Pattern of breast cancer presentation during the coronavirus disease pandemic: results from a cohort study in the UK

Background: This study aimed to explore the hypothesis that the stage of breast cancer at initial diagnosis in 2020 is more advanced compared with 2019. Methods: Tumor, node, metastasis and Union for International Cancer Control (UICC) stages of new breast cancer diagnoses at the Bucks Breast Unit from May to October 2019 and 2020 were reviewed. A p < 0.05 was considered significant. Results: Average UICC stage increased from 1a in 2019 to 2a in 2020 (p < 0.01). Excluding cancers detected through screening, UICC stage still increased from 1b in 2019 to 2a in 2020 (p = 0.0184). There was a significant increase in the percentage of node-positive patients (p = 0.0063) and patients with metastatic disease (p = 0.0295) on initial presentation. Conclusion: Overall, patients presented with higher UICC stages and more node-positive and metastatic disease on initial diagnosis in 2020 compared with 2019.

Cost analysis of managing B3 breast lesions by vacuum excision at Leeds Breast Unit using a decision model

ObjectiveTo develop an economic model to evaluate the cost of using vacuum-assisted excision (VAE) for managing B3 breast lesions.DesignA decision tree of managing B3 breast lesions was developed to compare the costs of VAE with diagnostic excision (DE) from the perspective of the healthcare provider. Two different diagnostic pathways were compared which describe alternative approaches to the management of B3 lesions using inputs derived from a mix of primary and secondary data.SettingBased on a study conducted at Leeds Breast Unit, UK.Participants398 patients enter the model having undergone initial core needle biopsy, or vacuum-assisted biopsy, and diagnosed with B3 breast lesion.Main outcome measuresThe economic impact, in terms of cost, of various scenarios using analysis of extremes and probabilistic sensitivity analysis.ResultsVAE reduced the cost per patient by £1510.75. Analysis of extremes showed that managing B3 lesions using VAE was cost saving except the case where a combination of the highest cost associated with VAE and the lowest cost for DE were used. Probabilistic sensitivity analysis showed that using VAE for managing B3 lesions has a probability of 0.9 of being cost saving compared with using DE.ConclusionThis analysis shows the potential cost saving of using VAE as an alternative for managing B3 breast lesions compared with DE. Further research in this area and the effect of the VAE on patients’ quality of life is warranted.

The management of a breast unit during the COVID-19 emergency: a local experience

Introduction: Since breast imaging requires very close contact with patients, a protocol is needed to perform safe daily screening activities during the COVID-19 pandemic. Materials and methods: Patients were triaged and separated into three different clinical scenarios by performing a telephone questionnaire before each diagnostic exam or a nasopharyngeal swab before every recovery. Specific procedures for each scenario are described. Results: From July to October 2020, 994 exams were performed. A total of 16 cancers and 7 suspected COVID-19 patients were identified. No medical were was infected. Conclusion: This protocol is an example of the practical use of guidelines applied to a breast unit to assist specialists in preventing COVID-19 infection and optimizing resources for breast cancer diagnosis.

Protocol for Prevention and Monitoring of Surgical Site Infections in Implant-Based Breast Reconstruction: Preliminary Results

Surgical site infection in implant-based breast reconstruction is a complication with variable incidence reported in the literature. Due to potential loss of implant and reconstruction, it can have a strong psychological impact on patients. Background and objectives: This study aimed primarily at analyzing the current status of the surgical site infection (SSI), (type, time of onset, clinical presentation, pathogens and management) in patients who underwent implant-based breast reconstruction at our Breast Unit. Secondarily, we wanted to establish whether introduction of a new, updated evidence-based protocol for infection prevention can reduce SSI in implant-based breast reconstruction. Materials and Methods: A single-center retrospective study was performed primarily to evaluate the incidence and features of SSI after implant-based breast reconstruction from 2007 to 2020. In June 2020, a protocol for prevention of SSI in implant-based breast reconstruction was introduced in clinical practice. Secondarily, a data analysis of all patients who underwent implant-based breast reconstruction in compliance with this protocol was performed after preliminarily assessing its efficacy. Results: 756 women were evaluated after mastectomy and implant-based breast reconstruction for breast cancer. A total of 26 surgical site infections were detected. The annual incidence of SSI decreased over time (range 0–11.76%). Data relating to infections’ features, involved pathogens and implemented treatments were obtained. Since the introduction of the protocol, 22 patients have been evaluated, for a total of 29 implants. No early infections occurred. Conclusions: Surgical site infection rates at our Breast Unit are comparable to those reported in the literature. The SSI rates have shown a decreasing trend over the years. No SSI has occurred since the introduction of the prevention protocol for surgical site infection in June 2020.

Radiology management of a ‘breast unit’ during COVID-19 pandemic: a single institution experience

Aim: To describe the activity in the ‘breast unit’ at the department of radiology during the COVID-19 lockdown in a university hospital treating COVID-19 patients in a Middle-Eastern developing country. Materials: This was a retrospective study conducted from March 9 until 11 May 2020, in the breast unit at the department of radiology of a central university hospital in a Middle-Eastern developing country. Data were collected from 205 patients visiting the breast unit during the lockdown period and compared with the activity in the same period in the previous year. Results: Reduction of the breast unit activity was estimated at 73%. In addition, 153 mammograms, 205 ultrasounds, and 16 breast MRIs were done. Indications for mammogram were screening (41.5%), follow-up (22%), clinical symptoms (20%) and breast cancer surveillance (16.5%). MRI was performed mostly for preoperative surgical management. The rate of positive biopsies was 41%. All staff members and patients have accommodated to new adjustments. Conclusion: Activity in the breast unit dropped during the lockdown period. Staff should continue to seek their own and their patient’s safety without diminishing the quality of healthcare.
