Determinants for choosing and adhering to active surveillance for localised prostate cancer: a nationwide population-based study.

ABSTRACT:

Objective

Knowledge about factors influencing choice of and adherence to active surveillance (AS) for prostate cancer (PC) is scarce. We aim to identify which factors most affected choosing and adhering to AS and to quantify their relative importance.

Design, setting and participants

In 2015, we sent a questionnaire to all Swedish men aged ?70 years registered in the National Prostate Cancer Register of Sweden who were diagnosed in 2008 with low-risk PC and had undergone prostatectomy, radiotherapy or started on AS.

Outcome measurements and statistical analysis

Logistic regression was used to calculate ORs with 95% CIs for factors potentially affecting choice and adherence to AS.

Results

1288 out of 1720 men (75%) responded, 451 (35%) chose AS and 837 (65%) underwent curative treatment. Of those starting on AS, 238 (53%) diverted to treatment within 7?years. Most men (83%) choose AS because 'My doctor recommended AS'. Factors associated with choosing AS over treatment were older age (OR 1.81, 95%?CI 1.29 to 2.54), a Charlson Comorbidity Index >2 (OR 1.50, 95%?CI 1.06 to 2.13), being unaccompanied when notified of the cancer diagnosis (OR 1.45, 95%?CI 1.11 to 1.89). Men with a higher prostate-specific antigen (PSA) at the time of diagnosis were less likely to adhere to AS (OR 0.26, 95%?CI 0.10 to 0.63). The reason for having treatment after initial AS was 'the PSA level was rising' in 55% and biopsy findings in 36%.

Conclusions

A doctor's recommendation strongly affects which treatment is chosen for men with low-risk PC. Rising PSA values were the main factor for initiating treatment for men on AS. These findings need be considered by healthcare providers who wish to increase the uptake of and adherence to AS.

Project description:IntroductionOne in five men is likely to receive a diagnosis of prostate cancer (PCa) by the age of 85 years. Men diagnosed with low-risk PCa may be eligible for active surveillance (AS) to monitor their cancer to ensure that any changes are discovered and responded to in a timely way. Communication of risk in this context is more complicated than determining a numerical probability of risk, as patients wish to understand the implications of risk on their lives in concrete terms. Our study will examine how risk for PCa is perceived, experienced and communicated by patients using AS with their health professionals, and the implications for treatment and care.Methods and analysisThis is a proof of concept study, testing out a multimethod, qualitative approach to data collection in the context of PCa for the first time in Australia. It is being conducted from November 2016 to December 2017 in an Australian university hospital urology clinic. Participants are 10 men with a diagnosis of localised PCa, who are using an AS protocol, and 5 health professionals who work with this patient group (eg, urologists and Pca nurses). Data will be collected using observations of patient consultations with health professionals, patient questionnaires and interviews, and interviews with healthcare professionals. Analysis will be conducted in two stages. First, observational data from consultations will be analysed thematically to encapsulate various dimensions of risk classification and consultation dialogue. Second, interview data will be coded to derive meaning in text and analysed thematically. Overarching themes will represent patient and health professional perspectives of risk communication.Ethics and disseminationEthical approval for the study has been granted by Macquarie University Human Research Ethics Committee, approval 5201600638. Knowledge translation will be achieved through publications, reports and conference presentations to patients, families, clinicians and researchers.

Project description:ObjectiveLittle is known about clinicians' decision-making about decreasing active surveillance (AS) testing/converting patients to watchful waiting (WW), nor are there any guidelines. The objective of this study was to identify factors that clinicians consider when decreasing AS testing/converting to WW for men with prostate cancer.DesignExploratory qualitative study.SettingAll participants practiced in various institutions in the USA.ParticipantsEligible clinicians had to provide clinical care for patients with prostate cancer in the USA and speak English. Clinicians could be either urologists or radiation oncologists. Of the 24 clinicians, 83% were urologists representing 11 states, 92% were men and 62% were white.MethodsThis qualitative study used data from semi-structured interviews. Purposive sampling was used to ensure geographical variation in the USA. Data collection continued until thematic saturation was achieved. Framework analysis guided coding and identification of themes. Two researchers coded all transcripts independently, met to discuss and reached consensus.ResultsInterviews with clinicians demonstrated that testing or monitoring for AS or transitioning to WW is happening in practice, whether intentionally or unintentionally. Decisions to decrease AS were personalised and tailored to patients' health status. Life expectancy was the dominant factor that influenced decision, but clinicians were generally hesitant to specify an age when they would decrease AS or transition to WW. Fear that poor adherence could lead to missed progression and concerns about the medico-legal issue of not doing enough were cited as barriers to decreasing AS.ConclusionsThese findings suggest that in certain situations, AS frequency is reduced or transitioned to WW, yet decisions appear to be inconsistent and there are no significant barriers. These findings could inform further areas to explore when drafting recommendations that consider patients' values and preferences when making decisions about decreasing AS/converting to WW.

Project description:ObjectiveTo assess treatment related changes in quality of life up to 15 years after diagnosis of localised prostate cancer.DesignPopulation based, prospective cohort study with follow-up over 15 years.SettingNew South Wales, Australia.Participants1642 men with localised prostate cancer, aged less than 70, and 786 controls randomly recruited from the New South Wales electoral roll into the New South Wales Prostate Cancer Care and Outcomes Study (PCOS).Main outcome measuresGeneral health and disease specific quality of life were self-reported at seven time points over a 15 year period, using the 12-item Short Form Health Survey scale, University of California, Los Angeles prostate cancer index, and expanded prostate cancer index composite short form (EPIC-26). Adjusted mean differences were calculated with controls as the comparison group. Clinical significance of adjusted mean differences was assessed by the minimally important difference, defined as one third of the standard deviation (SD) from the baseline score.ResultsAt 15 years, all treatment groups reported high levels of erectile dysfunction, depending on treatment (62.3% (active surveillance/watchful waiting, n=33/53) to 83.0% (non-nerve sparing radical prostatectomy, n=117/141)) compared with controls (42.7% (n=44/103)). Men who had external beam radiation therapy or high dose rate brachytherapy or androgen deprivation therapy as primary treatment reported more bowel problems. Self-reported urinary incontinence was particularly prevalent and persistent for men who underwent surgery, and an increase in urinary bother was reported in the group receiving androgen deprivation therapy from 10 to 15 years (year 10: adjusted mean difference -5.3, 95% confidence interval -10.8 to 0.2; year 15: -15.9; -25.1 to -6.7).ConclusionsPatients receiving initial active treatment for localised prostate cancer had generally worse long term self-reported quality of life than men without a diagnosis of prostate cancer. Men treated with radical prostatectomy faired especially badly, particularly in relation to long term sexual outcomes. Clinicians and patients should consider these long term quality of life outcomes when making treatment decisions.

Project description:BackgroundThe routine clinical use of serum prostatic specific antigen (PSA) testing has allowed earlier detection of low-grade prostate cancer (PCa) with more favourable characteristics, leading to increased acceptance of management by active surveillance (AS). AS aims to avoid over treatment in men with low and intermediate-risk PCa and multiple governing bodies have described several AS protocols. This study provides a descriptive profile of the Guy's and St Thomas NHS Foundation Trust (GSTT) AS cohort as a platform for future research in AS pathways in PCa.MethodsDemographic and baseline characteristics were retrospectively collected in a database for patients at the GSTT AS clinic with prospective collection of follow-up data from 2012. Seven hundred eighty-eight men being monitored at GSTT with histologically confirmed intermediate-risk PCa, at least 1 follow-up appointment and diagnostic characteristics consistent with AS criteria were included in the profile. Descriptive statistics, Kaplan-Meier survival curves and multivariable Cox proportion hazards regression models were used to characterize the cohort.DiscussionA relatively large proportion of the cohort includes men of African/Afro-Caribbean descent (22%). More frequent use of magnetic resonance imaging and trans-perineal biopsies at diagnosis was observed among patients diagnosed after 2012. Those who underwent trans-rectal ultrasound diagnostic biopsy received their first surveillance biopsy 20 months earlier than those who underwent trans-perineal diagnostic biopsy. At 3 years, 76.1% men remained treatment free. Predictors of treatment progression included Gleason score 3 + 4 (Hazard ratio (HR): 2.41, 95% Confidence interval (CI): 1.79-3.26) and more than 2 positive cores taken at biopsy (HR: 2.65, CI: 1.94-3.62). A decreased risk of progressing to treatment was seen among men diagnosed after 2012 (HR: 0.72, CI: 0.53-0.98).ConclusionAn organised biopsy surveillance approach, via two different AS pathways according to the patient's diagnostic method, can be seen within the GSTT cohort. Risk of patients progressing to treatment has decreased in the period since 2012 compared with the prior period with more than half of the cohort remaining treatment free at 5 years, highlighting that the fundamental aims of AS at GSTT are being met. Thus, this cohort is a good resource to investigate the AS treatment pathway.
