Abstract
Background Patients with high-grade glioma have high palliative care needs, yet few receive palliative care consultation. This study aims to explore themes on (1) benefits of primary (delivered by neuro-oncologists) and specialty palliative care (SPC) and (2) barriers to SPC referral, according to a diverse sample of clinicians. Methods From September 2021 to May 2023, 10 palliative physicians and 10 neuro-oncologists were recruited via purposive sampling for diversity in geographic setting, seniority, and practice structure. Semistructured, 45-minute interviews were audio-recorded, professionally transcribed, and coded by 2 investigators. A qualitative, phenomenological approach to thematic analysis was used. Results Regarding primary palliative care, (1) neuro-oncologists have primary ownership of cancer-directed treatment and palliative management and (2) the neuro-oncology clinic is glioma patients' medical home. Regarding SPC, (1) palliative specialists' approach is beneficial even without disease-specific expertise; (2) palliative specialists have time to comprehensively address palliative needs; and (3) earlier SPC enhances its benefits. For referral barriers, (1) appointment burden can be mitigated with telehealth, home-based, and embedded palliative care; (2) heightened stigma associating SPC with hospice in a population with high death anxiety can be mitigated with earlier referral to promote rapport-building; and (3) lack of neuro-oncologic expertise among palliative specialists can be mitigated by emphasizing their role in managing nonneurologic symptoms, coping support, and anticipatory guidance. Conclusions These themes emphasize the central role of neuro-oncologists in addressing palliative care needs in glioma, without obviating the need for or benefits of SPC. Tailored models may be needed to optimize the balance of primary and specialty palliative care in glioma.

Suh KJ, Jung EH, Seo J, Ji SY, Hwang K, Han JH, Kim CY, Kim IA, Kim YJ. Current status of advance care planning, palliative care consultation, and end-of-life care in patients with glioblastoma in South Korea. Oncologist 2024:oyae159. [PMID: 38940449 DOI: 10.1093/oncolo/oyae159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Accepted: 04/17/2024] [Indexed: 06/29/2024] Open
Abstract
BACKGROUND Given the typical trajectory of glioblastoma, many patients lose decision-making capacity over time, which can lead to inadequate advance care planning (ACP) and end-of-life (EOL) care. We aimed to evaluate patients' current ACP and EOL care status. PATIENTS AND METHODS We conducted a cohort study on 205 patients referred to oncologists at a Korean tertiary hospital between 2017 and 2022. We collected information on sociodemographic factors, cancer treatment, palliative care consultation, ACP, legal documents on life-sustaining treatment (LST) decisions, and aggressiveness of EOL care. RESULTS With a median follow-up time of 18.3 months: 159 patients died; median overall survival: 20.3 months. Of the 159 patients, 11 (6.9%) and 63 (39.6%) had advance directive (AD) and LST plans, respectively, whereas 85 (53.5%) had neither. Among the 63 with LST plans, 10 (15.9%) and 53 (84.1%) completed their forms through self-determination and family determination, respectively. Of the 159 patients who died, 102 (64.2%) received palliative care consultation (median time: 44 days from the first consultation to death) and 78 (49.1%) received aggressive EOL care. Those receiving palliative care consultations were less likely to receive aggressive EOL care (83.3% vs 32.4%, P < .001), and more likely to use more than 3 days of hospice care at EOL (19.6% vs 68.0%, P < .001). CONCLUSIONS The right to self-determination remains poorly protected among patients with glioblastoma, with nearly 90% not self-completing AD or LST plan. As palliative care consultation is associated with less aggressive EOL care and longer use of hospice care, physicians should promptly introduce patients to ACP conversations and palliative care consultations.

Abstract
BACKGROUND Glioblastoma (GBM) is the most common devastating primary brain cancer in adults. In our clinical practice, median overall survival (mOS) of GBM patients seems increasing over time. METHODS To address this observation, we have retrospectively analyzed the prognosis of 722 newly diagnosed GBM patients, aged below 70, in good clinical conditions (i.e. Karnofsky Performance Status -KPS- above 70%) and treated in our department according to the standard of care (SOC) between 2005 and 2018. Patients were divided into two groups according to the year of diagnosis (group 1: from 2005 to 2012; group 2: from 2013 to 2018). RESULTS Characteristics of patients and tumors of both groups were very similar regarding confounding factors (age, KPS, MGMT promoter methylation status and treatments). Follow-up time was fixed at 24 months to ensure comparable survival times between both groups. Group 1 patients had a mOS of 19 months ([17.3-21.3]) while mOS of group 2 patients was not reached. The recent period of diagnosis was significantly associated with a longer mOS in univariate analysis (HR=0.64, 95% CI [0.51 - 0.81]), p < 0.001). Multivariate Cox analysis showed that the period of diagnosis remained significantly prognostic after adjustment on confounding factors (adjusted Hazard Ratio (aHR) 0.49, 95% CI [0.36-0.67], p < 0.001). CONCLUSION This increase of mOS over time in newly diagnosed GBM patients could be explained by better management of potentially associated non-neurological diseases, optimization of validated SOC, better management of treatments side effects, supportive care and participation in clinical trials.

Abstract
Glioblastoma (GB) is a rare but extremely aggressive brain tumor that significantly impacts patient outcomes, affecting both duration and quality of life. The protocol established by Stupp and colleagues in 2005, based on radiotherapy and chemotherapy with Temozolomide, following maximum safe surgical resection remains the gold standard for GB treatment; however, it is evident nowadays that the extreme intratumoral and intertumoral heterogeneity, as well as the invasiveness and tendency to recur, of GB are not compatible with a routine and unfortunately ineffective treatment. This review article summarizes the main challenges in the search for new valuable therapies for GB and focuses on the impact that extracellular vesicle (EV) research and exploitation may have in the field. EVs are natural particles delimited by a lipidic bilayer and filled with functional cellular content that are released and uptaken by cells as key means of cell communication. Furthermore, EVs are stable in body fluids and well tolerated by the immune system, and are able to cross physiological, interspecies, and interkingdom barriers and to target specific cells, releasing inherent or externally loaded functionally active molecules. Therefore, EVs have the potential to be ideal allies in the fight against GB and to improve the prognosis for GB patients. The present work describes the main preclinical results obtained so far on the use of EVs for GB treatment, focusing on both the EV sources and molecular cargo used in the various functional studies, primarily in vivo. Finally, a SWOT analysis is performed, highlighting the main advantages and pitfalls of developing EV-based GB therapeutic strategies. The analysis also suggests the main directions to explore to realize the possibility of exploiting EVs for the treatment of GB.

Abstract
Background Glioblastoma Multiforme is a deadly brain cancer that is very challenging for patients and their families. It is associated with rapid progression, cognitive decline, and a low survival rate. Objective To determine whether deceased Glioblastoma Multiforme patients had received follow-up service from the palliative care team before their death, whether invasive measures had been reduced, and whether the last antineoplastic treatment was given within 14-30 days before death. Method A retrospective study utilizing chart data from January 2020 to March 2022 from an institutional project. Data were gathered to reflect selected indicators of quality of care for palliative care patients. Results Of the 30 hospitalized patients with Glioblastoma Multiforme who had died while in hospital, 50% had received support from the palliative care team. Two patients (6.7%) had undergone antineoplastic treatment in the last 14 days of life and 13 (43.3%) had an order limiting invasive measures defined in the last two weeks of life. Conclusion In half of the patients monitored by a palliative care team, antineoplastic treatment and limitation of invasive measures occurred in the last 14 days of life. This may be associated with increased suffering of patients, family members, and professionals. Discussions about end-of-life care-related choices and goals of care need to be respected.

Abstract
Contexte Le glioblastome multiforme est un cancer du cerveau mortel très éprouvant pour les patients et leur famille. Il se caractérise par une progression rapide, un déclin cognitif et un faible taux de survie. Objectif Déterminer si les patients morts d’un glioblastome multiforme ont été suivis par l’équipe des soins palliatifs avant leur décès, si les soins invasifs ont été réduits, et si le dernier traitement antinéoplasique a été administré entre 14 et 30 jours avant le décès. Méthode En procédant à une étude rétrospective à partir de dossiers datés de janvier 2020 à mars 2022 tirés d’un projet mené par l’établissement hospitalier, on a recueilli les données permettant d’observer les indicateurs sélectionnés sur la qualité des soins palliatifs. Résultat Des 30 patients hospitalisés pour un glioblastome multiforme et décédés à l’hôpital, 50 % avaient été vus par l’équipe de soins palliatifs. Deux (6,7 %) avaient reçu un traitement antinéoplasique dans les 14 derniers jours de vie et 13 (43,3 %) avaient bénéficié d’une limitation des soins invasifs dans les deux dernières semaines de vie. Conclusion Pour la moitié des patients suivis par une équipe de soins palliatifs, l’arrêt du traitement antinéoplasique et la limitation des soins invasifs sont survenus au cours des 14 derniers jours de vie. Cela peut accroître la souffrance des patients et des membres de la famille, et complexifier le travail des professionnels de la santé. Il faut discuter des soins de fin de vie et de leurs objectifs avec les patients et respecter leurs choix.

Abstract
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.

Abstract
BACKGROUND End-of-life in patients with brain cancer presents special challenges, and palliative care approach is underutilized. Patients with brain cancer, in the last months of life, receive frequent hospital readmissions, highlighting bad end-of-life care quality. Early integration of palliative care improves quality of care in advanced stage of disease and patient's quality of death. PURPOSE We retrospectively analyzed a consecutive series of patients with brain cancer discharged after diagnosis to evaluate pattern of treatment and rate of hospital readmission in the last months of life. DESIGN Data were collected from the Lazio Region Healthcare database. SETTING Adult patients discharged with diagnosis ICD-9 191.* between January 1, 2010, and December 31, 2019 were included. RESULTS A total of 6672 patients were identified, and 3045 deaths were included. In the last 30 days 33% were readmitted to the hospital and 24.2% to the emergency room. 11.7% were treated with chemotherapy and 6% with radiotherapy. Most indicators of end-of-life care showed wide variability by hospital of discharge. CONCLUSIONS Strategies to improve quality of care at the end of life and to decrease re-hospitalization and futile treatments are becoming increasingly important to improve quality of death and reduce healthcare costs. Variability observed by hospital of discharge indicates the lack of a standard approach to end-of-life care.

Abstract
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.

Abstract
BACKGROUND High-grade glioma has a poor overall survival with profoundly negative effects on the patient's quality of life and their caregivers. In this study, we investigate the factors associated with receiving palliative care in patients diagnosed with glioblastoma (GBM) and the association of receiving or not receiving palliative care with overall survival. METHODS The National Cancer Database was analyzed for patterns of care in patients ≥18 years old who were diagnosed with histologically confirmed grade IV GBM between 2004 and 2017. All statistical analyses were conducted based on univariate and multivariate regression models. RESULTS A total of 85,380 patients with the diagnosis of GBM were identified. Of the study population, 2803 patients (3.28%) received palliative therapy. On multivariate logistic regression analysis, age ≥70 years (odds ratio [OR], 1.28; 95% confidence interval [CI], 1.04-1.58; P < 0.001), Medicare (OR, 1.348; CI, 1.13-1.61; P = 0.001), tumor size ≥5 cm (OR, 1.15; CI, 1.01-1.31; P = 0.036), tumor multifocality (OR, 1.69; CI, 1.47-1.96; P < 0.001), lobe overlapping tumor (OR, 2.09; CI, 1.13-3.86; P = 0.018), Charlson-Deyo score >0, receiving treatment at a nonacademic/research program, and medium volume of cancers managed at the treatment facility (OR, 1.19; CI, 1.02-1.38; P = 0.026) were independent risk factors associated with an increased chance of receiving palliative care. In contrast, a household income of ≥$40,227 and high volume of cancer managed at the treatment facility (OR, 0.75; CI, 0.58-0.96; P = 0.02) were independent risk factors associated with decreased palliative care. Patients who received no palliative care had a 2-year overall survival longer than those who received palliative care (22% vs. 8.8%; P < 0.001). In patients receiving palliative care, those who received recommended treatment had a 2-year overall survival longer than those who declined part or whole recommended treatment (9.1% vs. 3.8%; P = 0.009). CONCLUSIONS In patients with high-grade glioma, receiving palliative care is associated with decreased survival. When receiving palliative care, recommended treatment increases the number of patients who survive more than 2 years approximately 3-fold compared with those declining part or whole treatment.

Abstract
OBJECTIVE WHO grade III meningiomas, also known as malignant meningiomas (MMs), are rare, and the heterogenous clinical course in patients with MM is not well described. To characterize the clinical course of patients with MM, granular clinical data were gathered from 51 patients treated at the Department of Neurosurgery and Radiation Oncology, Rigshospitalet, in Copenhagen, Denmark, between 2000 and 2020. METHODS The authors investigated outcome and timing in terms of 1) tumor progression and grade transformation in patients previously diagnosed with WHO grade I or II meningiomas (patients with a secondary MM [sMM]); 2) performance status and complications following surgery; and 3) transition to noncurative treatment and ultimately death. Complications, time between recurrences, and outcome (modified Rankin Scale [mRS] score) for every surgery were analyzed, both malignant and premalignant. RESULTS Of the 51 patients, 24 (47%) had an sMM. The time to WHO grade III transformation in the sMM group varied widely (median 5.5 years, range 0.5-22 years), but after transformation to a WHO grade III tumor, patients with an sMM and those with a primary MM (pMM) did not differ significantly in overall survival and cumulative risk of progression. Median overall survival for all 51 patients was 4.2 years (95% CI 2.6-7.2 years). Time from the decision to shift from curative to noncurative treatment until death was 3.8 months and the 30-day mortality rate following surgery was 11.8%. From a cumulative number of 151 surgeries, 10 surgeries were followed by improvement on the mRS, mRS score was unchanged in 70, and it worsened in 71. The MM was the underlying cause of death in 30 of 31 patients who had died at the end of follow-up. CONCLUSIONS Together, these findings clearly show a significant morbidity and mortality from the disease itself and from the treatment. These findings warrant studies of prognostic factors for earlier support and adjuvant measures in MM and identify a need for better palliative strategies in this patient group.

Abstract
Background Glioblastoma (GBM) carries a poor prognosis despite standard of care. Early palliative care (PC) has been shown to enhance survival and quality of life while reducing healthcare costs for other cancers. This study investigates differences in PC timing on outcomes for patients with GBM. Methods This study used Surveillance, Epidemiology, and End Results (SEER)-Medicare data from 1997 to 2016. Based on ICD codes, three groups were defined: (1) early PC within 10 weeks of diagnosis, (2) late PC, and (3) no PC. Outcomes were compared between the three groups. Results Out of 10 812 patients with GBM, 1648 (15.24%) patients had PC consultation with an overall positive trend over time. There were no significant differences in patient characteristics. The late PC group had significantly higher number of hospice claims (1.06 ± 0.69) compared to those without PC, in the last month of life. There were significant differences in survival among the three groups (P < .0001), with late PC patients with the longest mean time to death from diagnosis (11.72 ± 13.20 months). Conclusion We present the first investigation of PC consultation prevalence and outcomes, stratified by early versus late timing, for adult GBM patients. Despite an overall increase in PC consultations, only a minority of GBM patients receive PC. Patients with late PC had the longest survival times and had greater hospice use in the last month of life compared to other subgroups. Prospective studies can provide additional valuable information about this unique population of patients with GBM.

Abstract
Glioblastoma multiforme represent > 50% of primary gliomas and have five year survival rates of ~ 5%. Maximal safe surgical resection followed by radiotherapy with concurrent and adjuvant temozolomide remains the standard treatment since published by Stupp et al. (in N Engl J Med 352:987-996, 2005), with additional benefit for patients with MGMT-methylated tumors. We review the current treatment landscape and ongoing efforts to improve these outcomes. An extensive literature search of Pubmed and Google Scholar involving the search terms "glioblastoma," "glioblastoma multiforme," or "GBM" for papers published to July 2021 was conducted and papers evaluated for relevance. As well as current data that informs clinical practice, we review ongoing clinical research in both newly diagnosed and recurrent settings that provides hope for a breakthrough. The Stupp protocol remains standard of care in 2021. Addition of tumor treating fields improved mOS modestly, with benefit seen in MGMT-methylated and unmethylated cohorts and also improved time to cognitive decline but has not been widely adopted. The addition of lomustine to temozolomide, in MGMT-methylated patients, also showed a mOS benefit but further investigation is required. Other promising therapeutic strategies including anti-angiogenic therapy, targeted therapy, and immunotherapy have yet to show a survival advantage. Improvements in the multidisciplinary management, surgical techniques and equipment, early palliative care, carrier support, and psychological support may be responsible for improving survival over time. Despite promising preclinical rationale, immunotherapy and targeted therapy are struggling to impact survival. A number of ongoing clinical trials provide hope for a breakthrough.

Abstract
Purpose The care of older neurosurgical patients at the end life is a particularly demanding challenge. Especially, the specific needs of very old patients with glioblastoma at the end of life are at risk of being deprived of adequate care. Methods Based on a narrative literature review, this article aims to explore key issues of the thematic intersection of geriatric glioblastoma patients, palliative care and neurosurgery. Results and discussion Four key issues were identified: patient-centeredness (need orientation and decision making), early palliative care, advance care planning, and multi-professionalism. Possible benefits and barriers are highlighted with regard to integrating these concepts into neurosurgery. Conclusions Palliative care complements neurosurgical care of geriatric glioblastoma multiforme patients to optimise care for this highly vulnerable category of patients.

Abstract
PURPOSE OF REVIEW High-grade gliomas (HGG) are rare brain tumors that cause disproportionate suffering and mortality. Palliative care, whose aim is to relieve the symptoms and stressors of serious illness, may benefit patients with HGG and their families. In this review, we summarize the extant literature and provide recommendations for addressing the symptom management and communication needs of brain tumor patients and their caregivers at key points in the illness trajectory: initial diagnosis; during upfront treatment; disease recurrence; end-of-life period; and after death during bereavement. RECENT FINDINGS Patients with HGG experience highly intrusive symptoms, cognitive and functional decline, and emotional and existential distress throughout the disease course. The caregiver burden is also substantial during the patient's illness and after death. There is limited evidence to guide the palliative management of these issues. Palliative care is likely to benefit patients with HGG, yet further research is needed to optimize the delivery of palliative care in neuro-oncology.

Abstract
BACKGROUND Primary malignant brain tumours can have an unpredictable course, but high-grade gliomas typically have a relentlessly progressive disease trajectory. They can cause profound symptom burden, affecting physical, neurocognitive, and social functioning from an early stage in the illness. This can significantly impact on role function and on the experiences and needs of informal caregivers. Access to specialist palliative and supportive care early in the disease trajectory, for those with high-grade tumours in particular, has the potential to improve patients' and caregivers' quality of life. However, provision of palliative and supportive care for people with primary brain tumours - and their informal caregivers - is historically ill-defined and ad hoc, and the benefits of early palliative interventions have not been confirmed. It is therefore important to define the role and effectiveness of early referral to specialist palliative care services and/or the effectiveness of other interventions focused on palliating disease impact on people and their informal caregivers. This would help guide improvement to service provision, by defining those interventions which are effective across a range of domains, and developing an evidence-based model of integrated supportive and palliative care for this population. OBJECTIVES To assess the evidence base for early palliative care interventions, including referral to specialist palliative care services compared to usual care, for improving outcomes in adults diagnosed with a primary brain tumour and their carers. SEARCH METHODS We conducted searches of electronic databases, CENTRAL, MEDLINE, CINAHL, Web of Science, and PsycINFO (last searched 16 November 2021). We conducted searches to incorporate both qualitative and quantitative search terms. In addition to this, we searched for any currently recruiting trials in ClinicalTrials.gov and in the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) search portal, and undertook citation tracking via Scopus. We also handsearched reference lists of potentially eligible systematic review articles to identify any other relevant studies, contacted experts in the field and searched key authors via Web of Science and searched SIGLE (System of Information on Grey Literature in Europe). SELECTION CRITERIA We included studies looking at early referral to specialist palliative care services - or early targeted palliative interventions by other healthcare professionals - for improving quality of life, symptom control, psychological outcomes, or overall survival as a primary or secondary outcome measure. Studies included randomised controlled trials (RCTs), non-randomised studies (NRS), as well as qualitative and mixed-methods studies where both qualitative and quantitative data were included. Participants were adults with a confirmed radiological and/or histological diagnosis of a primary malignant brain tumour, and/or informal adult carers (either at individual or family level) of people with a primary malignant brain tumour. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methodological procedures for data extraction, management, and analysis. We used GRADE to assess the certainty of the evidence for symptom control, i.e. cognitive function. MAIN RESULTS We identified 9748 references from the searches, with 8337 remaining after duplicates were removed. After full-text review, we included one trial. There were no studies of early specialist palliative care interventions or of early, co-ordinated generalist palliative care approaches. The included randomised trial addressed a single symptom area, focusing on early cognitive rehabilitation, administered within two weeks of surgery in a mixed brain tumour population, of whom approximately half had a high-grade glioma. The intervention was administered individually as therapist-led computerised exercises over 16 one-hour sessions, four times/week for four weeks. Sessions addressed several cognitive domains including time orientation, spatial orientation, visual attention, logical reasoning, memory, and executive function. There were no between-group differences in outcome for tests of logical-executive function, but differences were observed in the domains of visual attention and verbal memory. Risk of bias was assessed and stated as high for performance bias and attrition bias but for selective reporting it was unclear whether all outcomes were reported. We considered the certainty of the evidence, as assessed by GRADE, to be very low. AUTHORS' CONCLUSIONS Currently there is a lack of research focusing on the introduction of early palliative interventions specifically for people with primary brain tumours, either as co-ordinated specialist palliative care approaches or interventions focusing on a specific aspect of palliation. Future research should address the methodological shortcomings described in early palliative intervention studies in other cancers and chronic conditions. In particular, the specific population under investigation, the timing and the setting of the intervention should be clearly described and the standardised palliative care-specific components of the intervention should be defined in detail.

Abstract
Background Management of patients with brain tumors can lead to ethical and decisional dilemmas. The aim of this study was to characterize ethical conflicts encountered in neuro-oncologic patients. Methods Retrospective review of ethics consultations performed upon patients with primary and metastatic brain tumors at a tertiary cancer center. An ethics consultation database was examined to characterize ethical conflicts, contextual factors, and interventions by the consultation team. Results Fifty consultations were reviewed; 28 (56%) patients were women, median age 54 (range 4-86); 27 (54%) patients had a primary central nervous system malignancy; 20 (40%) had brain metastasis. At the time of consultations, 41 (82%) patients lacked decisional capacity; 48 (96%) had a designated surrogate decision maker; 3 (6%) had an advance directive outlining wishes regarding medical treatment; 12 (24%) had a Do Not Attempt Resuscitation (DNAR) order. Ethical conflicts centered upon management of end-of-life (EOL) circumstances in 37 (72%) of cases; of these, 30 did not have decisional capacity. The most common ethical issues were DNAR status, surrogate decision making, and request for nonbeneficial treatment. Consultants resolved conflicts by facilitating decision making for incapacitated patients in 30 (60%) cases, communication between conflicting parties in 10 (20%), and re-articulation of patients' previously stated wishes in 6 (12%). Conclusions Decisional capacity at EOL represents the primary ethical challenge in care of neuro-oncologic patients. Incomplete awareness among surrogate decision makers of patients' prognosis and preferences contributes to communication gaps and dilemmas. Early facilitation of communication between patients, caregivers, and medical providers may prevent or mitigate conflicts and allow the enactment of patients' goals and values.

Abstract
The aim of the study is to evaluate the efficacy of the combination of Raman spectroscopy with feature engineering and machine learning algorithms for detecting glioma patients. In this study, we used Raman spectroscopy technology to collect serum spectra of glioma patients and healthy people and used feature engineering-based classification models for prediction. First, to reduce the dimensionality of the data, we used two feature extraction algorithms which are partial least squares (PLS) and principal component analysis (PCA). Then, the principal components were selected using the feature selection methods of four correlation indexes, namely, Relief-F (RF), the Pearson correlation coefficient (PCC), the F-score (FS) and term variance (TV). Finally, back-propagation neural network (BP), linear discriminant analysis (LDA) and support vector machine (SVM) classification models were established. To improve the reliability of the model, we used a fivefold cross validation to measure the prediction performance between different models. In this experiment, 33 classification models were established. Integrating 4 classification criteria, PLS-Relief-F-BP, PLS-F-Score-BP, PLS-LDA and PLS-Relief-F-SVM had better effects, and their accuracy rates reached 97.58%, 96.33%, 97.87% and 96.19%, respectively. The experimental results show that feature engineering can select more representative features, reduce computational time complexity and simplify the model. The classification model established in this experiment can not only increase the robustness of the model and shorten the discrimination time but also realize the rapid, stable and accurate diagnosis of glioma patients, which has high clinical application value.

Abstract
Glioblastoma (GBM) has a median overall survival of 16-21 months. As patients with GBM suffer concurrently from terminal cancer and a disease with progressive neurocognitive decline, advance care planning (ACP) and palliative care (PC) are critical. We conducted a systematic review exploring published literature on the prevalence of ACP, end-of-life (EOL) services utilization (including PC services), and experiences among adults with GBM. We searched from database inception until 20 December 2020. Preferred reporting items for systematic reviews guidelines were followed. Included studies were assessed for quality using the Newcastle-Ottawa Scale. The 16 articles were all nonrandomized studies conducted in six countries with all but two published in 2014 or later. ACP documentation varied from 4-55%, PC referral was pursued in 39-40% of cases, and hospice referrals were made for 66-76% of patients. Hospitalizations frequently occurred at the EOL with 20-56% of patients spending over 25% of their overall survival time hospitalized. Many GBM patients do not pursue ACP or have access to PC. There is a dearth of focused and high-quality studies on ACP, PC, and hospice use among adults with GBM. Prospective studies that address these and additional aspects related to EOL care, such as healthcare costs and inpatient supportive care needs, are needed.

Timing of Palliative Care Referral Before and After Evidence from Trials Supporting Early Palliative Care. Oncologist 2021; 26:332-340. [PMID: 33284483 DOI: 10.1002/onco.13625] [Citation(s) in RCA: 30] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Accepted: 11/20/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Evidence from randomized controlled trials has demonstrated benefits in quality of life outcomes from early palliative care concurrent with standard oncology care in patients with advanced cancer. We hypothesized that there would be earlier referral to outpatient palliative care at a comprehensive cancer center following this evidence. MATERIALS AND METHODS Administrative databases were reviewed for two cohorts of patients: the pre-evidence cohort was seen in outpatient palliative care between June and November 2006, and the post-evidence cohort was seen between June and November 2015. Timing of referral was categorized, according to time from referral to death, as early (>12 months), intermediate (>6 months to 12 months), and late (≤6 months from referral to death). Univariable and multivariable ordinal logistic regression analyses were used to determine demographic and medical factors associated with timing of referral. RESULTS Late referrals decreased from 68.8% pre-evidence to 44.8% post-evidence; early referrals increased from 13.4% to 31.1% (p < .0001). The median time from palliative care referral to death increased from 3.5 to 7.0 months (p < .0001); time from diagnosis to referral was also reduced (p < .05). On multivariable regression analysis, earlier referral to palliative care was associated with post-evidence group (p < .0001), adjusting for shorter time since diagnosis (p < .0001), referral for pain and symptom management (p = .002), and patient sex (p = .04). Late referrals were reduced to <50% in the breast, gynecological, genitourinary, lung, and gastrointestinal tumor sites. CONCLUSIONS Following robust evidence from trials supporting early palliative care for patients with advanced cancer, patients were referred substantially earlier to outpatient palliative care. IMPLICATIONS FOR PRACTICE Following published evidence demonstrating the benefit of early referral to palliative care for patients with advanced cancer, there was a substantial increase in early referrals to outpatient palliative care at a comprehensive cancer center. The increase in early referrals occurred mainly in tumor sites that have been included in trials of early palliative care. These results indicate that oncologists' referral practices can change if positive consequences of earlier referral are demonstrated. Future research should focus on demonstrating benefits of early palliative care for tumor sites that have tended to be omitted from early palliative care trials.
