A biomarker panel predicts recurrence-free survival in ulcerated primary cutaneous melanoma.

BACKGROUND: Ulceration is an independent adverse prognostic factor in cutaneous malignant melanoma (CMM). There is, however, a need for additional prognostic markers to identify patients with ulcerated stage I-II CMM who have a high-risk for recurrence. The aim of this study was to examine the prognostic impact of BRAF mutation, proliferation and presence of tumour infiltrating lymphocytes (TILs) in primary ulcerated CMM. MATERIAL AND METHODS: We have used a consecutive cohort consisting of 71 primary ulcerated CMM (T1b-T4b). BRAF mutation was detected using Cobas test and pyrosequencing. Protein expression of the proliferation marker Ki67 was analysed using immunohistochemistry. Presence of TILs was evaluated in representative hematoxylin-eosin stained formalin-fixed paraffin-embedded tumour sections. RESULTS: Proportion of BRAF mutated alleles, proliferation and presence of TILs all had a statistically significant impact on recurrence free survival in univariate analyses (HR 2.44, 95% CI 1.23-4.84, p = 0.011; HR 2.66, 95% CI 1.32-5.35, p = 0.006 respectively HR 0.48, 95% CI 0.24-0.98, p = 0.045). A trend test found a statistically significant decrease in the proportion of recurrence by including the three favourable factors (BRAF wildtype/low proportion of BRAF mutated alleles, low proliferation and high presence of TILs) (p = 0.0004). When at least two out of three factors were present there was a statistically significant association with longer recurrence free survival in the multivariate analysis (HR 0.30, 95% CI 0.15-0.61, p = 0.001) when adjusted for Breslow thickness, an established independent prognostic marker for CMM. CONCLUSION: Thus, this panel of markers could be an interesting novel concept for predicting the clinical outcome in patients with high-risk stage I-II ulcerated CMM.

Birth cohort-specific trends of sun-related behaviors among individuals from an international consortium of melanoma-prone families.

BACKGROUND: Individuals from melanoma-prone families have similar or reduced sun-protective behaviors compared to the general population. Studies on trends in sun-related behaviors have been temporally and geographically limited. METHODS: Individuals from an international consortium of melanoma-prone families (GenoMEL) were retrospectively asked about sunscreen use, sun exposure (time spent outside), sunburns, and sunbed use at several timepoints over their lifetime. Generalized linear mixed models were used to examine the association between these outcomes and birth cohort defined by decade spans, after adjusting for covariates. RESULTS: A total of 2407 participants from 547 families across 17 centers were analyzed. Sunscreen use increased across subsequent birth cohorts, and although the likelihood of sunburns increased until the 1950s birth cohort, it decreased thereafter. Average sun exposure did not change across the birth cohorts, and the likelihood of sunbed use increased in more recent birth cohorts. We generally did not find any differences in sun-related behavior when comparing melanoma cases to non-cases. Melanoma cases had increased sunscreen use, decreased sun exposure, and decreased odds of sunburn and sunbed use after melanoma diagnosis compared to before diagnosis. CONCLUSIONS: Although sunscreen use has increased and the likelihood of sunburns has decreased in more recent birth cohorts, individuals in melanoma-prone families have not reduced their overall sun exposure and had an increased likelihood of sunbed use in more recent birth cohorts. These observations demonstrate partial improvements in melanoma prevention and suggest that additional intervention strategies may be needed to achieve optimal sun-protective behavior in melanoma-prone families.

High expression of ID1 in monocytes is strongly associated with phenotypic and functional MDSC markers in advanced melanoma.

The efficacy of immunotherapies for malignant melanoma is severely hampered by local and systemic immunosuppression mediated by myeloid-derived suppressor cells (MDSC). Inhibitor of differentiation 1 (ID1) is a transcriptional regulator that was shown to be centrally involved in the induction of immunosuppressive properties in myeloid cells in mice, while it was overexpressed in CD11b+ cells in the blood of late-stage melanoma patients. Therefore, we comprehensively assessed ID1 expression in PBMC from stage III and IV melanoma patients, and studied ID1 regulation in models for human monocyte differentiation towards monocyte-derived dendritic cells. A highly significant elevation of ID1 was observed in CD33+CD11b+CD14+HLA-DRlow monocytic MDSC in the blood of melanoma patients compared to their HLA-DRhigh counterparts, while expression of ID1 correlated positively with established MDSC markers S100A8/9 and iNOS. Moreover, expression of ID1 in monocytes significantly decreased in PBMC samples taken after surgical removal of melanoma metastases, compared to those taken before surgery. Finally, maturation of monocyte-derived DC coincided with a significant downregulation of ID1. Together, these data indicate that increased ID1 expression is strongly associated with expression of phenotypic and immunosuppressive markers of monocytic MDSC, while downregulation is associated with a more immunogenic myeloid phenotype. As such, ID1 may be an additional phenotypic marker for monocytic MDSC. Investigation of ID1 as a pharmacodynamic biomarker or its use as a target for modulating MDSC is warranted.

TRIM study protocol - a prospective randomized multicenter Trial to assess the Role of Imaging during follow-up after radical surgery of stage IIB-C and III cutaneous malignant Melanoma.

BACKGROUND: The incidence of cutaneous malignant melanoma (CMM) is increasing worldwide. In Sweden, over 4600 cases were diagnosed in 2018. The prognosis after radical surgery varies considerably with tumor stage. In recent years, new treatment options have become available for metastatic CMM. Early onset of treatment seems to improve outcome, which suggests that early detection of recurrent disease should be beneficial. Consequently, in several countries imaging is a part of the routine follow-up program after surgery of high risk CMM. However, imaging has drawbacks, including resources required (costs, personnel, equipment) and the radiation exposure. Furthermore, many patients experience anxiety in waiting for the imaging results and investigations of irrelevant findings is another factor that also could cause worry and lead to decreased quality of life. Hence, the impact of imaging in this setting is important to address and no randomized study has previously been conducted. The Swedish national guidelines stipulate follow-up for 3 years by clinical examinations only. METHODS: The TRIM study is a prospective randomized multicenter trial evaluating the potential benefit of imaging and blood tests during follow-up after radical surgery for high-risk CMM, compared to clinical examinations only. Primary endpoint is overall survival (OS) at 5 years. Secondary endpoints are survival from diagnosis of relapse and health-related quality of life (HRQoL). Eligible for inclusion are patients radically operated for CMM stage IIB-C or III with sufficient renal function for iv contrast-enhanced CT and who are expected to be fit for treatment in case of recurrence. The planned number of patients is > 1300. Patients are randomized to clinical examinations for 3 years +/- whole-body imaging with CT or FDG-PET/CT and laboratory tests including S100B protein and LDH. This academic study is supported by the Swedish Melanoma Study Group. DISCUSSION: This is the first randomized prospective trial on the potential benefit of imaging as a part of the follow-up scheme after radical surgery for high-risk CMM. RESULTS: The first patient was recruited in June 2017 and as of April 2020, almost 500 patients had been included at 19 centers in Sweden. TRIAL REGISTRATION: ClinicalTrials.gov , NCT03116412 . Registered 17 April 2017, https://clinicaltrials.gov/ct2/show/study/NCT03116412.

Leadership in specialist palliative home care teams: A qualitative study.

AIM: The aim of this study was to describe team leaders' experiences of facilitators and barriers of leadership in specialist palliative home care teams. BACKGROUND: For effective teamwork in specialist palliative care, leadership is crucial; however, defining and agreeing on what leadership comprises may be challenging. In palliative care, teamwork is recognized as imperative for multiprofessional perspectives to meet dying patients' and families' needs. METHODS: Qualitative interviews with 13 team leaders in specialist palliative home care were performed, using the Pettigrew and Whipp framework, and analysed with directed content analysis. RESULTS: Team leaders' experiences of conditions influencing the organisation and delivery of specialist palliative home care is multifaceted and leaders seem conflicted in their approach to the multiple levels of leadership, vision and responsibilities. CONCLUSION: Team leaders in specialist palliative home care described goals of care on differing levels and, for some, fiscal restraints and external pressures influenced their vision and leadership. Team leaders experienced challenges of leadership in relation to organisational issues, feeling burdened by responsibilities, budget restraints and team size. IMPLICATIONS FOR NURSING MANAGEMENT: Team leadership is demanding and complex. In specialist palliative home care, affirming values and enabling vision during times of fiscal strain and external pressures, is challenging. For successful leadership that develops both individuals and the health care team, leaders are recommended to adapt the leadership style to the present situation surrounding the team.

Identification of the optimal combination dosing schedule of neoadjuvant ipilimumab plus nivolumab in macroscopic stage III melanoma (OpACIN-neo): a multicentre, phase 2, randomised, controlled trial.

BACKGROUND: The outcome of patients with macroscopic stage III melanoma is poor. Neoadjuvant treatment with ipilimumab plus nivolumab at the standard dosing schedule induced pathological responses in a high proportion of patients in two small independent early-phase trials, and no patients with a pathological response have relapsed after a median follow up of 32 months. However, toxicity of the standard ipilimumab plus nivolumab dosing schedule was high, preventing its broader clinical use. The aim of the OpACIN-neo trial was to identify a dosing schedule of ipilimumab plus nivolumab that is less toxic but equally effective. METHODS: OpACIN-neo is a multicentre, open-label, phase 2, randomised, controlled trial. Eligible patients were aged at least 18 years, had a WHO performance status of 0-1, had resectable stage III melanoma involving lymph nodes only, and measurable disease according to the Response Evaluation Criteria in Solid Tumors version 1.1. Patients were enrolled from three medical centres in Australia, Sweden, and the Netherlands, and were randomly assigned (1:1:1), stratified by site, to one of three neoadjuvant dosing schedules: group A, two cycles of ipilimumab 3 mg/kg plus nivolumab 1 mg/kg once every 3 weeks intravenously; group B, two cycles of ipilimumab 1 mg/kg plus nivolumab 3 mg/kg once every 3 weeks intravenously; or group C, two cycles of ipilimumab 3 mg/kg once every 3 weeks directly followed by two cycles of nivolumab 3 mg/kg once every 2 weeks intravenously. The investigators, site staff, and patients were aware of the treatment assignment during the study participation. Pathologists were masked to treatment allocation and all other data. The primary endpoints were the proportion of patients with grade 3-4 immune-related toxicity within the first 12 weeks and the proportion of patients achieving a radiological objective response and pathological response at 6 weeks. Analyses were done in all patients who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, number NCT02977052, and is ongoing with an additional extension cohort and to complete survival analysis. FINDINGS: Between Nov 24, 2016 and June 28, 2018, 105 patients were screened for eligibility, of whom 89 (85%) eligible patients were enrolled and randomly assigned to one of the three groups. Three patients were excluded after randomisation because they were found to be ineligible, and 86 received at least one dose of study drug; 30 patients in group A, 30 in group B, and 26 in group C (accrual to this group was closed early upon advice of the Data Safety Monitoring Board on June 4, 2018 because of severe adverse events). Within the first 12 weeks, grade 3-4 immune-related adverse events were observed in 12 (40%) of 30 patients in group A, six (20%) of 30 in group B, and 13 (50%) of 26 in group C. The difference in grade 3-4 toxicity between group B and A was -20% (95% CI -46 to 6; p=0·158) and between group C and group A was 10% (-20 to 40; p=0·591). The most common grade 3-4 adverse events were elevated liver enzymes in group A (six [20%)]) and colitis in group C (five [19%]); in group B, none of the grade 3-4 adverse events were seen in more than one patient. One patient (in group A) died 9·5 months after the start of treatment due to the consequences of late-onset immune-related encephalitis, which was possibly treatment-related. 19 (63% [95% CI 44-80]) of 30 patients in group A, 17 (57% [37-75]) of 30 in group B, and nine (35% [17-56]) of 26 in group C achieved a radiological objective response, while pathological responses occurred in 24 (80% [61-92]) patients in group A, 23 (77% [58-90]) in group B, and 17 (65% [44-83]) in group C. INTERPRETATION: OpACIN-neo identified a tolerable neoadjuvant dosing schedule (group B: two cycles of ipilimumab 1 mg/kg plus nivolumab 3 mg/kg) that induces a pathological response in a high proportion of patients and might be suitable for broader clinical use. When more mature data confirm these early observations, this schedule should be tested in randomised phase 3 studies versus adjuvant therapies, which are the current standard-of-care systemic therapy for patients with stage III melanoma.

Targeting CDK2 overcomes melanoma resistance against BRAF and Hsp90 inhibitors.

Novel therapies are undergoing clinical trials, for example, the Hsp90 inhibitor, XL888, in combination with BRAF inhibitors for the treatment of therapy-resistant melanomas. Unfortunately, our data show that this combination elicits a heterogeneous response in a panel of melanoma cell lines including PDX-derived models. We sought to understand the mechanisms underlying the differential responses and suggest a patient stratification strategy. Thermal proteome profiling (TPP) identified the protein targets of XL888 in a pair of sensitive and unresponsive cell lines. Unbiased proteomics and phosphoproteomics analyses identified CDK2 as a driver of resistance to both BRAF and Hsp90 inhibitors and its expression is regulated by the transcription factor MITF upon XL888 treatment. The CDK2 inhibitor, dinaciclib, attenuated resistance to both classes of inhibitors and combinations thereof. Notably, we found that MITF expression correlates with CDK2 upregulation in patients; thus, dinaciclib would warrant consideration for treatment of patients unresponsive to BRAF-MEK and/or Hsp90 inhibitors and/or harboring MITF amplification/overexpression.

Estimating CDKN2A mutation carrier probability among global familial melanoma cases using GenoMELPREDICT.

BACKGROUND: Although rare in the general population, highly penetrant germline mutations in CDKN2A are responsible for 5%-40% of melanoma cases reported in melanoma-prone families. We sought to determine whether MELPREDICT was generalizable to a global series of families with melanoma and whether performance improvements can be achieved. METHODS: In total, 2116 familial melanoma cases were ascertained by the international GenoMEL Consortium. We recapitulated the MELPREDICT model within our data (GenoMELPREDICT) to assess performance improvements by adding phenotypic risk factors and history of pancreatic cancer. We report areas under the curve (AUC) with 95% confidence intervals (CIs) along with net reclassification indices (NRIs) as performance metrics. RESULTS: MELPREDICT performed well (AUC 0.752, 95% CI 0.730-0.775), and GenoMELPREDICT performance was similar (AUC 0.748, 95% CI 0.726-0.771). Adding a reported history of pancreatic cancer yielded discriminatory improvement (P < .0001) in GenoMELPREDICT (AUC 0.772, 95% CI 0.750-0.793, NRI 0.40). Including phenotypic risk factors did not improve performance. CONCLUSION: The MELPREDICT model functioned well in a global data set of familial melanoma cases. Adding pancreatic cancer history improved model prediction. GenoMELPREDICT is a simple tool for predicting CDKN2A mutational status among melanoma patients from melanoma-prone families and can aid in directing these patients to receive genetic testing or cancer risk counseling.

What happened and why? A programme theory-based qualitative evaluation of a healthcare-academia partnership reform in primary care.

BACKGROUND: There is increasing interest in and demands for partnerships between academia and healthcare practices. Few empirical studies have described the influence of such partnerships from a practice perspective. The purpose of this study was to evaluate the impact of a reform launched to increase integration between primary care and academia and to identify potential reasons for why the observed impact occurred in three areas targeted by the reform: research, student education, and continued professional development. METHODS: The study was conducted in Stockholm County, the largest healthcare region in Sweden, at the introduction of a partnership between primary care and academia, including eight coordinating centres and approximately 500 surrounding primary care units. A programme theory-based qualitative approach to evaluation was used, building on document analysis, and in-depth interviews with the centre managers (n = 6) and coordinators (n = 8) conducted 42-66 months after the initiation of the reform. RESULTS: The analysis showed that the reform had some impact on all three areas targeted by the reform: research, student education, and continued professional development. The input that contributed most extensively to the impact was the establishment of facilitating roles. Most changes occurred at the coordinating centres and primarily in the area of student education. The effect on student education was primarily due to having prior experience in this area and perceptions of timely benefits of students to care practice. CONCLUSIONS: Partnerships between primary care and academia hold the potential of practice impact. To increase integration between primary care and academia, the components of the integration must be understandable and relevant for primary care practitioners, and importantly, compliant with delivery of primary care.

Implementation of a national policy for improving health and social care: a comparative case study using the Consolidated Framework for Implementation Research.

BACKGROUND: Comprehensive policies are becoming common for addressing wicked problems in health and social care. Success of these policies often varies between target organizations. This variation can often be attributed to contextual factors. However, there is a lack of knowledge about the conditions for successful policy implementation and how context influences this process. The aim of this study was to investigate county-level actors' perspectives on the implementation of a comprehensive national policy in three Swedish counties. The policy focused on developing quality of care for elderly based on the use of national quality registries (NQRs) and to improve coordination of care. METHODS: A comparative case study approach was used. Data was collected longitudinally through documents and interviews. The Consolidated Framework for Implementation Research (CFIR) guided the analysis. RESULTS: All three counties shared the view that the policy addressed important issues. Still, there was variation regarding how it was perceived and managed. Adaptable features-i.e., NQRs and improvement coaches-were perceived as relevant and useful. However, the counties differed in their perceptions of another policy component-i.e., senior management program-as an opportunity or a disturbance. This program, while tackling complex issues of collaboration, fell short in recognizing the counties' pre-existing conditions and needs and also offered few opportunities for adaptations. Performance bonuses and peer pressure were strong incentives for all counties to implement the policy, despite the poor fit of policy content and local context. CONCLUSIONS: Comprehensive health policies aiming to address wicked problems have better chances of succeeding if the implementation includes assessments of the target organizations' implementation capacity as well as the implicit quid pro quos involved in policy development. Special attention is warranted regarding the use of financial incentives when dealing with wicked problems since the complexity makes it difficult to align incentives with the goals and to assess potential consequences. Other important aspects in the implementation of such policies are the use of collaborative approaches to engage stakeholders with differing perspectives, and the tailoring of policy communication to facilitate shared understanding and commitment.

Team type, team maturity and team effectiveness in specialist palliative home care: an exploratory questionnaire study.

To meet complex needs in persons and families within specialist palliative care, care team members are expected to work together in performing a comprehensive assessment of patient needs. Team type (how integrated team members work) and team maturity (group development) have been identified as components in team effectiveness and productivity. The aim of the study reported in this paper was to identify team types in specialist palliative care in Sweden, and to explore associations between team type, team maturity and team effectiveness in home care teams. A national web-based survey of team types, based on Thylefors questionnaire, and a survey of healthcare professionals using the Group Development Questionnaire (GDQ-SE3) to assess team developmental phase, effectiveness and productivity were used in an exploratory cross-sectional design. The participants were: Specialist palliative care teams in Sweden registered in the Palliative Care Directory (n = 77), and members of 11 specialist palliative home care teams. Teams comprised physicians, registered nurses, social workers, physiotherapists and/or occupational therapists, full-or part-time. Our national web survey results showed that the 77 investigated teams had existed from 7 to 21 years, were foremost of medium size and functioned as inter- or transprofessional teams. Results from the 61 HCPs, representing 11 teams, indicated that more mature teams tended to work in an integrated manner, rather than in parallel. The effectiveness ratio varied from 52% to 86% in teams. Recommendations arising from our findings include the need for clarification of team goals and professional roles together with prioritizing the development of desirable psychosocial traits and team processes in clinical settings.

Actions helping expressed or anticipated needs: Patients with advanced cancer and their family caregivers' experiences of specialist palliative home care teams.

Patients with advanced cancer and family caregivers in palliative care face physical, psychological, social and existential challenges, much of the time home alone. Specialist palliative home care team services can be instrumental for sense of security in an uncertain situation. The aim of this study was to describe patients' and family caregivers' experiences of specialist palliative home care team actions that are identified by the participants as helping or hindering interventions. Six patients and seven family caregivers were interviewed using the enhanced critical incident technique. Ninety-five critical incidents and wish list items were identified. Providing adequate resources, keeping promises and being reliable, and creating partnerships are actions by specialist palliative care teams that patients and family caregivers experienced as helping in meeting expressed or anticipated needs in patients and family caregivers. Being reliable and including patients and family caregivers in partnerships help to continue with daily life, even though death may be close. Unmet needs resulted in experiences of disrespect or violation of personal space/integrity.

Leading top-down implementation processes: a qualitative study on the role of managers.

BACKGROUND: Leadership has been identified as an influential factor in implementation processes in healthcare organizations. However, the processes through which leaders affect implementation outcomes are largely unknown. The purpose of this study is to analyse how managers interpret and make sense of a large scale top-down implementation initiative and what implications this has for the implementation process. This was studied at the implementation of an academic primary healthcare initiative covering 210 primary healthcare centres in central Sweden. The aim of the initiative was to integrate research and education into regular primary healthcare services. METHODS: The study builds on 16 in-depth individual semi-structured interviews with all managers (n = 8) who had operative responsibility for the implementation. Each manager was interviewed twice during the initial phase of the implementation. Data were analysed using a thematic approach guided by theory on managerial role taking based on the Transforming Experience Framework. RESULTS: How the managers interpreted and made sense of the implementation task built on three factors: how they perceived the different parts of the initiative, how they perceived themselves in relation to these parts, and the resources available for the initiative. Based on how they combined these three factors the managers chose to integrate or separate the different parts of the initiative in their management of the implementation process. CONCLUSIONS: This research emphasizes that managers in healthcare seem to have a substantial impact on how and to what extent different tasks are addressed and prioritized in top-down implementation processes. This has policy implications. To achieve intended implementation outcomes, the authors recognize the necessity of an early and on-going dialogue about how the implementation is perceived by the managers responsible for the implementation.

Understanding the dynamics of sustainable change: A 20-year case study of integrated health and social care.

BACKGROUND: Change initiatives face many challenges, and only a few lead to long-term sustainability. One area in which the challenge of achieving long-term sustainability is particularly noticeable is integrated health and social care. Service integration is crucial for a wide range of patients including people with complex mental health and social care needs. However, previous research has focused on the initiation, resistance and implementation of change, while longitudinal studies remain sparse. The objective of this study was therefore to gain insight into the dynamics of sustainable changes in integrated health and social care through an analysis of local actions that were triggered by a national policy. METHODS: A retrospective and qualitative case-study research design was used, and data from the model organisation's steering-committee minutes covering 1995-2015 were gathered and analysed. The analysis generated a narrative case description, which was mirrored to the key elements of the Dynamic Sustainability Framework (DSF). RESULTS: The development of inter-sectoral cooperation was characterized by a participatory approach in which a shared structure was created to support cooperation and on-going quality improvement and learning based on the needs of the service user. A key management principle was cooperation, not only on all organisational levels, but also with service users, stakeholder associations and other partner organisations. It was shown that all these parts were interrelated and collectively contributed to the creation of a structure and a culture which supported the development of a dynamic sustainable health and social care. CONCLUSION: This study provides valuable insights into the dynamics of organizational sustainability and understanding of key managerial actions taken to establish, develop and support integration of health and social care for people with complex mental health needs. The service user involvement and regular reviews of service users' needs were essential in order to tailor services to the needs. Another major finding was the importance of continuously adapting the content of the change to suit its context. Hence, continuous refinement of the change content was found to be more important than designing the change at the pre-implementation stage.

Enhancing policy implementation to improve healthcare practices: The role and strategies of hybrid national-local support structures.

BACKGROUND: In this study, we followed a national initiative to enhance the use of quality indicators gathered in national quality registries (NQRs) for improvement of clinical practices in Swedish healthcare, more specifically by investigating the support strategies of regional support centers with national and local missions. The aim was to increase knowledge on the role, challenges, and strategies of support structures with mixed and complex missions in the healthcare system. METHODS: Documents and 25 semistructured interviews with staff at 6 regional support centers, ie, quality registry centers, formed this multiple case study. Data were analyzed using conventional content analysis. RESULTS: The centers' strategies varied from developing the NQRs to become more suitable for improvement to supporting healthcare's use of NQRs, from the use of task to process-oriented support strategies, and from taking on national responsibilities to responding to local initiatives. All quality registry centers engaged in initiatives inspired by the Breakthrough Series approach. Some used preexisting change concepts or collaborated with local development units. A main challenge was to overcome a lack of formal mandate to act in the healthcare organizations they served. CONCLUSIONS: Support functions with mixed and complex missions have to use a variation of strategies to reach relevant actors and achieve changes. This study provides valuable input for policy and decision-makers on the support strategies used and challenges of support functions with complex missions situated in-between national and local levels of the healthcare system, here denoted hybrid national-local support structures.

Factors influencing early stage healthcare-academia partnerships.

Purpose The purpose of this paper is to explore factors influencing early implementation and intermediate outcomes of a healthcare-academia partnership in a primary healthcare setting. Design/methodology/approach The Academic Primary Healthcare Network (APHN) initiative was launched in 2011 in Stockholm County, Sweden and included 201 primary healthcare centres. Semi-structured interviews were conducted in 2013-2014 with all coordinating managers ( n=8) and coordinators ( n=4). A strategic change model framework was used to collect and analyse data. Findings Several factors were identified to aid early implementation: assignment and guidelines that allowed flexibility; supportive management; dedicated staff; facilities that enabled APHN actions to be integrated into healthcare practice; and positive experiences from research and educational activities. Implementation was hindered by: discrepancies between objectives and resources; underspecified guidelines that trigger passivity; limited research and educational activities; a conflicting non-supportive reimbursement system; limited planning; and organisational fragmentation. Intermediate outcomes revealed that various actions, informed by the APHN assignment, were launched in all APHNs. Practical implications The findings can be rendered applicable by preparing stakeholders in healthcare services to optimise early implementation of healthcare-academia partnerships. Originality/value This study increases understanding of interactions between factors that influence early stage partnerships between healthcare services and academia in primary healthcare settings.

Primary tumor sites in relation to ultraviolet radiation exposure and skin visibility correlate with survival in cutaneous melanoma.

The prognostic value of detailed anatomic site and ultraviolet radiation (UVR) exposure patterns has not been fully determined in cutaneous melanoma. Thus, we reviewed medical records for detailed site in a population-based retrospective Swedish patient cohort diagnosed with primary invasive melanoma 1976-2003 (n = 5,973). We followed the patients from date of diagnosis until death, emigration or December 31st 2013, and evaluated melanoma-specific survival by subsite in a multivariable regression model adjusting for established prognostic factors. We found that melanoma on chronic UVR exposure sites (face, dorsum of hands; adjusted HR 0.6; CI 0.4-0.7) and moderately intermittent UVR sites (lateral arms, lower legs, dorsum of feet; HR 0.7; CI 0.6-0.8) were associated with a favorable prognosis compared with highly intermittent sites (chest, back, neck, shoulders and thighs). Further, melanoma on poorly visible skin sites upon self-examination (scalp, retroauricular area, back, posterior upper arms and thighs, buttocks, pubic area; HR 1.3; CI 1.1-1.5) had a worse prognosis than those on easily visible sites (face, chest, abdomen, anterior upper arms and thighs, lower arms and legs, dorsum of hands and feet, palms). In conclusion, highly intermittent UVR exposure sites and poor skin visibility presumably correlate with reduced melanoma survival, independent of established tumor characteristics. A limitation of the study was the lack of information on actual individual UVR exposure.

Doxorubicin enhances the capacity of B cells to activate T cells in urothelial urinary bladder cancer.

Cancer is currently treated by a combination of therapies, including chemotherapy which is believed to suppress the immune system. Combination of immunotherapy and chemotherapy correlates with improved survival but needs careful planning in order to achieve a synergistic effect. In this study, we have demonstrated that doxorubicin treatment of B cells resulted in increased expression of CD86 and concordantly increased CD4+ T cell activation in the presence of superantigen, an effect that was inhibited by the addition of a CD86 blocking antibody. Furthermore, doxorubicin resulted in decreased expression of the anti-inflammatory cytokines IL-10 and TNF-α. Finally, B cells from urinary bladder cancer patients, treated with a neoadjuvant regiment containing doxorubicin, displayed increased CD86-expression. We conclude that doxorubicin induces CD86 expression on B cells and hence enhances their antigen-presenting ability in vitro, a finding verified in patients. Development of tailored time and dose schedules may increase the effectiveness of combining chemotherapy and immunotherapy.

Combined BRAF and MEK inhibition versus BRAF inhibition alone in melanoma.

BACKGROUND: Combined BRAF and MEK inhibition, as compared with BRAF inhibition alone, delays the emergence of resistance and reduces toxic effects in patients who have melanoma with BRAF V600E or V600K mutations. METHODS: In this phase 3 trial, we randomly assigned 423 previously untreated patients who had unresectable stage IIIC or stage IV melanoma with a BRAF V600E or V600K mutation to receive a combination of dabrafenib (150 mg orally twice daily) and trametinib (2 mg orally once daily) or dabrafenib and placebo. The primary end point was progression-free survival. Secondary end points included overall survival, response rate, response duration, and safety. A preplanned interim overall survival analysis was conducted. RESULTS: The median progression-free survival was 9.3 months in the dabrafenib-trametinib group and 8.8 months in the dabrafenib-only group (hazard ratio for progression or death in the dabrafenib-trametinib group, 0.75; 95% confidence interval [CI], 0.57 to 0.99; P=0.03). The overall response rate was 67% in the dabrafenib-trametinib group and 51% in the dabrafenib-only group (P=0.002). At 6 months, the interim overall survival rate was 93% with dabrafenib-trametinib and 85% with dabrafenib alone (hazard ratio for death, 0.63; 95% CI, 0.42 to 0.94; P=0.02). However, a specified efficacy-stopping boundary (two-sided P=0.00028) was not crossed. Rates of adverse events were similar in the two groups, although more dose modifications occurred in the dabrafenib-trametinib group. The rate of cutaneous squamous-cell carcinoma was lower in the dabrafenib-trametinib group than in the dabrafenib-only group (2% vs. 9%), whereas pyrexia occurred in more patients (51% vs. 28%) and was more often severe (grade 3, 6% vs. 2%) in the dabrafenib-trametinib group. CONCLUSIONS: A combination of dabrafenib and trametinib, as compared with dabrafenib alone, improved the rate of progression-free survival in previously untreated patients who had metastatic melanoma with BRAF V600E or V600K mutations.

Presence of immune cells, low tumor proliferation and wild type BRAF mutation status is associated with a favourable clinical outcome in stage III cutaneous melanoma.

BACKGROUND: The variable prognosis in stage III cutaneous melanoma is partially due to unknown prognostic factors. Improved prognostic tools are required to define patients with an increased risk of developing metastatic disease who might benefit from adjuvant therapies. The aim was to examine if cellular immune markers in association with tumor proliferation rate and BRAF mutation status have an impact on prognosis in stage III melanoma. METHODS: We have used two sets of case series with stage III disease: 23 patients with short survival (≤ 13 months) and 19 patients with long survival (≥ 60 months). Lymph node metastases were analyzed for Ki67, CD8 and FOXP3 protein expression using immunohistochemistry. BRAF mutation status was analyzed in a previous study on the same samples. RESULTS: Low tumor proliferation rate was significantly associated with a better prognosis (p = 0.013). Presence of FOXP3+ T cells was not correlated to adverse clinical outcome. A highly significant trend for a longer survival was found in the presence of an increasing number of markers; CD8+ and FOXP3+ T cells, low tumor proliferation and BRAF wildtype status (p = 0.003). Presence of at least three of these four markers was found to be an independent favorable prognostic factor (OR 19.4, 95% CI 1.9-197, p = 0.012), when adjusting for ulceration and number of lymph node metastases. Proliferation alone remained significant in multivariate analyses (OR 26.1, 95% CI 2.0-344, p = 0.013) but with a wider confidence interval. This panel still remained independent when also adjusting for a previously identified prognostic glycolytic-pigment panel. CONCLUSIONS: We have demonstrated that presence of immune cells in association with tumor proliferation and BRAF mutation status may further contribute to identify stage III melanoma patients with high risk of relapse.
