Introduction
We treat patients with primary and metastatic brain tumors. Approximately 300 patients were admitted and 202 craniotomies for tumor removal were performed in 2020 including 76 gliomas, 81 brain metastases, 7 primary CNS lymphomas, and 16 meningiomas (Table 1). The site of the craniotomy and the extent of tumor removal were visualized on an intraoperative MRI in real time, contributing to safer and more precise surgery. Intraoperative monitoring with motor- and sensory-evoked potential (MEP and SEP) recording as well as preoperative functional MRI and MR tractography were also used to preserve patient neurological function. Awake surgeries were also performed, particularly for removal of gliomas near the speech center. Patients with malignant brain tumors underwent postoperative radiotherapy and chemotherapy. In order to perform a more effective chemotherapy regimen, molecular biological studies for drug resistance and growth factors, cell kinetic studies on individual tumors and several clinical trials are ongoing.
The Team and What We Do
A weekly conference on treatment of patients with brain tumors is held with doctors of the Department of Radiation Oncology and Pathology, and of the Division of Brain Tumor Translational Research. Usually 10-15 patients are hospitalized and 3 or 4 of them undergo surgical treatment every week. The patients with malignant brain tumors receive postoperative radiotherapy and chemotherapy. Statistical analysis revealed that surgical removal of as much of the tumor as possible yielded better survival rates even for the most malignant glioblastomas, which usually recur soon after the surgery without radiotherapy. Concomitant use of chemotherapy is considered to enhance the anti-tumor effect of radiotherapy. Temozolomide has been given to all malignant glioma patients during radiotherapy and repeated every month for 1 year. R-MPV therapy is administered to the patients with primary CNS lymphoma before radiotherapy.
Table 1. Surgical cases for brain tumors
The decision on the indication for surgery of metastatic brain tumors is not simple. Multiplicity of brain metastasis, the stage of the primary malignancy and the patient performance status should be taken into careful consideration.
Research activities
An analysis of gene expression profiles in malignant gliomas is being carried out in order to determine specific genes that have an influence on the effects of chemotherapy and radiation therapy in cooperation with the Division of Brain Tumor Translational Research, the National Cancer Center Research Institute. The determination of the methylation status of O6-methylguanine-DNA methyltransferase (MGMT) and the mutation of IDH1/2 and TERT are also being carried out to predict the prognosis of the patients with malignant gliomas.
Clinical trials
The Japan Clinical Oncology Group (JCOG)-Brain Tumor Study Group was organized in 2002 and multi-institutional randomized controlled trials are performed. “Randomized phase III study for unresectable WHO Grade II astrocytoma with radiotherapy alone or chemoradiotherapy with temozolomide (JCOG1303)” is ongoing, and so are a phase III randomized study for grade III gliomas (JCOG1016) and some phase III studies for glioblastoma (JCOG1308, JCOG1703 and JCOG1910). These studies, under the surveillance of JCOG, aim to set a standard protocol for treating malignant brain tumor patients. Moreover, a proper methodology for performing randomized studies will be established in the field of neuro-oncology.
An investigator-initiated phase II clinical trial of eribulin targeting TERT in patients with recurrent glioblastomas was completed and a phase II study of temozolomide and metformin for newly-diagnosed glioblastoma is also ongoing under an AMED grant.
Education
Our department plays a pivotal role in the JCOG-Brain Tumor Study Group and the brain tumor registry of Japan, and we conducted many clinical trials and ran the brain tumor registry. We educate many neurosurgeons and oncologists about surgical techniques of awake craniotomy and intraoperative MRI and the effective usage and adverse effects of many chemotherapeutic agents regarding malignant brain tumors.
Future Prospects
Malignant brain tumors, especially glioblastoma, still have the worse prognosis among cancers. We continually strive to defeat these brain cancers through a variety of clinical work and research.
