Many personal, organisational and national factors can help or hinder men from choosing active surveillance over radical treatment when they have low-risk prostate cancer. Men are more likely to adhere to this plan of regular monitoring if they and their families are fully informed and understand that it includes the option of further treatment if necessary.
The recent ProtecT trial demonstrated that there was no difference in 10-year survival rates between men with low risk localised prostate cancer who were allocated to active surveillance and those who chose radical treatment. This is important because radical treatment carries the risk of side effects, such as incontinence and erectile dysfunction.
However, patient uptake of and adherence to active surveillance is generally low in clinical practice. This research suggests that efforts by clinicians to explain the choices available might help improve understanding, uptake or adherence. This will aid patients in making more informed decisions, potentially lessening the side effects experienced by some men.
Why was this study needed?
Prostate cancer is the most common form of cancer for men in the UK. Around 1 in 8 will be diagnosed at some point in their life, and the prognosis for those diagnosed can be very good.
Treatment options depend upon which stage the cancer is at and risk of spreading. Many low-risk prostate cancers grow only slowly and are unlikely to cause any trouble, as confirmed in the NIHR ProtecT study. Half to two-thirds of men diagnosed with low risk localised prostate cancer will not need treatment. Therefore, a policy of monitoring, known as active surveillance, is recommended. Unlike watchful waiting, active surveillance involves planned monitoring (such as regular blood tests or biopsies) and the option of treatment if required.
Not all eligible men opt for this method, instead choosing more radical treatments, such as radiotherapy or surgery, which can have side effects. This review sought to synthesise studies of the barriers and facilitators to using active surveillance.
What did this study do?
This was a large mixed methods review of 64 qualitative and observational studies. It drew on experiences of men in high-income countries and the average age at diagnosis was 65 years, so some aspects are potentially applicable to the UK, though some may be dependent on the health system and local guidelines.
Results could not be combined in a meta-analysis due to differing study designs. These included surveys, qualitative interviews, focus groups, registry and cohort studies. The review was well conducted and summarises the available information from the last 10 years on the topic.
What did it find?
- Family, friends and support groups play a key role in supporting men and influencing their decisions. Men feel that they have to justify their choice to their supporters, for whom ‘no treatment’ might be difficult to understand. Men's awareness of the options, and family education and reassurance about active surveillance, are linked with their ability to choose and adhere to this route.
- Men with less advanced cancer, lower PSA levels and Gleason scores, are more likely to choose and adhere to active surveillance than opt for treatment.
- Younger men (under 65) and those with a family history of prostate cancer are less likely to choose active surveillance.
- The clinician’s attitude, and how they communicated information about men’s options, could be either barriers or facilitators. For example, a good relationship with the clinician and receiving information from more than one member of the team makes choosing active surveillance more likely. Some clinicians do not offer the option of active surveillance at all.
- In non-UK countries, the existence and uptake of national guidance by healthcare organisations were linked with increased percentages of eligible patients using active surveillance.
What does current guidance say on this issue?
NICE 2014 guidance recommends active surveillance or radical treatments for men with localised prostate cancer at low to intermediate risk of progression.
NICE states that active surveillance involves an MRI scan followed by PSA tests every 3 to 4 months for the first year and then a repeat biopsy, followed by PSA tests every 3 to 6 months for the next two years, then every six months. Radical treatments are recommended for men with localised prostate cancer at high risk of progression.
Options include radical prostatectomy, external radiotherapy with hormone therapy or brachytherapy (insertion of radioactive implants into the prostate).
What are the implications?
Men with low-risk prostate cancer are influenced by several factors when choosing disease management strategies. They need more consistent information and help and support to choose and adhere to active surveillance where it is appropriate. For example, local policies and education could ensure active surveillance is taken up by more eligible men.
Perceptions also need to change as misconceptions about active surveillance are common.
Researchers suggest that improved clinician education, patient information and psychosocial support are required if active surveillance is to be seen and promoted as a valid and safe option.
