Brain metastases (BMs) account for a disproportionately high percentage of cancer morbidity and mortality. Historically, studies have focused on improving survival outcomes, and recent radiation oncology clinical trials have incorporated HRQOL and cognitive assessments. We are now equipped with a battery of assessments in the radiation oncology clinic, but there is a lack of consensus regarding how to incorporate them in modern clinical practice. Herein, we present validated assessments for BM patients, current recommendations for future clinical studies, and treatment advances that have improved HRQOL and cognitive outcomes for BM patients.

Purpose: To investigate the toxicity profile and establish an optimal dosing schedule of zotiraciclib with temozolomide in patients with recurrent high-grade astrocytoma.Patients and Methods: This two-stage phase I trial determined the MTD of zotiraciclib combined with either dose-dense (Arm1) or metronomic (Arm2) temozolomide using a Bayesian Optimal Interval design; then a randomized cohort expansion compared the progression-free survival rate at 4 months (PFS4) of the two arms for an efficient determination of a temozolomide schedule to combine with zotiraciclib at MTD. Pharmacokinetic and pharmacogenomic profiling were included. Patient-reported outcome was evaluated by longitudinal symptom burden.Results: Fifty-three patients were enrolled. Dose-limiting toxicities were neutropenia, diarrhea, elevated liver enzymes, and fatigue. MTD of zotiraciclib was 250 mg in both arms and thus selected for the cohort expansion. Dose-dense temozolomide plus zotiraciclib (PSF4 40%) compared favorably with metronomic temozolomide (PFS4 25%). Symptom burden worsened at cycle 2 but stabilized by cycle 4 in both arms. A significant decrease in absolute neutrophil count and neutrophil reactive oxygen species production occurred 12–24 hours after an oral dose of zotiraciclib but both recovered by 72 hours. Pharmacokinetic/pharmacogenomic analyses revealed that the CYP1A2_5347T>C (rs2470890) polymorphism was associated with higher AUCinf value.Conclusions: Zotiraciclib combined with temozolomide is safe in patients with recurrent high-grade astrocytomas. Zotiraciclib-induced neutropenia can be profound but mostly transient, warranting close monitoring rather than treatment discontinuation. Once validated, polymorphisms predicting drug metabolism may allow personalized dosing of zotiraciclib.

Background and Objectives Financial toxicity significantly affects many patients, especially cancer survivors. We evaluated the association of unemployment as a major contributor to financial toxicity with patient-reported outcomes (PROs) assessing multiple illness experience domains in a primary CNS tumor (PCNST) cohort. Methods Patient and disease characteristics and PROs measuring symptom burden, interference, psychologic distress, functional impairment, and health-related quality of life (HRQOL) from participants enrolled in an institutional review board–approved observational study at the US NIH9s Neuro-Oncology Branch were collected between September 2016 and December 2019. Descriptive statistics, tests of association, and comparison of group mean values were used to describe and evaluate PROs. Results Of the 277 participants diagnosed with a PCNST, 57% were male and 43% were female. Participants reported their race as White, non-Hispanic (78%); White, Hispanic/Latino (9%); Asian (7%); Black (4%); Native Hawaiian/Pacific Islander (1%); and other (2%) with 8% missing. The median age of the overall cohort was 45 years (range 18–74). Hispanic participants in the overall sample were 2.3 times more likely, and in the brain tumor group 3.2 times more likely, to report unemployment (p = 0.043, odds ratio [OR] 2.3, 95% CI 1.0–5.4 and p = 0.008, OR 3.2, 95% CI 1.3–7.9, respectively). 77 (28%) individuals unemployed due to tumor reported more functional impairment with walking, washing, dressing, and performing usual activities and reduced HRQOL (p < 0.001). More unemployed participants in the total sample reported moderate-to-severe depressive symptoms (25%) than those employed (8%) (χ2(1) = 13.9, p < 0.001, OR 3.7, 95% CI 1.8–7.8) and more moderate-to-severe anxiety symptoms (30%) than those employed (15%) (χ2(1) = 7.8, p = 0.005, OR 2.4, 95% CI 1.3–4.5). Unemployed participants with brain tumor reported on average 3 more symptoms as moderate-to-severe compared with those employed (t(83) = −4.0, 95% CI difference −5 to −2, p < 0.001, Hedge g = 0.70). Discussion Being unemployed due to a PCNST strongly correlated with high symptom burden, functional impairment, psychological distress, and reduced HRQOL, which may be impediments to returning to work that warrant intervention. Lack of employer-based health insurance and reduced earnings are financial sequelae of unemployment superimposed on the physical, social, and cognitive effects of living with a PCNST. Innovations to screen for and address financial toxicity and its contributing factors are needed.

Survivorship has become a significant topic within oncologic care. The tools and means by which the provision of survivorship care can be implemented and delivered are in development and are the focus of significant research oncology-wide. These tools and methods include innovations of survivorship care delivery, survivorship care plans, and improving communication among all stakeholders in an individual patient’s care as the means to elevate health-related quality of life. The merits of these survivorship care provisions in the field of neuro-oncology and its patients’ exigent need for more patient-centric care focused on living with their illness are discussed. Since 2014 there has been a mandate within the United States for adult cancer patients treated with curative intent to receive survivorship care plans, comprising a treatment summary and a follow-up plan, intended to facilitate patients’ care after initial diagnosis and upfront treatment. Several cancer-specific survivorship care plans have been developed and endorsed by health care professional organizations and patient advocacy groups. A survivorship care plan specific for neuro-oncology has been collaboratively developed by a multidisciplinary and interprofessional committee; it is endorsed by the Society for Neuro-Oncology Guidelines Committee. It is available as open access for download from the Society for Neuro-Oncology website under “Resources”: https://www.soc-neuro-onc.org/SNO/Resources/Survivorship_Care_Plan.aspx. Survivorship care offers an opportunity to begin directly addressing the range of issues patients navigate throughout their illness trajectory, an oncology initiative to which neuro-oncology patients both need and deserve equitable access.

Cancer patient survivorship has become a significant topic within oncology care for both adult and pediatric patients. Starting in 2005, the Institute of Medicine recommended the use of survivorship care plans to assist patients transitioning from active treatment to the posttreatment phase of their cancer care, a critical time for many patients. Since 2014 there has been a mandate within the United States for adult cancer patients treated with curative intent to receive survivorship care plans comprised of a treatment summary and a follow-up plan to facilitate a better understanding among patients of what to expect after treatment. In addition to a general oncology survivorship care plan, specific care plans have been created for breast, lung, prostate, and colon cancers, as well as lymphoma. A survivorship care plan specific to adult neuro-oncology has been developed by a multidisciplinary and interprofessional committee, with approval from the Society for Neuro-Oncology Guidelines Committee. It has been published in compendium with this review of survivorship care planning and available as a fillable PDF on the Society of Neuro-Oncology Guidelines Endorsement web page (https://www.soc-neuro-onc.org/SNO/Resources/Survivorship_Care_Plan.aspx). Implementation of this survivorship care plan provides a unique opportunity to begin addressing the range of survivorship issues our neuro-oncology patients navigate from diagnosis to end of life.
