Specialist palliative care until the very end of life - reports of family caregivers and the multiprofessional team

BACKGROUND

Specialist palliative care (SPC) includes care for incurably ill patients and their family caregivers at home or on a palliative care ward until the very end of life. However, in the last days of life, patients can rarely express their needs and little is known about SPC outcomes as reported by multiprofessional SPC teams and family caregivers.

METHODS

Using the Palliative Care Outcome Scale (POS; Score 0-40), proxy assessments of SPC outcomes in the patient's last 3 days of life were performed by SPC teams and primary family caregivers of three home care and three inpatient services. Additional questions were asked about problems solved 'particularly well' or 'inadequately' (last 7 days), which were content analyzed and quantified.

RESULTS

Proxy assessments by SPC teams were available in 142 patients (of whom 51% had died at home). Family caregiver assessments exist for a subgroup of 60 of these patients. SPC teams (POS total score: mean 13.8, SD 6.3) reported SPC outcomes slightly better than family caregivers (mean 16.7, SD 6.8). The POS items consistently rated as least affected (= 0) by both, SPC teams and family caregivers, were 'not wasted time' (team 99%/family caregivers 87%), 'information' (84%/47%) and 'support' (53%/31%). Items rated as most affected (= 4) were 'patient anxiety' (31%/51%), 'life not worthwhile' (26%/35%) and 'no self-worth' (19%/30%). Both groups indicated more problems solved 'particularly well' than 'inadequately'; the latter concerned mainly clinically well-known challenges during end-of-life care and family caregiver care.

CONCLUSIONS

This study shows the range and type of symptoms and other concerns reported in the patient's last days. Starting points for further improvements in family caregiver care and psychosocial and spiritual issues were identified.

What are the personal last wishes of people with a life-limiting illness? Findings from a longitudinal observational study in specialist palliative care

Background

Personal last wishes of people facing a life-limiting illness may change closer to death and may vary across different forms of specialist palliative care (SPC).

Aims

To explore the presence and common themes of last wishes over time and according to the SPC settings (inpatient vs. home-based SPC), and to identify factors associated to having a last wish.

Methods

Patients enrolled in a longitudinal study completed questionnaires at the onset (baseline, t₀) and within the first 6 weeks (follow-up, t₁) of SPC including an open-ended question on their personal last wishes. Last wishes were content analyzed, and all  wishes were coded for presence or absence of each of the identified themes. Changes of last wishes (t₀-t₁) were analyzed by a McNemar test. The chi-square-test was used to compare the two SPC settings. Predictors for the presence of a last wish were identified by logistic regression analysis.

Results

Three hundred sixty-one patients (mean age, 69.5 years; 49% female) answered at t₀, and 130 at t₁. In cross-sectional analyses, the presence of last wishes was higher at t₀ (67%) than at t₁ (59%). Comparisons revealed a higher presence of last wishes among inpatients than those in home-based SPC at t₀ (78% vs. 62%; p = .002), but not at t₁. Inpatient SPC (OR = 1.987, p = .011) and greater physical symptom burden over the past week (OR = 1.168, p < .001) predicted presence of a last wish at t₀. Common themes of last wishes were Travel, Activities, Regaining health, Quality of life, Being with family and friends, Dying comfortably, Turn back time, and Taking care of final matters. The most frequent theme was Travel, at both t₀ (31%) and t₁ (39%). Themes did not differ between SPC settings, neither at t₀ nor at t₁. Longitudinal analyses (t₀-t₁) showed no significant intra-personal changes in the presence or any themes of last wishes over time.

Conclusions

In this late phase of their illness, many patients voiced last wishes. Our study suggests working with such wishes as a framework for person-centered care. Comparisons of SPC settings indicate that individualized approaches to patients’ last wishes, rather than setting-specific approaches, may be important.

Need for additional professional psychosocial and spiritual support in patients with advanced diseases in the course of specialist palliative care - a longitudinal observational study

BACKGROUND

We investigated the need for additional professional support and associated factors in patients (pts) at initiation and in the course of in- and outpatient specialist palliative care (I-SPC/O-SPC).

METHODS

Pts entering an urban SPC network consecutively completed questionnaires on psychosocial/spiritual problems and support needs within 72 h (T0) as well as within the first 6 weeks (T1) of SPC. Hierarchical linear regression analysis was used to investigate the impact of sociodemographic / disease-related variables, psychological / physical burden, social support, and SPC setting on the extent of support needs.

RESULTS

Four hundred twenty-five pts (70 years, 48% female, 91% cancer, 67% O-SPC) answered at T0, and 167 at T1. At T0, main problems related to transportation, usual activities, and dependency (83-89%). At T1, most prevalent problems also related to transportation and usual activities and additionally to light housework (82-86%). At T0, support needs were highest for transportation, light housework, and usual activities (35-41%). Cross-sectional comparisons of SPC settings revealed higher problem scores in O-SPC compared to I-SPC at T0 (p = .039), but not at T1. Support need scores were higher in O-SPC at T0 (p < .001), but lower at T1 (p = .039). Longitudinal analyses showed a decrease of support need scores over time, independent from the SPC setting. At T0, higher distress (p = .047), anxiety/depression (p < .001), physical symptom burden (p < .001) and I-SPC (p < .001) were associated with higher support need scores (at T1: only higher distress, p = .037).

CONCLUSION

Need for additional professional psychosocial/spiritual support was identified in up to 40% of pts. with higher need at the beginning of O-SPC than of I-SPC. During SPC, this need decreased in both settings, but got lower in O-SPC than in I-SPC over time. Support need scores were not only associated with psychological, but also physical burden.

Kidney Dysfunction Is Associated with Thrombosis and Disease Severity in Myeloproliferative Neoplasms: Implications from the German Study Group for MPN Bioregistry

Simple Summary

In patients with myeloproliferative neoplasms (MPN) and in patients with kidney dysfunction, a higher rate of thrombosis has been reported compared with the general population. Furthermore, MPN patients are more prone to develop kidney dysfunction. In our study, we assessed the importance of specific risk factors for kidney dysfunction and thrombosis in MPN patients. We found that the rate of thrombosis is correlated with the degree of kidney dysfunction, especially in myelofibrosis. Significant associations for kidney dysfunction included arterial hypertension, MPN treatment, and increased inflammation, and those for thrombosis comprised arterial hypertension, non-excessive platelet counts, and antithrombotic therapy. The identified risk factor associations varied between MPN subtypes. Our data suggest that kidney dysfunction in MPN patients is associated with an increased risk of thrombosis, mandating closer monitoring, and, possibly, early thromboprophylaxis.

Abstract

Inflammation-induced thrombosis represents a severe complication in patients with myeloproliferative neoplasms (MPN) and in those with kidney dysfunction. Overlapping disease-specific attributes suggest common mechanisms involved in MPN pathogenesis, kidney dysfunction, and thrombosis. Data from 1420 patients with essential thrombocythemia (ET, 33.7%), polycythemia vera (PV, 38.5%), and myelofibrosis (MF, 27.9%) were extracted from the bioregistry of the German Study Group for MPN. The total cohort was subdivided according to the calculated estimated glomerular filtration rate (eGFR, (mL/min/1.73 m²)) into eGFR1 (≥90, 21%), eGFR2 (60–89, 56%), and eGFR3 (<60, 22%). A total of 29% of the patients had a history of thrombosis. A higher rate of thrombosis and longer MPN duration was observed in eGFR3 than in eGFR2 and eGFR1. Kidney dysfunction occurred earlier in ET than in PV or MF. Multiple logistic regression analysis identified arterial hypertension, MPN treatment, increased uric acid, and lactate dehydrogenase levels as risk factors for kidney dysfunction in MPN patients. Risk factors for thrombosis included arterial hypertension, non-excessive platelet counts, and antithrombotic therapy. The risk factors for kidney dysfunction and thrombosis varied between MPN subtypes. Physicians should be aware of the increased risk for kidney disease in MPN patients, which warrants closer monitoring and, possibly, early thromboprophylaxis.

Multi-omic based molecular profiling of advanced cancer identifies treatable targets and improves survival in individual patients

A proof-of-concept study was conducted to assess whether patients with advanced stage IV cancer for whom predominantly no standard therapy was available could benefit from comprehensive molecular profiling of their tumor tissue to provide targeted therapy. Tumor samples of 83 patients were collected under highly standardized conditions and analyzed using immunohistochemistry, next-generation sequencing and phosphoprotein profiling. Expression and phosphorylation of key oncogenic pathways were measured to identify targets at the (phospho-) proteomic level. At genomic level, 50 oncogenes and tumor suppressor genes were analyzed. Based on molecular profiling, targeted therapies were decided by the attending oncologist. Accordingly, 28 patients who met the defined criteria fell in two equal-sized groups. One group received targeted therapies while the other did not. Following six months of treatment, disease control was achieved by 49% of patients receiving targeted therapy (complete remission, 14%; partial remission, 21%; stable disease, 14%; disease progression, 36%; death, 14%) and 21% of patients receiving non-targeted therapy (stable disease, 21%; disease progression, 64%; death, 14%). Individual patients experienced dramatic responses to a therapy which otherwise would not have been applied. This approach clarifies the value of multi-omic molecular profiling for cancer diagnostics.

Palliative home care for patients with advanced haematological malignancies-a multicenter survey

Patients with advanced haematological malignancies in non-curative settings suffer from complex physical symptoms and psychosocial distress, comparable to patients with solid tumour entities. Nevertheless, numerous problems at the interface between haematology and palliative home care have been described. From January 2011 until October 2014, we performed a retrospective, multicenter analysis of all patients with haematological malignancies (ICD 10: C81-C95) being treated by the respective specialized palliative home care (SAPV) team. Three SAPV teams were surveyed. Disease entity, physical symptoms, psychosocial distress, number of hospital admissions, therapeutic interventions and other items were analysed descriptively. Of 3,955 SAPV patients, 1.8% (n = 73) suffered from haematological malignancies. Main problems were deterioration of general condition, pain or psychological problems. Thirty-seven percent developed new symptoms during SAPV, mainly pain, psychological distress or deterioration of general status. In 33%, patients were referred to hospital, mainly due to deterioration of general condition or pain. Seventy percent died within 3 months after beginning SAPV care; 83% died at home or in a nursing home. Patients suffering from advanced haematological malignancies were statistically underrepresented in SAPV, and SAPV was installed rather at the very last days of life. By far, more patients were able to die outside a hospital as compared to reference cohorts of haematological patients not being treated in SAPV. The spectrum of documented problems is comparable to other patient cohorts being treated in SAPV; therefore, the options and benefits of palliative home care should be incorporated in palliative haematological treatment concepts more vigorously and consequently.

Bleeding, thrombosis, and anticoagulation in myeloproliferative neoplasms (MPN): analysis from the German SAL-MPN-registry

BACKGROUND

Patients with Ph-negative myeloproliferative neoplasms (MPN), such as polycythemia vera (PV), essential thrombocythemia (ET), and primary myelofibrosis (PMF), are at increased risk for thrombosis/thromboembolism and major bleeding. Due to the morbidity and mortality of these events, antiplatelet and/or anticoagulant agents are commonly employed as primary and/or secondary prophylaxis. On the other hand, disease-related bleeding complications (i.e., from esophageal varices) are common in patients with MPN. This analysis was performed to define the frequency of such events, identify risk factors, and assess antiplatelet/anticoagulant therapy in a cohort of patients with MPN.

METHODS

The MPN registry of the Study Alliance Leukemia is a non-interventional prospective study including adult patients with an MPN according to WHO criteria (2008). For statistical analysis, descriptive methods and tests for significant differences as well as contingency tables were used to identify the odds of potential risk factors for vascular events.

RESULTS

MPN subgroups significantly differed in sex distribution, age at diagnosis, blood counts, LDH levels, JAK2V617F positivity, and spleen size (length). While most thromboembolic events occurred around the time of MPN diagnosis, one third of these events occurred after that date. Splanchnic vein thrombosis was most frequent in post-PV-MF and MPN-U patients. The chance of developing a thromboembolic event was significantly elevated if patients suffered from post-PV-MF (OR 3.43; 95% CI = 1.39-8.48) and splenomegaly (OR 1.76; 95% CI = 1.15-2.71). Significant odds for major bleeding were previous thromboembolic events (OR = 2.71; 95% CI = 1.36-5.40), splenomegaly (OR = 2.22; 95% CI 1.01-4.89), and the administration of heparin (OR = 5.64; 95% CI = 1.84-17.34). Major bleeding episodes were significantly less frequent in ET patients compared to other MPN subgroups.

CONCLUSIONS

Together, this report on an unselected "real-world" cohort of German MPN patients reveals important data on the prevalence, diagnosis, and treatment of thromboembolic and major bleeding complications of MPN.

Factor V Leiden mutation triggering four major complications to standard dose cisplatin-chemotherapy for testicular seminoma: a case report

Background

Major life-threatening complications secondary to cisplatin-based chemotherapy are rare in patients with testicular germ cell tumour (GCT). The incidence of complications increases with dosage of chemotherapy and with a variety of patient-related as well as disease-related conditions. We here report the first case of GCT experiencing as many as four major complications most of which can be explained by the conjunction of several predispositions.

Case presentation

A 48 year old patient with testicular seminoma and bulky retroperitoneal and mediastinal metastases underwent cisplatin based chemotherapy. During the third cycle of chemotherapy, he developed thrombosis of the central venous port device, subtotal splenic infarction, and Bleomycin induced pneumonitis (BIP). Three months after completion of therapy, he was struck by thalamic infarction. Genetic testing then revealed heterozygote mutation of Factor V Leiden (FVL). He received full-dose warfarin anticoagulation treatment and steroid treatment for BIP. 18 months thereafter, the patient is still disease-free, oncologically. Neurological symptoms have disappeared, but pulmonary dysfunction persists with a vital capacity of 50%.

Conclusion

The unique co-incidence of four major complications occurring in this patient were obviously triggered by the genetically determined predisposition of the patient to thrombotic events (FVL). Additionally, several patient-related and disease-related conditions contributed to the unique pattern of complications, i.e. (1) the slightly advanced age (48 years), (2) the prothrombotic condition caused by the disease of cancer, (3) the central venous port device, (4) retroperitoneal bulky metastasis, and (5) cisplatin chemotherapy. Whether or not FVL contributed to the pulmonary fibrosis as well, remains elusive. Practically, in the case of one major vascular complication during cisplatin chemotherapy at standard dose, genetic testing for hereditary thrombophilia should be considered. Thus, precautions for preventing further complications could be initiated.

Abstract P2-16-03: Mature results on metastatic breast cancer patients with prolonged (≥1 year) exposure to first-line bevacizumab combined with paclitaxel from a large observation study

Background: Bevacizumab (BEV) combined with chemotherapy (CT) significantly improves progression-free survival (PFS) and response rate (RR) vs CT alone in the 1st-line treatment of HER2-negative metastatic breast cancer (mBC). BEV was continued for ≥1 year in 20% of patients (pts) in the global ATHENA safety study. We examined a similar subgroup of pts with long-term antibody treatment in a large German observation study. Meanwhile, long-term follow-up of up to 4.5 years allows to present the final results, including mature data on overall survival.

Methods: Pts who had received no prior CT for their mBC received BEV-PAC per the European label. Efficacy and safety were documented in detail for up to 1 year (or until progression, death, or BEV discontinuation if earlier), with subsequent retrieval of long-term follow-up.

Results: By April 2013, final data were available for 865 pts, of whom 167 (20%) were recorded to have received BEV for ≥1 year. Baseline characteristics of this subset relative to the overall population are summarized in the table.

CharacteristicOverall population (n = 865)Subgroup treated with BEV for ≥1 year (n = 167)Median age, years (range)58(26-87)57(28-79)Age ≥65 years,%3230Metastatic at diagnosis,%2018Disease-free inreval &lt;12 months,%24*14#Liver metastasis,%4235≥3 metastatic sites,%3329Triple-negative disease,%1812ECOG performance status &gt;1,%98Prior (neo)adjuvant chemotherapy,%6661*n = 591, initially M0. #n = 113

Dose reductions of long-term BEV occurred in only 3% of cycles and (at least once) in 17% of pts. In the majority of pts treated for ≥1 year, BEV was continued as a single agent after discontinuation of CT. The overall best RR in pts treated for ≥1 year was 80% (complete response in 19%). Median PFS, based on observed events in 83% of all pts, was 18.4 months compared to 9.6 months in the overall population. Overall survival data, based on 524 deaths (61%), show a median of 21.6 months. In the subgroup with prolonged therapy, median OS amounts to 35.7 months with 40% of pts still alive after 4 years. Safety of long-term BEV is as previously reported with only a slightly increased hypertension rate (35%, grade ≥3: 11%), and no cases of gastrointestinal perforation, arterial thromboembolic event, or reversible posterior leukoencephalopathy syndrome.

Conclusions: According to the mature data of this study, including those on OS, a notable proportion of pts appear to derive benefit from prolonged exposure to first-line BEV-containing therapy. Although baseline characteristics exhibited only moderate indicators for an a priori more favorable prognostic profile in the subset of pts treated for ≥1 year, of course one has to keep in mind, that time-related efficacy data are biased towards improved outcome in those able to continue BEV for ≥1 year. However, the median survival of almost 3 years suggests that in a considerable number of pts continued first-line BEV-PAC correlates to favorable outcomes with limited adverse effects.

Pharmacokinetics, pharmacodynamics, safety and tolerability of APG101, a CD95-Fc fusion protein, in healthy volunteers and two glioma patients

APG101 is a glycosylated fusion protein consisting of the extracellular domain of human CD95 (APO-1/Fas) and the Fc domain of human IgG1. Administration of APG101 blocks the interaction between CD95 and its cognate ligand CD95L, thereby inhibiting various pathways involved in e.g. proliferation, migration, differentiation and apoptosis induction. The safety and tolerability of ascending single doses of intravenously applied APG101 was examined in a randomized, double-blind, placebo-controlled, mono-centre "first in man" dose escalation study in 34 healthy male volunteers. Pharmacokinetics and pharmacodynamics were also assessed. The maximum serum concentration of 460 μg/ml was achieved following 1h infusion of the highest dose of 20 mg/kg. The systemic clearance was low (0.4 to 0.5 ml/hkg). Mean terminal elimination half-life was 12 to 15 days. Two patients suffering from malignant glioma received APG101 intravenously under compassionate use conditions. They received doses ranging from 5mg to 600 mg APG101. No adverse events and no clinical significant changes in laboratory parameters related to APG101 were reported. The presence of anti-drug-antibodies (ADA) was investigated and revealed no detectable levels of ADA. Overall, single ascending doses of APG101 up to 20 mg/kgbody weight (bw) administered as infusion over 1h were considered as safe and well tolerated in healthy volunteers. After the application of multiple doses of 400 mg in two glioma patients, steady state for APG101 seemed to be reached. These results support further clinical evaluation of APG101 at a dose of 400 mg per week in glioblastoma patients.

P1-14-04: Prolonged (≥1 Year) Exposure to First-Line Bevacizumab Combined with Paclitaxel in Patients with HER2−Negative Metastatic Breast Cancer Treated in a Routine Oncology Practice Study

Background: First-line bevacizumab (BEV) combined with weekly paclitaxel (PAC) significantly improves progression-free survival (PFS) and response rate (RR) vs PAC alone in HER2−negative metastatic breast cancer (mBC), as shown in E2100. The benefit of BEV combined with other chemotherapy (CT) agents was demonstrated in AVADO and RIBBON-1. BEV was continued for ≥1 year in 21% of patients in the global ATHENA safety study and in 42% of patients in the JO19901 single-arm Japanese study of BEV-PAC. We analyzed data from the subgroup of patients treated for ≥1 year in a German routine oncology practice study to provide insight into the safety and efficacy of prolonged first-line BEV-PAC.

Methods: Patients who had received no prior CT for their mBC received BEV-PAC per the European label. Efficacy and safety were documented for up to 1 year (or until progression, death, or BEV discontinuation if earlier) with additional long-term follow-up. Data from patients treated with BEV for ≥1 year were extracted for this analysis.

Results: By Jan 2011, data were available for 818 patients, of whom 157 (19%) had already received BEV for ≥1 year. Baseline characteristics of this subset relative to the overall population are summarized in the table.

Abstract P2-16-12: First-Line Bevacizumab Combined with Paclitaxel in Triple-Negative Locally Recurrent/Metastatic Breast Cancer: Subpopulation Analysis of 115 Patients Treated in Routine Oncology Practice in Germany

Background: Both progression-free survival (PFS) and response rate (RR) are significantly improved when bevacizumab (Bev) is combined with first-line chemotherapy for locally recurrent/metastatic breast cancer (LR/mBC), as demonstrated in three randomized, phase III trials (E2100, AVADO, RIBBON-1). The benefit derived from Bev appears to be similar in triple-negative (TN) and non-TN LR/mBC according to subanalyses of the randomized trials. We conducted a subpopulation analysis of TN patients treated with first-line Bev-paclitaxel (Pac) in a large German observational study in the context of routine oncology practice. Methods: Patients with HER2-negative LR/mBC received first-line Bev-Pac according to the European label at the time of study design. Safety and efficacy data were collected for up to 1 year (or until progression, death, or Bev discontinuation if earlier). The endpoints were safety and efficacy (PFS and RR). We conducted an exploratory analysis of the subset of patients with TN disease.

Results: Of the 567 patients for whom data are currently available, 115 (20%) had TN disease. Baseline characteristics and efficacy are summarized below. Overall survival data are immature and follow-up is continuing.

Conclusions: In this ongoing study, first-line Bev-Pac demonstrated a 51% RR and median PFS of 7.7 months in patients with TN LR/mBC. These data are consistent with findings from retrospective analyses of randomized phase III trials and a subpopulation analysis of the ATHENA study. Prospective trials evaluating Bev combination regimens in TN breast cancer are ongoing.
