Violence against Women with Breast Neoplasms

The aim of this study is to assess the occurrence and type of violence suffered by women with breast cancer in the High Complexity Care Unit of a municipality in the South of Minas and patients in a support group of the University of the South of Minas Gerais. For that aim, a descriptive-exploratory methodology was applied through the quantitative method. Data were collected through a semi-structured form applied in individual interviews over a period of three months. We interviewed 57 patients and among those, 20 women （35.08%） reported having experienced some form of violence at some stage of their life, and the most frequently mentioned was the psychological violence followed by physical aggression. Although it was possible to identify that violence against affected these women, complaints against the aggressor were not affected.

The accuracy of magnetic resonance imaging and ultrasound in evaluating the size of early-stage breast neoplasms

Objective Breast cancer is the most frequently diagnosed cancer in women. Accurate evaluation of the size and extent of the tumor is crucial in selecting a suitable surgical method for patients with breast cancer. Both overestimation and underestimation have important adverse effects on patient care. This study aimed to evaluate the accuracy of breast magnetic resonance imaging(MRI) and ultrasound(US) examination for measuring the size and extent of early-stage breast neoplasms.Methods The longest diameter of breast tumors in patients with T_(1–2)N_(0–1)M_0 invasive breast cancer preparing for breast-conserving surgery(BCS) was measured preoperatively by using both MRI and US and their accuracy was compared with that of postoperative pathologic examination. If the diameter difference was within 2 mm, it was considered to be consistent with pathologic examination.Results A total of 36 patients were imaged using both MRI and US. The mean longest diameter of the tumors on MRI, US, and postoperative pathologic examination was 20.86 mm ± 4.09 mm(range: 11–27 mm), 16.14 mm ± 4.91 mm(range: 6–26 mm), and 18.36 mm ± 3.88 mm(range: 9–24 mm). US examination underestimated the size of the tumor compared to that determined using pathologic examination(t = 3.49, P < 0.01), while MRI overestimated it(t =-6.35, P < 0.01). The linear correlation coefficients between the image measurements and pathologic tumor size were r = 0.826(P < 0.01) for MRI and r = 0.645(P < 0.01) for US. The rate of consistency of MRI and US compared to that with pathologic examination was 88.89% and 80.65%, respectively, and there was no statistically significant difference between them(χ~2 = 0.80, P > 0.05).Conclusion MRI and US are both effective methods to assess the size of breast tumors, and they maintain good consistency with pathologic examination. MRI has a better correlation with pathology. However, we should be careful about the risk of inaccurate size estimation.

Breast cancer: Epidemiology, risk factors and screening

Breast cancer is a global health concern with a significant impact on the well-being of women. Worldwide, the past several decades have witnessed changes in the incidence and mortality of breast cancer. Additionally,epidemiological data reveal distinct geographic and demographic disparities globally. A range of modifiable and non-modifiable risk factors are established as being associated with an increased risk of developing breast cancer.This review discusses genetic, hormonal, behavioral, environmental, and breast-related risk factors. Screening plays a critical role in the effective management of breast cancer. Various screening modalities, including mammography,ultrasound, magnetic resonance imaging(MRI), and physical examination, have different applications, and a combination of these modalities is applied in practice. Current screening recommendations are based on factors including age and risk, with a significant emphasis on minimizing potential harms to achieve an optimal benefits-to-harms ratio. This review provides a comprehensive insight into the epidemiology, risk factors, and screening of breast cancer. Understanding these elements is crucial for improving breast cancer management and reducing its burden on affected individuals and healthcare systems.

Breast reconstruction:Review of current autologous and implantbased techniques and long-term oncologic outcome

Implant-based reconstruction is the most common method of breast reconstruction.Autologous breast reconstruction is an indispensable option for breast reconstruction demanding keen microsurgical skills and robust anatomical understanding.The reconstructive choice is made by the patient after a discussion with the plastic surgeon covering all the available options.Advantages and disadvantages of each technique along with long-term oncologic outcome are reviewed.

Adjuvant therapy for hormone receptor-positive breast cancer: Perspective from a survey on breast cancer physicians' acceptance of practice-changing data

A cross-sectional online survey was conducted.A high proportion of the Chinese breast cancer(BC)physician respondents(n=77)would prescribe extended adjuvant endocrine therapy(AET)with aromatase inhibitors(AI)beyond 5 years for postmenopausal females with BC,especially those with higher risk.Respondents with≥15 years of clinical experience were more likely to prescribe a longer duration of AET for low-risk patients.Half of the respondents considered intermittent letrozole as an acceptable option.Most respondents would prescribe adjuvant chemotherapy to genomic high-intermediate risk[Oncotype DX recurrence score(RS)21-25]females aged≤50 years regardless of the clinical risk classification.

Clinical Trial of Letrozole (femara) versus Aminoglutethimide in Postmenopausal Women with Advanced Breast Cancer

Objective： To compare the response and adverse reactions of aminoglutethimide with that of femara, an oral aromatase inhibitor, in postmenopausal women with advanced breast cancer. Methods： Fifty patients were randomly assigned to femara 2.5 mg once daily （n=26） or aminoglutethimide （n=24） 125 mg twice daily in the first week, 250 mg twice daily in the second week, 250 mg three times daily in the third week and 250 mg four times daily in the fourth week, 30 days for one cycle for both groups. Results： Overall objective response rate （complete＋partial） of 26.9% for femara was 12.5% higher than that of aminoglutethimide, but there was no significant difference （P=0.294）. The percentages of stable disease were 53.8% and 50.0% respectively in both treatment groups and that of progressive disease of two groups were 19.2% and 37.5%. There was no significant difference between two arms in the receptor status, disease-free intervals, sites of disease and stages of treatment. Femara-related adverse events were fatigue （15.4%）, anorexia （11.5%）, dizziness （7.7%）, nausea （3.8%） and somnolence （3.8%）. However, incidence of nausea （25.0%） and vomiting （16.7%） in aminoglutethimide group was obviously higher and severer than that in femara group （P=0.045 and P=0.046）. Compared to femara group, frequency in dizziness （25.0%）, fatigue （20.8%）, anorexia （16.7%）, somnolence （12.5%） and cutaneous pruritus （12.5%） was higher in aminoglutethimide group. Allergic rash occurred in aminoglutethimide group. Conclusion： Femara was more effective and well tolerated than aminoglutethimide with respect to side effects in the treatment of postmenopausal women with advanced breast cancer.

Early prediction of pathological outcomes to neoadjuvant chemotherapy in breast cancer patients using automated breast ultrasound

Objective： Early assessment of response to neoadjuvant chemotherapy （NAC） for breast cancer allows therapy to be individualized. The optimal assessment method has not been established. We investigated the accuracy of automated breast ultrasound （ABUS） to predict pathological outcomes after NAC. Methods： A total of 290 breast cancer patients were eligible for this study. Tumor response after 2 cycles of chemotherapy was assessed using the product change of two largest perpendicular diameters （PC） or the longest diameter change （LDC）. PC and LDC were analyzed on the axial and the coronal planes respectively. Receiver operating characteristic （ROC） curves were used to evaluate overall performance of the prediction methods. Youden＇s indexes were calculated to select the optimal cut-off value for each method. Sensitivity, specificity, positive and negative predictive values （PPV and NPV） and the area under the ROC curve （AUC） were calculated accordingly.Results： ypT0/is was achieved in 42 patients （14.5%） while ypT0 was achieved in 30 patients （10.3%） after NAC. All four prediction methods （PC on axial planes, LDC on axial planes, PC on coronal planes and LDC on coronal planes） displayed high AUCs （all〉0.82）, with the highest of 0.89 [95% confidence interval （95% CI）, 0.83-0.95] when mid-treatment ＆BUS was used to predict final pathological complete remission （pCR）. High sensitivities （85.7%-88.1%） were observed across all four prediction methods while high specificities （81.5%-85.1%） were observed in two methods used PC. The optimal cut-off values defined by our data replicate the WHO and the RECIST criteria. Lower AUCs were observed when mid-treatment ABUS was used to predict poor pathological outcomes. Conclusions：ABUS is a useful tool in early evaluation of pCR after NAC while less reliable when predicting poor pathological outcomes.

Combined molybdenum target X-ray and magnetic resonance imaging examinations improve breast cancer diagnostic efficacy

BACKGROUND Early-stage breast cancer patients often lack specific clinical manifestations,making diagnosis difficult.Molybdenum target X-ray and magnetic resonance imaging(MRI)examinations both have their own advantages.Thus,a combined examination methodology may improve early breast cancer diagnoses.AIM To explore the combined diagnostic efficacy of molybdenum target X-ray and MRI examinations in breast cancer.METHODS Patients diagnosed with breast cancer at our hospital from March 2019 to April 2021 were recruited,as were the same number of patients during the same period with benign breast tumors.Both groups underwent molybdenum target X-ray and MRI examinations,and diagnoses were given based on each exam.The single(i.e.,X-ray or MRI)and combined(i.e.,using both methods)diagnoses were counted,and the MRI-related examination parameters(e.g.,T-wave peak,peak and early enhancement rates,and apparent diffusion coefficient)were compared between the groups.RESULTS In total,63 breast cancer patients and 63 benign breast tumor patients were recruited.MRI detected 53 breast cancer cases and 61 benign breast tumor cases.Molybdenum target X-ray detected 50 breast cancer cases and 60 benign breast tumor cases.The combined methodology detected 61 breast cancer cases and 61 benign breast tumor cases.The sensitivity(96.83%)and accuracy(96.83%)of the combined methodology were higher than single-method MRI(84.13%and 90.48%,respectively)and molybdenum target X-ray(79.37%and 87.30%,respectively)(P<0.05).The combined methodology specificity(96.83%)did not differ from singlemethod MRI(96.83%)or molybdenum target X-ray(95.24%)(P>0.05).The Twave peak(169.43±32.05)and apparent diffusion coefficient(1.01±0.23)were lower in the breast cancer group than in the benign tumor group(228.86±46.51 and 1.41±0.35,respectively).However,the peak enhancement rate(1.08±0.24)and early enhancement rate(1.07±0.26)were significantly higher in the breast cancer group than in the benign tumor group(0.83±0.19 and 0.75±0.19,respectively)(P<0.05).CONCLUSION Combined molybdenum target X-ray and MRI examinations for diagnosing breast cancer improved the diagnostic sensitivity and accuracy,minimizing the missedand misdiagnoses risks and promoting timely treatment intervention.

A multicenter hospital-based diagnosis study of automated breast ultrasound system in detecting breast cancer among Chinese women

Objective： The automated breast ultrasound system（ABUS） is a potential method for breast cancer detection;however, its diagnostic performance remains unclear. We conducted a hospital-based multicenter diagnostic study to evaluate the clinical performance of the ABUS for breast cancer detection by comparing it to handheld ultrasound（HHUS） and mammography（MG）.Methods： Eligible participants underwent HHUS and ABUS testing; women aged 40–69 years additionally underwent MG. Images were interpreted using the Breast Imaging Reporting and Data System（BI-RADS）.Women in the BI-RADS categories 1–2 were considered negative. Women classified as BI-RADS 3 underwent magnetic resonance imaging to distinguish true-and false-negative results. Core aspiration or surgical biopsy was performed in women classified as BI-RADS 4–5, followed by a pathological diagnosis. Kappa values and agreement rates were calculated between ABUS, HHUS and MG.Results： A total of 1,973 women were included in the final analysis. Of these, 1,353（68.6%） and 620（31.4%）were classified as BI-RADS categories 1–3 and 4–5, respectively. In the older age group, the agreement rate and Kappa value between the ABUS and HHUS were 94.0% and 0.860（P〈0.001）, respectively; they were 89.2% and0.735（P〈0.001） between the ABUS and MG, respectively. Regarding consistency between imaging and pathology results, 78.6% of women classified as BI-RADS 4–5 based on the ABUS were diagnosed with precancerous lesions or cancer; which was 7.2% higher than that of women based on HHUS. For BI-RADS 1–2, the false-negative rates of the ABUS and HHUS were almost identical and were much lower than those of MG.Conclusions： We observed a good diagnostic reliability for the ABUS. Considering its performance for breast cancer detection in women with high-density breasts and its lower operator dependence, the ABUS is a promising option for breast cancer detection in China.

Exploring the employment readiness and return to work status of breast cancer patients and related factors

Objective:To investigate the employment status,employment readiness,and other factors affecting the ease or difficulty with which breast cancer patients effect their return to work(RTW).Methods:This study adopted a mixed-method design,recruiting participants from among breast cancer patients in a cancer hospital in Hunan from December 2018 to June 2019.We approached 300 individuals,192 of whom ultimately participated in this study.The quantitative part of the study involved several scales:the Patient Health Questionnaire-9(PHQ-9),the Brief Fatigue Inventory(BFI),the Work Ability Index(WAI),and the Lam Assessment of Employment Readiness(LASER).The qualitative part involved a set of open-ended questions and written responses collected from 41 participants who had already returned to work at the time of data collection.Their written responses mainly concerned factors influencing RTW.Results:Forty-one breast cancer patients had returned to work.The results reported a median total Cognitive Symptom Checklist score of 9.00(6.00,15.25),a median WAI score of 5.00(3.50,9.75),a median BFI score of 26.00(14.75,42.00),a median total PHQ-9 score of 8.00(5.25,17.00),and a LASER score of 50.35±11.90.Multiple regression analysis showed that the participants’cancer stage,cognitive limitations,depression,fatigue,and work ability were significant predictors of employment readiness(P<0.05).Exploring the qualitative data,we found that higher skill levels,better social support,and a flexible work schedule facilitated RTW;stress,lack of confidence in one’s work skills,depression,and fatigue are all possible barriers to RTW.Conclusion:The findings indicate that breast cancer patients have a low level of employment readiness.Nurses and other healthcare providers can develop relevant interventions to promote employment readiness and ultimately achieve RTW in this study population.

Effects of weight-lifting or resistance exercise on breast cancer-related lymphedema:A systematic review

The purpose of this systematic review was to identify the effects of weight-lifting or resistance exercise on breast cancer-related lymphedema.Published articles written in English were retrieved from electronic databases,including ScienceDirect,PubMed,Scopus,and CINAHL databases.Hand-searches for unpublished papers were also completed.Content analysis was used to examine articles that met the inclusion criteria.Among 525 searched papers,15 papers met the inclusion criteria:13 trials evaluated weight-lifting or resistance exercise alone and two trials evaluated weight-lifting or resistance exercise plus aerobic exercise.The results of the review showed that no arm volume change was observed for either exercise modality.In addition,six included studies showed that weight-lifting or resistance exercise did not cause lymphedema or adverse events in patients at risk of breast cancer-related lymphedema.For patients with breast cancer-related lymphedema,six studies reported that change of swelling outcome measures were not significantly different between the weight-lifting or resistance exercise group and the control group.However,three included studies reported that volume of arm was significantly more reduced in the weight-lifting or resistance exercise group than those in the control group.The findings suggest that supervised resistance exercise may be safe,feasible,and beneficial in patients with breast cancer-related lymphedema or at risk for breast cancer-related lymphedema.However,the limitation of small sample size implies that further research is needed to confirm these findings.

Serological Diagnosis of Liver Metastasis in Patients with Breast Cancer

Objective To diagnose and explore the serological diagnostic factors for liver metastasis in patients with breast cancer before symptoms occur. Methods A total of 430 female in-patients with breast cancer of stages 0 to IIIC who came to Tianjin Medical University Cancer Institute and Hospital from January 2003 to January 2004 were studied and followed up until May 2011. Serum levels of biochemical markers for tumor and liver were measured at the time of diagnosis. Results Liver metastasis was more likely to occur in patients with stage Ill cancer or c-erbB-2-positive expression. Alanine aminotransferase, aspartate aminotransferase, ~/-glutamyltransferase （GGT）, alkaline phosphatase, lactate dehvdrogenase （LDH）, and carbohydrate antigen 1153 （CA153） levels were significantly higher in patients with liver metastasis than those without liver metastasis. Diagnostic indices of LDH, GGT, and CA153 were 174 U/L, 32 U/L, and 26.48 Dg/L, respectively. The areas under the curves of LDH, GGT, and CEA were 0.795, 0.784, and 0.661, respectively, and sensitivities of parallel tests for LDH and CA153 and for GGT and CA153 were 88.6% and 85.7 %, respectively. The specificity of serial tests for both pairs of enzymes was 97.7%. Conclusions Tile sensitivity and specificity of combined tumor and biochemical markers could be used as indicators during screening for breast-liver metastasis.

Exercise for fatigue in breast cancer patients: An umbrella review of systematic reviews

Objective:To evaluate evidence from published systematic reviews about the effectiveness of exercise interventions on fatigue management in breast cancer patients.Methods:PubMed,Web of Science,the Cochrane Library,the Cumulative Index of Nursing and Allied Health(CINAHL),Embase databases,the China National Knowledge Infrastructure(CNKI),the Wanfang database,the China Biomedical Literature Database(CBM),and the VIP database were searched to identify relevant systematic reviews.The reviews which assessed exercise interventions on cancer-related fatigue(CRF)in breast cancer patients were included.Quality of evidence was evaluated by the Grade of Recommendation,Assessment,Development,and Evaluation(GRADE)tool.The Assessment of Multiple Systematic Reviews(AMSTAR)appraisal tool was used to evaluate the methodological quality of included systematic reviews.Results:Twenty-four systematic reviews met all the inclusion criteria.The overall mean score for AMSATR is 7.38 and ranged from 4 to 10 points.In addition,21 reviews arrived at positive conclusions,which exercises could reduce CRF,and 3 obtained that exercise does not affect fatigue.As for GRADE,8 of the reviews were graded as'moderate',2 of the studies were'very low',and the others were'low'.Conclusions:Aerobic and resistance exercise can be regarded as beneficial to CRF in breast cancer patients,and limited evidence exists that yoga had an effect on reducing fatigue.The quality of the current systematic review is still far from satisfactory.

Evaluation of menopausal status among breast cancer patients with chemotherapy-induced amenorrhea

Objective： In patients with chemotherapy-induced amenorrhea （CIA）, the menopausal status is ambiguous anddifficult to evaluate. This study aimed to establish a discriminative model to predict and classify the menopausalstatus of breast cancer patients with CIA.Methods： This is a single center hospital-based study from 2013 to 2016. The menopausal age distribution andaccumulated incidence rate of CIA are described. Multivariate models were adjusted for established and potentialconfounding factors including age, serum concentration of estradiol （E2） and follicle-stimulating hormone （FSH）,feeding, pregnancy, parity, abortions, and body mass index （BMI）. The odds ratio （OR） and 95% confidenceinterval （95% CI） of different risk factors were estimated.Results： A total of 1,796 breast cancer patients were included in this study, among whom, 1,175 （65.42%） werepremenopausal patients and 621 （34.58%） were post-menopause patients. Five hundred and fifty patients wereincluded in CIA analysis, and a cumulative CIA rate of 81.64% was found in them. Age （OR： 1.856, 95% CI：1.732-1.990）, serum concentration of E2 （OR： 0.976, 95% CI： 0.972-0.980） and FSH （OR： 1.060, 95% CI：1.053-i.066）, and menarche age （OR： 1.074, 95% CI： 1.009-1.144） were found to be associated with the patients＇menopausal status. According to multivariate analysis, the discriminative model to predict the menopausal status isLogit （P）=-28.396＋0.536Age-0.014E2＋0.031FSH. The sensitivities for this model were higher than 85%, and itsspecificities were higher than 89%.Conclusions： The discriminative model obtained from this study for predicting menstrual state is important forpremenopausal patients with CIA. This model has high specificity and sensitivity and should be prudently used.

Photodynamic Therapy for Gynecological Diseases and Breast Cancer

Photodynamic therapy （PDT） is a minimally invasive and promising new method in cancer treatment. Cytotoxic reactive oxygen species （ROS） are generated by the tissueqocalized non-toxic sensitizer upon illumination and in the presence of oxygen. Thus, selective destruction of a targeted tumor may be achieved. Compared with traditional cancer treatment, PDI has advantages including higher selectivity and lower rate of toxicity. The high degree of selectivity of the proposed method was applied to cancer diagnosis using fluorescence. This article reviews previous studies done on PDT treatment and photodetection of cervical intraepithelial neoplasia, vulvar intraepithelial neoplasia, ovarian and breast cancer, and PDT application in treating non-cancer lesions. The article also highlights the clinical responses to PDT, and discusses the possibility of enhancing treatment efficacy by combination with immunotherapy and targeted therapy.

PACLITAXEL PLUS CARBOPLATIN FOR WOMEN WITH ADVANCED BREAST CANCER

Objective To evaluate the efficacy and safety of combination chemotherapy with paclitaxel and carboplatin for advanced breast cancer (ABC). Methods From January 2001 to March 2006, 45 patients with ABC were treated with combination chemotherapy of paclitaxel and carboplatin. Patients received infusion of paclitaxel 175 mg/m2 on day 1 every 3 weeks or 75 mg/m2 on day 1, 8, 15 every 4 weeks. Carboplatin was administrated on day 2 with a dose of area under the time-concentration curve (AUC) being 5. Results The median number of cycles was 3 (range, 2-6). The overall response rate was 62.2%. Median time to progression was 7.0 months (95%CI:5.1-8.9). Median overall survival was 29.0 months (95%CI: 20.1-37.9). One year survival rate was 73.3%. Response rate for first line and second line treatment were 62.1% and 62.5%, respectively. No significant difference in response existed between visceral metastasis and soft tissue metastasis. The main side effects included nausea/vomiting, neurotoxicity, and hematologic toxicities. Grade Ⅲ to Ⅳ adverse events included nausea/vomiting in 2 cases (4.4%), leukopenia in 17 cases (37.8%), and alopecia in 6 cases (13.3%). Conclusion Combination of paclitaxel and carboplatin is active in treatment of ABC with an acceptable toxicity profile.

Male Breast Cancer:10-Year Experience at Mansoura University Hospital in Egypt

Objective Male breast cancer （MBC） is a rare disease representing less than 1% of all malignancies. The objective of the study is to report clinicopathological characteristics, treatment patterns, and outcomes of MBC in Mansoura University Hospital, Egypt. Methods This retrospective study focused on male breast cancer patients during 10 years （2000-2009）. The studied variables were data regarding general characteristics of patients, treatment modalities and survival. Results The series included 37 patients （0.8% of all breast cancer）. The median age was 57.7 years （range： 26-86 years）. The main clinical complaint was a mass beneath the areola ill 94.5% of the cases. Most patients had a locally advanced disease. 94.5% of tumors were invasive duct carcinomas. The treatment was essentially surgery in 91.8%, followed by adjuvant radiotherapy （in 89.2%）, hormonal therapy （in 56.7%） and chemotherapy （in 91.8%）. Follow-up period ranged from 6-115 months. Local recurrence occurred in 4 cases and metastasis in 11 cases. The 2-year and 5-year overall survival （OS） rates were 81.6% and 60.5%, respectively. The 2-year and 5-year disease-free survival （DFS） rates were 68.4%, and 52.6%, respectively. OS was not significantly affected by any of the studied parameters. Factors influencing DFS were： T stage （P=0.05）, positive lymph nodes （P=0.043）, metastasis （P=0.004）, and chemotherapy （1＇=0.046）. Conclusions MBC is a rare disease and often diagnosed at a locally advanced stage. The management of male and female breast carcinoma is identical. Future research for better understanding of this disease is needed to improve the management and prognosis of male breast cancer patients.

Treatment for triple-negative breast cancer

Triple-negative breast cancers (TNBCs) neither express estrogen receptor and progesterone receptor nor over- express human epidermal growth factor receptor-2. Because of the special molecular features, triple-negative breast cancer is not either sensitive to endocrine therapy or targeted therapy of trastuzumab. There has not been standard treatment regimen for triple-negative breast cancer yet and chemotherapy has still been the chief therapy currently. However, with the great progress of oncology and molecular biology, the understanding of the natural history, pathophysiology and molecular features of this disease has been greatly improved, and a growing number of novel and effective therapies and discoveries of new biological targets for this phenotype of breast cancers have been reported, which provide new insights into therapeutic strategies for the women suffering from it.
