Standardizing Integrated Oncology and Palliative Care Across Service Levels: Challenges in Demonstrating Effects in a Prospective Controlled Intervention Trial.

INTRODUCTION: Patients with cancer often want to spend their final days at home. In Norway, most patients with cancer die in institutions. We hypothesized that full integration of oncology and palliative care services would result in more time spent at home during end-of-life. METHODS: A prospective non-randomized intervention trial was conducted in two rural regions of Mid-Norway. The hospitals' oncology and palliative care outpatient clinics and surrounding communities participated. An intervention including information, education, and a standardized care pathway was developed and implemented. Adult non-curative patients with cancer were eligible. Proportion of last 90 days of life spent at home was the primary outcome. RESULTS: We included 129 patients in the intervention group (I) and 76 patients in the comparison group (C), of whom 82% of patients in I and 78% of patients in C died during follow-up. The mean proportion of last 90 days of life spent at home was 0.62 in I and 0.72 in C (p = 0.044), with 23% and 36% (p = 0.073), respectively, dying at home. A higher proportion died at home in both groups compared to pre-study level (12%). During the observation period the comparison region developed and implemented an alternative intervention to the study intervention, with the former more focused on end-of-life care. CONCLUSION: A higher proportion of patients with cancer died at home in both groups compared to pre-study level. Patients with cancer in I did not spend more time at home during end-of-life compared to those in C. The study intervention focused on the whole disease trajectory, while the alternative intervention was more directed towards end-of-life care. "Simpler" and more focused interventions on end-of-life care may be relevant for future studies on integration of palliative care into oncology. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02170168.

Palliative care is an important part of cancer care to improve patients' quality of life. To be cared for and die in the preferred place are quality markers in palliative care. Patients with cancer often want to spend their final days at home. In Norway, most patients with cancer die in institutions. We hypothesized that full integration of cancer and palliative care would result in more time spent at home during end-of-life. An intervention that included information, education, and a standardized care pathway was developed and implemented in a region of Mid-Norway (the intervention region, I). A similar region served as comparison region (C). Adult patients with cancer treated with non-curative intent were eligible. Altogether, 129 patients in I and 76 patients in C were included in the study, of whom 82% in I and 78% in C died during follow-up. The mean proportion of time spent at home last 90 days of life was 0.62 in I and 0.72 in C (p = 0.044), and 22.6% and 35.6% (p = 0.073) died at home, respectively. A higher proportion died at home in both groups compared to pre-study national levels (12%). During the study period, C developed and implemented an alternative intervention to the study intervention, with the former placing more focus on end-of-life care compared to the she study intervention that focused on the whole disease trajectory. This may explain why the intervention did not result in more time spent at home during end-of-life as compared to C. "Simpler" interventions directed towards the study's primary outcome may be relevant for future studies on integration of palliative care into oncology.

Cancer patients have a reduced likelihood of dying in hospital with advance care planning in primary health care and a summarizing palliative plan: a prospective controlled non-randomized intervention trial.

BACKGROUND: Advance care planning (ACP) allows patients to define their goals and preferences. Spending more time at home and less time in the hospital, along with avoiding death in the hospital, are often considered desirable outcomes of palliative care (PC). In 2015, 36% of cancer patients died in the hospital and 13% died at home in Norway. METHOD: From 2015 to 2022, this prospective controlled non-randomized intervention trial observed 144 cancer patients with or without an organized ACP conversation in primary health care and a summarizing palliative plan (ClinicalTrials.gov Identifier: NCT02170168, 23 June 2014). The patients were identified through contact with the local cancer outpatient clinic or hospital-based PC team. RESULTS: A total of 128 patients died during the observation period. Of these, 67 patients had an organized ACP conversation and summarizing palliative plan (intervention (I) group) and 61 had not (control (C) group). Dying in the hospital was significantly less common for patients in the I group compared to the C group (17.9% vs. 34.4%; X2 (1, n = 128) = 4.55, p = 0.033). There were no differences between the groups in terms of where they spent their time in the last 90 days of life (home, nursing home, or hospital). Most patients (62%) preferred to die at home. The observed differences between the groups regarding preferred and actual places of death did not reach statistical significance. CONCLUSION: With organized ACP conversations in primary health care and a summarizing palliative plan, cancer patients died less often in the hospital in our observational study. A structured ACP approach integrating palliative care for cancer patients into primary health care can support patients´ preferences at the end of life.

Cancer patients spend more time at home and more often die at home with advance care planning conversations in primary health care: a retrospective observational cohort study.

BACKGROUND: Spending time at home and dying at home is advocated to be a desirable outcome in palliative care (PC). In Norway, home deaths among cancer patients are rare compared to other European countries. Advance care planning (ACP) conversations enable patients to define goals and preferences, reflecting a person's wishes and current medical condition. METHOD: The study included 250 cancer patients in the Romsdal region with or without an ACP conversation in primary health care who died between September 2018 and August 2020. The patients were identified through their contact with the local hospital, cancer outpatient clinic or hospital-based PC team. RESULTS: During the last 90 days of life, patients who had an ACP conversation in primary health care (N=125) were mean 9.8 more days at home, 4.5 less days in nursing home and 5.3 less days in hospital. Having an ACP conversation in primary health care, being male or having a lower age significantly predicted more days at home at the end of life (p< .001). Patients with an ACP conversation in primary health care where significantly more likely to die at home (p< .001) with a four times higher probability (RR=4.5). Contact with the hospital-based PC team was not associated with more days at home or death at home. Patients with contact with the hospital-based PC team were more likely to have an ACP conversation in primary health care. CONCLUSION: Palliative cancer patients with an ACP conversation in primary health care spent more days at home and more frequently died at home. Data suggest it is important that ACP conversations are conducted in primary health care setting.

Implementing a Standardized Care Pathway Integrating Oncology, Palliative Care and Community Care in a Rural Region of Mid-Norway.

INTRODUCTION: To improve quality across levels of care, we developed a standardized care pathway (SCP) integrating palliative and oncology services for hospitalized and home-dwelling palliative cancer patients in a rural region. METHODS: A multifaceted implementation strategy was directed towards a combination of target groups. The implementation was conducted on a system level, and implementation-related activities were registered prospectively. Adult patients with advanced cancer treated with non-curative intent were included and interviewed. Healthcare leaders (HCLs) and healthcare professionals (HCPs) involved in the development of the SCP or exposed to the implementation strategy were interviewed. In addition, HCLs and HCPs exposed to the implementation strategy answered standardized questionnaires. Hospital admissions were registered prospectively. RESULTS: To assess the use of the SCP, 129 cancer patients were included. Fifteen patients were interviewed about their experiences with the patient-held record (PHR). Sixty interviews were performed among 1320 HCPs exposed to the implementation strategy. Two hundred and eighty-seven HCPs reported on their training in and use of the SCP. Despite organizational cultural differences, developing an SCP integrating palliative and oncology services across levels of care was feasible. Both HCLs and HCPs reported improved quality of care in the wake of the implementation process. Two and a half years after the implementation was launched, 28% of the HCPs used the SCP and 41% had received training in its use. Patients reported limited use and benefit of the PHR. CONCLUSION: An SCP may be a usable tool for integrating palliative and oncology services across care levels in a rural region. An extensive implementation process resulted in improvements of process outcomes, yet still limited use of the SCP in clinical practice. HCLs and HCPs reported improved quality of cancer care following the implementation process. Future research should address mandatory elements for usefulness and successful implementation of SCPs for palliative cancer patients.

When a patient has incurable cancer, it is beneficial to introduce palliative care early in the disease trajectory along with anti-cancer treatment. A standardized care pathway is a method to improve quality and reduce variation in healthcare. It can promote integrated healthcare services in palliative care, e.g. by specifying action points when the patient's situation is changing. In this study, a standardized care pathway for cancer patients with palliative care needs was developed in a rural region of Norway. The pathway focused on patients' needs and symptoms and on smooth transition between levels of care. An educational program and an information strategy were developed to ensure implementation. To evaluate the implementation, all activity regarding the implementation process was registered. Cancer patients and healthcare professionals were interviewed and answered questionnaires. One thousand three hundred and twenty healthcare professionals were exposed to the implementation strategy. One hundred and twenty-nine cancer patients were followed up according to the standardized care pathway. Despite different perspectives of care, it was feasible to develop a standardized care pathway for palliative cancer patients across care settings. A paper-based patient-held record was only found to be useful by a limited number of patients. An extensive implementation process was completed and resulted in improvements regarding healthcare professionals' experience with the quality of cancer care in the region, but limited use of the care pathway in clinical practice. Further research should identify the most important elements for usefulness and successful implementation of the care pathway.

Spiritual quality of life in family carers of patients with advanced cancer-a cross-sectional study.

PURPOSE: Caring affects carers' psychological and physical health, mortality, and quality of life (QoL) negatively. Lower spiritual QoL is associated with anxiety and depression, but the spiritual dimension is rarely investigated in carers. The present study aimed to explore which patient- and carer-related characteristics were associated with spiritual QoL in carers of patients with advanced cancer. METHODS: Secondary analyses were conducted using data from a prospective study investigating integration between oncology and palliative care. Adult patients with advanced cancer and their carers were included, and baseline data considering demographics, clinical characteristics, symptoms, social support, and religious meaning-making were registered. Spiritual QoL was measured using the Functional Assessment of Chronic Illness Therapy - Spiritual well-being (FACIT-Sp-12) questionnaire. Associations to spiritual QoL were explored by bivariate and multivariate regression models. RESULTS: In total, 84 carers were included, median age was 62.5 years, 52 (62%) were female, and the average spiritual QoL score was 23.3. In bivariate analyses, higher education, social support, and lower patients' symptom burden were significantly associated with higher spiritual QoL. The multivariate regression model (n=77) had an explained variance (R2) = 0.34 and showed a significant association for social support, higher education, having children < 18 years living at home, and patient's age. CONCLUSION: The study indicates that spiritual QoL in carers were low and were negatively affected by several factors related to both carers and patients. However, there could be other important factors not yet described. Health care professionals should be aware of the known associated factors, as carers who hold these may need extra support.

A qualitative study of bereaved family caregivers: feeling of security, facilitators and barriers for rural home care and death for persons with advanced cancer.

BACKGROUND: For cancer patients and their family, an important factor that determines the choice to die at home is the caregivers' feeling of security when caring for the patient at home. Support to caregivers from healthcare professionals is important for the feeling of security. In rural areas, long distances and variable infrastructure may influence on access to healthcare services. This study explored factors that determined the security of caregivers of patients with advanced cancer who cared for the patients at home at the end of life in the rural region of Sogn og Fjordane in Norway, and what factors that facilitated home death. METHODS: A qualitative study using semi-structured in-depth interviews with bereaved with experience from caring for cancer patients at home at the end of life was performed. Meaning units were extracted from the transcribed interviews and divided into categories and subcategories using Kvale and Brinkmann's qualitative method for analysis. RESULTS: Ten bereaved caregivers from nine families where recruited. Five had lived together with the deceased. Three main categories of factors contributing to security emerged from the analysis: "Personal factors", "Healthcare professionals" and "Organization" of healthcare. Healthcare professionals and the organization of healthcare services contributed most to the feeling of security. CONCLUSION: Good competence in palliative care among healthcare professionals caring for patients with advanced cancer at home and well- organized palliative care services with defined responsibilities provided security to caregivers caring for advanced cancer patients at home in Sogn og Fjordane.

Fully Integrated Oncology and Palliative Care Services at a Local Hospital in Mid-Norway: Development and Operation of an Innovative Care Delivery Model.

INTRODUCTION: Early access to cancer palliative care is recommended. Descriptions of structures and processes of outpatient palliative care clinics operated within smaller hospitals are scarce. This paper presents the development and operation of a fully integrated cancer and palliative care outpatient clinic at a local hospital in a rural region of Mid-Norway offering palliative care concurrent with cancer treatment. A standardized care pathway was applied. METHODS: Palliative care is in Norway part of the public healthcare system. Official recommendations recent years point out action points to improve delivery of palliative care. An integrated cancer and palliative care outpatient clinic at a local hospital and an innovative care delivery model was developed and operated in this setting. Patients were recruited for a descriptive study of the patient population. Clinical data were collected by clinical staff and 13 symptom intensities were reported by the patients. RESULTS: Cancer and palliative care were provided by one team of healthcare professionals trained in both fields. There was a close collaboration with the other departments at the hospital, with its affiliated tertiary hospital, and with community health and care services to provide timely referral, enhanced continuity, and improved coordination of care. Eighty-eight patients were included. Mean age was 65.6 years, the most common cancer diagnoses were digestive organs (22.7%), male genital organs (20.5%) or breast (25.0%), 75.0% had metastatic or locally advanced cancer, 59.1% were treated with non-curative intention and 93.1% had Karnofsky Performance Status ≥ 80%. Median scores of individual symptoms ranged from 0 to 3 (numerical rating scale, 0-10) and 61.0% reported at least one clinically significant symptom rating (≥ 4). CONCLUSION: This delivery model of integrated outpatient cancer and palliative care is particularly relevant in rural regions allowing cancer patients access to palliative care earlier in the disease trajectory and closer to home.

Palliative care is an important part of cancer care which aims at improving cancer patients' symptom burden and quality of life and support their carers. Palliative care has traditionally been separated from cancer care. During the last decade, one has become aware of the benefits of introducing palliative care early and concurrent with cancer treatment. Most cancer patients are nowadays treated as outpatients. Availability of palliative care as a routine part of outpatient cancer clinics is therefore important. Most of the described models of early palliative care in cancer care are within large tertiary hospitals. Here it is described how early palliative care was delivered to cancer patients in an outpatient clinic in a smaller hospital in a rural region of Mid-Norway. In this integrated cancer and palliative care outpatient clinic, cancer and palliative care were provided by one team of healthcare professionals trained in both fields. The integrated outpatient clinic collaborated closely with the other hospital departments and with community health and care services. This was needed to be able to offer palliative care to all cancer patients in need of it, and closer to their home. Many of the patients attending the integrated outpatient clinic could not be cured for their cancer. They did not have many symptoms of their cancer, and they had a high functional status. This demonstrated that the integrated outpatient clinic in this local hospital was a relevant place to offer palliative care early and concurrent with cancer treatment before symptoms became severe.

Resilience for family carers of advanced cancer patients-how can health care providers contribute? A qualitative interview study with carers.

BACKGROUND: Caring for advanced cancer patients affects carers' psychological and physical health. Resilience has been defined as "the process of adapting well in the face of adversity, trauma, tragedy, threats or even significant sources of threat." AIM: The aim of this study was to explore factors promoting carer resilience, based on carers' experiences with and preferences for health care provider support. DESIGN: Qualitative, semi-structured, individual interviews with family carers of advanced cancer patients were performed until data saturation. The interviews were recorded, transcribed, and analyzed using systematic text condensation. SETTING/PARTICIPANTS: Carers ( n = 14) of advanced cancer patients, not receiving curative treatment, admitted to an integrated curative and palliative care cancer outpatient clinic or to a university hospital cancer clinic, were included. RESULTS: 14 carers of advanced cancer patients were included; 7 men, 7 women, and mean age of 59 years; 3 were bereaved; 12 were partners; 5 had young and teenage children. Four main resilience factors were identified: (1) being seen and known by health care providers-a personal relation; (2) availability of palliative care; (3) information and communication about illness, prognosis, and death; and (4) facilitating a good carer-patient relation. CONCLUSION: Health care providers may enhance carers' resilience by a series of simple interventions. Education should address carers' support needs and resilience. Systematic assessment of carers' support needs is recommended. Further investigation is needed into how health care providers can help carers and patients communicate about death.

FGFR3 is expressed and is important for survival in INA-6, a human myeloma cell line without a t(4;14).

OBJECTIVES: Fibroblast growth factor receptor 3 (FGFR3) is a proto-oncogene that is often dysregulated together with multiple myeloma SET-domain (MMSET) by the immunoglobulin heavy chain (IGH) gene in t(4;14)(pos) multiple myeloma (MM) cells, and which is usually not expressed in MM cells without this translocation. Whether FGFR3 may play a role in MM cells without t(4;14) and the IGH-MMSET fusion protein is unclear and is the focus of this report. METHODS: FGFR3 expression was explored in cell lines with and without t(4;14) by fluorescence in situ hybridization (FISH), RT-PCR and Western Blot. FGFR3 inhibitors SU5402 and PD173074 were used to explore the role of FGFR3 in these cells. RESULTS: We discovered an amplification of the FGFR3 locus in INA-6, a human MM cell line. We also demonstrated expression of FGFR3 mRNA and protein in the cells, probably caused by the extra copy of the gene. INA-6 cells did not have t(4;14) and neither was there any involvement of the other IG loci in translocations with the FGFR3 gene. The FGFR3 inhibitors decreased the proliferation of INA-6. CONCLUSION: The decreased viability and proliferation in INA-6, following inhibition with FGFR3 inhibitors, indicates that FGFR3 may play a role also in cells without t(4;14) - and hence without high expression of MMSET, the ubiquitous oncoprotein in MM cells with t(4;14). This gives further credibility to the notion that FGFR3 expression is not just an epiphenomenon in t(4;14) MM, but an important part of the malignant phenotype.

High expression of BCL3 in human myeloma cells is associated with increased proliferation and inferior prognosis.

BACKGROUND: BCL3 is a putative oncogene encoding for a protein belonging to the inhibitory kappaB-family. We experienced that this putative oncogene was a common target gene for growth-promoting cytokines in myeloma cell lines. METHODS: Gene expression of BCL3 was studied in 351 newly diagnosed myeloma patients, 12 patients with smouldering myeloma, 44 patients with monoclonal gammopathy of undetermined significance and 22 healthy individuals. Smaller material of samples was included for mRNA detection by RT-PCR, protein detection by Western blot and immunohistochemistry, and for cytogenetic studies. A total of eight different myeloma cell lines were studied. RESULTS: Bcl-3 was induced in myeloma cell lines by interleukin (IL)-6, IL-21, IL-15, tumor necrosis factor-alpha and IGF-1, and its upregulation was associated with increased proliferation of the cells. In a population of 351 patients, expression levels of BCL3 above 75th percentile were associated with shorter 5-yr survival. When this patient population was divided into subgroups based on molecular classification, BCL3 was significantly increased in a poor risk subgroup characterized by overexpression of cell cycle and proliferation related genes. Intracellular localization of Bcl-3 was dependent on type of stimulus given to the cell. CONCLUSION: BCL3 is a common target gene for several growth-promoting cytokines in myeloma cells and high expression of BCL3 at the time of diagnosis is associated with poor prognosis of patients with multiple myeloma (MM). These data may indicate a potential oncogenic role for Bcl-3 in MM.

A low serum level of soluble tumor necrosis factor receptor p55 predicts response to thalidomide in advanced multiple myeloma.

BACKGROUND AND OBJECTIVES: Thalidomide modulates the production of tumor necrosis factor (TNF-alpha). Soluble TNF receptors, TNFR p55 and TNFR p75, modify TNF-alpha activity. In this study, we explored the relation between soluble TNF receptors and outcome in patients with advanced multiple myeloma treated with thalidomide. DESIGN AND METHODS: The levels of soluble TNF receptor p55 and p75 were assessed in serum from 34 myeloma patients with relapsed or refractory disease before starting thalidomide treatment. Serial measurements were performed for 16 patients in serum collected during treatment. RESULTS: The pre-treatment serum level of soluble TNFR p55 in thalidomide responders was significantly lower than that in non-responders (median 1.75 ng/mL (range 1.19-2.84) vs. 2.79 ng/mL (1.36-5.51), p=0.004). The levels of p55 declined significantly during treatment. The levels of p75 showed the same pattern as p55, but the differences were not significant. The median survival of myeloma patients with pre-treatment levels of p55 < 2.79 ng/mL was 404 days; the median survival of patients with pre-treatment levels >or= 2.79 ng/mL was shorter (65 days, log-rank test p=0.02). INTERPRETATION AND CONCLUSIONS: We conclude that soluble TNFR p55 is an adverse prognostic factor in myeloma patients with relapsed or refractory disease treated with thalidomide. Patients with a low pre-treatment level of this receptor have a better response rate and a longer overall survival.

Osteopontin is an adhesive factor for myeloma cells and is found in increased levels in plasma from patients with multiple myeloma.

BACKGROUND AND OBJECTIVES: Osteopontin (OPN) is a non-collagenous matrix protein produced by various cells including osteoblasts, osteoclasts and several types of tumor cells. It is involved in a number of physiologic and pathologic events including adhesion, angiogenesis, apoptosis, inflammation, wound healing and tumor metastasis. We wanted to investigate the potential role of OPN in multiple myeloma. DESIGN AND METHODS: Myeloma cells and stromal cells from myeloma patients were investigated as potential OPN-producers. Furthermore, OPN was tested in proliferation, migration and adhesion assays with myeloma cells. Serum and plasma OPN in myeloma patients were measured by enzyme-linked immunosorbent assay (ELISA). OPN levels were correlated to disease variables at diagnosis and to disease outcome. RESULTS: Myeloma cells produce OPN, and stromal cells from myeloma patients express higher levels of OPN than stromal cells from healthy controls. The myeloma cell lines ANBL-6 and INA-6 adhered to OPN. NOD/SCID mice inoculated with OPN-producing ANBL-6 cells had elevated levels of murine OPN in serum, whereas human OPN was not detectable. Plasma and serum levels of OPN were significantly higher in myeloma patients than in healthy individuals. Interpretation and Conclusions. Myeloma cell lines adhere to OPN, indicating that elevated stromal expression of OPN may be one of the factors responsible for the retention of myeloma cells in the bone marrow. The elevated plasma OPN levels in myeloma patients could be due to both production of OPN by the tumor cells and tumor-induced production of OPN by non-tumor cells.

Bone morphogenetic protein-5, -6 and -7 inhibit growth and induce apoptosis in human myeloma cells.

Previously, bone morphogenetic protein (BMP)-2 and -4 have been shown to inhibit proliferation and induce apoptosis in human myeloma cells. BMP-2 and -4 belong to a subgroup of BMPs using the BMP receptors Alk-3 or -6. In this study, we examined the effects on human myeloma cells of BMP-6 and -7, members of a different BMP subgroup, which mainly utilize Alk-2 as their receptor. All cell lines examined expressed mRNA for the BMP-6 and -7 receptor Alk-2. We did not detect transcripts for the BMP-2 and -4 receptors Alk-3 or Alk-6 in INA-6 and RPMI-8226 cells by RT-PCR. Accordingly, the intracellular signalling molecules Smad-1, -5 and -8 were not phosphorylated by BMP-4 in INA-6 and RPMI-8226 cells. The expression patterns of various BMP receptors in the myeloma cell lines explained the differences in responses to the various BMPs. Alk-2-expressing cell lines responded with growth inhibition and apoptosis to BMP-6 and -7, whereas cell lines lacking both Alk-3 and -6 were resistant to BMP-4. Soluble Alk-3 and -6 were able to neutralize the BMP-4 effects in BMP-4-responsive cell lines. All BMPs reduced viability in more than 70% of purified primary myeloma cell samples. BMPs have intriguing antitumor effects in vitro. Importantly, myeloma cells not responsive to BMP-2 and -4 may still be sensitive to BMP-6 or -7. It is possible that therapeutic use of BMP or BMP analogues could have an impact on both myeloma bone disease and myeloma cell growth.

Interleukin-21 is a growth and survival factor for human myeloma cells.

Interleukin-21 (IL-21) is a recently cloned cytokine with homology to IL-2, IL-4, and IL-15. In this study we examined the effects of IL-21 on human myeloma cells. We found that IL-21 induced proliferation and inhibited apoptosis of the IL-6-dependent human myeloma cell lines ANBL-6, IH-1, and OH-2. The potency of IL-21 was close to that of IL-6 in the OH-2 cell line. Neutralizing antibodies to IL-6 or the IL-6 receptor transducer chain (gp130) did not affect IL-21-induced DNA synthesis, indicating that IL-21-induced proliferation was not mediated through these proteins. Tumor necrosis factor (TNF), another stimulator of myeloma cell growth, up-regulated the expression level of IL-21 receptor (IL-21R), and combinations of TNF and IL-21 gave synergistic effects on myeloma cell proliferation. Furthermore, 4 of 9 purified samples of primary myeloma cells showed a significant increase in DNA synthesis on stimulation of the cells by IL-21. By Western blot analysis, we demonstrated that the intracellular signaling pathways of IL-21 in myeloma cells involved phosphorylation of Jak1, Stat3, and Erk1/2 (p44/42 mitogen-activated protein kinase). IL-21 is a novel growth and survival factor in multiple myeloma and may represent a target for future therapy.
