Psychosocial consequences of potential overdiagnosis in prostate cancer a qualitative interview study

Abstract

Background: Prostate cancer is a frequently diagnosed cancer and made up 6% of male cancer deaths globally in 2008. Its incidence varies more than 25-fold worldwide, which is primarily attributed to the implementation of the prostate-specific antigen (PSA) test in developed countries. To reduce harm of overdiagnosis, most international guidelines recommend surveillance programmes. However, this approach can entail negative psychosocial consequences from being under surveillance for an (over)diagnosed prostate cancer. Aim: To explore men's feelings and experiences in a surveillance programme. Design and setting: Qualitative study with Danish men diagnosed with asymptomatic prostate cancer Gleason score 6, who are in a surveillance programme Methods: 12 semi-structured, individual interviews were conducted and analysed with systematic text condensation and selected theories. Results: Most informants reported that they were astonished at the time of diagnosis. They were aware of the small likelihood of dying from cancer, but in some cases, the uncertainty created ambivalence between knowing and not knowing. The men expressed their risk awareness in different ways: a realization that life does not last forever, uncertainty towards the future, a feeling of powerlessness, and a need for control. Conclusions: The men in this study had substantial psychosocial consequences from being labelled with a cancer diagnosis. Bearing these men's high risk of overdiagnosis in mind, it is important to discuss whether the harms of this diagnosis outweigh the benefits. The psychosocial consequences of being in a prostate cancer surveillance programme should be explored further. KEY POINTS Current awareness: The number of men living with an asymptomatic prostate cancer has increased the last 20 years after the implementation of the PSA test. Main Statements: Men living with an asymptomatic, low-risk prostate cancer experience negative psychocosial consequences GPs should consider the possible negative psychosocial consequences in their decision-making of measuring the PSA level ARTICLE HISTORY

Managing lower urinary tract symptoms in primary care: qualitative study of GPs’ and patients’ experiences

“…Research suggests that surveillance for (over)diagnosed prostate cancer can have negative psychological consequences such as feelings of uncertainty and powerlessness. 20 Consistent with existing findings, 6 over half of patients in this study had received no prior treatment for their LUTS. As reported previously, 13 patients perceived this to be because their symptoms were age-related.…”

The Tyranny of Numbers: How e-Health Record Transparency Affects Patients’ Health Perceptions and Conversations with Physicians

“…However, the limits of the test are that what it mainly picks up are cancers that are unlikely to cause any harm (ibid.). To have a positive PSA test might mean men unnecessarily living with the stigma of having cancer and the side effects of unnecessary treatment, such as incontinence and erectile dysfunction (Nielsen et al 2020). This argument was confirmed when we met Eric, a 70-year-old retired sailor, who had been diagnosed with prostate cancer ten years earlier.…”

I would rather be vaguely right than precisely wrong

“…On the other hand, a clinician may order a test or a scan that results in a false-positive finding, indicating that the patient has a medical problem he does not really have. That may lead to other tests, biopsies, and even potentially harmful treatment, for a non-existing disease or an unimportant problem [ 3 ].…”
