Malignancy risk of indeterminate mammographic calcification in symptomatic breast clinics

BackgroundTo explore the potential risk factors predicting malignancy in patients with indeterminate incidental mammographic microcalcification and to evaluate the short-term risk of developing malignancy.MethodsBetween January 2011 and December 2015, one hundred and fifty (150) consecutive patients with indeterminate mammographic microcalcifications who had undergone stereotactic biopsy were evaluated. Clinical and mammographic features were recorded and compared with histopathological biopsy results. In patients with malignancy, postsurgical findings and surgical upgrade, if any, were recorded. Linear regression analysis (SPSS V.25) was used to evaluate significant variables predicting malignancy. OR with 95% CIs was calculated for all variables. All patients were followed up for a maximum of 10 years. The mean age of the patients was 52 years (range 33–79 years).ResultsThere were a total of 55 (37%) malignant results in this study cohort. Age was an independent predictor of breast malignancy with an OR (95% CI) of 1.10 (1.03 to 1.16). Mammographic microcalcification size, pleomorphic morphology, multiple clusters and linear/segmental distribution were significantly associated with malignancy with OR (CI) of 1.03 (1.002 to 1.06), 6.06 (2.24 to 16.66), 6.35 (1.44 to 27.90) and 4.66 (1.07 to 20.19). The regional distribution of microcalcification had an OR of 3.09 (0.92 to 10.3), but this was not statistically significant. Patients with previous breast biopsies had a lower risk of breast malignancy than patients with no prior biopsy (p=0.034).ConclusionMultiple clusters, linear/segmental distribution, pleomorphic morphology, size of mammographic microcalcifications and increasing age were independent predictors of malignancy. Having a previous breast biopsy did not increase malignancy risk.

Reduction Mammoplasty: A Ten-Year Retrospective Review of the Omega Resection Pattern Technique

Reduction mammoplasty is the gold standard procedure for symptomatic breast hypertrophy and it is also used for contralateral breast symmetrisation following breast cancer surgery. We aim at introducing a new procedure, which uses an omega resection pattern to simplify the inferior pedicle breast resection technique. A retrospective review of all patients who underwent the omega resection reduction mammoplasty at the University Hospital of Basel between 2010 and 2020 was carried out. We collected patient demographics, surgical outcomes, operation time, type and frequency of complications at 12 months follow-up. Outcomes were compared with the most commonly used techniques. Additionally, we assessed if patients’ and clinical characteristics augmented/diminished the complication rate. During the study period, 67 reduction mammaplasties were performed by a senior plastic surgeon (Mage = 42.5, SDage = 15.6; MBMI = 27.28, SDBMI = 3.4; 20% smokers). The average tissue removed was 826 g (ranging from 15 to 2307 g). In 10 breasts (15%) occurred minor complications. No major complications were reported. Operation time (M = 149 min; ranging from 87 to 270 min) was significantly shorter than the inferior, superomedial, and superior pedicle techniques. Univariate Odd Ratios showed that no-smoker status, a BMI in a normal range, resection weight between 500 g to 1500 g, NTN distance < 30 cm, removal of drains one day after the operation, ASA index of 2, inpatient clinic hospitalisation, and not undergoing other concomitant surgical operations were protective factors against the risk to develop complications. The omega resection pattern technique demonstrated to be an effective, safe, and fast mammoplasty reduction procedure for bilateral macromastia and unilateral symmetrizing procedures, even for large breasts, able to be adopted as a new valid alternative to the existing ones.

Delayed help-seeking for symptomatic breast cancer: reasons for delay among participants receiving treatment at a public healthcare facility in South Africa

We explored delayed help-seeking behaviour for symptomatic breast cancer among a sample of female patients attending an outpatient breast cancer clinic at a tertiary public hospital in the Western Cape. The objective of the research was to explore the perceived personal and structural barriers to help-seeking among women with breast cancer from this low-resource setting, as this information has not been documented. Purposive sampling was used to recruit 25 breast cancer patients. Patients participated in individual interviews that were audio-recorded and transcribed. We conducted a thematic analysis using both inductive and deductive coding. Participants’ limited knowledge of breast cancer, negative views of the healthcare system, and challenging life experiences, such as marital discord, perceived lack of support, and caring for sick loved ones, contributed to their help-seeking delays. We used a combination of the Common-Sense Model of Self-Regulation and Bronfenbrenner’s Ecological Systems theory to conceptualize and organize these findings. A general lack of breast cancer knowledge was a major contributing factor to help-seeking delays among participants in the study. This finding was surprising considering that several breast cancer awareness campaigns have been run both nationally in South Africa and internationally. We call attention to the need for accessible breast cancer information at primary healthcare and community levels.

Digital breast tomosynthesis: sensitivity for cancer in younger symptomatic women

Objective: Full-field digital mammography (FFDM) has limited sensitivity for cancer in younger women with denser breasts. Digital breast tomosynthesis (DBT) can reduce the risk of cancer being obscured by overlying tissue. The primary study aim was to compare the sensitivity of FFDM, DBT and FFDM-plus-DBT in women under 60 years old with clinical suspicion of breast cancer. Methods: This multicentre study recruited 446 patients from UK breast clinics. Participants underwent both standard FFDM and DBT. A blinded retrospective multireader study involving 12 readers and 300 mammograms (152 malignant and 148 benign cases) was conducted. Results: Sensitivity for cancer was 86.6% with FFDM [95% CI (85.2–88.0%)], 89.1% with DBT [95% CI (88.2–90%)], and 91.7% with FFDM+DBT [95% CI (90.7–92.6%)]. In the densest breasts, the maximum sensitivity increment with FFDM +DBT over FFDM alone was 10.3%, varying by density measurement method. Overall specificity was 81.4% with FFDM [95% CI (80.5–82.3%)], 84.6% with DBT [95% CI (83.9–85.3%)], and 79.6% with FFDM +DBT [95% CI (79.0–80.2%)]. No differences were detected in accuracy of tumour measurement in unifocal cases. Conclusions: Where available, DBT merits first-line use in the under 60 age group in symptomatic breast clinics, particularly in women known to have very dense breasts. Advances in knowledge: This study is one of very few to address the accuracy of DBT in symptomatic rather than screening patients. It quantifies the diagnostic gains of DBT in direct comparison with standard digital mammography, supporting informed decisions on appropriate use of DBT in this population.
