962 instâncias. Calculamos e ordenamos os descritores extraídos pela informação obtida de cada um deles. Com um grupo de descritores, a precisão da classificação é 95,3 %. A segmentação dos núcleos mostrou uma precisão de 85,6 %. A otimização dos descritores foi de 4,3% melhor que a dos descritores propostos pela literatura, sendo composta por 30% de descritores de textura, 27% de descritores morfológicos, 11,5% de descritores de densidade óptica e 17% de descritores associados à concordância de níveis de cinza Abstract: Cervical cancer (CCU) is a collective health problem worldwide, in that sense great advances have been made for its detection and prevention. Despite the efforts made by Latin American countries to reduce the indicators of deaths from this disease, they are still not sufficient compared to the progress of other European countries. One of the reasons is that the public health systems of several countries in the Americas present important limitations in their monitoring and prevention programs. The Human Papilloma Virus is associated with 95% of cervical cancers. Public health institutions around the world invest technical, human, and economic efforts to lessen the impact of the CCU on their communities. The mechanism most used by the world to control and diagnose this disease is the examination of the Human Papilloma. Research on this test has been conducted since 1960. The Malignancy Associated Changes MAC, are slight alterations in the morphology and texture of chromatin predicting possible malignant lesions associated to CCU, becoming one of the promising researches to be applied in the examination of the human papilloma. The identification of MAC's in cervical cell images is an open problem, due to the complexities of visual identification of nuclear structures. From Digital Image Processing (DIP) techniques great advances have been made especially in obtaining 400 descriptors for the study of MAC's, however the small amount of images focused on MAC's study, as well as the technical limitation of the equipment and few professionals who worked to these studies has limited progress in this area. The objective of this thesis is to optimize the descriptors proposed in the literature for the study of MAC using DIP. In order to achieve this objective, a set of cervical cell images was created for the study of MAC's, in conjunction with the Fundación Universitaria de Ciencias para la Salud-Colombia (FUCS). With the purpose of acquiring images for the study, 6 slides of patients with different pathologies were digitalized, which were diagnosed and labeled by a specialized cyto-technique. The images were pre-processed using spatial filters and segmented nuclei using the k-means and watershed algorithm. The color channels were separated by contribution of Hematoxylin and Orange G6 dye from the segmented nuclei; 800 morphological, texture, optical density and illumination descriptors were extracted from the nuclei for later classification. We contributed with the creation of a Data Set for the study of MAC in CCU images of conventional cytology examinations. We compared three supervised classifiers with 795 descriptors, 412 descriptors, 200 descriptors and 962 instances. We calculated and sorted the extracted descriptors by the information gain of each one of them. The optimization of the descriptors was 4.3% better than the descriptors proposed in the literature, consisting of 30% texture descriptors, 27% morphological descriptors, 11.5% optical density descriptors and 17% descriptors associated with the agreement of gray levels Doutorado Sistemas de Informação e Comunicação Doutor em Tecnologia CAPES

Orientadores: Cassio Cardoso Filho, Rosana Onocko Campos Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: O câncer de mama é o tipo mais frequente entre as mulheres, depois do câncer de pele não melanoma. Estima-se que 28% dos novos casos diagnosticados de câncer serão de mama, que também acomete os homens, porém, representando apenas 1% do total de casos da doença. Estatísticas indicam aumento da sua incidência, tanto nos países desenvolvidos quanto nos em desenvolvimento. Objetivou-se analisar o acesso ao cuidado do câncer de mama, na percepção (recordatório) dos usuários do Sistema Único de Saúde (SUS). Parte dos dados, obtidos em etapas anteriores do "Inquérito sobre o acesso a partir da atenção básica, o funcionamento e a utilização da atenção especializada para quatro condições traçadoras em quatro grandes cidades brasileiras", subsidiou a presente investigação, tendo como local de estudo a cidade de Campinas, SP. Tratou-se de pesquisa quantitativa, transversal, a partir de amostragem não probabilística. A população de estudo para a traçadora "câncer de mama" foi definida como sendo o conjunto de pacientes atendidas em consultas médicas nas unidades de saúde de atenção especializada e encaminhadas pela atenção básica (AB). As usuárias foram entrevistadas em dois serviços de atenção terciários: Centro de Atenção Integral à Saúde da Mulher (CAISM) e Hospital Municipal Dr. Mário Gatti (HMMG), entre maio e setembro de 2016, respondendo questionário de múltipla escolha, composto por 52 questões. A análise do conjunto de dados obtidos foi processada nos aplicativos Microsoft Excel e Office 2000, tabulação das respostas e estudo das frequências absolutas, e SPSS 20.0 para Windows, análises descritivas e de associação entre as variáveis estudadas. Através da análise estatística das variáveis envolvidas, foi possível compreender o modelo de organização da atenção, planejada para racionalizar o acesso dos pacientes aos serviços médicos, mas que tem obstáculos a serem superados pelos usuários e equipe de saúde. A amostragem incluiu 318 indivíduos, o que correspondeu ao total de questionários validados no inquérito. As mulheres entrevistadas, em tratamento para câncer de mama nos dois serviços se autodeclararam brancas (57%), com média de idade de 59 anos (19-93 anos) e escolaridade distribuída entre ensino fundamental (54%) e médio (26%). Das pacientes afetadas pela doença, 74,3% estão na faixa etária acima dos 50 anos. Apenas 8% das mulheres possuíam plano de saúde. Os resultados evidenciam que, em Campinas, há vínculo compartilhado entre AB e Serviço Especializado no cuidado às pacientes, mas a comunicação entre os serviços apresenta fragilidades. Os tempos de espera para exames complementares, bem como o acesso às consultas e ao tratamento atendem minimamente aos prazos e parâmetros preconizados em portarias ministeriais. Reduzir os tempos de espera ainda se coloca como desafio para o Gestor Público em Saúde, diante do aumento de novos casos e da necessidade de uma gestão de casos mais integrada e abrangente. Os dados demonstram que a cidade de Campinas caminha para a efetivação dos preceitos das políticas públicas, embora necessitando aprimorar fluxos na rede de cuidados aos pacientes oncológicos, visando agilidade no acesso e no início de tratamento Abstract: Breast cancer is the most common cancer among women in Brazil and in other countries, after non-melanoma skin cancer. It's estimated that about 28% of newly diagnosed cancers will be breast cancers. It also affects men, but it represents only 1% of the total cases of the disease. Statistics show an increase incidence in both developed and developing countries. The objective of this study was to analyze the access to basic medical care, the operation and the use of specialized medical care using the breast cancer as a tracer in the city of Campinas-SP. The data from the study "Survey on access to basic care, the operation and use of specialized care for four tracing conditions in four large Brazilian cities" were analyzed. Part of the data obtained in previous stages of this project subsidized the present investigation, which was limited to analyzing the breast cancer as a tracer in the city of Campinas-SP. It is a quantitative research, transversal, from a non-probabilistic sampling. The study population was defined as the set of patients attended in medical consultations in specialized health care units and referred by primary care. Users were interviewed in two tertiary care centers - "Centro de Atenção Integral a Saúde da Mulher (CAISM)" and "Hospital Municipal Dr. Mário Gatti (HMMG)" - between May and September/2016 and answered a questionnaire with 52 questions. The analysis of the data was processed using the software Microsoft Excel and Office 2000 for tabulation the responses and to analyze of the absolute frequencies and SPSS 20.0 for Windows for later statistical analysis including descriptive and association analyzes among the studied variables. Through the statistical analysis of the variables involved, it was possible to understand the organization model of medical care, planned to rationalize the patient access to medical services, but also has obstacles to be overcome by patients and medical staff. The sampling included 318 individuals, which corresponds to the number of validated answers in the survey. The women interviewed in treatment for breast cancer in both services considered themselves white (57%), with a mean age of 59 + 14 years (19-93 years) and schooling distributed between middle (54%) and high school (26%). The majority of affected patients were over 50 years old (74,3 %) and only 8% of the women had health insurance coverage. With the results we can say that in Campinas there is a shared bond between Basic Medical Care, Specialized Medical Care and patients with breast cancer, but the communication between the medical services still presents fragilities. The waiting times for complementary tests and access to appointments and therapy minimally meet the deadlines and parameters recommended in Ministerial Order. Reducing these waiting times remains a challenge for Public Health Managers in the face of the increase in new cases of breast cancer and the need for more integrated and comprehensive case management. The collected data show that the city of Campinas steps to implementing recommended principles of public policies for breast cancer aid, although it is necessary to improve flows in the network care for cancer patients, aiming at agility in access and to start treatment Mestrado Política, Planejamento e Gestão em Saúde Mestra em Saúde Coletiva

Orientador: Júlio César Teixeira Tese (doutorado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: Introdução: O câncer de colo de útero é uma das neoplasias malignas mais comuns entre mulheres e uma importante causa de morte nesse grupo, principalmente nos países menos desenvolvidos. Dentre outros fatores, a existência de métodos eficazes de rastreamento permite, além da detecção de lesões precursoras, a detecção da doença em estádios iniciais como os carcinomas microinvasores de colo uterino. Quando esta neoplasia é diagnosticada nestes estádios, existe a possibilidade da realização de tratamentos conservadores, especialmente em mulheres com desejo reprodutivo. A despeito do tratamento adequado, alguns casos evoluem com recidiva da doença, demonstrando a necessidade da identificação dos fatores histopatológicos que predispõem ou aumentam este risco. Objetivos: avaliar a taxa de recidiva do carcinoma microinvasor do colo do útero (MIC) estádio IA1 do tipo epidermoide em seguimento de longo prazo de acordo com o tipo de tratamento realizado, se conservador ou não do útero. Em uma casuística ampliada, analisar os critérios histopatológicos relacionados à segurança oncológica do tratamento conservador do MIC estádio IA1.

Orientador: Luiz Carlos Zeferino Dissertação (mestrado) - Universidade Estadual de Campinas, Faculdade de Ciências Médicas Resumo: O câncer do colo do útero é uma doença neoplásica maligna muito frequente, porém evitável. Foram estimados 528.000 casos novos da doença no mundo, no ano de 2012. No Brasil, a estimativa para 2018 é de 16.370 casos novos da doença. O desenvolvimento de ferramentas clínicas para apoio diagnóstico, terapêutico e seguimento das neoplasias malignas pode qualificar o cuidado em benefício da paciente. A proteína SOD2 faz parte da família de metaloenzimas atuantes no sistema celular antioxidante por catalisar a conversão do ânion de superóxido (O2-) em peróxido de hidrogênio (H2O2) em um processo conhecido como dismutase. A maioria dos estudos sobre a expressão de SOD2 e o câncer mostra que a superexpressão dessa enzima está associada com a presença de metástase e um mau prognóstico em muitas doenças malignas. Desta forma, este estudo teve como objetivo avaliar se a expressão da proteína SOD2 está associada com o prognóstico do carcinoma do colo do útero avançado. Metodologia: Trata-se de uma coorte cuja amostra foi constituída a partir das mulheres incluídas no ensaio clínico prospectivo Concomitant cisplatin plus radiotherapy and high-dose-rate brachytherapy versus radiotherapy alone for stage IIIB epidermoid cervical cancer: a randomized controlled trial, conduzido no Hospital da Mulher Prof. Dr. José Aristodemo Pinotti, Universidade Estadual de Campinas (UNICAMP), Brasil. No total, 147 mulheres foram incluídas, 72 mulheres no grupo que recebeu cisplatina concomitante a radioterapia (QT/RT) e 75 mulheres no grupo que recebeu apenas radioterapia (RT) e foram seguidas por sete anos. A amostra deste estudo foi constituída por 63 mulheres que ainda dispunham de blocos com material suficiente para reanálise com hematoxilina e eosina (HE) e os ensaios imuno-histoquímicos. A avaliação da expressão da SOD2 pela imuno-histoquímica baseou-se no percentual de células coradas e na intensidade da coloração, analisados separadamente e juntos utilizando um score. As analises do percentual de células coradas foram realizadas em três pontos de corte (50%, 75% e 90% de células coradas), e cada ponto de corte avaliado gerou um score específico, categorizado como alto e baixo. Dados de recidiva e óbito foram comparados com os da avaliação imuno-histoquímica. As curvas da sobrevida livre de doença e sobrevida global foram avaliadas por Kaplan-Meier e Log-rank. Fatores associados às sobrevidas foram analisados pela regressão de Cox. Resultados: A intensidade da coloração analisada separadamente e junto com o percentual de células coradas para qualquer ponto de corte estão associados com a recorrência. Casos com mais de 90% de células coradas e com alto score de 75% estão associados com óbito também. O alto score de 90% foi associado com a recidiva, recidiva sistêmica e o óbito. Sobrevida livre de doença e sobrevida global foram piores em mulheres cujo carcinoma teve mais de 90% de células coradas e naqueles com alto score de 75% e 90%. Conclusão: A forte intensidade de coloração e o alto percentual de células coradas para a proteína SOD2 estão relacionados com a recorrência e também com a sobrevida global de carcinoma do colo do útero estádio IIIB Abstract: Cervical cancer is a very common malignant neoplastic disease, however avoidable. Were estimated 528.000 new cases diagnosed each year worldwide. In Brazil, for 2018, it is estimated 16.370 new cases of the disease. The development of clinical tools for diagnosis, treatment and for follow-up support of malignant neoplasms may qualify the outcome, benefiting the patients. The protein SOD2 is part of the family of metalloenzymes acting in the antioxidant cell system by catalyzing the conversion of the superoxide (O2-) anion into hydrogen peroxide (H2O2) in a process known as dismutase. Most studies on SOD2 expression and cancer showed that the high expression of this protein is associated with the presence of metastasis and a poor prognosis in many malignancies. The aim of this study was to evaluate whether SOD2 protein expression is associated with the prognosis of cervical carcinoma stage IIIB. Methodology: This study selected patients from a cohort consisting of tumor samples from women included in the prospective clinical trial Concomitant cisplatin plus radiotherapy and high-dose-rate brachytherapy versus radiotherapy alone for stage IIIB epidermoid cervical cancer: a randomized controlled trial, conducted at the Women's Hospital Prof. Dr. José Aristodemo Pinotti, State University of Campinas (UNICAMP), Brazil. Of the 147 women included, 72 received cisplatin concomitantly with radiotherapy (CRT) and 75 women received radiotherapy alone (RT) and were followed-up to seven years. The sample of this study consisted of 63 women who had available blocks to reanalysis with hematoxylin and eosin (HE) and immunohistochemistry assay. The evaluation of SOD2 expression by immunohistochemistry assay was based on the percentage of stained cells and the staining intensity, analyzed separately and together by a score. The analyses of the percentage of stained cells was performed using three cut points (50%, 75% and 90% of stained cells), and each cut point generating a specific score, categorized as high and low. Relapse and death data were compared to immunohistochemistry evaluation. Disease-free survival and overall survival curves were performed using the Kaplan-Meier method and the log-rank test. Factors associated with the survivals were analyzed by Cox Proportional Hazards Regression. Results: The intensity of staining analyzed separately and together to percentage of cells stained for any cut-off point are associated with recurrence. Cases with more than 90% stained cells and with high 75% score was also associated with death. High 90% score was associated with recurrence, distant recurrence and death. Disease-free survival and overall survival were worse in women whose carcinoma had more than 90% stained cells and those with high 75% score and 90% score. Conclusion: Strong intensity and high percentage of stained cells for SOD2 protein it is related to relapse and overall survival of squamous cell carcinoma of the cervix IIIB Mestrado Oncologia Ginecológica e Mamária Mestra em Ciências da Saúde CNPQ 304299/2014-6 CAPES

- Abstract
Objective: To describe Top-hat results and their association with margin status and disease relapse in a referral facility in Brazil., Methods: A retrospective study of 440 women submitted to LEEP to treat HSIL, in which 80 cases were complemented immediately by the top hat procedure (Top-hat Group - TH). TH Group was compared to women not submitted to Top-hat (NTH). The sample by convenience included all women that underwent LEEP from January 2017 to July 2020. The main outcome was the histological result. Other variables were margins, age, transformation zone (TZ), depth, and relapse. The analysis used the Chi-square test and logistic regression., Results: The TH Group was predominantly 40 and older (NTH 23.1% vs. TH 65.0%, p<0.001). No difference was found in having CIN2/CIN3 as the final diagnosis (NTH 17.0% vs. TH 21.3%, p=0.362), or in the prevalence of relapse (NTH 12.0% vs. TH 9.0%, p=0.482). Of the 80 patients submitted to top hat, the histological result was CIN2/CIN3 in eight. A negative top hat result was related to a negative endocervical margin of 83.3%. A CIN2/CIN3 Top-hat result was related to CIN2/CIN3 margin in 62.5% (p=0.009). The chance of obtaining a top hat negative result was 22.4 times higher (2.4-211.0) when the endocervical margin was negative and 14.5 times higher (1.5-140.7) when the ectocervical margin was negative., Conclusion: The top hat procedure did not alter the final diagnosis of LEEP. No impact on relapse was observed. The procedure should be avoided in women of reproductive age., Competing Interests: Conflicts to interest: none to declare., (© 2024.

- Abstract
Background: Cervical cancer is a preventable disease, and the Brazilian screening is opportunistic and has low impact. The current study evaluated an initiative to organize screening using DNA-HPV testing as a replacement for cytology., Methods: This demonstration study examined information from 16 384 DNA-HPV tests for screening in women aged 25-64 years from Indaiatuba city between October 2017-March 2020. The comparison was 20 284 women screened using cytology between October 2014-March 2017. The flowchart indicates the repetition of a negative test in five years. HPV16- and/or HPV18-positive tests and the 12 pooled high-risk HPV-positive tests with abnormal liquid-based cytology were referred for colposcopy. If cytology was negative, the HPV test was repeated in 12 months. The analyses evaluated coverage, age-group compliance, and cancer detected., Findings: After 30 months, the coverage projection was greater than 80%. The age compliance for the HPV test was 99.25%, compared to 78.0% in the cytology program. The HPV test program showed 86.8% negative tests and 6.3% colposcopy referrals, with 78% colposcopies performed. The HPV testing program detected 21 women with cervical cancer with a mean age of 39.6 years, and 67% of cancers were early-stage compared to 12 cervical cancer cases detected by cytological screening (p=0.0284) with a mean age of 49.3 years (p=0.0158), and one case of early-stage (p=0.0014)., Interpretation: Organizing cervical cancer screening using DNA-HPV testing demonstrated high coverage and age compliance in a real-life scenario, and it had an immediate impact on cervical cancer detection at an early-stage., Funding: University of Campinas, Indaiatuba City, and Roche Diagnostics., Competing Interests: The authors declare that they have no competing interests., (© 2021 The Author(s).)

- Abstract
Objectives: To analyze the magnitude of changes in the incidence and mortality from cervical cancer (CC) and breast cancer (BC) in Campinas, São Paulo State, between the five-year periods of 1991-1995 and 2010-2014., Methods: data on cancer were obtained from the Campinas Population-Based Cancer Registry and data on deaths from the Mortality Information System of the Computing Department of the Unified Health System. Age-standardized incidence and mortality rates were calculated by the direct method, with the respective 95% confidence intervals. The magnitude of the changes was measured by the rate ratio (rate ratio; 95%CI)., Results: among the periods studied, there was a threefold increase in the detection rate of in situ CC (3.03; 95%CI: 2.64-3.47) and fivefold increase for in situ BC (5.23; 95%CI: 4.98-5.50). The proportion of cases of in situ BC in relation to the total number of cases of BC increased from 3.31% to 11.05%. The incidence rate of invasive CC decreased by 57% (0.43; 95%CI: 0.40-0.47), and the incidence rate of invasive BC increased by 40% (1.40; 95%CI: 1.33-1.47). The mortality rate of the CC decreased by 58% (0.42; 95%CI: 0.32-0.56), and that of BC by 15% (0.85; 95%CI: 0.82-0.89)., Conclusion: the incidence of in situ carcinomas of CC and BC increased in almost two decades. The rate of invasive carcinoma of CC decreased, and that of BC increased. Mortality from both cancers decreased. Observing these changes is useful for assessing the impact of the actions carried out in the period and for planning future actions.

- Abstract
Purpose: To compare the frequency of an ASCUS Pap Smear result in pregnant and non-pregnant women, stratified by age group., Methods: We analyzed the results of 1,336,180 cytopathologyc exams of Pap smears performed between 2000 and 2009 (ten years) with the purpose of screening for cervical carcinoma. Comparisons were made between pregnant and non-pregnant women, and the sample was stratified into three age groups (20-24, 25-29 and 30-34 years). The χ2 test was used and the magnitude of association was determined by the by Odds Ratio (OR) with the 95% confidence interval (95%CI)., Results: A Total of 447,489 samples were excluded on the basis of the criteria adopted, for a total final sample of 37,137 pregnant women and 851,554 non-pregnant women. An ASCUS result was detected in 1.2% of cases, with a significant difference between pregnant and non-pregnant women in the age groups of 20-24 years (OR=0.85; 95%CI 0.75-0.97) and 25-29 years (OR=0.78; 95%CI 0.63-0.96). There was no difference in the group between 30-34 years (OR=0.76; 95%CI 0.57-1.03)., Conclusions: This study suggested that non-pregnant women have a higher frequency of ASCUS, most evident in the age group of 20 to 29 years. The collection of cervical cancer screening should not be a compulsory part of the prenatal routine.

- Abstract
Uterine cervical cancer mortality has not been declining. The territorial distribution and registration of families in Brazil's Family Health Strategy help identify women that have performed a Pap smear or that have not had one for more than three years. This study analyzed whether cervical cancer screening in Amparo, São Paulo State, Brazil, made progress in complying with the prevailing guidelines during the seven years of experience with the Strategy. The annual examination rate remained high, with a slight trend towards greater intervals between follow-up tests. Distribution of tests tended to increase in the 40-59-year age bracket and decrease in the over-60 age group, while annual coverage tended to decrease. The proportions of excess tests varied from 61.2% to 65.5%. Concluding, the upgrading of cervical cancer screening was slight, and did not change the opportunistic pattern of follow-up tests. Considering that community health agents can act to increase the coverage of these measures, it is essential to train them for this work.
