Intensity-Modulated Proton Therapy Market to Witness Upward Trend in North America with High Prevalence of Cancer

 

Intensity-Modulated Proton Therapy Market

In the medical field, proton therapy or proton radiography, is a form of radiotherapy, which employs a series of protons, usually paired with an anti-proton beam, to irradiate affected tissue, commonly to cure cancer. When the protons are combined with an electron, or nucleus, they become highly energetic and emit gamma rays. These gamma rays are used to target specific cancerous cells in the treatment of cancer by generating a burst of heat through neutrons and / or electrons. These rays are then absorbed by cancerous tissue to destroy it. This suggests that growth of the intensity-modulated proton therapy market is driven by high incidence of cancer worldwide.

Intensity modulated proton therapy implies the electromagnetic spatial control of well-circumscribed beams of protons of variable energy and intensity. Proton therapy was first used on patients suffering from breast cancer who had no other alternative, apart from surgically removing the whole breast (mastectomy) to remove the cancerous tissue. According to the American Cancer Society, in 2020, around 276,480 new cases of invasive breast cancer will be diagnosed in women and the disease will lead to around 42,170 deaths, in the U.S. The U.S. is thus expected to witness significant growth in the intensity-modulated proton therapy market.

Recently, various studies have assessed and compared the efficacy of intensity modulated proton therapy. When compared with conventional radiotherapy, proton beam therapy has demonstrated significantly reduced toxicity in a randomized controlled trial in patients with esophageal cancer. Moreover, use of intensity modulated proton therapy can help significantly reduce the risk of mini-strokes and heart attacks in the treatment of lung cancer compared to patients who opt for conventional photon-based therapy. Such advantages of intensity modulated proton therapy over other therapies are expected to aid in growth of the intensity-modulated proton therapy market.  

Traditional photon radiation therapy exposes the heart, esophagus, liver, and lung to significant doses of irradiation that can lead to serious side effects. Thus, proton therapy has significant potential in the near future. As of now, only about 2% of radiation therapy is proton therapy, and only 36 proton centers are in operation in the U.S. Thus increase in the number of proton centers is expected to offer lucrative growth opportunities for players in the intensity-modulated proton therapy market.
