Dataset for reporting of the invasive carcinoma of the breast: recommendations from the International Collaboration on Cancer Reporting (ICCR).

Current national or regional guidelines for the pathology reporting on invasive breast cancer differ in certain aspects, resulting in divergent reporting practice and a lack of comparability of data. Here we report on a new international dataset for the pathology reporting of resection specimens with invasive cancer of the breast. The dataset was produced under the auspices of the International Collaboration on Cancer Reporting (ICCR), a global alliance of major (inter-)national pathology and cancer organizations. The established ICCR process for dataset development was followed. An international expert panel consisting of breast pathologists, a surgeon, and an oncologist prepared a draft set of core and noncore data items based on a critical review and discussion of current evidence. Commentary was provided for each data item to explain the rationale for selecting it as a core or noncore element, its clinical relevance, and to highlight potential areas of disagreement or lack of evidence, in which case a consensus position was formulated. Following international public consultation, the document was finalized and ratified, and the dataset, which includes a synoptic reporting guide, was published on the ICCR website. This first international dataset for invasive cancer of the breast is intended to promote high-quality, standardized pathology reporting. Its widespread adoption will improve consistency of reporting, facilitate multidisciplinary communication, and enhance comparability of data, all of which will help to improve the management of invasive breast cancer patients.

Triple-Negative Breast Cancer in a Young 23-Year-Old Woman with BRCA Mutation A about A Case and Literature Review

Triple-negative breast cancer (estrogen receptor negative, progesterone receptor negative and HER2 negative) is a particularly high-risk breast cancer which does not receive specific therapy targeting these proteins. We report the case of a 23-year-old patient diagnosed with triple-negative breast cancer of the left breast with a family history of breast cancer and carrying a BRCA1 mutation. The classification of breast cancer based on genomic data is required to allow us to optimize therapies and improve the management of breast cancer patients.

Abstract PO1-13-12: Mechanistic Analysis and Potential Therapeutic Implications in Breast Cancer with Fibrotic Focus

Abstract A fibrotic focus (FF) is a scar-like region that forms in the center of carcinoma due to excessive tumor stroma formation. In our earlier studies, we found FF as an independent poor prognostic factor for breast cancers. However, the underlying mechanisms of how the presence of FF contributed to a poor prognosis are still unknown. To improve our understanding of FF in breast cancer, we have investigated genes associated with FF and their impacts on breast cancer prognosis. Analysis of data from The Cancer Genome Atlas Program (TCGA) indicated that Bone Morphogenetic Protein 8A (BMP8A) was significantly upregulated in breast cancers with FF. To further validate this finding, immunohistochemistry (IHC) on BMP8A was performed on a local cohort of breast cancers (N= 900). Of these samples, 147 (16.3%) were found to be BMP8A positive, and there was a significant association between the presence of FF and high expression of BMP8A (p-value=0.026). We also found that high expression of BMP8A was positively correlated with apocrine phenotype, necrosis, increased Ki67 expression, and triple-negative breast cancer subtype; and most of these are poor prognostic factors for breast cancer. Kaplan-Meier survival estimate analysis revealed that high expression of BMP8A was significantly associated with poor overall survival (p-value=0.035). Gene ontology (GO) analysis showed that "Extracellular matrix organization" was the prominent biological process associated with BMP8A. KEGG pathway analysis suggested that BMP8A was significantly related to "Protein digestion and absorption", "ECM-receptor interaction", and "Focal adhesion" pathways, further validating its correlation with stromal FF. In cellular studies using MCF7 and MDA-MB-231 cell lines, overexpression of BMP8A was found to enhance breast cancer cell proliferation, invasion, and migration. Similar tumor-promoting phenotypes were exhibited when stimulating the cell lines with recombinant human BMP8A. In conclusion, our findings suggested that BMP8A was associated with FF in breast cancer, contributing at least partly to the aggressive features of these cancers. Our findings also provided new insights into the precision treatment and diagnosis of breast cancer. Further exploration of BMP8A as a therapeutic target and prognostic factor may contribute to improved management of breast cancer patients. Citation Format: Canbin Fang, Julia Y. S. Tsang, Gary M.K.

Abstract PO2-02-02: BREAst Cancer Personalized NuTrition (BREACPNT): dietary intervention in HR+ breast cancer patients treated with endocrine therapy

Abstract BACKGROUND Breast cancer patients treated with adjuvant endocrine therapy commonly experience weight gain, which has been associated with low adherence to therapy and worse breast cancer prognosis. Dietary interventions are the first-line treatment for weight management in breast cancer patients and have beneficial results. Yet, the ability to maintain these outcomes requires further research. Here, we aimed to assess whether a personalized postprandial glucose targeting (PPT) diet is beneficial for weight management and metabolic health as compared with the recommended Mediterranean (MED) diet in this population. DESIGN AND METHODS BREACPNT is a phase-2 randomized trial in HR+ patients with breast cancer, treated with adjuvant endocrine therapy. We randomly assigned participants to follow a MED diet or a PPT diet for a 6-month dietary intervention and additional 6-month follow-up. The PPT diet is based on a machine-learning algorithm that integrates clinical and microbiome features to predict personal postprandial glucose responses (PPGRs). During the intervention, participants were monthly followed by a registered dietitian, they were additionally connected to a 2-week continuous glucose monitoring (CGM) on 3-timepoints, provided stool and blood samples and self-reported dietary intake using a smartphone application. RESULTS Among 127 randomized patients (mean ± SD age 53 ± 10 years, BMI 28.6 ± 5 kg/m2), 103 (81%) completed the 6-month intervention period. A total of 94 participants provided 12-month follow-up data. Both interventions led to a significant weight loss. The PPT-diet showed numerically greater weight loss with median change of -1.45kg (IQR -3.75 – 0) compared to the MED-diet with median change of -1kg (IQR -3.2 - 0.1) , however this was not significant (p=0.9). Notably, at the 12-month time point , participants in the PPT arm were more likely to maintain the weight loss (median -1.2kg, IQR -4 - 0.1) compared to participants in the MED-arm (median -0.15kg , IQR -4.25 - 1.5), p=0.14) and had significantly improved waist circumference (median, IQR; -5 cm, -8-(-2) in the PPT arm, compared to -1cm, -6.5-3 in the MED arm, p=0.01). In terms of glucose metabolism the PPT-diet led to improved glycemic control as measured by CGM, with significant lower average postprandial glucose responses (PPGRs) and glucose coefficient of variation (CV) compared to the MED-diet arm (mean 6-month change in PPGR was 2.1 ± 7.5 mg/dL × h for MED and −3.4 ± 5.6 mg/dL × h for PPT, p< 0.001, and the 6-month mean change for CV was 0.15 ± 2.76 for MED and −1.37 ± 3.2 for PPT, p< 0.01). Within the entire cohort, participants who experienced the greatest weight loss (upper quartile) were more likely to be postmenopausal compared to participants in the lower quartile. Additionally, participants who did not achieve weight loss (lower quartile) were significantly more likely to be treated with tamoxifen than AI (p=0.015). CONCLUSIONS In this dietary intervention in HR+ breast cancer patients, both PPT diet and MED diet led to weight loss and improved food quality, with a slight advantage to PPT diet. PPT diet additionally improved glycemic features as compared to MED diet, which are linked to lower risk of obesity and disease recurrence, suggesting an advantage in a glucose targeting approach. Premenopausal and Tamoxifen treated patients were less likely to lose weight through the intervention. These findings may have implications for dietary advice in clinical practice.

Abstract PO1-28-03: Impact of the Oncotype DX® test over time and association with clinicopathological characteristics of Peruvian patients with early breast cancer: Experience in the last 15 years

Abstract Introduction: Gene expression assays provide prognostic and therapy-predictive information that complements management of early breast cancer patients. Oncotype DX® had showed prognostic and prediction of adjuvant chemotherapy benefit. The present study evaluates the impact of Oncotype DX® on therapeutic decision-making for 15 years and explores the association of clinicopathological characteristics with the Recurrence Score (RS) in Peruvian patients with early breast cancer. Material and methods: A retrospective multicenter analysis of 759 breast cancer patients treated in three oncological centers in Lima-Peru (Instituto Nacional de Enfermedades Neoplásicas, Oncosalud and Ricardo Palma) between 2007 and 2022 was conducted. Risk groups were classified according to Oncotype DX® result and menopausal status. For premenopausal women ≤ 50 years: low (RS=0-20), intermediate (RS=21-25) and high-risk (RS=26-100). A descriptive analysis was evaluated to observe the trend and profile of the patients who used the Oncotype test in 5 time periods (2007-2009, 2010-2013, 2014-2016, 2017-2019, 2020-2022). Subsequently, chi-square, t-test, analysis of variance and Poisson linear regression tests were applied to compare clinicopathological features with RS. Finally, univariate and multivariate analyses were performed using Cox logistic regression to identify the probability of association with the high-risk group. Results: 642 patients were included, 78.5% were postmenopausal, and 64.2% had clinical stage (CS) I. Overall, 63.4% had no recommendation for chemotherapy and only 5.6% had recurrence. 74.8% were classified as low-risk according to the Oncotype DX® result. Postmenopausal patients had negative lymph nodes (95.4%), the majority had undergone conservative surgery (71.8%) and had a low rate of breast reconstruction (11.9%). An increase in the use of Oncotype DX® was observed over time, especially in premenopausal patients (from 4.5% in 2007 to 36.9% in 2022). A significant association was found between luminal B subtype (p < 0.0001), histological grade 3 (p < 0.0001) and T3 vs. T1/2 (p=0.025). In univariate analysis, luminal B subtype (vs. luminal A, OR=5.56, 95% CI, 2.80-12.3, p< 0.001), T3 (vs. T1/2, OR=2.84, 95% CI, 0.13-30.0, p=0.006), histological grade 3 (vs. 1/2, OR=13.1, 95% CI, 5.35-39.6, p< 0.001) and histology (other vs. ductal/lobulillar/mucinous, OR=2.94, 95% CI, 0.57-13.5, p=0.003) provided a higher probability of obtaining a high-risk RS result. Similar results were found in multivariate analysis. Conclusion: The use of the Oncotype DX® had a significant impact on therapeutic decision-making in Peruvian patients with early breast cancer, with an increase of use in the last 15 years. A high-risk RS was associated with luminal B subtype, histological grade 3 and T3 tumor size, which could facilitate risk stratification and provide valuable information for the need of adjuvant chemotherapy.

Staff radiation doses during Sentinel Lymph Node procedure of breast cancer from injection to surgeon

The Sentinel Lymph Node (SLN) or Sentinel Lymph Node Biopsy (SLNB) technique involves various professionals from different departments in clinical settings to manage breast cancer patients properly. Tracing the nodular involvement of breast cancer patients requires radiation source Tc99m labeled with colloidal albumin to be injected at the tumor site. The patient becomes a radiation source for a sufficient time, which concerns the Nuclear Medicine (NM) and surgical staff. The study aims to provide the radiation doses of staff in the NM department during the SLN scintigraphy procedure and obtain an empirical model for calculating the radiation doses to staff in the surgical department from that particular patient. Radiation doses in SLN technique for breast cancer patients are minimal, and a sufficient number of SLN biopsy procedures can be performed by hospital staff within the category of non-radiation workers.

The impact of the COVID-19 pandemic on symptomatic breast cancer presentations in an Irish breast cancer unit: a retrospective cohort study.

The coronavirus-19 (COVID-19) pandemic caused delays in the diagnosis and management of breast cancer which may have affected disease presentation. The aim of this study was to compare rates of metastatic disease, tumour characteristics and management in breast cancer patients diagnosed before and after the onset of COVID-19. A retrospective chart review was conducted on patients in a university teaching hospital who were diagnosed with invasive symptomatic breast cancer in 2019 (prepandemic control group) and in 2020, 2021, and 2022 (pandemic study groups). Rates of new metastatic presentations, tumour histopathological characteristics, operation type, and therapies administered were statistically compared. A total of 1416 patients were identified. There was a significant increase in new metastatic breast cancer presentations in 2022 compared to 2019 (14.0% vs 3.8%, p ≤ 0.001), with non-significant increases in 2020 and 2021. Rates of adjuvant radiotherapy increased in 2020 and decreased in 2022 compared to 2019, with no significant change in neoadjuvant or adjuvant chemotherapy rates. Rates of axillary surgery increased during 2020 and 2021. There was an increase in high-grade tumours and lymphovascular invasion (LVI), and less frequent oestrogen receptor (ER) positivity in pandemic groups. No significant change was noted in BCS to mastectomy ratios, overall nodal positivity rates, or median tumour size. Symptomatic breast cancers diagnosed since the onset of COVID-19 demonstrated an increase in new metastatic presentations and more aggressive histopathological characteristics when compared to a pre-pandemic control group. Rates of adjuvant radiotherapy and axillary surgery increased during the pandemic.

Effectiveness of Cognitive Behavioral Therapy on Fear of Cancer Recurrence in Breast Cancer

Background Fear of cancer recurrence is one of the psychological distresses that seriously affects the quality of life of breast cancer patients. However, the evidence for cognitive behavioral therapy on fear of cancer recurrence in breast cancer is limited. Objective The aim of this study was to evaluate the effectiveness of cognitive behavioral therapy in reducing breast cancer patients’ fear of cancer recurrence. Methods Seven databases were searched for randomized controlled studies on cognitive behavioral therapy for fear of cancer recurrence in cancer patients from the inception of the database to April 30, 2023, with no language restrictions. Meta-analysis was performed using Stata MP 17. The Cochrane Risk of Bias Tool version 2 was used to assess the quality of the included studies. The quality of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation method. Results This review includes a total of 13 randomized controlled trials with 1447 breast cancer patients and survivors. When compared with controls, meta-analysis revealed that cognitive behavioral therapy significantly reduced the fear of cancer recurrence (g = −0.44; 95% confidence interval, −0.75 to −0.13; P < .001), whereas subgroup analysis revealed that only mindfulness-based cognitive therapy was significant. The overall risk of bias was high. The Grading of Recommendations, Assessment, Development and Evaluation assessment showed a low overall quality of evidence. Conclusions Cognitive behavioral therapy may be effective in reducing fear of cancer recurrence in breast cancer patients, and mindfulness-based cognitive therapy is particularly worthy of implementation. Implications for Practice Mindfulness-based cognitive therapy may be used as an additional strategy to help manage breast cancer patients’ fears of cancer recurrence.

Empowerment-Led Guided Self-Help Intervention for Symptom Burden in Breast Cancer Women Treated With Ovarian Function Suppression: A Randomized Trial Protocol.

Ovarian function suppression (OFS) treatment causes breast cancer patients' estrogens to fall rapidly to postmenopausal levels, and the 5-year treatment duration and 28-day treatment cycles place a heavy physical and psychological symptom burden on them, which in turn directly or indirectly affects the survival benefit. Managing symptom burden early in treatment is critical, but OFS-related studies have yet to be seen. Self-management is essential for patients' symptom burden. However, self-help management is hampered by patients' lack of knowledge, skills, motivation, etc. Guided self-help intervention (GSH) provides a feasible approach. Empowerment theory is a promising theoretical framework to guide self-management. A prospective two-arm parallel randomized controlled single-blind clinical trial will be conducted to investigate the effect of symptom burden GSH based on empowerment theory in breast cancer patients in the early stages of OFS treatment. A block randomization method is used to allocate 144 patients to either the control or intervention group. The program is conducted according to the OFS return-to-hospital treatment cycle. The intervention group will receive a total of two rounds and five sessions of empowering GSH, lasting at least 15 weeks in total; the control group will receive only usual nursing care. Symptom burden and related metrics will be assessed at baseline and 1, 3, and 6 months after OFS treatment, and changes between and within groups will be explored. This paper adhered to the SPIRIT and CONSORT guidelines. These results will help to validate the GSH in symptom burden management for breast cancer patients in OFS treatment early stages. It enriches its symptom burden management research and may provide implications for the whole cycle of OFS treatment patients.

Preventing Bone Loss in Breast Cancer Patients: Designing a Personalized Clinical Pathway in a Large-Volume Research Hospital.

We assess the impact of bone health clinical management in breast cancer (BC) patients receiving adjuvant endocrine therapy and design a personalized clinical pathway to reduce bone loss in an Italian research hospital. The primary endpoint was to assess (through the process improvement organizational method) the clinical pathway that post-surgical BC patients prescribed with endocrine therapy undergo to prevent bone loss. The secondary endpoint was to design a personalized clinical pathway for a prompt implementation of guidelines, to assess and possibly prescribe antiresorptive therapy. During the first year of the execution of the new Diagnostic Therapeutic Assistance Pathway, a 60% increase in Dual-Energy X-ray Absorptiometry evaluations within 30 days and a 39.5% increase in antiresorptive therapy prescription within 90 days (since the prescription of endocrine therapy) were shown, thus increasing patients' compliance. Case managers and bone health specialists in this context can improve patients' adherence to therapies and bone health, helping physicians to expand their collaboration.

The Canadian Breast Cancer Symposium 2023 Meeting Report

On 15–16 June 2023, healthcare professionals and breast cancer patients and advocates from across Canada met in Toronto, Ontario, for the 2023 Canadian Breast Cancer Symposium (CBSC). The CBSC is a national, multidisciplinary event that occurs every 2 years with the goal of developing a personalized approach to the management of breast cancer in Canada. Experts provided state-of-the-art information to help optimally manage breast cancer patients, including etiology, prevention, diagnosis, experimental biology, and therapy of breast cancer and premalignant breast disease. The symposium also had the objectives of increasing communication and collaboration among breast cancer healthcare providers nationwide and providing a comprehensive and real-life review of the many facets of breast cancer. The sessions covered the patient voice, the top breast cancer papers from different disciplines in 2022, artificial intelligence in breast cancer, systemic therapy updates, the management of central nervous system metastases, multidisciplinary management of ductal carcinoma in situ, special populations, optimization-based individual prognostic factors, toxicity management of novel therapeutics, survivorship, and updates in surgical oncology. The key takeaways of these sessions have been summarized in this conference report.

Abstract 4975: Stretching the boundary of Oncotype DX testing

Abstract Background: The predictive value of Oncotype DX in early-stage breast cancer had been well established. Strongest data support the use of chemotherapy for Recurrence Score (RS) > 30, with 25-30 deriving some benefit. Those with intermediate RS 16-25 are thought to have a small benefit from chemotherapy, especially premenopausal patients. Tumor size >5 cm is viewed as a high-risk feature regardless of RS. Our goal is to investigate how patients with uncertainty regarding their anticipated recurrence risk were managed at our institution. Methods: We conducted a retrospective analysis to explore the management of non-metastatic HER-2 negative hormone sensitive breast cancer patients diagnosed between 01/2018 &12/2020 stratifying them into the following study groups of interest: premenopausal (age <50), RS 16-25 compared to RS 26-30 and tumor size >5cm. Patients were compared based on whether they received adjuvant chemotherapy or not. The primary endpoint was the rate of local recurrence. Results: The results of our analysis are illustrated in the table. Studying the premenopausal group, 91.3% had RS < 16; yet 35% of them received chemotherapy. Patients with RS > 25 represented 3.2% of the premenopausal group, 12.5% of which did not receive chemotherapy. The six recurrences in the premenopausal group were all from the RS <16 subgroup. Comparing the RS 26-30 to the RS 16-25 group, patients were on average older with tumors being on average smaller, yet more patients were treated with chemotherapy; and there were no recurrences noted in both subgroups. Finally, in the tumor size >5 cm group, 91.4% had RS <16, almost all were premenopausal with many patients being lymph node negative, yet more than half received chemotherapy. Conclusions: In our study we demonstrate that in certain subgroups of early-stage breast cancer there is inconsistency in clinical practice when prescribing chemotherapy to patients factoring in their Oncotype DX scores. There is need for larger trials to guide clinicians on using Oncotype DX in those subgroups of patients. Characteristics, Treatment Pattern and Outcomes of Patient Groups of Interest Characteristics Premenopausal (N=506) RS 16-25 (N=28) RS 26-30 (N=36) Tumor Size >5 cm (N=47) Age, Mean (SD) 42.65 (5.46) 44.71 (3.85) 63.56 (9.65) 42.02 (6.14) Age, Range 19 - 49 36 - 49 45 - 79 28 - 57 Mean Tumor Size, mm (SD) 29.66 (52.21) 29.57 (33.88) 16.88 (11.19) 83.61 (37.52) Lymph Nodes Positive, n (%) 91 (18.0%) 2 (7.1%) 0 (0.0%) 16 (34.0%) Received Chemotherapy, n (%) 184 (36.4%) 7 (25.0%) 13 (36.1%) 25 (53.2%) Local Recurrence, n (%) 6 (1.2%) 0 (0.0%) 0 (0.0%) 0 (0.0%) Mean Follow- Up, months (SD) 19.28 (8.20) 19.39 (7.07) 21.21 (11.04) 19.26 (8.93) Citation Format: Zaid Al-Saheli, Vrushali Dabak.

Exploration of the relationship between tumor-infiltrating lymphocyte score and histological grade in breast cancer

BackgroundThe histological grade is an important factor in the prognosis of invasive breast cancer and is vital to accurately identify the histological grade and reclassify of Grade2 status in breast cancer patients.MethodsIn this study, data were collected from 556 invasive breast cancer patients, and then randomly divided into training cohort (n = 335) and validation cohort (n = 221). All patients were divided into actual low risk group (Grade1) and high risk group (Grade2/3) based on traditional histological grade, and tumor-infiltrating lymphocyte score (TILs-score) obtained from multiphoton images, and the TILs assessment method proposed by International Immuno-Oncology Biomarker Working Group (TILs-WG) were also used to differentiate between high risk group and low risk group of histological grade in patients with invasive breast cancer. Furthermore, TILs-score was used to reclassify Grade2 (G2) into G2 /Low risk and G2/High risk. The coefficients for each TILs in the training cohort were retrieved using ridge regression and TILs-score was created based on the coefficients of the three kinds of TILs.ResultsStatistical analysis shows that TILs-score is significantly correlated with histological grade, and is an independent predictor of histological grade (odds ratio [OR], 2.548; 95%CI, 1.648–3.941; P < 0.0001), but TILs-WG is not an independent predictive factor for grade (P > 0.05 in the univariate analysis). Moreover, the risk of G2/High risk group is higher than that of G2/Low risk group, and the survival rate of patients with G2/Low risk is similar to that of Grade1, while the survival rate of patients with G2/High risk is even worse than that of patients with G3.ConclusionOur results suggest that TILs-score can be used to predict the histological grade of breast cancer and potentially to guide the therapeutic management of breast cancer patients.

Comparison of music therapy and listening to the holy Quran in the management of breast cancer patients: A scoping review

Pain is one of the complaints that is often experienced by cancer patients due to treatment, cancer cell metastasis, or both. One of pain managements is using non-pharmacological therapy such as music therapy and murottal therapy or listening to the recitation of the holy Quran. This scoping review aims to compare music therapy and murottal therapy in pain management in breast cancer patients. The review methodology was used to map relevant evidence, synthesize findings, define keywords, and search for relevant articles from the EBSCO, Google Scholar, ProQuest, and PubMed databases. The next stage is selecting articles using PRISMA diagrams, data mapping, collecting, and summarizing findings. The results of the analysis revealed that music therapy provides a comfortable and relaxing effect. It is able to calm the soul, structured, and also universal, resulting in a decrease in pain intensity, while murottal therapy causes feelings of resignation and can cause respondents to think about the greatness of God making the respondents feel calmer, relaxed, and respond well. Music therapy can reduce 2 to 3 pain scales, while murottal therapy can reduce 4 pain scales. This proves that murottal therapy is more effective than music therapy.

Implications of Highly Penetrant Genetic Variants on Breast Surgery

It seems the most probable beneficiaries from the molecular era are those harboring hereditary genetic variants, which are responsible for 5% to 10% of all breast cancer diagnoses. There are several key implications of such variants on clinical practice, from expedited anticipation of primary cancer diagnoses, which can have their risk mitigated by risk reduction surgery, to pragmatism surrounding the management of male breast cancer patients. This communication discusses the implications of highly penetrant (or pathogenic) hereditary variants in contemporary breast surgery practice.

Water Extract Have Superior Cytotoxic Effect Than Ethanolic Extract of Clinacanthus Nutans Leaves in Breast Cancer Stem Cells.

The rapid development of medical technology in managing breast cancer patients still cannot solve the problem of recurrence and resistance. One of the causes of recurrence and molecular resistance is the presence of breast cancer stem cells (BCSCs). Clinacanthus nutans (C.nutans) is a plant found in Medan, North Sumatra, Indonesia. This plant is believed to have anticancer activity in community. Our study aimed to assess phytochemical of C.nutans leaves, isolate breast cancer stem cells and determine the cytotoxic effects of the ethanolic extract and water extract of C.nutans leaves on breast cancer stem cells at 24, 48, and 72 h of observation. We underwent the cytotoxic test by using MTT assay and isolated breast cancer stem cells by using MACS and validated them by mammosphere test. We found alkaloids, flavonoids, glycosides and tannins in simplicia and all extracts. BCSCs was valid with the diameter of the mammosphere BCSCs was > 60 μm. The IC50 values of 100%, 60%, 40%, 20% EE, and WE of C.nutans leaves were 227.30; 46.05; 31.12; 98.54, and 16.16 μg/ml respectively in the first 24 hours. In administering WE of C.nutans leaves, BCSCs viability was decreased at 24,48 and 72 hours of observation, namely 69.29±26%; 75.82 ± 21.02% and 38.94±9.34 % (p < 0.0001). The WE of C.nutans leaves had more substantial cytotoxic potential against BCSCs than the EE. The capability of WE C.nutans leaves to suppress BCSC's viability was time-dependent. The anticancer activity were believed originate from alkaloid and flavonoid group.

Pain associated with breast cancer: etiologies and therapies.

Pain associated with breast cancer is a prevalent problem that negatively affects quality of life. Breast cancer pain is not limited to the disease course itself but is also induced by current therapeutic strategies. This, combined with the increasing number of patients living with breast cancer, make pain management for breast cancer patients an increasingly important area of research. This narrative review presents a summary of pain associated with breast cancer, including pain related to the cancer disease process itself and pain associated with current therapeutic modalities including radiation, chemotherapy, immunotherapy, and surgery. Current pain management techniques, their limitations, and novel analgesic strategies are also discussed.

Development of a natural language processing model for deriving breast cancer quality indicators : A cross-sectional, multicenter study

ObjectivesMedico-administrative data are promising to automate the calculation of Healthcare Quality and Safety Indicators. Nevertheless, not all relevant indicators can be calculated with this data alone. Our feasibility study objective is to analyze 1) the availability of data sources; 2) the availability of each indicator elementary variables, and 3) to apply natural language processing to automatically retrieve such information. MethodWe performed a multicenter cross-sectional observational feasibility study on the clinical data warehouse of Assistance Publique – Hôpitaux de Paris (AP-HP). We studied the management of breast cancer patients treated at AP-HP between January 2019 and June 2021, and the quality indicators published by the European Society of Breast Cancer Specialist, using claims data from the Programme de Médicalisation du Système d'Information (PMSI) and pathology reports. For each indicator, we calculated the number (%) of patients for whom all necessary data sources were available, and the number (%) of patients for whom all elementary variables were available in the sources, and for whom the related HQSI was computable. To extract useful data from the free text reports, we developed and validated dedicated rule-based algorithms, whose performance metrics were assessed with recall, precision, and f1-score. ResultsOut of 5785 female patients diagnosed with a breast cancer (60.9 years, IQR [50.0–71.9]), 5,147 (89.0%) had procedures related to breast cancer recorded in the PMSI, and 3732 (72.5%) had at least one surgery. Out of the 34 key indicators, 9 could be calculated with the PMSI alone, and 6 others became so using the data from pathology reports. Ten elementary variables were needed to calculate the 6 indicators combining the PMSI and pathology reports. The necessary sources were available for 58.8% to 94.6% of patients, depending on the indicators.The extraction algorithms developed had an average accuracy of 76.5% (min-max [32.7%–93.3%]), an average precision of 77.7% [10.0%–97.4%] and an average sensitivity of 71.6% [2.8% to 100.0%]. Once these algorithms applied, the variables needed to calculate the indicators were extracted for 2% to 88% of patients, depending on the indicators. DiscussionThe availability of medical reports in the electronic health records, of the elementary variables within the reports, and the performance of the extraction algorithms limit the population for which the indicators can be calculated. ConclusionsThe automated calculation of quality indicators from electronic health records is a prospect that comes up against many practical obstacles.
