What are the two types of brachytherapy?

There are two main forms of brachytherapy – intracavitary treatment and interstitial treatment. With intracavitary treatment, the radioactive sources are put into a space near where the tumor is located, such as the cervix, the vagina or the windpipe.

How many sessions of brachytherapy are there?

You may undergo one or two sessions a day over a number of days or weeks. You’ll lie in a comfortable position during high-dose-rate brachytherapy. Your radiation therapy team will position the radiation device.

What type of radiation is used in brachytherapy?

Brachytherapy is a form of radiation therapy where a sealed radioactive source is placed, inside, on or near the tumour. Brachy comes from the Greek word for short. It is often thought of as ‘internal radiation therapy’. These sources produce gamma-rays, which have the same effect on cancer cells as X-rays.

What are the disadvantages of brachytherapy?

Disadvantages of brachytherapy

You need a general or a spinal anaesthetic. With radioactive seeds (not with HDR brachytherapy) you need to avoid close contact with children or anyone who is pregnant for a few months after treatment.

What is the success rate of brachytherapy?

When it comes to early stages of disease, patients very frequently do well with either brachytherapy or external beam radiation. Success rates of around 90% or higher can be achieved with either approach.

What are the three types of brachytherapy?

Sure, there are 3 types of brachytherapy: low-dose rate implants, high-dose rate implants, and permanent implants. Low-dose rate implants, often called LDR for short, are implants that stay in for 7 days or less before they are taken out.

How long does brachytherapy take?

Brachytherapy takes 30 minutes or more, depending on the type of therapy you have. Before the procedure, you will be given medicine so that you do not feel pain. You may receive: A sedative to make you drowsy and numbing medicine on your perineum.

How long does radiation stay in your body after brachytherapy?

They attach the tubes to a brachytherapy machine. The radioactive source moves from the machine through the tubes to the cancer. The radioactive source may stay inside your body for about 10 to 20 minutes.

How long does radiation last after brachytherapy?

Permanent prostate brachytherapy involves placing many radioactive seeds within the prostate to treat prostate cancer. During the procedure, an ultrasound probe is placed in the rectum to help guide the placement of seeds. The seeds emit radiation that dissipates over a few months.

Can brachytherapy be repeated?

As primary salvage low-dose-rate brachytherapy (LDR-BT) has shown to be safe and feasible [10], one can consider to perform a second salvage treatment in a selected group of patients (> 3-year interval between treatment, prostate-specific antigen [PSA] doubling time > 1 year and acceptable toxicity after 1st salvage …

Are you put to sleep for brachytherapy?

The implant procedure is usually done in a hospital operating room designed to keep the radiation inside the room. You’ll get anesthesia, which may be either general (where drugs are used to put you into a deep sleep so that you don’t feel pain) or local (where part of your body is numbed).

How do you feel after brachytherapy?

Brachytherapy can make you feel very tired and physically weak. This is called fatigue. It is not like usual tiredness – you may feel exhausted after doing nothing. This is simply your body responding to the treatment, as it tries to repair any healthy cells the brachytherapy has damaged.

Do you lose your hair with brachytherapy?

For most treatment sites, patients should be able to return home and normal activity immediately following treatment. There are no side effects like nausea, hair loss or diarrhea following this procedure.

Do you need a catheter after brachytherapy?

You may need to use a urinary catheter for 1 or 2 days if you have a lot of blood in your urine. Your health care provider will show you how to use it. You may also feel the urge to urinate more often.

Can you walk after brachytherapy?

Patients could resume walking within a few hours of the procedure and other normal activity within a few days, partly due to the minimally invasive nature of the procedure.

Are you awake during brachytherapy?

If you are taken to the Operating Room, you will receive anesthesia. If you are taken to the Radiation Oncology Department, you will be awake but drowsy. The sensation caused by the procedure is best described as “pressure” while the applicator is being placed and the vagina is being packed with gauze.

Can I eat before brachytherapy?

You need to drink lots of clear fluids (at least 2 litres). You cannot have anything to eat or drink after midnight on the night before the procedure. This includes water, coffee, tea, and gum. The anesthesiologist may tell you to take medications with a small amount of water on the morning of brachytherapy.

Is urine contaminated with brachytherapy?

Keep in mind objects that you touch or items that you use do not become radioactive. Bodily waste, such as urine and stool are not radioactive.

When is brachytherapy not suitable?

Permanent seed brachytherapy won’t be suitable if your cancer has spread to other parts of your body (advanced prostate cancer). 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.

Do you need anesthesia for brachytherapy?

Hence, brachytherapy for breast cancer requires short anaesthesia for insertion of the applicators and analgesia while they are in place. Removal of the applicators usually does not require anaesthesia.
