To assess factors that may influence men's preference for surgery versus nonsurgical options among newly diagnosed patients considering treatments for local-stage prostate cancer.
Prostate cancer patients were approached at urology clinics after diagnosis but prior to starting treatment in California, South Carolina, and Texas. Using a survey about the treatment decision-making process, patients were asked about their likes and dislikes of 5 common treatment options: surgery (prostatectomy), brachytherapy, external beam radiation therapy, hormone therapy, and watchful waiting.
Logistic regression identified associations between treatment characteristics and choice of prostatectomy compared with nonsurgical options, controlling for demographic, clinical, and psychological covariates.
Of the 198 eligible men who returned the baseline survey, 59% indicated they only considered surgery and 41% considered at least 1 nonsurgical option. In multivariate analysis, patients who thought treatment efficacy was a primary concern were significantly more likely to prefer surgery only (odds ratio [OR] = 6.20, 95% confidence interval [95% CI] = 1.74, 22.10); those indicating concern about personal burden were significantly more likely to prefer nonsurgical options (OR = 0.07, 95% CI = 0.02, 0.22). Advice of friends and relatives and concerns over side effects were not significantly associated with preference for surgery versus other treatments.
Men's perceptions about treatment efficacy and the personal burden of treatment dominated preferences for surgery versus nonsurgical options. Interventions to aid treatment decision making should account for these elements to minimize the impact of physician biases and patient misperceptions on men's decisions as how best to manage their prostate cancer.
评估可能影响新诊断为局部前列腺癌患者对手术与非手术治疗选择偏好的因素。
在加利福尼亚州、南卡罗来纳州和德克萨斯州,在泌尿科诊所对诊断后但在开始治疗前的前列腺癌患者进行了研究。使用关于治疗决策过程的调查,患者被问及他们对 5 种常见治疗选择(手术[前列腺切除术]、近距离放射治疗、外束放射治疗、激素治疗和观察等待)的喜好。
逻辑回归确定了治疗特征与与非手术治疗选择相比的前列腺切除术选择之间的关联,控制了人口统计学、临床和心理协变量。
在 198 名符合条件的返回基线调查的男性中,59%表示他们只考虑手术,41%考虑了至少 1 种非手术选择。在多变量分析中,认为治疗效果是主要关注点的患者更有可能只选择手术(优势比[OR] = 6.20,95%置信区间[95%CI] = 1.74,22.10);表示担心个人负担的患者更有可能选择非手术治疗(OR = 0.07,95%CI = 0.02,0.22)。朋友和亲戚的建议以及对副作用的担忧与对手术与其他治疗的偏好没有显著关联。
男性对治疗效果和治疗个人负担的看法主导了对手术与非手术治疗选择的偏好。为了帮助治疗决策,应考虑这些因素,以最大限度地减少医生偏见和患者误解对男性如何最好地管理前列腺癌的决策的影响。
