“…In this study, when assessing the time elapsed between the last mammography before the diagnosis of breast cancer and the diagnosis, it was observed that 49.5% (49/99) of the participants had done the examination less than 12 months ago; in 17.2% (17/99) of the cases, between 12 and 24 months; and in 33.3% (33/99), for more than 24 months. Similar data were found in the study conducted by Ahn et al, in which, among the 1,125 analyzed patients, 73% had been screened 24 months before diagnosis and 27% had been screened over 25 months ago 6 .…”

“…When assessing the adopted treatment and its relationship with mammography screening, the present study showed that patients who underwent mammography biannually or more frequently had outcomes of surgical interventions and chemotherapy treatment similar to those of women who underwent mammography without defined frequency or who had never done it. This result is also evidenced by the study of Ahn et al, who demonstrated less invasive therapeutic interventions in patients who underwent mammography with a biennial frequency 6 , although in the present study the absolute majority of patients had undergone less invasive treatments.…”

“…Consequently, there is a decrease in the need for extensive medical interventions and surgical approaches. Therefore, when making a decision regarding the use of mammography, one should not only take into account the survival advantage, but also the advantage of avoiding highly aggressive treatments 6 . That is why mammography screening is believed to save lives and has been the main pillar of screening for breast cancer 7 .…”

Impact of mammography screening on the treatment of women diagnosed with breast cancer

Objective: To evaluate the influence of mammographic screening on the treatment of women with previous diagnosis of breast cancer. Method: Cross-sectional, descriptive, observational study, with primary and secondary data collection and quantitative approach. It was performed in a high complexity hospital in the South region of Santa Catarina, Brazil, where patients with previous history of breast cancer were evaluated during the period from 2012 to 2017, and who were undergoing oncological follow-up at the same hospital. The variables were expressed as frequency and percentage. Inferential statistical analyses were performed with a significance level of alpha = 0.05 and, therefore, 95% confidence interval. Therefore, the confidence interval was 95%. Associations between variables were investigated using the Pearson’s χ² and the likelihood ratio tests. Results: Among the 99 analyzed patients, 58.6% annually performed the examination and 49.5% had elapsed less than 12 months between the last performed mammogram and the diagnosis. There was a higher frequency of stage I disease, corroborating the results that 74.7% of patients underwent breastconserving surgeries and 68.7% underwent sentinel lymph node biopsy, rather than extensive surgeries. Regarding the treatment of choice, patients with annual or biennial mammographic frequency had similar surgical and chemotherapeutic outcomes in relation to patients who had a mammogram without defined frequency or who had never undergone it. Conclusion: Patients who underwent mammography on an annual frequency and those whose time between the last mammogram and the diagnosis of cancer was less than 12 months had tumors of lesser extent at diagnosis; however, it did not influence the type of treatment chosen.

“…Two small-scale US studies of breast cancer patients also reported participation in screening to be associated with more conservative treatment, including less axillary node dissection (Ahn et al, 2018;Elder et al, 2018). Also, a recent national cohort study from France reported women aged 50-74 years who were screened by mammography within 2 years before diagnosis were more likely to have breast-conserving surgery and less chemotherapy (Lefeuvre et al, 2019).…”

Objective: To examine the screening-treatment-mortality pathway among women with invasive breast cancer in 2006-2014 using linked data.Methods: BreastScreen histories of South Australian women diagnosed with breast cancer (n = 8453) were investigated. Treatments recorded within 12 months from diagnosis were obtained from linked registry and administrative data. Associations of screening history with treatment were investigated using logistic regression and with cancer mortality outcomes using competing risk analyses, adjusting for sociodemographic, cancer and comorbidity characteristics. Results and conclusion:For screening ages of 50-69 years, 70% had participated in BreastScreen SA ≤ 5 years and 53% ≤ 2 years of diagnosis. Five-year disease-specific survival post-diagnosis was 90%. Compared with those not screened ≤5 years, women screened ≤2 years had higher odds, adjusted for socio-demographic, cancer and comorbidity characteristics, and diagnostic period, of breast-conserving surgery (aOR 2.5, 95% CI 1.9-3.2) and radiotherapy (aOR 1.2, 95% CI 1.1-1.3). These women had a lower unadjusted risk of post-diagnostic cancer mortality (SHR 0.33, 95% CI 0.27-0.41), partly mediated by stage (aSHR 0.65, 95% CI 0.51-0.81), and less breast surgery (aSHR 0.78, 95% CI 0.62-0.99). Screening ≤2 years and conserving surgery

“…Early diagnosis of breast cancer is key to reduce mortality. 2 Breast imaging is an ever-growing sub-specialty of radiology, both in South Africa and worldwide. The goal is to detect cancer changes as early as possible and to be able to accurately differentiate cancer from non-malignant breast pathology.…”

Impact of Screening Mammography on Treatment in Women Diagnosed with Breast Cancer

Abstract: Screening mammography is associated with decreased stage at diagnosis and receipt of less-extensive treatment. This was evident in all groups, including the 40-49 years age group, where controversy exists on whether screening is even necessary.
