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®) 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®) 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

Improving Attitudes and Perceptions About End-of-Life Nursing on a Hospital-Based Palliative Care Unit.

Nurses play an integral role in high-quality patient care. Thus, their skills in providing end-of-life care should be assessed and continually enhanced. Education intended to improve end-of-life skills must address the affective/emotional component of nursing care. Evidence demonstrates that emotional engagement and resilience among health care providers are correlated with improved quality outcomes and, conversely, that burnout and stress negatively affect patient safety. Addressing the emotional needs of health care providers is critical to improving quality throughout the health care system. An evidence-based workshop was implemented among direct care staff on a hospital-based palliative care unit, with the goal of fostering emotional engagement to improve staff perceptions and attitudes about caring for patients at or near the end of life. Although perceptions about quality of death were not affected by this intervention, there was a significant improvement in attitudes about end-of-life nursing care. Qualitative feedback also reflected appreciation for small group discussions and opportunities to debrief with peers away from the unit. This intervention reflected the value of emotional engagement in educational efforts to improve end-of-life nursing care
