Which is Better – Surgery vs. Radiation for Prostate Cancer?

For men with localised prostate cancer, current evidence suggests that proton beam therapy does not produce better outcomes than existing radiotherapy techniques. There is also limited evidence to suggest that it results in fewer side effects than radiotherapy. Because standard radiotherapy works just as well as, or better than proton beam therapy, it isnt used to treat prostate cancer in the UK.

Radiotherapy is a highly effective treatment for localised prostate cancer, enabling 98% of men with localised prostate cancer who receive conventional radiotherapy survive for at least 10 years. Men with this stage of the disease can also choose from a series of other treatment options that include active surveillance, radical prostatectomy and brachytherapy.

Unless further clinical trials are carried out to show that proton beam therapy will benefit men with prostate cancer through increased overall survival or the reduction of side effects, Prostate Cancer UK does not actively encourage men to pay for this treatment or seek it abroad.

If you have any concerns about prostate cancer or the treatment options for localised prostate cancer, you can confidentially contact our Specialist Nurses on 0800 074 8383.

Which Treatments Are Best In Keeping Men In Remission

Here is your opportunity to compare prostate cancer treatments. Over 129,000 patients underwent PSA monitoring after treatment to see which treatments were most effective at keeping the cancer in remission. The charts show which treatments are more likely to leave patients Prostate Cancer Free, for how many years. Share this data, talk with your Doctor, or multiple Doctors and make an informed decision. Select the treatment option, that is best for you.

Compare Prostate Cancer Treatments by gathering information about your own Prostate Cancer Diagnosis. Your Doctor will provide three elements that describe your prostate cancer. Your PSA, Stage and Gleason Score. These three elements help you determine your risk group. Find and select your Risk Group in the table below. This will take you to the comparing prostate cancer treatments page, where you can select different prostate cancer treatments on an interactive chart and graphically see their effectiveness over time.

The treatments included in this study are Prostate Surgery or Prostatectomy, , Brachytherapy or Seeds, High Dose Rate Radiation, HDR, External Beam Radiation Therapy or EBRT, Androgen Deprivation Therapy, ADT, or Hormone Treatment, Proton Therapy, High-Intensity Focused Ultrasound, HIFU, Cryotherapy, Cryo and Hypo-Fractionated External Beam Radiation Therapy. For more advanced prostate cancer, treatments are combined to increase effectiveness.

Possible Side Effects Of Ebrt

Some of the side effects from EBRT are the same as those from surgery, while others are different.

Bowel problems: Radiation can irritate the rectum and cause a condition called radiation proctitis. This can lead to diarrhea, sometimes with blood in the stool, and rectal leakage. Most of these problems go away over time, but in rare cases normal bowel function does not return. To help lessen bowel problems, you may be told to follow a special diet during radiation therapy to help limit bowel movement during treatment. Sometimes a balloon-like device or gel is put between the rectum and the prostate before treatment to act like a spacer to lessen the amount of radiation that reaches the rectum.

Urinary problems: Radiation can irritate the bladder and lead to a condition called radiation cystitis. You might need to urinate more often, have a burning sensation while you urinate, and/or find blood in your urine. Urinary problems usually improve over time, but in some men they never go away.

Some men develop urinary incontinence after treatment, which means they cant control their urine or have leakage or dribbling. As described in the surgery section, there are different levels and types of incontinence. Overall, this side effect occurs less often with radiation therapy than after surgery. The risk is low at first, but it goes up each year for several years after treatment.

Proton Vs Photon Radiation

Proton radiation is different from other types of radiation, which rely on photons. Photon radiation comes in three types: intensity-modulated radiation therapy , radioactive seed radiation , and stereotactic body radiation therapy . Sometimes a combination of brachytherapy in conjunction with one of the other types of beam radiation is used.

All types of radiation are effective, resulting in the death of cancer cells. All can potentially cause side effects if the radiation touches adjacent normal organs, such as the bladder, rectum, and urethra.

Stereotactic Body Radiation Therapy

Facet outcomes From Proton therapy For Prostate cancer

This technique uses advanced image guided techniques to deliver large doses of radiation to a precise area, such as the prostate. Because there are large doses of radiation in each dose, the entire course of treatment is given over just a few days.

SBRT is often known by the names of the machines that deliver the radiation, such as Gamma Knife, X-Knife, CyberKnife, and Clinac.

The main advantage of SBRT over IMRT is that the treatment takes less time . The side effects, though, are not better. In fact, some research has shown that some side effects might actually be worse with SBRT than with IMRT.

Proton beam therapy may cause fewer side effects than standard radiotherapy. This is because normal cells are exposed to less radiation. The possible side effects will depend on:

  • the area of your body being treated and what structures are close by
  • the amount of proton beam therapy you have
  • other treatments you are having, such as chemotherapy.

Below are some of the side effects of proton beam therapy. They will not affect everyone who has this treatment. Your cancer doctor, specialist nurse or radiographer will explain any possible side effects to you before you start treatment. It is important to tell them about any side effects you get.

Proton Therapy Treatment For Prostate Cancer Patients

Proton therapy is a form of radiation treatment for cancer patients. Also called proton beam therapy, proton therapy involves focusing proton particles into a beam, which is then delivered to the cancer cells in a non-surgical procedure. The positively charged particles can be controlled to stop at the tumor site, enabling the cancerous tissues to be destroyed with high levels of radiation without causing damage to nearby healthy tissue and vital organs. Proton therapy is considered more precise than other types of radiation therapy. It is also non-surgical, non-invasive, and has minimal side effects. Proton therapy treatment requires little to no recovery time, and the radiation has very little impact on a patients energy level compared to other cancer treatment options.

Proton therapy exhibits higher success rates in prostate cancer patients.

According to a study published by the University of Florida, prostate cancer patients who received proton therapy treatment were found to be free of cancer progression for five years after their treatment. Patients with low to medium risk prostate cancer experienced a success rate of 99%, while those with high risk prostate cancer experienced a success rate of 76%.

What You Need To Know About The Prostate What Is The Success Rate Of Proton Therapy For Prostate Cancer

The main purpose of the prostate is to produce semen, a milky fluid that sperm swims in. During puberty, the body produces semen in a large number of cases, including enlarged prostate. This fluid causes the prostate to swell and cause a number of bladder-related symptoms. This is why the prostate is important to the body. It can be caused by many factors, including infection and inflammation.

A enlarged prostate can also cause blockages in the urethra. A blocked urethra can also damage the kidneys. A patient suffering from an enlargement of the prostate may have pain in his lower abdomen and genitals. If pain is present, a digital rectal examination will reveal hard areas. A doctor may prescribe surgery or perform an endoscopic procedure. If the enlarged prostate is not completely removed, it will shrink.

While the size of an enlarged prostate will influence the extent of urinary symptoms, men may experience a range of urinary symptoms. Some men have minimal or no symptoms at all. Some men will have a very enlarged prostate, whereas others will have a mild enlargement. Generally, the symptoms can stabilize over time. Some men may have an enlarged prostate but not notice it. If they have an enlarged colon, their physician can perform a TURP procedure.

Side Effects Of Radiation Therapy

Compared to earlier radiation methods, these modern techniques reduce the chance of urinary and bowel problems.

With several treatment options available, your doctor will work with you to develop and oversee a treatment plan that precisely addresses your prostate cancer while minimizing the risk to surrounding tissues.

This is why it is important to choose an experienced radiation oncologist who specializes in the management of prostate cancer. High volume centers where practitioners have significant experience and treat large numbers of patients with prostate cancer may be associated with good outcomes and fewer lasting problems related to treatment. The majority of patients who undergo radiation do not have permanent effects on bowel or urinary function, and patients who develop erectile difficulty after these therapies can often be treated successfully with medications such as sildenafil or tadalafil.

Radical Prostatectomy vs. Radiation: How to Compare the Results

Making a decision about prostate cancer treatment is not easy. When considering radiation therapy or radical prostatectomy, one of your top concerns is seeking reassurance that your cancer will be cured following treatment.

Communicate With Your Doctor

The most critical recommendation to reduce your risk is to keep in communication with your doctor. Your case is different from any other, and you deserve personalized treatment. These recommendations should adapt to your case, too. Thus, talk to your doctor and follow recommendations. If your doctor considers it appropriate to screen with PSA testing, talk about the pros and cons with him. And if you need treatment, discuss the benefits and drawbacks of your treatment options. Ask questions and inform yourself about prostate cancer and what to do about it.

Obesity And Dietary Habits

Proton Therapy and Prostate Cancer

High-fat intake, the Western diet, obesity, and sedentary behavior are all associated with a higher incidence of prostate cancer. High calcium intake and a diet high in milk products can increase the risk. After being diagnosed with prostate cancer, calcium can increase the risk of aggressive types. On the other hand, whole milk increases the risk of recurrence of prostate cancer. Obese and overweight men are particularly prone to this increase in recurrence. Another dietary risk factor is vitamin D insufficiency. Meat consumption increases cancer risk, while fish consumption lowers the mortality rate.

Proton Therapy Success Stories

Its one thing to hear about the success rate of proton therapy treatment for prostate cancer. Its another thing to hear the success stories straight from the mouths of survivors.

Wally K.

Wally, an Army pilot, biker, and all around adventurer, was diagnosed with prostate cancer only six weeks after being prescribed testosterone for his anemia.

There are unending volumes in thousands of books that attempt to describe the kaleidoscope of feelings and emotions that follow a diagnosis of metastatic cancer, said Wally in his journal entitled the Proton Chronicles. Im sure that like many, I attempted to rationalize or even justify the situation, but when faced with real mortality, your life and that of your family is forever altered.

After considering surgery and consulting multiple online forums, Wally finally decided on proton therapy to treat his cancer. Over the course of 20 hypofractionated treatments, Knight continued to bike on his favorite trails and play hockey in the local ice rink.

Its really kind of difficult to get your head around the whole situation, said Knight about his proton treatment. This is happening at the cellular level and its absolutely painless.

Earl M.

Earl, a mission pilot and pastor, also received proton therapy after being diagnosed with prostate cancer. Having lived in Alaska for nearly two decades with his wife, Lynn, he chose to seek medical care in other states after receiving his diagnosis.

Another type of prostate issue is chronic prostatitis, or chronic pelvic pain syndrome. This condition causes pain in the lower back and groin area, and may cause urinary retention. Symptoms include leaking and discomfort. In severe cases, a catheter may be required to relieve the symptoms. If the problem is unresponsive to other treatments, your doctor may suggest a surgical procedure. If these do not work, your symptoms could progress and become chronic.

An acute bacterial infection can cause a burning sensation. Inflammation of the prostate can affect the bladder and result in discomfort and other symptoms. This is the most common urinary tract problem in men under 50, and the third most common in men over 65. The symptoms of acute bacterial prostatitis are similar to those of CPPS. Patients may experience a fever or chills as a result of the infection.

A bacterial infection can also lead to prostate issues. Acute bacterial infections can be hard to treat. Some men with a bacterial infection may need to take antibiotics to prevent or treat symptoms. Symptoms of the disease include fever and chills, pain in the lower back and the tip of the penis. Some men may have blood in the urine, frequent urination, and blood in the urine. If you suffer from acute bacterial prostatitis, a medical professional should be able to prescribe you the appropriate treatments to prevent the disease.

Whats The Procedure Like

Since delivering the protons to the cancer cells is the goal of therapy, a lot of time is spent on positioning your body and adjusting the equipment before each session.

Youll have to remain perfectly still while the proton beam is delivered, but it will only take about 1 to 3 minutes. Its noninvasive, and you wont feel anything. Youll be able to leave right away and continue your normal activities.

How Proton Beam Therapy Works

Proton therapy is an advanced form of radiation treatment that uses protons instead of X-rays.

In regular radiation therapy, the beam of energy goes into the body, through the tumor, and out the other side. This exit dose of radiation might affect healthy tissue beyond the tumor. Protons, in contrast, are larger particles than those used in regular radiation. They release more of their energy within the tumor itself. This burst of energy can appear on a graph as what is called the Bragg peak.

After delivering the energy to the tumor, the protons stop: They do not exit the tumor and go into healthy tissue on the other side.

In this way, proton therapy reduces radiation exposure and potential damage to healthy tissue, especially in sensitive areas such as the brain, eyes, spinal cord, heart, major blood vessels and nerves.

Potential Advantages Of Proton Therapy

The relative advantages and disadvantages of proton therapy when compared with photon radiation have evolved over time as the radiation oncology community continues to refine the planning and delivery techniques for both modalities. The results of those comparisons depend on the delivery technique: intensity-modulated proton therapy or double-scattered proton therapy versus static intensity-modulated radiation therapy or volumetric arc photon therapy. The outcomes and costs are further modified by the facility-specific image guidance, motion management, and robust optimization. Nevertheless, some broad conclusions can be drawn concerning the advantages of protons over photons in radiation delivery.

Proton therapy has the potential to improve radiation dose homogeneity, especially within the PTV. Plan homogeneity is desirable with fractionated radiation therapy a homogenous plan avoids delivering hot spots, which are areas of unintentionally elevated dose either within the target volume or in the surrounding organs at risk. Trofimov et al showed that proton therapy reduced the maximum dose and the volume receiving more than 110% of the maximum dose when compared with IMRT among patients treated for prostate cancer.
