First Thousand Cases of Intracranial Radiosurgery Treated with Gamma Knife at a Tertiary Care Hospital in India
Abstract
Purpose We present the profile of first 1,000 cases of intracranial radiosurgery (IRS) treated with Gamma Knife system at a government-funded tertiary care hospital in India. In addition to the information on the indications treated, this study provides an idea of the relevance of the Gamma Knife Radiosurgery (GKRS) for IRS in the fast-changing technological scenario. This study also shows the disease indications for which GKRS was the primary treatment preference.
Materials and Methods Leksell Gamma Knife model 4C was used for GKRS. Leksell G-frame-based stereotactic localization was used for all patients. Axial magnetic resonance imaging scans were used for treatment planning with additional two-dimensional angiography images for patients treated for arteriovenus malformations (AVM). The patient population treated with GKRS at our center mainly comprised of patients referred from across the country.
Results Acoustic schwannoma formed the largest group of patients (27%) followed by meningioma (21%), AVM (18%), pituitary adenoma (16%), brain metastasis (5.3%), trigeminal neuralgia (3%), cavernoma (2.4%), glomus jugulare (1.8%), craniopharyngioma (1.1%) and “others” (5%).
Conclusion The case mix at our center is similar to the overall Indian case mix. However, it is different from the Asian data of 2018 but interestingly similar to the data from Middle East and Africa for 2018. Among the various categories of cranial disorders treated by us, pituitary adenoma tumors had minimum (14/161) and cavernoma tumors had maximum (24/24) proportion of cases managed with GKRS as primary treatment modality.
