Palliative care in brain tumors

Illness understanding and religiousness in patients with recurrent glioblastoma

Background

Patients with glioblastoma (GBM) often have inaccurate perceptions of prognosis. Strong religious beliefs have been associated with limited illness understanding (IU) in patients with advanced cancer, but IU and religiousness have not been investigated in patients with GBM. The aim of this study was to evaluate the association between religiousness and spirituality and IU in patients with GBM.

Methods

Patients enrolled in a prospective multicenter study of recurrent GBM (Coping with Glioblastoma, NCT02375841). Within one month of medical visits discussing MRI scans showing GBM progression, patients completed study surveys containing published measures of IU and religiousness. IU was compared between participants with moderate or high versus slight or no religiousness based on several patient-reported prompts using Fisher's exact tests.

Results

Twenty-four patients completed surveys of religiousness and IU. IU was partial within our cohort. Fifteen participants (62.5%) acknowledged that their illness was terminal. Only 6 (25%) correctly acknowledged their prognosis (months). Eleven patients (46%) were moderately or very religious, while 9 (38%) were either slightly religious or not at all religious. High religiousness and spirituality were each associated with partial IU (P = .06 and P = .01, respectively). A belief that God could perform a miracle to cure them of cancer and a belief in sanctity through suffering were also each associated with partial IU.

Conclusions

This prospective study that suggests religiousness, including the belief in miracles and a belief in sanctification through suffering, might influence patients' IU. Further research is warranted to study this association.

Vagus nerve stimulation: Novel concept for the treatment of glioblastoma and solid cancers by cytokine (interleukin-6) reduction, attenuating the SASP, enhancing tumor immunity

Immuno-oncology, specifically immune checkpoint inhibitors (ICIs), has revolutionized cancer care with dramatic, long-term responses and increased survival, including patients with metastatic cancer to the brain. Glioblastomas, and other primary brain tumors, are refractory to ICIs as monotherapy or in combination with standard therapy. The tumor microenvironment (TME) poses multiple biological hurdles: blood-brain barrier, immune suppression, heterogeneity, and tumor infiltration. Genomic analysis of the senescence-associated secretory phenotype (SASP) and preclinical models of glioma suggest that an exciting approach would entail reprogramming of the glioma microenvironment, attenuating the pro-inflammatory, pro-tumorigenic cytokines of the SASP, especially interleukin-6 (IL-6). A testable hypothesis now proposed is to modulate the immune system by harnessing the body's 'inflammatory reflex' to reduce cytokines. Vagus nerve stimulation can activate T cell immunity by the cholinergic, α7nicotinic acetylcholine receptor agonist (α7nAchR), and suppress IL-6 systemically, as well as other pro-inflammatory cytokines of the SASP, interleukin -1β (IL-1β) and tumor necrosis factor-alpha (TNF-α). The hypothesis predicts that electrical activation of the vagus nerve, with cytokine reduction, in combination with ICIs, would convert an immune resistant ("cold") tumor to an immune responsive ("hot") tumor, and halt glioma progression. The hypothesis also envisions cancer as an immune "dysautonomia" whereby a therapeutic intervention, vagus nerve stimulation (VNS), resets the systemic and local cytokine levels. A prospective, randomized, phase II clinical trial, to confirm the hypothesis, is a logical, exigent, next step. Cytokine reduction by VNS could also be useful for other forms of human cancer, e.g., breast, colorectal, head and neck, lung, melanoma, ovarian, pancreatic, and prostate cancer, as the emerging field of "cancer neuroscience" shows a role for neural regulation of multiple tumor types. Because IL-6, and companion pro-inflammatory cytokines, participate in the initiation, progression, spread and recurrence of cancer, minimally invasive VNS could be employed to suppress glioma or cancer progression, while also mitigating depression and/or seizures, thereby enhancing quality of life. The current hypothesis reimagines glioma pathophysiology as a dysautonomia with the therapeutic objective to reset the autonomic nervous system and form an immune responsive state to halt tumor progression and prevent recurrence. VNS, as a novel method to control cancer, can be administered with ICIs, standard therapy, or in clinical trials, combined with emerging immunotherapy: dendritic cell, mRNA, or chimeric antigen receptor (CAR) T cell vaccines.

End-of-Life Inpatient Palliative Care for Glioblastoma Multiforme: Lessons Learned from One Case

Glioblastoma multiforme (GBM) is the most common malignant primary brain tumor with a poor prognosis and limited survival. Patients with GBM have a high demand for palliative care. In our present case, a 21-year-old female GBM patient received inpatient palliative care services including symptom management, mental and psychological support for the patient, psychosocial and clinical decision support for her family members, and pre- and post-death bereavement management for the family. Furthermore, we provided the family members with comprehensive psychological preparation for the patient's demise and assisted the patient's family throughout the mourning period.The aim of this study is to provide a reference and insights for the clinical implementation of palliative care for patients with malignant brain tumors.

Identifying research priorities and essential elements of palliative care services for people facing malignant brain tumors: A participatory co-design approach

Background

Primary malignant brain tumors (ie, brain cancer) impact the quality of life (QoL) for patients and care partners in disease-specific ways involving cognition and communication. Palliative care (PC) addresses patient/care partner QoL, but it is not known how PC may address the unique needs of brain cancer patients. The purpose of this project was to identify brain cancer PC research priorities using participatory co-design methods.

Methods

Participatory co-design included the formation of a longitudinal, collaborative advisory group, engagement frameworks, design-thinking processes, and social media-based engagement over a 1-year period. Community-identified brain cancer QoL needs and research priorities were mapped to proposed "essential elements" of brain cancer PC services.

Results

We engaged an estimated 500 patients, care partners, healthcare professionals, and others with an interest in QoL and PC services for people with malignant brain tumors. Research priorities included testing the early introduction of PC services designed to address the unique QoL needs of brain cancer patients and care partners. Essential elements of brain cancer PC include: (1) addressing brain cancer patients' unique range of QoL needs and concerns, which change over time, (2) tailoring existing services and approaches to patient needs and concerns, (3) enhancing the involvement of interprofessional care team members, and (4) optimizing timing for PC services. This was the first participatory research effort exploring brain cancer patient and care partner QoL needs and PC services.

Conclusions

The brain tumor community calls for research testing PC service models for patients that incorporate the "essential elements" of palliative care.

Advancements in Image-Based Models for High-Grade Gliomas Might Be Accelerated

The first half of 2022 saw the publication of several major research advances in image-based models and artificial intelligence applications to optimize treatment strategies for high-grade gliomas, the deadliest brain tumors. We review them and discuss the barriers that delay their entry into clinical practice; particularly, the small sample size and the heterogeneity of the study designs and methodologies used. We will also write about the poor and late palliation that patients suffering from high-grade glioma can count on at the end of life, as well as the current legislative instruments, with particular reference to Italy. We suggest measures to accelerate the gradual progress in image-based models and end of life care for patients with high-grade glioma.

Headache Management in Individuals with Brain Tumor

Headache occurs commonly in individuals diagnosed with cerebral neoplasm. Though the features of a brain tumor-associated headache may vary, a progressive nature of headache and a change in headache phenotype from a prior primary headache disorder often are identified. Pathophysiologic mechanisms proposed for headache associated with brain tumor include headache related to traction on pain-sensitive structures, activation of central and peripheral pain processes, and complications from surgical, chemotherapeutic and/or radiotherapy treatment(s). Optimization of headache management is important for an individual's quality of life. Treatments are based upon patient-specific goals of care and may include tumor-targeted medical and surgical interventions, as well as a multimodal headache treatment approach incorporating acute and preventive medications, nutraceuticals, neuromodulation devices, behavioral interventions, anesthetic nerve blocks, and lifestyles changes.
