NEW YORK (Reuters Health) - Both exercise therapy and psychological counseling might offer some relief from the fatigue that often plagues cancer patients, a new research review suggests.
纽约（路透社健康）一个新的研究评论指出，锻炼治疗和心理咨询都可能减轻经常折磨癌症患者的疲劳。

In an analysis of 41 clinical trials, researchers found that when they combined the results of the studies, both counseling and exercise seemed to be modestly effective in battling cancer-related fatigue.
在一个对41个临床实验的分析中，研究者发现当他们将这些研究结果结合起来分析时，咨询和锻炼在对抗癌症相关疲劳方面都有一定的效果。

Past studies have shown that fatigue is one of the biggest drains on cancer patients' quality of life. It's not clear, however, how to best address the problem; fatigue may result from the cancer itself or the therapies used to treat it, and factors such as patients' lifestyle and emotional well-being can exacerbate fatigue.
之前的研究显示，疲劳是降低癌症病人生活品质的最大因素之一。然而并不清楚如何解决这个问题。疲劳可能由癌症疾病本身引起，也可能由针对癌症的治疗方法引起的。患者的生活方式和情绪好坏等因素也能使疲劳加剧。

Several small studies have suggested that exercise therapy, such as specially designed yoga classes, might help cancer patients feel more energized. Similarly, some research suggests that psychological help -- group therapy or even over-the-phone counseling -- aids fatigue.
几个小型研究指出，锻炼疗法，比如特别设计的瑜伽课程，可能会使癌症患者感觉更加精力充沛。而相似地，另一些研究显示，心理上的帮助，如团体治疗甚至电话咨询，也对减少疲劳有所帮助。

For the new study, researchers tried to get an overall view of the evidence by combining the results of many of these previous studies. Overall, the results provide "limited support" for using exercise or psychological therapy to relieve cancer fatigue, they report in the journal Health Psychology.
在这项新的研究中，研究者尝试着通过结合众多之前研究的结果，从而获得对相关证据的全面观点。他们在《健康心理学》杂志中报告说，就整体而言，这些结果表明使用锻炼或心理治疗方法来减少癌症相关疲劳只能产生“有限的帮助”。

The evidence is limited, in part, because many clinical trials suffered from design flaws, and of those the researchers rated as better-quality, only about half showed benefits from counseling or exercise.
从某种程度上来说证据是有限的，因为很多临床试验的设计都有缺陷。而在被研究者认为质量较高的研究中，只有约一半显示咨询和锻炼能缓解癌症相关疲劳。

"The overall effects of both psychological and activity-based interventions on fatigue were modest," lead researcher Dr. Paul Jacobsen, of the H. Lee Moffitt Cancer Center in Tampa, Florida, said in a statement.
首席研究员来自佛罗里达坦帕Lee Moffitt 癌症研究中心的Paul Jacobsen博士，在一份声明中说，“对疲劳进行心理和运动治疗的整体效果是有限的。”。

However, he added that, at least in the studies of psychological counseling, the benefits were strong enough that they there were unlikely to be due to chance.
然而，他补充说，至少在对心理咨询的研究中，其产生的好处已足以使得它们不至于被归因于偶然。

For cancer patients who are interested in trying exercise to aid fatigue, Jacobsen urged that they use caution.
对于热衷于通过锻炼来减轻疲劳的癌症病人，Jacobsen规劝他们保持谨慎。

"Patients should consult with their physicians before initiating an exercise regimen," he said. "They should also let their physician know if they plan to continue to engage in regular exercise while undergoing taxing treatments like chemotherapy."
“病人应该在开始锻炼养身前咨询他们的医生，”他说，“他们如果计划在实施消耗较大的治疗方法如化疗时继续进行常规锻炼，也应该让医生知道。”
