摘要目的 评价冷冻消融(CA)对放化疗失败后非小细胞肺癌(NSCLC)进行挽救性治疗的有效性和安全性.方法 2005年2月至2008年9月天津医科大学附属肿瘤医院介入治疗科12例接受放化疗后进展或复发的Ⅲ期NSCLC患者接受挽救性CA治疗.研究的终点目标是总反应率(RR)、临床受益率(CBR)、1年生存率、生活质量(QOL)以及安全性等.结果 CA治疗组12例可评价疗效的患者中,术后12个月,总RR率为6/12例,CBR 7/12例,1年生存率为10/12例,不良反应主要包括术后术区不适感及轻度咯血,无严重不良事件发生.生活质量评分结果证实患者可获得较好的生活质量.结论 CA挽救性治疗放化疗失败的NSCLC可获得较高的RR及1年生存率且安全性较好,是Ⅲ期NSCLC挽救性治疗的新选择,具有较好的临床应用前景.

abstractsObjective To evaluate the efficacy and safety of argon-helium cryoablation as a salvage therapy for the failure cases of non-small cell lung cancer (NSCLC) after radiochemotherapy. Methods A total of 12 NSCLC patients ( stage Ⅲ ) with a diagnosis of recurrence after radiochemotherapy received cryoablation. The endpoint objectives were overall response rate ( RR), clinical benefit rate ( CBR), 1-year survival rate, quality of life (QOL) and safety profile. Results Among them, the overall response rate was 6/12 cases and the clinical benefit rate 7/12 cases at 12 months post-cryoablation. The 1-year survival rate was 10/12 cases. No significant complications or adverse reactions occurred during the process of cryoablation. As shown by the QOL score, the quality of life was satisfactory. Conclusion As a salvage treatment for the recurrence NSCLC cases after radiochemotherapy, cryoablation may achieve a high response rate, a favorable 1-year survival rate and a high safety profile. It has excellent prospects for clinical applications.
