摘要
目的:探讨三维适形放疗(3-dimensional conformal radiotherapy,3D-CRT)大分割放射治疗早期非小细胞肺癌的疗效和毒性反应。方法:11例早期非小细胞肺癌(I期8例,IIB期3例;中位年龄72岁)三维适形大分割放射治疗(hypofractionation radiotherapy,HORT)全程或后程推量,肿瘤剂量60Gy^76Gy,3Gy^8Gy/次,1次/天,3次~5次/周。生物等效剂量76.8Gy^105.6 Gy。中位随访时间54个月。根据WHO标准评价近期疗效,RTOG标准评价毒性反应。结果:完全缓解(CR)9.09%(1/11),部分缓解(PR)81.8%(9/11),稳定(NC)9.09%(1/11)。中位生存时间39个月。1,3及5年总生存率分别为81.8%,58.4%和18%,1,3及5年肿瘤相关生存率分别为91%,91%和18%。放射性食管炎27.3%(2级2例,3级1例),急性放射性肺炎(2级1例)9.09%。结论:三维适形大分割放射治疗早期非小细胞肺癌近期疗效和生存率优于常规分割放疗,放疗毒性未见明显增加,耐受性好,是一种有效安全的局部治疗手段。
Objective: To evaluate the effect and toxicity of HORT for early-stage NSCLC. Methods: 11 patients (Medi- urn age 72 years,8 stage 1,3 stage IIB) with early-stage non-small-cell lung cancer were treated by HORT. A total dose of 60-76Gy,3- 8Gy/f/d,3-Sf/wwas received. Results: The response rate (CR+PR) wasg0.9%, including (CR) 9.09% (1/11) and (PR) 81.8 % (9/11). The medium survival time was 39 monthes. The 1,3,5y overall survival rate (OSR) were 81.8%, 58.4%, and 18% respectively. And the 1,3,5y disease-specific survival rate(DSS) were 91% ,91%, and 18% respectively. Conclusion: The HORT for early-stage NSCLC had satisfying response. The radiation toxicity of HORT was tolerable. HORT is one of safe and effective local treatments.
