Cancer-associated cognitive decline is a concern among cancer survivors. Survivors' memory lapses (eg, location of keys, names, and reason entered room) may negatively impact quality of life. This study used smartphone-based surveys to compare cancer survivors to those without cancer history on frequency of, severity of, and affective response to daily memory lapses.
For 14 evenings, breast cancer survivors (N = 47, M age = 52.9) and women without a cancer history (N = 105, M age = 51.8) completed smartphone-based surveys on memory lapse occurrence and severity and negative and positive affect.
Survivors were nearly three times more likely to report a daily memory lapse but did not differ from comparison group on memory lapse severity. Negative affect was significantly higher on days with memory lapses associated with doing something in the future (eg, appointments) but this did not differ across groups. Positive affect was not significantly related to survivorship status or the occurrence of daily memory lapses.
Survivors may be at-risk for more frequent memory lapses. Both survivors and women without a history of cancer reported greater negative affect on days when memory lapses occurred, suggesting that daily cognitive functioning may have important implications for quality of life.
癌症相关认知衰退是癌症幸存者关注的问题。幸存者的记忆失误（例如，钥匙、名字和进入房间的原因的位置）可能会对生活质量产生负面影响。本研究使用基于智能手机的调查，比较了癌症幸存者和无癌症病史者日常记忆失误的频率、严重程度和情感反应。
在 14 个晚上，乳腺癌幸存者（N=47，平均年龄=52.9）和无癌症病史的女性（N=105，平均年龄=51.8）使用智能手机完成了关于记忆失误发生和严重程度以及负面和正面情绪的调查。
幸存者每天报告记忆失误的可能性几乎是对照组的三倍，但记忆失误的严重程度与对照组无差异。与未来（例如约会）有关的记忆失误时，负性情绪显著更高，但两组之间没有差异。正性情绪与生存状态或日常记忆失误的发生没有显著关系。
幸存者可能更容易出现记忆失误。幸存者和无癌症病史的女性在记忆失误发生时都报告了更高的负性情绪，这表明日常认知功能可能对生活质量有重要影响。
