Vanishing Act: A Case Report of Missing Breast Tumour Marker.

Breast tissue markers are essential in localising tumours post-neoadjuvant chemotherapy prior to breast-conserving surgery. However, due to the advancement in neoadjuvant therapies, greater efficacy in reducing tumour size increases the possibility of marker migration, potentially compromising surgical outcomes. We report a case of a 34-year-old woman with left breast invasive carcinoma, where the tissue marker, placed under ultrasound guidance before chemotherapy, migrated and was undetectable after eight chemotherapy cycles. The delay in surgery was resolved by identifying the marker in the left pectoral muscle using CT, though proximity to the lung prevented hook wire placement. Proposed migration mechanisms include the "accordion effect" and haematoma-induced displacement, highlighting the dynamic nature of breast tissue. Various imaging modalities, such as mammography, ultrasound, and CT, have proven helpful for marker localisation. This case underscores the need for a deeper understanding of tissue dynamics and emphasises interdisciplinary communication to adapt treatment strategies. As medical knowledge continues to evolve, insights are needed to refine best practices in breast cancer management and radiological interventions.

Immediate Latissimus Dorsi Flap Reconstruction: Assessing Aesthetic Outcomes Following Mastectomy in Breast Cancer Patients.

BACKGROUND:  Breast Cancer has now become the leading cause of cancer-related deaths among women. In a traditional radical mastectomy, there can be complications that may affect the physiological characteristics of the breast and subsequently cause profound psychological stress to the patients. Hence, latissimus dorsi (LD) flap reconstruction provides an aesthetic approach in patients undergoing mastectomy. The goal is to maximize the flap's soft tissue coverage while minimizing the magnitude of donor site defect and complication. METHODS: A prospective observational study was conducted in the Department of General Surgery, Safdarjung Hospital, New Delhi, India, where 30 breast cancer patients were enrolled and had undergone mastectomy with immediate LD flap reconstruction. Cosmetic assessments using BREAST-Q questionnaires were conducted postoperatively at various intervals starting from postoperative day one, week two, and week six. The subjective evaluation was done by the patient, while a blinded nurse and surgeon did the objective assessment. RESULT:  The majority (n=23, 76.7%) were aged 31-50 years. Initial postoperative BREAST-Q scores declined but significantly improved by week six, attributed to gradual wound healing over time, resulting in improved breast shape and contour. The objective scoring done by the blinded surgeon and nurse improved at six weeks compared to two weeks postoperatively. Almost similar outcomes were observed between preoperative and six-week postoperative scores with a significant overall p-value of <0.001. No significant statistical differences were noted between blinded surgeons and nurses for objective scoring. CONCLUSION:  The rising trend of breast cancer in younger demographics emphasizes the importance of balancing cosmetic satisfaction with oncological outcomes. Immediate LD flap breast reconstruction provides a reliable means for soft tissue coverage with acceptable perioperative morbidities for patients undergoing mastectomy. Complication rates were acceptable, with donor site seroma, surgical site infection (SSI), and shoulder weakness among them. They could be prevented or treated (prolonged drain in situ, quilting sutures, and seroma aspiration) or resolved with time (SSI and shoulder function).

Accuracy of MRI Versus PET/CT in the Prediction of Treatment Response to Neoadjuvant Chemotherapy in Breast Cancer.

Background Breast-conserving surgeries have significantly advanced breast cancer treatment, offering favorable oncological outcomes, enhanced cosmetic results, reduced postoperative morbidity, and better psychological acceptance compared to mastectomy. The introduction of neoadjuvant therapy has expanded the applicability of breast conservation surgery to include locally advanced tumors. Tumor response to neoadjuvant chemotherapy is evaluated using imaging modalities such as breast ultrasound, breast magnetic resonance imaging (MRI), and positron emission tomography/computed tomography (PET/CT). Accurate prediction of therapeutic response facilitates the planning of surgical and adjuvant treatments. This study aims to compare the diagnostic accuracy of MRI and PET/CT in predicting treatment response to neoadjuvant chemotherapy in breast cancer patients. Methods This retrospective study was conducted at a tertiary care center in Bahrain. A total of 138 patients with locally advanced breast cancer or human epidermal growth factor receptor-2 (HER2) positive, hormone receptor-negative cancers who underwent breast-conserving surgeries between June 2018 and December 2022 were included. The inclusion criteria focused on patients achieving a complete pathological response following neoadjuvant systemic therapy, ensuring a homogenous study population. Patients with hormone receptor-positive early breast cancers or metastatic tumors, ineligible for neoadjuvant chemotherapy, were excluded. Non-responders and partial responders were also excluded from the study. Statistical analysis was performed using IBM SPSS v26.0 (IBM Corp., Armonk, US). Response rates for the imaging modalities and histopathology results were assessed. Agreement between histology and imaging modalities was computed using kappa statistics. Diagnostic performance for predicting "no residual" disease was evaluated using the McNemar Test. All tests were two-tailed, with a p-value <0.05 considered statistically significant. Results The study included 138 patients, of whom 73 (52.9%) had an incomplete response or residual disease, while 65 (47.1%) had a complete response or no residual disease according to histology reports. There was slight agreement between post-neoadjuvant MRI and histology results (Cohen's kappa 0.172, p=0.010), while substantial agreement was observed between post-neoadjuvant PET/CT and histology results (Cohen's kappa 0.614, p=0.000). PET/CT demonstrated a higher sensitivity of 93.8% (p<0.001) and a specificity of 68.5%. Although MRI was more specific, the positive predictive value was comparable for both PET/CT and MRI. Conclusion PET/CT shows higher sensitivity and can serve as an early marker for predicting complete pathological response in post-neoadjuvant breast cancer patients. However, the prediction of residual disease is optimized by combining both MRI and PET/CT as diagnostic modalities.

Pathologic Complete Response to Neoadjuvant Chemotherapy and Pembrolizumab in Postpartum High-Risk Basal-Type Breast Cancer.

Neoadjuvant chemoimmunotherapy with pembrolizumab now defines the standard of care for early high-risk triple-negative breast cancer (TNBC). However, the role of pembrolizumab in neoadjuvant therapy (NAT) for estrogen receptor-positive (ER+) breast cancer remains uncertain. A 39-year-old G2P2 female discovered a palpable mass in the right breast while breastfeeding her 7-month-old child, leading to the diagnosis of a high-grade ER+ (80% moderate staining), human epidermal growth factor receptor 2-negative (ErbB2-) invasive ductal carcinoma with axillary nodal involvement. Gene expression profiling with the MammaPrint 70-gene signature and BluePrint 80-gene signature revealed a tumor with high-risk, basal-type biology. The multidisciplinary breast cancer team recommended NAT with pembrolizumab, carboplatin, paclitaxel, doxorubicin, and cyclophosphamide. Within six weeks, the patient exhibited a remarkable response, with no palpable mass or lymph node, and post-treatment examinations confirmed a complete clinical and radiologic response. The patient underwent lumpectomy and sentinel lymph node biopsy, revealing a pathological complete response with minimal ductal carcinoma in situ and negative axillary nodes. Adjuvant radiation therapy was administered, and the patient completed adjuvant pembrolizumab, currently showing no evidence of recurrence. This case underscores the potential benefits of neoadjuvant chemoimmunotherapy for patients with ER+ErbB2- high-risk, basal-type breast cancer. The use of immunotherapy in patients with pregnancy-associated breast cancer remains to be further investigated.

Exploring the Clinical Impact of RANK Pathway Inhibition in Advanced Breast Cancer: Insights From a Retrospective Study on CDK4/6 Inhibitors and Antiresorptive Therapy.

BACKGROUND AND OBJECTIVE: Breast cancer (BC) remains a significant health concern, particularly in advanced stages where the prognosis is poor. The combination of endocrine therapy (ET) with cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) has improved outcomes for advanced BC (aBC) patients. However, resistance to CDK4/6i remains a challenge, with no validated biomarkers to predict response. The receptor activator of the nuclear factor-kB (RANK) pathway has emerged as a key player in aBC, particularly in luminal BC. RANK overexpression has been associated with aggressive phenotypes and resistance to therapy. In view of these findings, we proceeded to investigate the potential involvement of the RANK pathway in luminal BC resistance to CDK4/6i. The objective was to evaluate the effectiveness of denosumab in increasing overall survival (OS) and progression-free survival (PFS). METHODS: In this retrospective analysis, 158 BC patients with bone metastases were included. Patients with human epidermal growth factor receptor-2 (HER2)-negative and hormone receptor-positive BC who received palbociclib or ribociclib in addition to antiresorptive medication were included. Patients received either denosumab or zoledronic acid (ZA) therapy. The primary endpoint was OS, with PFS as a secondary endpoint. RESULTS: Although the PFS and OS of denosumab were better than ZA in this study, it did not show a significant difference between the two drugs. Meanwhile, mOS was not achievable in patients in the denosumab group, while it was 34.1 months in patients in the ZA group. The hazard ratio (HR) showed a significant improvement for the denosumab group in patients under 60 of age (HR: 0.33, p<0.01), patients with a score of 1 HER2 overexpression (HR: 0.09, p=0.01), and patients with resistant endocrine (HR: 0.42, p=0.02) compared to ZA. CONCLUSION: This study highlights the potential clinical relevance of the RANK pathway in BC treatment, and our findings suggest that denosumab may offer significant benefits in terms of PFS and OS for certain subgroups, particularly those with HER2 scores of 1, patients under 60, and those with endocrine-resistant BC. In conclusion, considering that RANK pathway status may be a predictive biomarker for CDK4/6i treatment and may cause treatment resistance, our results demonstrate the clinical relevance of the combination of CDK4/6i + ET with RANKL inhibition.

Racial disparities in breast cancer risk factors and risk management.

Racial disparities in breast cancer outcomes are well described across the spectrum of screening, diagnosis, treatment, and survivorship. Breast cancer mortality is markedly elevated for Non-Hispanic Black women compared with other racial and ethnic groups, with multifactorial causes. Here, we aim to reduce this burden by identifying disparities in breast cancer risk factors, risk assessment, and risk management before breast cancer is diagnosed. We describe a reproductive profile and modifiable risk factors specific to the development of triple-negative breast cancer. We also propose that screening strategies should be both risk- and race-based, given the prevalence of early-onset triple-negative breast cancer in young Black women. We emphasize the importance of early risk assessment and identification of patients at hereditary and familial risk and discuss indications for a high-risk referral. We discuss the subtleties following genetic testing and highlight "uncertain" genetic testing results and risk estimation challenges in women who test negative. We trace aspects of the obesity epidemic in the Black community to infant feeding patterns and emphasize healthy eating and activity. Finally, we discuss building an environment of trust to foster adherence to recommendations, follow-up care, and participation in clinical trials. Addressing relevant social determinants of health; educating patients and clinicians on factors impacting disparities in outcomes; and encouraging participation in targeted, culturally sensitive research are essential to best serve all communities.

Management of Breast Intraductal Papilloma Diagnosed on Core Needle Biopsy: Excision or Follow-up?

Introduction Management of intraductal papillomas (IDPs) diagnosed on core needle biopsy (CNB) remains controversial. We report our experience of IDPs identified on CNB, our institutional rates of upgradation to atypia/malignancy as well as radiologic/pathologic features that may allow selection for surgery as well as those for safe observation. Methods The study is a retrospective review of patient records from 2012 to 2019, at a tertiary care hospital in Pakistan. Data was analyzed using Statistical Package for Social Sciences (SPSS), version 21.0 (IBM Corp., Armonk, NY). Associations between various patient factors were assessed using Pearson's chi-square test. Results This study included a total of 55 female patients with IDPs, with a mean age of 54.67 ± 15.57 years. On CNB, 69.1% (n = 38) of patients had IDP without atypia while 30.9% (n = 17) had IDP with atypia, with single IDPs being the most common lesions on excisional biopsy. Overall, of all CNB-diagnosed IDPs, only 4/55 (7.3%) demonstrated upgradation (3/4 to DCIS, 1/4 showed atypia) on excisional biopsy, and all these upgraded cases had failed to demonstrate atypia on initial CNB. Conclusion CNB-identified cases of IDPs are rarely upgraded on excision and thus routine excision in all cases may be unnecessary. Appropriate patient selection based on radiology-pathology findings should be done. Those with suspicious findings on imaging as well as those that demonstrate atypia on CNB must be excised.

Menopausal Symptoms and Utian Quality of Life Scale Following a Breast Cancer Diagnosis and Its Impact on Endocrine Adherence.

Introduction Standard treatment for oestrogen-positive breast cancers involves a minimum of five years of adjuvant endocrine treatment with a significant improvement in survival. However, the side effects of endocrine treatments are often underestimated. We aimed to identify the frequency of side effects, adherence to treatment, and impact on the quality of life of breast cancer survivors. Methods All patients attending holistic needs assessment and health and wellbeing events with a clinical nurse specialist between March and October 2023 were given a menopause symptom proforma and Utian menopausal quality of life scale questionnaire. Results A total of 99/150 (66%) patients attending a health needs assessment with a clinical nurse specialist following a diagnosis of breast cancer returned forms. The mean age of respondents was 56.7 years, with a mean 2.5-year duration since diagnosis. Thirty-seven percent of respondents were premenopausal at diagnosis, and 63% were postmenopausal. Five percent stopped treatment early due to menopausal symptoms, and 2.2% changed endocrine treatment. Overall, the mean menopausal quality of life score was -0.454 (p=0.0052). Within the premenopausal cohort, 84% reported hot flushes, 81% a low-sex drive, 73% night sweats, 89% memory problems, 89% fatigue, and 76% joint aches. This group scored -0.20 SD on the quality of life scale. The postmenopausal group reported a 71% incidence of hot flushes, 79% both poor sleep and joint pain, 60% breast pain, and 86% fatigue. They demonstrated a mean of -0.58 SD on the quality of life scale. The failure to adhere to endocrine treatment was reported by 6% of respondents, who cited side effects as the reason for non-compliance. Conclusion In conclusion, there is a significant increase in menopausal symptoms following treatment for breast cancer, which is negatively impacting well-being, quality of life, and endocrine adherence.

Histopathological Patterns and Outcomes of Triple-Positive Versus Triple-Negative Breast Cancer: A Retrospective Study at a Tertiary Cancer Center.

Background One of the leading causes of cancer-related deaths in females under 45 years old is breast cancer (BC). The definition of triple-negative breast cancer (TNBC) is the lack of expression of estrogen receptors (ERs) as well as progesterone receptors (PRs) and Erb-B2 receptor tyrosine kinase 2 (HER2) gene amplification. Triple-positive breast cancer (TPBC), on the other hand, is defined as tumors expressing a high level of ER, PR, and HER2 receptors. This study aims to assess the phenotypes of TNBC and TPBC by comparing their individual clinical behavior patterns and prognosis throughout the course of the disease in a tertiary cancer center in the Kingdom of Saudi Arabia (KSA). Methods Our study is a retrospective study using electronic medical records (EMRs) to identify all female patients diagnosed with BC using the International Classification of Diseases-10 (ICD-10) codes (between C50 and C50.9). About 1209 cases with primary BC female patients were recognized based on histopathology reports. Further subclassification into TPBC and TNBC was performed. Statistical analysis was performed using Rv3.6.2 (R Studio, version 3.5.2, Boston, MA, USA). The descriptive data were presented as means and standard deviations (SD). Survival curves were approximated using the Kaplan-Meier method. The comparison between survival curves between both groups was achieved using the log-rank test. The multivariate model was constructed based on the identified predictors using univariate analysis. Results Univariate analysis of overall survival (OS) showed that mortality was higher in TNBC compared to TPBC (HR = 2.82, P-value <0.05). However, in a multivariate analysis, molecular subtypes did not show a significant effect on OS with a P-value of 0.94. We found that age at diagnosis has been associated with a 4% increase in mortality risk with a yearly rise in age. Conclusion In this limited retrospective cohort study, we found that TNBC may not be associated with a higher risk of death than TPBC. However, other factors, including age at diagnosis, surgical intervention, and lymphovascular invasion (LVI), have been observed to increase the risk of mortality. On the other hand, patients with TNBC were found to have a worse prognosis in terms of local recurrence. This information cannot be generalized to all patients with BC given the limitations of this study. Further, larger cohorts are needed to explore biological and treatment-related outcomes in patients with TNBC and TPBC.

Racial disparity in breast cancer survivorship: themes from a series of four national healthcare provider live virtual forums.

PURPOSE: Significant disparity exists in the diagnosis, treatment, and survivorship outcomes among Black breast cancer (BC) survivors. Black BC survivors have more significant survivorship issues and a greater burden of illness than White counterparts. Barriers to rehabilitation exist for all BC survivors but are magnified in Black BC survivors. The purpose of this qualitative research was to document patient, clinician, and researchers' perceptions surrounding contributing factors, lived experiences, and potential solutions to racial disparity in BC survivorship. METHODS: A narrative approach was utilized to identify themes from a series of four virtual healthcare provider forums that explored lived personal and professional experiences, issues, and potential solutions surrounding racial disparity in BC survivorship. Forums included perspectives of patients, healthcare providers, researchers, and stakeholders in the BC field. An independent thematic analysis was performed by the investigators, all of whom have emic perspectives with respect to race and/or BC. RESULTS: Three main themes were identified related to racial disparity in BC survivorship: (1) societal and cultural contributing factors, (2) contribution of healthcare providers and systems, and (3) models of care and research considerations. CONCLUSIONS: The findings provide compelling documentation of lived personal and professional experiences of racial disparity in BC survivorship. Potential solutions exist and must be enacted immediately to ensure equitable survivorship outcomes for Black individuals following a BC diagnosis. IMPLICATIONS FOR CANCER SURVIVORS: Increased awareness related to racial disparity in BC survivorship among survivors, healthcare providers, and researchers will contribute to health equity and improved outcomes for Black individuals.

Effect of Psychosocial, Behavioral, and Disease Characteristics on Health-Related Quality of Life (HRQoL) After Breast Cancer Surgery: A Cross-Sectional Study of a Regional Australian Population.

BACKGROUND:  Increasing long-term breast cancer survivorship has highlighted the importance of patient-reported outcomes such as health-related quality of life (HRQoL) in addition to traditional outcomes that were used to define successful operative management. This study aimed to describe HRQoL in patients who underwent breast cancer resection in a regional Australian setting and identify the psychosocial, demographic, and operative characteristics associated with poor HRQoL. METHODS:  Consecutive patients who underwent breast cancer resection between 2015 and 2022 were included. Patients were asked to complete a survey instrument that included validated measures of HRQoL, emotional distress, fear of cancer recurrence (FCR), and social support. Demographic, disease, and operative data were collected from the medical record of the respondents. RESULTS:  Forty-six patients completed the survey (100% female, mean age = 62.68 years). Most HRQoL domains were significantly lower than an Australian reference population. HRQoL was more strongly associated with psychosocial factors (emotional distress, FCR, and social support) but was also associated with socioeconomic status, stage of cancer at presentation, and surgical complications. HRQoL was not related to breast conservation, management of the Axilla, or time since operation. CONCLUSION:  Long-term changes in HRQoL should be considered during the management and surveillance of breast cancer patients in regional Australia.

Racial Disparities in Clinical Outcomes on Investigator-Initiated Breast Cancer Clinical Trials at an Urban Medical Center.

BACKGROUND: Black women are 40% more likely to die of breast cancer compared to White women. Inadequate representation of Black patients in clinical trials may contribute to health care inequity. We aimed to assess breast cancer clinical outcomes in Non-Hispanic Black (Black) versus Non-Hispanic White (White) women with metastatic breast cancer (MBC) enrolled on investigator-initiated clinical trials at Winship Cancer Institute at Emory University, given the significant number of patients from underrepresented minority groups seen at Winship. MATERIALS AND METHODS: Black and White women with MBC on investigator-initiated trials at Emory between 2009 and 2019 were retrospectively evaluated. Univariate analyses and multiple logistic regression models were used to assess clinical response and treatment toxicities. Differences in overall survival between groups was assessed using quantile analysis. RESULTS: Sixty-two women with MBC were included (66% White vs. 34% Black). Black patients had less clinical benefit from the trial therapy as only 57% had partial response or stable disease as best response compared to 78% of White women (P = .09). Quantile analysis showed significant difference in mean survival between Whites and Blacks by the end of follow up (64 vs. 38 months). There were no significant differences in toxicities between groups. CONCLUSION: Participation rates of Black women with MBC on investigator-initiated clinical trials at an urban cancer center were higher compared to key national trials. Black women had worse treatment response and survival. These results reinforce the need for assessment of tumor differences by ancestry and continued improvement in minority representation on clinical trials.

Breast cancer outcomes in a private hospital appear better than national outcomes in a country with a mixed public/private healthcare model.

BACKGROUND: Ireland has a mixed model of healthcare delivery with a public healthcare system funded by general taxation and a large private healthcare insurance system, covering 43% of the population in 2012 and 2016. We set out to examine disparities in outcomes among patients with breast cancer treated in a private hospital compared to national outcomes over a comparable period. METHODS: Medical records of patients diagnosed with early (Stage 1-3 as per AJCC version 5) breast cancer between 2010 and 2015 at Bon Secours Hospital, Cork, Ireland were reviewed. Staging was confirmed and 5-year disease specific survival (DSS) and overall survival (OS) were calculated. DSS was compared to 5-year net survival (NS) figures from the National Cancer Registry of Ireland (NCRI) for a comparable period (2010-2014). RESULTS: DSS (Bon Secours) and NS (NCRI) are summarized in Table 5 and Fig. 2. 5-year survival figures are numerically higher in the private hospital compared with national data for individual stage. Taking stages 1 to 3 combined, the 95% confidence intervals do not cross, indicating statistical significance. CONCLUSIONS: We found evidence of superior outcomes in patients with early breast cancer treated at a private hospital compared with national outcome figures. This was demonstrated in 'all comers' (stages 1-3 combined), and particularly in patients with stage 3 breast cancer. Potential reasons for this disparity include differences in socioeconomic status, health-seeking behaviours and/or underlying health status between the two populations included. Differences in extent or timeliness of access to therapies may also contribute.

The Clinicopathological Significance of BiP/GRP-78 in Breast Cancer: A Meta-Analysis of Public Datasets and Immunohistochemical Detection.

The endoplasmic reticulum chaperone BiP (also known as GRP-78 or HSPA5) maintains protein folding to allow cell proliferation and survival and has been implicated in carcinogenesis, tumor progression, and therapy resistance. BiP's association with clinical factors and prognostic potential in breast cancer remains unclear. In this work, three types of analysis were conducted to improve the knowledge of BiP's clinicopathological potential: (1) analysis of publicly available RNA-seq and proteomics datasets stratified as high and low quartiles; (2) a systematic review and meta-analysis of immunohistochemical detection of BIP; (3) confirmation of findings by BiP immunohistochemical detection in two luminal-like breast cancer small cohorts of paired samples (pre- vs. post-endocrine therapy, and primary pre- vs. metastasis post-endocrine therapy). The TCGA PanCancer dataset and CPTAC showed groups with high BiP mRNA and protein associated with HER2, basal-like subtypes, and higher immune scores. The meta-analysis of BiP immunohistochemistry disclosed an association between higher BiP positivity and reduced relapse-free survival. BiP immunohistochemistry confirmed increased BiP expression in metastasis, an association of BiP positivity with HER2 expression, and nuclear BiP localization with higher a tumor stage and poor outcome. Therefore, three independent approaches showed that BiP protein is associated with worse outcomes and holds prognostic potential for breast cancer.

Second Opinions in Breast Cancer Surgery: What Have We Learned?

Introduction Second-opinion consultations (SOCs) provide many benefits. However, duplicate office visits and the logistics of transferring medical records may be concerning for delaying treatment. There is currently no clear understanding regarding the characteristics of patients with breast cancer who desire second surgical opinions or if this contributes to delays in care. Methods A review of our institutional database from July 1, 2019, to December 31, 2019, identified breast cancer patients who were documented to be SOCs or primary consultations (PC). Neoadjuvant chemotherapy patients were excluded. Comparisons of patient characteristics, tumor characteristics, and surgery factors were performed using chi-square analysis. All analyses were two-tailed and statistical significance was assigned at p <0.05. This study was deemed IRB-exempt. Results In our review, 158 breast cancer patients were identified, 21 (13.3%) SOCs and 137 (86.7%) PCs. Of the SOCs, 90% (19/21) underwent surgery at our institution. The study revealed an increased incidence of SOCs in those patients who ultimately underwent mastectomy (p=0.039) as well as those with lower pathologic T stage (p=0.021). There were no other differences in demographics, surgery, or tumor characteristics. No delay was seen in time for treatment. Conclusions Patients who sought second opinions were more likely to undergo mastectomy and had lower pathologic tumor size. The time from biopsy to surgery appointment was longer in patients who sought second opinions but there were no differences in the time from biopsy or surgery appointment. It is encouraging that those who sought second opinions did not face any delay in care once established.

Patient Experience Ratings: What Do Breast Surgery Patients Care About?

Introduction Patient experience is essential in the overall care; physicians often receive patient reviews evaluating their consultation encounters. Patient experience surveys can be a helpful tool to identify areas to target for improvement. We sought to evaluate what factors influenced breast surgery patients' reviews of their clinic visits. Methods Prospective surveys from 2018-2020 were reviewed from a single institution. Surveys were sent to all patients within 48 hours after visiting one of our breast surgery clinics, and patients were asked their preferred mode of contact for the survey. Patients responded to surveys with scores of 0-10, with 0 as "not likely" and 10 "extremely likely" to recommend the provider's office. Scores 0-6 were considered negative, 7-8 neutral, and 9-10 positive. Positive/Negative comments from patients were reviewed and classified according to mention of surgeon, clinic staff/team, clinic processing, and facility amenities. Results 744 out of 2205 patients contacted responded to the survey, resulting in a 33.7% response rate. Of this cohort, 47.6% (354/744) were new patients, and 52.4% (390/744) were established patients. Interactive voice response (IVR) and email, per patient indicated preferred mode of survey communication, had the highest responses. The average patient score was 9.5. Most ratings were positive (91.3%, 679/744), followed by neutral comments (5.2%, 39/744). There were 3.5% (26/744) which were negative ratings. Of those who responded, 47.7% (355/744) left a comment with their score. Surgeon-specific remarks were often noted in positive comments, followed by clinic staff/team comments. Negative comments most commonly referenced clinic processes. Conclusion Patient satisfaction surveys provide a window into creating the best patient experience. Further efforts to address these factors affecting patient experiences should be made to continue improving patient care.

Patient-Reported Outcome Measures of Breast Cancer Surgery: Evidence Review and Tool Adaptation.

The objective of this scoping review was to review survey instruments for Patient-Reported Outcome Measures (PROMs) and provide recommendations to construct a tool for PROMs specifically for breast cancer patients who have undergone surgery, to overcome the limitations of existing validated tools. A total of 924 articles were screened. Nine articles were selected based on the eligibility criteria. We found that PROMs' data collection along with advancements in the treatment of breast cancer and the resultant improved clinical outcomes, there is a growing appreciation and focus on improving patients' quality of life (QoL). Previous studies have shown that the assessment of PROMs is linked to a positive effect on patients' symptoms of distress, quality of life, acceptance, and satisfaction. Several PROMs tools have been validated for use in cancer survivors. However, it is unclear whether existing tools are appropriate for use in breast cancer patients who have undergone surgical treatment. Hence, we conducted a scoping review. Following a review of the current PROM related to breast cancer and the necessity to build specialized PROMs related to the outcomes of breast cancer surgery, we provide recommendations for the development of a comprehensive tool to overcome the limitations of existing PROMs tools.

Clinical subtype, treatment response, and survival in De Novo and recurrent metastatic breast cancer.

PURPOSE: This study evaluated whether patients with de novo metastatic breast cancer (MBC) have superior outcomes compared to those with recurrent MBC in a contemporary treatment era and examined factors related to outcome differentials. METHODS: Using an institutional database, we examined patient and tumor characteristics, treatment response, and outcome among 232 patients with de novo and 612 patients with recurrent MBC diagnosed between 2011 and 2017. RESULTS: De novo MBC had 9-month (m) longer overall survival (OS) than recurrent MBC (36.4 vs 27.4 m, p < 0.001). Contributions to this difference included nearly twofold more HER2-positive (29.3% vs 15.2%) and significantly fewer triple-negative breast cancers (20.3% vs 32.4%, both p < 0.001) in de novo compared with recurrent MBC cohorts. Stratified by clinical subtype, progression-free survival (PFS) on first-line therapy was significantly longer in de novo MBC in all but the triple-negative subtype, 25.5 vs 11.6 m (p < 0.001) among 390 patients with hormone receptor-positive, HER2-negative, 11.4 vs 5.4 m (p = 0.002) among 142 patients with HER2-positive, and 4.0 vs 3.0 m (p = 0.121) among 162 with triple-negative MBC. In multivariable analysis, de novo status remained independently associated with improved OS (hazard ratio 0.63, 95% CI 0.49-0.80), regardless of subtype and other features. CONCLUSION: Patients with de novo MBC have better outcomes than those with recurrent MBC. Differences in clinical subtype and response to therapy in the metastatic setting contribute to, but do not fully explain, this difference. Longer PFS to first-line therapy in de novo MBC suggests biologic differences compared to recurrent MBC, which may be intrinsic or due to acquired resistance from treatment for prior localized breast cancer in recurrent disease.

Radio-Frequency Identifier Devices (RFIDs): Our Experience With Wireless Localisation in Non-palpable Breast Masses at a UK Tertiary Breast Imaging Unit.

The aim of this report is to evaluate the impact of the percutaneous ultrasound-guided placement of wireless radio-frequency identifier devices (RFIDs; Hologic LOCalizer, Marlborough, Massachusett) and its impact in our practice of preoperative localisation of biopsy-proven breast cancers, post-vacuum assisted biopsy-site hematoma, and lymph nodes for targeted dissection pre-operatively. A single institutional retrospective analysis of RFID usage for preoperative localisation in screening and symptomatic patients with non-palpable biopsy-proven breast carcinoma was reviewed from the radiology information system at our tertiary breast imaging unit. Its impact on the radiological and surgical team practice was reviewed, including the number of appointments, the interval between scheduling image-guided localisation and intraoperative localisation, procedure failure, average deployment, and surgical time. Feedback from surgeons and pathologists practice was also taken into consideration. Fifty-nine RFID clips were placed for wireless localisation of breast cancers, lymph nodes, and post-vacuum-assisted biopsy hematoma over nine months. Seventy-three per cent (73%; n=43/59) of RFID devices were placed in biopsy-proven carcinomas under direct ultrasound guidance. The learning curve was small, as the delivery system was similar to the commonly used localisation clips. The pilot process involved RFID with radioisotope injections for the breast mass for the initial 28% (n=12 /43) cases, which were gradually transitioned into RFID only. Radioisotope was used for sentinel node purposes if required. For targeted node dissection, 3% (n=2/59) patients received RFID for biopsy-proven metastatic node localisation, with one of two with adjunct radioisotope injection. Post-vacuum-assisted biopsy (VAB) hematoma was localised in 24% (n=14/59) cases, four of which received adjunct radioisotope in the pilot phase. The average procedure time for RFID deployment was five minutes. The average time for surgery was 20 minutes. 1.6% (n=1/59) incidence of RFID slipping from the surface of the site through surgical exposure attributed to the superficial and immediate pre-operative placement of the RFID. This was salvageable with adjunct radioisotope injection within the pilot phase. There were no incidences of repeat localisation or repeat exploration surgeries. Planned pre-operative localisation with RFID allows for better planning and less pressured service delivery and a success rate of 98-99%. This ultimately avoids lost theatre time and patient demotivation. Surgeons have reported excellent intra-operative detectability in their approach. There has been no difficulty in the detection of the RFID within the surgical cavity despite hematoma. RFID localisers are expensive compared to our usual practice of radioisotope injection but this can be recuperated through uncoupled tariffs like gain in slots of one-stop clinics, flexibility for placement, and avoiding lost theatre time, as these can be placed up to 30 days before surgery.

Genetic Polymorphisms as Predictors of Survival in Breast Cancer: Future Lessons in Historical Data.

Introduction Breast cancer is the most common cancer among women worldwide and one of the main causes of death in the female sex. Genetic polymorphisms in the mu-opioid receptor (OPRM1) and catechol-o-methyltransferase (COMT) genes have been shown to increase breast cancer risk. Variants in these genes may carry a prognostic impact in breast cancer. Long follow-up intervals are critical to adequately analyze prognosis in diseases with prolonged survival times and late relapses. Objective To analyze the impact of genetic polymorphisms on the survival of a cohort of breast cancer patients with very long follow-up. Methods This was a retrospective study of patients treated at Portuguese Oncology Institute of Porto (IPO Porto), a Portuguese comprehensive cancer center, with invasive carcinoma of the breast with very long follow-up, with analysis of genetic polymorphisms OPMR1 rs1799971 (AA vs. G allele) and COMT rs4680 (CC vs T allele) on biological samples. Statistical analysis of survival was performed using the Kaplan-Meier method, log-rank test, and Cox regression method. Results A total of 143 patients with invasive breast cancer were included, with a median follow-up of 21.5 years. There was a statistically significant difference in overall survival (OS) at 30 years according to the OPMR1 polymorphism, with lower survival in patients with the AA genotype (p<0.05). The difference in OS according to the COMT polymorphism was also statistically significant, with worse survival in patients with genotype T allele (p<0.05). The genetic variants were not associated with patient age, stage at diagnosis, or tumor grade. Discussion The genetic polymorphisms of OPRM1 and COMT affected the overall survival of breast cancer patients, in concordance with previous research. Further investigation is needed in order to clarify the prognostic impact of these genetic alterations on breast cancer.
