摘要
目的探讨老年Ⅳ期非小细胞肺癌(NSCLC)三维放疗的重要性。方法2003—2010年间201例NSCLC化疗同期三维放疗疗效患者入组,其中老年(≥65岁)和〈65岁患者分别为67例和134例。Kaplan—Meier法生存分析,Cox模型多因素预后分析。结果随访率为97.8%。≥65岁和〈65岁患者完成4~5周期化疗分别占30%和55%,放疗剂量≥63Gy分别占42%和49%。365岁和〈65岁4~5周期化疗同期≥63Gy放疗的中位生存期(MST)分别为17个月和14个月(x2=0.76,P=0.384)。全组患者放疗363Gy和〈63Gy的MST、1、2、3年生存率分别为17个月和8个月、65%和23%、30%和13%、24%和9%(x2=7.90,P=0.005),任何化疗强度均示363Gy较〈63Gy的MST显著延长(x2=9.54,P=0.023)。365岁、放疗363Gy者同期d~5周期和2~3周期化疗的MST分别为14个月和8个月(X2=1.82,P=0.178)、17个月和17个月(x。=0.47,P=0.492)。多因素预后分析显示近期疗效(p=0.600,P=0.003)、肿瘤转移数(p=0.670,P=0.040)对生存有影响。结论化疗同期三维放疗延长部分老年Ⅳ期NSCLC生存期,三维放疗的重要性对老年患者个体化治疗更明显。
Objective To evaluate the importance of three-dimensional radiotherapy for elderly patients of stage Ⅳ non-small cell lung cancer (NSCLC). Methods Comparing with treatment outcome of ≥65 years 67 patients and 〈 65 years 134 patients using concurrent chemotherapy and thoracic three-dimensional radiotherapy during 2003 to 2010 years. Survival analysis was taken by Kaplan-Meier method. The multivariate prognosis was analyzed by Cox model. Results The follow-up was 97.8%. The percentage of 〉165 years and 〈 65 years patients accepted with concurrent 4 - 5 cycles chemotherapy were 30% and 55%, and with 42% and 49% patients with radiotherapy≥63 Gy. The median survival time (MST) were 17 months and 14 months ( X2 = 0. 76, P = 0. 384) for ≥65 years and 〈 65 years patients accepted with concurrent 4 -5 cycles chemotherapy concurrent t〉63 Gy radiotherapy respectively. The MST and 1-, 2-,5- year overall survival rate were 17 months and 8 months,65% and 23% , 30% and 13% , 24% and 9% (X2 = 7.90 ,P = 0. 005 ) for whole groups patients treated with chemotherapy concurrent ≥ 63 Gy and 〈 63 Gy radiotherapy. And the MST of patients t〉 63 Gy was significantly longer than those with 〈 63 Gy either concurrent chemotherapy any cycles ( X2 = 9.54 ,P = 0. 023 ). The MST were 14 months and 8 months (X2 = 1.82,P=0.178),17 months and 17 months (X2=0.47,P=0.492) for ≥ 65 years and ≥ 63 Gy radiotherapy patients accepted with concurrent 4 - 5 cycles and 2 - 3 cycles chemotherapy concurrent respectively. Multivariate analysis showed local response ( 13 = 0. 600, P = 0. 003 ) and numbers of tumor metastasis ( [3 = 0. 670, P = 0. 040 ) were independent factors for survival. Conclusions For a part of elderly patients of stage Ⅳ NSCLC, concurrent chemotherapy and thoracic three-dimensional radiotherapy can prolong survival time with acceptable toxicity. Perhaps radiotherapy is more important.
