What Are The Side Effects Of Brachytherapy

How Long Does Radiation Therapy for Prostate Cancer Take?
  • Frequent urination or urinary retention or burning with urination
  • Erectile dysfunction
  • Urethral stricture or narrowing of the urethra
  • Diarrhea or blood in the stool
  • Secondary cancers

For the short time that the seeds are giving off larger amounts of radiation, you should avoid close proximity to children or pregnant women. Make sure to talk with your radiation oncologist or oncology nurse for instruction about radiation safety and exposure for family members or pets.

If you are traveling through an airport following brachytherapy treatment, there is a chance that radiation detectors will be set off. Talk to your radiation oncologist and ask for a note to indicate youve just had radiation treatment.

Q: Is Radiation Therapy Safe

Radiation therapy is safe when you go to a center that has a lot of experience and a system for quality assurance. Multiple members of our team look at a plan before its ever applied to a patient, says Dr. Gejerman. Our experienced team at John Theurer Cancer Center, who treats an extremely high volume of patients, has a robust review process to make sure everything is drawn properly before treatment is delivered.

Treatments For Prostate Cancer

    If you have prostate cancer, your healthcare team willcreate a treatment plan just for you. It will be based on your health andspecific information about the cancer. When deciding which treatments to offerfor prostate cancer, your healthcare team will consider:

    • the type and stage of the cancer
    • the grade or Gleason score
    • prostate-specific antigen levels
    • the risk group
    • possible side effects of treatments
    • your personal preferences
    • your overall healthand any existing medical conditions
    • your age and life expectancy
    • whether you have symptoms

    Prostate cancer treatments can seriously affect your qualityof life and cause side effects such as erectile dysfunction and incontinence . Manyprostate cancers grow slowly and cause no symptoms or problems.

    Impotence Risks After Prostatectomy

    Unfortunately, impotence continues to be a risk for radical prostatectomy. The recovery of potency depends on the stage of disease, the age of the patient, and the skill of the surgeon. However, a loss of potency can be treated with a number of technologies including medications, injections, and erectile devices. Furthermore, only erectile function is lost, and the patient retains sensory function. Its important to have a nuanced conversation with the patient so they understand the risk, and are able to make an informed decision.

    Recurrence Risk With Radiation Vs Surgery For Prostate Cancer

    Radiation Treatments for Prostate Cancer

    The fear of incontinence may be another deciding factor for some patients. Fortunately, especially with the advent of robotic surgery, most patients are able to become continent after a few weeks to months of stress incontinence. However, if a patient remains incontinent after 6 months, procedures like male urethral slings can also be performed to restore continence. Overall, almost no patients are rendered incontinent for life due to a radical prostatectomy, and should not avoid surgery due to this fear.

    How Does Hormone Therapy Work Against Prostate Cancer

    Early in their development, prostate cancers need androgens to grow. Hormone therapies, which are treatments that decrease androgen levels or block androgen action, can inhibit the growth of such prostate cancers, which are therefore called castration sensitive, androgen dependent, or androgen sensitive.

    Most prostate cancers eventually stop responding to hormone therapy and become castration resistant. That is, they continue to grow even when androgen levels in the body are extremely low or undetectable. In the past, these tumors were also called hormone resistant, androgen independent, or hormone refractory however, these terms are rarely used now because the tumors are not truly independent of androgens for their growth. In fact, some newer hormone therapies have become available that can be used to treat tumors that have become castration resistant.

    Frequent Urination Burning With Urination And Difficulty Urinating

    These are the most common complaints. Occasionally the urinary stream will weaken. Generally these symptoms are managed with medications to help the bladder function better or eliminate burning. Rarely, your doctor may order a urine test. Symptoms will resolve after the end of treatment. Contact your doctor if you see blood in your urine or if you are unable to urinate.

    What The Results Showed

    What Chesnut and his colleagues wanted to know was if the mens pre-operative findings were consistent with tumor details in their surgically removed prostates. And that turned out to be the case. The men truly did have treatable index lesions without other aggressive cancer, meaning that the biopsy and MRI results had accurately predicted PGA eligibility. Moreover, six additional men were found to be eligible for PGA based on tumor slide analysis, even though the pre-operative and MRI evidence had suggested otherwise.

    Given that, the authors concluded that 21 of the initial 77 men, or 27% in all, had recurring prostate cancer that was amenable to PGA.

    While the results are promising, the authors also cautioned that, given the small number of men evaluated and other study limitations, they are currently unable to recommend PGA as treatment for recurring prostate cancer outside of clinical trials.

    The authors have addressed a very important problem and one that has no easy answers, which is what to do about recurrent or persistent prostate cancer following radiation therapy, says Dr. Marc Garnick, the Gorman Brothers Professor of Medicine at Harvard Medical School and Beth Israel Deaconess Medical Center, editor of the Harvard Health Publishing Annual Report on Prostate Diseases, and editor in chief of HarvardProstateKnowledge.org.

    What Side Effects Will I Have

    How Do You Know Radiation Treatment for Prostate Cancer Worked?

    During your treatment, radiation must pass through your skin. You may notice some skin changes in the area exposed to radiation. Your skin may become red, swollen, warm, and sensitive, as if you have a sunburn. It may peel or become moist and tender. Depending on the dose of radiation you receive, you may notice a loss of hair or decreased perspiration within the treated area.

    These skin reactions are common and temporary. They will subside gradually within four to six weeks of completing treatment. If skin changes appear outside the treated area, inform your doctor or primary nurse.

    Long-term side effects, which can last up to a year or longer after treatment, may include a slight darkening of the skin, enlarged pores, increased or decreased sensitivity of the skin, and a thickening of tissue or skin.

    Another possible side effect is erectile dysfunction and urinary symptoms such as frequency, bleeding, or, rarely, incontinence. Keep these side effects in mind when considering your treatment options. If you have any concerns, don’t hesitate to talk to your doctor about them.

    If This Uncertainty Would Bother You So Much That It Would Affect Your Quality Of Life Surgery May Be A Better Option For You Phuoc Tran Md Phd

    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.

    Your Cancer Care Team

    People with cancer should be cared for by a multidisciplinary team . This is a team of specialists who work together to provide the best care and treatment.

    The team often consists of specialist cancer surgeons, oncologists , radiologists, pathologists, radiographers and specialist nurses.

    Other members may include physiotherapists, dietitians and occupational therapists. You may also have access to clinical psychology support.

    When deciding what treatment is best for you, your doctors will consider:

    • the type and size of the cancer
    • what grade it is
    • whether the cancer has spread to other parts of your body

    Proton Beam Radiati On Therapy

    Proton beam radiation therapy capitalizes on a unique physical property of high energy protons generated from a cyclotron. The accelerated charged particles travel through tissue until reaching a depth determined by their energy. Once they reach that depth, the remainder of the radiation dose is deposited in a sharp Bragg peak with no dose going beyond that point. When multiple proton beams are used, a very sharp and tight radiation dose distribution is created. This modality is especially attractive when tumors are in close proximity to sensitive organs. PCa is one of the more common indications in which proton therapy is utilized.

    At Washington University in St. Louis we are collaborating with investigators from Massachusetts General Hospital and the Harvard Medical School conducting a randomized clinical trial of IG-IMRT versus proton beam radiation in men with low and intermediate risk PCa. The PARTIQoL trial is seeking to measure and compare relative the impact of the two modalities on patient quality of life after treatment. provides a comparison of these two treatment modalities.

    What Types Of Radiotherapy Are There

    Brachytherapy Alone for Intermediate

    There are two common types of external beam radiotherapy:

    • intensity-modulated radiotherapy
    • 3-dimensional conformal radiotherapy .

    You may also hear about image guided radiotherapy . This is part of all radiotherapy treatments. Taking images of the prostate before each treatment allows your radiographer to make small changes to the area that is going to be treated, in case the prostate has moved slightly since your last treatment session. This makes sure the surrounding healthy tissue gets as little radiation as possible. It also makes sure the whole prostate is treated.

    Intensity-modulated radiotherapy

    This is the most common type of external beam radiotherapy in the UK. A computer uses the scans from your radiotherapy planning session to map the location, size and shape of your prostate. The radiotherapy machine gives beams of radiation that match the shape of the prostate as closely as possible. This helps to avoid damaging the healthy tissue around it, reducing the risk of side effects.

    The strength of the radiation can be controlled so that different areas get a different dose. This means a higher dose of radiation can be given to the prostate without causing too much damage to surrounding tissue.

    3D conformal radiotherapy

    As with IMRT, the radiation beams are mapped to the size, shape and position of the prostate. But the strength of the radiation cant be controlled in 3D-CRT, so all areas are treated with the same dose.

    Other types of radiotherapy

    Who Should Consider Taking Radiopharmaceuticals

    Radiopharmaceuticals are given through a vein to men with metastatic prostate cancer that has spread widely to the bone. Strontium89 and Samarium-153 are radiopharmaceuticals given to reduce the pain caused by the bone cancer. Radium-223, or Xofigo®, is a radiopharmaceutical given to prolong life.

    The side effects associated with radiopharmaceuticals are mainly the suppression, or lowering, of white blood cell and platelet levels in the blood. Your doctor will be able to assess whether your body can handle this side effect before you are given the treatment and will monitor your levels after you receive it. Your doctor, specialist nurse, or nuclear medicine practitioner will be able to give you more information about the treatment and possible side effects.

    If your doctor has told you that your bone metastases have spread, you may be a candidate for a radiopharmaceutical. Speak with your oncology team to see if one of these treatments may be right for you.

    What Is Intermittent Adt

    Researchers have investigated whether a technique called intermittent androgen deprivation can delay the development of hormone resistance. With intermittent androgen deprivation, hormone therapy is given in cycles with breaks between drug administrations, rather than continuously. An additional potential benefit of this approach is that the temporary break from the side effects of hormone therapy may improve a mans quality of life.

    Randomized clinical trials have shown similar overall survival with continuous ADT or intermittent ADT among men with metastatic or recurrent prostate cancer, with a reduction in some side effects for intermittent ADT .

    Who Should Consider External Beam Radiation Therapy

    In most cases, external beam radiation therapy is used for men with localized prostate cancer . The intent of EBRT in this case is to kill the tumor while sparing as much healthy tissue as possible. Sometimes it is used in more advanced cases. For example, it can be used along with hormone therapy, or used to relieve pain from bone metastases.

    What Are The Treatments For Localized Prostate Cancer

    What is Radiation Treatment for Prostate Cancer?
    • Surgery takes out the prostate and any nearby tissue that may contain cancer, including lymph nodes. This surgery is called a radical prostatectomy . A doctor can do it as open surgery by making a cut, or incision, in your belly or groin. Or he or she can do laparoscopic surgery by putting a lighted tube, or scope, and other surgical tools through much smaller cuts in your belly or groin. The doctor is able to see your prostate and other organs with the scope. In some places, robot-assisted laparoscopic prostatectomy may be done. In this type of surgery, the surgeon controls the robotic arms that hold the tools and scope.
    • Radiation uses X-rays and other types of radiation to kill the cancer cells. This may be done with:
    • External-beam radiation, in which a machine aims high-energy rays at the cancer.
    • Brachytherapy , in which tiny pellets of radioactive material are injected into or near the cancer.
    • Both kinds of radiation.

    Radiation and surgery are treatments that destroy or remove localized prostate cancer. Both treatments also have long-term side effects, like bladder, bowel, and erection problems.

    In the first 2 to 5 years after treatment, the chance of having erection or bladder problems is higher with surgery. And the chance of having bowel problems, such as an urgent need to move your bowels, is higher with radiation. But at 15 years, the chance of erection, bladder, or bowel problems is about the same with either treatment.footnote 3

    Focal Therapy For Prostate Cancer

    With recent advances in MRI and targeted biopsy, we are better able to locate the exact area of prostate cancer. Men who do not have an enlarged prostate, who have prostate cancer that is detected only in a single region of the prostate and have intermediate grade cancer can be a candidate for focal therapy. This type of therapy treats only the cancerous tissue and spares the normal prostate, thereby preserving urinary and sexual function

    Here at UCLA we commonly use cryotherapy or HIFU to focally treat prostate cancer. Given that this is a relatively new form of treatment, we have established rigorous post-treatment protocols using MRI and biopsies to ensure that the cancer has been adequately treated.

    Treatment By Stage Of Prostate Cancer

    Different treatments may be recommended for each stage of prostate cancer. Your doctor will recommend a specific treatment plan for you based on the cancers stage and other factors. Detailed descriptions of each type of treatment are provided earlier on this same page. Clinical trials may also be a treatment option for each stage.

    Early-stage prostate cancer

    Early-stage prostate cancer usually grows very slowly and may take years to cause any symptoms or other health problems, if it ever does at all. As a result, active surveillance or watchful waiting may be recommended. Radiation therapy or surgery may also be suggested, as well as treatment in clinical trials. For those with a higher Gleason score, the cancer may be faster growing, so radical prostatectomy and radiation therapy are often recommended. Your doctor will consider your age and general health before recommending a treatment plan.

    ASCO, the American Urological Association, American Society of Radiation Oncology, and the Society of Urologic Oncology recommend that patients with high-risk early-stage prostate cancer that has not spread to other areas of the body should receive radical prostatectomy or radiation therapy with hormonal therapy as standard treatment options.

    Locally advanced prostate cancer

    Watchful waiting may be considered for older adults who are not expected to live for a long time and whose cancer is not causing symptoms or for those who have another, more serious illness.
