Effects of low-dose naltrexone on quality of life in high-grade glioma patients: a placebo-controlled, double-blind randomized trial.

PURPOSE: At diagnosis and throughout the disease course, patients with high-grade glioma (HGG) experience a diminished quality of life (QOL) and increased fatigue. Naltrexone, an orally semisynthetic opiate antagonist, is FDA-approved for the treatment of heroin/alcohol addiction, and low-dose naltrexone (LDN) has been observed to improve QOL and lower fatigue in other neurological illnesses, such as multiple sclerosis. LDN is believed to function as a partial agonist and can lead to shifts in neurochemicals that reduce fatigue. Based on this, we sought to study whether LDN has an impact on QOL and fatigue in patients with HGG. METHODS: In a placebo-controlled, double-blind study, we randomized 110 HGG patients to receive placebo (N = 56) or LDN 4.5 mg orally at night (N = 54). Subjects received LDN or placebo at day 1 of concurrent radiation and temozolomide therapy and continued for 16 weeks. Change from baseline in patient-reported outcomes of QOL (Functional Assessment of Cancer Therapy-Brain) and fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue) was assessed. RESULTS: Demographics were WHO grade IV (85%), male (56%), KPS 90-100 (51%), grossly resected (55%), and mean age of 56 years. QOL and fatigue changes between baseline and post concurrent chemotherapy and radiation therapy were not significantly different between patients receiving LDN or placebo. The adverse event profiles for LDN and placebo were similar and attributed to concomitant use of temozolomide. CONCLUSIONS: LDN has no effect on QOL and fatigue in HGG patients during concurrent chemotherapy and radiation therapy.

Spiritual well-being and its association with health-related quality of life in primary brain tumor patients.

BACKGROUND: Spirituality can impact patients' attitudes and decisions about treatment and end-of-life care when coping with cancer. Previous studies documented health-related quality of life (HRQoL) and spiritual well-being (SWB) as positively correlated within a general cancer patient population, but little is known about their association in the primary brain tumor population. We sought to measure SWB in primary brain tumor patients and evaluate whether it was associated with HRQoL. METHODS: Six-hundred and six patients treated at The Preston Robert Tisch Brain Tumor Center at Duke between December 16, 2013 and February 28, 2014 with data in the PRoGREss registry are included in this retrospective analysis. Each patient completed the Functional Assessment of Chronic Illness Therapy-Spiritual Well-Being 12 (FACIT-Sp-12) and -Fatigue (FACIT-F), and the Functional Assessment of Cancer Therapy-General and -Brain (FACT-G and FACT-Br). RESULTS: Mean age was 49.1 years (SD = 13.5 years), male (N = 328, 54.1%), married (N = 404, 66.7%), at least college-educated (N = 381, 62.9%), and diagnosed with a high-grade glioma (N = 412, 68.0%). Multiple regression analyses were performed on both the FACT-G and the FACT-Br using the FACIT-Sp-12 sub-scales of Meaning/Peace and Faith, FACIT-F, belief in God or a higher power, prayer, gender, tumor grade, and Karnofsky Performance Status (KPS) as predictors. We found that greater SWB (measured by FACIT-Sp-12) was associated with better HRQoL (measured by FACT-G and FACT-Br; p < .0001). CONCLUSION: The association between reported SWB and reported improved HRQoL emphasizes the importance of spirituality in primary brain tumor patients, suggesting SWB must be considered in strategies to improve HRQoL.

Complementary and integrative health interventions and their association with health-related quality of life in the primary brain tumor population.

BACKGROUND AND PURPOSE: Little is known about complementary and integrative health intervention usage in the primary brain tumor population. We aimed to identify the percentage of patients using these practices and explore the impact on quality of life. MATERIALS AND METHODS: Clinical records from patients seen in clinic between December 16, 2013 and February 28, 2014 were reviewed retrospectively. The questionnaires used were a modified version of the International Complementary and Alternative Medicine Questionnaire, the Functional Assessment of Cancer Therapy- Brain Cancer and the Functional Assessment of Chronic Illness Therapy- Fatigue. RESULTS: 76% of patients utilized a complementary and integrative health modality. The most frequently reported modalities used were vitamins, massage, and spiritual healing, prayer, diet and meditation. CONCLUSION: These results confirm the usage of complementary and integrative health practices within the primary brain tumor population; however, there was no evidence of association between use and quality of life.

Interstitial chemotherapy with biodegradable BCNU (Gliadel) wafers in the treatment of malignant gliomas.

Malignant gliomas represent the majority of primary brain tumors, and the prognosis of the patients afflicted with these tumors has been historically dismal, with almost uniform progressive neurologic impairment and rapid death. Even with multimodal treatment using surgery, focal radiation, and chemotherapy, no major strides were made until recently. The development of interstitial BCNU wafers (carmustine wafers, Gliadel((R))) has led to promising results in the treatment of a selected patients with malignant gliomas, as well as with other intracranial malignancies.BCNU is one of the first systemic chemotherapies which had obtained United States Food and Drug Administration (FDA) approval for the treatment of brain tumors. However, systemic use has been hampered by the modest prolongation of survival and by the prolonged myelosuppression and potentially fatal pulmonary toxicity. The development of interstitial therapies with BCNU represented a great step forward, allowing direct delivery to the tumor bed, with virtually no systemic toxicities. Clinical studies of BCNU wafers have showed good efficacy in both newly diagnosed and recurrent gliomas, as well as a possible therapeutic role in other primary or secondary intracranial malignancies. New studies are currently underway trying to improve the efficacy of the BCNU wafers (Gliadel((R))) by combining them with different systemic chemotherapies. An overview of the current knowledge ranging from the preclinical developments, to the efficacy and safety seen in the clinical trials and in clinical practice following the drug approval to the future avenues of research is therefore timely.
