RESUMEN
The treatment recommendations provided in this manuscript are intended to serve as a knowledge base for clinicians and health personals involved in treating patients with high-grade malignant glioma. In newly diagnosed patients, complete resection or biopsy is required for histological characterization of the tumor, which in turn is essential to decide the treatment strategy. In patients with good or borderline performance score, radiotherapy (RT), and chemotherapy are the preferred management. In patients with poor performance score, RT with best possible supportive care is the mainstay of the management. All patients have to undergo brain magnetic resonance imaging procedure quarterly or half-yearly for 5 years and then on an annual basis. In patients with recurrent malignant glioma, wherever possible re-resection or re-irradiation or chemotherapy can be considered along with supportive and palliative care. High-grade malignant glioma should be managed in a multidisciplinary center with the best of the possible care that is available based on the evidence as discussed in this manuscript.
RESUMEN
Glioblastoma multiforme (GBM), the most common primary brain tumor in adults, is associated with one of the worst 5 year survival rates among all human cancer types. To date, no published data are available for the outcome of this disease in Saudi Arabia. The present study performed a single-center, retrospective cohort study to evaluate the outcome of patients with GBM in Saudi Arabia. The Comprehensive Cancer Center at King Fahad Medical city (Riyadh, Saudi Arabia) was used in the present study. All adult patients (≥18 years) diagnosed with histologically proven GBM between January 2008 and December 2013 were included in the present study. A total of 90 patients were treated during the specified period. Of this, 73 (81%) patients underwent resection and 17 (19%) had biopsy only. The majority of patients (n=88; 98%) received radiotherapy (XRT): 67 (76%) with standard and 21 (24%) with hypo-fractionated dosage. Of the total patients, 65 (72%) received combined modality therapy [standard XRT concurrently with Temozolmide (TMZ)]. The 6 month progression-free survival rate was 43% for all patients and 55% for the combined modality subgroup. The median overall survival (OS) for all patients was 13.7 months. However, the median OS for patients treated with combined modality was 19.7 months. In this single-center retrospective study, the outcomes of patients with GBM were similar to those in previously reported studies. An improved outcome was associated with an improved performance status, absence of residual disease and use of adjuvant TMZ.
