Purpose/Objective:

Oligometastatic prostate cancer patients often participate in shared decision-making to select a treatment regimen from multiple options. However, dissatisfaction with treatment outcomes may lead to decision regret. We evaluated decision regret and physical and psychological well-being among oligometastatic cancer patients who underwent radiotherapy and explored associations with patient, tumor, and treatment characteristics and symptoms.

Material/Methods:

This cross-sectional study involved retrospectively obtaining clinical data and data collected through interviews carried out within regular long-term medical aftercare. Decision regret was assessed using the Ottawa Decision Regret Scale, physical and psychological well-being were assessed using the PROMIS Global Health-10 questionnaire, and patients were also asked about their treatment outcomes and symptoms. The questionnaire was administered 8 months to 10 years after completion of radiotherapy.

Results:

Of the 241 included oligometastatic prostate cancer patients, only 10.9% expressed high decision regret, with most patients expressing little or no decision regret. More decision regret was associated with volumetric modulated arc therapy, irradiation of the lymphatics, use of chemohormonal therapy with docetaxel, visceral metastasis, urinary incontinence, and lower psychological well-being.

Conclusion:

Although most patients reported little or no decision regret, our findings identify several treatment characteristics that are associated with more decision regret. Our findings also suggest that psychological well-being influences patients’ satisfaction with therapy decisions, implying that practitioners should pay special attention to maintaining psychological well-being during shared decision-making and ensuring that psychological assessment and treatment is provided after cancer therapy to deal with the long-term effects of radiotherapy.
