@entity1 @entity410 @entity1313 @entity5 @entity4 @entity816 @entity10 @entity204
BACKGROUND: The incidence rate of @entity1313 has increased more than 40% in the past 20 years, especially in adults. We aimed to study the clinical and pathological findings of central nervous system (CNS) @entity5 @entity1 and to evaluate their 5 year survival rates. MATERIALS AND METHODS: The archives of all @entity1 with CNS @entity5 in 6 health care centers in Yazd, Iran, from 2006 to 2013, were studied. @entity1 data were extracted using a checklist which included age, sex, date of reference and diagnosis, date of @entity204 , clinical signs, radiography findings, pathology report, size and location of @entity5 , @entity1 treatment and grade of @entity5 . RESULTS: A total of 306 @entity1 records were studied in the 8 year period. The most prevalent type of @entity5 was @entity816 (n=113, 36.9%). The frequency of almost all @entity5 types was statistically higher in male @entity1 (p=0.025). In most cases surgery with radiotherapy was the treatment of choice (49.3%). The most frequent symptom reported was @entity10 (in 60.8% of @entity1 ) followed by @entity410 (15.7%). Most of the @entity5 were located in the right hemisphere (46.1%) and the frontal and parietal lobe (26% and 12%, respectively). Radiography findings displayed @entity4 with a nonhomogeneous lesion in majority of the @entity1 (87%). The survival fraction of the @entity1 with @entity5 decreased over time (0.807 in the first year and 0.358 at the end of the 5th year). CONCLUSIONS: Astrocytoma was the more common CNS @entity5 with male predominance. Overall survival rates of @entity5 decreased over time and this was in relation with @entity5 grade.
