Proton therapy vs Cyberknife

Both CyberKnife and proton beam are types of radiation therapy, however CyberKnife has a number of advantages over proton beam as a cancer treatment. The most modern treatment available is CyberKnife, which uses image-guided robotics to eliminate prostate cancer while protecting surrounding tissue.

Stereotactic body radiation therapy is performed using CyberKnife technology. High doses of radiation are administered to malignancies with sub-millimeter precision during therapy, minimizing damage to healthy tissue nearby. Through the use of particle therapy, proton therapy has the ability to minimize damage to healthy tissue. Doctors determine the exact place in a patient’s body where the proton releases the majority of its energy during proton therapy, maximizing exposure to the treatment region.

What Is Proton Therapy?

Proton Therapy (also known as Proton Beam Therapy) involves the doctor exposing the region of the patient’s body where the tumor is located to proton beams. The cancer cells are subsequently damaged by these charged particles, which eventually kill them and prevent them from replicating.

The Proton beams may, however, have an effect on nearby tissue or organs. Proton Therapy is a sort of particle therapy in which a cyclotron delivers high-energy proton beams to malignancies. Doctors use proton therapy to pinpoint the exact location in a patient’s body where the proton will release the most of its energy, boosting exposure to cancer cells while reducing exposure to healthy tissue. Proton Therapy is usually given in a series of 20-25 treatments, with each session lasting less than 5 minutes. Fatigue is a common side effect that is usually minor and only lasts a few days.

Because proton beam therapy uses lower radiation doses, more treatments are required. Small dosages are given daily over a four to six week period in these therapies, which involve traditional fractionation.

What Is CyberKnife Therapy?

High doses of radiation are administered to the tumor with incredibly accurate, sub-millimeter precision during CyberKnife treatment, which is a common prostate cancer therapy. Any injury to neighboring healthy tissue is largely eliminated or minimized thanks to this precision. Patients will lie on a treatment table while the CyberKnife’s robotic arm glides around their body, delivering high doses of radiation straight to their tumor with precise precision while minimizing exposure to healthy tissue. Depending on the size, form, and location of your tumor, most treatment sessions last 30–60 minutes and require 5 or fewer treatments.

CyberKnife Radiosurgery, also known as stereotactic body radiosurgery, is a type of highly concentrated radiation (SBRT). The CyberKnife equipment, unlike traditional radiation procedures used to treat certain types of cancer, provides a high dosage of radiation in a single or short number of treatments. It’s a painless, non-invasive procedure that, in some situations, could be a viable alternative to open surgery.

With several beams of high-energy radiation, the CyberKnife system uses image-guided robotics to precisely eliminate cancers and other lesions. CyberKnife delivers radiation directly to tumors while keeping healthy surrounding tissue undisturbed, thanks to missile-guided radiation technology that targets tumors with pinpoint accuracy. As a result of missile technology.

Only five treatments are required for CyberKnife therapy. Each treatment portion contains a significantly larger dose than proton therapy. Hypofractionated therapies are what they’re termed.

Prostate Cancer CyberKnife Treatment

For men who have been diagnosed with prostate cancer, there are several viable treatment options available today. The type of cancer, overall health, age, and lifestyle of each man will all play a factor in selecting which choice appears to be the best.

During therapy, the patient lies down on the CyberKnife bed as the treatment machine slowly glides around them. There will be no sensations, and the CyberKnife will not touch you. You can even relax and listen to music or take a nap.

The advantages of using the CyberKnife for radiosurgery significantly outweigh any potential dangers, which are minor.

CyberKnife and Proton Therapy Treatments: What’s the Difference?

CyberKnife is a cutting-edge device that delivers stereotactic body radiation therapy. High doses of radiation are administered to tumors with sub-millimeter precision during therapy, reducing radiation exposure to healthy tissue nearby. The use of particle treatment in proton therapy can help to reduce harm to healthy tissue. Doctors determine the exact place in a patient’s body where the proton releases the majority of its energy during proton therapy, maximizing exposure to the treatment region.

There are numerous more significant distinctions between CyberKnife and Proton Therapy, including the following:

  • Proton Therapy uses a unit of radiation of 1.8 to 2.0 Gy per fraction, whereas CyberKnife uses a unit of radiation of 5 to 20 Gy per fraction.
  • Proton Therapy treatments take 6 to 7 weeks to complete, whereas CyberKnife treatments take 3 to 5 days.
  • Proton Therapy has a 20 to 30 millimeter tissue margin, but CyberKnife only has a 1 to 5 millimeter tissue margin.
  • Proton therapy uses 2-3 radiation beams, whereas CyberKnife uses 100-200+ beams.

Furthermore, Proton Therapy does not provide continual correction for patient movement, but the CyberKnife system’s robotic arm does. This prevents damage to healthy tissue by keeping the radiation beams focused on their target with sub-millimeter accuracy.

This is critical because a person’s body moves naturally, such as when breathing or when the bladder fills with pee (which can move the prostate).  CyberKnife moves in sync with the tumor.

Which Radiation Therapy Should You Select?

If you’ve been diagnosed with prostate cancer or another sort of tumor, CyberKnife and Proton Therapy are two of the various therapy choices to explore. The best treatment for you will, of course, be determined by the location, size, and stage of your tumor.

Consult your doctor to discover which choice best suits your needs. Keep in mind that CyberKnife – also known as the Beam of Life – is a painless, noninvasive treatment that has few, if any, adverse effects and requires little to no recovery time. Some patients report feeling weary afterward, although this goes away fast.

What is Cyberknife’s success rate?

Exceptional survival rates are the product of pinpoint precision.

For low-risk patients, the success rate is 97 percent to 100 percent. In comparison, conventional radiation therapy has a success rate of 92 percent to 94 percent in the past.

What kind of cancer can be treated with proton therapy?

Proton therapy is most typically utilized at MSK to treat tumors of the head and neck, as well as cancers in children. We’re also utilizing it to treat spinal tumors, breast cancer, sarcoma, brain tumors, and prostate cancer more frequently.

What are some of the drawbacks of proton therapy?

Proton treatment may overlook small portions of cancer cells and metastases that are near but outside of the radiation field due to the exact area of radiation delivery.

What is the success rate of proton therapy?

Patients with low to medium risk prostate cancer had a 99 percent success rate, whereas those with high risk prostate cancer had a 76 percent success rate.

What are side effects of CyberKnife?
Some of the most common side effects of CyberKnife include:
  • Fatigue.
  • Nausea.
  • Skin irritation or rash at the site of radiation delivery.
  • Changes in bodily functions like salivary function or urination.
  • Specific problems in the area being treated (such as damage to nearby structures)

What is the duration of a CyberKnife treatment?

Treatments are done as outpatient procedures, with each session lasting 30 to 90 minutes. The number of treatments necessary varies based on the size, location, and shape of the tumor, but usually just one to five daily sessions are needed.

How long has proton therapy been around?

In 1988, the FDA approved proton therapy for use in the United States. Proton treatment has been used for about 60 years, and tens of thousands of patients have been treated, with Medicare and other private insurers covering the costs.

Is proton therapy a better treatment option than chemotherapy?

According to a new study from The University of Texas MD Anderson Cancer Center, concurrent chemotherapy and the specialized radiation treatment proton therapy improves survival for patients with advanced, inoperable stage 3 lung cancer when compared to historical data for standard of care.
