Introduction:
Glioma is the most common type of primary brain tumor that originates from glial tissues. These types of tumors have a high degree of malignancy and poor prognosis and low survival rates. The evaluation response to treatment is essential to decide whether present treatment is adequate or need for alternative therapy. The aim of this study was to evaluate the response of glioma tumors to the treatment by using of MRI in patients undergoing radiation therapy. Which leads to an assessment of the function of the radiation therapy center in the treatment of this type of tumor.
Materials and Methods:
The 190 patients with glioma tumor who referred to Tohid Radiotherapy Center of Sanandaj were studied during the years of 2009 to 2016. The response rate to radiation was evaluated by using the MRI images with contrast based on the enhanced Gadolinium. Data were analyzed using SPSS 20 software
Results:
The incidence rate of the men was 1.6 times of the women. The most frequent type of tumor was related to GBM tumors by %51.6.  The analysis of MRI images showed that in 161 cases
- approximately 85% - the tumor responded to treatment and the treatment was successful.
Conclusion:
In this group of patients is often due to the sensitivity of the anatomical location of the tumor, there is no possibility of surgery, and they are resistant to chemotherapy because of the blood-brain barrier. Therefore, radiotherapy plays a key role in the treatment of this type of tumor. According to follow-up with MRI- a noninvasive method that can provide information to the anatomical, physiological and molecular- the function of the radiation therapy center acceptable is evaluated for the treatment of these patients.
