Gamma Knife – Targeted Brain Tumor Treatment
Gamma knife is an outpatient procedure that allows the patient to travel back home the same day of treatment. Gamma knife is a highly focused radiation therapy for brain or spinal cancer involving a single treatment high-dose radiation therapy. Cyberknife on the other hand, which can treat cancer anywhere in the body, involves one to five radiation treatment capability. Gamma knife therapy is considered to be much safer than the open-skull surgeries owing to these factors. The global gamma knife market is expected to grow gradually with increase in awareness. There are more than 300 gamma knife centers worldwide at present, which are estimated to treat nearly 60,000 patients every year. However, there still exists a high demand-supply gap in the countries in pacific region, and Africa continent. China, India, Thailand, South Korea, and Japan are leading countries in terms of the number of gamma knife centers. The gamma knife market is therefore considerable in this region, however behind North America and Europe where the number of gamma knife centers exists far more than Asia.
The global gamma knife market was valued at US$ 174.4 million in 2016 and is expected to expand at a CAGR of 7.7% during the forecast period (2017 – 2025).

Non-invasive precision therapy to favor the growth of global gamma knife market
Gamma knife radiotherapy involves convergence of 201 beams that can treat the tumor cell leaving precisely leaving the surrounding healthy cells undamaged. Utilizing the pre-operative diagnostic images form CT/MRI scan, the instrument provides highly accurate irradiation at the tumor site. This is a major factor that drives the usage of gamma knife radiotherapy in treating brain tumors. Application of this procedure is increasing further in trigeminal neuralgia, and arteriovenous malformations. However, gamma knife is limited to 190 positions to reach the tumor cells.
Alternative treatment options include Cyberknife, LINAC radiosurgery, conventional brain surgery, proton therapy, and modified linear accelerators. Gamma knife is the most researched and established radiosurgery. There are over 2,500 published studies for gamma knife.
Potential target population for the global gamma knife market
Considering the current number of patients being treated i.e. 60,000, there exists a major growth potential for gamma knife market. Installation of gamma knife equipment at various locations to improve accessibility would propel the gamma knife market growth in near future.
Chronic neurological disorders such as metastatic brain tumors, trigeminal neuralgia, and arteriovenous malformations are complex to treat. Standard brain surgery and radiation therapy can damage healthy tissues and cause various side effects. Moreover, these treatment methods involve in-hospital post treatment care. Gamma knife, which has been introduced decades ago, is one of the most effective non-invasive technologies that is steadily gaining traction in the treatment of tumors. Gamma knife surgery represents a major advancement in brain surgery, with a one-day treatment procedure. Patients can go home the same day after treatment with gamma knife.
There are over 2,500 published studies for gamma knife, far more than that for alternative treatment options for brain tumors. Abnormalities measuring less than 1 inch in diameter can be treated with gamma knife. Leksell Gamma Knife is the among most efficient gamma knife devices in the market. The device radiates 201 beams that converge at the lesion point, thus destroying only the affected or target tissue. The device can be programmed to for multiple sessions.
Increasing awareness about the high affectivity of these products and their lowering cost will increase the adoption of this device in the near future. There are a number of centers located globally for gamma knife treatment. Increase in healthcare investments in China, India, Brazil, and other emerging economies would be a major contributing factor towards increase in revenues of the global gamma knife market.
