Objective: to present our 19 years’ experience in the management of oligodendroglioma brain tumors in adults. Materials and Methods: From a series of 505 adult patients with brain tumors operated on from January 1991 to December 2009, 30 cases (5.9%) were histopathologically diagnosed as oligodendrogliomas. Twenty-six of them achieved a good follow-up. Results: from the 26 patients, the age ranged between 23 and 72 years. Histological diagnosis showed pure oligodendrogliomas in 17 patients and 9 cases of oligoastrocytomas. Ki-67 immunohistochemistry was performed in 23 patients: in 16 positivity was less than or equal to 5% and in 7 it was greater than 5%. Chromosomes 1p and 19q were studied in 12 patients with positive co-deletion in 2 and negative in the other 10. Twenty patients were operated on,3 received radiation therapy and chemotherapy, and 1 brachytherapy with Iodine-125 and two were not operated on (because the diagnosis was incidental, the tumor was small and was located in the motor area). Currently, 19 patients are alive (73%) and 7 died (27%). Mean survival time of the deceased patients was 7 years and 2 months and a median of 5 years and 8 months. Conclusion: it is not possible to make statistical analysis because small number of cases, although total removal seems to be the best treatment option, due to our small series of cases, we hope randomized double-blinded future studies will clear up the best choice of diagnosis and treatment. |
