“…O aumento da detecção do CCU in situ em Campinas provavelmente se deve à estratégia de rastreamento implantada no município desde a década de 1960 22 . Já a redução da incidência do CCU invasivo pode ser atribuída ao aumento do diagnóstico do CCU in situ, à disponibilidade de rede de atenção para tratamento das lesões precursoras e ao seguimento das pacientes.…”

OBJETIVOS Analisar a magnitude das mudanças na incidência e mortalidade por câncer do colo do útero (CCU) e câncer de mama (CM) em Campinas (SP) entre os quinquênios 1991–1995 e 2010–2014. MÉTODOS Os dados sobre câncer foram obtidos do Registro de Câncer de Base Populacional de Campinas e os dados sobre óbitos do Sistema de Informação de Mortalidade do Departamento de Informática do Sistema Único de Saúde. Foram calculadas taxas de incidência e de mortalidade padronizadas por idade pelo método direto, com os respectivos intervalos de confiança de 95%. Mensurou-se a magnitude das mudanças por meio da razão de taxas (RT). RESULTADOS Entre os períodos estudados, houve aumento de três vezes na taxa de detecção do CCU in situ (RT = 3,03; IC95% 2,64–3,47) e de 5 vezes para o CM in situ (RT = 5,23; IC95% 4,98–5,50). A proporção de casos de CM in situ em relação ao total de casos de CM aumentou de 3,31% para 11,05%. A taxa de incidência do CCU invasivo declinou em 57% (RT = 0,43; IC95% 0,40–0,47), e a do CM invasivo aumentou em 40% (RT = 1,40; IC95% 1,33–1,47). A taxa de mortalidade do CCU caiu em 58% (RT = 0,42; IC95% 0,32–0,56), e a do CM em 15% (RT = 0,85; IC95% 0,82–0,89). CONCLUSÃO A incidência de carcinomas in situ de CCU e CM aumentou nessas quase duas décadas. A taxa de carcinoma invasivo do CCU diminuiu, e a do CM aumentou. A mortalidade pelos dois cânceres foi reduzida. Observar essas alterações é útil para avaliar o impacto das ações realizadas no período e planejar ações futuras.

“…False-negatives may also occur as a result of actinic changes, as well as difficulty in collecting adequate samples because of changes in the anatomy of the cervix and vaginal canal, especially with brachytherapy, leading to inadequate treatment. It is a consensus among professionals who perform microscopic analyzes (cytopathologists, cytologists and cytotechnicians) 42 that it is often difficult to differentiate actinic alterations in normal cells from cellular atypia in recurrent tumors.…”

Summary Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine. Based on the difficulties of cytopathologic evaluation for the follow-up of patients treated with radiotherapy for cervical cancer, our objective was to describe the actinic cytopathic effects. Our paper was based on a structured review including the period from June 2015 to April 2016, aiming at an exploratory-descriptive study. Bibliographic investigations were carried out through selection and analysis of articles, list of authors and keywords, selection of new articles focused on the analysis of bibliographic references to previously selected documents, as well as textbooks of recognized merit. The most incident actinic cytopathological alterations as described in the literature are: cellular gigantism, nuclear and cytoplasmic vacuolization, dyskeratosis, bi- and multinucleated (B/M) cells, macro and multiple nucleoli, anisokaryosis, anisonucleolosis and nuclear pyknosis. To date, a protocol has not been established that can precisely differentiate the morphological characteristics between benign cells with actinic effects from recurrent malignant cells on post-radiotherapy smears.

“…As well as formulating campaigns in diverse areas in partnership with other institutions, they worked to train technical staff to implement these initiatives. Their cytotechnical training school, created in 1968, as well as pioneering, served as a model for training these professionals in Brazil (Teixeira, Porto, Souza, 2012;Temperini, 2012).…”

This paper discusses the knowledge and medical practices relating to cervical cancer in Brazil. It analyses the growing medical interest in the disease at the beginning of the twentieth century, the development of prevention techniques in the 1940s, and the emergence of screening programs in the 1960s. It argues that the development of knowledge on cervical cancer was related simultaneously to a number of factors: transformations in medical knowledge, the development of the idea that the disease should be treated as a public health problem, the increased concerns with women's health, and major changes to the Brazilian healthcare system. The article concludes by identifying a number of issues that are still proving to be obstacles to control of the disease.
