en Volumetric changes in meningioma after six-month follow-up of single session gamma knife radiosurgery: A single-centre study Radiation Biology Radiation Biology تحقيق بديع Original Research <div style="text-align: justify;">Background: Gamma Knife Radiosurgery is a type of radiation therapy that uses a very intense beam of gamma rays that is used in destroying brain tumors like meningiomas without the need to make a surgical interface. The current study aims to assess the impact of Gamma Knife Radiosurgery in meningioma treatment by estimating the changes in meningioma volumes after six months of follow-up. Materials and Methods: 43 participants' data was collected at the Saad Al-Watari Gamma Knife Center in Baghdad, Iraq. The data was gathered from June 2022 to December 2022, and each patient followed after 6 months after the gamma knife surgery. Results: The outcomes show a decrease in meningioma volumes of 83.7% of patients. Only 2.3% of the patients recorded no change in meningioma size. Also, 9.3% of the patients recorded an increase in meningioma size. And finally, the tumor completely disappeared in 4.7% of the patients. Conclusion: Gamma knife treatment is a beneficial option for reducing the meningioma volume. The study demonstrated a significant decrease in tumor size for most patients. Furthermore, a small percentage of patients reported no change or an increase in tumor size, indicating that gamma knife treatment may not be equally effective for all individuals. However, it is essential to mention that two patients reported the complete disappearance of their tumors, suggesting a potential for successful tumor eradication with this treatment.</div> Meningioma, gamma knife, radiosurgery, Iraq, tumor. 1009 1015 http://ijrr.com/browse.php?a_code=A-10-1-1428&slc_lang=en&sid=1 R.S.
