What To Expect With Prostate Cancer Radiation Therapy

CyberKnife Treatment For Prostate Cancer What are My Options?

With each of these treatments, there are often side effects that can include short-term complications including urinary and bowel problems. However, depending on the treatment, side effects can be minimized.

The Risk of Long-Term Complications with Radiation Therapy is Low Less Than 5% According to the Prostate Cancer Foundation.

The risk of cancer recurring after receiving radiation treatment for prostate cancer is less than 1%.

With more precise treatments, side effects are lower than ever, but you must make sure the treatment center you choose has highly-skilled radiation oncologists, physicists, and radiation therapists like those at the CyberKnife Center of Miami.

Protecting Healthy Tissue Protecting Quality Of Life

Despite the higher dose rate associated with SBRT, multiple studies have validated that there are no worse side effects with CyberKnife SBRT than with traditional radiation.1 Unlike any other radiation treatment, the CyberKnife System continually tracks the target and automatically adapts the radiation beam for movement of the prostate in real-time throughout the entire treatment session. With this automatic motion tracking and synchronization, the CyberKnife System enhances your treatment teams ability to maximize the radiation dose delivered to the target, while minimizing dose to surrounding healthy tissues to reduce negative side-effects on urinary, bowel, and sexual function that can impact a patients quality of life. The majority of patients can continue normal activity during and immediately after treatment.

You can eat various types of other meats. I suggest to eat chicken,turkey,& lots of fish. I buy all natural chicken, all natural turkey,& wild caught & fresh fish.

I eat as much as I want of these type meats. I never thought Id like grounded turkey. I can honestly say that a turkey burger is much better than any hamburger I ever ate. I wouldnt have thought so but it honestly is a better taste & health option.

I eat all the chicken I want. I suggest you to bake it & not fry it in oils. If you do fry then please use Extra Virgin Olive Oil. I add Mrs. Dash seasonings to all my meats. This is an all natural source for seasonings. There are many different flavors by Mrs Dash.

I also eat all the fish I want. I suggest eating salmon,flounder,tilapia,pollack,catfish,trout,& many other fish. Try to eat the oily type fish. Salmon & trout are two of the top oily fish on the market. Here too I suggest baking instead of frying.

Now, I want to move onto another area of the diet. I will be discussing the importance 0f fruits & vegetables. Fruits was definitely a foreign word to me before prostate problems. I did eat limited amounts of veggies but not enough. I made that change as well in my life. Its very important to eat fruits & veggies to have a healthy diet.

Heres The Breakdown Of Types Of Ebrt:

Stereotactic Body Radiation Therapy : This therapy uses advanced image-guided techniques to deliver larger doses of radiation to a very precise area. Since there are larger doses of radiation, treatment lasts only a few days as opposed to longer treatment courses with other forms of radiation. This therapy is less likely to damage surrounding healthy tissue.

The experts at the CyberKnife Center of Miami use a form of SBRT called CyberKnife to kill prostate cancer. Its not a knife at all, but a powerful state-of-the-art form of external radiation.

Three-Dimensional Conformal Radiation Therapy :Computers map the prostate then aim radiation at the cancer. The treatment is give in lower doses of a longer course of treatment. Up to 45 days 5 days a week. This therapy is less likely to damage surrounding tissues as well.

Intensity Modulated Radiation Therapy : This is an advanced form of 3D-CRT. It also is given in up to 45 days of treatment. The difference is that it uses special mechanical blocking systems to help spare normal tissue.

Proton Beam Radiation Therapy:This therapy focuses beams of protons instead of x-rays on the cancer. This therapy allows for more radiation to hit the prostate while doing less damage to surrounding tissues.

With each of these treatments, there are side effects, which can include short-term complications including urinary and bowel irritation.

Role In Treating Lesions/tumours Of The Spine

Columbus CyberKnife Announces Milestones in Prostate Cancer Treatment

Nearly 9 studies2125 have evaluated the role of Cyberknife in spinal lesions. Conclusions are hard to derive as the subjects are highly hetereogenous in the type of spinal lesions involved . As a primary treatment Cyberknife can achieve a local control of nearly 90% in patients with a median follow up of 18 months. Radicular pain has been relieved in 2585% of patients and neurological deficits improved to a lesser degree. Several large studies have analyzed the planning constraints in the treatment of spinal lesions. They have inferred that a constraint of 10 Gy to less than 10% of contoured spinal cord is safe. Currently available data suggest that a higher maximal dose of 20 Gy is also safe and feasible. This makes a very good option for patients with previously irradiated spine and metastatic disease.

Are There Any Side Effects

Thanks to its ability to work precisely, the CyberKnife for prostate cancer is actually safer than other options. The accuracy helps in preventing sexual, urinary, or bowel complications. But it is possible for radiation treatments to come with a few minor and temporary side effects. These include, however, not limited to:

  • Constipation
  • Blood in stool

Why Does Motion Synchronization Matter

Being able to precisely and accurately deliver radiation makes a difference in terms of controlling cancer and reducing the risk of side effects. But tumor or patient movement as a result of normal body functions, including regular breathing, filling of the bladder, or gas in the bowel can shift the tumor by a centimeter or more, which can make it challenging to accurately target the radiation and result in under- or over-dosing of the tumor. Too much radiation may increase the risk of side effects while too little may reduce the effectiveness of the treatment. Tracking the tumors movement and synchronizing the delivery of radiation with that movement helps to maximize treatment effectiveness, while minimizing dose to surrounding tissues, which can help reduce the incidence of side effects.

CyberKnife Treatment for Prostate Cancer What to Expect

Its not a question of which type of radiation therapy is best in general, but rather which therapy is best for the patients specific disease and quality-of-life concerns. We want to use the most tailored, pinpointed radiation to treat the prostate tumor effectively while minimizing side effects. This can depend on the tumors size and stage as well as other patient characteristics and even a patients individual preferences.

Cyberknife Radiation Treatment For Prostate Cancer:

Options for management of localized prostate cancer range from active surveillance/watchful waiting to surgery and various forms of radiation, with or without hormone therapy. The most appropriate option depends on the extent and aggressiveness of the cancer as well as patient preference.

National guidelines recommend CyberKnife stereotactic body radiation therapy as an appropriate treatment option for men with low or intermediate risk disease. In addition, selected patients with Gleason 8 cancers may be candidates for CyberKnife radiation treatment for prostate cancer.

Low Risk Disease is defined as T1-2a, Gleason 6 cancer, and PSA < 10.

Intermediate Risk Disease is defined as T2c or less, and/or Gleason 7 cancer, and/or PSA 10-20.

CyberKnife radiation for prostate cancer has been successfully performed on tens of thousands of men over the past 15 years. No longer considered experimental, numerous studies have demonstrated excellent long-term cancer control with minimal side effects or risks. The CyberKnife system is considered the gold standard for performing prostate SBRT as compared to other radiation machines. Our center is one of the most experienced CyberKnife centers in the Northeast in treating prostate cancer. We have successfully treated hundreds of men with CyberKnife SBRT since 2006.

The Cyberknife Treatment Procedure Steps

At the Alaska CyberKnife Center at Providence Cancer Center, our team of radiation oncology specialists will work with the rest of your medical team to develop the best plan for your CyberKnife prostate cancer treatment. The basic treatment steps include:

  • Imaging Your clinicians will use a high-resolution CT scanner to determine the size, shape and location of your tumor. This imaging data is then digitally transferred to the CyberKnife Systems software, where treatment planning begins.
  • Treatment planning Your board-certified physician will use the CyberKnife software to generate your unique treatment plan, which prescribes the radiation dose directly to your tumor, protecting healthy surrounding tissues.
  • Fiducial placement Once the plan has been developed, you are ready to undergo treatment. The process of prostate cancer radiation treatment with the CyberKnife System begins by placing the fiducial markers into the prostate. These tiny golden seeds help the CyberKnife System locate your tumor and track its movements.
  • Custom Cradle Next, your treatment team creates your treatment cradle, which is made from soft material that conforms to your shape. You will lie in the treatment cradle during each treatment session at our comfortable Anchorage cancer treatment center. It will help you maintain your physical position from one treatment to the next and ensure your comfort during treatments.

    What Is Cyberknife Cancer Treatment

    CyberKnife radiosurgery, also called stereotactic radiosurgery, is a form of radiation therapy that delivers high-dose radiation on an exact area of the body. CyberKnife radiosurgery targets and treats tumors in the body with very minimal damage to surrounding healthy tissue, which is the primary cause of cancer treatment side effects. Because of this, it is an excellent alternative to traditional cancer treatments, such as radiation, chemotherapy and surgery.

    CyberKnife delivers higher doses of radiation than typical treatments, thereby requiring fewer treatments in a smaller time period. Most patients will undergo 1 to 5 treatments, with each treatment delivered in an as little as 25 minutes.

    CyberKnife treatment attacks cancer using technology to accurately target a tumor down to about 4/1000ths of an inch.

    Radiotherapy, and CyberKnife in particular, is the best or the only option for patients who are at a high risk from traditional cancer surgery. CyberKnife therapy can be an alternative for slowing the growth of small, deep brain tumors that can be difficult to reach by surgery.

    How Cyberknife Treatment Is Performed

    Before treatment, the CyberKnife surgeon conducts a variety of scans on the patient to map the tumor 3 dimensionally. During therapy, the patient lies under a robotic device, computer-controlled to move around the patient and focus radiation precisely on the area of treatment.

    The radiation dosage is determined by the properties of the individual tumor, such as its location, size, shape and density. The tumor shape is precisely marked, allowing CyberKnife to determine its position within just 1 millimeter, even if the patient moves or the tumors position changes slightly. Most tumors tend to shift during various treatments due to changes in their size and shape. CyberKnife compensates for this with continual image guidance throughout treatment.

    CyberKnifes 360-degree movement allows it to deliver radiation beams at hundreds of different angles, precisely targeting the tumor. This reduces the amount of healthy tissue that is damaged during treatment, dramatically reducing side effects from treatment.

    CyberKnife patients generally can go home immediately. Doctors usually monitor a patients progress via scans weeks or months after treatment, depending upon the condition being treated.
