No full textLinear accelerator-based stereotactic radiosurgery in recurrent glioblastoma: A single center experience
No full textBackground/Aim. Management of patients with recurrent glioblastoma (GB) comprises a therapeutic challenge in neurooncology owing to the aggressive nature of the disease with poor local control despite a combined modality treatment. The majority of cases recur within the highdose radiotherapy field limiting the use of conventional techniques for re-irradiation due to potential toxicity. Stereotactic radiosurgery (SRS) offers a viable noninvasive therapeutic option in palliative treatment of recurrent GB as a sophisticated modality with improved setup accuracy allowing the administration of high-dose, precise radiotherapy. The aim of the study was to, we report our experience with single-dose linear accelerator (LINAC) based SRS in the management of patients with recurrent GB. Methods. Between 1998 and 2010 a total of 19 patients with recurrent GB were treated using single-dose LINAC-based SRS. The median age was 47 (23-65) years at primary diagnosis. Karnofsky Performance Score was ≥ 70 for all the patients. The median planning target volume (PTV) was 13 (7-19) cc. The median marginal dose was 16 (10-19) Gy prescribed to the 80%-95% isodose line encompassing the planning target volume. The median follow-up time was 13 (2-59) months. Results. The median survival was 21 months and 9.3 months from the initial GB diagnosis and from SRS, respectively. The median progression-free survival from SRS was 5.7 months. All the patients tolerated radiosurgical treatment well without any Common Toxicity Criteria (CTC) grade > 2 acute side effects. Conclusion. Single-dose LINAC-based SRS is a safe and well- tolerated palliative therapeutic option in the management of patients with recurrent GB

No full textA concise review of immunotherapy for glioblastoma
No full textGlioblastoma (GB) is the most common and aggressive form of primary brain tumors in adults with a universally poor prognosis despite multimodal management including surgery, chemotherapy and radiation therapy. Among the novel therapeutic strategies, immunotherapy deserves particular attention with its potential to evoke biologic response and harness the host immune system. Considerable success achieved for other tumors has elicited great enthusiasm and prompted research on immunotherapy for GB. While the central nervous system has traditionally been thought of as an immune-privileged site, our understanding is being refined with emerging evidence. Several studies have been conducted and more are under way to establish the role of immunotherapy in management of GB. Immunotherapy of GB has yet resulted in mixed success with conflicting research findings, emphasizing the need for extensive study before its integration into routine clinical practice. Although there is a lot of room for improvement, immunotherapy for GB may be feasible and serve as a viable management strategy broadening and strengthening the therapeutic armamentarium to combat this deadly disease. Herein, we present a concise review of immunotherapy for GB
8 Gy single dose radiotherapy for bone metastasis in COVID-19 pandemia period: Review
No full textBone metastases in cancer patients are highly painful and decrease the quality of life for these group of population. Covid-19 pandemia is a global challenging issue that mostly affect the patients with immune suppression or having comorbid diseases older than 65 years old. The palliation and management of bone metastases varies from single dose to several fractionation. The main goal of this article is to decide that short or long term fit for the cancer patients with bone metastasis in the Covid-19 era. We reviewed the topic about the short course and long term radiotherapy in the patients with painful bone metastases via novel literature
