| Popis: | Objective: The authors aimed to analyze the current epidemiology of high- and low-grade gliomas, follow-up strategies, and prognosis in a national reference center of a developing country. Materials and Methods: Medical records of patients diagnosed with intracranial gliomas from January 2012 to January 2016 were reviewed. Data were classified by age, symptoms, Karnofsky functional scale (KFS), tumor location, extent of resection (EOR), histopathology, hospital stay, Glasgow outcome scale (GOS), adjuvant treatments, overall survival (OS), and mortality. Results: Astrocytomas accounted for 28.2% of the intracranial tumors and 53.5% were male. Headache was the most common symptom, while sensory disturbance was the least frequent. The right cerebral hemisphere was involved in 56.5% of cases and frontal lobe in 31.3%. Gross total resection (GTR) was achieved in 18.1% cases, 35.3% subtotal resection, and 46.4% biopsy. Regarding the astrocytomas, 43.3% were low grade and 56.4% high grade. Low-grade tumors had the highest frequency in the fourth decade of life, while Grade III and IV in the fifth and seventh decades of life, respectively. In high-grade lesions, there was a slight male predominance (~1.4:1). The initial KFS was regularly 80 for low-grade gliomas and 60 for high-grade. By 1-month postdischarge, the score decreased by 10 points. About half of the patients (47.5%) received adjuvant therapy after surgery. From the Glasgow Outcome Scale (GOS), the majority had a form of disability and 30-month OS was above 88% for Grade I-II and 0% for Grade III and IV. Conclusions: Astrocytic tumors were the most frequently noted intra-axial tumors. Age, histological grade, and EOR are important prognostic factors. These results are similar to other reports; however, increased variability was noted when treatment-related factors were considered. Additional studies are necessary to identify the factors related to these treatment results. Highlights: • There are no data describing the basic epidemiology and prognosis of high-grade and low-grade gliomas in Mexico.• Intracranial astrocytomas account for 28.2% tumors in our institution.• Age, histological grade, and EOR are important prognostic factors.• Poor overall survival was achieved in our target population. |
