近年来,有关肥胖和肿瘤的关系研究得越来越多。比如乳腺癌 http://blog.wenxuecity.com/myblog/69489/201612/1618849.html ,肠癌,子宫内膜癌,
有人尝试用改变饮食习惯和结构的方式来治疗癌症。
那么肥胖和血液肿瘤有相关性吗? 在2007年发表在权威的《临床肿瘤杂志》Journal of Clinical Oncology 上,一组研究人员收集了从1988-1995年的343例肥胖,
有趣的是,最近一群在德州(UT Southwestern Medical Center) 的华人学者,在顶级医学刋物巜Nature Medicine》上发表了一篇用饥饿(fasting)
研究者制造了几个老鼠的急性白血病模型,
研究发现,间隙性一天禁食和一天进食,
看来,形势逼人,又多了一个与饮食/肥胖和肿瘤关系的模型!

应该说,这个重大研究目前仅在动物模型阶段。在人体呢? 大家去推测吧。

The 1988 to 1995 cohort included 343 obese and 3,971 nonobese patients. The 5-year event-free survival rate and risk of relapse, in Conclusion : Obesity at diagnosis independently predicts likelihood of relapse and cure in preteenagers and adolescents with ALL.
