Brain metastases are a significant cause of morbidity and mortality for patients with advanced cancers, and quality-of-life (QoL) end points are most appropriate for this population. The Functional Assessment of Cancer Therapy (FACT) questionnaires are commonly used to assess cancer-related QoL issues. The FACT-Brain (FACT-Br) provides an additional set of disease-specific questions pertaining to brain neoplasms. We aim to provide a comprehensive review to examine the use of the FACT-Br as a QoL assessment for patients with brain metastases.
MATERIALS & METHODS: A review of the literature was conducted and all studies utilizing the FACT-Br for QoL assessment of patients with brain metastases were included. Study information and relevant information regarding the FACT-Br were extracted.
A total of 14 studies were identified representing various treatment options (radiation, chemotherapy and surgery) for patients with brain metastases. All studies utilized at least part of the FACT-Br as the main QoL assessment. In addition, neurocognitive and performance status assessments were performed in nine and 12 out of 14 studies, respectively. Issues of poor accrual, compliance and attrition were common and posed problems in reaching statistically significant changes in QoL despite changes in raw QoL scores.
Studies involving patients with brain metastases should continue to utilize QoL tools such as the FACT-Br; however, this tool still requires validation for use in this patient population. Additional studies should observe the relationship between neurocognitive function and QoL, and attempt to minimize poor accrual and compliance issues through modifications of trial design and reduction of patient burden.
脑转移是晚期癌症患者发病率和死亡率的重要原因,生活质量(QoL)终点最适合该人群。功能评估癌症治疗(FACT)问卷通常用于评估癌症相关的 QoL 问题。FACT-脑(FACT-Br)提供了一组与脑肿瘤相关的特定疾病问题。我们旨在进行全面审查,以检查 FACT-Br 作为脑转移患者 QoL 评估的使用情况。
对文献进行了回顾,所有使用 FACT-Br 评估脑转移患者 QoL 的研究均被纳入。提取了研究信息和与 FACT-Br 相关的信息。
共确定了 14 项研究,代表了脑转移患者的各种治疗选择(放疗、化疗和手术)。所有研究均至少使用了 FACT-Br 的一部分作为主要的 QoL 评估。此外,在 9 项和 12 项研究中分别进行了神经认知和表现状态评估。尽管 QoL 评分发生了变化,但入组、依从性和流失率等问题仍然普遍存在,这给 QoL 变化的统计学意义带来了问题。
涉及脑转移患者的研究应继续使用 FACT-Br 等 QoL 工具;然而,该工具仍需要在该患者人群中进行验证。应进一步研究神经认知功能与 QoL 之间的关系,并尝试通过修改试验设计和降低患者负担来最小化入组和依从性问题。
