RESUMEN

Summary The S3-guideline on endometrial cancer, first published in April 2018, was reviewed in its entirety between April 2020 and January 2022 and updated. The review was carried out at the request of German Cancer Aid as part of the Oncology Guidelines Program and the lead coordinators were the German Society for Gynecology and Obstetrics (DGGG), the Gynecology Oncology Working Group (AGO) of the German Cancer Society (DKG) and the German Cancer Aid (DKH). The guideline update was based on a systematic search and assessment of the literature published between 2016 and 2020. All statements, recommendations and background texts were reviewed and either confirmed or amended. New statements and recommendations were included where necessary. Aim The use of evidence-based risk-adapted therapies to treat women with endometrial cancer of low risk prevents unnecessarily radical surgery and avoids non-beneficial adjuvant radiation therapy and/or chemotherapy. For women with endometrial cancer and a high risk of recurrence, the guideline defines the optimum level of radical surgery and indicates whether chemotherapy and/or adjuvant radiation therapy is necessary. This should improve the survival rates and quality of life of these patients. The S3-guideline on endometrial cancer and the quality indicators based on the guideline aim to provide the basis for the work of certified gynecological cancer centers. Methods The guideline was first compiled in 2018 in accordance with the requirements for S3-level guidelines and was updated in 2022. The update included an adaptation of the source guidelines identified using the German Instrument for Methodological Guideline Appraisal (DELBI). The update also used evidence reviews which were created based on selected literature obtained from systematic searches in selected literature databases using the PICO process. The Clinical Guidelines Service Group was tasked with carrying out a systematic search and assessment of the literature. Their results were used by interdisciplinary working groups as a basis for developing suggestions for recommendations and statements which were then modified during structured online consensus conferences and/or additionally amended online using the DELPHI process to achieve a consensus. Recommendations Part 1 of this short version of the guideline provides recommendations on epidemiology, screening, diagnosis, and hereditary factors. The epidemiology of endometrial cancer and the risk factors for developing endometrial cancer are presented. The options for screening and the methods used to diagnose endometrial cancer are outlined. Recommendations are given for the prevention, diagnosis, and therapy of hereditary forms of endometrial cancer. The use of geriatric assessment is considered and existing structures of care are presented.

RESUMEN

PURPOSE: Guidelines recommend a structured symptom screening (SC) for especially advanced cancer patients (CPs). The aim of this multicenter German prospective quality assurance project KeSBa (Kennzahl Symptom- und Belastungserfassung) was to gain knowledge on SC procedures in Oncology Centers (OCs) for advanced cancer patients and a first impression on the consequences of SC. METHODS: The KeSBa project consisted of three phases: pilot, 3 months screening and feedback phase. Participating OCs decided to use either the Minimal Documentation System (MIDOS) or the Integrated Palliative care Outcome Scale (IPOS) and defined the cutoff values for positive screening results. RESULTS: Out of 172 certified German OCs, 40 (23%) participated in the KeSBa pilot phase, 29 (16.8%) in the 3 months screening phase using MIDOS (n = 18, 58.6%) or IPOS (n = 11, 41.3%) and in the feedback round. 25/29 performed paper-based screening (86.2%). 2.963 CPs were screened. Results were documented for 1255 (42.2%, SC +) positive and 874 (29.5%, SC-) negative screenings depending on the center´s schedules: 452 SC + CPs (28.4%) and 42 SC- CPs (2.6%) had contact to specialized palliative care or other supportive specialist teams afterwards, 458 SC + CPs (28.8%) and 605 SC- CPs (38.1%) remained in standard oncology care. In the feedback round missing resources (personal and IT) and improved communication were mentioned most often. CONCLUSION: Routine SC is feasible in advanced CPs treated in OCs but associated with considerable workload. In 42.2% of CPs SC was classified as positive, indicating the need of further diagnostics or professional judgment. SC requires staff and IT resources.

RESUMEN

OBJECTIVE: Early and open communication of palliative care (PC) and end-of-life (EoL)-related issues in advanced cancer care is not only recommended by guidelines, but also preferred by the majority of patients. However, oncologists tend to avoid timely addressing these issues. We investigated the role of oncologists' personal death anxiety in the rare occurrence of PC/EoL conversations. METHODS: We conducted a multicenter cross-sectional study assessing oncologists' strengths and difficulties in self-reported and externally rated PC/EoL communication skills as well as their association with death anxiety. Death anxiety was assessed via the Thanatophobia-Scale. PC/EoL communication skills were assessed via validated questionnaires and study-specific items plus an external rating of videotaped medical consultation with simulated patients. A general linear model was conducted to analyze associations. RESULTS: One hundred fifty-three oncologists participated (age: M(SD) = 32.9 years (6.9), 59.5% female). Both from the external and from their own perspective, oncologists had difficulties in addressing PC and the EoL. They avoided those aspects more than other topics in consultations with advanced cancer patients. Death anxiety was associated with more avoidant self-reported communication strategies, lower self-efficacy, less confidence in discussing the EoL and less confidence in discussing patients' goals and wishes, but was not associated with externally rated PC/EoL communication. CONCLUSIONS: Oncologists have experienced and externally observable difficulties in addressing PC and the EoL. Oncologists with higher death anxiety subjectively experience more difficulties. Group supervision and consultation offers might be means to empower oncologists, increase awareness of personal fears and enhance confidence and self-efficacy. This might facilitate earlier PC/EoL communication.

RESUMEN

OBJECTIVE: To translate the cancer-specific Body Image Scale (BIS) into German and assess its psychometric properties. METHODS: The BIS was translated in accordance with current guidelines. In a prospective, cross-sectional two center study (psychosocial counselling center for cancer patients Leipzig, oncological inpatient ward Berlin), we assessed composite reliability and factor structure using confirmatory factor analysis. Additional item response theory (IRT) modelling was performed. Convergent validity was assessed via correlation with the Body Appreciation Scale (BAS) as well as psychological symptom burden (PHQ-9, GAD-2 and Distress Thermometer). Discriminant validity was assessed via demographic and clinical group comparisons. RESULTS: 677 patients participated (response rate 78%). Composite reliability was 0.95 and the one-factor structure was confirmed (standardized root mean square residual = 0.051, average variance extracted ≥50%, no indications of local dependence). In IRT models, all items had a discriminating power above the established threshold of b = 0.5 and relatively high "difficulty" parameters (b = 0.89-2.06). The BIS was negatively correlated with the BAS (rho = -0.62, p < 0.001) and positively with psychological symptom burden (e.g. PHQ-9: rho = 0.49, p < 0.001). Patients who were younger, female, had undergone chemotherapy, radiotherapy or surgery and those who were distressed by fatigue, their appearance or sexual problems had significantly higher BIS scores. CONCLUSION: The German version of the BIS is a valid tool to assess BID in patients with cancer that is now available for clinical or research contexts.

RESUMEN

BACKGROUND: Fragmented and complex healthcare systems make it difficult to provide continuity of care for patients with advanced cancer near the end of life. Nurse-based cross-sectoral navigation support has the potential to increase patients' quality of life. The objective of this paper was to evaluate associations between navigation support and health care utilization, and the associated costs of care. METHODS: The evaluation is based on claims data from 37 statutory health insurance funds. Non-randomized recruitment of the intervention group (IG) took place between 2018 and 2019 in four German hospitals. The comparison group (CG) was defined ex post. It comprises nonparticipating clients of the involved health insurance funds matched on age, gender, and diagnosis in a 1:4 ratio to the IG. Healthcare resource utilization was compared using incident rate ratios (IRRs) based on negative binomial regression models. Linear mixed models were performed to compare differences in lengths of hospital stays and costs between groups. RESULTS: A total of 717 patients were included (IG: 149, CG: 568). IG patients showed shorter average lengths of hospital stays (IG: 11 days [95% CI: 10, 13] vs. CG: 15 days [95% CI: 14, 16], p < 0.001). In the IG, 21% fewer medications were prescribed and there were on average 15% fewer outpatient doctor contacts per month. Average billed costs in the IG were 23% lower than in the CG (IG: 6754 EUR [95% CI: 5702, 8000] vs. CG: 8816 EUR [95% CI: 8153, 9533], p < 0.001). CONCLUSIONS: The intervention was associated with decreased costs mainly as a result of a non-intended navigation effect. The social care nurses had navigated patients within the hospital early, needs-oriented and effectively but interpreted their function less cross-sectorally. Linkage of hospital-based navigators with the outpatient care sector needs further exploration.

RESUMEN

Importance: Approximately 50% of all patients with cancer have an indication for radiotherapy, and approximately 50% of radiotherapy is delivered with palliative intent, with the aim of alleviating symptoms. Symptoms are best assessed by patient-reported outcomes (PROs), yet their reliable interpretation requires adequate reporting in publications. Objective: To investigate the use and reporting of PROs in clinical trials of palliative radiotherapy. Evidence Review: This preregistered systematic review searched PubMed/Medline, EMBASE, and the Cochrane Center Register of Controlled Trials for clinical trials of palliative radiotherapy published from 1990 to 2020. Key eligibility criteria were palliative setting, palliative radiotherapy as treatment modality, and clinical trial design (per National Institutes of Health definition). Two authors independently assessed eligibility. Trial characteristics were extracted and standard of PRO reporting was assessed in adherence to the Consolidated Standards of Reporting Trials (CONSORT) PRO extension. The association of the year of publication with the use of PROs was assessed by logistic regression. Factors associated with higher CONSORT-PRO adherence were analyzed by multiple regression. This study is reported following the PRISMA guidelines. Findings: Among 7377 records screened, 225 published clinical trials representing 24 281 patients were eligible. Of these, 45 trials (20%) used a PRO as a primary end point and 71 trials (31%) used a PRO as a secondary end point. The most prevalent PRO measures were the Numeric Rating Scale/Visual Analogue Scale (38 trials), European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire C30 (32 trials), and trial-specific unvalidated measures (25 trials). A more recent year of publication was significantly associated with a higher chance of PROs as a secondary end point (odds ratio [OR], 1.04 [95% CI, 1.00-1.07]; P = .03) but not as primary end point. Adherence to CONSORT-PRO was poor or moderate for most items. Mean (SD) adherence to the extension adherence score was 46.2% (19.6%) for trials with PROs as primary end point and 31.8% (19.8%) for trials with PROs as a secondary end point. PROs as a primary end point (regression coefficient, 9.755 [95% CI, 2.270-17.240]; P = .01), brachytherapy as radiotherapy modality (regression coefficient, 16.795 [95% CI, 5.840-27.751]; P = .003), and larger sample size (regression coefficient, 0.028 [95% CI, 0.006-0.049]; P = .01) were significantly associated with better PRO reporting per extension adherence score. Conclusions and Relevance: In this systematic review of palliative radiotherapy trials, the use and reporting of PROs had room for improvement for future trials, preferably with PROs as a primary end point.

RESUMEN

PURPOSE: Up to 50% of radiotherapy courses are delivered in palliative intent for various indications. Despite the large number of treated patients, we know little about the choice of endpoints in trials of palliative radiotherapy. Our primary aim was, therefore, to analyze primary endpoints in trials of palliative radiotherapy. METHODS: We conducted a pre-registered (https://doi.org/10.17605/OSF.IO/GMCAF) meta-research analysis searching Pubmed/MEDLINE, EMBASE, CENTRAL, and "ClinicalTrials.gov" for clinical trials of palliative radiotherapy published 1990-2020. Endpoints were categorized in "patient-centered endpoints", including overall survival and patient-reported outcomes, and "tumor-centered endpoints" such as local control. The remainder were "other endpoints" including toxicity or observer-rated symptoms. We applied descriptive statistics to summarize data and logistic regression to assess if year of publication predicted the choice of primary endpoints. RESULTS: Of 7379 records screened, 292 were eligible. Trials were characterized by small sample sizes and use of external beam radiotherapy for metastases or thoracic primaries. Median patient age was 64 and median ECOG was 1. Only 64.4%(145/225) of published trials clearly stated their primary endpoint. Published trials employed a "patient-centered primary endpoint" in 45.5%(66/145) and a "tumor-centered primary endpoint" in 17.3%(25/145) of the cases. There was no statistically significant trend in time for the use of "patient-centered primary endpoints". Registered ongoing trials used a "patient-centered primary endpoint" in 32.8%(22/67) and a "tumor-centered primary endpoint" in 26.9%(18/67) of the cases. CONCLUSION: Although "patient-centered primary endpoints" appear relatively prevalent in published trials of palliative radiotherapy, their use is still suboptimal and appears to be lower in currently ongoing trials.

RESUMEN

PURPOSE: Given the psychosocial burdens patients in advanced stages of cancer face, innovative care concepts are needed. At the same time, such vulnerable patient groups are difficult to reach for participation in intervention studies and randomized patient inclusion may not be feasible. This article aims to identify systematic biases respectively selection effects occurring during the recruitment phase and to discuss their potential causes based on a non-randomized, multicenter intervention study with patients in advanced stages of cancer. METHODS: Patients diagnosed with at least one of 16 predefined cancers were recruited at four hospitals in three German cities. The effect of social care nurses' continuous involvement in acute oncology wards was measured by health-related quality of life (EORTC QLQ-C30), information and participation preferences, decisional conflicts, doctor-patient communication, health literacy and symptom perception. Absolute standardized mean difference was calculated as a standardized effect size to test baseline characteristics balance between the intervention and control groups. RESULTS: The study enrolled 362 patients, 150 in the intervention and 212 in the control group. Except for gender, both groups differed in relevant socio-demographic characteristics, e.g. regarding age and educational background. With respect to the distribution of diagnoses, the intervention group showed a higher symptom burden than the control group. Moreover, the control group reported better quality of life at baseline compared to the intervention group (52.6 points (SD 21.7); 47.8 points (SD 22.0), ASMD = 0.218, p = 0.044). CONCLUSION: Overall, the intervention group showed more social and health vulnerability than the control group. Among other factors, the wide range of diagnoses included and structural variation between the recruiting clinics increased the risk for bias. We recommend a close, continuous monitoring of relevant social and health-related characteristics during the recruitment phase as well as the use of appropriate statistical analysis strategies for adjustment, such as propensity score methods. TRIAL REGISTRATION: German Clinical Trials Register (DRKS-ID: DRKS00013640 ); registered on 29th December 2017.

RESUMEN

The diagnosis and treatment of cancer are associated with impairment at the physical and at psychological level. In addition, side effects are a potentially treatment-limiting factor that may necessitate dose reduction, delay, or even discontinuation of therapy, with negative consequences for outcome and mean survival. Numerous studies have shown that physical activity and sports and exercise therapy programs are not only practicable but also recommendable for oncologic patients during the acute phase and in the aftercare. Furthermore, nutrition plays an important role in all stages of tumor therapy. A timely integration of a nutrition therapy and physical activity in the form of physiotherapy and sports therapy serves to prevent and reduce treatment-associated side effects. Evidence-based recommendations on cancer prevention through nutrition therapy, physical activity, and sports and exercise therapy should be integrated into treatment plans for oncology patients as well as in health care services for the general population. Individual counselling by trained nutrition and exercise specialists may be advisable to receive concrete recommendations on the respective tumor entity or specific side effects. This mini review is based on a selective literature search in the PubMed database and Cochrane Central Register of Controlled Trials on the subjects of healthy diet and physical activity in primary prevention and follow-up about cancer.

RESUMEN

The National Cancer Plan emphasises the importance of medical communication and calls for its integration into medical education and training. In this context, the Milestone Communication Approach meets the communicative challenges in dealing with lung cancer patients. Interprofessional tandems, consisting of doctors and nurses, conduct structured conversations at defined moments with patients and their relatives. The concept aims at shared decision making, continuity in the care of lung cancer patients and the early integration of palliative care. During the symposium on the Heidelberg Milestone Communication in January 2020, recommendations on the care situation of lung cancer patients in advanced stages were developed. In addition, the further adaptability of HeiMeKOM to other settings and hospitals and to other diseases was discussed as well as the possibility of implementing such a concept in standard care. This article presents the experiences, best practice examples and recommendations discussed during the symposium in order to enable their extrapolation to other similarly oriented projects. The long-term goal is to transfer the milestone concept to other hospital, primarily certified lung cancer centers, and to ensure permanent funding. For further dissemination of the concept and, above all, to have it established in standard care, health policy awareness and support are required in addition to the integration of the concept in competence catalogues of continuing medical and nursing education.

RESUMEN

Objective: To test the psychometric properties, internal consistency, dimensional structure, and convergent validity of the German version of the Demoralization Scale-II (DS-II), and to examine the association between demoralization, sociodemographic, disease- and treatment-related variables in patients with cancer. Methods: We recruited adult patients with cancer at a Psychosocial Counseling Center and at oncological wards. Participants completed the 16-item DS-II, Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder Screener-2 (GAD-2), Distress Thermometer (DT), and Body Image Scale (BIS). We analyzed internal consistency of the DS-II using Cronbach's Alpha (α). We tested the dimensional structure of the DS-II with Confirmatory Factor Analyses (CFA). Convergent validity was expressed through correlation coefficients with established measures of psychological distress. The associations between demoralization, sociodemographic, disease- and treatment-related variables were examined with ANOVAs. Results: Out of 942 eligible patients, 620 participated. The average DS-II total score was M = 5.78, SD = 6.34, the Meaning and Purpose subscale M = 2.20, SD = 3.20, and the Distress and Coping Ability subscale M = 3.58, SD = 3.45. Internal consistency ranged from high to excellent with α = 0.93 for the DS-II total scale, α = 0.90 for the Meaning and Purpose subscale, and α = 0.87 for the Distress and Coping Ability subscale. The one-factor and the two-factor model yielded similar model fits, with CFI and TLI ranging between 0.910 and 0.933, SRMR < 0.05. The DS-II correlated significantly with depression (PHQ-9: r = 0.69), anxiety (GAD-2: r = 0.72), mental distress (DT: r = 0.36), and body image disturbance (BIS: r = 0.58). High levels of demoralization were reported by patients aged between 18 and 49 years (M = 7.77, SD = 6.26), patients who were divorced/separated (M = 7.64, SD = 7.29), lung cancer patients (M = 9.29, SD = 8.20), and those receiving no radiotherapy (M = 7.46, SD = 6.60). Conclusion: The DS-II has very good psychometric properties and can be recommended as a reliable tool for assessing demoralization in patients with cancer. The results support the implementation of a screening for demoralization in specific risk groups due to significantly increased demoralization scores.

RESUMEN

To date, extensive efforts to harness immunotherapeutic strategies for the treatment of pancreatic ductal adenocarcinoma (PDAC) have yielded disappointing results in clinical trials. These strategies mainly focused on cancer vaccines and immune checkpoint inhibitors alone or in combination with chemotherapeutic or targeted agents. However, the growing preclinical and clinical data sets from these efforts have established valuable insights into the immunological characteristics of PDAC biology. Most notable are the immunosuppressive role of the tumour microenvironment (TME) and PDAC's characteristically poor immunogenicity resulting from tumour intrinsic features. Moreover, PDAC tumour heterogeneity has been increasingly well characterized and may additionally limit a "one-fits-all" immunotherapeutic strategy. In this review, we first outline mechanisms of immunosuppression and immune evasion in PDAC. Secondly, we summarize recently published data on preclinical and clinical efforts to establish immunotherapeutic strategies for the treatment of PDAC including diverse combinatorial treatment approaches aiming at overcoming this resistance towards immunotherapeutic strategies. Particularly, these combinatorial treatment approaches seek to concomitantly increase PDAC antigenicity, boost PDAC directed T-cell responses, and impair the immunosuppressive character of the TME in order to allow immunotherapeutic agents to unleash their full potential. Eventually, the thorough understanding of the currently available data on immunotherapeutic treatment strategies of PDAC will enable researchers and clinicians to develop improved treatment regimens and to design innovative clinical trials to overcome the pronounced immunosuppression of PDAC.

RESUMEN

PURPOSE: Although subjective knowledge about the prognosis of an advanced disease is extremely important for coping and treatment planning, the concept of prognostic awareness (PA) remains inconsistently defined. The aims of the scoping review were to synthesize a definition of PA from the most recent literature, describe preconditions, correlates and consequences, and suggest a conceptual model. METHODS: By using scoping review methodology, we searched the Web of Science and PubMed databases, and included publications, reviews, meta-analyses or guidelines on all physical diagnoses, as well as publications offering a conceptual or an operational definition of PA. The data were analyzed by means of content analysis techniques. RESULTS: Of the 24 included publications, 21 referred exclusively to cancer, one to patients with hip fractures and two to palliative care in general. The deduced definition of PA comprised the following facets: adequate estimation of chances for recovery, knowledge of limited time to live, adequate estimation of life expectancy, knowledge of therapy goals, and knowledge of the course of the disease. Further content analysis results were mapped graphically and in a detailed table. CONCLUSION: There appears to be a lack of theoretical embedding of PA that in turn influences the methods used for empirical investigation. Drawing on a clear conceptual definition, longitudinal or experimental studies would be desirable.

RESUMEN

Myelodysplastic syndrome (MDS) with isolated deletion of chromosome 5q (MDS del5q) is a distinct subtype of MDS with quite favorable prognosis and excellent response to treatment with lenalidomide. Still, a relevant percentage of patients do not respond to lenalidomide and even experience progression to acute myeloid leukemia (AML). In this study, we aimed to investigate whether global DNA methylation patterns could predict response to lenalidomide. Genome-wide DNA methylation analysis using Illumina 450k methylation arrays was performed on n=51 patients with MDS del5q who were uniformly treated with lenalidomide in a prospective multicenter trial of the German MDS study group. To study potential direct effects of lenalidomide on DNA methylation, 17 paired samples pre- and post-treatment were analyzed. Our results revealed no relevant effect of lenalidomide on methylation status. Furthermore, methylation patterns prior to therapy could not predict lenalidomide response. However, methylation clustering identified a group of patients with a trend towards inferior overall survival. These patients showed hypermethylation of several interesting target genes, including genes of relevant signaling pathways, potentially indicating the evaluation of novel therapeutic targets.

RESUMEN

OBJECTIVE: Prognostic awareness is essential for making treatment decisions in malignant diseases. Being confronted with a poor prognosis, however, can affect patients' mental health. Therefore, it is important to study coping in the context of malignant diseases. Acceptance is an adaptive coping strategy associated with less psychological distress. This study sought to explore the facilitators and barriers for prognostic acceptance in a sample in which both hope and uncertainty regarding prognosis are pronounced: multiple myeloma patients. METHODS: In a German university hospital, 20 multiple myeloma patients participated in semistructured interviews. Following thematic content analysis by Kuckartz, the interview transcripts were coded for facilitators and barriers for prognostic acceptance. Additionally, patients completed questionnaires on prognostic awareness and sociodemographic characteristics. RESULTS: Patients described the following facilitators for prognostic acceptance: social support, positive thinking, focusing on the Here and Now, proactive confrontation, having little to no symptoms, and being there for others. The indicated barriers were distressing physical symptoms and restricted functioning, social distress, and additional distress from other areas of life. CONCLUSIONS: Patients reported a variety of factors-related to the social realm, symptom burden, and specific attitudes-that help or hinder them in accepting their prognosis. Oncologists and psycho-oncologists may support prognostic acceptance by encouraging patients to both actively deal with realistic information as well as enjoy pleasant and meaningful moments in the present during which the disease and its prognosis recedes into the background.

RESUMEN

PURPOSE: Despite promising achievements in precision cancer medicine (PCM), participating patients are still faced with manifold uncertainties, especially regarding a potential treatment benefit of molecular diagnostics (MD). Hence, MD poses considerable challenges for patient information and communication. To meet these challenges, healthcare professionals need to gain deeper insight into patients' subjective experiences. Therefore, this qualitative study examined information aspects of MD programs in cancer patients. METHODS: In two German Comprehensive Cancer Centers, 30 cancer patients undergoing MD participated in semi-structured interviews on information transfer and information needs regarding MD. Additionally, patients provided sociodemographic and medical data and indicated their subjective level of information (visual analogue scale, VAS, 0-10). RESULTS: On average patients had high levels of information (mean = 7, median = 8); nevertheless 20% (n = 6) showed an information level below 5 points. Qualitative analysis revealed that patients show limited understanding of the complex background of MD and have uncertainties regarding their personal benefit. Further, patients described unmet information needs. Existential threat in awaiting the results was experienced as burdensome. To withstand the strains of their situation, patients emphasized the importance of trusting their physician. CONCLUSION: The challenges in PCM consist in providing unambiguous information, especially concerning treatment benefit, and providing guidance and support. Therefore, psycho-oncology needs to develop guidelines for adequate patient communication in order to help healthcare providers and cancer patients to handle these challenges in the developing field of PCM.

RESUMEN

BACKGROUND: Early integration of palliative care concurrently to standard cancer care is associated with several benefits for patients and their caregivers. However, communication barriers on part of the caring physicians often impede a timely referral to palliative care. This study describes the protocol of the evaluation of a communication skills training aiming to strengthen the ability of physicians to address palliative care related topics adequately and early during disease trajectory. METHODS: We will implement a communication skills training and evaluate it within a prospective, multi-centered, two-armed randomized controlled trial (RCT), which will be conducted at four sites in Germany. Eligible subjects are all physicians treating patients with advanced cancer in their daily routine. An intervention group (IG) receiving a group training will be compared to a wait-list control group (CG) receiving the training after completion of data collection. At pre- and post-measurement points, participants will conduct videotaped conversations with standardized simulated patients (SP). Primary outcome will be the external rating of communication skills and consulting competencies addressing palliative care related topics. Secondary outcomes on core concepts of palliative care, basic knowledge, attitudes, confidence and self-efficacy will be assessed by standardized questionnaires and self-developed items. A further external assessment of the quality of physician-patient-interaction will be conducted by the SP. Longitudinal quantitative data will be analyzed using covariate-adjusted linear mixed-models. DISCUSSION: If the communication skills training proves to be effective, it will provide a feasible intervention to promote an earlier communication of palliative care related topics in the care of advanced cancer patients. This would help to further establish early integration of palliative care as it is recommended by national and international guidelines.

RESUMEN

Cyclin A1 is a promising antigen for T cell therapy being selectively expressed in high-grade ovarian cancer (OC) and acute myeloid leukemia (AML) stem cells. For adoptive T cell therapy, a single epitope has to be selected, with high affinity to MHC class I and adequate processing and presentation by malignant cells to trigger full activation of specific T cells. In silico prediction with three algorithms indicated 13 peptides of Cyclin A1 9 to 11 amino acids of length to have high affinity to HLA-A*02:01. Ten of them proved to be affine in an HLA stabilization assay using TAP-deficient T2 cells. Their immunogenicity was assessed by repetitive stimulation of CD8+ T cells from two healthy donors with single-peptide-pulsed dendritic cells or monocytes. Intracellular cytokine staining quantified the enrichment of peptide-specific functional T cells. Seven peptides were immunogenic, three of them against both donors. Specific cell lines were cloned and used in killing assays to demonstrate recognition of endogenous Cyclin A1 in the HLA-A*02:01-positive AML cell line THP-1. Immunopeptidome analysis based on direct isolation of HLA-presented peptides by mass spectrometry of primary AML and OC samples identified four naturally presented epitopes of Cyclin A1. The immunopeptidome of HeLa cells transfected with Cyclin A1 and HLA-A*02:01 revealed six Cyclin A1-derived HLA ligands. Epitope p410-420 showed high affinity to HLA-A*02:01 and immunogenicity in both donors. It proved to be naturally presented on primary AML blast and provoked spontaneous functional response of T cells from treatment naïve OC and, therefore, warrants further development for clinical application.

RESUMEN

OBJECTIVE: Precision cancer medicine (PCM) aims at identifying tumor-driving molecular characteristics to improve therapy. Despite early successes for some cancers, the approach faces manifold challenges. Patients undergoing extensive molecular diagnostics (MD) may hope for personal benefit, although chances are small. In order to offer suitable support to this group, health-care professionals need to gain insight into patients' experience. Thus, this study sought to explore the expectations of cancer patients undergoing MD of their tumor. METHODS: In two German Comprehensive Cancer Centers, 30 patients with advanced-stage cancer who had exhausted conventional treatment and had consented to extensive, research-oriented MD (whole-genome sequencing n = 24, panel sequencing n = 6) participated in semi-structured interviews. Following thematic content analysis by Kuckartz, the interview transcripts were coded for expectations of MD participation and topics closely related. Moreover, patients completed questionnaires on their sociodemographic characteristics, medical history, and psychosocial distress. RESULTS: Patients reported to be expecting (a) an improvement of their treatment, (b) a contribution to research, and/or (c) additional insight to their own cancer. Further, they described to feel individually appreciated and to have a reason to maintain hope for cure or recovery by participating in MD. CONCLUSIONS: Molecular diagnostics participation led patients to feel treated in a more "personalized" way, allowing them a greater sense of control in their situation of severe illness. Oncologists and psycho-oncologists need to ensure comprehensive information and empathetic support for patients undergoing extensive MD to balance their expectations and actual chances of clinical benefit.
