非小细胞肺癌大分割放疗

Hypofractionated radiotherapy for non-small-cell lung cancer

大分割三维适形放疗（3DCRT）为进一步改善非小细胞肺癌（NSCLC）患者局部控制率、生存率及生活质量提供了可能，但最佳剂量分割方案尚不明确，有待进一步研究。立体定向体部放疗（SBRT）在早期NSCLC中取得了令人满意的局部控制率和生存率，且不良反应在可接受的范围内，有望成为早期NSCLC患者新的标准治疗手段。

Hypofractionated three-dimensional conformal radiotherapy （3DCRT） makes it possible to further improve local control, overall survival and the quality of life for the patients with non-small-cell lung cancer （NSCLC）. But the dose-fraetionation and total dose are not yet clear, which need further study. Hypo- fractionated stereotactic body radiotherapy （SBRT） for early-stage NSCLC patients is well tolerated and results in excellent local control and overall survival. SBRT is expected to become a new standard treatment in patients with early stage NSCLC.
