RESUMO

Post-pregnancy breast cancer often carries a poor prognosis, posing a major clinical challenge. The increasing trend of later-life pregnancies exacerbates this risk, highlighting the need for effective chemoprevention strategies. Current options, limited to selective estrogen receptor modulators, aromatase inhibitors, or surgical procedures, offer limited efficacy and considerable side effects. Here, we report that cabergoline, a dopaminergic agonist, reduces the risk of breast cancer post-pregnancy in a Brca1/P53-deficient mouse model, with implications for human breast cancer prevention. We show that a single dose of cabergoline administered post-pregnancy significantly delayed the onset and reduced the incidence of breast cancer in Brca1/P53-deficient mice. Histological analysis revealed a notable acceleration in post-lactational involution over the short term, characterized by increased apoptosis and altered gene expression related to ion transport. Over the long term, histological changes in the mammary gland included a reduction in the ductal component, decreased epithelial proliferation, and a lower presence of recombinant Brca1/P53 target cells, which are precursors of tumors. These changes serve as indicators of reduced breast cancer susceptibility. Additionally, RNA sequencing identified gene expression alterations associated with decreased proliferation and mammary gland branching. Our findings highlight a mechanism wherein cabergoline enhances the protective effect of pregnancy against breast cancer by potentiating postlactational involution. Notably, a retrospective cohort study in women demonstrated a markedly lower incidence of post-pregnancy breast cancer in those treated with cabergoline compared to a control group. Our work underscores the importance of enhancing postlactational involution as a strategy for breast cancer prevention, and identifies cabergoline as a promising, low-risk option in breast cancer chemoprevention. This strategy has the potential to revolutionize breast cancer prevention approaches, particularly for women at increased risk due to genetic factors or delayed childbirth, and has wider implications beyond hereditary breast cancer cases.

RESUMO

OBJECTIVE: Diagnosis of cancer is challenging in primary care due to the low incidence of cancer cases in primary care practice. A prolonged diagnostic interval may be due to doctor, patient or system factors, or may be due to the characteristics of the cancer itself. The objective of this study was to learn from Primary Care Physicians' (PCP) experiences of incidents when they had failed to think of, or act on, a cancer diagnosis. DESIGN: A qualitative, online survey eliciting PCP narratives. Thematic analysis was used to analyse the data. SETTING AND SUBJECTS: A primary care study, with narratives from 159 PCPs in 23 European countries. MAIN OUTCOME MEASURES: PCPs' narratives on the question 'If you saw this patient with cancer presenting in the same way today, what would you do differently? RESULTS: The main themes identified were: thinking broadly; improvement in communication and clinical management; use of other available resources and 'I wouldn't do anything differently'. CONCLUSION (IMPLICATIONS): To achieve more timely cancer diagnosis, PCPs need to provide a long-term, holistic and active approach with effective communication, and to ensure shared decision-making, follow-up and continuing re-assessment of the patients' clinical conditions.


Diagnosing cancer in primary care is challenging due to the low incidence of cancer in practice and the multiple confounding factors that are involved in the diagnostic process.The need to think broadly, make improvements in communication and clinical management, and use other available resources were the main themes from Primary Care Physicians' (PCPs') narratives about their learning experiences from missed or late cancer diagnoses.A long-term, holistic and active approach with effective communication, follow-up and continuing re-assessment of the patients' clinical conditions was another theme for making improvements.Some PCPs, on reflection, would not have done anything differently.

RESUMO

BACKGROUND: While primary care physicians (PCPs) play a key role in cancer detection, they can find cancer diagnosis challenging, and some patients have considerable delays between presentation and onward referral. AIM: To explore European PCPs' experiences and views on cases where they considered that they had been slow to think of, or act on, a possible cancer diagnosis. DESIGN & SETTING: A multicentre European qualitative study, based on an online survey with open-ended questions, asking PCPs for their narratives about cases when they had missed a diagnosis of cancer. METHOD: Using maximum variation sampling, PCPs in 23 European countries were asked to describe what happened in a case where they were slow to think of a cancer diagnosis, and for their views on why it happened. Thematic analysis was used to analyse the data. RESULTS: A total of 158 PCPs completed the questionnaire. The main themes were as follows: patients' descriptions did not suggest cancer; distracting factors reduced PCPs' cancer suspicions; patients' hesitancy delayed the diagnosis; system factors not facilitating timely diagnosis; PCPs felt that they had acted wrongly; and problems with communicating adequately. CONCLUSION: The study identified six overarching themes that need to be addressed. Doing so should reduce morbidity and mortality in the small proportion of patients who have a significant, avoidable delay in their cancer diagnosis. The 'Swiss cheese' model of accident causation showed how the themes related to each other.

RESUMO

Objetivo: Identificar las oportunidades perdidas en el diagnóstico del cáncer de ovario (CO) en el sistema sanitario público de Catalunya mediante el análisis de la visión de los profesionales sobre el relato de las experiencias de las pacientes con CO. Diseño: Estudio cualitativo exploratorio-descriptivo, con dos grupos focales. Emplazamiento: Atención primaria, noviembre de 2017. Participantes: Treinta y cuatro profesionales en base a un muestreo teórico: 21médicos de familia, 8profesionales de centros de salud sexual y reproductiva y 5ginecólogos de hospital. Métodos: Los participantes debatieron sobre diferentes itinerarios de procesos diagnósticos de mujeres con CO mediante la exposición de tres flujogramas elaborados a partir de los relatos obtenidos en entrevistas a pacientes. Se realizó un análisis de contenido temático. Resultados: Se identificaron tres temas con diversos subtemas: a)falta de sospecha diagnóstica (desconocimiento de los síntomas, obviar la anamnesis y la exploración física, fragmentación de la atención y sesgos y prejuicios); b)dificultades para activar el proceso diagnóstico (acceso limitado a pruebas, accesibilidad desigual a ginecología y falta de seguimiento), y c)ausencia de circuitos rápidos preestablecidos. Conclusiones: Los resultados ofrecen una visión de las dificultades del diagnóstico precoz del CO en nuestro ámbito. Creemos que su identificación permitirá la elaboración de estrategias para mejorar la precisión diagnóstica y la calidad de la atención en las mujeres con CO en nuestro medio.(AU)


Objective: To identify missed opportunities in the diagnosis of ovarian cancer (OC) in the public health system of Catalonia, through the analysis of the perceptions of health professionals on the stories's experiences of OC patients. Design: Qualitative exploratory-descriptive study, with two focus groups. Setting: Primary Care, November 2017. Participants: Thirty-four professionals based on theoretical sampling: 21 family doctors, 8 professionals from sexual and reproductive health centres and 5 hospital gynaecologists. Methods: Participants discussed the different diagnostic pathways for women with OC through the presentation of flowcharts which were developed with three storie's and experiences of OC patients. Results: Three themes with various sub-themes were identified as follow: a)lack of cancer diagnostic suspicion (lack of knowledge of symptoms of OC, anamnesis and physical examination overlooked, fragmentation of patient's care and bias and prejudice); b)difficulties in activating the diagnostic process (limited access to tests, unequal accessibility to gynaecology and lack of follow-up); and c)absence of fast-track referral system.Conclusions: The results offer insight into the difficulties of early diagnosis of OC in our setting. We believe that their identification will allow the development of strategies to improve diagnostic accuracy and quality of care for women with OC in our setting.(AU)

RESUMO

BACKGROUND: During the COVID-19 pandemic, the incidence of chronic disease had drastically been reduced due to health care interruptions. The aim of this study is to analyse cancer diagnosis during the last 2 years of the COVID-19 pandemic. METHODS: Time-series study of cancer diagnoses recorded in primary care settings, using data from the primary care electronic health records from January 2014 to December 2021. We obtained the expected monthly rate per 100,000 inhabitants using a time regression adjusted by trend and seasonality. We additionally compared rates of cancer diagnoses in 2019 with those of 2020 and 2021 using the t-test. We performed the analysis globally, by sex and by type of cancer. RESULTS: In 2020, the rate of cancer diagnoses had reduced by -21% compared to 2019 (P < 0.05). Greater reductions were observed during the lockdown in early 2020 (>40%) and with some types of cancers, especially prostate and skin cancers (-29.6% and -26.9%, respectively, P < 0.05). Lung cancers presented statistically non-significant reductions in both years. Cancer diagnosis returned to expected around March 2021, and the rate in 2021 was similar to that of 2019 (overall difference of 0.21%, P = 0.967). However, an 11% reduction was still found when comparing the pandemic months of 2020-2021 with pre-pandemic months. CONCLUSIONS: Although primary care cancer diagnoses in 2021 have returned to pre-pandemic levels, missing diagnoses during the last 2 years have not been fully recovered.

RESUMO

BACKGROUND: Early detection of symptoms and prompt diagnosis of ovarian cancer are considered important avenues for improving patient experiences and outcomes. METHODS: This qualitative study used a phenomenological approach to perform patient interviews, collecting individual accounts of the prediagnostic phase in women diagnosed and treated for ovarian cancer in 2016-2017. Purposive sampling was used to obtain a diverse sample of 24 participants, while thematic content analysis was used to extract themes and subthemes from interview data. RESULTS: Three themes and nine subthemes were identified. The first theme was women's delay in recognizing symptoms and seeking care, with subthemes on the lack of knowledge about early signs of ovarian cancer, gender-related barriers and false reassurance from negative test results. A second theme was missed opportunities during healthcare encounters, due to misattribution of women's symptoms by their physicians, underestimation of symptom severity and need for mediation and inadequate tests and/or false negative results. Finally, interviews highlighted the use of resources and alternative healthcare pathways, including complementary/alternative medicines, access to private health care and women's capacity for action and decision-making (agency) about their health. CONCLUSION: Delayed diagnosis of ovarian cancer is rooted in both individual factors (lack of health literacy, reluctance to seek care) and systemic issues (missed opportunities in healthcare encounters, access to timely specialist care). Further research is needed to investigate the extent to which traditional gender roles and socioeconomic inequalities condition women's ability to manage their own health and to interact with health professionals and the health system. PATIENT AND PUBLIC CONTRIBUTION: In addition to the patient participation during the interviews, one author was a representative of a patient association.

RESUMO

BACKGROUND: Some symptoms are recognised as red flags for cancer, causing the General Practitioner (GP) to refer the patient for investigation without delay. However, many early symptoms of cancer are vague and unspecific, and in these cases, a delay in referral risks a diagnosis of cancer that is too late. Empowering GPs in their management of patients that may have cancer is likely to lead to more timely cancer diagnoses. AIM: To identify the factors that affect European GPs' empowerment in making an early diagnosis of cancer. METHODS: This was a Delphi study involving GPs in 20 European countries. We presented GPs with 52 statements representing factors that could empower GPs to increase the number of early cancer diagnoses. Over three Delphi rounds, we asked GPs to indicate the clinical relevance of each statement on a Likert scale.The final list of statements indicated those that were considered by consensus to be the most relevant. RESULTS: In total, 53 GPs from 20 European countries completed the Delphi process, out of the 68 GPs who completed round one. Twelve statements satisfied the pre-defined criteria for relevance. Five of the statements related to screening and four to the primary/secondary care interface. The other selected statements concerned information technology (IT) and GPs' working conditions. Statements relating to training, skills and working efficiency were not considered priority areas. CONCLUSION: GPs consider that system factors relating to screening, the primary-secondary care interface, IT and their working conditions are key to enhancing their empowerment in patients that could have cancer. These findings provide the basis for seeking actions and policies that will support GPs in their efforts to achieve timely cancer diagnosis.

RESUMO

Cancer is a major cause of morbidity and mortality. Tobacco use, unhealthy diet, and physical inactivity are some of the lifestyle risk factors that have led to an increase in cancer. This article updates the evidence and includes recommendations for prevention strategies for each of the cancers with the highest incidence. These are based on the reduction of risk factors (primary prevention) and early diagnosis of cancer through screening and early detection of signs and symptoms, in medium-risk and high-risk populations. This update of the 2022 PAPPS has taken into account the vision of the National Health System Cancer Strategy, an update approved by the Interterritorial Council of the National Health System on January 2021 and the European Strategy (Europe's Beating Cancer Plan) presented on 4 February 2021.

RESUMO

OBJECTIVE: To assess the impact of prehospital factors (diagnostic pathways, first presentation to healthcare services, intervals, participation in primary care) on 1-year and 5-year survival in people with epithelial ovarian cancer (EOC). DESIGN: Retrospective quasi-population-based cohort study. SETTING: Catalan Integrated Public Healthcare System. PARTICIPANTS: People with EOC who underwent surgery with a curative intent in public Catalan hospitals between 1 January 2013 and 31 December 2014. OUTCOME MEASURES: Data from primary and secondary care clinical histories and care processes in the 18 months leading up to confirmation (signs and symptoms at presentation, diagnosis pathways, referrals, diagnosis interval) of the EOC diagnosis (stage, histology type, treatment). Diagnostic process intervals were based on the Aarhus statement. 1-year and 5-year survival analysis was undertaken. RESULTS: Of the 513 patients included in the cohort, 67.2% initially consulted their family physician, while 36.4% were diagnosed through emergency services. In the Cox models, survival was influenced by advanced stage at 1 year (HR 3.84, 95% CI 1.23 to 12.02) and 5 years (HR 5.36, 95% CI 3.07 to 9.36), as was the type of treatment received, although this association was attenuated over follow-up. Age became significant at 5 years of follow-up. After adjusting for age, adjusted morbidity groups, stage at diagnosis and treatment, 5-year survival was better in patients presenting with gynaecological bleeding (HR 0.35, 95% CI 0.16 to 0.79). Survival was not associated with a starting point involving primary care (HR 1.39, 95% CI 0.93 to 2.09), diagnostic pathways involving referral to elective gynaecological care from non-general practitioners (HR 0.80, 95% CI 0.51 to 1.26), or self-presentation to emergency services (HR 0.82, 95% CI 0.52 to 1.31). CONCLUSIONS: Survival in EOC is not associated with diagnostic pathways or prehospital healthcare, but it is influenced by stage at diagnosis, administration of primary cytoreduction plus chemotherapy and patient age.

RESUMO

OBJECTIVES: To assess the impact of relaxing the state of alarm restrictions on SARS-CoV-2 infections at 14 days among people attending reopened nightclub venues. DESIGN: Matched cohort study with a paired control group (1:5 ratio). SETTING: Five small nightclubs with indoor areas and outdoor terraces, in a nightlife-restricted area in Sitges, Spain, on 20 May 2021. Wearing masks was mandatory, drinking was allowed and social distance was not required. PARTICIPANTS: Volunteers were selected through a convenience sampling. To attend the event, participants were required to be older than 17 years, with a negative rapid antigen diagnostic test (Ag-RDT) on the same afternoon, without a positive reverse-transcription PCR (RT-PCR) or Ag-RDT and/or symptoms associated with COVID-19 in the previous 7 days, to not having knowingly been in close contact with someone infected in the previous 10 days and to not have knowingly had close contact with someone with a suspicion of COVID-19 in the previous 48 hours. A control group was paired by exact age, gender, residence municipality, socioeconomic index, previous SARS-CoV-2-confirmed infection and vaccination status, in a 1:5 ratio, from the primary care electronic health records. PRIMARY OUTCOME: Evidence of infection at electronic health records by SARS-CoV-2 at 14-day follow-up. RESULTS: Among the 391 participants (median age 37 years; 44% (n=173) women), no positive SARS-CoV-2 cases were detected at 14 days, resulting in a cumulative incidence estimation of 0 (95% CI 0 to 943) per 100 000 inhabitants. In the control group, two cases with RT-PCR test were identified, resulting in a cumulative incidence of 102.30 (12.4 to 369) per 100 000 inhabitants. CONCLUSIONS: Nightlife attendance under controlled conditions and with a requirement for a negative Ag-RDT was not associated with increased transmissibility of SARS-CoV-2 in a pandemic context of low infection rates. In such circumstances, secure opening of the nightlife sector was possible, under reduced capacity and controlled access by Ag-RDT, and environments where compliance with sanitary measures are maintainable.

RESUMO

El cáncer de mama es la primera causa de muerte en el mundo entre las mujeres. El Sistema Nacional de Salud (SNS) introdujo el cribado poblacional de cáncer de mama en 1990. Como en la mayoría de los programas europeos, el riesgo se identifica con base en la edad y se ofrece una mamografía cada dos años a mujeres de 50 a 69 años. La evidencia científica está avanzando hacia un cribado personalizado, basado en el riesgo individual. En este artículo se presentan los ensayos clínicos que evaluarán la eficacia del cribado personalizado y algunos estudios realizados en nuestro entorno sobre el efecto de informar a las mujeres de los beneficios y efectos adversos del cribado o la aceptabilidad y viabilidad de ofrecer cribado personalizado, que incluya la toma de decisiones compartidas. El Programa de Actividades Preventivas y Promoción de la Salud puede ayudar a transformar el cribado en nuestro SNS.(AU)

RESUMO

OBJECTIVE: Cancer care has been disrupted by the response of health systems to the COVID-19 pandemic, especially during lockdowns. The objective of our study is to evaluate the impact of the pandemic on the incidence of cancer diagnoses in primary care. DESIGN: Time-series study of malignant neoplasms and diagnostic procedures, using data from the primary care electronic health records from January 2014 to September 2020. SETTING: Primary care, Catalonia, Spain. PARTICIPANTS: People older than 14 years and assigned in one of the primary care practices of the Catalan Institute of Health with a new diagnosis of malignant neoplasm. MAIN OUTCOME MEASURES: We obtained the monthly expected incidence of malignant neoplasms using a temporary regression, where the response variable was the incidence of cancer from 2014 to 2018 and the adjustment variables were the trend and seasonality of the time series. Excess or lack of malignant neoplasms was defined as the number of observed minus expected cases, globally and stratified by sex, age, type of cancer and socioeconomic status. RESULTS: Between March and September 2020 we observed 8766 (95% CI 4135 to 13 397) fewer malignant neoplasm diagnoses, representing a reduction of 34% (95% CI 19.5% to 44.1%) compared with the expected. This underdiagnosis was greater in individuals aged older than 64 years, men and in some types of cancers (skin, colorectal, prostate). Although the reduction was predominantly focused during the lockdown, expected figures have not yet been reached (40.5% reduction during the lockdown and 24.3% reduction after that). CONCLUSIONS: Reduction in cancer incidence has been observed during and after the lockdown. Urgent policy interventions are necessary to mitigate the indirect effects of the COVID-19 pandemic and related control measures on other diseases and some strategies must be designed in order to reduce the underdiagnosis of cancer.

RESUMO

OBJECTIVES: Cancer survival rates vary widely between European countries, with differences in timeliness of diagnosis thought to be one key reason. There is little evidence on the way in which different healthcare systems influence primary care practitioners' (PCPs) referral decisions in patients who could have cancer.This study aimed to explore PCPs' diagnostic actions (whether or not they perform a key diagnostic test and/or refer to a specialist) in patients with symptoms that could be due to cancer and how they vary across European countries. DESIGN: A primary care survey. PCPs were given vignettes describing patients with symptoms that could indicate cancer and asked how they would manage these patients. The likelihood of taking immediate diagnostic action (a diagnostic test and/or referral) in the different participating countries was analysed. Comparisons between the likelihood of taking immediate diagnostic action and physician characteristics were calculated. SETTING: Centres in 20 European countries with widely varying cancer survival rates. PARTICIPANTS: A total of 2086 PCPs answered the survey question, with a median of 72 PCPs per country. RESULTS: PCPs' likelihood of immediate diagnostic action at the first consultation varied from 50% to 82% between countries. PCPs who were more experienced were more likely to take immediate diagnostic action than their peers. CONCLUSION: When given vignettes of patients with a low but significant possibility of cancer, more than half of PCPs across Europe would take diagnostic action, most often by ordering diagnostic tests. However, there are substantial between-country variations.

RESUMO

Cancer is a major cause of morbidity and mortality. Tobacco use, unhealthy diet, and physical inactivity are some of the lifestyle risk factors that have led to an increase in cancer. This article updates the evidence, and includes recommendations for prevention strategies for each of the cancers with the highest incidence. These are based on the reduction of risk factors (primary prevention) and early diagnosis of cancer through screening and early detection of signs and symptoms, in medium-risk and high-risk populations.

RESUMO

BACKGROUND: National European cancer survival rates vary widely. Prolonged diagnostic intervals are thought to be a key factor in explaining these variations. Primary care practitioners (PCPs) frequently play a crucial role during initial cancer diagnosis; their knowledge could be used to improve the planning of more effective approaches to earlier cancer diagnosis. OBJECTIVES: This study sought the views of PCPs from across Europe on how they thought the timeliness of cancer diagnosis could be improved. DESIGN: In an online survey, a final open-ended question asked PCPs how they thought the speed of diagnosis of cancer in primary care could be improved. Thematic analysis was used to analyse the data. SETTING: A primary care study, with participating centres in 20 European countries. PARTICIPANTS: A total of 1352 PCPs answered the final survey question, with a median of 48 per country. RESULTS: The main themes identified were: patient-related factors, including health education; care provider-related factors, including continuing medical education; improving communication and interprofessional partnership, particularly between primary and secondary care; factors relating to health system organisation and policies, including improving access to healthcare; easier primary care access to diagnostic tests; and use of information technology. Re-allocation of funding to support timely diagnosis was seen as an issue affecting all of these. CONCLUSIONS: To achieve more timely cancer diagnosis, health systems need to facilitate earlier patient presentation through education and better access to care, have well-educated clinicians with good access to investigations and better information technology, and adequate primary care cancer diagnostic pathway funding.

RESUMO

La evidencia disponible para estratificar el riesgo de presentar un cáncer colorrectal metacrónico tras la extirpación de pólipos colorrectales y determinar los intervalos de vigilancia es limitada y se basa en estudios observacionales. No obstante, a la espera de nuevas evidencias, es necesario unificar los criterios del seguimiento endoscópico en nuestro medio. Por ello, desde las principales sociedades científicas involucradas en el manejo de estos pacientes, como son la Asociación Española de Gastroenterología, la Sociedad Española de Medicina Familiar y Comunitaria, la Sociedad Española de Endoscopia Digestiva y el Grupo de Cribado de Cáncer Colorrectal de la Sociedad Española de Epidemiología, se ha creado este documento de consenso, que se encuentra incluido en el capítulo 10 de la «Guía de Práctica Clínica de Diagnóstico y Prevención del Cáncer Colorrectal. Actualización 2018». A continuación, se presentarán importantes novedades respecto a la edición previa publicada en 2009. En primer lugar, se establecen situaciones que requieren y no requieren vigilancia endoscópica y se elimina la necesidad de realizar seguimiento en individuos que no presentan un riesgo especial de cáncer de colon metacrono. En segundo lugar, se establecen recomendaciones de vigilancia endoscópica en individuos con pólipos serrados. Finalmente, a diferencia de la edición anterior, se dan recomendaciones de vigilancia endoscópica en individuos intervenidos por cáncer colorrectal. Paralelamente, supone un avance sobre la guía europea de calidad en el cribado del cáncer colorrectal, ya que elimina la división entre grupo de riesgo medio y grupo de riesgo alto, lo que supone la eliminación de una proporción considerable de colonoscopias de vigilancia precoz. Finalmente, se dan recomendaciones claras sobre la ausencia de necesidad de seguimiento en el grupo de riesgo bajo, para el que la guía europea mantenía cierta ambigüedad


There is limited scientific evidence available to stratify the risk of developing metachronous colorectal cancer after resection of colonic polyps and to determine surveillance intervals and is mostly based on observational studies. However, while awaiting further evidence, the criteria of endoscopic follow-up needs to be unified in our setting. Therefore, the Spanish Association of Gastroenterology, the Spanish Society of Family and Community Medicine, the Spanish Society of Digestive Endoscopy, and the Colorectal Cancer Screening Group of the Spanish Society of Epidemiology, have written this consensus document, which is included in chapter 10 of the "Clinical Practice Guideline for Diagnosis and Prevention of Colorectal Cancer. 2018 Update". Important developments will also be presented as regards the previous edition published in 2009. First of all, situations that require and do not require endoscopic surveillance are established, and the need of endoscopic surveillance of individuals who do not present a special risk of metachronous colon cancer is eliminated. Secondly, endoscopic surveillance recommendations are established in individuals with serrated polyps. Finally, unlike the previous edition, endoscopic surveillance recommendations are given in patients operated on for colorectal cancer. At the same time, it represents an advance on the European guideline for quality assurance in colorectal cancer screening, since it eliminates the division between intermediate risk group and high risk group, which means the elimination of a considerable proportion of colonoscopies of early surveillance. Finally, clear recommendations are given on the absence of need for follow-up in the low risk group, for which the European guidelines maintained some ambiguity
