The purpose was to assess the feasibility and efficacy of hyperfractionated accelerated radiotherapy (HART) after induction chemotherapy for Stage III non-small-cell lung cancer.
Treatment consisted of 2 cycles of cisplatin 80 mg/m(2) on Day 1 and vinorelbine 25 mg/m(2) on Days 1 and 8 every 3 weeks followed by HART, 3 times a day (1.5, 1.8, 1.5 Gy, 4-h interval) for a total dose of 57.6 Gy.
Thirty patients were eligible. Their median age was 64 years (range, 46-73 years), 24 were male, 6 were female, 8 had performance status (PS) 0, 22 had PS 1, 9 had Stage IIIA, and 21 had Stage IIIB. All but 1 patient completed the treatment. Common grade > or =3 toxicities during the treatment included neutropenia, 25; infection, 5; esophagitis, 5; and radiation pneumonitis, 3. The overall response rate was 83%. The median survival was 24 months (95% confidence interval [CI], 13-34 months), and the 2-year overall survival was 50% (95% CI, 32-68%). The median progression-free survival was 10 months (95% CI, 8-20 months).
Hyperfractionated accelerated radiotherapy after induction of cisplatin and vinorelbine was feasible and promising. Future investigation employing dose-intensified radiotherapy in combination with chemotherapy is needed.
评估诱导化疗后超分割加速放疗(HART)用于Ⅲ期非小细胞肺癌的可行性和疗效。
治疗包括每3周进行2个周期的顺铂80mg/m²(第1天)和长春瑞滨25mg/m²(第1天和第8天),随后进行HART,每天3次(1.5、1.8、1.5Gy,间隔4小时),总剂量为57.6Gy。
30例患者符合条件。他们的中位年龄为64岁(范围46 - 73岁),24例为男性,6例为女性,8例体能状态(PS)为0,22例PS为1,9例为ⅢA期,21例为ⅢB期。除1例患者外,所有患者均完成治疗。治疗期间常见的≥3级毒性包括中性粒细胞减少25例;感染5例;食管炎5例;放射性肺炎3例。总缓解率为83%。中位生存期为24个月(95%置信区间[CI],13 - 34个月),2年总生存率为50%(95%CI,32 - 68%)。中位无进展生存期为10个月(95%CI,8 - 20个月)。
顺铂和长春瑞滨诱导化疗后进行超分割加速放疗是可行且有前景的。未来需要开展剂量强化放疗联合化疗的研究。
