Prostate Cancer: Surgery vs. Radiation Treatment

“At Yale Medicine, we take a number of approaches that set our care apart,” says Dr. Yu. “First, we have a large physics staff that is essential to designing and verifying our radiation treatment plans. Second, we make it a point to evaluate new radiation technologies critically. We dont hold onto old approaches, but neither do we jump on the latest trends without seriously assessing what they will contribute.”

Third, adds Dr. Yu, we are running a growing prostate cancer research program and Yale Medicine is home to leading voices in urology, medical oncology and radiation oncology. “Were also on the forefront of MRI-guided prostate biopsy,” he says, “and, our bedrock is Yales multidisciplinary prostate cancer program, which brings together multiple insights collaboratively.”

Brachytherapy For Prostate Cancer

Brachytherapy is a form of internal radiation therapy. With this type of therapy, radiation is delivered to the prostate tumor inside the body via a catheter or another implantable device.

High-dose rate brachytherapy uses radioactive Iridium-192 to deliver high doses of radiation to the prostate tumor. Treatments are short, sometimes requiring as few as five sessions. Brachytherapy radiation more tightly surrounds the tissues were targeting, which may help spare normal tissues.

Common Thoughts And Feelings

You may feel all sorts of things after you finish treatment. Some men are relieved and feel ready to put the cancer behind them and get back to normal life. But others find it difficult to move on. Adjusting to life after cancer can take time.

For some men, the emotional impact of what they have been through only hits them after they have finished treatment. You might feel angry for example, angry at what you have been through, or about the side effects of treatment. Or you might feel sad or worried about the future.

Follow-up appointments can also cause different emotions. You might find it reassuring to see the doctor or nurse, or you may find it stressful, particularly in the few days before your appointments.

Worries about your cancer coming back

You may worry about your cancer coming back. This is natural, and will often improve with time. There are things you can do to help manage your concerns, such as finding ways to reduce stress. Breathing exercises and listening to music can help you relax and manage stress. Some people find that it helps to share what theyre thinking with somebody else, like a friend. If you are still struggling, you can get help for stress or anxiety on the NHS you can refer yourself directly to a psychological therapies service or ask your GP.

If youre worried about your PSA level or have any new symptoms, speak to your doctor or nurse. If your cancer does come back, you’ll be offered further treatment.

How Can I Reduce Skin Reactions

  • Gently cleanse the treated area using lukewarm water and a mild soap such as Ivory, Dove, Neutrogena, Basis, Castile, or Aveeno Oatmeal Soap. Do not rub. Pat your skin dry with a soft towel or use a hair dryer on a cool setting.
  • Try not to scratch or rub the treated area.
  • Do not apply any ointment, cream, lotion, or powder to the treated area unless your radiation oncologist or nurse has prescribed it.
  • Do not wear tight-fitting clothing or clothes made from harsh fabrics such as wool or corduroy. These fabrics can irritate the skin. Instead, choose clothes made from natural fibers such as cotton.
  • Do not apply medical tape or bandages to the treated area.
  • Do not expose the treated area to extreme heat or cold. Avoid using an electric heating pad, hot water bottle, or ice pack.
  • Do not expose the treated area to direct sunlight, as sun exposure may intensify your skin reaction and lead to severe sunburn. Choose a sunscreen of SPF 30 or higher. Protect the treated area from direct sunlight even after your course of treatment is over.

What are the most common earliest symptoms of prostate ...

However, if youre okay with waiting for the PSA nadir, and if you dont mind getting treatment over the course of a few weeks instead of in one operation, then radiation may be ideal for you.

What are my options?

Conventional external-beam radiation therapy is given in little doses, a few minutes a day, five days a week, for seven or eight weeks. These small doses minimize the injury risk for the healthy tissue near the tumor. Scientists measure radiation in units called Gy . Most men get a minimum total dose of 75.6 Gy, but could get as much as 81 Gy this works out to 2 Gy or less per day.

The treatment itself is painless just like getting an x-ray at the dentists office. But one big challenge with getting repeated treatments is making sure youre always in the exact same position, so the radiation can hit the target the way its supposed to. Thus, you will be custom-fitted with your own pelvic immobilization device, which will not only keep you from fidgeting, but will make sure youre not slightly higher and to the right on the table one day, and slightly lower and to the left the next.

When you get fitted for your device, you will have a CT scan, so doctors can get a 3D look at your prostate. Then, when you get the radiation, you wont just get it from one side, but from multiple directions, and each beam of radiation will be individually shaped to target the cancer and a 5- to 10-millimeter margin of healthy tissue around the prostate.

Guided by advanced imaging techniques, SBRT delivers large doses of radiation over a short period of time to a precise area. SBRT is commonly referred to by the names of the machines used to deliver the radiation. SBRT can offer some patients with localized prostate cancer the convenience of fewer treatments while maintaining treatment effectiveness and safety. SBRT may also be used to treat metastases for some patients to reduce tumor mass and potentially enhance survival.

Its so common that it sometimes doesnt go diagnosed until autopsies are performed, though that doesnt mean the cancer is the cause of death. On the contrary, the overall prognosis for men diagnosed with prostate cancer is as positive as you can get when talking about the dreaded c word. The five-year survival rates for the disease are close to 100 percent, especially when talking about prostate cancer that is caught early on in the processbefore it spreads.

Recovery from cancer is not always possible. If the cancer cannot be cured or controlled, the disease may be called advanced or terminal.

This diagnosis is stressful, and for many people, advanced cancer may be difficult to discuss. However, it is important to have open and honest conversations with your health care team to express your feelings, preferences, and concerns. The health care team has special skills, experience, and knowledge to support patients and their families and is there to help. Making sure a person is physically comfortable, free from pain, and emotionally supported is extremely important.

People who have advanced cancer and who are expected to live less than 6 months may want to consider hospice care. Hospice care is designed to provide the best possible quality of life for people who are near the end of life. You and your family are encouraged to talk with the health care team about hospice care options, which include hospice care at home, a special hospice center, or other health care locations. Nursing care and special equipment, including a hospital bed, can make staying at home a workable option for many families. Learn more about advanced cancer care planning.

Are There Any Long

Long-term risks are slight, but do exist. Its rare but possible that a patient will suffer worsening urinary and rectal function, and there is always a risk of radiation causing cancer.

“Because there are some risks, albeit small ones, we do not treat a patient unless we believe that we can have a real impact on his survival,” says Dr. Yu. For a patient with a very slow-growing cancer, we typically monitor instead of advising immediate treatment.”

Hormonal Therapy For Aggressive Prostate Cancer: How Long Is Enough

  • By Charlie Schmidt, Editor, Harvard Medical School Annual Report on Prostate Diseases

Men weighing treatment options for intermediate- or high-risk cancer that is still localized to the prostate can face a tricky question. A standard approach in these cases is to give radiation to the prostate along with drugs that block testosterone, a hormone that makes the cancer cells grow faster. For how long should this hormone therapy last? Thats not entirely clear. The drugs have side effects, such as fatigue, impotence, and a loss of muscle mass. But radiation doesnt control prostate cancer effectively without them. Doctors therefore aim to give hormone therapy only for as long as it takes to help their patients, without causing any undue harm.

Now, newly published results from a phase 3 clinical trial are providing some needed guidance.

Bowel And Bladder Problems

Radiation therapy for prostate cancer can irritate the bowel, the bladder, or both.

A person can develop:

Radiation proctitis: Symptoms include diarrhea and blood in the stool.

Radiation cystitis: Symptoms include a need to urinate more often, a burning sensation when urinating, and blood in the urine.

Bladder problems may improve after treatment, but they may not go away completely.

Prostatectomy Vs Radiation What To Choose

What You Need to Know About Prostate Cancer

In general, there are 2 major treatment options for prostate cancer. On one side you have the surgery, on the other side, I call it The whole other bucket of treatments that include: proton beam, cyberknife that is very advertised that goes in the bucket of radiation. Seed implant, external beam radiation, HIFU, Cryotherapy all of them go into one bucket and surgery goes in the other bucket and you are right at the fork. So, what is the difference, what are the pros and cons, and what are some of the advantages?

When it comes to surgery, we are removing the entire prostate, we are removing the sample lymph nodes and the seminal vesicles. You will be able to get a very accurate stage and answers to these questions:

  • How much cancer do I have?
  • What type of cancer is it?
  • Where is it located?

That stage comes with surgery. Radiation wont give you that kind of answer.

The other advantage of surgery is that your PSA after surgery should be zero or undetectable. It is a piece of mind for the family to know that the cancer is gone and you are cured from this disease.

A lot of times after radiation there could be a couple of years, 18 months to 24 months that the PSA can fluctuate and that can be a major source of emotional distress for your family.

With radiation, the prostate still remains in the body so that patient may continue to need some biopsies whereas the person who has had surgery may not need another biopsy.

What The Research Shows About Radiation Vs Surgery

The ProtecT trial was a 10-year, randomized clinical study designed to compare radical prostatectomy, external-beam radiotherapy and active surveillance for the treatment of localized prostate cancer.

The results, published in 2016, showed that the rate of disease progression among men assigned to radiotherapy or radical prostatectomy was less than half the rate among men assigned to active monitoring. However, there was no significant difference in survival at the median 10-year mark for radiation therapy, surgery or active surveillance.

If youre interested in directly comparing treatment outcomes by treatment method and risk group , the Prostate Cancer Free Foundation provides an interactive graph on its website with information from data obtained from over 100,000 prostate cancer patients over a 15-year period.

As discussed earlier in the sections on the side effects of radiation therapy and surgery, the researchers conducting the ProtecT trial also looked at side effects and quality-of-life issues and found that the three major side effects of these two treatment options that affect quality of life after prostate cancer treatment are urinary incontinence, sexual dysfunction and bowel health.

The trial found that urinary leakage and erectile dysfunction were more common after surgery than after radiation therapy. Gastrointestinal bowel problems were more common after radiation therapy.

Cancer That Clearly Has Spread

If the cancer has spread outside the prostate, it will most likely go to nearby lymph nodes first, and then to bones. Much less often the cancer will spread to the liver or other organs.

When prostate cancer has spread to other parts of the body , hormone therapy is probably the most effective treatment. But it isnt likely to cure the cancer, and at some point it might stop working. Usually the first treatment is a luteinizing hormone-releasing hormone agonist, LHRH antagonist, or orchiectomy, sometimes along with an anti-androgen drug or abiraterone. Another option might be to get chemotherapy along with the hormone therapy. Other treatments aimed at bone metastases might be used as well.

Who Is Eligible For Radiation Therapy For Prostate Cancer

Since low-risk cancers can grow slowly, “when a patients cancer is small and not aggressive, we recommend observation instead of an immediate course of radiation,” says Dr. Yu.

Yale Medicine doctor also look at the patients overall health to decide whether he is a good candidate. “Someone with a connective tissue disease, such as lupus, scleroderma, dermatomyositis or an inflammatory bowel disease, such as ulcerative colitis or Crohns disease, is not a good candidate, because he can suffer an inflated reaction to the radiation,” says Dr. Yu.

There are two kinds of radiation side effects: early and late. Early side effects, such as nausea and fatigue, usually donât last long. They may start during or right after treatment and last for several weeks after it ends, but then they get better. Late side effects, such as lung or heart problems, may take years to show up and are often permanent when they do.

The most common early side effects are fatigue and skin problems. You might get others, such as hair loss and nausea, depending on where you get radiation.

What Are The Different Types Of Internal Radiation Therapy

Brachytherapy and radiopharmaceuticals are both considered internal radiation therapies because they both work after being inserted inside the body, rather than being directed from outside. However, the similarities mostly end there. Brachytherapy works by implanting radioactive material into the prostate and is used for localized prostate cancer. Radiopharmaceuticals are injected into the bloodstream and are used for advanced, metastatic prostate cancer. Read on to find the details of each.

What Is Stereotactic Body Radiation Therapy And What Advantages Does It Offer

Traditionally, we deliver external beam radiation in 45 to 48 sessions over a span of ten weeks, using very sophisticated computer-based planning and enhanced imaging techniques and tumor tracking during the treatment. This is called image-guided IMRT and it is the current standard of care.

But there is increasing interest in giving this radiation in shorter courses of treatment. Many of the people we care for have a type of radiation therapy called MSK PreciseTM. MSK Precise is a form of SBRT that can be given in five sessions instead of the usual 45 to 50. MSK has been doing this for the past nine years, and the results in the several hundred people whove been treated have been excellent so far. The treatment is very well tolerated, with outcomes that are at least equivalent to and possibly better than the standard ten weeks of treatment. Because of its superior precision, MSK Precise has less side effects than more conventional radiation techniques, with extremely low rates of incontinence and rectal problems. The sexual side effects are low and similar to what is experienced with conventional external radiation techniques. And of course, its much more convenient for patients.

For patients with more-advanced tumors, we are completing a phase II trial in which were combining sophisticated brachytherapy approaches with MSK Precise. This kind of combination of dose-intense or escalated radiation may end up being a very effective regimen.
