Supplementary Figure S2 from High-Density Single Nucleotide Polymorphism Array Defines Novel Stage and Location-Dependent Allelic Imbalances in Human Bladder Tumors

Bladder cancer is a common disease characterized by multiple recurrences and an invasive disease course in more than 10% of patients. It is of monoclonal or oligoclonal origin and genomic instability has been shown at certain loci. We used a 10,000 single nucleotide polymorphism (SNP) array with an average of 2,700 heterozygous SNPs to detect allelic imbalances (AI) in 37 microdissected bladder tumors from 17 patients. Eight tumors represented upstaging from Ta to T1, eight from T1 to T2+, and one from Ta to T2+. The AI was strongly stage-dependent as four chromosomal arms showed AI in > 50% of Ta samples, eight in T1, and twenty-two in T2+ samples. The tumors showed stage-dependent clonality as 61.3% of AIs were reconfirmed in later T1 tumors and 84.4% in muscle-invasive tumors. Novel unstable chromosomal areas were identified at chromosomes 6q, 10p, 16q, 20p, 20q, and 22q. The tumors separated into two distinct groups, highly stable tumors (all Ta tumors) and unstable tumors (2/3 muscle-invasive). All 11 unstable tumors had lost chromosome 17p areas and 90% chromosome 8 areas affecting Netrin-1/UNC5D/MAP2K4 genes as well as others. AI was present at the TP53 locus in 10 out of 11 unstable tumors, whereas 6 had homozygous TP53 mutations. Tumor distribution pattern reflected AI as seven out of eight patients with additional upper urinary tract tumors had genomic stable bladder tumors (P < 0.05). These data show the power of high-resolution SNP arrays for defining clinically relevant AIs.

Background The Domus study, a randomized controlled trial (RCT), evaluated the effect of home-based specialized palliative care (SPC) reinforced with a psychological intervention for the patient-caregiver dyad on increasing advanced cancer patients’ time spent at home, as opposed to hospitalized, and the number of home deaths. As palliative care extends to include support for patients’ families and may thus assist caregivers and decrease demands on them, in this study we evaluated a secondary outcome, caregiver burden. Material and Methods Patients with incurable cancer and their caregivers were randomized (1:1) to care as usual or home-based SPC. Caregiver burden was assessed using the Zarit Burden Interview (ZBI) at baseline and 2, 4, 8 weeks and 6 months after randomization. Intervention effects were assessed in mixed effects models. Results A total of 258 caregivers were enrolled. Eleven per cent of informal caregivers experienced severe caregiver burden at baseline. Caregiver burden increased significantly over time in both groups (p = 0.0003), but no significant effect of the intervention was seen on overall caregiver burden (p = 0.5046) or burden subscales measuring role and personal strain. Conclusion In line with the majority of previous RCTs, the Domus intervention was not able to significantly reduce caregiver burden. Future interventions should consider targeting only caregivers reporting the greatest caregiver burden.

ObjectivesTo assess the effect of a systematic, fast-track transition from oncological treatment to specialised palliative care at home on symptom burden, to explore intervention mechanisms through patient and intervention provider characteristics and to assess long-term survival and place of death.MeasuresThe effect of a systematic, fast-track transition from oncological treatment to specialised palliative care at home on patient symptom burden was studied in the Domus randomised clinical trial. Participants had incurable cancer and limited treatment options. The intervention was provided by specialised palliative home teams (SPT) based in hospice or hospital and was enriched with a psychological intervention for patient and caregiver dyad. Symptom burden was measured with Edmonton Symptom Assessment System (ESAS-r) at baseline, 8 weeks and 6 months follow-up and analysed with mixed models. Survival and place of death was analysed with Kaplan-Meier and Fisher’s exact tests.ResultsThe study included 322 patients. Tiredness was significantly improved for the Domus intervention group at 6 months while the other nine symptom outcomes were not significantly different from the control group. Exploring the efficacy of intervention provider demonstrated significant differences in favour of the hospice SPT on four symptoms and total symptom score. Patients with children responded more favourably to the intervention. The long-term follow-up demonstrated no differences between the intervention and the control groups regarding survival or home deaths.ConclusionsThe Domus intervention may reduce tiredness. Moreover, the intervention provider and having children might play a role concerning intervention efficacy. The intervention did not affect survival or home deaths.Trial registration numberNCT01885637

Simple Summary Bladder cancer is an aggressive disease and after operation many patients are at risk of recurrence and shortened survival. Specific proteins are known to be of importance in the development of cancers. One of these proteins is the urokinase-type plasminogen activator receptor (uPAR) which exists in different forms. We here investigate the presence of the different uPAR forms in plasma from patients with bladder cancer, and we associate the elevated amount of uPAR forms with survival. We find that high levels of all uPAR forms is associated with short survival in patients with bladder cancer and suggest that this in the future might help improve handling of the disease. Abstract Urothelial carcinoma of the bladder is a highly aggressive disease characterised by a very heterogeneous clinical outcome. Despite cystectomy, patients still have a high recurrence risk and shortened survival. Urokinase-type plasminogen activator receptor (uPAR) is present in tumour tissue specimens from patients with urothelial carcinoma. The different uPAR forms in blood are strong prognostic markers in other cancer types. We investigate the presence of different uPAR forms in tumour tissue and test the hypothesis that preoperative plasma levels of the uPAR forms predict recurrence free survival, cancer specific survival, and overall survival in patients treated with cystectomy for urothelial carcinoma. Using Western blotting we analyse neoplasia and adjacent benign-appearing urothelium from randomly selected patients for the presence of intact and cleaved uPAR forms. Prospectively collected preoperative plasma samples from 107 patients who underwent radical cystectomy for urothelial carcinoma are analysed. The different uPAR forms are measured by time-resolved fluorescence immunoassays. uPAR in tumour tissue from patients with urothelial carcinoma is demonstrated in both an intact and cleaved form. The different uPAR forms in plasma are all significantly associated with both recurrence free survival, cancer specific survival, and overall survival, high concentrations predicting short survival. uPAR (I) has the strongest association with a HR of 2.56 for overall survival. In the multivariable survival analysis uPAR (I) is significantly associated with cancer specific survival and overall survival.

CONTEXT: Avoidable hospital admissions are important negative indicators of quality of end-of-life care. Specialized palliative care (SPC) may support patients remaining at home.OBJECTIVES: Therefore, the purpose of this study was to investigate if SPC at home could prevent hospital admissions in patients with incurable cancer.METHODS: These are secondary results of Domus: a randomized controlled trial of accelerated transition to SPC with psychological intervention at home (Clinicaltrials.gov: NCT01885637). Participants were patients with incurable cancer and limited antineoplastic treatment options and their caregivers. They were included from the Department of Oncology, Rigshospitalet, Denmark, between 2013 and 2016. The control group received usual care. Outcomes were hospital admissions, causes thereof, and patient and caregiver perceptions of place of care (home, hospital, etc.) at baseline, four weeks, eight weeks, and six months.RESULTS: During the study, 340 patients were randomized and 322 were included in modified intention-to-treat analyses. Overall, there were no significant differences in hospital admissions between the groups. The intervention group had more admissions triggered by worsened general health (22% vs. 16%, P = 0.0436) or unmanageable home situation (8% vs. 4%, P = 0.0119). After diagnostics, admissions were more often caused by clinical symptoms of cancer without progression in the intervention group (11% vs. 7%, P = 0.0493). The two groups did not differ significantly in overall potentially avoidable admissions. Both groups felt mostly safe about their place of care.CONCLUSION: The intervention did not prevent hospital admissions. Likely, any intervention effects were outweighed by increased identification of problems in the intervention group leading to hospital admissions. Overall, patients and caregivers felt safe in their current place of care.

Background: The present study (VINGEM) is the first randomised trial comparing vinflunine/gemcitabine (VG) to standard carboplatin/gemcitabine (CG) in patients with advanced urothelial carcinoma (aUC) ineligible for treatment with cisplatin. Patients and methods: Patients with aUC, creatinine clearance 30–60 ml/min, performance status ≤1 and no prior chemotherapy for metastatic disease were randomised to the experimental arm (vinflunine 280 or 250 mg/m2 day 1, gemcitabine 1000 mg/m2 days 1 and 8, q21 days) or the control arm (carboplatin AUC 4.5 day 1, gemcitabine 1000 mg/m2 days 1 and 8, q21 days). Primary end-point was progression-free survival (PFS). Results: Sixty-two patients were randomised; a total of 59 patients were treated (29 VG, 30 CG). There was no significant difference in PFS between the treatment arms: median 6.2 months for VG versus 6.3 months for CG (hazard ratio [HR]: 0.75, 95% confidence interval [CI]: 0.44–1.28; P = 0.293). Median overall survival was 12.5 months for VG versus 10.6 months for CG. The overall response rate (ORR) was higher in the VG arm than in the CG arm (63% versus 40%) but was not statistically significant in the intention-to-treat analysis. Furthermore, VG showed a high complete response (CR) rate, 22% versus 3% in CG. In the per-protocol group, both ORR and CR were significantly higher for VG than for CG. The most common adverse events (AEs) were fatigue, haematological toxicities, gastrointestinal disorders and nausea/vomiting. Common grade III/IV AEs were neutropenia (VG 62%, CG 43%), thrombocytopenia (VG 7%, CG 37%) and febrile neutropenia (VG 31%, CG 7%). Conclusions: The combination of VG did not improve PFS compared with standard treatment with CG in patients unfit for cisplatin due to renal impairment. The response rate of VG indicates, however, an active regimen and warrants further studies. Clinicaltrials.gov number: NCT02665039.

OBJECTIVE: Specialized palliative care (SPC) interventions increasingly include patient-caregiver dyads, but their effects on dyadic coping are unknown. We investigated whether an SPC and dyadic psychological intervention increased aspects of dyadic coping in patients with advanced cancer and their caregivers, whether dyad characteristics moderated effects and whether aspects of dyadic coping mediated significant intervention effects on caregivers' anxiety and depression.METHODS: We randomized 258 patients with incurable cancer and their caregivers to care as usual or accelerated transition from oncological treatment to home-based SPC and dyadic psychological support. In secondary outcome analyses, using mixed-effects models, we estimated intervention effects and 95% confidence intervals (CIs) for communication of stress and common coping, and moderation by dyad type and demographics. In path analyses, we investigated whether stress communication and common coping mediated intervention effects on caregivers' symptoms of anxiety and depression. (Clinicaltrials.gov NCT01885637).RESULTS: The intervention significantly increased common coping in patients and caregivers in couples (estimated difference, 0.68; 95% CI, 0.11 to 1.24) and stress communication by partner caregivers (0.97; 0.24 to 1.24). We found some support for different intervention effects for spouses and other dyads, but no evidence of mediation.CONCLUSIONS: Specialized palliative care and dyadic psychological intervention may affect aspects of dyadic coping. Common coping and stress communication did not mediate the previously found significant intervention effects on caregiver anxiety and depression, indicating that other mechanisms may have been central in the intervention.

BACKGROUND: Specialised palliative care trials often fail to address intervention effects on caregiver anxiety and depression, particularly in bereavement. We evaluate effects of specialised palliative care and dyadic psychological intervention on caregiver anxiety and depression in a randomised controlled trial (RCT).METHODS: Patients with incurable cancer and limited antineoplastic treatment options and their caregivers, recruited from a university hospital oncology department, were randomised (1:1) to care as usual or accelerated transition from oncological treatment to home-based specialised palliative care. We assessed caregivers' symptoms of anxiety and depression with the Symptom Checklist-92 up to six months after randomisation and 19 months into bereavement, and estimated intervention effects in mixed effects models.RESULTS: The 'Domus' trial enrolled 258 caregivers. The intervention significantly attenuated increases in caregivers' symptoms of anxiety overall (estimated difference, -0.12; 95% confidence interval, -0.22 to -0.01, p = 0.0266), and symptoms of depression at eight weeks (-0.17; -0.33 to -0.02; p = 0.0314), six months (-0.27; -0.49 to -0.05; p = 0.0165), and in bereavement at two weeks (-0.28; -0.52 to -0.03; p = 0.0295) and two months (-0.24; -0.48 to -0.01; p = 0.0448).CONCLUSIONS: This first RCT evaluating specialised palliative care with dyadic psychological support significantly attenuated caregiver anxiety and depression before and during bereavement. (Clinicaltrials.gov: NCT01885637).

Background: The focus of specialized palliative care is to improve quality of life for patients with incurable cancer and their relatives including an increased opportunity to make their own choice of place of care and death. Aim: To investigate whether a systematic fast-track transition from oncological treatment to specialized palliative care at home for patients with incurable cancer reinforced with a psychological dyadic intervention could result in more time spent at home and death at home. Secondary aims were to investigate effects on quality of life, symptomatology and survival. Design: A prospective, single-centre, randomized controlled trial ( Clinicaltrials.gov : NCT01885637). Setting/participants: In all, 340 patients with incurable cancer and no or limited antineoplastic treatment options. Results: No statistically significant difference was found regarding number of deaths (4%, p = 0.460) and time spent at home (3%, p = 0.491). The secondary outcomes indicated that the intervention resulted in improved quality of life (−11.6 ± 25.5, p = 0.005, effect size = −0.44, 95% confidence interval = −0.77; −0.11), social functioning (−15.8 ± 31.4, p = 0.001, effect size = −0.50, 95% confidence interval = −0.84; −0.17) and emotional functioning (−9.1 ± 21.2, p = 0.039, effect size = −0.43, 95% confidence interval = −0.76; −0.10) after 6 months. A linear mixed-effect regression model confirmed a possible effect on emotional and social functioning at 6 months. Regarding survival, no differences were found between groups ( p = 0.605). No adverse effects were seen as consequence of the intervention. Conclusions: The main findings indicated that the intervention had no effect on time spent at home or place of death. However, the intervention resulted in a weak improvement of quality of life, social functioning and emotional functioning after 6 months.

Objective:Patients with incurable cancer and their informal caregivers have numerous psychological and psychosocial needs. Many of these patients wish to receive their care and die at home. Few home-based specialized palliative care (SPC) interventions systematically integrate psychological support. We present a psychological intervention for patient–caregiver dyads developed for an ongoing randomized controlled trial (RCT) of home-based SPC, known as Domus, as well as the results of an assessment of its acceptability and feasibility.Method:The Domus model of SPC for patients with incurable cancer and their caregivers offered systematic psychological assessment and dyadic intervention as part of interdisciplinary care. Through accelerated transition to SPC, the aim of the model was to enhance patients' chances of receiving care and dying at home. Integration of psychological support sought to facilitate this goal by alleviating distress in patients and caregivers. Psychologists provided needs-based sessions based on existential-phenomenological therapy. Feasibility and acceptability were investigated by examining enrollment, nonparticipation, and completion of psychological sessions.Results:Enrollment in the RCT and uptake of the psychological intervention indicated that it was feasible and acceptable to patients and caregivers. The strengths of the intervention included its focus on dyads, psychological distress, and existential concerns, as well as interdisciplinary collaboration and psychological interventions offered according to need. Its main limitation was a lack of an intervention for other family members.Significance of Results:Our results show that psychological intervention can be systematically integrated into SPC and that it appears feasible to provide dyadic needs-based sessions with an existential therapeutic approach. The Domus RCT will provide evidence of the efficacy of a novel model of multidisciplinary SPC.

Purpose: The purposes of the present study were to classify the palliative care population (PCP) in a comprehensive cancer centre by using information on antineoplastic treatment options and to analyse associations between socio-demographic factors, cancer diagnoses, treatment characteristics and receiving specialist palliative care (SPC). Methods: This is a cross-sectional screening study of patients with cancer in the Department of Oncology, Rigshospitalet, Copenhagen University Hospital for 6 months. Patients were assessed to be included in the DOMUS study: a randomised controlled trial of accelerated transition to SPC at home (NCT01885637). The PCP was classified as patients with incurable cancer and limited or no antineoplastic treatment options. Patients with performance status 2–4 were further classified as the essential palliative care population (EPCP). Results: During the study period, 3717 patients with cancer were assessed. The PCP comprised 513 patients yielding a prevalence of 14 %. The EPCP comprised 256 patients (7 %). The EPCP was older, more likely inpatients, had a higher comorbidity burden and 38 % received SPC. Women, patients without caregivers and patients with breast cancer were more likely to receive SPC. Conclusions: By using objective criteria from clinical data and systematic screening, the observed prevalence of the PCP of 14 % may be generalisable to comprehensive cancer centres with similar composition of cancer diagnoses.

The optimal treatment strategy for patients with clinical stage I (CS-1) seminoma is controversial. The objective of the current study was to evaluate the outcomes for patients considered to be at high risk of disease recurrence with a tumor size ≥6 cm. Patients were treated with either adjuvant radiotherapy (RT) or followed with surveillance.From the Danish Testicular Cancer database, the authors identified 473 patients with CS-1 seminoma with a tumor size ≥6 cm. Of these, 254 patients underwent adjuvant RT and 219 were followed with surveillance. Cumulative incidence function was applied to estimate the risk of disease recurrence, risk of second malignant neoplasm, and risk of receiving1 line of treatment. Survival of the 2 groups was compared with the log-rank test and Cox model including age at diagnosis.No significant differences were found with regard to overall survival or risk of a second malignant neoplasm. Patients undergoing adjuvant RT received more treatments per patient than patients followed with surveillance, but there was no significant difference noted with regard to the risk of receiving1 line of treatment. The 10-year cumulative incidence of disease recurrence was 32% versus 2.8%, respectively, for patients followed with surveillance and adjuvant RT. In patients followed with surveillance who developed disease recurrence, there was a high incidence of second recurrences after RT.The 10-year overall survival was found to be similar irrespective of primary treatment. Adjuvant RT was found to effectively reduce the rate of disease recurrence but resulted in the overtreatment of approximately two-thirds of the patients. The high incidence of second disease recurrences after RT in the patients followed with surveillance needs be addressed in future studies. Cancer 2017;123:1212-1218. © 2016 American Cancer Society.

BACKGROUND: Comprehensive data on late relapse (LR) and very LR (VLR) in patients with clinical stage I (CS-1) testicular cancer followed on surveillance are missing. These data are essential for planning optimal follow-up.OBJECTIVE: Assess incidence and outcome of LR (>2 yr) and VLR (>5 yr) in a large cohort of CS-1 surveillance patients, and examine differences in the clinical characteristics of patients with early relapse (ER), LR, and VLR.DESIGN, SETTING, AND PARTICIPANTS: CS-1 surveillance patients diagnosed between 1984 and 2007 were identified from the retrospective Danish Testicular Cancer (DaTeCa) database.OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We estimated survival and relapse probabilities and compared the results using log-rank tests and Cox regression analyses. We compared differences in patient characteristics by using χ(2), Fisher exact, and Mann-Whitney tests.RESULTS AND LIMITATIONS: Our study included 3366 (2000 seminoma and 1366 nonseminoma) patients. Median follow-up was 15 yr. Five-year conditional risk of LR was 5.0% and 2.1% for seminoma and nonseminoma patients, respectively. There were no significant differences in disease-specific or overall survival when comparing the LR(VLR) and ER patients by log-rank, but Cox regression adjusted for age showed a significant effect of time to relapse on survival for seminoma patients. Apart from significantly more ER nonseminoma patients with elevated human chorionic gonadotropin at relapse, there were no significant differences in patient characteristics at orchiectomy or relapse. Limitations include retrospective design and exclusion of patients who had been offered adjuvant therapy.CONCLUSIONS: The risk of VLR is minimal, and the patients carry a good prognosis. Patient characteristics of CS-1 surveillance patients with LR(VLR) do not differ significantly from patients with ER.PATIENT SUMMARY: We compared stage I testicular cancer surveillance patients with early relapse (ER) versus late relapse (LR; >2 yr). LR patients as a group did no worse than ER patients, although increased time to relapse was negatively associated with survival for seminoma patients.

The objective of the present study was to confirm the expression and localisation pattern of the urokinase-type plasminogen activator receptor (uPAR) focusing on its possible clinical relevance in patients with urothelial neoplasia of the bladder. uPAR is a central molecule in tissue remodelling during cancer invasion and metastasis and is an established prognostic marker in various cancer diseases other than bladder cancer. Formalin-fixed and paraffin-embedded tumour-tissue blocks from 186 patients treated with radical cystectomy were analysed. uPAR expression was scored as either negative or positive as well as by the actual score. Separate scores were obtained for cancer cells, macrophages and myofibroblasts at the invasive front and in tumour core. We were able to confirm, in an independent patient cohort, the tissue expression and localisation pattern of uPAR as investigated by Immunohistochemistry as well as a significant association between uPAR positivity and increasing tumour stage and tumour grade. This demonstrates the robustness of our previous and current findings. In addition the association between uPAR positive myofibroblasts and poor survival was reproduced. The highest hazard ratios for survival were seen for uPAR positive myofibroblasts both at the invasive front and in tumour core. Evaluating uPAR expression by the actual score showed a significant association between uPAR positive myofibroblasts in tumour core and an increased risk of cancer specific mortality. Our investigations have generated new and valuable biological information about the cell types being involved in tumour invasion and progression through the plasminogen activation system.

Objectives To evaluate the expression-and localization pattern of the urokinase-type plasminogen activator receptor (uPAR), focusing on its clinical implications in patients with urothelial neoplasia of the bladder treated with radical cystectomy. uPAR is a central molecule in tissue remodeling during cancer invasion and metastasis and is an established prognostic marker in cancer. The expression and localization of uPAR and its prognostic significance is only limitedly investigated in urothelial bladder neoplasia. Materials and methods The expression-and localization pattern of uPAR was investigated in formalin-fixed paraffin-embedded tumor tissue from 149 patients treated with radical cystectomy between 1988 and 2005. uPAR expression was determined by immunohistochemistry and scored as either negative or positive. Separate values were obtained for cancer cells, macrophages, and myofibroblasts at the invasive front and tumor core, respectively. Statistical analyses were performed to evaluate the association of uPAR localization and score with clinicopathologic covariates and survival. Results uPAR positivity was seen in 122/137 (89%) and 118/149 (74%) of the neoplasias at the invasive front and tumor core, respectively. uPAR was primarily expressed by myofibroblasts and macrophages in the surrounding stroma as well as some cancer cells. A significant association between uPAR positivity and T-stage as well as grade was found for all 3 cell types in tumor core (P≤0.04 for all comparisons). In univariate analysis, the uPAR positive group had a shorter survival than the uPAR negative group (hazard ratio = 2.39; 95% CI: 1.15–5.01; P = 0.020). Conclusions The expression of uPAR is a possible prognostic marker that could be useful in identification of patients with aggressive, highly invasive tumors that could benefit from additional chemotherapy or more intensive follow-up after cystectomy.
