Bone-modifying agents for reducing bone loss in women with early and locally advanced breast cancer: a network meta-analysis.

BACKGROUND: Bisphosphonates and receptor activator of nuclear factor-kappa B ligand (RANKL)-inhibitors are amongst the bone-modifying agents used as supportive treatment in women with breast cancer who do not have bone metastases. These agents aim to reduce bone loss and the risk of fractures. Bisphosphonates have demonstrated survival benefits, particularly in postmenopausal women. OBJECTIVES: To assess and compare the effects of different bone-modifying agents as supportive treatment to reduce bone mineral density loss and osteoporotic fractures in women with breast cancer without bone metastases and generate a ranking of treatment options using network meta-analyses (NMAs). SEARCH METHODS: We identified studies by electronically searching CENTRAL, MEDLINE and Embase until January 2023. We searched various trial registries and screened abstracts of conference proceedings and reference lists of identified trials. SELECTION CRITERIA: We included randomised controlled trials comparing different bisphosphonates and RANKL-inihibitors with each other or against no further treatment or placebo for women with breast cancer without bone metastases. DATA COLLECTION AND ANALYSIS: Two review authors independently extracted data and assessed the risk of bias of included studies and certainty of evidence using GRADE. Outcomes were bone mineral density, quality of life, overall fractures, overall survival and adverse events. We conducted NMAs and generated treatment rankings. MAIN RESULTS: Forty-seven trials (35,163 participants) fulfilled our inclusion criteria; 34 trials (33,793 participants) could be considered in the NMA (8 different treatment options). Bone mineral density We estimated that the bone mineral density of participants with no treatment/placebo measured as total T-score was -1.34. Evidence from the NMA (9 trials; 1166 participants) suggests that treatment with ibandronate (T-score -0.77; MD 0.57, 95% CI -0.05 to 1.19) may slightly increase bone mineral density (low certainty) and treatment with zoledronic acid (T-score -0.45; MD 0.89, 95% CI 0.62 to 1.16) probably slightly increases bone mineral density compared to no treatment/placebo (moderate certainty). Risedronate (T-score -1.08; MD 0.26, 95% CI -0.32 to 0.84) may result in little to no difference compared to no treatment/placebo (low certainty). We are uncertain whether alendronate (T-score 2.36; MD 3.70, 95% CI -2.01 to 9.41) increases bone mineral density compared to no treatment/placebo (very low certainty). Quality of life No quantitative analyses could be performed for quality of life, as only three studies reported this outcome. All three studies showed only minimal differences between the respective interventions examined. Overall fracture rate We estimated that 70 of 1000 participants with no treatment/placebo had fractures. Evidence from the NMA (16 trials; 19,492 participants) indicates that treatment with clodronate or ibandronate (42 of 1000; RR 0.60, 95% CI 0.39 to 0.92; 40 of 1000; RR 0.57, 95% CI 0.38 to 0.86, respectively) decreases the number of fractures compared to no treatment/placebo (high certainty). Denosumab or zoledronic acid (51 of 1000; RR 0.73, 95% CI 0.52 to 1.01; 55 of 1000; RR 0.79, 95% CI 0.56 to 1.11, respectively) probably slightly decreases the number of fractures; and risedronate (39 of 1000; RR 0.56, 95% CI 0.15 to 2.16) probably decreases the number of fractures compared to no treatment/placebo (moderate certainty). Pamidronate (106 of 1000; RR 1.52, 95% CI 0.75 to 3.06) probably increases the number of fractures compared to no treatment/placebo (moderate certainty). Overall survival We estimated that 920 of 1000 participants with no treatment/placebo survived overall. Evidence from the NMA (17 trials; 30,991 participants) suggests that clodronate (924 of 1000; HR 0.95, 95% CI 0.77 to 1.17), denosumab (927 of 1000; HR 0.91, 95% CI 0.69 to 1.21), ibandronate (915 of 1000; HR 1.06, 95% CI 0.83 to 1.34) and zoledronic acid (925 of 1000; HR 0.93, 95% CI 0.76 to 1.14) may result in little to no difference regarding overall survival compared to no treatment/placebo (low certainty). Additionally, we are uncertain whether pamidronate (905 of 1000; HR 1.20, 95% CI 0.81 to 1.78) decreases overall survival compared to no treatment/placebo (very low certainty). Osteonecrosis of the jaw We estimated that 1 of 1000 participants with no treatment/placebo developed osteonecrosis of the jaw. Evidence from the NMA (12 trials; 23,527 participants) suggests that denosumab (25 of 1000; RR 24.70, 95% CI 9.56 to 63.83), ibandronate (6 of 1000; RR 5.77, 95% CI 2.04 to 16.35) and zoledronic acid (9 of 1000; RR 9.41, 95% CI 3.54 to 24.99) probably increases the occurrence of osteonecrosis of the jaw compared to no treatment/placebo (moderate certainty). Additionally, clodronate (3 of 1000; RR 2.65, 95% CI 0.83 to 8.50) may increase the occurrence of osteonecrosis of the jaw compared to no treatment/placebo (low certainty). Renal impairment We estimated that 14 of 1000 participants with no treatment/placebo developed renal impairment. Evidence from the NMA (12 trials; 22,469 participants) suggests that ibandronate (28 of 1000; RR 1.98, 95% CI 1.01 to 3.88) probably increases the occurrence of renal impairment compared to no treatment/placebo (moderate certainty). Zoledronic acid (21 of 1000; RR 1.49, 95% CI 0.87 to 2.58) probably increases the occurrence of renal impairment while clodronate (12 of 1000; RR 0.88, 95% CI 0.55 to 1.39) and denosumab (11 of 1000; RR 0.80, 95% CI 0.54 to 1.19) probably results in little to no difference regarding the occurrence of renal impairment compared to no treatment/placebo (moderate certainty). AUTHORS' CONCLUSIONS: When considering bone-modifying agents for managing bone loss in women with early or locally advanced breast cancer, one has to balance between efficacy and safety. Our findings suggest that bisphosphonates (excluding alendronate and pamidronate) or denosumab compared to no treatment or placebo likely results in increased bone mineral density and reduced fracture rates. Our survival analysis that included pre and postmenopausal women showed little to no difference regarding overall survival. These treatments may lead to more adverse events. Therefore, forming an overall judgement of the best ranked bone-modifying agent is challenging. More head-to-head comparisons, especially comparing denosumab with any bisphosphonate, are needed to address gaps and validate the findings of this review.

Prevalence and Obstetric Management Changes During the COVID-19 Pandemic in Peripartum SARS-CoV-2-Positive Women - an Analysis of the CRONOS Registry Data.

The analysis of CRONOS data for this article presents the infection prevalence among parturients and subsequent changes in obstetric management over time in Germany. 2,184 women with peripartum SARS-CoV-2 infection (<14d before birth) were included. Monthly period prevalence was calculated using the number of affected women on the CRONOS registry relative to total monthly births in each hospital from March 2020 to May 2022 and compared to RKI data. Trends related to changes in obstetric management were calculated based on severity of illness. By June 2021, the obstetric population shows a discretely higher infection prevalence compared to the general population, falling below the RKI reported prevalence by October 2021. The overall rate of iatrogenic deliveries remains unchanged over time (p-value for trend=0.779). During wave 1 to 4, deliveries due to SARS-CoV-2 infection rose among moderately to severely ill women (p-value for trend 0.0000) and was increased compared to moderately ill women (p=0.001). We showed that comprehensive screening provides timely information on infection prevalence. Recruitment fatigue caused by higher clinician workload due to increased admissions and more cases with severe illness probably caused reduced prevalence reporting. Changes in obstetric management were related to COVID-19 symptom severity. A comprehensive national perinatal registry is needed to examine other areas of perinatal care in Germany.

Implications for surveillance for breast cancer patients based on the internally and externally validated BRENDA-metastatic recurrence score.

PURPOSE: Although the incidence of distant relapse is decreasing, 20-30% of patients with early breast cancer die of metastasis. The aim of this study is to characterize patients with metastasis-free survival(MFS) less than 5 years, to analyze the most probable site of metastases according to the internally and externally validated BRENDA-score. The BRENDA-score is a combination of the biological subtype and clinical staging. METHOD: 3832 patients with primary diagnosis of breast cancer and either distant metastatic recurrence within 5 years or MFS ≥ 5 years were assigned to this study. Patients were classified for metastatic recurrence according to the BRENDA-score. 1765 patients were in a validation set. Statistical methods were Kaplan-Meier curves, Cox regression analysis, Exhausted CHAID, likelihood-ratio tests and the Nearest Neighbor Estimation method. RESULTS: There was a significant(p < 0.001) difference between the Kaplan-Meier MFS-functions of M0-patients stratified by BRENDA-score. The BRENDA score outperforms intrinsic subtypes and the Nottingham prognostic score. It fits the original data and the validation set equally well (p = 0.179).There was a significant(p < 0.001) difference between mean BRENDA-Index for patients with MFS < 5y(21.0 ± 9.0) and patients with MFS ≥ 5y(mean BRENDA-Index 11.7 ± 8.2). 55.6% of the very high risk patients(BRENDA-Index ≥ 27) had metastases within 5 years. The most likely primary metastatic site was bone(30%) followed by liver(19%) and lung(18%). The discriminatory ability(areas under the time dependent ROC curve) of the BRENDA score is good to acceptable for the first 5 years. In the very low/low risk (intermediate, high/very high) risk group 50% of all metastases were diagnosed within 26 months. Guideline adherence had a highly significant influence on outcome independent of the risk group. CONCLUSION: The evaluation showed that the BRENDA-Score is a robust predictive tool for breast cancer recurrence and site of metastases in the first five years after diagnosis. It outperforms intrinsic subtypes and the Nottingham prognostic score. The BRENDA-score could be a tool for a risk orientated and targeted follow up.

Patients' perceived challenges, competencies, and supportive care needs during acute clinical treatment of breast or gynecological cancer.

OBJECTIVE: This study aimed to examine challenges, competencies, and supportive care needs (SCN) of women with breast or gynecological cancer during acute cancer treatment and associations to other health-related variables. METHODS: We surveyed 120 patients with breast or gynecological cancer at the end of acute cancer treatment, either directly after surgery or during adjuvant chemotherapy. We assessed challenges, subjective competencies, and SCN using a self-developed measure comprising 25 items referring to coping tasks assigned to six domains. In addition, patients' competencies and health literacy (HL) were assessed. RESULTS: Most patients felt at least moderately challenged by coping tasks concerning psychological distress (e.g., dealing with fears and insecurities, 70.2%; coping with cancer diagnosis, 69.6%) and physical complaints (e.g., dealing with a reduced physical capacity, 56.6%). About 42.5%-71.4% of patients who evaluated coping tasks as highly challenging felt competent to deal with these challenges themselves. Less than half of patients reported SCN, mainly regarding psychological concerns. The extent of challenging coping tasks, patients' perceived ability to overcome challenges themselves, and SCN showed associations to patient competencies and HL. CONCLUSIONS: SCN regarding psychological concerns and health behavior should be addressed in acute cancer care and rehabilitation programs. In addition, promoting HL might be essential in strengthening patients' subjective competencies related to various coping tasks.

Psychological distress in breast cancer patients during oncological inpatient rehabilitation: incidence, triggering factors and correlation with treatment-induced side effects.

As a result of the cancer diagnosis and the mostly multimodal, stressful therapy, psychological distress is a common symptom in breast cancer patients. As part of this prospective study, 1400 patients who were admitted to the hospital for oncological rehabilitation were screened for distress and somatic, therapy-induced secondary disorders. Mean distress in the screened population was 5.6 ± 2.56 (range 0-10). In 942 cases (67.3%) a significant distress score (≥ 5) was detected and in 587 cases (41.9%) very high levels of distress (≥ 7) was observed. Psychological distress significantly correlated with younger age, presence of triple negative breast cancer (TNBC), tumor recurrence and metastasis, and inability to work. Treatment-induced side effects such as lymphedema, CIPN or extensive tumor resection (mastectomy) showed a (not significant) trend for higher distress. The high incidence of distress underscores the importance of psycho-oncological therapy offers and the great importance of occupational measures during oncological rehabilitation such as the importance of a successful return to work for a better quality of life in breast cancer patients.

Morphokinetic analysis of early human embryonic development and its relationship to endometriosis resection: a retrospective time-lapse study using the KIDScore™ D3 and D5 implantation data algorithm.

RESEARCH QUESTION: Does complete resection of endometriosis improve embryo quality as assessed by morphokinetic parameters using time-lapse microscopy? DESIGN: For this retrospective study we analysed 237 fertilised, cultured and transferred embryos from 128 fresh IVF and/ or ICSI transfer cycles. Endometriosis was confirmed or excluded by laparoscopy. Patients were stimulated with recombinant FSH using GnRH agonist and antagonist protocols. After fertilisation, a time-lapse incubation system was used for observation. Embryo quality was assessed using the KIDScore™ D3 and D5 implantation data algorithm. RESULTS: The analysis showed a median KIDScore™ D5 of 2.6 (on a scale of 1 to 9.9) for embryos from patients with endometriosis without complete resection. The control group without endometriosis achieved a score of 6.8 (p = 0.003). The median score for embryos from endometriosis patients with complete resection was 7.2, which was a significant increase compared to embryos from patients without complete resection (p = 0.002). We observed an effect size of r = 0.4 for complete resection versus no resection of endometriosis using the KIDScore™ D5. There were no differences in KIDScore™ D3 between the three patient groups. Pregnancy and miscarriage rates showed the same clinical trends. In three of our four case series of patients who underwent IVF/ ICSI cycles before and after complete resection, we found a marked improvement in embryo quality after complete resection. CONCLUSIONS: Complete resection of endometriosis could significantly improve the otherwise poor embryo quality of patients undergoing IVF-procedures. The data, therefore, strongly support recommending surgery to patients with endometriosis prior to assisted reproduction.

Awareness, offer, and use of psychosocial services by breast cancer survivors in Germany: a prospective multi-centre study.

PURPOSE: This study examined the pattern of psychosocial care in breast cancer survivors. METHODS: In a prospective study with measurements before surgery, 1 month, 8 months, and 5 years thereafter, we examined the proportion of breast cancer survivors who were aware about, had been offered and received various types of psychosocial services from psychologists, social workers, doctors, self-help groups etc. The degree of helpfulness per service among users was ascertained with Likert scales. Determinants of awareness, offer and use were investigated using binary logistic regression analyses. How the services are inter-related was tested with principal component analyses. RESULTS: Among 456 breast cancer survivors who participated until 5 years, psychological services were known by 91%, offered to 68%, and used by 55% of patients. Social services were known by 86%, offered to 65%, and used by 51%. Women ≥ 65 years were less likely to be informed about (odds ratio (OR) 0.2) and get offers for psychosocial services (OR 0.4 for social and 0.5 for psychological services) than women < 65 years. The services rated most helpful were social services in the hospital, psychological counselling by a consultant and psychotherapy in private practices. CONCLUSION: These findings underline the importance of psychosocial support by physicians in addition to the "professional" mental health and social care providers. They also show that elderly women in need for support might be in danger of not being well-informed about the services available.

Association of social service counseling in breast cancer patients with financial problems, role functioning and employment-results from the prospective multicenter BRENDA II study.

BACKGROUND: This study examined the relationship between social service counseling (SSC) and financial and role functioning problems in primary breast cancer (BC) patients over a 5-year observation period. METHODS: In the multicenter prospective study, patients were approached before surgery (t1), before initiation of adjuvant treatment (t2), after therapy completion (t3), and 5 years after surgery (t4). We examined the proportion of BC survivors who had financial and role functioning problems and the proportion who were employed at t4. We examined how frequently patients were informed about, offered, or used SSC, and we used multivariate logistic regression analyses to examine the relationship between this and financial and role functioning problem prevalence. RESULTS: Of the 456 BC survivors, 33% had financial problems and 22% reported role functioning problems at t4. There was no evidence that women with increased financial problems were informed about SSC more often than those without (OR 1.1, p = 0.84) or that they used SSC more often (OR 1.3, p = 0.25). However, women with role functioning problems were informed about SSC significantly more often (OR 1.7, p = 0.02) and attended counseling significantly more often (OR 1.6, p = 0.03). Among participants aged < 65 years at t4 (n = 255), 70% were employed. Patients who had received SSC were more likely to be employed at t4 than patients who did not (OR 1.9, p = 0.04). CONCLUSION: These findings underline the importance of SSC for BC patients with role functioning issues. They indicate that individuals who use SSC are more likely to be employed later on than individuals who do not.

Optimized process quality in certified breast centers through adherence to stringent diagnostic and therapeutic algorithms effects of structural as well as socio-demographic factors on start of therapy.

PURPOSE: An increasing incidence of breast cancer can be observed worldwide. Since a delay of therapy can have a negative impact on prognosis, timely cancer care is an important quality indicator. By receiving treatment at a certified breast cancer center, the patient has the best chance of treatment in accordance with guidelines and the best prognosis. The identification of risk factors for a delay of therapy is of central importance and should be the basis for a continuous optimization of treatment at breast cancer centers. METHODS: This retrospective study included women with breast cancer (primary diagnosis, relapse, or secondary malignancy) at the University Hospital Würzburg in 2019 and 2020. Data were retrieved from patients' records. Correlations and regression analyses were performed to detect potential risk factors for treatment delay. RESULTS: Patients who received the histological confirmation of breast cancer at an external institution experienced a later therapy start than those patients who received the histological confirmation at the University Hospital Würzburg itself. (35.7 vs. 32.2 days). The interval between histological confirmation and the first consultation at the University Hospital Würzburg correlated statistically significant with age, distress and distance to the hospital. CONCLUSION: Patients with an in-house diagnosis of breast cancer are treated more quickly than those whose diagnosis was confirmed in an external institution. We identified factors such as increased age, greater distance to the hospital as well as increased distress to prolong the time until start of oncological treatment. Intensified patient care should be offered to these subgroups.

[Patient Competence for Coping with Disease - A Qualitative Analysis in Women with Breast and Gynaecological Cancer]. / Patientenkompetenz zur Krankheitsbewältigung ­ Eine qualitative Analyse bei Frauen mit Brustkrebs und gynäkologischen Tumoren.

OBJECTIVE: The study explores challenges, competencies, and helpful support in coping with the disease of patients with breast cancer and gynaecological cancer and how patient competence as an interaction of these factors might be promoted. METHODS: Semi-structured interviews were conducted with 19 patients in acute care, 20 patients undergoing rehabilitation, and 16 participants in a self-help group and evaluated using qualitative content analysis. RESULTS: The challenges are summarised in the main categories - diagnosis processing, treatment/recurrence fears, illness processing and adaptation, worries about relatives, reactions of the social environment, and worries about the workplace. The named personal competencies in dealing with these challenges were assigned to the following main categories: cognition-related coping, action-related coping, self-regulation illness processing, obtaining and accepting support, self-determined communication of the illness, identifying and applying helpful strategies, illness-related experience, favourable life circumstances, openness to offers of help. Helpful emotional, informational or instrumental support is perceived by relatives, friends, animals, colleagues/employers, treatment providers, rehabilitation, fellow patients, self-help, and counselling facilities. DISCUSSION: The women describe a variety of competencies, which corresponds to a needs-oriented, self-directed coping process. The individuality and complexity of the interaction of the components of patient competence underline the relevance of patient-oriented care. Empowerment and an active patient role are necessary to promote their coping skills according to their needs. Support from practitioners or the private environment can reduce challenges or promote competencies and application.

PERFORM: a non-interventional study assessing the patients' treatment starting with 1L palbociclib in HR+/HER2- ABC.

The prospective, non-interventional PERFORM study describes and analyzes the effectiveness of palbociclib in combination with endocrine therapy (aromatase inhibitor or fulvestrant) as first-line treatment for patients with locally advanced or metastatic HR+/HER2- breast cancer in the real-world setting in Germany and Austria. PERFORM will reflect current patient characteristics and routine treatment patterns including treatment sequences and time to subsequent (chemo)therapy. Besides, second-line treatment effectiveness and patient-relevant end points such as longitudinal patient-reported outcome measurements beyond disease progression will be analyzed. Accounting for the heterogenous real-world patient population, data on clinicopathologic subgroups underrepresented in clinical trials such as elderly or male will be analyzed. Taken together, PERFORM will close knowledge gaps from clinical trials in real world.

Palbociclib in combination with endocrine therapy is the standard first-line treatment for patients with advanced HR+/HER2- breast cancer. Data from clinical trials have shown high response rates and good tolerability. To support these data and close potential knowledge gaps, we conduct the multicenter, observational PERFORM study to evaluate the effectiveness and patient-reported outcomes in patients with advanced HR+/HER2- breast cancer treated with endocrine-based palbociclib therapy in routine clinical practice in Germany. Clinical Trial Registration: NCT04767594 (ClinicalTrials.gov) Sponsor: Pfizer Pharma GmbH, Linkstraße 10, D-10785 Berlin, Germany.

The impact of the COVID-19 pandemic on stress and other psychological factors in pregnant women giving birth during the first wave of the pandemic.

BACKGROUND: The onset of mental illness such as depression and anxiety disorders in pregnancy and postpartum period is common. The coronavirus induced disease 2019 (COVID-19) pandemic and the resulting public policy responses represent an exceptional situation worldwide and there are hints for adverse psychosocial impact, hence, the study of psychological effects of the pandemic in women during hospitalization for delivery and in the postpartum period is highly relevant. METHODS: Patients who gave birth during the first wave of the COVID-19 pandemic in Germany (March to June 2020) at the Department of Obstetrics and Gynecology, University of Würzburg, Germany, were recruited at hospital admission for delivery. Biosamples were collected for analysis of SARS-CoV-2 infection and various stress hormones and interleukin-6 (IL-6). In addition to sociodemographic and medical obstetric data, survey questionnaires in relation to concerns about and fear of COVID-19, depression, stress, anxiety, loneliness, maternal self-efficacy and the mother-child bonding were administered at T1 (delivery stay) and T2 (3-6 months postpartum). RESULTS: In total, all 94 recruited patients had a moderate concern of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at T1 with a significant rise at T2. This concern correlated with low to low-medium general psychosocial stress levels and stress symptoms, and the women showed a significant increase of active coping from T1 to T2. Anxiety levels were low and the Edinburgh Postnatal Depression Scale showed a medium score of 5 with a significant (T1), but only week correlation with the concerns about SARS-CoV-2. In contrast to the overall good maternal bonding without correlation to SARS-CoV-2 concern, the maternal self-efficiency correlated negatively with the obstetric impairment caused by the COVID-19 pandemic. CONCLUSION: Obstetric patients` concerns regarding SARS-CoV-2 and the accompanying pandemic increased during the course of the pandemic correlating positively with stress and depression. Of note is the increase in active coping over time and the overall good mother-child-bonding. Maternal self-efficacy was affected in part by the restrictions of the pandemic. Clinical trial registration DRKS00022506.

The global pandemic of COVID-19 (coronavirus induced disease 2019) is challenging our society in many ways. Especially pregnant women are facing extraordinary conditions and worries, like uncertain risks for mother and fetus in case of infection, restricted prenatal classes or restricted visitor regulations in hospitals. Particularly it is known that pregnancy and the postnatal period are presenting a more psychologically vulnerable time in a woman's life. Developing the GeZeCO study, we aimed to focus on the pandemic's effects on mental health of pregnant women during this time. Women giving birth in the department of obstetrics of the University Hospital Würzburg were asked to participate in the study. In total, 94 women completed several questionnaires concerning their mental health postpartum and again after 3 to 6 months. Further, we took blood samples of the women during the delivery stay and registered sociodemographic and obstetric data. Our results showed, that the women's concern relating to COVID-19, as well as the level of depression and anxiety raised during the pandemic. In addition, the self-efficacy of the mothers was affected by the restriction measures. Despite this, the women had at large a good mother­child-bonding and their competence of active coping increased during time. In summary, we did find that the mental health of obstetric patients is impaired by the COVID-19 pandemic. This points out the importance of not only attending to physical health but also taking care of psychological stress and mental health problems of obstetric patients during this exceptional time.

Introducing a novel model for simulating large loop excision of the transformation zone (LLETZ) using 3D printing technique.

PURPOSE: Electrosurgery is the gold-standard procedure for the treatment of cervical dysplasia. The quality of the outcome depends on the accuracy of performance, which underlines the role of adequate training of surgeons, especially, as this procedure is often performed by novice surgeons. According to our knowledge, medical simulation has up until now lacked a model, which focuses on realistically simulating the treatment of cervical dysplasia with the concerning anatomy. METHODS AND RESULT: In our work, we present a model created using 3D printing for holistically simulating diagnostic, as well as surgical interventions of the cervix, as realistically as possible. CONCLUSION: This novel simulator is compared to an existing model and both are evaluated. By doing so, we aim to provide novice gynecologists with standardized and high-quality simulation models for practicing to improve their proficiency.

Analysis of microRNAs in Exosomes of Breast Cancer Patients in Search of Molecular Prognostic Factors in Brain Metastases.

Brain metastases are the most severe tumorous spread during breast cancer disease. They are associated with a limited quality of life and a very poor overall survival. A subtype of extracellular vesicles, exosomes, are sequestered by all kinds of cells, including tumor cells, and play a role in cell-cell communication. Exosomes contain, among others, microRNAs (miRs). Exosomes can be taken up by other cells in the body, and their active molecules can affect the cellular process in target cells. Tumor-secreted exosomes can affect the integrity of the blood-brain barrier (BBB) and have an impact on brain metastases forming. Serum samples from healthy donors, breast cancer patients with primary tumors, or with brain, bone, or visceral metastases were used to isolate exosomes and exosomal miRs. Exosomes expressed exosomal markers CD63 and CD9, and their amount did not vary significantly between groups, as shown by Western blot and ELISA. The selected 48 miRs were detected using real-time PCR. Area under the receiver-operating characteristic curve (AUC) was used to evaluate the diagnostic accuracy. We identified two miRs with the potential to serve as prognostic markers for brain metastases. Hsa-miR-576-3p was significantly upregulated, and hsa-miR-130a-3p was significantly downregulated in exosomes from breast cancer patients with cerebral metastases with AUC: 0.705 and 0.699, respectively. Furthermore, correlation of miR levels with tumor markers revealed that hsa-miR-340-5p levels were significantly correlated with the percentage of Ki67-positive tumor cells, while hsa-miR-342-3p levels were inversely correlated with tumor staging. Analysis of the expression levels of miRs in serum exosomes from breast cancer patients has the potential to identify new, non-invasive, blood-borne prognostic molecular markers to predict the potential for brain metastasis in breast cancer. Additional functional analyzes and careful validation of the identified markers are required before their potential future diagnostic use.

[Postpartum hemorrhage : Interdisciplinary consideration in the context of patient blood management]. / Postpartale Hämorrhagie : Interdisziplinäre Betrachtung im Kontext des Patient Blood Management.

Postpartum hemorrhage (PPH) nowadays still represents a severe complication of both a vaginal delivery and a cesarean section. In German-speaking areas a new definition of the term has recently become established and the nomenclature with respect to the severe form of PPH was dropped. The handling of misoprostol as a uterotonic during treatment of PPH is also new, which is available in Germany only as a medical direct import. For adequate diagnostics and targeted treatment interdisciplinary and standardized algorithms should be established and the specialist disciplines involved should be sensitized to this problem. In addition to an adequate hemostasis, a developing coagulopathy must be recognized at an early stage and treated with targeted coagulation management. Through implementation concepts, particularly the second pillar (minimization of blood loss) and the third pillar (rational use of blood transfusions) of patient blood management, various aspects for improvement of treatment of a PPH can be identified.

[Patient blood management in the preparation for birth, obstetrics and postpartum period]. / Patient Blood Management in der Geburtsvorbereitung, Geburtshilfe und postpartalen Phase.

The implementation of patient blood management (PBM) is increasingly becoming standard in operative medicine. Recently, interest has also been shown for the vulnerable collective of pregnant women and neonates. As the information regarding anesthesiological procedures for pregnant women and the peripartum period including an informed consent process should be carried out long before childbirth, this provides a good possibility in this connection to incorporate PBM. An anesthesiological risk estimation as well as the diagnostic workup and treatment of potential anemia should be carried out during the pregnancy. Furthermore, loss of blood in anticipation of bleeding complications should be reduced by interdisciplinary preventive measures and an individually coordinated postpartum care should be organized. This results in an early diagnosis of anemia or iron deficiency with subsequent treatment also postpartum, analogous to the prepartum period.

Disparities in accessibility to evidence-based breast cancer care facilities by rural and urban areas in Bavaria, Germany.

BACKGROUND: Breast cancer (BC), which is most common in elderly women, requires a multidisciplinary and continuous approach to care. With demographic changes, the number of patients with chronic diseases such as BC will increase. This trend will especially hit rural areas, where the majority of the elderly live, in terms of comprehensive health care. METHODS: Accessibility to several cancer facilities in Bavaria, Germany, was analyzed with a geographic information system. Facilities were identified from the national BC guideline and from 31 participants in a proof-of-concept study from the Breast Cancer Care for Patients With Metastatic Disease registry. The timeframe for accessibility was defined as 30 or 60 minutes for all population points. The collection of address information was performed with different sources (eg, a physician registry). Routine data from the German Census 2011 and the population-based Cancer Registry of Bavaria were linked at the district level. RESULTS: Females from urban areas (n = 2,938,991 [ie, total of females living in urban areas]) had a higher chance for predefined accessibility to the majority of analyzed facilities in comparison with females from rural areas (n = 3,385,813 [ie, total number of females living in rural areas]) with an odds ratio (OR) of 9.0 for cancer information counselling, an OR of 17.2 for a university hospital, and an OR of 7.2 for a psycho-oncologist. For (inpatient) rehabilitation centers (OR, 0.2) and genetic counselling (OR, 0.3), women from urban areas had lower odds of accessibility within 30 or 60 minutes. CONCLUSIONS: Disparities in accessibility between rural and urban areas exist in Bavaria. The identification of underserved areas can help to inform policymakers about disparities in comprehensive health care. Future strategies are needed to deliver high-quality health care to all inhabitants, regardless of residence.

The effects of the COVID-19 pandemic on psychological stress in breast cancer patients.

BACKGROUND: The majority of breast cancer patients are severely psychologically affected by breast cancer diagnosis and subsequent therapeutic procedures. The COVID-19 pandemic and associated restrictions on public life have additionally caused significant psychological distress for much of the population. It is therefore plausible that breast cancer patients might be particularly susceptible to the additional psychological stress caused by the pandemic, increasing suffering. In this study we therefore aimed to assess the level of psychological distress currently experienced by a defined group of breast cancer patients in our breast cancer centre, compared to distress levels pre-COVID-19 pandemic. METHODS: Female breast cancer patients of all ages receiving either adjuvant, neoadjuvant, or palliative therapies were recruited for the study. All patients were screened for current or previous COVID-19 infection. The participants completed a self-designed COVID-19 pandemic questionnaire, the Stress and Coping Inventory (SCI), the National Comprehensive Cancer Network® (NCCN®) Distress Thermometer (DT), the European Organization for Research and Treatment of Cancer (EORTC) QLQ C30, and the BR23. RESULTS: Eighty-two breast cancer patients were included. Therapy status and social demographic factors did not have a significant effect on the distress caused by the COVID-19 pandemic. The results of the DT pre and during COVID-19 pandemic did not differ significantly. Using the self-designed COVID-19 pandemic questionnaire, we detected three distinct subgroups demonstrating different levels of concerns in relation to SARS-CoV-2. The subgroup with the highest levels of concern reported significantly decreased life quality, related parameters and symptoms. CONCLUSIONS: This monocentric study demonstrated that the COVID-19 pandemic significantly affected psychological health in a subpopulation of breast cancer patients. The application of a self-created "COVID-19 pandemic questionnaire" could potentially be used to help identify breast cancer patients who are susceptible to increased psychological distress due to the COVID-19 pandemic, and therefore may need additional intensive psychological support.

[Early and Late Toxicities and Socio-Medical Relevant Disorders after Oncological Treatment for Breast Cancer-Implications and Assessment of Rehabilitation Requirement]. / Früh- und Spättoxizitäten sowie sozialmedizinisch-relevante Folgestörungen bei Brustkrebs-Patientinnen als Basis der Abschätzung des Reha-Bedarfes.

INTRODUCTION: Reasonable to the improved prognosis of breast cancer (BC) long-term toxicities and side effects of oncological therapy gain more importance for work ability and social life of BC patients. Aim of this study was the analysis of occurence and differences of treatment-related side effects in relation to type of rehabilitation (so-called AHB vs. later rehabilitation) after therapy for BC. METHODS: Clinical and patient related data as early and late toxicities after oncological treatment of 8.000 patients with BC (55.7±10.4y) were analyzed and compared with current literature. RESULTS: In 23.9% a mastectomy was performed, in 87.3% radiotherapy. In most cases an additional systemic treatment (57,6% CTX, 15,1% anti-Her2, 71% antihormonal treatment) was carried out. In 8.1% women suffered from recurrent or metastatic BC. As most common side effects of multimodal treatment weakness/fatigue (73,6%), insomnia (51,9%), CIPN (33%), lymph edema (13,9%) and drug-induced arthralgia (24,8%) were detected. In addition, 60.4% of women reported high levels of psychological distress. Shortly after therapy typical side effects were drug-induced toxicities (Leucopenia, p<0.0001; anemia, p<0.001; weakness/fatigue p<0.001; CIPN, p<0.0001), whereas in a later course chronic lymphedema (p<0.0001), chronic or recurrent disease (p<0.0001), status after mastectomy (p<0.0001) and psychological distress (p<0.0001) were significantly more often seen. Moreover, in this collective patients were significantly younger (53,7±9,8 vs. 56,3±10,7y). CONCLUSIONS: In BC patients, significantly different impairments and toxicities were documented between patients with early rehabilitation and patients with later onset of rehabilitation. These data may help to establish more individual and focused rehabilitation concepts in specialized centers.

[Ethical, Psychosocial and Legal Aspects of the Treatment of Pregnant Patients with Brain Death]. / Ethische, psychosoziale und rechtliche Aspekte der Behandlung hirntoter Schwangerer.

The therapy of brain-dead pregnant women is an extreme example not only of the possibilities in current critical care, but also of resulting ethical, social and legal controversies, an area not familiar to most clinicians. Based on the case of a patient with fatal traumatic brain injury, a previously unknown early pregnancy and stated will to donate organs, we will discuss several aspects using published case reports: therapeutic goals, especially palliative care vs. continuation; implications of brain death diagnosis; considerations on legal care; involvement of relatives, especially the child's father; dynamics within the care team; and finally the issue of putative organ donation. This complex case once more depicts that even facing such highly unfavourable framework and seemingly irreconcilable factors, pregnancy can prevail. The researched facts and considerations in this article are intended to give an overview of potential dilemmas and might serve as a starting point in similar situations.
