Trends and outcomes of early and late palliative care consultation for adult patients with glioblastoma: A SEER-Medicare retrospective study

Contemporary Patterns of End-of-Life Care Among Medicare Beneficiaries With Advanced Cancer

Importance

Considerable efforts have been dedicated to improving the quality of end-of-life care among patients with advanced cancer in the past decade. Whether the quality has shifted in response to these efforts remains unknown.

Objective

To examine contemporary patterns of end-of-life care among patients with advanced cancer.

Design, Setting, and Participants

This retrospective cohort study used a recent linkage of Surveillance, Epidemiology, and End Results and Medicare data to characterize patterns of end-of-life care. The cohort included fee-for-service Medicare decedents aged 66 years or older who were originally diagnosed with distant-stage breast, prostate, pancreatic, or lung cancers and died between 2014 and 2019. Analyses were conducted between June 1, 2023, and July 31, 2024.

Main Outcomes and Measures

Outcomes included monthly use of acute care, systemic therapy, and supportive care (ie, palliative and hospice care and advanced care planning) in the last 6 months of life. Additionally, a claims-based indicator was evaluated of potentially aggressive care in the last 30 days of life, defined as experiencing more than 1 acute care visit, in-hospital mortality, late receipt of systemic therapy, or hospice entry.

Results

The study included 33 744 Medicare decedents with advanced cancer (mean [SD] age, 75.7 [6.9] years; 52.1% male). From 6 months before death to month of death, there was an increase in the mean (SE) number of acute care visits (from 14.0 [0.5] to 46.2 [0.5] per 100 person-months), hospice use (from 6.6 [0.4] to 73.5 [0.5] per 100 person-months), palliative care (from 2.6 [0.2] to 26.1 [0.6] per 100 person-months), and advanced care planning (from 1.7 [0.6] to 12.8 [1.1] per 100 person-months). Overall, 45.0% of decedents experienced any indicator of potentially aggressive care.

Conclusions and Relevance

This study found persistent patterns of potentially aggressive care, but low uptake of supportive care, among Medicare decedents with advanced cancer. A multifaceted approach targeting patient-, physician-, and system-level factors associated with potentially aggressive care is imperative for improving quality of care at the end of life.

Integrated early palliative care for patients with newly diagnosed glioblastoma: The GLIOSUPPORT feasibility study

Background

Early palliative care improves the quality of life (QoL) and survival in patients with cancer; however, its effects in patients with glioblastoma remain unclear. The GLIOSUPPORT study assessed the feasibility (adherence; primary objective) of an early palliative care program integrated into the standard glioblastoma care pathway. Secondary objectives included the description of the patients' characteristics, QoL, and neuropsychological changes over time, end-of-life decisions, end-of-life treatments, and family carers' perceptions/experiences.

Methods

This interventional, prospective, longitudinal, feasibility study was conducted in a French comprehensive cancer center. Thirty-five patients with newly diagnosed glioblastoma were required to reach an adherence rate of 60%. Adherence was defined as going to 3 palliative care visits scheduled every 12 weeks. Baseline characteristics were compared in patients who did and did not adhere to the palliative care program. Minimal clinically important differences and cut-offs were used to quantify QoL changes.

Results

The adherence rate was 60% (95% CI [42.1%-76.1%]), indicating that the program was feasible. Visual disturbances, communication/initiation deficits, and anxiety were more frequent in the group that did not adhere to the program. Emotional and social functioning, pain, appetite loss, constipation, and headache increased over time (clinically significant differences), whereas neuropsychological disturbances did not change. Half of the participants identified a family proxy and 8.6% wrote advance directives. One month before death, 28.6% of patients were receiving cancer treatment.

Conclusions

Integrating early palliative care in glioblastoma management is feasible. The potential benefits on QoL, mood, and survival must now be evaluated in a larger randomized controlled trial.

Benchmarking palliative care practices in neurooncology: a german perspective

PURPOSE

To benchmark palliative care practices in neurooncology centers across Germany, evaluating the variability in palliative care integration, timing, and involvement in tumor board discussions. This study aims to identify gaps in care and contribute to the discourse on optimal palliative care strategies.

METHODS

A survey targeting both German Cancer Society-certified and non-certified university neurooncology centers was conducted to explore palliative care frameworks and practices for neurooncological patients. The survey included questions on palliative care department availability, involvement in tumor boards, timing of palliative care integration, and use of standardized screening tools for assessing palliative burden and psycho-oncological distress.

RESULTS

Of 57 centers contacted, 46 responded (81% response rate). Results indicate a dedicated palliative care department in 76.1% of centers, with palliative specialists participating in tumor board discussions at 34.8% of centers. Variability was noted in the initiation of palliative care, with early integration at the diagnosis stage in only 30.4% of centers. The survey highlighted a significant lack of standardized spiritual care assessments and minimal use of advanced care planning. Discrepancies were observed in the documentation and treatment of palliative care symptoms and social complaints, underscoring the need for comprehensive care approaches.

CONCLUSION

The study highlights a diverse landscape of palliative care provision within German neurooncology centers, underscoring the need for more standardized practices and early integration of palliative care. It suggests the necessity for standardized protocols and guidelines to enhance palliative care's quality and uniformity, ultimately improving patient-centered care in neurooncology.

Palliative care for in-patient malignant glioma patients in Germany

OBJECTIVE

Malignant gliomas impose a significant symptomatic burden on patients and their families. Current guidelines recommend palliative care for patients with advanced tumors within eight weeks of diagnosis, emphasizing early integration for malignant glioma cases. However, the utilization rate of palliative care for these patients in Germany remains unquantified. This study investigates the proportion of malignant glioma patients who either died in a hospital or were transferred to hospice care from 2019 to 2022, and the prevalence of in-patient specialized palliative care interventions.

METHODS

In this cross-sectional, retrospective study, we analyzed data from the Institute for the Hospital Remuneration System (InEK GmbH, Siegburg, Germany), covering 2019 to 2022. We included patients with a primary or secondary diagnosis of C71 (malignant glioma) in our analysis. To refine our dataset, we identified cases with dual-coded primary and secondary diagnoses and excluded these to avoid duplication in our final tally. The data extraction process involved detailed scrutiny of hospital records to ascertain the frequency of hospital deaths, hospice transfers, and the provision of complex or specialized palliative care for patients with C71-coded diagnoses. Descriptive statistics and inferential analyses were employed to evaluate the trends and significance of the findings.

RESULTS

From 2019 to 2022, of the 101,192 hospital cases involving malignant glioma patients, 6,129 (6% of all cases) resulted in in-hospital mortality, while 2,798 (2.8%) led to hospice transfers. Among these, 10,592 cases (10.5% of total) involved the administration of complex or specialized palliative medical care. This provision rate remained unchanged throughout the COVID-19 pandemic. Notably, significantly lower frequencies of complex or specialized palliative care implementation were observed in patients below 65 years (p < 0.0001) and in male patients (padjusted = 0.016). In cases of in-hospital mortality due to malignant gliomas, 2,479 out of 6,129 cases (40.4%) received specialized palliative care.

CONCLUSION

Despite the poor prognosis and complex symptomatology associated with malignant gliomas, only a small proportion of affected patients received advanced palliative care. Specifically, only about 10% of hospitalized patients with malignant gliomas, and approximately 40% of those who succumb to the disease in hospital settings, were afforded complex or specialized palliative care. This discrepancy underscores an urgent need to expand palliative care access for this patient demographic. Additionally, it highlights the importance of further research to identify and address the barriers preventing wider implementation of palliative care in this context.

Palliative Care in Neuro-oncology: an Update

PURPOSE OF REVIEW

While the benefits of palliative care for patients with cancer are well established, palliative care in neuro-oncology is still in its early stages. However, in recent years, there has been increasing attention drawn to the need for better palliative care for patients with brain tumors.

RECENT FINDINGS

There is a growing body of literature demonstrating the high symptom burden and significant supportive care and information needs of these patients and their caregivers. In the area of caregiver needs, the last 3 years has seen a more rapid growth in recognizing and characterizing these needs. However, there remains a knowledge gap regarding the optimal means of addressing these needs. In this article, we outline important recent advances in the literature on palliative care for patients with brain tumors and highlight areas in need of greater attention and investigation.

Comparison of healthcare utilization and life-sustaining interventions between patients with glioblastoma receiving palliative care or not: A population-based study

BACKGROUND

Palliative care has historically been under-utilized in patients with glioblastoma. Furthermore, literature on the utilization of healthcare and life-sustaining interventions during the late-stage of glioblastoma has been limited.

AIM

To identify and compare healthcare utilization and life-sustaining interventions between patients with glioblastoma who received palliative care and who did not based on patients identified retrospectively from Taiwan Cancer Registry between January 2007 and December 2017.

DESIGN

In this study, palliative care was defined on the basis of claims submitted to the National Health Insurance, which has a specific code for it. Variables included demographic characteristics, the utilization of healthcare services, and invasive life-sustaining interventions.

SETTING/PARTICIPANTS

Of the 1994 patients with glioblastoma identified, 1784 fulfilled the inclusion criteria, 613 (34%) of whom received palliative care.

RESULTS

The survival of patients with glioblastoma under palliative care was significantly longer than that of those without palliative care. Those without palliative care had significantly more frequent intensive care unit admissions and a longer cumulative length of intensive care unit stay. Regarding cardiopulmonary or respiratory treatments, patients without palliative care had significantly more invasive interventions than those with palliative care. Patients receiving palliative care had significantly lower odds than those without life-sustaining interventions.

CONCLUSIONS

Our retrospective analysis reveals that glioblastoma patients without palliative care had greater odds of receiving life-sustaining treatments within 1 year before their death, although no gains in survival as compared to those that received palliative care. These findings highlight the urgent need for palliative care in caring for patients with glioblastoma.

Low expression of Ki-67/MIB-1 labeling index in IDH wild type glioblastoma predicts prolonged survival independently by MGMT methylation status

PURPOSE

The Ki-67/MIB-1 labeling index (LI) is clinically used to differentiate between high and low-grade gliomas, while its prognostic value remains questionable. Glioblastoma (GBM) expressing wild-type isocitrate dehydrogenase IDH^wt, a relatively common malignant brain tumor in adults, is characterized by a dismal prognosis. Herein, we have retrospectively investigated the prognostic role of Ki-67/MIB-1-LI in a large group of IDH^wt GBM.

METHODS

One hundred nineteen IDH^wt GBM patients treated with surgery followed by Stupp's protocol in our Institution between January 2016 and December 2021 were selected. A cut-off value for Ki-67/MIB-1-LI was used with minimal p-value based approach.

RESULTS

A multivariate analysis showed that Ki-67/MIB-1-LI expression < 15% significantly correlated with a longer overall survival (OS), independently from the age of the patients, Karnofsky performance status scale, extent of surgery and O⁶-methylguanine (O6-MeG)-DNA methyltransferase promoter methylation status.

CONCLUSIONS

Among other studies focused on Ki-67/MIB-1-LI, this is the first observational study showing a positive correlation between OS of IDH^wt GBM patients and Ki-67/MIB-1-LI that we propose as a new predictive marker in this subtype of GBM.

Palliative care referral across the disease trajectory in high-grade glioma

PURPOSE

Adults with high-grade glioma (HGG), WHO grade III or IV, have substantial palliative care needs. Our aim was to determine occurrence, timing, and factors associated with palliative care consultation (PCC) in HGG at one large academic institution.

METHODS

HGG patients receiving care between 08/1/2011 and 01/23/2020 were identified retrospectively from a multi-center healthcare system cancer registry. Patients were stratified by any PCC (yes/no), and timing of initial PCC by disease phase: diagnosis (before radiation), during initial treatment (first-line chemotherapy/radiation), second-line treatment(s), or end-of-life (after last chemotherapy).

RESULTS

Of 621 HGG patients, 134 (21.58%) received PCC with the vast majority occurring during hospital admission [111 (82.84%)]. Of the 134, 14 (10.45%) were referred during the diagnostic phase; 35 (26.12%) during initial treatment; 20 (14.93%) during second-line treatment; and 65 (48.51%) during end of life. In multivariable logistic regression, only higher Charlson Comorbidity Index was associated with greater odds of PCC [OR 1.3 (95% CI 1.2-1.4), p < 0.01]; but not age or histopathology. Patients who received PCC prior to end of life had longer survival from diagnosis than those referred during end of life [16.5 (8, 24) months vs. 11 (4, 17); p < 0.01].

CONCLUSION

A minority of HGG patients ever received PCC, which primarily occurred in the inpatient setting, and nearly half during the end-of-life phase. Thus, only about one in ten patients in the entire cohort potentially received the benefits of earlier PCC despite earlier referral having an association with longer survival. Further studies should elucidate barriers and facilitators to early PCC in HGG.

Forecasting Molecular Features in IDH-Wildtype Gliomas: The State of the Art of Radiomics Applied to Neurosurgery

BACKGROUND

The fifth edition of the WHO Classification of Tumors of the Central Nervous System (CNS), published in 2021, marks a step forward the future diagnostic approach to these neoplasms. Alongside this, radiomics has experienced rapid evolution over the last several years, allowing us to correlate tumor imaging heterogeneity with a wide range of tumor molecular and subcellular features. Radiomics is a translational field focused on decoding conventional imaging data to extrapolate the molecular and prognostic features of tumors such as gliomas. We herein analyze the state-of-the-art of radiomics applied to glioblastoma, with the goal to estimate its current clinical impact and potential perspectives in relation to well-rounded patient management, including the end-of-life stage.

METHODS

A literature review was performed on the PubMed, MEDLINE and Scopus databases using the following search items: "radiomics and glioma", "radiomics and glioblastoma", "radiomics and glioma and IDH", "radiomics and glioma and TERT promoter", "radiomics and glioma and EGFR", "radiomics and glioma and chromosome".

RESULTS

A total of 719 articles were screened. Further quantitative and qualitative analysis allowed us to finally include 11 papers. This analysis shows that radiomics is rapidly evolving towards a reliable tool.

CONCLUSIONS

Further studies are necessary to adjust radiomics' potential to the newest molecular requirements pointed out by the 2021 WHO classification of CNS tumors. At a glance, its application in the clinical routine could be beneficial to achieve a timely diagnosis, especially for those patients not eligible for surgery and/or adjuvant therapies but still deserving palliative and supportive care.
