Background and Objectives: Brain tumor is one of the most common causes of mortality and morbidity. As the result of coordinated progress in diagnostic and therapeutic modalities, management of brain tumors undergo great changes. The main goal of this study, was to determine the frequency of recurrence in different types of brain tumors.
Materials and Methods: In this review, the patients with brain tumor who were operated in Imam Khomeini Hospital in the recent ten years, were demarcated, and recurrent cases were studied, excluding those with incomplete records.
Results: Of 1,112 cases with brain tumor resection, 51 had recurrences and underwent second operation. In recurrent cases, 28 were men and 23 were women. Neuroepithelial tumors consisted of 82% of recurrent cases: meningiomas (10%), pituitary adenomas (4%), and epidermoid tumors (4%). In 21.56% of recurrent cases, the pathologic grade was greater than the first report and disease-free intervals were shorter.
Conclusion: In our review, neuroepithelial tumors included about one half of the brain tumors, as mentioned in other references. Glioblastoma multiform (GBM) and anaplastic astrocytoma (AA) composed 50% of neuroepithelial tumors; in comparison with other references, their frequency was fewer. In contrast to other references, meningiomas had a relatively lower percentage of total number of tumors, but from the other aspects (age, sex predominance, location and clinical course) their characteristics were similar to those in other references.
