美国丹纳法伯癌症研究所一项研究显示，有规律的适量运动可以降低大肠癌患者的死亡率。相关研究发表在近期出版的《美国内科学文献》杂志上。
丹纳法伯癌症研究所医学和公共卫生学博士杰弗里·梅耶哈德说，先前就有研究表明，有规律的运动可以减少患结肠癌的风险。而其最近的研究发现，良好的运动习惯还可以提高大肠癌患者的存活率。
梅耶哈德和他的团队对668名患有大肠癌的男性进行了研究。其中有一半的人在每周至少有6天的时间会进行运动，每次的运动量大约相当于步行一小时。研究人员发现，经常运动的患者的存活率和治愈率比那些极少运动的患者要高53%。另外，运动的益处并不受年龄、体重以及运动史等因素的限制。
梅耶哈德称，目前适量运动已成为不少大肠癌幸存者的“秘诀”，他们的调查表明，规律运动对大肠癌患者而言是值得考虑的选择。但还应该注意的是，运动只是传统治疗方法的一个有益补充，并不能将标准疗法取而代之。（生物谷Bioon.com）

Background Although physically active individuals have a lower risk of developing colorectal cancer, few studies have examined whether exercise benefits colorectal cancer survivors.
Methods Derived from the Health Professionals Follow-up Study, we studied colorectal cancer–specific and overall mortality in a cohort of 668 men with a history of stage I to stage III colorectal cancer according to predefined physical activity categories after diagnosis. To minimize bias by occult recurrences, we excluded men who died within 6 months of their postdiagnosis physical activity assessment.
Results In a cohort of men with colorectal cancer and no apparent metastases at diagnosis, 50.4% exercised at least 18 metabolic equivalent task (MET) hours per week. Increased physical activity was significantly associated with improved colorectal cancer–specific mortality (P = .002 for trend) and overall mortality (P < .001 for trend). Men who engaged in more than 27 MET hours per week of physical activity had an adjusted hazard ratio for colorectal cancer–specific mortality of 0.47 (95% confidence interval, 0.24-0.92) compared with men who engaged in 3 or less MET hours per week of physical activity. The apparent benefit of physical activity was seen regardless of age, disease stage, body mass index, diagnosis year, tumor location, and prediagnosis physical activity.
Conclusion In a large cohort of men with a history of nonmetastatic colorectal cancer, more physical activity was associated with a lower risk of colorectal cancer–specific and overall mortality.
