美國(guó)丹納法伯癌癥研究所一項(xiàng)研究顯示，有規(guī)律的適量運(yùn)動(dòng)可以降低大腸癌患者的死亡率,。相關(guān)研究發(fā)表在近期出版的《美國(guó)內(nèi)科學(xué)文獻(xiàn)》雜志上,。
丹納法伯癌癥研究所醫(yī)學(xué)和公共衛(wèi)生學(xué)博士杰弗里·梅耶哈德說(shuō)，先前就有研究表明,，有規(guī)律的運(yùn)動(dòng)可以減少患結(jié)腸癌的風(fēng)險(xiǎn),。而其最近的研究發(fā)現(xiàn)，良好的運(yùn)動(dòng)習(xí)慣還可以提高大腸癌患者的存活率,。
梅耶哈德和他的團(tuán)隊(duì)對(duì)668名患有大腸癌的男性進(jìn)行了研究,。其中有一半的人在每周至少有6天的時(shí)間會(huì)進(jìn)行運(yùn)動(dòng)，每次的運(yùn)動(dòng)量大約相當(dāng)于步行一小時(shí),。研究人員發(fā)現(xiàn),，經(jīng)常運(yùn)動(dòng)的患者的存活率和治愈率比那些極少運(yùn)動(dòng)的患者要高53%。另外,，運(yùn)動(dòng)的益處并不受年齡,、體重以及運(yùn)動(dòng)史等因素的限制。
梅耶哈德稱,，目前適量運(yùn)動(dòng)已成為不少大腸癌幸存者的“秘訣”,，他們的調(diào)查表明，規(guī)律運(yùn)動(dòng)對(duì)大腸癌患者而言是值得考慮的選擇,。但還應(yīng)該注意的是,，運(yùn)動(dòng)只是傳統(tǒng)治療方法的一個(gè)有益補(bǔ)充，并不能將標(biāo)準(zhǔn)療法取而代之,。（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.
