Box 2 Factors to consider when discussing active surveillance, radical prostatectomy or radical radiotherapy as treatment options for people with CPG 1, 2 and 3 localised prostate cancer, using evidence from a large UK trial
What are the treatment options for people with localised prostate cancer?
There are 3 options for treatment:
What effect does each treatment option have on survival at 10 years?
The evidence does not show a difference in the number of deaths from prostate cancer among people offered active surveillance, prostatectomy or radical radiotherapy.
People who had not died of prostate cancer were:
-
98 out of 100 patients offered active surveillance
-
99 out of 100 patients offered radical prostatectomy
-
99 out of 100 patients offered radical radiotherapy.
What effect does each treatment option have on disease progression at 10 years?
There is good evidence that both prostatectomy and radiotherapy reduce disease progression compared with active surveillance.
Signs of disease progression were reported in:
-
21 out of 100 patients offered active surveillance
-
8 out of 100 patients offered radical prostatectomy
-
8 out of 100 patients offered radical radiotherapy.
The trial defined disease progression as:
-
evidence of metastases or
-
diagnosis of clinical T3 or T4 disease or
-
need for long-term androgen deprivation therapy or
-
rectal fistula or the need for a urinary catheter owing to local tumour growth.
Disease progression was suspected if there was:
-
any rise in prostate-specific antigen (PSA) of more than 20% between consecutive measures at any time during follow up or
-
any rise in PSA level of 50% or more in any 12‑month period confirmed by repeat tests or
-
any indication of the appearance of symptomatic systemic disease.
What effect does each treatment option have on the rate of development of distant metastases at 10 years?
There is good evidence that both prostatectomy and radiotherapy reduce the rate of development of distant metastases compared with active surveillance.
Distant metastases were developed in:
-
8 out of 100 patients offered active surveillance
-
3 out of 100 patients offered radical prostatectomy
-
3 out of 100 patients offered radical radiotherapy.
What effect does each treatment option have on urinary function?
There is some evidence that urinary function is better for people offered active surveillance or radiotherapy than those offered prostatectomy.
At 6 months, problems with urinary continence were reported in:
-
39 out of 100 patients offered active surveillance
-
71 out of 100 patients offered radical prostatectomy
-
38 out of 100 patients offered radical radiotherapy.
At 6 years, problems with urinary continence were reported in:
-
50 out of 100 patients offered active surveillance
-
69 out of 100 patients offered radical prostatectomy
-
49 out of 100 patients offered radical radiotherapy.
At 6 months, moderate to severe urinary incontinence problems were reported in:
-
4 out of 100 patients offered active surveillance
-
19 out of 100 patients offered radical prostatectomy
-
6 out of 100 patients offered radical radiotherapy.
At 6 years, moderate to severe urinary incontinence problems were reported in:
-
8 out of 100 patients offered active surveillance
-
13 out of 100 patients offered radical prostatectomy
-
5 out of 100 patients offered radical radiotherapy.
What effect does each treatment option have on erectile dysfunction?
There is some limited evidence that sexual function is better for people offered active surveillance or radiotherapy than those offered prostatectomy.
At 6 months, moderate or severe problems with erectile dysfunction were reported in:
-
29 out of 100 patients offered active surveillance
-
66 out of 100 patients offered radical prostatectomy
-
48 out of 100 patients offered radical radiotherapy.
At 6 years, moderate or severe problems with erectile dysfunction were reported in:
-
40 out of 100 patients offered active surveillance
-
50 out of 100 patients offered radical prostatectomy
-
36 out of 100 patients offered radical radiotherapy.
What effect does each treatment option have on bowel function?
There is some evidence that bowel function is better for people offered active surveillance or prostatectomy than those offered radiotherapy in the short term.
At 6 months, problems with faecal incontinence more than once per week were reported in:
-
2 out of 100 patients offered active surveillance
-
1 out of 100 patients offered radical prostatectomy
-
5 out of 100 patients offered radical radiotherapy.
At 6 years, problems with faecal incontinence more than once per week were reported in:
-
3 out of 100 patients offered active surveillance
-
2 out of 100 patients offered radical prostatectomy
-
4 out of 100 patients offered radical radiotherapy.
At 6 months, moderate to severe impact of bowel habits on quality of life was reported in:
-
3 out of 100 patients offered active surveillance
-
3 out of 100 patients offered radical prostatectomy
-
10 out of 100 patients offered radical radiotherapy.
At 6 years, moderate to severe impact of bowel habits on quality of life was reported in:
-
4 out of 100 patients offered active surveillance
-
3 out of 100 patients offered radical prostatectomy
-
2 out of 100 patients offered radical radiotherapy.
