胸廓切开术

PET-CT also reduced the total number of thoracotomies and improved diagnostic accuracy compared with conventional staging.

PET-CT也比传统分期降低整体胸廓切开术的次数，改善诊断准确度。

The study was designed so that 215 patients would be randomized to each group (for a total of 430 patients), thus allowing enough power to detect a difference of 15% in the number of futile thoracotomies between the 2 groups, write the authors.

作者们写道，该研究原本希望每组病患有215人(总共430人进行随机分组)，才可以有足够的强度发现两组之间无效的胸廓切开术数量有15%的差异。

PET-CT also reduced the total number of thoracotomies and improved diagnostic accuracy compared with conventional staging.

PET-CT也比传统分期降低整体胸廓切开术的次数，改善诊断準确度。

July 1, 2009 — The frequency of futile thoracotomies is reduced by use of combined positron-emission tomography and computed tomography compared with conventional staging in patients with non–small-cell lung cancer, according to a new study.

July 1， 2009 —根据一篇新研究，相较於非小细胞肺癌的传统分期，併用正子放射断层造影术与电脑断层可以降低无效的胸廓切开术频率。

Randomized trials evaluating the utility of PET in potentially resectable NSCLC report conflicting results in terms of the relative reduction in the number of noncurative thoracotomies.

由于姑息性的胸廓切开术相对数量较少，对于 PET 在可切除 NSCLC 患者中使用的随机试验评估存在着矛盾的结论。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
