Correlation of RANK and RANKL with mammographic density in primary breast cancer patients.

Purpose: The receptor activator of nuclear factor kappa B (RANK) and its ligand (RANKL) have been shown to promote proliferation of the breast and breast carcinogenesis. The objective of this analysis was to investigate whether tumor-specific RANK and RANKL expression in patients with primary breast cancer is associated with high percentage mammographic density (PMD), which is a known breast cancer risk factor.

Methods: Immunohistochemical staining of RANK and RANKL was performed in tissue microarrays (TMAs) from primary breast cancer samples of the Bavarian Breast Cancer Cases and Controls (BBCC) study.

Predicting mammographic density with linear ultrasound transducers.

Background: High mammographic density (MD) is a risk factor for the development of breast cancer (BC). Changes in MD are influenced by multiple factors such as age, BMI, number of full-term pregnancies and lactating periods. To learn more about MD, it is important to establish non-radiation-based, alternative examination methods to mammography such as ultrasound assessments.

Comprehensive characterization of endometriosis patients and disease patterns in a large clinical cohort.

Purpose: In many diseases, it is possible to classify a heterogeneous group into subgroups relative to tumor biology, genetic variations, or clinical and pathological features. No such classification is available for endometriosis. In our retrospective case-case analysis we defined subgroups of endometriosis patients relative to the type and location of the endometriosis lesion and relative to basic patient characteristics.

Mammographic density and prognosis in primary breast cancer patients.

Purpose: Mammographic density (MD) is one of the strongest risk factors for breast cancer (BC). However, the influence of MD on the BC prognosis is unclear. The objective of this study was therefore to investigate whether percentage MD (PMD) is associated with a difference in disease-free or overall survival in primary BC patients.

Standards Used by a Clinical and Scientific Endometriosis Center for the Diagnosis and Therapy of Patients with Endometriosis.

Endometriosis is one of the most common benign gynecological diseases. The extremely heterogeneous complex of symptoms complicates the diagnosis and treatment of this disease. In most patients, there is a latency period of several years between the first occurrence of symptoms and the definitive diagnosis.

Situation of Adolescent Contraceptive Use in Germany.

Would adolescent girls in Germany choose a different method of contraception to the combined oral contraceptive if provided with the appropriate information? Is there a need for long-acting contraception among our adolescent girls? How satisfied are female patients with the information they receive at their respective gynaecology practices, and how much do the girls know about different methods of contraception? In the study "Thinking About Needs in COntraception" (TANCO), not only female patients, but also their respective gynaecologists were surveyed online about current methods of contraception, their satisfaction with these methods, and also their level of knowledge concerning the individual methods of contraception, the situation related to advice about different contraceptive options and their general satisfaction with gynaecological care. This article presents the data from the subset of adolescent girls aged 14 to 19 years (n = 2699) out of the total of 18 521 women surveyed. The girls surveyed were familiar with at least the name of more than five different methods of contraception (average 5.

Using automated texture features to determine the probability for masking of a tumor on mammography, but not ultrasound.

Background: Tumors in radiologically dense breast were overlooked on mammograms more often than tumors in low-density breasts. A fast reproducible and automated method of assessing percentage mammographic density (PMD) would be desirable to support decisions whether ultrasonography should be provided for women in addition to mammography in diagnostic mammography units. PMD assessment has still not been included in clinical routine work, as there are issues of interobserver variability and the procedure is quite time consuming.

Association between mammographic density and pregnancies relative to age and BMI: a breast cancer case-only analysis.

Purpose: Percentage mammographic density (PMD) is a major risk factor for breast cancer (BC). It is strongly associated with body mass index (BMI) and age, which are themselves risk factors for breast cancer. This analysis investigated the association between the number of full-term pregnancies and PMD in different subgroups relative to age and BMI.

Correlation of mammographic density and serum calcium levels in patients with primary breast cancer.

Percentage mammographic breast density (PMD) is one of the most important risk factors for breast cancer (BC). Calcium, vitamin D, bisphosphonates, and denosumab have been considered and partly confirmed as factors potentially influencing the risk of BC. This retrospective observational study investigated the association between serum calcium level and PMD.

What do patients want to know about contraception and which method would they prefer?

Purpose: The aim of this study was to determine the extent to which women's choice of contraceptive method depends on the advice received from their gynecologist and whether more intensive counseling might lead to more frequent use of long-acting reversible contraception (LARC).

Methods: A total of 1089 physicians and 18,521 women responded to 32 or 37 questions, respectively, using an online questionnaire. The women were asked about their current use of contraceptive methods, the extent of their satisfaction with them, their satisfaction with the counseling they had received, and whether they wanted to have more information about contraception.

Evaluation of a Marker Clip System in Sonographically Guided Core Needle Biopsy for Breast Cancer Localization Before and After Neoadjuvant Chemotherapy.

The placement of intramammary marker clips has proven to be helpful for tumor localization in patients undergoing neoadjuvant chemotherapy and breast-conserving surgery. The purpose of our study was to investigate the feasibility of using a clip marker system for breast cancer localization and its influence on the imaging assessment of treatment responses after neoadjuvant chemotherapy. Between March and June 2015, a total of 25 patients (n = 25), with a suspicion of invasive breast cancer with diameters of at least 2 cm (cT2), underwent preoperative sonographically guided core needle biopsy using a single-use breast biopsy system (HistoCore™) and intramammary clip marking using a directly adapted clip system based on the established O-Twist Marker™, before their scheduled preoperative neoadjuvant chemotherapy.

Operative techniques and complications of extraction and transplantation of ovarian tissue: the Erlangen experience.

Purpose: Extracting ovarian tissue before oncologic therapy and transplanting it afterwards are increasingly being used to preserve fertility in women. This study describes standardized and safe operative procedures, with few complications, and reports the resulting ovarian function and pregnancy rates.

Methods: The standardized operative techniques for removing and transplanting ovarian tissue used at the Erlangen center are: for tissue removal, one-third to half of the tissue from one ovary is excised with scissors, without tissue coagulation; for subsequent transplantation, pieces of ovarian tissue are placed in a retroperitoneal pocket without closure of the pocket.

Twenty-five-year-old Woman with Bilateral Borderline Ovarian Tumour Desiring to Preserve Fertility - Case Report and Literature Review on the Current State of Fertility Preservation in Women with Borderline Ovarian Tumours.

Borderline ovarian tumours are semimalignant tumours occurring unilaterally or bilaterally with a peak incidence among women of reproductive age. Since the affected women often wish to preserve fertility, particular precautions must be taken when counselling the patient and obtaining consent prior to planning an individual treatment. Options for preserving fertility include an organ-sparing surgical procedure and cryopreservation of oocytes and/or ovarian tissue.

The International Endometriosis Evaluation Program (IEEP Study) - A Systematic Study for Physicians, Researchers and Patients.

Introduction: Endometriosis is a heterogeneous disease characterized by a range of different presentations. It is usually diagnosed when patients present with pain and/or infertility, but it has also been diagnosed in asymptomatic patients. Because of the different diagnostic approaches and diverse therapies, time to diagnosis can vary considerably and the definitive diagnosis may be delayed, with some cases not being diagnosed for several years.

Mammographic density is the main correlate of tumors detected on ultrasound but not on mammography.

Although mammography screening programs do not include ultrasound examinations, some diagnostic units do provide women with both mammography and ultrasonography. This article is concerned with estimating the risk of a breast cancer patient diagnosed in a hospital-based mammography unit having a tumor that is visible on ultrasound but not on mammography. A total of 1,399 women with invasive breast cancer from a hospital-based diagnostic mammography unit were included in this retrospective study.

Fertility Protection in Female Oncology Patients: How Should Patients Be Counseled?

Protecting the fertility of patients with oncologic disease is becoming more and more important, as fulfilling the wish to have children is increasingly occurring at a later stage in life and long-term survival rates after cancer are continuing to improve. A number of fertility-preserving options exist. In addition to techniques which have been around for some time such as medical ovarian suppression, ovarian transposition, and organ-preserving surgery, there are other, more recent, innovative methods which have developed over the last few years such as cryopreservation of oocytes or ovarian tissue transplantation after completing cancer therapy.

Endometriosis as a risk factor for ovarian or endometrial cancer - results of a hospital-based case-control study.

Background: No screening programs are available for ovarian or endometrial cancer. One reason for this is the low incidence of the conditions, resulting in low positive predictive values for tests, which are not very specific. One way of addressing this problem might be to use risk factors to define subpopulations with a higher incidence.

Polymorphisms in a Putative Enhancer at the 10q21.2 Breast Cancer Risk Locus Regulate NRBF2 Expression.

Genome-wide association studies have identified SNPs near ZNF365 at 10q21.2 that are associated with both breast cancer risk and mammographic density. To identify the most likely causal SNPs, we fine mapped the association signal by genotyping 428 SNPs across the region in 89,050 European and 12,893 Asian case and control subjects from the Breast Cancer Association Consortium.

Novel Associations between Common Breast Cancer Susceptibility Variants and Risk-Predicting Mammographic Density Measures.

Mammographic density measures adjusted for age and body mass index (BMI) are heritable predictors of breast cancer risk, but few mammographic density-associated genetic variants have been identified. Using data for 10,727 women from two international consortia, we estimated associations between 77 common breast cancer susceptibility variants and absolute dense area, percent dense area and absolute nondense area adjusted for study, age, and BMI using mixed linear modeling. We found strong support for established associations between rs10995190 (in the region of ZNF365), rs2046210 (ESR1), and rs3817198 (LSP1) and adjusted absolute and percent dense areas (all P < 10(-5)).

The contributions of breast density and common genetic variation to breast cancer risk.

We evaluated whether a 76-locus polygenic risk score (PRS) and Breast Imaging Reporting and Data System (BI-RADS) breast density were independent risk factors within three studies (1643 case patients, 2397 control patients) using logistic regression models. We incorporated the PRS odds ratio (OR) into the Breast Cancer Surveillance Consortium (BCSC) risk-prediction model while accounting for its attributable risk and compared five-year absolute risk predictions between models using area under the curve (AUC) statistics. All statistical tests were two-sided.

Comparison of Sonography versus Digital Breast Tomosynthesis to Locate Intramammary Marker Clips.

This study aimed to compare the accuracy of sonography versus digital breast tomosynthesis to locate intramammary marker clips placed under ultrasound guidance. Fifty patients with suspicion of breast cancer (lesion diameter less than 2 cm [cT1]) had ultrasound-guided core needle biopsy with placement of a marker clip in the center of the tumor. Intramammary marker clips were subsequently located with both sonography and digital breast tomosynthesis.

Association of molecular subtypes with breast cancer risk factors: a case-only analysis.

As breast cancer (BC) screening identifies many BCs with a good prognosis, which might be overdiagnosed and therefore overtreated, the identification of subgroups with a high risk for aggressive subtypes might be helpful. The aim of this case-case analysis was to investigate the association between epidemiological risk factors and molecular subtypes in a cohort of BC patients. Epidemiological risk factors for 2587 BC patients were obtained using a structured questionnaire and from the patients' charts.

Full Field Digital Mammography (FFDM) versus CMOS Technology, Specimen Radiography System (SRS) and Tomosynthesis (DBT) - Which System Can Optimise Surgical Therapy?

This prospective clinical study aimed to evaluate whether it would be possible to reduce the rate of re-excisions using CMOS technology, a specimen radiography system (SRS) or digital breast tomosynthesis (DBT) compared to a conventional full field digital mammography (FFDM) system. Between 12/2012 and 2/2013 50 patients were diagnosed with invasive breast cancer (BI-RADS™ 5). After histological verification, all patients underwent breast-conserving therapy with intraoperative imaging using 4 different systems and differing magnifications: 1.

Breast Cancer Risk - From Genetics to Molecular Understanding of Pathogenesis.

Several advancements over the last decade have triggered the developments in the field of breast cancer risk research. One of them is the availability of the human genome sequence along with cheap genotyping possibilities. Another is the globalization of research, which has led to the growth of research collaboration into large international consortia that facilitate the pooling of clinical and genotype data of hundreds of thousands of patients and healthy control individuals.

Evaluation of Newly Adapted Clip Marker System in Ultrasound-Guided Core Needle Biopsy for Suspicion of Breast Cancer.

A newly adapted clip system for intramammary marking during ultrasound-guided core needle biopsy for suspicion of breast cancer is described and evaluated here. Fifty patients with suspicion of breast cancer (cT2) had ultrasound-guided core needle biopsy using a newly adapted clip marker system (HistoCore™ and O-Twist Marker™). Subsequently, ultrasound follow-up and tomosynthesis scans were done to determine the location of the marker clips.
