摘要
目的:评价三维适形调强放疗联合化疗在治疗中、晚期非小细胞肺癌(NSCLC)的作用.方法:72例中、晚期NSCLC患者采用分组治疗.A组采用常规放疗加化疗,共30例;B组采用三维适形放疗加化疗,共30例;C组采用三维适形调强放疗加化疗,共12例.三组均采用铂类联合盖诺方案化疗1个周期后放疗,放疗结束后再化疗3~5个周期.结果:A组有效率(CR+PR)43.3%,B组有效率70%.0,C组有效率83.3%,A组与B组,A组与C组差异有统计学意义,P<0.05;1年生存率:A组40.0%(8/20),B组为66.7%(12/18),C组为100.0%(4/4).B、C组合并后的1年生存率与A组差异有统计学意义,P=0.03;三组的骨髓抑制等基本相同;放射性食管炎,三组间差异无统计学意义,P=0.16.急性放射性肺炎:A组56.7%,B组33.3%;C组16.7%.A组与C组差异有统计学意义,P=0.031.结论:在中、晚期NSCLC的治疗中,三维适形或调强放疗联合化疗与与常规放疗联合化疗相比,具有疗效好、毒副反应轻、患者容易耐受等特点;适形调强放疗在不增加放疗不良反应的同时,能够提高1年生存率和靶区的照射剂量.
OBJECTIVE:To evaluate the effect of intensity modulated radiation therapy (IMRT) for medium and late stage non small cell lung cancer. METHODS: Seventy-two patients with medium and late stage non-small-cell lung cancer were grouped. Group A consisted of 30 patients, receiving conventional radiotherapy plus chemotherapy. Group B consisted of 30 patients, treated with three-dimensional conformal radiotherapy (3-DCRT) plus chemotherapy. Twelve patients were involved in Group C, and IMRT in conjunction with chemotherapy was performed in this group. All these patients received one cycle chemotherapy of Navetbine+Cisplatin (NP) before radiotherapy and other three to five cycles after radiotherapy. RESULTS: The overall response rate (CR+PR) was 43. 3% in Group A, and 70. 0%, 83. 3% in Group B and C respectively. In Group A there was a significant difference (P〈0. 05) compared with Group B. The same result could be seen between Group A and C. In terms of one-year survival rate, it was 40% in Group A, and 66. 7%, 100.0% in Group B and C respectively. The one-year survival rate in combination with Group B and C was statistically different from that in Group A, P= 0. 03. Myelosuppression in the three groups was similar. Esophageal toxicity was also observed. There was no statistical difference among the three Groups, P= 0. 16. Acute radiation-induced pulmonitis was 56. 7% in Group A, 33. 3% in Group B and 15. 7% in Group C. Significant difference was found between Group A and Group C, P=0. 031. CONCLUSIONS: 3-DCRT or IMRT combined with chemotherapy in the treatment of non-small cell lung cancer has the feature of good efficacy, less side effects and well-tolerated approach, in contrast with the conventional radiotherapy plus chemotherapy. IMRT can increase not only the one-year survival rate but radiation dose for target, without enhancing the side effect of radiotherapy.
