A retrospective analysis was performed on 53 patients with brain malignant astrocytoma and glioblastoma multiforme treated with surgical resection and postoperative radiotherapy in the period between January 1980 and June 1991. There were 13 patients with malignant astrocytoma, 40 patients with glioblastoma multiforme. Survival rates were analyzed according to histologic grade, age, performance status, extent of surgical resection, tumor location, symptom duration, total radiation dose and addition of chemo­therapy after radiation therapy. 5 year actuarial survival rate for malignant astrocytoma was $29.4\%$, for glioblastoma multiforme was $2.8\%$. Histologic grade, age, performance status, total radiation dose were statistitically significant prognostic factors.

A retrospective analysis was performed on 49 patients with astrocytoma or gliobiastoma multiforme of brain who received postoperative radiotherapy in the period between February 1979 and December 1985 Fourteen patients had grade 1 astrocytoma, 11 patients grade II, 14 patients grade III, and 10 patients glioblastoma multiforme. Three year actuarial survival rates were $85.7\%,\;44.0\%\;and\;23.1\%$ for grade I, II, and III astrocytomas, respectively. One and 2 year actuarial survival rates for patients with glioblastoma multiforme were $54.5\%\;and\;27.3\%$, respectively. Histologic grade, age, extent of operation and tumor location were revealed to be prognosticators.

Forty-four patients with brain astrocytoma and glioblastoma were rested with surgical resection and postoperative radiation from January 1980 through May 1987, Four patients were lost to follow up, and in 40 patients survival time was evaluable. Three year actuarial survival rate was $66.7\%$ in Grade I and II astrocytoma, $30\%$ in Grade III, and $20.4\%$ in glioblastoma multiforme patients. The prognostic factors affecting survival rate were histologic grade in all cases, age, and total radiation dose in Grade III and glioblastoma.

We report a case of a 31-year-old woman with glioblastoma multiforme (GBM) in the pineal region with associated leptomeningeal dissemination and lumbar metastasis. The patient presented with severe headache and vomiting. Magnetic resonance imaging (MRI) of the brain showed a heterogeneously enhanced tumor in the pineal region with obstructive hydrocephalus. After an urgent ventricular-peritoneal shunt, she was treated by subtotal resection and chemotherapy concomitant with radiotherapy. Two months after surgery, MRI showed no changes in the residual tumor but leptomeningeal dissemination surrounding the brainstem. One month later, she exhibited severe lumbago and bilateral leg pain. Thoracico-lumbar MRI showed drop like metastasis in the lumbar region. Finally she died five months after the initial diagnosis. Neurosurgeons should pay attention to GBM in the pineal region, not only as an important differential diagnosis among the pineal tumors, but due to the aggressive features of leptomeningeal dissemination and spinal metastasis.

Radiation therapy has been widely applied for cancer treatment. Childhood acute lymphocytic leukemia (ALL), characterized by frequent central nervous system involvement, is a well documented disease for the effect of prophylactic cranio-spinal irradiation. Irradiation, however, acts as an oncogenic factor as a delayed effect and it is rare that glioblastoma multiforme develops during the remission period of ALL. We experienced a pediatric radiation-induced GBM patient which developed during the remission period of ALL, who were primarily treated with chemotherapeutic agents and brain radiation therapy for the prevention of central nervous system (CNS) relapse. Additionally, we reviewed the related literature regarding on the effects of brain irradiation in childhood and on the prognosis of radiation induced GBM.

Primary cerebellar glioblastoma multiforme (GBM) is a rare tumor in adults that accounts for just 1% of all cases of GBM. Due to their rarity, cerebellar GBMs are not yet completely understood about the pathogenesis and the prognosis. Here, we present a case of GBM in a 69-year-old man. Neurologic examination revealed the presence of cerebellar signs. Magnetic resonance imaging (MRI) showed a 4.5${\times}$3.6 cm-sized, ill-defined, heterogeneously enhancing mass in the left cerebellum and two patchy hyperintense lesions in the right cerebellum with minimal enhancement. After operation, glioblastoma was histologically confrimed. Postoperative radiotherapy with concomittent and adjuvant temozolomide chemotherapy was subsequently followed. Here, a case of unusual GBM in the cerebellum is reported with review of literature regarding the pathogenesis, the differential diagnosis and prognosis. There was no evidence of recurrence during postoperative one year. This patient showed a good prognosis in spite of the multiple lesions.

Glioblastoma multiforme (GBM) is the most common primary brain tumor and the most malignant astrocytoma in adults, with rare extra-cranial metastases, especially for subcutaneous metastases. It could be easily misdiagnosed as primary subcutaneous tumor. In this report, we describe a patient with pontine GBM who developed a subcutaneous swelling at the ipsilateral posterior cervical region 8 months after operation, and the pathological and immunocytochemical examination carry the same characteristics as the primary intracranial GBM cells, which defined it as subcutaneous metastasis. GBM with subcutaneous metastasis is extremely rare, and knowledge of a prior intracranial GBM, pathological examinations and immunocytochemical tests with markers typically expressed by GBM are of vital importance for the diagnosis of GBM metastasis. Surgical resection of subcutaneous swelling, followed by chemotherapy and radiotherapy, could be the best strategy of treatment for the patients with GBM subcutaneous metastasis.

Glioblastoma multiforme(GBM) is the most aggressive intracranial tumor and it commonly spreads by direct extension and infiltration into the adjacent brain tissue and along the white matter tract. The metastatic spread of GBM outside of the central nervous system (CNS) is rare. The possible mechanisms of extraneural metastasis of the GBM have been suggested. They include the lymphatic spread, the venous invasion and the direct invasion through dura and bone. We experienced a 46-year-old man who had extraneural metastasis of the G8M on his left neck. The patient was treated with surgery for 5 times, radiotherapy and chemotherapy. He had survived 6 years since first diagnosed. Although the exact mechanism of the extraneural metastasis is not well understood, this present case shows the possibility of extraneural metastasis of the G8M, especially in patients with long survival.

Cystic glioblastoma multiforme (GBM) is a rare disease. Its exact prevalence has not yet been reported. Also, the mechanism of cyst formation remains to be elucidated. We report a case of GBM with a large peripheral cyst. A 43-year-old woman visited our clinic with a 3-month history of severe headache, memory impairment and general weakness. T1-weighted gadolinium-enhanced magnetic resonance (MR) image revealed a midline enhanced solid mass and bilateral symmetric banana-shaped peripheral cysts. A centrally enhanced mass was measured $2{\times}4$ cm in size and both mass and cysts as $7{\times}7$ cm. Both the frontal lobe and the frontal horn were severely compressed inferiorly and posteriorly. We resected a midline solid tumor and cysts via the bilateral interhemispheric transcortical approach. Histopathologic examination revealed GBM. The patient was subsequently treated with fractionated conventional brain radiation therapy, followed by temozolomide chemotherapy. Eighteen months later, there was no tumor recurrence and no neurological deficits were noted. Our patient showed no tumor recurrence and a long survival at a long follow-up.

Objective: The purpose of this report is to present the effects of integrative cancer treatment (ICT) on a patient diagnosed with glioblastoma multiforme (GBM). Methods: A 71-year-old male GBM patient received ICT from May 14 to October 12, 2021 and concurrently received temozolomide and radiotherapy. The effect on symptoms was evaluated using a visual analog scale (VAS), and changes in tumor size were assessed using magnetic resonance imaging. Results: After treatment, the VAS score for nausea decreased from 5 to 1, and the tumor size also reduced. Conclusion: ICT could be effective in treating GBM patients by reducing the size of the tumor as well as alleviating the side effects.
