摘要: Object Low-grade astrocytomas are slow-growing, infiltrative gliomas that over time may progress into more malignant tumors. Various factors have been shown to affect the progression and overall survival including age, performance status, tumor size, extent of resection. However, recently it has suggested histological subtypes (fibrillary, protoplasmic, gemistocytic) impact patient outcome. In this study authors performed a large comparative population-based analysis examine characteristics patients with various WHO Grade II astrocytomas. Methods Patients diagnosed fibrillary, gemistocytic were identified through Surveillance, Epidemiology, End Results (SEER) database. The chi-square test Student t-test used evaluate differences in treatment between astrocytoma subtypes. Kaplan-Meier was assess survival, ...
