睡眠影响癌症患者的生存率？

  最近，来自华盛顿大学研究人员的一项最新研究显示，诊断前短时间睡眠和频繁打鼾或许和癌症特异性的存活率较差明显相关，尤其是对于乳腺癌女性而言。
  研究者Amanda Phipps教授表示，我们的研究结果表明，睡眠持续时间对于乳腺癌患者的存活率非常重要，尤其是睡觉打鼾的女性；相关研究于近日刊登于国际杂志Sleep上。文章中研究者通过对不同癌症进行研究，发现较短的睡眠时间以及频繁打鼾或许会明显影响癌症患者的存活率，在患乳腺癌的女性患者机体中表现尤为明显。
  这项研究中，研究人员对21230名女性患者进行追踪研究，这些患者都被诊断为原发性侵袭性癌症，参与者均提供了她们的睡眠相关的一些数据，包括睡眠持续时间、打鼾以及其它相关的信息，随后研究人员对参与者的相关信息进行了调整，比如招募年龄、患者的癌症部位、婚姻状况、家庭收入、吸烟情况、体力劳动以及癌症诊断等相关数据。
  最后研究者表示，通过我们研究发现睡眠持续时间以及睡眠质量和癌症患者的生存率存在着直接的关系，后期我们还将开展更为深入的研究来阐明睡眠为何会影响癌症患者的生存率，从而为开发相应的干预措施或疗法来有效缓解患者的病情及改善患者的生活质量提供一定的帮助和希望。（转化医学网360zhyx.com）

Sleep duration, quality may impact cancer survival rate
Results show that stratified by cancer site, short sleep duration and frequent snoring were associated with significantly poorer breast cancer-specific survival.

"Our results suggest that sleep duration is important for breast cancer survival, particularly in women who snore," said lead author Amanda Phipps, assistant professor of epidemiology at the University of Washington in Seattle, Wash. and assistant member at the Fred Hutchinson Cancer Research Center.

The research abstract was published recently in an online supplement of the journal Sleep and will be presented Wednesday, June 10, in Seattle, Washington, at SLEEP 2015, the 29th annual meeting of the Associated Professional Sleep Societies LLC.

The study group comprised of 21,230 women diagnosed with a first primary invasive cancer during follow-up from the Women's Health Initiative (WHI). Participants provided information on several sleep attributes at study baseline, including sleep duration, snoring, and components of the WHI Insomnia Rating Scale. Analyses were adjusted for age at enrollment, study arm, cancer site, marital status, household income, smoking, physical activity, and time-lag between baseline data collection and cancer diagnosis.
