Quality of life (QOL) has rarely been assessed in nonmetastatic bladder cancer patients (NMBC). Therefore, very little information is available for comparing the impact of different treatments on QOL for patients affected by NMBC.
We developed an "ad hoc" self-administered questionnaire and evaluated its psychometric properties. We then carried out a retrospective study by mailing the questionnaire to a consecutive series of 93 patients treated for NMBC between 1981 and 1994. The patients were treated either with a conservative approach (CT), based on radiotherapy with or without chemotherapy, or with cystectomy followed by urostomy (US).
Twenty-nine questionnaires (66%) mailed to conservatively treated patients and 30 (61%) mailed to cystectomized patients were returned. The questionnaire used in the study showed sufficient psychometric properties: an alpha-Cronbach coefficient > 0.8 was reached and validity was established in all of its aspects. The items were grouped into seven subscales reflecting different QOL domains. The two treatment groups reported differences in QOL adjustment. QOL after cystectomy, marked by stoma presence, was reduced by a lack of sexual activity and a worsened physical condition, but social and recreational life were little affected. Conversely, a low incidence of urinary symptoms and an acceptable sexual adjustment were found in the CT sample; the physical, psychologic, and sociorelational adjustments were also good. QOL in the CT group was consistently better than in the US group. All subscale scores were higher in the CT group than in the US group, with a statistically significant difference in four of six subscales.
QOL is better after conservative therapy than after cystectomy, as expected. Prospective studies with repeated measurements covering all fields of interest in QOL would offer an accurate assessment of QOL in NMBC patients.
非转移性膀胱癌患者(NMBC)的生活质量(QOL)很少得到评估。因此,关于比较不同治疗方法对NMBC患者生活质量影响的信息非常少。
我们编制了一份“特设”自填式问卷,并评估了其心理测量特性。然后,我们通过将问卷邮寄给1981年至1994年间连续接受治疗的93例NMBC患者进行了一项回顾性研究。患者接受了基于放疗加或不加化疗的保守治疗(CT),或膀胱切除术后行尿路造口术(US)。
寄给接受保守治疗患者的29份问卷(66%)和寄给膀胱切除患者的30份问卷(61%)被收回。研究中使用的问卷显示出足够的心理测量特性:α-克朗巴赫系数>0.8,并且在各个方面都建立了有效性。这些项目被分为七个反映不同生活质量领域的子量表。两个治疗组在生活质量调整方面存在差异。膀胱切除术后的生活质量因造口的存在而受到影响,缺乏性活动和身体状况恶化使其降低,但社会和娱乐生活受影响较小。相反,在CT样本中发现泌尿症状发生率低且性调整可接受;身体、心理和社会关系调整也良好。CT组的生活质量始终优于US组。CT组所有子量表得分均高于US组,六个子量表中有四个存在统计学显著差异。
正如预期的那样,保守治疗后的生活质量比膀胱切除术后更好。对生活质量所有感兴趣领域进行重复测量的前瞻性研究将为NMBC患者的生活质量提供准确评估。
