[A survey of neurosurgeons' policies and attitudes regarding the disclosure of a diagnosis of glioma and the decision to pursue end-of-life care in glioma patients].

Objectives: Patients with malignant gliomas have an even worse prognosis than other cancer patients, and they sometimes undergo surgery and chemo-radiotherapy without having been informed of the nature of the disease and its prognosis in Japan. Often, patients with glioblastoma are only told that they have a brain tumor, although other family members are told of the real diagnosis and prognosis. Since patients with glioblastoma, often experience a rapid deterioration in their condition, they usually do not have enough time to seek a second opinion regarding their disease. We surveyed neurosurgeons in Japan with regard to their policies and attitudes concerning the disclosure of a diagnosis of glioma and their thoughts on the end-of-life care of glioma patients.
Methods: A survey was performed in November, 2007. A questionnaire was sent by e-mail to 259 participants who planned to attend the 25th Brain Tumor Conference in Japan.
Results: One hundred and thirty-two participants (51%) returned the questionnaire. Almost all the respondents were neurosurgeons specializing in malignant brain tumors. The percentages of respondents who informed their patients of a diagnosis of grade 2 astrocytoma, grade 3 or grade 4 glioblastoma were 73%, 57% and 37%, respectively. More than 80% of all glioblastoma patients were only told that they had a malignant brain tumor. Sixty-eight percent of the doctors told the family members, but not the patients, of the real diagnosis. The neurosurgeons' policies and attitudes toward end-of-life care for patients with gliomas were also analyzed.
Conclusions: Most neurosurgeons have difficulty disclosing a diagnosis of glioma and providing end-of-life care. This survey will help to develop guidelines regarding disclosure and the decision to pursue end-of-life care for patients with gliomas. (Received : March 19, 2009, Accepted : June 8, 2009)
