Gold Seeds In Prostate Cancer Treatment

Whos Eligible For This Procedure

Transperineal implantation procedure of Gold Anchor fiducial markers in prostate

Permanent implants are relatively low-energy sources, and therefore have limited tissue penetration. A well-done implant treats the prostate and the surrounding few millimeters of adjacent tissue.

The best candidates for this procedure are patients with a cancer within or near the prostate. Patients with prostate cancer thats invading nearby structures like the bladder or rectum arent appropriate for this technique.

What Are The Side Effects

Urinary symptoms are the most common. These include frequent urination and a need to get to the bathroom quickly. Some men have a burning with urination and, in a few cases, an inability to empty the bladder completely.

These symptoms can usually be managed with medicine, and they improve over time. Temporary self-catheterization may be necessary to help drain the bladder.

Urinary incontinence from brachytherapy is rare. The risk may be somewhat increased in patients who have undergone a previous surgical procedure to remove a part of the prostate called a TURP . A doctor can minimize this risk by doing a careful prostate ultrasound before the procedure to determine how much prostate tissue is still present to implant the seeds.

Rectal bleeding occurs in less than 1% of patients. Diarrhea is rare.

The impotence rate at five years after the procedure is about 25% using brachytherapy alone. If hormone therapy is added, the impotence rate rises depending on the duration of the hormonal treatment.

Bowel problems can sometimes happen and include rectal pain, burning pain and diarrhea.

The Initial Causes Gold Seeds For Prostate Cancer

One of the first symptoms of prostate issues is pain or tenderness in the groin or lower back. This can be the result of a noncancerous condition called enlarged prostatic tissue, or it could be an infection of the bladder. In either case, its important to see a doctor as soon as possible. If youre suffering from prostate pain, you may want to consider reducing your caffeine intake.

Another symptom of a potentially enlarged prostate is difficulty starting a stream of urine, leaking, or dribbling. These symptoms are not serious, but theyre still alarming. Most men put up with an enlarged prostate for years before seeking medical attention, but they typically seek treatment as soon as they notice symptoms. Even if you dont have symptoms, its worth getting checked to determine if you have any prostate issues.

If you experience nightly bathroom runs, you may be experiencing an enlarged prostate. You may be having difficulty starting a stream of urine, or you may even be dribbling or leaking during the day. These problems arent life-threatening, but can become a nuisance. You should not ignore these signs and seek treatment as soon as you notice them. If you feel any of these symptoms, you should consult a doctor.

We use real time, 3-dimensional imaging to carefully place each seed at a predetermined location and depth. In this way, we cover the entire gland and the cancer site. The number of seeds implanted into your prostate will depend on your unique anatomy.

We place an ultrasound probe in your rectum to image the prostate. We also use continuous X-ray imaging. Together, these provide a magnified, 3D view of your prostate during the procedure. After the implantationand while you are still anesthetizedwe will check your urethra and bladder and retrieve any seeds found in your bladder.

Who Can Have Permanent Seed Brachytherapy

On its own

Permanent seed brachytherapy on its own may be suitable for men with CPG 1 localised prostate cancer. This is because the radiation from the radioactive seeds doesnt travel very far, so will only treat cancer that is still inside the prostate.

It may also be suitable for some men whose cancer have a CPG 2 or CPG 3 of spreading.

With other treatments

If you have CPG 4 or CPG 5 localised prostate cancer, you may have brachytherapy together with external beam radiotherapy and hormone therapy. This is sometimes called a brachytherapy boost. Having these other treatments at the same time as permanent seed brachytherapy can help make the treatment more effective. But it can also increase the risk of side effects.

Some men with intermediate risk localised prostate cancer or locally advanced prostate cancer may be offered a brachytherapy boost.

When is permanent seed brachytherapy not suitable?

Permanent seed brachytherapy wont be suitable if your cancer has spread to other parts of your body .

It may not be suitable if you have a very large prostate. If you do have a large prostate you may be able to have hormone therapy before treatment to shrink your prostate.

Not all hospitals offer permanent seed brachytherapy. If your hospital doesnt do it, your doctor may refer you to one that does.

Exeter Hospital Doctor Uses Tiny Seeds To Accurately Track The Prostate So High Doses Of Radiation Can Be Targeted To A More Precise Area

Prostate cancer is the most common form of the disease among men. It will strike one in six. And one in 35 will die of it, according to the American Cancer Society.

The latest treatment at the Exeter Hospitals Center for Cancer Care hopes to lower that rate. Gary Proulx, MD, the director of the Radiation Therapy Program at the hospital, says hes seeing great results, thanks to a tiny gold seed, about the size of a grain of rice.

The treatment is known as the fiducial marker and is considered more accurate and effective than other forms. Its a fairly recent procedure being introduced to the Seacoast for the first time, he says.

The seeds are not radioactive. I want to emphasize that, says Proulx. The improve the imaging in treatment for prostate cancer. Youre able to locate the prostate before treatment and therefore adjust treatment so youre more accurate, it reduces side-effects as well.

Proulx is a graduate of Harvard Medical School and assumed leadership of Exeters radiation therapy program in March through collaboration between Exeter Hospital and the Massachusetts General Hospital Cancer Center. Proulx brings his own experience using the gold seed technology from his previous post as the chairman of radiation oncology and medical director of the Guthrie Health Cancer Center and Cancer Treatment Services. That center is part of a 238-bed tertiary care teaching hospital in Sayre, Pa.

Symptomatic treatment of an enlarged prostate usually involves a combination of medication and lifestyle changes. A diet rich in fruits and vegetables may be the best option if you suffer from chronic urination. It will help the body adjust to the increased size of the prostate. Also, taking regular urination intervals will help retrain the bladder to function properly. Inactivity also contributes to urine retention, and cold temperatures can increase the urge to urinate.

Invasive treatment of enlarged prostate includes medication that relieves the pressure on the urethra and bladder. However, if the condition is severe, it may require surgical intervention. If treatment is not successful, the enlarged prostate can become a potentially life-threatening disease. As the hormone levels in the body change, the enlarged prostate can lead to various complications, including urinary retention and even cancer. This is why it is critical to see a doctor for further evaluation.

A physician can recommend a number of treatments to address an enlarged prostate. An enlarged prostate will require surgery to relieve the symptoms. In most cases, surgical treatment for an enlargement of the penis is enough. Moreover, a doctor may recommend a course of treatment based on symptoms. A TURP procedure is not painful and requires less recovery time than open surgery. The recovery period will be shorter and less traumatic.

What Does Treatment Involve

You will be referred to a specialist who treats cancer with radiotherapy, called a clinical oncologist. The treatment itself may be planned and carried out by other specialists including a therapy radiographer, a radiologist, a urologist, a physicist and sometimes a specialist nurse.

Each hospital may do things slightly differently but you will usually have:

  • an appointment to check the treatment is suitable for you
  • a planning session, to plan the treatment
  • the treatment itself.

The planning session and the treatment itself may be on the same day , or on two separate hospital visits .

Before the planning session, let your specialist know if you are taking any medicines, especially medicines that thin your blood such as aspirin, warfarin or clopidogrel. Dont stop taking any medicines without speaking to your doctor, nurse or radiographer.

One-stage procedure

Many hospitals offer treatment in just one visit, where you will have the planning session and the seeds put in at the same time under the same anaesthetic. You may not need to stay in hospital overnight.

You will have had an appointment one or two weeks before your procedure to check that the treatment is suitable for you. At this appointment, youll have had an ultrasound scan to check the size of your prostate and work out how many seeds you need. You wont need an anaesthetic for this scan.

Two-stage procedure

Your planning session

A thin tube may be passed up your penis into your bladder to drain urine.

  • You might see blood in your bowel movements. You might also have a small amount of bleeding from your rectum. These can happen right after your procedure or for the next few days when you have a bowel movement.
  • You might see blood in your urine for 7 to 14 days after your procedure. This bleeding might come and go.
  • Your semen might look rust-colored for up to 12 weeks after your procedure. This is because small amounts of blood might be in it.

Permanent Seed Brachytherapy For Prostate Cancer

Permanent seed brachytherapy is when your doctor puts very small radioactive metal seeds into your prostate gland. The seeds slowly release a low level of radiation into the area of the prostate over a few months. It is a type of internal radiotherapy.

With brachytherapy, your doctor puts the radioactive source or seeds as close to the cancer as possible. So that the cancer gets a high dose but nearby tissues and further away the levels of radiation are low.

What You Need To Know About The Prostate Gold Seeds In Prostate Cancer Treatment

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.

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.

What Happens Before The Procedure

A transrectal ultrasound is done to provide the radiation oncologist with specific details about your case. Newer techniques using a CAT scan or MRI may be used to guide the proper placement of the implants. This information is used to custom-design the treatment plan for you. Another option is for the ultrasound and treatment plan to be done at the same time as the radioactive seeds are implanted.

The only other thing I was drinking in the first 6 months after my diagnosis was green tea. I would drink about 4 glasses of green tea daily to go along with the increased water intake. I wasnt putting any other liquid into my body for the first 6 months. This was a big help in starting my road to recovery.

Once I started feeling better then I added organic soy milk to my diet as well. Soy milk isnt much like regular milk but once you get used to it then its not bad at all. To this day these are the only 3 liquids I have in my diet. To recap the 3 liquids I drink today are purified water,green tea,& organic soy milk. I put no other liquids into my body period.

Now, I want to chat a little more about meat & other aspects of a proper diet. As I said we dont need meat to live. I thought cutting or limiting meat in my diet would be to hard to accomplish. Well again my thinking was wrong. Was it easy? No! However, after a couple weeks then things were starting to get easier. I didnt cut all meats out of my diet but I did cut certain meats & eat moderate amounts of all others.

One meat that needs to be completely cut or at least very minimized is red meat . Too much Red meat consumption is not good for prostate health. I was eating a lot of fast food burgers & also red meat at home. I will say to at least cut red meat completely out of your diet until you get your prostate health back.

What Is The Radioactive Seed Implant Procedure

What is it like having Prostate Radiotherapy treatment?

Permanent radioactive seed implants are a form of radiation therapy for prostate cancer. The terms “brachytherapy” or “internal radiation therapy” might also be used to describe this procedure.

During the procedure, radioactive seeds are implanted into the prostate gland using ultrasound guidance. The number of seeds and where theyre placed is determined by a computer-generated treatment plan tailored for each patient. About 100 seeds are commonly implanted.

The implants remain in place permanently, and become biologically inert after about 10 months. This technique allows a high dose of radiation to be delivered to the prostate with limited damage to surrounding tissues.

Radioactive seed implants are an outpatient procedure. Compared to external radiation which requires up to seven to seven-and-a-half weeks of daily treatments convenience is a major advantage of this treatment option.
