Psycho-oncology care in breast cancer centres: a nationwide survey.

OBJECTIVE: To describe psycho-oncological care structures and processes in German breast cancer centres from the perspective of the centre administration. METHODS: The findings are based on a postal survey of a representative random sample of surgical sites of certified breast cancer centres in Germany. Data were collected in 2013 and 2014. The questionnaire included questions about infrastructure, patient information standards, psycho-oncological services and aspects of organisational culture. Data analyses included frequencies, means and bivariate relationships. RESULTS: The return rate was 88.3% (53 hospital sites). Psycho-oncological care is provided by permanent employees in 87%. The average number of full-time-equivalent employees (FTE) is 1.23. Most breast cancer centres engage the occupational group of psycho-oncologists for psycho-oncological care (90%), followed by the medical service (80%) and breast care nurses (78%) (multiple answers were possible). The correlation coefficient between FTEs and surgical treatments per year is not significant (r=0.292, p=0.051). Hospitals are screening every inpatient for the need of psycho-oncological support in 76% of all sites. Frequently used screening instruments are distress thermometer (19%), clinical interview (13%) and basic psycho-oncological documentation (11%). CONCLUSION: Our data provide insights into the self-reported structural and procedural quality of psycho-oncological care in German breast cancer centres. Further research should examine patient and caregiver perspective on the psycho-oncological services provided by breast cancer centres.

Current approaches in the clinical management of pregnancy-associated breast cancer-pros and cons.

Malignancies are one of the leading causes of mortality in women during their reproductive life. Treatment of gynecological malignant tumors during pregnancy is possible but not simple, since it creates a conflict between care of the mother and the fetus. BC is the most prevalent malignancy diagnosed in pregnancy, ranking up to 21% of all pregnancy-related malignancies. Due to its stets increasing prevalence, aggressive cancer subtype, and severe ethical and psychological aspects linked to the disease, experts raise an alarm for an acute necessity to improve the overall management of the PABC-the issue which has strongly motivated our current paper. Comprehensive research data and clinical experience accumulated in recent years have advanced our understanding of the disease complexity. PABC treatment must be individualized with an emphasis on optimal care of the mother, while observing standard treatment protocols with regard to safety of the fetus. Treatment protocols should be elaborated based on the individualized patient profile, bearing in mind the acute danger to the mother, maximizing the therapy efficacy and minimizing harmful effects to the fetus. Complex consulting on treatment options, their impacts on pregnancy and potential teratogenic effects requires tight "doctor-patient" collaboration. Complications that may arise due to the treatment of breast cancer in pregnancy require a multiprofessional expertise including oncologists, neonatologists, perinatologists, obstetricians, teratologists, and toxicologists, and an extensive psychological support throughout the pregnancy and after giving birth. Thereby, specifically psychological aspects of PABC diagnosis and follow-up are frequently neglected, being not yet adequately explored in the entire disease management approach. Herewith, we update the status quo regarding the currently available diagnostic modalities, complex treatment algorithms, and novel clinical approaches which altogether argue for an urgent necessity of a paradigm shift moving away from reactive to predictive, preventive, and personalized medical approach in the overall management of PABC meeting the needs of young populations, persons at high risk, affected patients, and families as the society at large.

Premenopausal breast cancer: potential clinical utility of a multi-omics based machine learning approach for patient stratification.

BACKGROUND: The breast cancer (BC) epidemic is a multifactorial disease attributed to the early twenty-first century: about two million of new cases and half a million deaths are registered annually worldwide. New trends are emerging now: on the one hand, with respect to the geographical BC prevalence and, on the other hand, with respect to the age distribution. Recent statistics demonstrate that young populations are getting more and more affected by BC in both Eastern and Western countries. Therefore, the old rule "the older the age, the higher the BC risk" is getting relativised now. Accumulated evidence shows that young premenopausal women deal with particularly unpredictable subtypes of BC such as triple-negative BC, have lower survival rates and respond less to conventional chemotherapy compared to the majority of postmenopausal BC. WORKING HYPOTHESIS: Here we hypothesised that a multi-level diagnostic approach may lead to the identification of a molecular signature highly specific for the premenopausal BC. A multi-omic approach using machine learning was considered as a potent tool for stratifying patients with benign breast alterations into well-defined risk groups, namely individuals at high versus low risk for breast cancer development. RESULTS AND CONCLUSIONS: The study resulted in identifying multi-omic signature specific for the premenopausal BC that can be used for stratifying patients with benign breast alterations. Our predictive model is capable of discriminating individually between high and low BC-risk with high confidence (>90%) and considered of potential clinical utility. Novel risk assessment approaches and advanced screening programmes-as the long-term target of this project-are of particular importance for predictive, preventive and personalised medicine as the medicine of the future, due to the expected health benefits for young subpopulations and the healthcare system as a whole.

Prostate-specific membrane antigen in breast cancer: a comprehensive evaluation of expression and a case report of radionuclide therapy.

PURPOSE: Prostate-specific membrane antigen (PSMA), a protein product of the folate hydrolase 1 (FOLH1) gene, is gaining increasing acceptance as a target for positron emission tomography/computer tomography (PET/CT) imaging in patients with several cancer types, including breast cancer. So far, PSMA expression in breast cancer endothelia has not been sufficiently characterized. METHODS: This study comprised 315 cases of invasive carcinoma of no special type (NST) and lobular breast cancer (median follow-up time 9.0 years). PSMA expression on tumor endothelia was detected by immunohistochemistry. Further, vascular mRNA expression of the FOLH1 gene (PSMA) was investigated in a cohort of patients with invasive breast cancer provided by The Cancer Genome Atlas (TCGA). RESULTS: Sixty percent of breast cancer cases exhibited PSMA-positive endothelia with higher expression rates in tumors of higher grade, NST subtype with Her2-positivity, and lack of hormone receptors. These findings were confirmed on mRNA expression levels. The highest PSMA rates were observed in triple-negative carcinomas (4.5 × higher than in other tumors). Further, a case of a patient with metastatic breast cancer showing PSMA expression in PET/CT imaging and undergoing PSMA radionuclide therapy is discussed in detail. CONCLUSIONS: This study provides a rationale for the further development of PSMA-targeted imaging in breast cancer, especially in triple-negative tumors.

Preoperative breast MRI-examination for all patients with histologically proven breast cancer? A concept for a prospective multicenter trial.

Background A published retrospective data of our study group demonstrated that premenopausal women, patients with lobular invasive breast cancer or patients with high breast density [American College of Radiology (ACR) classification 3+4] significantly benefit from magnetic resonance imaging (MRI) leading to additional detection of malignant foci of 20.2% in the index and 2.5% in the contralateral breast, which would otherwise not be detected by routine imaging. Critics of preoperative MRI focus on higher false-positive rates leading to unnecessary surgical procedures and mastectomies. Therefore, MRI in preoperative imaging remains controversial. Methods To validate our retrospective data we initiate a prospective one-armed multicenter trial for patients with histologically confirmed breast cancer performing routine imaging by ultrasound and mammography followed by MRI imaging based on menopause status, histologic subtype, ACR and Breast Imaging Reporting and Data System (BIRADS)-classification. Primary endpoint is the rate of additional findings and change of treatment strategy, secondary endpoints are local recurrence-free, distant recurrence-free and overall survival. Additional MRI findings are calculated to be above 10% with a number of 100 patients recruited and a power of 80%. Conclusion MRI is detecting more tumor foci than conventional imaging but remains controversial in primary breast cancer for preoperative imaging because of the fear of over-diagnosis and the increased morbidity of additional potentially unnecessary surgical procedures. This planned one-armed prospective multicenter trial is designed to confirm our retrospectively revealed data defining subgroups with significant benefit of preoperative MRI to come to a consensus avoiding over-diagnosis and false-positive results leading to clinically beneficial and cost-effective use of preoperative MRI.

Whole exome sequencing and array-based molecular karyotyping as aids to prenatal diagnosis in fetuses with suspected Simpson-Golabi-Behmel syndrome.

OBJECTIVE: Simpson-Golabi-Behmel (SGBS) syndrome type 1 and type 2 represent rare X-linked prenatal overgrowth disorders. The aim of our study is to describe the prenatal sonographic features as well as the genetic work-up. METHOD: Retrospective analysis of four cases with a pre- or postnatal diagnosis of SGBS in a single tertiary referral center within a period of 4 years. RESULTS: In the study period, four male fetuses with SGBS were detected. The final diagnosis was made prenatally in three cases. In all cases the second trimester anomaly scan revealed left sided congenital diaphragmatic hernia (CDH) with additional anomalies; three fetuses with SGBS type 1 showed fetal overgrowth. In two of these, whole exome sequencing showed a possible frameshift mutation and a point mutation in the gene GPC3, respectively. In the third case, multiplex ligation-dependent probe amplification (MLPA) revealed a hemizygous duplication of exon 3-7 in the gene GPC3. In the fourth case, SGBS type 2 was confirmed by array comparative genomic hybridization (CGH) of amniotic fluid cells showing a deletion of the gene OFD1. CONCLUSION: We could demonstrate, that in the presence of a CDH, syndromes of the fetus can be increasingly differentiated by detailed sonography followed by a selective and graded molecular diagnostic using microarray techniques and whole exome sequencing. © 2016 John Wiley & Sons, Ltd.
