【社会人文】适当的有氧运动可以使乳腺癌妇女
Women undergoing radiation treatment for breast cancer benefit from moderate intensity, regular aerobic activity, according to a new study. Published in the November 15, 2006 issue of CANCER (http://www.interscience.wiley.com/cancer-newsroom), a peer-reviewed journal of the American Cancer Society, the study found that exercise improved the oxygen capacity of patients and maintained levels of red blood cells during radiation treatment. In contrast, women who did not exercise experienced significant declines in their oxygen capacity. This is the first study to investigate the effect of exercise during treatment.
In the treatment of breast cancer, localized radiation therapy follows local surgical resection of the tumor. Its purpose is to destroy remaining cancer cells in and around the original tumor site. This combination is highly effective in this cancer's treatment.
Side effects from radiation therapy are mild to moderate, ranging from a sunburn to an increased risk for cancer of the muscle or a sarcoma. Radiation also causes fatigue, anemia and depression soon after therapy is initiated. These symptoms are often associated with laboratory findings of reduced circulating red blood cells and hemoglobin, the means of oxygen transport in the body.
Studies have shown that physical rehabilitation following the completion of therapy effectively resolves the fatigue and anemia. However, to date there have been no studies investigating the effect of exercise on red blood cells. Led by Jacqueline S. Drouin, P.T., Ph.D. of the School of Health Professions and Studies at the University of Michigan-Flint, researchers compared the impact of exercise versus no exercise during radiotherapy on red blood cell levels and on maximum oxygen capacity, a measure of physical fitness, in 20 women with breast cancer.
The authors found that compared to women who did not regularly exercise, women who briskly walked 20-45 minutes three to five times a week during radiotherapy treatment did not experience a decline in levels of hemoglobin, red blood cells, and hematocrit. In the aerobic exercise group, mean red blood cell levels increased slightly while they declined in the sedentary group. Similarly, hemoglobin levels slightly increased while they fell in the sedentary group.
In addition, increases in these red blood cell measures also significantly correlated with increases in peak oxygen capacity.
"Study results support the potential for moderate aerobic exercise to be a safe, effective, and economical method for improving physical fitness and maintaining erythrocyte levels in females undergoing radiation treatment for breast cancer," conclude the authors.

根据发表在《癌症》杂志2006年11月15日上的一项新的研究发现：因乳腺癌经放射治疗的女性，可以从中等强度有规律的有氧运动中获益。这项研究发现运动可改善患者的氧摄取能力并放疗期间的红细胞水平。相反，没有进行运动的女性其氧摄取能力明显。这首次探讨了运动在乳腺癌治疗过程中的作用。

在乳腺癌治疗中，经外科手术切除局部肿瘤后，常进行定位放疗，其目的是尽量破坏局部和周围的残存肿瘤细胞。这种联合治疗方式在乳腺癌的治疗中非常有效。

与放疗有关的副作用一般从轻微到中等，从轻微灼伤到发生肌肉恶性肿瘤（肉瘤）的较高危险。放疗开始后不久可出现、贫血和抑郁等，这些症状通常伴随实验室指标如周围血红细胞、血红蛋白的下降，使机体运输氧的能力降低。
