Low conflict and high satisfaction: Decisional outcomes after attending a combined clinic to choose between robotic prostatectomy and radiotherapy for prostate cancer

Urol Oncol. 2021 Jun 8:S1078-1439(21)00213-1. doi: 10.1016/j.urolonc.2021.05.007. Online ahead of print.


BACKGROUND: Decisional conflict and post-treatment decisional regret have been documented in men with localised prostate cancer (LPC). However, there is limited evidence regarding decisional outcomes associated with the choice between robotic-assisted radical prostatectomy (RARP) and radiotherapy, when both treatment options are available in the public health system. There is increasing support for multidisciplinary approaches to guide men with LPC in their decision-making process. This study assessed decisional outcomes in men deciding between RARP or radiotherapy treatment before and after attending a LPC combined clinic (CC).

METHODS: Quantitative longitudinal data were collected from 52 men who attended a LPC CC, where they saw both a urologist and radiation oncologist. Patients completed questionnaires assessing involvement in decision-making, decisional conflict, satisfaction and regret before and after the CC, three months, six months and 12 months post-treatment. Urologists and radiation oncologists also reported their perceptions regarding patients’ suitability for, openness to, perceived preferences and appropriateness for each treatment. Data was analysed using paired/independent samples t-tests and McNemar’s tests.

RESULTS: Most participants (n = 37, 71%) opted for RARP over radiotherapy (n = 14, 27%); one participant deferred treatment (2%). Urologists and radiation oncologists reported low agreement (κ = 0.26) regarding the most appropriate treatment for each patient. Participants reported a desire for high levels of control over their decision-making process (77.5% patient-led, 22.5% shared) and high levels of decisional satisfaction (M = 4.4, SD = 0.47) after the CC. Decisional conflict levels were significantly reduced (baseline: M = 29.3, SD = 16.9, post-CC: M = 16.3, SD = 11.5; t = 5.37, P < 0.001) after the CC. Mean decisional regret scores were ‘mild’ at three-months (M = 16.0, SD = 17.5), six-months (M = 18.8, SD = 18.7) and 12-months (M = 18.2, SD = 15.1) post-treatment completion.

CONCLUSION: This is the first Australian study to assess decisional outcomes when patients are offered the choice between RARP and radiotherapy in the public health system. A CC seems to support decision-making in men with LPC and positively impact some decisional outcomes. However, larger-scale controlled studies are needed to confirm these findings.
