Low dose-rate prostate brachytherapy
Self-learning tutorial
- A self-learning slide tutorial, including detailed slide notes, to work through at your own pace
- Part of the Prostate Brachytherapy Advisory Group (PBAG) online nurse education programme
Why is it being provided?
- To help you understand more about prostate brachytherapy, an increasingly popular alternative to prostatectomy and external beam radiotherapy (EBRT), for patients with localised prostate cancer
To view the detailed notes, select either ‘View Normal’ or ‘View Notes Pages’

- To print the notes and the slides, select ‘Print notes pages’
2008 NICE guideline on prostate cancer identified prostate brachytherapy, along with prostatectomy and EBRT, as one of the three proven radical treatment options for men with low- or intermediate-risk localised prostate cancer
NICE prostate cancer guideline2008 NICE guideline on the diagnosis and treatment of prostate cancer
Prostate brachytherapy involves the transperineal placement of radioactive seeds directly into the prostate
- This treatment delivers a high dose of radiation directly into the prostate
- During the procedure, rectal ultrasound is used to assess the size and shape of the prostate
The seeds are placed into the prostate through fine hollow needles inserted into the perineum
- A grid-like device is used to guide the needles into the correct position
- A computer program ensures that the right dose of radiation is delivered to the prostate and that other organs are unaffected
- The seeds stay in the prostate permanently and remain radioactive for 3-9 months

- Many patients with localised prostate cancer are potential candidates for prostate brachytherapy
- Patient characteristics including cancer risk, age and prostate size, help to determine which treatment is most appropriate
Prostate brachytherapy is associated with fewer complications and side-effects than other radical treatments

What are the side-effects?Numerous clinical studies have shown that prostate brachytherapy is highly effective at curing cancer and prolonging survival in patients with localised prostate cancer
Clinical efficacy of prostate brachytherapy (1)Prostate brachytherapy, prostatectomy and EBRT are equally effective at curing cancer and prolonging survival in patients with localised prostate cancer

Prostate brachytherapy, prostatectomy and EBRT have different effects on patients’ quality of life
- Treatment decisions should take into account the effects of treatment on quality of life, as well as survival

Advantages
Disadvantages
Patients can experience transient urinary irritative symptoms
Close contact with small children and pregnant women should be avoided in first 2 months after treatment
- Avoids physical trauma of a major surgical procedure
- One-off minimally invasive procedure requiring minimal hospitalilsation
- Procedure causes minimal bleeding
- Precise placement of the seeds offers more tailored treatment
- Relatively few long-term side-effects
- Quick recovery and return to normal activity
- More likely to retain quality of life compared with other treatments
- Maintains sexual potency in many patients
- Produces good long-term clinical outcomes
- Cost-effective treatment option
- Equivalent efficacy to prostatectomy and EBRT
- Quality of life
- Quality of life is more likely to be retained than after prostatectomy or EBRT
- Side effects are generally not as serious; sexual side-effects are less common than after prostatectomy
- Hospital stay
- Prostate brachytherapy: 1 or 2 day visits
- EBRT: many day visits(5 days-a-week for 4–7 weeks)
- Prostatectomy: prolonged hospital stay (up to 1 week)

An increasingly popular alternative to other recommended radical treatments for localised prostate cancer
- Involves the transperineal placement of radioactive seeds directly into the prostate
- As effective as other recommended radical treatments at curing cancer and prolonging patient survival
- More likely to retain quality of life than other radical treatments
The number of NHS and private hospitals and centres in the UK currently providing LDR prostate brachytherapy are:
England: 29
Scotland: 2 (Glasgow and Edinburgh)
Wales: 1 (Cardiff)
Ireland 2 (Dublin and Galway)
