RESUMEN

BACKGROUND: This study aims to determine the role of patient expectations as potentially modifiable factor of side-effects, quality of life, and adherence to endocrine treatment of breast cancer. PATIENTS AND METHODS: A 2-year prospective clinical cohort study was conducted in routine primary care with postoperative patients with hormone-receptor-positive breast cancer, scheduled to start adjuvant endocrine treatment. Structured patient-reported assessments of side-effects, side-effect expectations, quality of life, and adherence took place during the first week post-surgery and after 3 and 24 months of endocrine treatment. RESULTS: Of 111 enrolled patients, at 3 and 24 months, 107 and 88 patients, respectively, were assessed. After 2 years of endocrine treatment, patients reported high rates of side-effects (arthralgia: 71.3%, weight gain: 53.4%, hot flashes: 46.5%), including symptoms not directly attributable to the medication (breathing problems: 28.1%, dizziness: 25.6%). Pre-treatment expectations significantly predicted patient-reported long-term side-effects and quality of life in multivariate models controlling for relevant medical and psychological variables. Relative risk of side-effects after 2 years of endocrine treatment was higher in patients with high negative expectations at baseline than in those with low negative expectations (RR = 1.833, CI 95%, 1.032-3.256). A significant interaction confirmed this expectation effect to be particularly evident in patients with high side-effects at 3 months. Furthermore, baseline expectations were associated with adherence at 24 months (r = -0.25, P = 0.006). CONCLUSIONS: Expectations are a genuine factor of clinical outcome from endocrine treatment for breast cancer. Negative expectations increase the risk of treatment-specific side-effects, nocebo side-effects, and non-adherence. Yet, controlled studies are needed to analyze potential causal relationships. Optimizing individual expectations might be a promising strategy to improve side-effect burden, quality of life, and adherence during longer-term drug intake.

RESUMEN

Bisphosphonates have been studied in randomised trials in early breast cancer to investigate their ability to prevent cancer treatment-induced bone loss (CTIBL) and reduce the risk of disease recurrence and metastasis. Treatment benefits have been reported but bisphosphonates do not currently have regulatory approval for either of these potential indications. This consensus paper provides a review of the evidence and offers guidance to breast cancer clinicians on the use of bisphosphonates in early breast cancer. Using the nominal group methodology for consensus, a systematic review of the literature was augmented by a workshop held in October 2014 for breast cancer and bone specialists to present and debate the available pre-clinical and clinical evidence for the use of adjuvant bisphosphonates. This was followed by a questionnaire to all members of the writing committee to identify areas of consensus. The panel recommended that bisphosphonates should be considered as part of routine clinical practice for the prevention of CTIBL in all patients with a T score of <-2.0 or ≥2 clinical risk factors for fracture. Compelling evidence from a meta-analysis of trial data of >18,000 patients supports clinically significant benefits of bisphosphonates on the development of bone metastases and breast cancer mortality in post-menopausal women or those receiving ovarian suppression therapy. Therefore, the panel recommends that bisphosphonates (either intravenous zoledronic acid or oral clodronate) are considered as part of the adjuvant breast cancer treatment in this population and the potential benefits and risks discussed with relevant patients.

RESUMEN

UNLABELLED: Changes in bone mineral density (BMD) and trabecular bone score (TBS) were assessed in 70 patients who received either zoledronate (ZOL) (n = 34) or placebo (n = 36) for 2 years. In premenopausal women with breast cancer treatment-induced bone loss, 24 months of intravenous ZOL treatment significantly increased the lumbar spine BMD and the TBS. INTRODUCTION: The aim of this study was to compare the effects of 4 mg intravenous zoledronate (ZOL) versus placebo (PLB), every 3 months, on the lumbar spine (LS) bone mineral density (BMD) and the trabecular bone score (TBS) in premenopausal women with breast cancer (BC) treatment-induced bone loss. The TBS is a gray-level texture measurement which is related to the bone microarchitecture and considered to be independent of the BMD. METHODS: Changes in BMD and TBS were assessed in 70 patients who were recruited in the double-blind, placebo-controlled ProBONE-II trial and randomized to receive either ZOL (n = 34) or PLB (n = 36) for 2 years. The changes were assessed at baseline and at 12 and 24 months after treatment initiation. RESULTS: Patients receiving ZOL showed a mean increase in LS BMD from the baseline to 12 (2.17%) and 24 months (3.14%) of treatment and a mean increase in the TBS of 2.41 and 0.75%, respectively. Conversely, patients receiving PLB showed a mean decrease in the LS BMD from the baseline to 12 (-5.02%) and 24 (-6.43%) months and a mean decrease of -0.52 and -2.16% in the TBS, respectively. Changes in the BMD and the TBS from the baseline to 12 and 24 months were all significantly different for ZOL compared to PLB (p < 0.005). Furthermore, BMD and TBS showed a moderate correlation ranging from 0.28 (p = 0.087) to 0.47 (p = 0.003). CONCLUSIONS: In premenopausal women with BC, 24 months of intravenous ZOL treatment significantly increased the LS BMD as well as the TBS.

RESUMEN

OBJECTIVES: Many women are reluctant to undergo estrogen replacement therapy (ERT) and discontinue the treatment within 12 months. The aim of this study was to investigate the persistence rates of ERT in hysterectomized women over the past decade, reflecting changes in the post-Women's Health Initiative (WHI) era. METHODS: We analyzed 8045 patients receiving ERT from 2004 to 2013 using the Disease Analyzer database. RESULTS: After 12 months of follow-up, only 24.6% of patients receiving 1 mg and 24.5% of patients receiving 2 mg of oral ERT were still on treatment (p < 0.0001). The persistency rate of patients receiving <50 µg of transdermal ERT was 28.6% compared to 33.5% for patients receiving >50 µg within the 12 months of follow-up. ERT that began in 2007-2009 was associated with a higher discontinuation rate (hazard ratio 1.06, p = 0.0660) than ERT that began in 2010-2013 (hazard ratio 0.88, p = 0.0001). CONCLUSIONS: Our results indicate low persistency rates in women on ERT irrespective of the dose as well as the route of administration. However, a decrease in discontinuation rates was found when comparing women in the early vs. late post WHI era.

RESUMEN

OBJECTIVES: Dual-energy X-ray absorptiometry (DXA) is the gold standard for assessment of bone mineral density, an important risk factor for osteoporotic fractures. Recent reports suggest that quantitative ultrasonometry (QUS) is able to predict fractures; however, only limited data in women with hip fractures are available. METHODS: We examined 91 postmenopausal women who had sustained an osteoporosis-related hip fracture within the past 7 days using DXA and six different QUS devices and compared them with 91 healthy age-matched controls. RESULTS: Femoral neck (FN), total hip (TH) and lumbar spine (LS) T-scores were lower in women with hip fractures compared to matched controls: - 2.38 vs. - 1.64 (p < 0.001), - 2.36 vs. - 1.44 (p < 0.001) and - 2.05 vs. - 1.50 (p = 0.41), respectively. The T-scores of the Achilles, Sahara, InSight and Omnisence QUS devices were also lower in patients with hip fractures compared to matched controls: - 3.20 vs. - 2.36 (p < 0.001), - 2.196 vs. - 1.761 (p = 0.005), - 2.631 vs. - 1.849 (p < 0.001), - 3.707 vs. - 3.030 (p = 0.032), respectively. However, the T-scores of the DBM and QUS-2 did not differ between the two groups: - 4.543 vs. - 4.324 (p = 0.352) and - 1.7 vs. - 2.0 (p = 0.465), respectively. Compared to DXA (hip), the odds ratios of the Achilles, InSight and Sahara were comparable, while the odds ratios of the DBM, Omnisence and QUS-2 were significantly lower (p ≤ 0.05). CONCLUSIONS: Compared to DXA, the Achilles, Sahara and InSight QUS devices showed similar hip fracture discrimination while the DBM, Omnisence and QUS-2 did not. Therefore, some QUS devices are able to identify a clinically meaningful risk factor in women at high risk of hip fracture.

RESUMEN

OBJECTIVES: Many women are reluctant to take menopausal hormone therapy (MHT) and discontinue the treatment within 12 months. The aim of this study was to investigate the persistence rates of combined MHT in the last decade, reflecting changes in the post-Women's Health Initiative era. METHODS: We analyzed 17 020 patients receiving combined MHT from 2004 to 2013 using the Disease Analyzer database. RESULTS: After 12 months of follow-up, 44.6% and 33.5% of patients receiving 1 mg and 2 mg, respectively, of oral combined MHT were still on treatment (p < 0.0001). The persistence rate of patients receiving < 50 µg of transdermal MHT was 39.1% after 1 year of treatment and presented no differences compared to patients receiving ≥ 50 µg of transdermal MHT with a persistence rate of 38.2%. MHT start in the years 2007-2009 was associated with higher discontinuation rates (hazard ratio 1.04, p = 0.0709) than MHT start in the years 2010-2013 (hazard ratio 0.90, p = 0.0001). CONCLUSIONS: Our results indicate that patients beginning their treatments in the years 2010-2013 were more treatment-persistent than patients beginning with MHT in the early years after publication of the Women's Health Initiative study (2004-2009). Administration of low-dose oral MHT and transdermal MHT is associated with increased persistency compared to higher doses of oral MHT.

RESUMEN

OBJECTIVES: The aim of this study was to investigate the influence of anastrozole on serum hormone levels in postmenopausal women with hormone receptor-positive breast cancer. METHODS: We prospectively determined serum levels of estradiol, testosterone, dehydroepiandrosterone sulfate (DHEAS), sex hormone binding globulin (SHBG), follicle stimulating hormone (FSH) and luteinizing hormone (LH) at screening, as well as after 12 and 24 months of treatment and studied the associations with markers of bone turnover and bone mineral density (BMD). RESULTS: Altogether, a full set of hormone levels was available for 70 patients. Anastrozole treatment led to decreases of 92.1% for estradiol and 11.1% for LH over the observation period (p < 0.001). Conversely, FSH, DHEAS and testosterone concentrations increased by 5.9%, 33.3% and 50%, respectively (p < 0.001). SHBG levels remained stable during the 24 months of treatment (p = 0.355). There were modest associations between FSH, SHBG, CrossLaps and N-terminal propeptide of human procollagen type I (p < 0.05). Moreover, SHBG correlated positively with the BMD of femoral neck, total hip, total hip T-score, lumbar spine and the lumbar spine T-score, whereas FSH and estradiol correlated with the lumbar spine T-score (p < 0.05). CONCLUSIONS: During the 24 months of follow-up, treatment with anastrozole decreased the serum levels of estradiol and LH. Furthermore, we found notable increases of serum levels of FSH, DHEAS and testosterone in the first 12 months of treatment, stabilizing thereafter. Additionally, we were able to correlate hormone levels with markers of bone turnover and BMD for the first time in this regard.

RESUMEN

UNLABELLED: This analysis investigated the persistence of teriparatide for treatment of osteoporosis in 829 patients according to gender and health care provider treated with teriparatide. This study showed that female patients were less persistent than males and those patients treated in the practices of orthopedic surgeons were more treatment persistent than patients treated in general practitioner (GP) practices. INTRODUCTION: The optimal persistency of teriparatide (TPTD) is of the upmost importance to ensure fracture risk reduction and pain relief. Data reporting on gender-specific or health care provider-dependent differences on health care provider-dependent persistence is currently lacking. METHODS: We analyzed a large dataset extracted from the Disease Analyzer database (IMS Health, Germany). Out of a dataset of 15 million patients, we identified patients with osteoporosis who received first-time teriparatide prescriptions from January 2005 to December 2012. RESULTS: All 829 patients (677 females and 152 males) were included in the study. The patients were treated by 214 general practitioners (GPs) and 143 orthopedic surgeons. After 18 months of follow-up, 39.5 % of the female and 34 % of the male patients discontinued their treatment (p = 0.0308). We found a significant difference in the discontinuation rate of patients treated by orthopedic surgeons (35.0 %) compared to patients treated by GPs (44.2 %) (p = 0.0445). Additionally, at the end of the 18 months of follow up, 39.4 % of female and 47.8 % of male patients were still on treatment. We found a highly significant decreased risk for treatment discontinuation in patients with fractures prior to treatment initiation compared to those without such fractures (hazard ratio (HR) 0.77; 95 % confidence interval (CI) 0.66-0.90). There was a significantly increased risk of treatment discontinuation for female patients (HR 1.38; 95 % CI 1.10-1.74) compared to male patients. CONCLUSIONS: In conclusion, female patients presented higher discontinuation rates of TPTD compared to males. Patients treated in the practices of orthopedic surgeons were more persistent than patients treated in GP practices. TPTD persistence in patients with osteoporosis is higher than with antiresorptives but is still suboptimal and needs to be improved to ensure fracture risk reductions comparable to randomized controlled trial (RCT) results.

RESUMEN

PURPOSE: Within the statutory health insurance (SHI) cancer early detection programme (KFU) an organised, population-based, quality-assured mammographic screening programme in Germany was initiated for women aged 50-69 years in 2004. The aim of the study was to evaluate uptake and first experiences of participants with this new screening approach and to evaluate the background of knowledge, attitudes and intention to address a needs-assessed communication strategy. MATERIALS AND METHODS: A representative, explorative survey within the female population was conducted in 10 federal states. A telephone survey of randomly selected 68,188 contacts was performed, 9,004 women gave informed consent to evaluate rates of invitation and uptake followed by a mailed questionnaire. Of these, 3,469 were returned and 3,226 were analysed. RESULTS: The invitation rate of the programme was 56.6%, the uptake of mammographic screening was 66%, and the screening coverage rate was 37.3%. 90% of the participants were insured by SHI, women with lower socio-economic strata were attracted in accordance with the data of the general population. 61% of all women did not know that the risk of breast cancer increases with age and 56% believed that screening prevents breast cancer. 62.1% judged their own risk to be low. A physician's recommendation to participate was significantly associated with attendance (p<0.05). 90% of the participants would follow the next invitation. CONCLUSION: The KFU targeted group of women was reached and the organised mammography screening programme was well perceived by invited women. For developing a lasting communication strategy information deficits have to be considered along with beliefs and attitudes of elegible women.

RESUMEN

Public health research depends on empirical information that is based on data of high quality. The aim of this study was to apply the current guidelines developed by the Technology and Methodology Platform for Networked Medical Research (TMF) for the independent assessment and enhancement of data quality. A clinical register of female breast cancer patients from two periods (N = 389 of 1996-1997 and N = 488 of 2003-2004) was used. To check the plausibility, organization, and correctness of the data quality levels, data quality indicators (DQI) were chosen, operationalized, and the variance ratios of normative-analytic-defined thresholds were calculated. Significant deviations led to data improvement, which included the commonly known source data verification (SDV). A summary data quality score was calculated before and after application of the guidelines. Eleven out of 24 DQIs were tested. Data quality systematically increased from 51.6 to 67.7%. The guidelines facilitate a systematic assessment and improvement of data quality with a reasonable use of resources. This target-oriented procedure allows for a high transparency of the available data quality, which is essential for health research.

RESUMEN

BACKGROUND: Breast cancer (BC) therapies can have negative effects on bone. Current guidelines recommend antiresorptive therapy based on bone mineral density (BMD), and emerging guidelines include both clinical risk factors and BMD to assess the overall fracture risk. A retrospective, case-controlled study based on current and emerging guidelines was conducted in women with newly diagnosed BC to identify those who were at increased fracture risk based on current and emerging guidelines. METHODS: Baseline characteristics, fracture risk factors, and lumbar-spine (LS) and total-hip BMD in women with BC (88 premenopausal and 402 postmenopausal) were assessed to determine who would receive bisphosphonate therapy based on current and emerging guidelines. RESULTS: Among patients with estrogen-receptor-positive (ER(+)) BC, 18.8% of premenopausal and 36.9% of postmenopausal women were osteopenic at LS. In the postmenopausal cohort, osteoporosis was more prevalent in patients with ER(+) vs ER(-) BC. Current guidelines identified 8.9% of patients as eligible for antiresorptive therapy, clinical risk factors alone identified 6.5%, and BMD plus clinical risk factors identified 28.6%. CONCLUSIONS: In addition to fracture risk factors present at BC diagnosis, cancer therapies leading to BMD loss further increase fracture risk. Evaluating both BMD and clinical risk factors may allow more effective identification of BC patients with elevated fracture risk.

RESUMEN

BACKGROUND: The level of adherence of various pharmacological therapies in chronic diseases varies, but is predominantly low. With tamoxifen (TAM), 23% and 50% nonadherence after 1 and 4 years have been reported. Day-to-day clinical observation suggests that adherence may even be lower with aromatase inhibitors, but limited data exist on the situation in daily clinical routine. The aim of this study was to evaluate the rate of adherent patients in a randomly selected sample of postmenopausal women with primary breast cancer, who had been assigned to an adjuvant endocrine treatment with TAM or anastrozole (ANA). MATERIALS AND METHODS: We investigated a random sample of 100 postmenopausal women with breast cancer (50 TAM and 50 ANA) who had received surgery for their primary breast cancer at our hospital in 2004/2005 and thereafter had been assigned to an adjuvant endocrine treatment. We evaluated the adherence rate with a detailed questionnaire and additionally carried out a retrospective prescription check of the hospital chart as well as calling the local physicians of our patients. A patient was counted as adherent with a self-reported tablet intake of 80% or more and if a medication possession ratio of 80% or more was achieved. RESULTS: Regarding the baseline characteristics, a significant difference in mean age was noticed in women on ANA versus TAM [65 (+/-3) and 72 (+/-3); P<0.001]. All women on TAM and ANA reported to be adherent (100%). After controlling for prescriptions, only 40 (80%) and 27 (69%) of the women on TAM and ANA were still classified as adherent (P<0.01 and P<0.01 versus self-report). We found no significant correlation of adherence to any baseline characteristics or side-effects in a logistic regression model. CONCLUSIONS: An important goal of any therapeutic intervention is to achieve comparable efficacy in routine clinical practice to that demonstrated in randomised clinical trials. However, a similar magnitude of adherence will be necessary in routine clinical practice to assure comparable clinical effects. Our results further support the data on suboptimal adherence of women with breast cancer on adjuvant TAM treatment. Here, we evaluated for the first time the patient reported and real-world adherence on adjuvant ANA and were able to show a similarly low adherence compared with TAM. More prospective studies are needed to increase our understanding of the underlying reasons for nonadherence in women with breast cancer.

RESUMEN

On 1 July 2009, the German Network for Health Services Research [Deutsches Netzwerk Versorgungsforschung e. V. (DNVF e. V.)] approved the Memorandum III "Methods for Health Services Research", supported by the member societies mentioned below and published in this journal (Gesundheitswesen 2009; 71: 505-510). The focus of this part of the Memorandum III "Methods for health services research" is on the questions and methods of organisational health services research. In a first step, we describe the central questions which are at the core of organisational health services research. In a second step, we describe the methodological standards and requirements with regard to a) sampling, b) measurement and c) research design. We present a phase model for complex intervention trials. This model allows to conduct high quality organisational health services research, to integrate different methods of social research and to show in which phase they are of special importance.

The updated 2008 German Guideline for Early Detection of Breast Cancer provides evidence-based and consensus-based recommendations of the knowledge gained by the German Society for Surgery and the German Society of Plastic, Aesthetic, and Reconstructive Surgeons together with 29 professional societies, associations, and nonmedical organizations. The guideline is meant to assist physicians, healthy women, and patients in medical decisions with recommendations regarding the diagnostic chain in early detection of breast cancer. In addition to these recommendations, the guideline also includes descriptions of quality assurance for resources, procedures, outcomes, and evaluation using a set of quality indicators. It updates the previous version from 2003. The guideline's recommendations are presented. They are described in detail in the full publication (in German) Geburtsh Frauenh 2008; 68:251-261. The long version of the Guideline, methods report, and evidence report are available on the internet at www.awmf-leitlinien.de (reg. no. 077/001) with free access.

RESUMEN

Metastases to cervical lymph nodes do not exclusively derive from malignancies of the head and neck area. In the literature the region where distant metastases of breast carcinomas to the neck occur is exclusively named "supraclavicular". The system established by head and neck surgeons regarding neck node topography allows interdisciplinary management of patients with cervical lymph node metastases from breast cancer. Twelve patients suffering from breast cancer who presented with cervical masses have been examined. Most lymph node metastases were found in the posterior triangle of the neck and at the caudo-jugular level, but some metastases were even found in the upper jugular levels. The results presented show that neck node metastases of breast cancer are located superiorly to the supraclavicular region in more than 50% of the cases. According to the AJCC Staging System for Breast Cancer metastases located in the supraclavicular fossa are assessed as loco-regional metastases (N3c). Lymph node metastases situated above the supraclavicular region are not mentioned, but should be considered as distant metastases. This important question remains unanswered and deserves clarification in the current classification of the AJCC Staging System for Breast Cancer.

RESUMEN

Studies from six regions of Germany (Aachen (W1), Dresden (E1), Jena (E2), Marburg (W2), Munich (W3), and Stuttgart (C1)) have been compared to verify and assess the quality of healthcare using breast cancer as an example. All of the data collection was carried out in comprehensive cancer centres and is population-based, with the exception of C1. Classic prognostic factors and the initial treatment of 8661 women with breast cancer, diagnosed between 1996 and 1998, were examined. Primary therapy, breast conserving therapy (BCT), and the use of subsequent local radiation and/or systemic therapy (chemotherapy or hormonal therapy) were analysed. BCT was performed on 39.3-57.7% of patients. By pT-category, the proportion of BCT in the six regions were as follows: for pTis between 37.8 and 64.3%, for pT1 between 51.7 and 71.5%, for pT2 between 25.9 and 51.1%, for pT3 between 0 and 13.1% and for pT4 between 0 and 15.2%. Multivariate analyses, adjusted for age and biological factors, showed a significant influence of the treating hospital on the mastectomy rate. The use of radiotherapy after BCT (80%) was quite homogeneous in the six regions. The application of radiotherapy after mastectomy, however, varied between 10.4 and 32.2%. In all regions, for premenopausal patients, the use of adjuvant systemic therapy almost reflected the St. Gallen-Consensus recommendations. In contrast, post-menopausal women with positive lymph nodes were not always treated according to these standards. In all regions, age had an influence on the administration of treatment: elderly breast cancer patients received less BCT, less radiotherapy and less adjuvant therapy than recommended in the St. Gallen-Consensus. Feedback of the results was made available to each hospital, providing a comparative summary of patient care that could be used by the participating hospitals for self-assessment and quality-control.

RESUMEN

The goal of the Guideline "Early Detection of Breast Cancer in Germany" is to assist physicians, healthy women, and patients in the decision-making process in favour of appropriate health care regarding early detection and diagnosis of breast cancer. The principle of early detection of breast cancer embraces the detection of non-invasive stages of breast cancer (UICC stage 0, carcinoma in situ), reducing the frequency of invasive breast cancer development, as well as the identification of breast cancer at an early stage (UICC stage I) having a chance of cure of more than 90%, as shown by a large number of trials. The Guideline summarized in the following paper is a precondition to establishing a nation-wide, comprehensive, quality-assurance program for the early detection and diagnosis of breast cancer. The resulting consequence should be a timely mortality reduction of breast cancer. The cure of early stage disease will additionally be achieved by less intensive treatment methods while largely maintaining the quality of life of breast cancer patients. Implementing the Guideline offers the possibility of a significant improvement in women's health care.

RESUMEN

Quality of life (QoL) can be assessed in an accurate, valid and reliable way by means of standardized QoL questionnaires and is an important endpoint in clinical trials today. The aim of this study is to implement quality of life as a diagnostic tool for problem-oriented follow-up care of cancer patients. This is done in the framework of an intervention study in the area of regional health care research using qualitative analysis and the methodological concept of barrier analysis. We developed the diagnostic tool by generating individual, graphic QoL profiles based on patients' responses to the EORTC QLQ-C30 and the corresponding disease-specific modules BR23 for breast cancer and CR38 for rectal cancer. The clinical application is investigated by assessing physicians' responses. The QoL profile is judged as a useful diagnostic tool by all participating physicians. It enables physicians to assess the QoL of the patient and incorporate the knowledge they gain in their daily practice. Especially in breast cancer follow-up care QoL profiles give added value to both patients and doctors. The next implementation steps have to extend the concept of QoL to larger groups of patients and physicians by overcoming the restraining factors as identified in the barrier analysis.

RESUMEN

OBJECTIVE: To investigate whether imprint cytology of core needle biopsy (CNB) specimens from breast lesions is a useful method of rapidly obtaining additional diagnostic information and potentially can be used to reduce the number of biopsies needed. STUDY DESIGN: Cytologic analysis was performed on 173 breast lesions and compared with their histopathologic diagnoses (143 malignant and 30 benign). For imprint cytology, one CNB specimen was rolled between two slides and stained with Diff-Quik and Papanicolaou stain. RESULTS: The diagnostic overall accuracy of Diff-Quik stain (Papanicolaou stain) was 95.4% (95.9%), with a sensitivity of 96.5% (97.2%), specificity of 90% (90%), positive predictive value of 97.8% (97.8%) and negative predictive value of 84.3% (87.0%). There was no statistically significant difference between the stains. Histopathologic analysis had an overall accuracy of 97.7%, with a sensitivity of 97.2%, specificity and positive predictive value of 100% and a negative predictive value of 88.2%. CONCLUSION: Imprint cytology of CNBs is a sensitive method of detecting malignancies in breast tumors. Diff-Quik is a rapid and reliable approach that can reduce the number of biopsies. Inadequate and suspicious cases should be evaluated based on complementary diagnostic procedures for breast lesions.
