Assessing the cost-effectiveness of waiting list reduction strategies for a breast radiology department: a real-life case study.

BACKGROUND: A timely diagnosis is essential for improving breast cancer patients' survival and designing targeted therapeutic plans. For this purpose, the screening timing, as well as the related waiting lists, are decisive. Nonetheless, even in economically advanced countries, breast cancer radiology centres fail in providing effective screening programs. Actually, a careful hospital governance should encourage waiting lists reduction programs, not only for improving patients care, but also for minimizing costs associated with the treatment of advanced cancers. Thus, in this work, we proposed a model to evaluate several scenarios for an optimal distribution of the resources invested in a Department of Breast Radiodiagnosis. MATERIALS AND METHODS: Particularly, we performed a cost-benefit analysis as a technology assessment method to estimate both costs and health effects of the screening program, to maximise both benefits related to the quality of care and resources employed by the Department of Breast Radiodiagnosis of Istituto Tumori "Giovanni Paolo II" of Bari in 2019. Specifically, we determined the Quality-Adjusted Life Year (QALY) for estimating health outcomes, in terms of usefulness of two hypothetical screening strategies with respect to the current one. While the first hypothetical strategy adds one team made up of a doctor, a technician and a nurse, along with an ultrasound and a mammograph, the second one adds two afternoon teams. RESULTS: This study showed that the most cost-effective incremental ratio could be achieved by reducing current waiting lists from 32 to 16 months. Finally, our analysis revealed that this strategy would also allow to include more people in the screening programs (60,000 patients in 3 years).

Breast radiology malpractice suits: Characteristics of frequency and outcomes- national and statewide distinctions.

The purpose of this study was to determine the frequency and outcomes of breast malpractice suits among all enrollees in One Call Medical Inc.'s panel of interpreting radiologists nationally and to evaluate state-by-state variations. The 8401 radiologists enrolled had 4764 suits, of which 826 were related to breast disease. In New York and New Jersey, the ratio of breast suits to One Call Radiologists was 0.28 and 0.27, twice as much as in any other state. Breast suits in radiology have a wide variation in frequency across the country with New York and New Jersey far exceeding all others in relative frequency and number of radiologists with multiple breast suits.

A perspective on how to optimize breast imaging rotations for medical students.

As educators we try to acquire and retain the attention of medical students who rotate through radiology in hopes to improve recruitment. There are various ways to optimize a medical student rotation in breast imaging. We review our methods of identifying their medical interest, highlighting the steps in breast intervention, selecting key cases for review, and providing meaningful feedback.

Patient Communication Innovations in Breast Imaging.

Effective patient communication is paramount in breast radiology, where standardized reporting and patient-centered care practices have long been established. This communication profoundly affects patient experience, well-being, and adherence to medical advice. Breast radiologists play a pivotal role in conveying diagnostic findings and addressing patient concerns, particularly in the context of cancer diagnoses. Technological advances in radiology reporting, patient access to electronic medical records, and the demand for immediate information access have reshaped radiologists' communication practices. Innovative approaches, including image-rich reports, visual timelines, and video radiology reports, have been used in various institutions to enhance patient comprehension and engagement.

Glass shards masquerading as calcifications in the breast: A case report.

Noniatrogenically acquired foreign bodies in the nipple-areola complex or breast skin are rare and can have variable imaging features, depending on the nature of the foreign material. We present the case of a 41-year-old female who had numerous apparent round and punctate calcifications in the right periareolar breast, predominantly within the skin. The biopsy showed multiple glass shards on a background of scar tissue. Further discussion with the patient confirmed that the glass shards were acquired during a motor vehicle accident several years earlier. We also review the types of foreign body material observed in the breast, the imaging appearance of glass foreign bodies in soft tissue, and methods of removal.

Mucocele-like Lesions: Radiologic-Pathologic Correlation.

Mucocele-like lesions (MLLs) of the breast are rare lesions described as dilated, mucin-filled cysts associated with rupture and extracellular mucin in the surrounding stroma. These lesions are of clinical concern because they can coexist with a spectrum of atypical and malignant findings, including atypical ductal hyperplasia, ductal carcinoma in situ, and invasive carcinoma including mucinous carcinoma. Imaging findings of MLLs are nonspecific and varied, although the most common initial finding is that of incidental coarse heterogeneous calcifications on mammography. Occasionally, an asymmetry or mass may be found with or without calcifications, and such MLLs have a higher rate of upgrade to malignancy at excision. Pathology findings are often descriptive given the small sample received from percutaneous biopsy, and the primary consideration is to report any associated atypia, including atypical ductal hyperplasia. There is consensus in the literature that MLLs with atypia on biopsy should undergo excision because of the average reported 17.5% (20/114) upgrade rate to malignancy. The upgrade rate for MLLs without atypia averages 4.1% (14/341). Therefore, imaging surveillance may be a reasonable alternative to excision for MLLs with no atypia on a case-by-case basis. We review MLL imaging findings, pathology findings, and clinical management and present 3 cases from our institution to add to the literature on these rare lesions.

Postoperative Complications Following Lumpectomy With Intraoperative X-Ray Radiation Therapy: A Retrospective Comparative Study.

BACKGROUND: Lumpectomy with intraoperative radiation (IORT) is a relatively new modality for the treatment of early breast cancer. IORT delivers targeted radiation to the tumor bed and obviates the need for external beam radiation (EBRT) in 85% of the cases. IORT is being used increasingly around the world, however information regarding early and late postoperative complications associated with the procedure is limited. AIM: To describe and compare complication rates after lumpectomy and IORT with those seen after lumpectomy and EBRT or lumpectomy alone. METHODS: Clinical, demographic, and histopathological data were collected from electronic medical records and a retrospectively maintained database. Postoperative complications were compared for patients undergoing lumpectomy with IORT, lumpectomy with EBRT, and lumpectomy alone over the same period. RESULTS: A total of 445 patients were included in the study: 113 underwent lumpectomy with IORT, 253 had lumpectomy followed by EBRT, and 79 had Lumpectomy alone. Postoperative seroma was documented in 74 patients (65%) after IORT,87 (34%) after EBRT, and 9 (11%) after lumpectomy alone (P = .000). Surgical site infection requiring antibiotic treatment was diagnosed in 26 patients (23%) after IORT, 38 (15%) after EBRT, and 5 (6%) after lumpectomy alone (P = .013). Postoperative erythema was documented in 39 patients (34%) after IORT, 40 (16%) after EBRT, and 5 (6%) after lumpectomy alone (P = .000). Postoperative minor complications such as scar and breast deformity, edema, Mondor's syndrome, and chronic tenderness, were documented in 62 patients (55%) after IORT, 119 (47%) after EBRT, and 13 (17%) after lumpectomy alone (P = .000). The average follow-up was 14 months. CONCLUSIONS: IORT is associated with an increased rate of postoperative complications compared to EBRT or lumpectomy alone. Most complications are minor and transient. We hypothesize that the increased occurrence of complications may also be attributed to overreporting, which is associated with the introduction of a new technology. Educating physicians and patients about potential complications and their course may help establish expectations and improve the management of postoperative complications.

Extramedullary relapse of acute myeloid leukemia in the breast: A radiological case report.

This report presents a unique case of a 42-year-old female with a history of acute myeloid leukemia (AML) who exhibited an extramedullary relapse in the breast. Given the rarity of such presentations, this case underscores the importance of considering AML in the differential diagnosis of breast lesions, especially in patients with a pertinent medical history. Additionally, this case highlights the radiological and pathological challenges in distinguishing AML from other breast malignancies. The importance of timely diagnosis and the clinical implications of such a presentation are also discussed.

The effect of polycystic ovarian syndrome on fibrocystic breast changes in postmenopausal women.

Background: Fibrocystic breast changes (FCCs) are benign lesions thought to be caused by an increased estrogen-to-progesterone ratio. One of the most common endocrinopathies that increases this ratio is polycystic ovarian syndrome (PCOS). Although nonproliferative FCCs do not increase the risk of breast cancer, they can make mammographic detection of malignancy in postmenopausal women more difficult. The aim of this study was to investigate the effects of PCOS on the development of postmenopausal FCCs. Methods: This retrospective cohort study used the TriNetX research network to identify two cohorts of postmenopausal women (Z78.0) older than 45, without a prior diagnosis of FCCs (N60.1) or hormone replacement therapy (Z79.890). One cohort included a diagnosis of PCOS (E28.2). The cohorts were balanced for age, race, ethnicity, and hormonally relevant comorbidities. The cohorts were then evaluated for the development of FCCs after menopause. Results: Postmenopausal patients with PCOS were 52% more likely to develop FCCs than those without PCOS (2.2% vs. 1.4%, relative risk 1.52, 95% confidence interval 1.05, 2.22, P = 0.03). Conclusion: Postmenopausal women with PCOS have a higher risk of developing FCCs. Further studies are needed to improve the differentiation of benign FCCs from malignant lesions on imaging for postmenopausal women with PCOS who develop FCCs.

Cryoablation for the Treatment of Breast Cancer: A Review of the Current Landscape and Future Possibilities.

Breast cancer is one of the most common malignancies worldwide. Traditional treatment options for breast cancer include surgery, radiation therapy, and chemotherapy. However, cryoablation, a minimally invasive technique, has emerged as a promising alternative for the treatment of early-stage breast cancer. This article aims to provide an overview of cryoablation, focusing on incorporation into practice, patient selection, procedural technique, imaging follow-up, post-treatment radiopathological findings, and current and ongoing research in the field. The current evidence suggests that cryoablation offers a safe and effective treatment option for selected patients, providing comparable oncological outcomes to traditional treatments while minimizing invasiveness and preserving breast aesthetics.

Independent evaluation of a multi-view multi-task convolutional neural network breast cancer classification model using Finnish mammography screening data.

BACKGROUND: Development of deep convolutional neural networks for breast cancer classification has taken significant steps towards clinical adoption. It is though unclear how the models perform for unseen data, and what is required to adapt them to different demographic populations. In this retrospective study, we adopt an openly available pre-trained mammography breast cancer multi-view classification model and evaluate it by utilizing an independent Finnish dataset. METHODS: Transfer learning was used, and the pre-trained model was finetuned with 8,829 examinations from the Finnish dataset (4,321 normal, 362 malignant and 4,146 benign examinations). Holdout dataset with 2,208 examinations from the Finnish dataset (1,082 normal, 70 malignant and 1,056 benign examinations) was used in the evaluation. The performance was also evaluated on a manually annotated malignant suspect subset. Receiver Operating Characteristic (ROC) and Precision-Recall curves were used to performance measures. RESULTS: The Area Under ROC [95%CI] values for malignancy classification obtained with the finetuned model for the entire holdout set were 0.82 [0.76, 0.87], 0.84 [0.77, 0.89], 0.85 [0.79, 0.90], and 0.83 [0.76, 0.89] for R-MLO, L-MLO, R-CC and L-CC views respectively. Performance on the malignant suspect subset was slightly better. On the auxiliary benign classification task performance remained low. CONCLUSIONS: The results indicate that the model performs well also in an out-of-distribution setting. Finetuning allowed the model to adapt to some of the underlying local demographics. Future research should concentrate to identify breast cancer subgroups adversely affecting performance, as it is a requirement for increasing the model's readiness level for a clinical setting.

Radiomics to Differentiate Malignant and Benign Breast Lesions: A Systematic Review and Diagnostic Test Accuracy Meta-Analysis.

Breast cancer is a prevalent global health concern, necessitating accurate diagnostic tools for effective management. Diagnostic imaging plays a pivotal role in breast cancer diagnosis, staging, treatment planning, and outcome evaluation. Radiomics is an emerging field of study in medical imaging that contains a broad set of computational methods to extract quantitative features from radiographic images. This can be utilized to guide diagnosis, treatment response, and prognosis in clinical settings.  A systematic review was performed in concordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and the Cochrane Handbook for Systematic Reviews of Diagnostic Test Accuracy. Quality was assessed using the radiomics quality score. Diagnostic sensitivity and specificity of radiomics analysis, with 95% confidence intervals (CIs), were included for meta-analysis. The area under the curve analysis was recorded. An extensive statistical analysis was performed following the Cochrane guidelines. Statistical significance was determined if p-values were less than 0.05. Statistical analyses were conducted using Review Manager (RevMan), Version 5.4.1. A total of 31 manuscripts involving 8,773 patients were included, with 17 contributing to the meta-analysis. The cohort comprised 56.2% malignant breast cancers and 43.8% benign breast lesions. MRI demonstrated a sensitivity of 0.91 (95% CI: 0.89-0.92) and a specificity of 0.84 (95% CI: 0.82-0.86) in differentiating between benign and malignant breast cancers. Mammography-based radiomic features predicted breast cancer subtype with a sensitivity of 0.79 (95% CI: 0.76-0.82) and a specificity of 0.81 (95% CI: 0.79-0.84). Ultrasound-based analysis yielded a sensitivity of 0.92 (95% CI: 0.90-0.94) and a specificity of 0.85 (95% CI: 0.83-0.88). Only one study reported the results of radiomic evaluation from CT, which had a sensitivity of 0.95 (95% CI: 0.88-0.99) and a specificity of 0.56 (95% CI: 0.45-0.67).  Across different imaging modalities, radiomics exhibited robust diagnostic accuracy in differentiating benign and malignant breast lesions. The results underscore the potential of radiomic assessment as a minimally invasive alternative or adjunctive diagnostic tool for breast cancer. This is pioneering data that reports on a novel diagnostic approach that is understudied and underreported. However, due to study limitations, the complexity of this technology, and the need for future development, biopsy still remains the current gold standard method of determining breast cancer type.

The Efficacy of Clinical Breast Exams and Breast Self-Exams in Detecting Malignancy or Positive Ultrasound Findings.

Objective A breast exam is a low-risk, low-cost method for early detection, which is crucial for improved mortality. However, clinical breast exams (CBE) and breast self-exams (BSEs) remain controversial with unclear guidelines. This study analyzes the efficacy of these two exam types in evaluating palpable breast masses. Methods This retrospective cross-sectional study included 2019 medical records from Epic of women with breast lumps. Patient demographics, provider types, and breast exam types were recorded. Primary outcomes were detection of cancer and positive ultrasound finding. Fisher's exact tests and two-sample t-tests determined the statistical significance of the association between the outcomes and categorical and continuous variables. Results Of 462 breast masses, 69 demonstrated positive ultrasound findings, with 26 of those yielding cancer; 96% of cancers and 81% of ultrasound findings resulted from patient-identified lumps. Of provider-identified lumps, 100% of cancers and 92.3% of positive ultrasound findings were diagnosed by MDs (doctors of medicine) rather than midlevel providers. There was no statistically significant difference in identifying cancer or positive ultrasound finding between CBEs and BSEs (p = 0.3709 and p = 0.1556). Conclusion Despite no difference between CBEs and BSEs in identifying cancer or positive ultrasound finding, 25 of the 26 breast cancers were initially detected by patients, while only one of 26 was detected by CBE. BSEs detect breast cancers. Although some guidelines encourage CBEs over self-exams, not all CBEs are equal. Key message There is no significant difference between CBEs and BSEs in identifying cancer or positive ultrasound finding. The majority of cancers were initially identified by patients. BSEs detect breast cancers and women should continue performing them. Not all CBEs are equal. CBEs by MDs, especially women health specialists, are generally more effective than those by midlevel providers.

Communicating With Breast Imaging Patients During the COVID-19 Pandemic: Impact on Patient Care and Physician Wellness.

OBJECTIVE: Assess the impact of COVID-19 on patient-breast radiologist interactions and evaluate the relationship between safety measure-constrained communication and physician wellbeing. METHODS: A 41-question survey on the perceived effect of COVID-19 on patient care was distributed from June 2020 to September 2020 to members of the Society of Breast Imaging and the National Consortium of Breast Centers. Non-radiologists and international members were excluded. Anxiety and psychological distress scores were calculated. A multivariable logistic model was used to identify demographic and mental health factors associated with responses. RESULTS: Five hundred twenty-five surveys met inclusion criteria (23% response rate). Diminished ability to fulfill patients' emotional needs was reported by 46% (221/479), a response associated with younger age (OR, 0.8 per decade; P < 0.01), higher anxiety (OR, 2.3; P < 0.01), and higher psychological distress (OR, 2.2; P = 0.04). Personal protective equipment made patient communication more difficult for 88% (422/478), a response associated with younger age (OR, 0.8 per decade; P = 0.008), female gender (OR, 1.9; P < 0.01), and greater anxiety (OR, 2.6; P = 0.001). The inability to provide the same level of care as prior to COVID-19 was reported by 37% (177/481) and was associated with greater anxiety (OR, 3.4; P < 0.001) and psychological distress (OR, 1.7; P = 0.03). CONCLUSION: The majority of breast radiologists reported that COVID-19 has had a negative impact on patient care. This perception was more likely among younger radiologists and those with higher levels of anxiety and psychological distress.

COVID-19 and Breast Radiologist Wellness: Impact of Gender, Financial Loss, and Childcare Need.

PURPOSE: The purpose of this study was to evaluate the emotional and financial impact of coronavirus disease 2019 (COVID-19) on breast radiologists to understand potential consequences on physician wellness and gender disparities in radiology. METHODS: A 41-question survey was distributed from June to September 2020 to members of the Society of Breast Imaging and the National Consortium of Breast Centers. Psychological distress and financial loss scores were calculated on the basis of survey responses and compared across gender and age subgroups. A multivariate logistic model was used to identify factors associated with psychological distress scores. RESULTS: A total of 628 surveys were completed (18% response rate); the mean respondent age was 52 ± 10 years, and 79% were women. Anxiety was reported by 68% of respondents, followed by sadness (41%), sleep problems (36%), anger (25%), and depression (23%). A higher psychological distress score correlated with female gender (odds ratio [OR], 1.9; P = .001), younger age (OR, 0.8 per SD; P = .005), and a higher financial loss score (OR, 1.4; P < .0001). Participants whose practices had not initiated wellness efforts specific to COVID-19 (54%) had higher psychological distress scores (OR, 1.4; P = .03). Of those with children at home, 38% reported increased childcare needs, higher in women than men (40% versus 29%, P < .001). Thirty-seven percent reported that childcare needs had adversely affected their jobs, which correlated with higher psychological distress scores (OR, 2.2-3.3; P < .05). CONCLUSIONS: Psychological distress was highest among younger and female respondents and those with greater pandemic-specific childcare needs and financial loss. Practice-initiated COVID-19-specific wellness efforts were associated with decreased psychological distress. Policies are needed to mitigate pandemic-specific burnout and worsening gender disparities.

Could Breast Tomosynthesis With Synthetic View Mammography Aid Standard Two-Dimensional Mammography in Evaluation at Symptomatic Triple Assessment Breast Clinics?

Background This study aimed to determine whether breast tomosynthesis and synthetic view mammography (SM) can aid standard two-dimensional mammography (S2DM) in the evaluation of symptomatic women at triple assessment clinics (TACs). Methodology Digital breast tomosynthesis (DBT), SM, and S2DM were performed on 400 patients at symptomatic breast TACs between September 2020 and November 2020. Diagnostic findings on mammography and ultrasound were retrospectively recorded and analyzed by a breast-trained radiologist with 13 years of clinical experience. Pathology results for all biopsies were recorded and correlated with the mammographic and ultrasound findings. Results The combination of DBT and SM was superior to S2DM in the following settings: calcifications were more conspicuous on SM than S2DM in 44% of patients with calcifications. Mass margins were better defined on DBT than S2DM in 71% of patients with masses. Distortion was more easily detectable in 11% of patients with distortion on SM and in 44% of patients with distortion on DBT compared with S2DM. All malignant lesions were identified on all modalities. Conclusions Combined DBT and SM demonstrated several advantages over S2DM alone. SM can provide equal and sometimes superior diagnostic performance with the added benefit of requiring no additional radiation exposure when synthesized from DBT data. We conclude that adding DBT and SM to S2DM aids in the assessment of symptomatic women, and omitting S2DM results in no loss of clinically relevant information for women presenting to symptomatic breast clinics.

Breast Imaging in the Time of COVID-19: A Singapore-based Breast Center's Experience in the Midst of a Pandemic.

The emergence of the COVID-19 pandemic presented new and yet uncharted challenges to the field of radiology, and consequently to breast imaging as a subspecialty. Maintaining a certain standard of care whilst ensuring the safety of patients and staff in our small Singapore-based breast imaging center are equally important and has resulted in modifications of our clinical practice and workflows. Screening patients for COVID-19 symptoms, risk factors, and potential exposure history has become paramount. Workflow changes have also included progressively deferring, and in some cases halting, nonessential services such as biopsies deemed to have a low risk of malignancy, routine follow-up imaging in postoperative patients or those with prior Breast Imaging Reporting and Data System 3 findings, and mammographic screening. Breast radiologists within our practice are also adapting to the changing landscape by playing a more active role in general radiology and emergency department reporting in order to reduce turnaround time and facilitate the discharge of inpatients. We have also enabled a sense of geographical segregation within our breast center to reduce potential exposure and cross-contamination risks. Although the near future remains uncertain, breast imaging within the broader scope of radiology practice will have to continually adjust to meet the ever-changing realities as this pandemic evolves.

Breast Metastases: Updates on Epidemiology and Radiologic Findings.

Purpose The aim of this study was to report the prevalence of secondary breast malignancies and analyze their radiological characteristics. Materials and methods We collected 42,505 pathological reports of mammary biopsies performed from January 2000 to January 2019 in our hospital database, from which we screened reports of secondary cancer of the breast. We collected and analyzed imaging data from computed tomography (CT), ultrasound (US), and mammography. Mammograms, CT scans, and US images were reviewed by two breast radiologists. Prevalence of secondary breast malignancy among suspicious breast masses and all breast malignancies were calculated. Results Out of 42,505 histopathology reports from mammary biopsies, we found 19,354 malignancies. We identified 33 cases of secondary breast cancers (0.08% of suspicious breast lesions, 0.17% of breast malignancies). Most common metastases were from lymphoma (23 cases, 0.05% of suspicious breast lesions, 0.12% of breast malignancies) and melanoma (six cases, 0.01% of suspicious breast lesions, 0.03% of breast malignancies). All secondary lesions were hypoechoic on US and showed high density on mammogram. On CT, 83% of the lesions appeared solid/dense, and 17% were mixed, alternating areas of iso/hyperdensity with areas of hypodensity. Conclusion Secondary breast cancer had a prevalence of 0.17% among all breast malignancies. No specific imaging features, characteristic of secondary breast cancer, were found.

Pseudoangiomatous Stromal Hyperplasia of the Breast: A Rare Finding in a Male Patient.

Pseudoangiomatous stromal hyperplasia (PASH) in male patients is a rare condition that represents a hormonally-induced proliferation of mesenchymal tissue of the breast. This benign pathology is often undiagnosed due to many reasons. When PASH presents as a breast mass, it appears innocent, developing as a smooth and well-circumscribed tumor. Furthermore, it does not elicit suspicious findings on imaging. These points often halt further investigation of many breast abnormalities. Breast masses are statistically most likely to be gynecomastia when they arise in men. However, they are important to investigate because, although rare, breast cancer can occur in men. Furthermore, the benign conditions of the breast that commonly affect women can also impact male patients. It is oftentimes overlooked that men too can experience hormonal stimulation of the breast tissue. The following case describes this rare but important instance of a male patient diagnosed with PASH following a previous diagnosis of infiltrative ductal carcinoma in situ of the contralateral breast.

How Many of the Biopsy Decisions Taken at Inexperienced Breast Radiology Units Were Correct?

OBJECTIVE: In this study, we aimed to determine the need for biopsy in patients referred from other clinics for the performance of biopsy with the suspicion of breast cancer. MATERIALS AND METHODS: 112 patients were included in the study. It was decided that their biopsies be performed following examinations in other clinics and they presented to the breast radiology unit of our hospital for a second opinion. The demographic characteristics, diagnostic studies completed in the other centers, properties of lesions, decision made as a result of examinations and BI-RADS (Breast Imaging Reporting and Data Systems) categorizations were recorded on the registration forms of the study patients. In addition, the quality of examinations, reasons of repeat tests, additional tests features and the last decision of our clinic were documented. The obtained data were analyzed in terms of re-examination, additional tests and change in the biopsy decision. Changes in the biopsy decisions for patients were specifically inquired. RESULTS: The biopsy decisions were cancelled in our breast radiology unit for 63 out of 112 patients (56.3%) whose biopsy decisions were made at an external institute. For 42 patients, examinations made by the other clinics were deemed adequate, yet there was no need for biopsy in 22 of them. The biopsy decisions were cancelled for 27 out of 47 patients (57.4%) with repeat examination and 18 out of 28 patients (64.3%) with additional tests because of the insufficient test quality. CONCLUSION: Incorrect, inadequate breast screening and false positivity were higher at inexperienced institutes.
