ABSTRACT

Li-Fraumeni syndrome (LFS) is a rare autosomal dominant cancer predisposition syndrome associated with a highly elevated lifetime cancer risk. This and the recommended intense surveillance program represent a large psychological burden on families. In order to develop targeted psychosocial interventions, we conducted a needs assessment. Adults (≥18 years) with LFS were included via regular hospital visits and online support groups and newsletters. Individuals filled out a questionnaire addressing among others: fear of progression (FoP-questionnaire, short-form), health-related quality of life (HRQoL, Short-Form Health Survey-12), distress (National Comprehensive Cancer Network distress thermometer), perceived cancer risk, and aspects of surveillance adherence. Collecting data over a 14-month period (March 2020 - June 2021), 70 adults were recruited (female = 58, 82.9%; mean age = 41.53 years). With mean mental component scores (MCS) of 42.28 (SD = 10.79), and physical component scores (PCS) of 48.83 (SD = 10.46), HRQoL was low in 34.8% (physical) and 59.4% (mental) of individuals when applying a mean cut-off of 45.4 (PCS) and 47.5 (MCS) to indicate poor HRQoL. High levels of FoP and distress were present in 68.6% and 69.1% of the participants, respectively. Performing a multiple linear regression on MCS and PCS, no sociodemographic variable was shown to be significant. FoP (ß = -0.33, p < 0.05) and distress (ß = -0.34, p < 0.05) were significantly associated with MCS. Individuals in our sample were burdened more than expected, with the majority reporting low levels of (mental) HRQoL, high distress, and FoP. Psychosocial support is necessary to help individuals with LFS (survivors as well as "previvors") increase their HRQoL, as it is crucial to survival.

ABSTRACT

PURPOSE: Individuals with cancer predisposition syndromes (CPS) inherit elevated cancer risks. Medical supply gaps for people at risk of CPS cause insufficient outreach and miss potential benefits of individualized care strategies. Increased awareness of CPS and progress in the eHealth sector are untapped sources of health care improvement for affected individuals. METHODS AND RESULTS: This study addressed German-speaking medical students with an online questionnaire in respect to their knowledge of CPS, their medical education, and perspectives. The study population (n = 404) reported interest in and knowledge of CPS, supported by a satisfactory and sustainable education for their prospective patient care. The next generation of doctors would implement eHealth to improve medical services. Skepticism about digitization was claimed by students. They were especially concerned about deterioration in the physician-patient relationship, data abuse, dependence on technology, and incorrect diagnoses. CONCLUSION: Due to increasing diagnosing of CPS and deeper knowledge, this topic is essential for the curriculum in medical schools. In particular, care providers need know-how on identifying patients at risk for a CPS, certain diagnostic and therapeutic steps, surveillance and prophylactic strategies to improve patients' outcomes. Education in medical school as well as implemented eHealth seems to have potential to meet this demand in an upcoming era of personalized medicine. What does this study add to the clinical work. Medical teaching on cancer predisposition syndromes should be expanded to improve knowledge and individualized and personalized healthcare.

ABSTRACT

BACKGROUND: Although breast cancer (BC) has a high survival rate, relapse events may occur which ultimately lead to aggressive disease. Circulating cell-free microRNAs (cf-miRNAs) are a promising minimally invasive biomarker with diagnostic and/or prognostic potential. Unfortunately, there is still no consensus as to a universal cf-miRNA biomarker in BC and there has been no clinical implementation until now. One major limitation is the technical variation with cf-miRNA isolation and specific quantification methods. METHODS: In this study, we assessed the total levels of cf-miRNAs as a potential prognostic marker for BC in 356 plasma samples from 250 BC patients. RESULTS: High levels of cf-miRNAs significantly correlated with unfavourable clinical features including tumour stage, load and the presence of metastasis at diagnosis. With more than 9 years of follow-up, we could show that global cf-miRNA levels significantly correlated with cancer relapse which was confirmed in multivariate cox regression analysis. Finally, for a subset of patients where the serial plasma was available, levels of cf-miRNAs increased in the plasma prior to clinical detection of progressive disease and were massively elevated in patients who died compared to those still alive at the last timepoint of measurement. CONCLUSIONS: This is the first study to suggest that total cf-miRNA levels in the blood can be used as an independent prognostic marker for BC.

ABSTRACT

BACKGROUND: Ovarian cancer (OC) is an aggressive disease, primarily diagnosed in late stages with only 20% of patients surviving more than 5 years after diagnosis. There is a pending need to improve current diagnostics and prognostics. METHODS: In this study, we investigated total circulating cell-free microRNA (cf-miRNA) levels as well as a panel of cf-miRNAs in the plasma of OC patients (n = 100), patients with benign lesions (n = 45) and healthy controls (n = 99). RESULTS: High levels of cf-miRNAs correlated with unfavourable clinical features and were an independent prognosticator of patient survival. By mining NGS data, we identified a signature panel of seven individual cf-miRNAs which could distinguish controls from benign cases with an AUC of 0.77 and controls from cancer cases with an AUC of 0.87. Importantly, in combination with the current gold-standard marker, CA-125, the panel could predict early OC with an AUC of 0.93. CONCLUSION: Our findings highlight the potential of cf-miRNA levels as well as individual cf-miRNAs for OC diagnosis and prognosis that warrants further clinical evaluation.

ABSTRACT

Comparably little is known about breast cancer (BC) risks in women from families tested negative for BRCA1/2 mutations despite an indicative family history, as opposed to BRCA1/2 mutation carriers. We determined the age-dependent risks of first and contralateral breast cancer (FBC, CBC) both in noncarriers and carriers of BRCA1/2 mutations, who participated in an intensified breast imaging surveillance program. The study was conducted between January 1, 2005, and September 30, 2017, at 12 university centers of the German Consortium for Hereditary Breast and Ovarian Cancer. Two cohorts were prospectively followed up for incident FBC (n = 4,380; 16,398 person-years [PY], median baseline age: 39 years) and CBC (n = 2,993; 10,090 PY, median baseline age: 42 years). Cumulative FBC risk at age 60 was 61.8% (95% CI 52.8-70.9%) for BRCA1 mutation carriers, 43.2% (95% CI 32.1-56.3%) for BRCA2 mutation carriers and 15.7% (95% CI 11.9-20.4%) for noncarriers. FBC risks were significantly higher than in the general population, with incidence rate ratios of 23.9 (95% CI 18.9-29.8) for BRCA1 mutation carriers, 13.5 (95% CI 9.2-19.1) for BRCA2 mutation carriers and 4.9 (95% CI 3.8-6.3) for BRCA1/2 noncarriers. Cumulative CBC risk 10 years after FBC was 25.1% (95% CI 19.6-31.9%) for BRCA1 mutation carriers, 6.6% (95% CI 3.4-12.5%) for BRCA2 mutation carriers and 3.6% (95% CI 2.2-5.7%) for noncarriers. CBC risk in noncarriers was similar to women with unilateral BC from the general population. Further studies are needed to confirm whether less intensified surveillance is justified in women from BRCA1/2 negative families with elevated risk.

ABSTRACT

BACKGROUND: Li-Fraumeni syndrome (LFS) is a high-risk cancer predisposition syndrome caused by pathogenic germline variants of TP53. Cancer surveillance has noted a significant survival advantage in individuals with LFS; however, little is known about the feasibility, acceptance, and psychosocial effects of such a program. METHODS: Pathogenic TP53 germline variant carriers completed a 7-part questionnaire evaluating sociodemographics, cancer history, surveillance participation, reasons for nonadherence, worries, and distress adapted from the Cancer Worry Scale. Counselees' common concerns and suggestions were assessed in MAXQDA Analytics Pro 12. RESULTS: Forty-nine participants (46 females and 3 males), aged 40.0 ± 12.6 years, formed the study population; 43 (88%) had a personal cancer history (including multiple cancers in 10 [20%]). Forty-three individuals participated (88%) in surveillance during the study or formerly. Willingness to undergo surveillance was influenced by satisfaction with genetic testing and counseling (P = .019 [Fisher-Yates test]) but not by sociodemographics, cancer history, or distress level. Almost one-third of the participants reported logistical difficulties in implementing surveillance because of the high frequency of medical visits, scheduling difficulties, and the travel distance to their surveillance providers. Self-reported distress and perceived emotional burden for family members and partners were moderate (median for self-reported distress, 3.3; median for perceived emotional burden, 3.0). For both, the interquartile range was moderate to very high (2.7-3.7 and 3.0-3.7, respectively). CONCLUSIONS: Individuals with LFS require efficient counseling as well as an accessible, well-organized, interdisciplinary, standardized surveillance program to increase adherence and psychological coping.

ABSTRACT

PURPOSE: To explore the ability of intraoperative specimen radiography (SR) to correctly identify positive margins in patients receiving breast conserving surgery (BCS). To assess whether the reoperation rate can be reduced by using this method. METHODS: This retrospective study included 470 consecutive cases receiving BCS due to a primarily diagnosed breast cancer. SR was carried out in two planes, assessing the specimen regarding the presence of the lesion and its relation to all margins. If indicated, re-excision of selective orientations was advised. Under consideration of gross inspection and the SR-findings, it was up to the surgeon whether to perform re-resections. The recommendations for re-excision were, separately for each orientation, compared to the histopathological results, serving as gold standard. RESULTS: Intraoperative SR was performed in 470 cases, thus 2820 margins were assessed. Of those, 2510 (89.0%) were negative and 310 (11.0%) positive. SR identified 2179 (77.3%) margins correctly as negative, whereas 331 (11.7%) clear margins were misjudged as positive. Of 310 infiltrated margins, SR identified 114 (4.0%) correctly, whereas 196 (7.0%) infiltrated margins were missed. This resulted in a sensitivity/specificity of 36.8%/86.8% and PPV/NPV of 25.6%/91.8%. Through targeted re-resections positive margins could be reduced by 31.0% [310 to 214 (7.6%)]. On case level, the rate of secondary procedures could be reduced by 37.0% [from 162 to 102 (21.7%)]. CONCLUSIONS: SR is a helpful tool to identify infiltrated margins and to reduce the rate of secondary surgeries by recommending targeted re-excisions of according orientations in order to obtain a final negative margin status.

ABSTRACT

PURPOSE: The application of amide proton transfer (APT) CEST MRI for diagnosis of breast cancer is of emerging interest. However, APT imaging in the human breast is affected by the ubiquitous fat signal preventing a straightforward application of existing acquisition protocols. Although the spectral region of the APT signal does not coincide with fat resonances, the fat signal leads to an incorrect normalization of the Z-spectrum, and therefore to distorted APT effects. In this study, we propose a novel normalization for APT-CEST MRI that corrects for fat signal-induced artifacts in the postprocessing without the need for application of fat saturation schemes or water-fat separation approaches. METHODS: The novel normalization uses the residual signal at the spectral position of the direct water saturation to estimate the fat contribution. A comprehensive theoretical description of the normalization for an arbitrary phase relation of the water and fat signal is provided. Functionality and applicability of the proposed normalization was demonstrated by in vitro and in vivo experiments. RESULTS: In vitro, an underestimation of the conventional APT contrast of approximately -1.2% per 1% fat fraction was observed. The novel normalization yielded an APT contrast independent of the fat contribution, which was also independent of the water-fat phase relation. This allowed APT imaging in patients with mamma carcinoma corrected for fat signal contribution, field inhomogeneities, spillover dilution, and water relaxation effects. CONCLUSION: The proposed normalization increases the specificity of APT imaging in tissues with varying fat content and represents a time-efficient and specific absorption rate-efficient alternative to fat saturation and water-fat separation approaches.

ABSTRACT

PURPOSE: General conditions in the health-care system in Germany have changed dramatically in recent years. Factors affecting this include above all demographic change, rapid developments in diagnostic and therapeutic options, and the application of economic criteria to the health-care sector. This study aimed to establish the current status quo regarding conditions of work and training for young doctors in gynecology and obstetrics, analyze stress factors, and suggest potential improvements. METHODS: Between October 2015 and March 2016, a web-based survey was carried out among residents and members of the German Society for Gynecology and Obstetrics. The electronic questionnaire comprised 65 items on seven topics. Part of the survey included the short version of a validated model of professional gratification crises for analyzing psychosocial work-related stress. RESULTS: The analysis included a total of 391 complete datasets. Considerable negative findings in relation to psychosocial work pressure, time and organizational factors, quality of specialty training, and compatibility between work and family life and work and academic tasks were detected. A high level of psychosocial work pressure is associated with more frequent job changes, reduced working hours, poorer health among physicians, and a lower subjectively assessed quality of care. CONCLUSIONS: Greater efforts are needed from all the participants involved in patient care to achieve high-quality training and working conditions that allow physicians to work in a healthy and effective way. These aspects are all prerequisites for sustainably maximizing the resource "physician" and for ensuring high-quality patient care.

ABSTRACT

PURPOSE: Psychosocial and biological factors influence the perception of physical changes during pregnancy. Some pregnant women present to the obstetric emergency department (ED) with diverse symptoms not requiring urgent medical action. These visits result in over-consultation, tying up resources and inflating health care expenses. This study outlines factors associated with multiple ED visits during pregnancy, measures the prevalence of anxiety and depression, and explores the choice of maternity clinic for delivery aiming to elucidate options for care strategies. METHODS: This prospective, cross-sectional, questionnaire-based bicentric study was performed in the obstetric outpatient departments of two university hospitals in Germany and recruited pregnant women between 12/2016 and 11/2017. The questionnaire included socio-demographics, obstetric history, anxiety (GAD-7), depression (PHQ-9), and health status (WHO-5, SF-12). RESULTS: This analysis included 496 women and showed that women with numerous ED visits were significantly younger (p < 0.0001), less educated (p = 0.0002), and more likely to be unemployed and single. Different prevalences for anxiety and depression were detected correlating with the number of ED visits although each showing only low effect sizes (0.024 resp. 0.015). CONCLUSIONS: Pregnant women attending the ED more often might benefit from health education, psychosomatic interventions, and social support to overcome their depression and anxiety to avoid non-urgent ED consultations. Further prospective studies are needed to support these findings.

ABSTRACT

OBJECTIVE: The working and training conditions of young physicians in Germany have changed over the last few years, as a result of far-reaching changes in the healthcare system. Therefore, Germany-wide surveys among young physicians of several disciplines were evaluated in a pooled analysis, in order to obtain a current interdisciplinary impression of conflicts in their daily work. MATERIAL AND METHODS: Data from web-based surveys from residents training in six disciplines were analyzed together retrospectively. One focus was a gratification crises model for the assessment of psychosocial workload. RESULTS: Data on 4041 participants were evaluated. In day-to-day work, young physicians were burdened with a high proportion of tasks that were not directly medical. Instruments of good subspecialty training, such as training contracts, curricula and regular feedback were associated with a lower psychosocial workload, which was generally significant among the participants. An economic influence on medical-professional decisions was subjectively clearly present among the participants. CONCLUSION: Many young doctors find the current work and training conditions in the medical work environment unsatisfactory. This might have consequences not only for the doctors themselves, but also for the patients they care for. A healthy work environment with health professionals in good health is therefore crucial and should be in everyone's interest.

ABSTRACT

In recent years, metabolites have attracted substantial attention as promising novel biomarkers of various diseases. However, breast cancer plasma metabolite studies are still in their infancy. Here, we investigated the potential of metabolites to serve as minimally invasive, early detection markers of primary breast cancer. We profiled metabolites extracted from the plasma of primary breast cancer patients and healthy controls using tandem mass spectrometry (UHPLC-MS/MS and FIA-MS/MS). Two metabolites were found to be upregulated, while 16 metabolites were downregulated in primary breast cancer patients compared to healthy controls in both the training and validation cohorts. A panel of seven metabolites was selected by LASSO regression analysis. This panel could differentiate primary breast cancer patients from healthy controls, with an AUC of 0.87 (95% CI: 0.81 ~ 0.92) in the training cohort and an AUC of 0.80 (95% CI: 0.71 ~ 0.87) in the validation cohort. These significantly differentiated metabolites are mainly involved in the amino acid metabolism and breast cancer cell growth pathways. In conclusion, using a metabolomics approach, we identified metabolites that have potential value for development of a multimarker blood-based test to complement and improve early breast cancer detection. The panel identified herein might be part of a prescreening tool, especially for younger women or for closely observing women with certain risks, to facilitate decision making regarding which individuals should undergo further diagnostic tests. In the future, the combination of metabolites and other blood-based molecular marker sets, such as DNA methylation, microRNA, and cell-free DNA mutation markers, will be an attractive option.

ABSTRACT

BACKGROUND: Dental and cervical controls are two established screening programs in Germany. Compliance to orthodontic treatment in childhood is essential for dental health and one of the first health interventions that requires adherent behavior; therefore, it may be associated with participation in further screening programs in adulthood. However, it is not yet known whether early orthodontic treatment influences long-term screening adherence. METHODS: Using a questionnaire administered during a visit to a special dysplasia outpatient service, this case-control study evaluated women's personal history of orthodontic care, long-term satisfaction, and dental and gynecological screening adherence. Oral health status and dental anxiety were assessed with validated instruments. Cases were categorized as cervical dysplasia only (S2) or cervical dysplasia with conization (S1) and compared to healthy controls with a normal PAP smear. RESULTS: A study population of 233 participants included 132 cases and 101 controls. The control group had had orthodontic treatment during childhood more often than our study population with abnormal PAP smears (68.3% controls versus 56.1% subjects; p < 0.005). Orthodontic treatment was not associated with attending dental appointment or gynecological check-ups. However, women with an orthodontic treatment in childhood were significantly more often vaccinated against human papillomavirus than women without orthodontic treatment (p < 0.03). CONCLUSION: Data suggest that women with orthodontic treatment in childhood are more conscious about prevention strategies in adulthood; therefore, compliant behavior might be established in childhood.

ABSTRACT

PURPOSE: Annual cervical cancer screening is recommended in Germany as a part of the statutory preventive care. Abnormal results can provoke psychological distress and anxiety, compromising women's adherence. Little is known about how a cervical dysplasia impacts adherence follow-up visits and prevention habits over time. To optimize care strategies, this study aims to identify women at risk for nonadherence to follow-up visits after a screening event. METHODS: Between November 2015 and May 2017, participants with an abnormal Pap smear at the Heidelberg and Leipzig University Hospitals received a four-part questionnaire (sociodemographic data, PHQ-D, self-designed fear and prevention habit questions) at the first consultation (T1) and subsequently after 3 (T2) and 6 (T3) months; healthy controls completed the questionnaire at T1. RESULTS: 132 women with an abnormal Pap smear [with conization: S1 (n = 68, 51.5%), without intervention: S2 (n = 64, 48.5%)] and healthy controls (K, n = 101) generally adhered to gynecological checkups, except S1 6 months after the first diagnosis (S1/T3 - 0.47, signed rank p < 0.0005). Knowledge of primary prevention information, i.e., HPV vaccination, was significantly higher among K (K 58%, S1 29%, S2 44%, Chi-squared p = 0.01) as was vaccine uptake (K 39% versus S1/S2 7% and 17%, respectively, Chi-squared p = 0.0004). Fear of upcoming Pap smears rose significantly over time (S1/T1-S1/T2-S1/T3, Wilcoxon signed-rank test p < 0.001) and was higher among those with conization at T2 (Chi-square test, p = 0.01) and partially accompanied by panic disorders at T1 (Chi-square test p = 0.035). Realization of general preventive habits rose significantly among women without an operative procedure (S2) over the study. CONCLUSION: This study advances the understanding of non-participation in follow-up visits after a dysplasia diagnosis, identifying post-conization women as a special risk group for decreased adherence.

ABSTRACT

In the last decade, circulating nucleic acids such as microRNAs (miRNAs) and cell-free DNA (cfDNA) have become increasingly important in serving as potential novel biomarkers for a variety of human diseases. If cell-free nucleic acids are to become routinely used in diagnostics, the difference in plasma miRNA and cfDNA levels between healthy and diseased subjects must exceed pre-analytical and analytical variability. Until now, few studies have addressed the time limitations of pre-processing or explored the potential use of long-term blood storage tubes, which might need to be implemented in real-life diagnostics. In this study, we analyzed the stability of four breast cancer-associated miRNAs and two cancer-associated genes under various storage conditions, to test their limitations for potential application in clinical diagnostics. In two consecutive experiments, we tested the limits of conventional EDTA tubes, as well as long-term storage blood collection tubes (BCTs) from four different manufacturers. We found that circulating miRNAs are relatively stable when stored in EDTA monovettes for up to 12 h before processing. When stored in BCTs, circulating miRNAs and cfDNA are stable for up to 7 days, depending on the manufacturer. Norgen tubes were superior for cfDNA yield, while Streck tubes performed the worst in our study with hemolysis induction. In conclusion, plasma prepared from whole blood is suitable for the quantification of both cf-miRNAs and cfDNA simultaneously.

ABSTRACT

PURPOSE: Non-invasive blood-based molecular markers have been investigated for cancer diagnosis and prognosis. Circulating free or cell-free DNA (cfDNA) variables have been shown to be putative markers in breast cancer prognosis. METHODS: Here, we investigated the potential prognostic ability of cfDNA concentration and cfDNA integrity (cfDI) in a study cohort of 268 patients by quantitative PCR. We compared cfDNA concentration and cfDI at baseline and after one cycle of therapy in metastatic breast cancer (MBC) patients. RESULTS: A significantly increased cfDI (P = 1.21E-7 for ALU and P = 1.87E-3 for LINE1) and decreased cfDNA concentration (P = 1.17E-3 for ALU and P = 1.60E-2 for LINE1) in both repetitive DNA elements after one cycle of therapy was observed. A multiple Cox regression model indicated that cfDI and cfDNA concentration can serve as independent prognostic markers in patients at baseline with HR (95% CI) of 0.70 (0.48-1.01) for ALU cfDI, 0.63 (0.44-0.92) for LINE1 cfDI, 2.44 (1.68-3.53) for ALU cfDNA concentration, and 2.12 (1.47-3.06) for LINE1 cfDNA concentration and after one cycle of therapy with HR (95% CI) of 0.59 (0.42-0.84) for ALU cfDI, 0.51 (0.36-0.74) for LINE1 cfDI, 1.59 (1.31-1.92) for ALU cfDNA concentration, and 1.30 (1.17-1.45) for LINE1 cfDNA concentration, respectively. By comparing integrated prediction error of different models, cfDNA variables were shown to improve the prognostic power of the CTC status. CONCLUSIONS: We hereby show that cfDNA variables, especially in combination with other markers, can serve as attractive prognostic markers for MBC patients at baseline and during the systematic therapy.

ABSTRACT

BACKGROUND: In general surgery, minimally invasive laparoscopic procedures have been steadily increasing over the last decade. The application of advanced bipolar and ultrasonic energy devices for sealing and cutting of blood vessels plays a vital role in routine clinical procedures. The advantages of energy-based instruments are enhanced sealing capability combined with both fast sealing time and minimal thermal injury. The purpose of this study was to compare the safety and efficacy profiles of nine laparoscopic sealing and cutting devices in a porcine model, with a new scoring system. METHODS: Comparative studies in a porcine model were performed to assess vessel sealing, burst pressure, thermal spread, maximum heat, sealing/cooling time, and compression strength over the full jaw. Nine different devices from five manufacturers were tested in this study. The sealing and cutting devices (SCD) score has been developed to enable standardized comparisons of various devices. For this purpose, the most important parameters were identified through a consensus approach. RESULTS: All sealed vessels with different devices could withstand a median pressure of more than 300 mmHg (range 112-2046 mmHg). The time for the sealing procedure was 7.705 s (range 5.305-18.38 s) for the ultrasonic and 7.860 s (range 5.08-10.17 s) for the bipolar devices. The ultrasonic instruments reached a median temperature of 218.1 °C (range 81.3-349.75 °C) and the bipolar devices a temperature of 125.5 °C (range 94.1-133.35 °C). The tissue reached a median temperature of 61.9 (range 47.1-80.6 °C) after ultrasonic sealing and 76.7 °C (range 63.1-94.2 °C) after bipolar sealing. The median SCD score was 10.47 (range 7.16-13.72). CONCLUSION: All the instruments used seemed safe for use on the patient. The SCD score allows an indirect comparability of the instruments.

ABSTRACT

PURPOSE: Reduction of maternal morbidity and mortality is a major worldwide objective anchored in the millennium goals of the United Nations. To improve fetal and maternal care, a constant attempt to discover groundbreaking technologies is ongoing. One approach is the enhancement of non-invasive fetal ECG devices. Most importantly, acceptance of new technologies by pregnant women is a prerequisite for successful implementation. METHODS: This questionnaire-based study conducted at the University Hospital Heidelberg, Germany between May and June 2017 evaluates pregnant women's attitudes towards a new device for fetal ECG monitoring and its potential home usage. The study population was questioned after exposure to the Parides/Atlantis prototype (Nemo Healthcare, Veldhoven, The Netherlands), whereas the maternal and gestational age-matched control group was left to envision telemedical topics. RESULTS: The prototype and its potential usage in a clinical and telemedical setting was highly accepted, and its comfort and appearance satisfied participants. Its use caused significantly improved telemedical understanding as envision increased (p = 0.0015). Implementation and integration of telemedical devices into antenatal care was significantly preferred by the study group (p = 0.0011), though participants desire more specific features for their personal use. Optional home-based self-monitoring to reduce scheduled doctoral visits (p = 0.0004) as well as self-assessment prior to self-initiated, unscheduled consultation (p < 0.0001) could be affected positively by such a device. Furthermore, it could reduce face-to-face interaction with the care provider (p = 0.0163). CONCLUSIONS: The positive feedback on remote self-monitoring might open options for a more "patient as partners" oriented prenatal care in the future. Safety and reliability remain a major issue. More comprehensive studies with new technologies are needed to diligently ensure quality of care. Finally, results for new technologies must be communicated to pregnant women for their acceptance and usage of new devices.

ABSTRACT

PURPOSE: In this case-control study, the impact on quality of life and sexual function in women with cervical dysplasia and conization will be evaluated, in order to address coping with such a premalignant lesion and to improve strategies for salutogenesis. METHODS: This multicenter case-control study evaluates women at special dysplasia outpatient clinic (T1) as well as 3 (T2) and 6 (T3) months after the diagnosis of a dysplasia. The women were subgrouped upon dysplasia only (S2) or dysplasia with conization (S1). Sexual function as well as cervix-related and general quality of life was assessed using validated instruments (FSFI-d, EORTC-QLQ-CX24, SF-36). RESULTS: Women with dysplasia had a lower sexual functioning than controls (FSFI: S1: 23.8 ± 9.7 (p < 0.003); S2: 25.3 ± 7.5 (p < 0.03); K: 29.1 ± 4.5) as well as a lower physical component score (SF-36: S1: 51.3 ± 8.6 (p < 0.02); S2: 51.7 ± 7.8 (p < 0.05); K: 54.2 ± 6.6) and had a significantly reduced body image (EORTC-QLQ-CX24: S1: 75.7 (p < 0.001); S2: 76.5 (p < 0.001), K:89.2). Sexual functioning was not affected by conization in the observational period over 6 months; however, sexual worry was impacted. Over temporal progression women who underwent conization worried more. Regression analysis revealed a cervical dysplasia to impact sexual function. CONCLUSION: Data suggest that women with the diagnosis of a cervical dysplasia are impaired in their sexual function as well as general and cervix-related quality of life, mostly independent of conization or further observation. To improve salutogenesis in the long run, the communication on dysplasia and its treatment strategy at the beginning, as well as part of aftercare, or psychosomatic intervention, might be treatment options for women at risk.

ABSTRACT

PURPOSE: Breast cancer is the leading cause of death from cancer in women and the most common cancer in the world [1]. To date, many patients with estrogen-receptor-positive (ER+) breast cancer are overtreated with chemotherapy when the rationale for adjuvant chemotherapy is based on clinicopathologic parameters. Different studies were able to demonstrate that a 21-gene expression assay (Oncotype DX® Genomic Health, Redwood City, CA) can predict the benefit from adjuvant chemotherapy in ER+ breast cancers [2, 3] and provide additional prognostic information independent of clinicopathological features [4]. RESULTS: Data from all patients with ER+ Her2neu- breast cancer undergoing Oncotype DX® testing between 2011 and 2014 at a tertiary referral center in Germany were analyzed. Oncotype DX® was performed in 69 cases, in 2 cases data were missing and in 3 cases Oncotype DX® could not be performed by the company. The results showed a low risk in 39 cases, an intermediate risk in 22 cases and a high risk in 3 cases. Based on Oncotype results, treatment recommendations were changed in 39 of 64 patients (61%). Before Oncotype DX® testing, chemotherapy was recommended in 67 patients, afterwards only in 25 patients. Data from 44 of 67 patients were matched to controls for stage, tumor grade, menopausal and hormone receptor status. Within a mean observation time of 19.7 months, cancer recurrence was observed in two patients. CONCLUSIONS: Oncotype DX® testing can be recommended for risk-tailored chemotherapy. Results should be validated in larger prospective studies.
