Breast cancer screening

A qualitative study to determine Kuwaiti Women's knowledge of breast cancer and barriers deterring attendance at mammography screening

INTRODUCTION

Although a Mammography Screening Service (MSS) has been established in Kuwait since 2014, the attendance rate for eligible women is only 4.2% in comparison to 72.1% attendance in the United Kingdom (UK) mammography screening service. The aim of this study was to determine Kuwaiti women's knowledge of breast cancer (BC), their attitudes toward BCS and the reasons for not attending Mammography Screening (MS).

METHODS

A pragmatic qualitative methodology was used which included the use of two focus groups conducted at two women only social organisations in Kuwait with a total of 23 women. One focus group was conducted at a social and cultural organisation; the second focus group took place at a social organisation whose primary role is the improvement of literacy though the use of religious scripture. Thematic analysis was applied to the recorded verbal transcripts from each focus group.

RESULTS

Thematic analysis revealed four major themes, accompanied by a series of subthemes (1) knowledge and awareness of BC health, (2) knowledge of MS (3) personal factors, (4) medical provision and social environment.

CONCLUSION

Findings suggest that participant's knowledge of BC and the decision to attend MS is influenced by a series of factors both personal and external. An increase in the awareness of BC, MS and the process of accessing MSS will enhance the uptake of MS among Kuwaiti women. Furthermore, doctors and health care providers will need to play a significant role in encouraging women to self-refer.

European transnational ecological deprivation index and participation in population-based breast cancer screening programmes in France

BACKGROUND

We investigated factors explaining low breast cancer screening programme (BCSP) attendance taking into account a European transnational ecological Deprivation Index.

PATIENTS AND METHODS

Data of 13,565 women aged 51-74years old invited to attend an organised mammography screening session between 2010 and 2011 in thirteen French departments were randomly selected. Information on the women's participation in BCSP, their individual characteristics and the characteristics of their area of residence were recorded and analysed in a multilevel model.

RESULTS

Between 2010 and 2012, 7121 (52.5%) women of the studied population had their mammography examination after they received the invitation. Women living in the most deprived neighbourhood were less likely than those living in the most affluent neighbourhood to participate in BCSP (OR 95%CI=0.84[0.78-0.92]) as were those living in rural areas compared with those living in urban areas (OR 95%CI=0.87[0.80-0.95]). Being self-employed (p<0.0001) or living more than 15min away from an accredited screening centre (p=0.02) was also a barrier to participation in BCSP.

CONCLUSION

Despite the classless delivery of BCSP, inequalities in uptake remain. To take advantage of prevention and to avoid exacerbating disparities in cancer mortality, BCSP should be adapted to women's personal and contextual characteristics.

Breast cancer screening: review of benefits and harms, and recommendations for developing and low-income countries

Breast cancer is the most common cancer in women worldwide. The disease remains a public health concern as recent evidence indicates that the breast cancer burden has increased mainly in developing and low-income countries (DLICs). Despite the demonstrated benefits, the debate about the real benefits and harms of breast cancer screening is ongoing. Many experts believe that the benefits of screening, in terms of reduced breast cancer mortality, outweigh the harms, whereas others think the opposite. In this review, we assess the clinical utility of available screening modalities, present evidence, overdiagnosis, cost-effectiveness, and other pertinent issues. We also examine relevant data from DLICs to underscore the barriers and challenges that impede implementation of screening strategies in those populations. We also provide recommendations concerning rational preventive strategies for breast cancer control for women in DLICs.

Assessment of grating-based X-ray phase-contrast CT for differentiation of invasive ductal carcinoma and ductal carcinoma in situ in an experimental ex vivo set-up

OBJECTIVE

Limited contrast between healthy and tumour tissue is a limiting factor in mammography and CT of the breast. Phase-contrast computed tomography (PC-CT) provides improved soft-tissue contrast compared with absorption-based techniques. In this study, we assessed the technical feasibility of grating-based PC-CT imaging of the breast for characterisation of ductal carcinoma in situ (DCIS).

METHODS

Grating-based PC-CT was performed on one breast specimen containing an invasive ductal carcinoma and DCIS using monochromatic radiation of 23 keV. Phase-contrast and absorption-based images were compared qualitatively and quantitatively with histopathology in a blinded fashion.

RESULTS

Grating-based PC-CT showed improved differentiation of soft-tissue components. Circular structures of high phase-shift contrast corresponding to the walls of the dilated ductuli of the DCIS were visualised with a contrast-to-noise ratio (CNR) of 9.6 using PC-CT but were not detectable on absorption-based images (CNR = 0.27). The high phase-shift structures of the dilated ductuli were identifiable in the PC-CT volume data set allowing for 3D characterisation of DCIS.

CONCLUSIONS

Our results indicate that unlike conventional CT, grating-based PC-CT may allow the differentiation between invasive carcinoma and intraductal carcinoma and healthy breast tissue and provide 3D visualisation of DCIS.
