摘要

摘要癌症患者自杀行为的风险增加。众所周知，自杀呈季节性，在春季和初夏达到高峰，这表明大约每年都有环境因素的影响。在这里，我们质疑癌症诊断是否与自杀的季节性相互作用。我们在监测、流行病学和最终结果（SEER）数据库中对1974年至2016年间注册的癌症患者自杀的季节性进行了回顾性分析，符合经典的余弦模型。确定了一个显著的季节性模式，其峰值出现在5月上半月。在两性以及老年人（＞50岁）和白人患者中都观察到了相同的峰值。与来自北方各县的患者相比，生活在南方各县的病人峰值更早。早期（诊断后第一年内）和晚期自杀率也遵循相同的季节模式，5月达到峰值。对癌症亚型的分析显示，只有癌症患者在5月达到显著峰值。我们的研究结果表明，癌症诊断不会改变普通人群中观察到的典型季节性自杀模式。因此，癌症患者的心理支持必须在春季和初夏特别积极。

Seasonality of Suicides among Cancer Patients

ABSTRACT Cancer patients are at increased risk of suicidal behavior. It is well known that suicides show seasonality with peak in the Spring and early Summer suggesting the influence of circa-annual environmental factors. Here we questioned whether cancer diagnosis interacts with the seasonality of suicides. We performed a etrospective analysis of seasonality of suicides among cancer patients registered between 1974 and 2016 in the Surveillance, Epidemiology, and End Results (SEER) database fitting the classical cosinor model . A significant seasonal pattern with a peak in the first half of May was identified. The same peak was observed for both sexes as well as for elderly (> 50 years) and White patients. Patients living in Southern counties had an earlier peak versus those from Northern counties. The rate of both early (within the first year after diagnosis) and late suicides also followed the identical seasonal pattern with peak in May. The analysis per cancer subtypes revealed that only prostate cancer patients had a significant peak in May. Our findings suggest thatcancer diagnosis does not alter the typical seasonal pattern of suicides observed in the general population. Therefore, psychological support in cancer patients must be particularly active in the Spring and early Summer.

期刊介绍： The principal aim of Biological Rhythm Research is to cover any aspect of research into the broad topic of biological rhythms. The area covered can range from studies at the genetic or molecular level to those of behavioural or clinical topics. It can also include ultradian, circadian, infradian or annual rhythms. In this way, the Editorial Board tries to stimulate interdisciplinary rhythm research. Such an aim reflects not only the similarity of the methods used in different fields of chronobiology, but also the fact that many influences that exert controlling or masking effects are common. Amongst the controlling factors, attention is paid to the effects of climate change on living organisms. So, papers dealing with biometeorological aspects can also be submitted. The Journal publishes original scientific research papers, review papers, short notes on research in progress, book reviews and summaries of activities, symposia and congresses of national and international organizations dealing with rhythmic phenomena.
