Diagnostic Accuracy of Breast Medical Tactile Examiners (MTEs): A Prospective Pilot Study.

Background: The usefulness of clinical breast examination (CBE) in general and in breast cancer screening programs has been a matter of debate. This study investigated whether adding vision-impaired medical tactile examiners (MTEs) improves the predictiveness of CBE for suspicious lesions and analyzed the feasibility and acceptability of this approach.

Methods: The prospective study included 104 patients.

Prediction of pathological complete response and prognosis in patients with neoadjuvant treatment for triple-negative breast cancer.

Background: It has been reported that pathological complete response is an important surrogate marker for disease-free survival and overall survival in patients with triple-negative breast cancer. This study investigates predictors of the response to neoadjuvant platinum-based or anthracycline-based treatment, and of the prognosis, in patients with triple-negative breast cancer.

Methods: A total of 121 patients with triple-negative breast cancer received neoadjuvant treatment with either platinum or anthracycline between 2008 and 2013.

BRCA mutations and their influence on pathological complete response and prognosis in a clinical cohort of neoadjuvantly treated breast cancer patients.

Purpose: BRCA1/2 mutations influence the molecular characteristics and the effects of systemic treatment of breast cancer. This study investigates the impact of germline BRCA1/2 mutations on pathological complete response and prognosis in patients receiving neoadjuvant systemic chemotherapy.

Methods: Breast cancer patients were tested for a BRCA1/2 mutation in clinical routine work and were treated with anthracycline-based or platinum-based neoadjuvant chemotherapy between 1997 and 2015.

Relevance of health economics in breast cancer treatment - the view of certified breast centres and their patients.

Breast cancer centres - certified in accordance with the criteria of the German Cancer Association and the German Mastology Association - are established throughout Germany. Although the setting up of centres and the subsequent need for certification are associated with a marked increase in costs, initial data show positive effects on quality. Certified centres are cost-effective from the point of view of health economics - they lead to improved quality in processes and results without creating any increase in costs for the funding bodies.

Health utilities in gynecological oncology and mastology in Germany.

Background And Aims: Cost increases in the healthcare system are leading to a need to distribute financial resources in accordance with the value of each service performed. Health-economic decision-making models can support these decisions. Due to the previous unavailability of health utilities in Germany (scored states of health as a basis for calculating quality-adjusted life-years, QALYs) for women undergoing treatment, international data are often used for such models.

Comprehensive visualization of paresthesia in breast cancer survivors.

Purpose: As breast cancer survivors are benefiting increasingly from advanced forms of therapy, the side effects of locoregional treatment in the adjuvant setting are becoming more and more important. This article presents a new method of assessing the spatial distribution of paresthesia in breast cancer survivors after different locoregional treatments.

Methods: A structured questionnaire assessing paresthesia, with body pictograms for marking paresthesia areas, was completed by 343 breast cancer survivors.

Assessment of breast volume changes during human pregnancy using a three-dimensional surface assessment technique in the prospective CGATE study.

Pregnancies and breastfeeding are two important protective factors concerning breast cancer risk. Breast volume and breast volume changes might be a breast phenotype that could be monitored during pregnancy and breastfeeding without ionizing radiation or expensive equipment. The aim of the present study was to document changes in breast volume during pregnancy prospectively.

Shared decision-making in metastatic breast cancer: discrepancy between the expected prolongation of life and treatment efficacy between patients and physicians, and influencing factors.

Treatment decisions in oncology are based on a balance between the efficacy of therapy and its side effects. Patients with metastases and patients with a limited prognosis are a particular challenge, since communication about the disease situation and the expected therapeutic benefit is difficult not only for patients, but also for physicians. The aim of this study was therefore to compare the benefits expected of therapy by patients and physicians.

Prognostic relevance of Ki-67 in the primary tumor for survival after a diagnosis of distant metastasis.

Prediction of the prognosis for metastatic breast cancer patients depends on molecular subtypes similar to those found in patients with primary breast cancer. Several studies have shown that estrogen receptor (ER) and progesterone receptor (PR) status determine the course of the disease and the prognosis. As Ki-67 helps to differentiate molecular subtypes in patients with primary breast cancer, the aim of this study was to assess the prognostic relevance of Ki-67 in the primary tumor in relation to its prognostic relevance for patients with metastatic breast cancer.

Financing of certified centers: a willingness-to-pay analysis.

Introduction: Although care in certified breast centers is now established throughout Germany, numerous services are still not being reimbursed. This also affects other centers involved in the specialty of gynecology such as gynecological cancer centers, perinatal centers, and endometriosis centers. Although a certified center is entitled to charge additional fees, these are in most cases not reimbursed.

Factors influencing breast changes after pregnancy.

Pregnancy and breastfeeding are major factors reducing breast cancer (BC) risk. A potential mechanism for this effect might be changes in mammographic density, but other factors might be involved. The aim of this study was to investigate factors influencing changes in breast size and breast stiffness after pregnancy.

Shared decision-making in breast cancer: discrepancy between the treatment efficacy required by patients and by physicians.

Several factors can influence individual perceptions of the expected benefit of recommended adjuvant treatment for breast cancer. This study investigated differences between patients and physicians with regard to the required efficacy of treatment and the factors influencing patients' and physicians' willingness to accept different therapeutic options. A total of 9,000 questionnaires were distributed to patients with breast cancer, and 6,938 questionnaires were distributed to physicians treating breast cancer patients.

Circulating micro-RNAs as potential blood-based markers for early stage breast cancer detection.

Introduction: MicroRNAs (miRNAs, miRs) are a class of small, non-coding RNA molecules with relevance as regulators of gene expression thereby affecting crucial processes in cancer development. MiRNAs offer great potential as biomarkers for cancer detection due to their remarkable stability in blood and their characteristic expression in many different diseases. We investigated whether microarray-based miRNA profiling on whole blood could discriminate between early stage breast cancer patients and healthy controls.

Ki67, chemotherapy response, and prognosis in breast cancer patients receiving neoadjuvant treatment.

Background: The pathological complete response (pCR) after neoadjuvant chemotherapy is a surrogate marker for a favorable prognosis in breast cancer patients. Factors capable of predicting a pCR, such as the proliferation marker Ki67, may therefore help improve our understanding of the drug response and its effect on the prognosis. This study investigated the predictive and prognostic value of Ki67 in patients with invasive breast cancer receiving neoadjuvant treatment for breast cancer.

Quality assured health care in certified breast centers and improvement of the prognosis of breast cancer patients.

Background: Increasing effort has been put in the implementation and certification of breast centers in order to establish standardized, quality assured health care for breast cancer patients. The aim of this analysis was to investigate whether patients treated in certified breast centers (CBC) have a favorable prognosis as compared to patients treated outside of certified breast treatment units.

Patients And Methods: The data of 3,940 patients with invasive nonmetastatic breast cancer were analyzed with regard to differences in patient and tumor characteristics and crude overall survival according to diagnosis in or outside CBC in Middle Franconia, Germany.

Breast volumetry using a three-dimensional surface assessment technique.

Background: Breast volume is a relevant measure for the prevention and prediction of diseases and for aesthetic surgery. This study evaluated a new technique to determine breast volume and compared measures using a three-dimensional (3D) body surface scanner and magnetic resonance imaging (MRI) scans, with the latter used as the standard method.

Methods: Both MRI scans and body surface 3D scans were obtained from 22 women.

Assessment of breast cancer tumour size using six different methods.

Objectives: Tumour size estimates using mammography (MG), conventional ultrasound (US), compound imaging (CI) and real-time elastography (RTE) were compared with histopathological specimen sizes.

Methods: The largest diameters of 97 malignant breast lesions were measured. Two US and CI measurements were made: US1/CI1 (hypoechoic nucleus only) and US2/CI2 (hypoechoic nucleus plus hyperechoic halo).

Assessment of mammographic density before and after first full-term pregnancy.

Mammographic density (MD) has consistently been found as one of the strongest breast cancer risk factors. In our study, both qualitative and quantitative density measurements were performed in a hospital-based group of premenopausal women before and after first full-term pregnancy providing an opportunity for direct evaluation of the effects of one pregnancy on MD. Mammograms were obtained from 23 women before and after first full-term pregnancy and from 28 nulliparous controls.

Accelerated partial breast irradiation: 5-year results of the German-Austrian multicenter phase II trial using interstitial multicatheter brachytherapy alone after breast-conserving surgery.

Purpose: To evaluate the impact of accelerated partial breast irradiation on local control, side effects, and cosmesis using multicatheter interstitial brachytherapy as the sole method for the adjuvant local treatment of patients with low-risk breast cancer.

Methods And Materials: 274 patients with low-risk breast cancer were treated on protocol. Patients were eligible for the study if the tumor size was < 3 cm, resection margins were clear by at least 2 mm, no lymph node metastases existed, age was >35 years, hormone receptors were positive, and histologic grades were 1 or 2.

Neurokinin 1 receptor gene polymorphism might be correlated with recurrence rates in endometriosis.

Introduction: Dysmenorrhoea is the major symptom in women with endometriosis. Recently, pain modulation through Neurokinin-1-receptor (NK1R) pathways have been investigated in neuropathic pain patients. Aim of this study was, therefore, to examine the effect of a single nucleotide polymorphism (SNP) of the NK1R gene on the susceptibility for endometriosis and the disease free survival (DFS) after surgery for endometriosis.

Pain perception and detailed visual pain mapping in breast cancer survivors.

Chronic pain and neural irritation after breast surgery and radiation are still relevant sequelae of the treatment. Pain quantification and localization in patient groups are difficult to standardize. In order to quantify and localize pain in a group of breast cancer patients, a Java-based program was developed to visualize the frequency of pain in "pain maps.

Are Certified Breast Centers Cost-Effective?

The German health care system has entered an era of specialist centers and certification. Hospitals are required to introduce quality management with external monitoring, refining and improving their quality of treatment. These statutory requirements can only be met through specialization, centralization, and establishing centers and networks with internal and external interdisciplinary collaboration.

Correlates of the desire for improved cosmetic results after breast-conserving therapy and mastectomy in breast cancer patients.

The aim of this survey was to evaluate correlates for the patient's desire for surgical improvement of the cosmetic outcome after the primary operation for breast cancer. A cross-sectional study was carried out in a single follow-up outpatient clinic using a questionnaire. Patients were asked to assess their degree of satisfaction with the cosmetic results of their primary surgery and to state if they would like to undergo a further breast surgery to improve the appearance.
