OBJECTIVE: Temozolomide is a novel oral alkylating agent, which has been reported to be effective in treating patients with recurrent malignant gliomas. This study report an analysis of the activity and toxicity of temozolomide as second-line therapy for patients with recurrent and progressive malignant gliomas after surgery and standard radiation therapy with or without chemotherapy. METHODS: Twenty patients with malignant gliomas of which thirteen(65%) had glioblastoma multiforme(GBM), five(25%) with anaplastic astrocytoma(AA), and two(10%) with anaplastic oligodendroglioma(AO) were enrolled in this study. They had been treated in our institution since July, 2000 and had been previously irradiated with or without chemotherapy. For the patients with recurrent and progressive disease, temozolomide(150-200mg/m2/d x5 days) was administered every 28 days until the progression of the tumor or toxicity developed. RESULTS: The median number of treatment cycles was 3(total 86). Of the 20 patients, 2(10%) achieved a complete response(CR), 5(25%) achieved a partial response(PR), 5(25%) had stable disease(SD), and 8(40%) had progressive disease(PD). One patient achieved a CR, 3 patients achieved a PR, 2 patients had SD and 7 patients had PD in GBM, and 1 patient achieved a CR, 2 patients achieved a PR, 3 patients had SD, 1 patient had PD in the non-GBM patients. Median progression free survival(PFS) was 8 weeks in GBM and 22 weeks in the non-GBM patients. No hematological toxicity greater than grade 2 was observed, and hepatotoxicity of grade 2 was encountered in 1(5%) patient. CONCLUSION: Temozolomide demonstrate moderate activity in recurrent and progressive malignant brain tumors, and the response rate and PFS were better in the non-GBM tumors than in the GBM tumors. The treatment is well tolerated without any serious toxicity.

A rare case of microgliomatosis(reticulum cell sarcoma) of the brain is reported. The tumor was located in the left parietal lobe and the right cerebellar hemisphere and the vermis. V-P Shunt was performed and left parietal craniotomy was done for removal of tumor. The patient received radiation therapy and chemotherapy for brain tumor with a good result Histogenesis and therapy of the microgliomatosis are briefly discussed.

The authors have studied six patients with histologically proven primary malignant lymphoma of the brain which is still a rare primary brain tumor. The clinical, radiological and pathological findings with results of the treatment are presented. All cases showed a good response to radiation therapy. Therefore, the early diagnosis by computerized tomography scan followed by biopsy or excision is considered to be very important for the BEST results in the treatment. Related reports are discussed briefly.

Brain metastases are common in lung cancer patients, indicating a poor prognosis and short survival time. In recent years, with the development of surgery, radiotherapy and medical therapy, the survival time of lung cancer patients with brain metastases has been prolonged owing to more and more treatment options. In order to reflect the progress in the treatment worldwide timely, and further improve the level of standardized treatment of lung cancer with brain metastases in China, Chinese Association for Clinical Oncologists and Medical Oncology Branch of Chinese International Exchange and Promotion Association for Medical and Healthcare organized experts to formulate "Clinical practice guideline for brain metastases of lung cancer in China (2021 version)" .

In the treatment of the intracranial gliomas surgical intervention is recommended as the standard procedure which should be performed in all cases when the tumor is accessible. While surgery will not bring about a cure and clearly, radiation therapy and chemotherapy have made a significant impact of long-term survival in the treatment of the malignant gliomas, nevertheless surgery still remains the single most effective method for achieving a rapid reduction of tumor burden reducing increased intracranial pressure and provides a tissue diagnosis. Following surgery, the other antitumor programs have the best chance of achieving a significant increment of tumor cell kill, therefore, surgery has a distinct role to play in the multidisciplinable approach to the treatment of these highly aggressive malignant tumors. It is very unlikely that future advances will obviate the necessity for conventional surgery in the treatment of benign gliomas. The surgical management of gliomas with major emphasis on malignant ones is presented including the pathophysiology, radiological diagnosis, aim of surgery, surgical procedure and some different possibility of surgical treatment. Prospective future development of surgical treatment of brain tumor is also considered.

This report presents an analysis of 25 Korean patients with metastatic brain tumor seen at Seoul National University Hospital from 1968 to 1977. In the same period there were 386 cases of brain tumors, so about 6.5% of total brain tumors was metastatic. The results are as following ; 1) The sexes were represented almost equally, with 12 males and 13 females. In 21 cases(84%) the disease occurred between the ages of 31-60 years. 2) The most frequent site of primary malignancy was lung and the nexts were gastroin testinal tract, breast, liver and chorioepithelium in order. 3) About two-thirds of metastatic brain tumors were located in the middle cerebral artery supplying areas. 4) Averages interval between the clinical onset of primary and secondary growth was short inliver and lung cancer, and long in breast and stomach cancer. 5) In cases which can be treated surgically chemotherapy and radiation seemed to improved the prognosis.

The overall goal of our research projects is to develop effective immunotherapeutic regimens, particularly combining vaccine and gene therapy/ cell therapy strategies. For the development of clinically effective immunotherapy for brain cancers, the following issues are considered to be particularly important: 1) Induction of effective immune responses against tumors (afferent arm of the immune response), 2) Delivery of immune effector cells to the target tumor sites and maintaining the activity of the effector cells (efferent arm), 3) For specific and safe immunotherapy, specific brain tumor rejection antigens have to be identified, 4) Feasibility, safety and efficacy need to be tested in a series of clinical trials. The following presentation summarizes my research projects and demonstrates how each plan will fit in the whole schema of designing successful immunotherapeutic strategies for brain cancers. In this presentation, I would like to focus on our clinical and basic studies related to the vaccine strategies for patients with glioma, and modulation of tumor-microenvironment using bone-marrow derived stroma cells as vehicles for cytokine- gene delivery.

Despite current advances in multimodality therapies, such as surgery, radiotherapy, and chemotherapy, the outcome for patients with high-grade glioma remains fatal. Understanding how glioma cells resist various therapies may provide opportunities for developing new therapies. Accumulating evidence suggests that the main obstacle for successfully treating high-grade glioma is the existence of brain tumor stem cells (BTSCs), which share a number of cellular properties with adult stem cells, such as self-renewal and multipotent differentiation capabilities. Owing to their resistance to standard therapy coupled with their infiltrative nature, BTSCs are a primary cause of tumor recurrence post-therapy. Therefore, BTSCs are thought to be the main glioma cells representing a novel therapeutic target and should be eliminated to obtain successful treatment outcomes.

Despite advances in neurosurgery, radiation, and chemotherapy, the prognosis of patients with malignant brain tumors still remains grim. Considerable efforts have been made to develop new therapeutic strategies for malignant brain tumors. One of the promising new therapies for brain tumors is an intervention at molecular level, and several molecular approaches have been shown to have in vitro and in vivo activities. These include the use of retroviral vectors, herpes simplex viruses, adenoviral vectors in gene transfer, and antisense vectors and oligonucleotides. Preclinical studies of retroviral vector have already been extended to clinical trials, clearly demonstrating the clinical potential of these molecular therapies. Here, I discuss the current status of molecular therapy for brain tumors together with future directions for its development.
