The OUTREACH study: oncologists of German university hospitals in rotation on a palliative care unit-evaluation of attitude and competence in palliative care and hospice.

PURPOSE: The effect of the duration of an educational rotation presented at a palliative care unit on the palliative care knowledge gain and the increase of palliative care self-efficacy expectations are unclear. METHODS: This national prospective multicenter pre-post survey conducted at twelve German University Comprehensive Cancer Centers prospectively enrolled physicians who were assigned to training rotations in specialized palliative care units for three, six, or twelve months. Palliative care knowledge [in %] and palliative care self-efficacy expectations [max. 57 points] were evaluated before and after the rotation with a validated questionnaire. RESULTS: From March 2018 to October 2020, questionnaires of 43 physicians were analyzed. Physicians participated in a 3- (n = 3), 6- (n = 21), or 12-month (n = 19) palliative care rotation after a median of 8 (0-19) professional years. The training background of rotating physicians covered a diverse spectrum of specialties; most frequently represented were medical oncology (n = 15), and anesthesiology (n = 11). After the rotation, median palliative care knowledge increased from 81.1% to 86.5% (p < .001), and median palliative care self-efficacy expectations scores increased from 38 to 50 points (p < .001). The effect of the 12-month rotation was not significantly greater than that of the 6-month rotation. CONCLUSION: An educational rotation presented in a specialized palliative care unit for at least six months significantly improves palliative care knowledge and palliative care self-efficacy expectations of physicians from various medical backgrounds.

Symptom burden, psychosocial distress and palliative care needs in heart failure - A cross-sectional explorative pilot study.

BACKGROUND: Beyond guideline-directed treatments aimed at improving cardiac function and prognosis in heart failure (HF), patient-reported outcomes have gained attention. PURPOSE: Using a cross-sectional approach, we assessed symptom burden, psychosocial distress, and potential palliative care (PC) needs in patients with advanced stages of HF. METHODS: At a large tertiary care center, we enrolled HF patients in an exploratory pilot study. Symptom burden and psychosocial distress were assessed using the MIDOS (Minimal Documentation System for Patients in PC) questionnaire and the Distress Thermometer (DT), respectively. The 4-item Patient Health Questionnaire (PHQ-4) was used to screen for anxiety and depression. To assess PC needs, physicians used the "Palliative Care Screening Tool for HF Patients". RESULTS: We included 259 patients, of whom 137 (53%) were enrolled at the Heart Failure Unit (HFU), and 122 (47%) at the outpatient clinic (OC). Mean age was 63 years, 72% were male. New York Heart Association class III or IV symptoms were present in 56%. With a mean 5-year survival 64% (HFU) vs. 69% (OC) calculated by the Seattle Heart Failure Model, estimated prognosis was comparatively good. Symptom burden (MIDOS score 8.0 vs. 5.4, max. 30 points, p < 0.001) and level of distress (DT score 6.0 vs. 4.8, max. 10 points, p < 0.001) were higher in hospitalised patients. Clinically relevant distress was detected in the majority of patients (HFU 76% vs. OC 57%, p = 0.001), and more than one third exhibited at least mild symptoms of depression or anxiety. Screening for PC needs revealed 82% of in- and 52% of outpatients fulfil criteria for specialized palliative support. CONCLUSION: Despite a good prognosis, we found multiple undetected and unaddressed needs in an advanced HF cohort. This study's tools and screening results may help to early explore these needs, to further improve integrated HF care.

Effects of a communication training for oncologists on early addressing palliative and end-of-life care in advanced cancer care (PALLI-COM): a randomized, controlled trial.

INTRODUCTION: In advanced cancer care, early communication about palliative care (PC) and end-of-life (EoL)-related issues is recommended, but is often impeded by physicians' communication insecurities. We investigated the effect of a newly developed compact communication skills training 'PALLI-COM' on oncologists' competencies to early address PC/EoL-related issues. MATERIALS AND METHODS: We conducted a randomized, controlled trial (RCT) with an intervention group (IG; 2 × 90 min training) and a wait list control group (CG) at five sites. At two assessment points, participating oncologists led videotaped medical consultations with simulated patients (SPs) via a privacy compliant video conference platform. SPs were represented by trained actors. The taped conversations were rated for primary outcome (communication skills assessed by adapted COM-ON-checklist and COM-ON-coaching rating scales) by raters blinded for study group. Secondary outcomes included oncologists' self-reported communication skills (Self-Efficacy in Palliative Care Scale, Thanatophobia-Scale, Communication about End of Life Survey, study-specific items) as well as external rating of the SPs. Univariate analyses of covariance with baseline adjustment were used to analyze intervention effects. RESULTS: A total of 141 oncologists [age: mean (standard deviation) = 32.7 (6.3) years, 60% female (nIG = 73, nCG = 68)] participated. Following intervention, the IG showed significantly more improvement in four out of five assessed communication skills: 'reacting to emotions and showing empathy', 'pointing out opportunities and giving hope', 'addressing the EoL' and 'explaining the concept of PC'. IG participants also improved more than CG participants in almost all secondary outcomes assessed by participants and SPs: oncologists' self-efficacy, attitudes towards caring for terminally ill patients, communication strategies and confidence in dealing with PC/EoL-related issues as well as communication quality from the SPs' perspective. CONCLUSION: Findings indicate that the compact communication skills training PALLI-COM increases oncologists' competencies in early addressing PC/EoL-related issues from different perspectives. Implementation in routine oncology residency might improve advanced cancer care by strengthening these communication skills.

Preventing adverse events of chemotherapy for gastrointestinal cancer by educating patients about the nocebo effect: a randomized-controlled trial.

BACKGROUND: Adverse events of chemotherapy may be caused by pharmacodynamics or psychological factors such as negative expectations, which constitute nocebo effects. In a randomized controlled trial, we examined whether educating patients about the nocebo effect is efficacious in reducing the intensity of self-reported adverse events. METHODS: In this proof-of-concept study, N = 100 outpatients (mean age: 60.2 years, 65% male, 54% UICC tumour stage IV) starting first-line, de novo chemotherapy for gastrointestinal cancers were randomized 1:1 to a nocebo education (n = 49) or an attention control group (n = 51). Our primary outcome was patient-rated intensity of four chemotherapy-specific and three non-specific adverse events (rated on 11-point Likert scales) at 10-days and 12-weeks after the first course of chemotherapy. Secondary outcomes included perceived control of adverse events and tendency to misattribute symptoms. RESULTS: General linear models indicated that intensity of adverse events differed at 12-weeks after the first course of chemotherapy (mean difference: 4.04, 95% CI [0.72, 7.36], p = .02, d = 0.48), with lower levels in the nocebo education group. This was attributable to less non-specific adverse events (mean difference: 0.39, 95% CI [0.04, 0.73], p = .03, d = 0.44) and a trend towards less specific adverse events in the nocebo education group (mean difference: 0.36, 95% CI [- 0.02, 0.74], p = .07, d = 0.37). We found no difference in adverse events at 10-days follow-up, perceived control of adverse events, or tendency to misattribute non-specific symptoms to the chemotherapy. CONCLUSIONS: This study provides first proof-of-concept evidence for the efficacy of a brief information session in preventing adverse events of chemotherapy. However, results regarding patient-reported outcomes cannot rule out response biases. Informing patients about the nocebo effect may be an innovative and clinically feasible intervention for reducing the burden of adverse events. TRIAL REGISTRATION: Retrospectively registered on March 27, 2018 to the German Clinical Trial Register (ID: DRKS00009501).

National strategy for palliative care of severely ill and dying people and their relatives in pandemics (PallPan) in Germany - study protocol of a mixed-methods project.

BACKGROUND: In the SARS-CoV-2 pandemic, general and specialist Palliative Care (PC) plays an essential role in health care, contributing to symptom control, psycho-social support, and providing support in complex decision making. Numbers of COVID-19 related deaths have recently increased demanding more palliative care input. Also, the pandemic impacts on palliative care for non-COVID-19 patients. Strategies on the care for seriously ill and dying people in pandemic times are lacking. Therefore, the program 'Palliative care in Pandemics' (PallPan) aims to develop and consent a national pandemic plan for the care of seriously ill and dying adults and their informal carers in pandemics including (a) guidance for generalist and specialist palliative care of patients with and without SARS-CoV-2 infections on the micro, meso and macro level, (b) collection and development of information material for an online platform, and (c) identification of variables and research questions on palliative care in pandemics for the national pandemic cohort network (NAPKON). METHODS: Mixed-methods project including ten work packages conducting (online) surveys and qualitative interviews to explore and describe i) experiences and burden of patients (with/without SARS-CoV-2 infection) and their relatives, ii) experiences, challenges and potential solutions of health care professionals, stakeholders and decision makers during the SARS-CoV-2 pandemic. The work package results inform the development of a consensus-based guidance. In addition, best practice examples and relevant literature will be collected and variables for data collection identified. DISCUSSION: For a future "pandemic preparedness" national and international recommendations and concepts for the care of severely ill and dying people are necessary considering both generalist and specialist palliative care in the home care and inpatient setting.

[Virtual palliative care : Pilot study of an electronic tool to test cognitive, psychomotor and affective palliative medical and pain therapeutic learning contents during medical training]. / Virtuelle Palliativversorgung : Pilotierung eines elektronischen Tools zur Prüfung kognitiver, psychomotorischer und affektiver palliativmedizinischer und schmerztherapeutischer Lerninhalte während der ärztlichen Ausbildung.

BACKGROUND: This article describes a first use of an electronic case-based assessment tool in undergraduate palliative care education. It describes the development of the tool presenting strengths and shortcomings in order to contribute to an innovative design of assessment tools in medical education. DESIGN AND METHOD: An electronic (virtual) case-based assessment tool (the virtual palliative patient, vPp) was developed. Palliative care levels of knowledge, skills and attitude of students were tested at a computer workplace as a voluntary and non-performance-relevant pilot project at four faculties. RESULTS: On average the students achieved 80% of the points using the vPp tool, which is below the average score of 91% achieved in the regular examination. In particular, the free text task on reflection of dealing with the patient's death wish caused uncertainty, while multiple choice questions and an interactive conversation sequence were perceived as relatively easy. Technical problems were also identified in the evaluation but overall the concept was evaluated positively and establishment as a regular examination or e­learning tool was desired. CONCLUSION: The implementation of an innovative assessment tool in medical education is technically challenging. A coordination with contents of the individual faculties is necessary in order that students do not have a feeling of a lack of preparation. The development of the vPp describes an innovative assessment format. In the long term, all interested faculties could receive a form of toolbox containing the technical framework of the assessment tool, which can then be fed with new contents.

[Positron emission tomography in germ cell tumors in men : Possibilities and limitations]. / Positronenemissionstomographie bei Keimzelltumoren des Mannes : Einsatzmöglichkeiten und Grenzen.

BACKGROUND: Conventional radiographic imaging may fail to safely distinguish clinical stage I from stage IIA germ cell cancer, to localize isolated tumor marker relapses, and to equivocally identify the viability of postchemotherapy residual masses. OBJECTIVES: To provide an overview of the diagnostic value and limitations of functional imaging by positron emission tomography with 2­deoxy-2-[fluorine-18]fluoro-D-glucose with computed tomography (18F-FDG-PET-CT) in male germ cell cancer. MATERIALS AND METHODS: A narrative review based on a literature search of PubMed/MEDLINE for original articles published from 1990-2018 and conference proceedings of ASCO (American Society of Clinical Oncology) and EAU (European Association of Urology) annual meetings 2014-2017 is presented. RESULTS: 18F-FDG-PET-CT does not improve diagnostic accuracy compared to conventional CT imaging clinical stage (CS) I disease. Particularly PET-negativity of postchemotherapy residual masses of seminomas >3 cm in size guide decision-making against further additional treatment. Even PET-positive residues must not result in relapse. For nonseminoma, the value of PET imaging is reduced by potential mature teratoma components, which are commonly PET negative. CONCLUSIONS: Current guidelines recommend 18F-FDG-PET-CT 6-8 weeks postchemotherapy for viability assessment of seminoma residues >3 cm in size. Exceptional circumstances, in which 18F-FDG-PET-CT may be helpful, include: (1) detection of active disease in CS IS, (2) viability assessment of residual masses >1 cm where complete secondary resection is impossible, (3) staging at marker relapse with unconspicuous conventional CT scan, (4) early response assessment during chemotherapy.

[Palliative care]. / Palliativmedizin.

Improvement in the quality of life of patients with life-threatening illnesses or incurable progressive diseases, including patients with cancer and also several internal medical diseases, represents the major aim of palliative care. Basic principles are to also address the needs of the family caregiver and a comprehensive understanding of physical symptoms and psychosocial as well as spiritual aspects. Treatment planning for physical symptoms, e.g., pain, dyspnea and nausea, in patients in need of palliative care has to include the subjective symptom distress of the patient, factors that can be treated causally and the treatment limitations resulting from the underlying life-threatening or incurable disease. During terminal care all treatment measures should only focus on relief of symptom burden and fulfilling the patient's will.

The daily dynamics of loss orientation and life engagement in advanced cancer: A pilot study to characterise patterns of adaptation at the end of life.

Individual adaptation at the end of life may be characterised by how patients fluctuate in their orientation towards losses and death or engagement in meaningful activities in daily life. To describe these intraindividual patterns of change, we conducted a daily diary study over 7 days with 17 advanced cancer patients from in- and outpatient oncology and psycho-oncology clinics. Patients reported on the daily frequency of behaviours associated with loss orientation and life engagement using a standardised questionnaire. We characterised each patient's pattern of change with three parameters: the mean level (5-point-scale from 0 = never to 4 = always), mean fluctuation between successive days (MSSD) and the association between changes in loss and life orientation over time. We further explored the relationship between these patterns and free-text diaries. The daily assessment protocol was acceptable and feasible (46% participation rate, 97% diary completion rate). Individuals differed in mean levels of loss orientation (range: M = 0.1 to 2.7) and life engagement (M = 0.9 to 3.9), the degree of fluctuation (MSSD = 0.1 to 1.5 and MSSD = 0.3 to 0.9), and the correlations between these changes over time (r = -.83 to +.46), revealing distinctive intraindividual patterns. Further study of individual profiles in loss and life orientation can promote personalised balancing between facing "reality" and sustaining "hope" in end-of-life conversations.

Impact of primary metastatic bone disease in germ cell tumors: results of an International Global Germ Cell Tumor Collaborative Group G3 Registry Study.

Background: Bone metastases (BM) are rare in germ cell tumor (GCT) patients. Systematic data on risk factors, treatment and outcome are largely lacking. Patients and methods: A database created by an international consortium including 123 GCT patients with BM at primary diagnosis was retrospectively analysed. Survival estimates were calculated by the method of Kaplan-Meier and compared by log-rank testing. Cox regression analysis was applied for risk factor analyses. Results: In our cohort of patients, BM at primary diagnosis more often affected multiple sites (61%) and BM as the only metastatic site were scarce (9%). Histology was non-seminoma in 77% and seminoma in 23% of patients. After a median follow-up of 18 months (range, 0-228), estimated median PFS and OS were 21 (range, 0-225) and 98 months (95%CI, 36-160), respective 2-year PFS and OS rates were 34% and 45%. Negative prognosticators in univariate analysis were a mediastinal primary (PFS; HR 1.92; 95%CI, 1.05-3.50; OS; HR 2.16; 95%CI, 1.14-4.09) and the presence of liver and/or brain metastases (PFS; HR 1.89; 95%CI, 1.13-3.17; OS; HR 1.91; 95%CI, 0.024) Seminomatous histology was the strongest predictor for favorable PFS (multivariate Cox regression; HR, 0.32; P=0.011) with respective 2-year PFS and OS rates of 68% and 75% compared with 24% and 36% for non-seminoma patients. Conclusions: Outcome of GCT patients with primary metastatic bone disease is particularly poor in non-seminoma patients, even worse than the expected outcomes of the general IGCCCG 'poor prognosis' group. This series does not indicate that mutlimodal treatment improves the prognosis over stage-adapted chemotherapy alone, however, the statistical power of these results is limited due to low patient numbers in each specific subgroup.

Detrimental social interactions predict loss of dignity among patients with cancer.

PURPOSE: This prospective study aimed to determine the extent to which cancer patients experience loss of dignity during primary cancer care (baseline) and at 3-month follow-up and the contribution of positive social support and detrimental social interactions on loss of dignity at follow-up. METHODS: At baseline, we enrolled N = 270 cancer patients (advanced cancer 57 %) undergoing oncological treatment. At follow-up, n = 178 patients (72 %) participated. Patients completed the following questionnaires: sense of dignity item (SDI), physical problem list of the NCCN Distress Thermometer, Illness-Specific Social Support Scale (SSUK), Patient Health Questionnaire (PHQ-9), and Generalized Anxiety Disorder Questionnaire (GAD-7). We conducted ordinal regression analyses controlling for age, gender, tumor stage, number of physical symptoms, depression, and anxiety. RESULTS: At baseline, 18 % of the patients experienced moderate to extreme loss of dignity (follow-up 23 %, p = 0.27). Detrimental interactions significantly predicted loss of dignity (OR = 1.42, 95 % CI 1.06-1.90) in a model including positive support (OR = 1.10, 95 % CI 0.82-1.49), depression (OR = 1.55, 95 % CI 0.96-2.51), and anxiety (OR = 1.20, 95 % CI 0.83-1.74). Items in relation to detrimental interactions with significant others such as "made you feel like you couldn't take care of yourself" (r = 0.29, p < 0.001) and "felt uncomfortable in illness conversations" (r = 0.24, p = 0.002) showed the highest associations with perceived loss of dignity. CONCLUSION: Loss of dignity was a frequent problem in our mixed cancer patient sample. Detrimental interactions that weaken the sense of dignity may result from discrepancies with patients' needs for autonomy and security. Tailoring social support to attachment-related patient needs may help to conserve patients' sense of dignity.

[State of integration of palliative care at Comprehensive Cancer Centers funded by German Cancer Aid]. / Integration der Palliativmedizin in die von der Deutschen Krebshilfe e. V. geförderten onkologischen Spitzenzentren.

BACKGROUND: Similarities and differences of integration of palliative care in clinical care, research and education structures at German Comprehensive Cancer Centers (CCC) are not known in detail. OBJECTIVE: Provide an overview of availability and the way of integration of specialized palliative care at CCCs funded by the German Cancer Aid (Deutsche Krebshilfe, DKH). METHOD: We conducted structured interviews from May to August 2014 with heads of palliative care departments (personally or by telephone). The interviews included a quantitative and a qualitative part. Other stakeholders of CCCs were asked the questions of the qualitative part. We evaluated the qualitative data using the content analysis by Mayring and MAXQDA 11.0. SPSS 21.0 was used for quantitative analysis. RESULTS: 26 interviews were realized in 13 CCCs with 14 sites, which received funding, by DKH till August 2014 (one CCC had two university hospitals). Of these, 12 sites had a palliative care unit (86%), 11 sites had palliative care consulting services available (79%). Participation of palliative care specialists in tumor boards is not provided in 3 institutions (21%) and is often not feasible on regular basis in the other institutions, due to staffing shortage. In 7 sites (50%) defined criteria to integrate palliative care into CCCs were available. In the last 5 years specialized palliative care of 4 sites received an invitation for a research project by another department within the CCC (29%). 10 sites (71%) had started own palliative care research projects. Chairs in palliative care were available in 4 CCCs (29%). CONCLUSION: The extent and depth of palliative care integration in the 14 CCC sites is heterogeneous.

Prognostic impact of progression to induction chemotherapy and prior paclitaxel therapy in patients with germ cell tumors receiving salvage high-dose chemotherapy in the last 10 years: a study of the European Society for Blood and Marrow Transplantation Solid Tumors Working Party.

Little is known about the prognostic impact of prior paclitaxel therapy and response to induction chemotherapy defined as the regimen preceding high-dose chemotherapy (HDCT) for the salvage therapy of advanced germ cell tumors. Twenty European Society for Blood and Marrow Transplantation centers contributed data on patients treated between 2002 and 2012. Paclitaxel used in either prior lines of therapy or in induction-mobilization regimens was considered. Multivariable Cox analyses of prespecified factors were undertaken on PFS and overall survival (OS). As of October 2013, data for 324 patients had been contributed to this study. One hundred and ninety-two patients (59.3%) had received paclitaxel. Sixty-one patients (19%) had a progression to induction chemotherapy, 234 (72%) a response (29 (9%) missing or granulocyte colony-stimulating factor without chemotherapy). Both progression to induction chemotherapy and prior paclitaxel were significantly associated with shorter OS univariably (P<0.001 and P=0.032). On multivariable analysis from the model with fully available data (N=216) progression to induction was significantly prognostic for PFS and OS (P=0.003), but prior paclitaxel was not (P=0.674 and P=0.739). These results were confirmed after multiple imputation of missing data. Progression to induction chemotherapy could be demonstrated as an independent prognostic factor, in contrast to prior paclitaxel.

Anxiety and depression in long-term testicular germ cell tumor survivors.

OBJECTIVE: Despite a good prognosis, the typically young age at diagnosis and physical sequelae may cause psychological distress in germ cell tumor survivors. We aimed to determine the frequency of anxiety and depression and analyze the impact of demographic and disease-related factors. METHOD: We enrolled N=164 testicular germ cell tumor survivors receiving routine follow-up care at the University Cancer Center Hamburg and a specialized private practice (mean, 11.6 years after diagnosis). Patients completed the Generalized Anxiety Disorder Screener-7, the Patient Health Questionnaire-9 and the Memorial Symptom Assessment Scale-Short Form. RESULTS: We found clinically significant anxiety present in 6.1% and depression present in 7.9% of survivors. A higher number of physical symptoms and having children were significantly associated with higher levels of both anxiety and depression in multivariate regression analyses controlling for age at diagnosis, cohabitation, socioeconomic status, time since diagnosis, metastatic disease and relapse. Younger age at diagnosis and shorter time since diagnosis were significantly associated with higher anxiety. CONCLUSION: Although rates of clinically relevant anxiety and depression were comparably low, attention toward persisting physical symptoms and psychosocial needs related to a young age at diagnosis and having children will contribute to address potential long-term psychological distress in germ cell tumor survivors.

[Communication Bad News by Physicians: The German Version of the MPP (Measure of Patients' Preferences) Questionnaire to the Communicative Preferences of Cancer Patients]. / Die Mitteilung schlechter Nachrichten durch den Arzt: Die deutsche Version des MPP- (Measure of Patients' Preferences) Fragebogens zu den kommunikativen Präferenzen von Krebspatienten.

OBJECTIVES: Breaking bad news is as one of the most distressing tasks that doctors face with high demands on their communication and psychosocial skills. Patient preferences for communicating bad news influence the course of such consultations. The purpose of this study was to evaluate the psychometric characteristics of the German version of the Measure of Patients' Preferences (MPP), a questionnaire that has been validated in several international studies. METHOD: Statistical analyses were performed in a sample of N=270 cancer patients during early treatment phase (mixed cancer entities, mean age 56.9 years, 46.7% female). In this prospective study with 2 assessment times, the factorial structure of the MPP-D was examined using principal components analysis with varimax rotation. RESULTS: Factor analysis resulted in a 9-factor solution, the 3 factor structure of the original version was not replicated. Cronbachs α was>0.80 for 7 of the MPP-D subscales indicating good to excellent reliability. CONCLUSION: Further psychometric testing and optimisation of the measure is recommended.

Maintaining success, reducing treatment burden, focusing on survivorship: highlights from the third European consensus conference on diagnosis and treatment of germ-cell cancer.

In November 2011, the Third European Consensus Conference on Diagnosis and Treatment of Germ-Cell Cancer (GCC) was held in Berlin, Germany. This third conference followed similar meetings in 2003 (Essen, Germany) and 2006 (Amsterdam, The Netherlands) [Schmoll H-J, Souchon R, Krege S et al. European consensus on diagnosis and treatment of germ-cell cancer: a report of the European Germ-Cell Cancer Consensus Group (EGCCCG).

European consensus conference on diagnosis and treatment of germ-cell cancer: a report of the second meeting of the European Germ-Cell Cancer Consensus group (EGCCCG): part II. Eur Urol 2008; 53: 497-513]. A panel of 56 of 60 invited GCC experts from all across Europe discussed all aspects on diagnosis and treatment of GCC, with a particular focus on acute and late toxic effects as well as on survivorship issues. The panel consisted of oncologists, urologic surgeons, radiooncologists, pathologists and basic scientists, who are all actively involved in care of GCC patients. Panelists were chosen based on the publication activity in recent years. Before the meeting, panelists were asked to review the literature published since 2006 in 20 major areas concerning all aspects of diagnosis, treatment and follow-up of GCC patients, and to prepare an updated version of the previous recommendations to be discussed at the conference. In addition, ∼50 E-vote questions were drafted and presented at the conference to address the most controversial areas for a poll of expert opinions. Here, we present the main recommendations and controversies of this meeting. The votes of the panelists are added as online supplements.

2-¹8fluoro-deoxy-D-glucose positron emission tomography (FDG-PET) for postchemotherapy seminoma residual lesions: a retrospective validation of the SEMPET trial.

BACKGROUND: 2-¹8fluoro-deoxy-D-glucose positron emission tomography (FDG-PET) has been recommended in international guidelines in the evaluation of postchemotherapy seminoma residuals. Our trial was designed to validate these recommendations in a larger group of patients. PATIENTS AND METHODS: FDG-PET studies in patients with metastatic seminoma and residual masses after platinum-containing chemotherapy were correlated with either the histology of the resected lesion(s) or the clinical outcome. RESULTS: One hundred and seventy seven FDG-PET results were contributed. Of 127 eligible PET studies, 69% were true negative, 11% true positive, 6% false negative, and 15% false positive. We compared PET scans carried out before and after a cut-off level of 6 weeks after the end of the last chemotherapy cycle. PET sensitivity, specificity, negative predictive value (NPV), and positive predictive value were 50%, 77%, 91%, and 25%, respectively, before the cut-off and 82%, 90%, 95%, and 69% after the cut-off. PET accuracy significantly improved from 73% before to 88% after the cut-off (P=0.032). CONCLUSION: Our study confirms the high specificity, sensitivity, and NPV of FDG-PET for evaluating postchemotherapy seminoma residuals. When carried out at an adequate time point, FDG-PET remains a valuable tool for clinical decision-making in this clinical setting and spares patients unnecessary therapy.

Treatment of patients with relapsed and/or cisplatin-refractory metastatic germ cell tumours: an update.

Since the introduction of cisplatin-based therapy in the late 1970s, germ cell tumours (GCT) have been one of the successes in oncology with high cure rates even in patients presenting with metastatic disease. For patients with relapse after cisplatin-based therapy, treatment is still curative in approximately 50% of the cases. Management options for these patients include surgery, radiotherapy and use of conventional dose or high-dose chemotherapy (HDCT). Therefore, treatment of relapsed or refractory patients is complex and there is no uniformly accepted approach available. Data comparing conventional dose and HDCT in the first salvage therapy is limited to one randomized trial which was not able to ultimately define optimal treatment. More recently, a large retrospective analysis of nearly 1600 patients not only identified prognostic factors in relapse, but retrospectively suggested a 10-15% benefit regarding overall survival for patients receiving HDCT plus autologous stem cell transplantation over patients receiving conventional-dose chemotherapy. Prognosis in multiply relapsed and primary cisplatin-refractory patients is generally poor. Currently, a number of mechanisms of cisplatin resistance and potential drug targets like global methylation and BRAF mutation status are under investigation in refractory GCT.

Preclinical and clinical activity of sunitinib in patients with cisplatin-refractory or multiply relapsed germ cell tumors: a Canadian Urologic Oncology Group/German Testicular Cancer Study Group cooperative study.

BACKGROUND: The objective of the study was to investigate the activity of sunitinib in a cell line model and subsequently in patients with cisplatin-refractory or multiply relapsed germ cell tumors (GCT). METHODS: The effect of sunitinib on cell proliferation in cisplatin-sensitive and cisplatin-refractory GCT cell lines was evaluated after 48-h sunitinib exposure by MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay, and IC(50) (concentration that causes 50% inhibition of growth) doses were determined. Sunitinib was subsequently administered at a dose of 50 mg/day for 4 weeks followed by a 2-week break to 33 patients using a Simon two-stage design. RESULTS: Sunitinib demonstrated comparable dose-dependent growth inhibition in cisplatin-sensitive and cisplatin-resistant cell lines, with IC(50) between 3.0 and 3.8 µM. Patient characteristics were as follows: median of 2 (1-6) cisplatin-containing regimens; high-dose chemotherapy 67%; late relapse 33%; and cisplatin refractory or absolute cisplatin refractory 54%. Toxic effects included fatigue (39%), anorexia (21%), diarrhea (27%), mucositis (45%), nausea (33%), hand-foot syndrome (12%), dyspepsia (27%), and skin rash (18%). No unexpected side-effects were observed. Thirty -two of 33 patients were assessable for response. Three confirmed partial responses (PRs) and one unconfirmed PR were seen for a total response rate of 13%. Median progression-free survival (PFS) was 2 months, with a 6-month PFS rate of 11%. CONCLUSIONS: Sunitinib shows in vitro activity in cisplatin-resistant GCT cell lines. Modest clinical activity in heavily pretreated GCT patients was observed.

[Salvage treatment in germ cell tumors : high-dose chemotherapy and the impact of prognostic factors]. / Rezidivtherapie von Hodentumoren : Stellenwert der Hochdosistherapie und die Rolle von Prognosefaktoren.

The majority of patients with germ cell tumors who fail first-line treatment will still be cured. Patients without first-line chemotherapy who fail surveillance, radiotherapy, or surgery will be managed according to the treatment algorithms of their primary metastatic disease. These patients usually receive three to four cycles of cisplatin, etoposide, and bleomycin.Salvage treatment of patients who relapse after first-line chemotherapy is more complex and requires an experienced and highly specialized team. Two distinct treatment strategies can be pursued: four cycles of conventional-dose chemotherapy with cisplatin, ifosfamide, and either etoposide, paclitaxel, or vinblastine; or early intensification of first-salvage treatment using sequential high-dose chemotherapy. Salvage surgery is frequently required after completion of salvage chemotherapy to completely resect all radiologic residual manifestations. Patients with brain metastases should receive upfront whole brain radiation concurrent with salvage chemotherapy. Patients with late relapses more than 2 years after first-line treatment should receive immediate salvage surgery whenever this is technically feasible.
