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