With active surveillance, you undergo periodic testing to monitor your cancer, with the idea that — at least initially — you can avoid urinary, sexual and rectal side effects that accompany curative treatments like surgery and radiation. Then, if your test results suggest your cancer is progressing, you can still be treated and cured.
Although research suggests this strategy is safe and effective for properly selected patients, some recent studies indicate that a significant number of men on active surveillance aren’t adhering to guideline-recommended follow-up protocols, potentially placing themselves at risk.
“It is a concern,” says urologist and surgeon Eric Klein, MD. “To do surveillance safely, patients need to be monitored for progression.”
How is prostate cancer monitored?
Although organizations have issued guidelines for how men on active surveillance should be followed, there’s no consensus on the ideal active surveillance management strategy.
In general, active surveillance includes:
- Periodic prostate-specific antigen (PSA) blood tests.
- Digital rectal exams.
- Prostate biopsies.
Many experts, including Dr. Klein, also incorporate advanced genomic testing and MRI with targeted biopsy into their active surveillance regimens.
Until recently, we haven’t really had the tools to assess an individual’s change in biology in real time. Now, MRI and targeted biopsy and genomic testing should allow us to do that.
The interval at which these tests should be done varies, depending on the volume and aggressiveness of your cancer, your age and other individual characteristics. Whatever strategy your physician employs, it’s vital to return for follow-up testing.
However, in one study, researchers reviewing registry data on more than 2,200 patients reported that within two years of being on active surveillance, about 1 in 10 of the men were lost to follow-up. (That was defined as any 18-month period in which no pertinent surveillance testing was entered into the registry.)
Additionally, in a study presented at the American Society of Clinical Oncology (ASCO) annual meeting in June 2019, researchers noted that among 346 men on active surveillance, only about one-third adhered to guideline-recommended monitoring (PSA testing every three to six months and a prostate biopsy within 18 months of initial diagnosis.)
“We have a pretty good idea of who are the best candidates for active surveillance,” Dr. Kleins says. “But really, we don’t have evidence that says that patients with these initial characteristics should have PSAs at this interval, MRIs at this interval and biopsies at this interval. It’s my gut sense that it’s different for different people.”
Is active surveillance right for you?
In gauging if you’re eligible for active surveillance, your physician will consider your:
- Gleason score (a measure of how likely your prostate cancer will spread).
- PSA results, the volume of cancer found on biopsy and the risk category of your cancer.
- Overall health and life expectancy.
“To be eligible for surveillance, you have to meet two criteria: One is the biological criteria, meaning you have to have the right tumor,” Dr. Klein explains. “The second is you have to have the right psyche. Active surveillance is not for everyone.”
In making your decision about active surveillance, ask yourself: Can you commit to repeated testing (including prostate biopsies), which can cause some pain and carry a risk (albeit low) of infection?
And carefully assess whether you can live with the idea of having an untreated cancer. In the study presented at the 2019 ASCO meeting, few men expressed regret about choosing active surveillance, but 16% of them converted to curative treatment within the first two years. The reason? The study authors say it was likely driven by patient anxiety, not disease-related factors.
Nevertheless, active survelliance remains a viable option for the right men. Just be sure to ask your doctor what to expect.
“When someone is newly diagnosed with prostate cancer, the first question they should ask ought to be not what’s the best treatment, but does the cancer need treatment?” Dr. Klein advises. “That’s what I would encourage any patient to ask.”
What you can do
- Ask if you’re a candidate for active surveillance, and carefully weigh the risks and benefits with your physician.
- Review your follow-up testing protocol with your doctor. After each visit, try to schedule your next appointment before you leave, and ask if the physician’s office will send you a reminder.
- Recognize that choosing active surveillance means delaying treatment and its side effects, but not necessarily avoiding treatment altogether.
- If you have anxiety about active surveillance or having prostate cancer, seek out a local support group, and talk to other men who’ve been on active surveillance to gain insight into what you can expect.
