Abstract：

Objective To evaluate the effect of thoracic radiation therapy(TRT) on patients with extensive stage small-cell lung cancer(SCLC). Methods One hundred and fifty-four patients with extensive stage SCLC treated in our department between January 2003 and December 2006 were enrolled in this study.Eighty nine patients received chemotherapy and thoracic radiation therapy(ChT/TRT),and 65 patients were treated with chemotherapy alone(ChT without TRT).The chemotherapy was CE(carboplatin and etoposide),PE(cisplatin and etoposide) or CAO(CTX,ADM and VCR) regimens.The total dose of thoracic irradiation was 40-60 Gy with 1.8-2.0 Gy per fraction. Results For the whole group,the median survival time(MST) was 13.7 months,the 2-year and 5-year overall survival rates were 27.9% and 8.1%,respectively.The MST,overall survival rates at 2 years and 5 years in the ChT/TRT group and ChT without TRT group were 17.2 months,36.0%,10.1% and 9.3 months,16.9%,4.6%,respectively(P =0.001).The median progression-free survival(PFS) for all patients was 8.0 months,the 2-year and 5-year PFS were 13.6% and 8.2%,respectively.The median PFS,2-year and 5-year PFS in the ChT/TRT group and ChT without TRT group were 10.0 months,17.4%,10.5% and 6.2 months,9.8%,4.9%,respectively(P ＜0.001).The incidence of intra-thoracic local failure was 29.6% in the ChT/TRT group and 70.0% in the ChT/without TRT group(P = 0.000). Conclusions Chemotherapy plus thoracic radiation therapy can improve the overall survival,progress free survival and reduce local regional failure rate in patients with extensive stage SCLC compared with that by chemotherapy alone.     

广泛期小细胞肺癌胸部放疗研究进展

广泛期小细胞肺癌(ES-SCLC)预后差,生存期短。尽管铂类和依托泊苷组成的全身治疗方案以及预防性颅脑照射已经成为ES-SCLC的治疗方案,但仍面临着局部控制率和总体生存率低的挑战。放疗作为局部治疗手段,适用范围广,不仅可用于局部病变的根治性治疗,对晚期患者也可选择性地实施姑息治疗。胸部放疗可以改善ES-SCLC的局部...     

老年广泛期小细胞肺癌放疗价值研究

目的 探讨胸部放疗(TRT)对老年广泛期小细胞肺癌(ES-SCLC)患者预后的影响。方法 回顾分析天津医科大学肿瘤医院2010-2016年收治的83例≥65岁转移性ES-SCLC患者,所有入组患者均接受依托泊苷联合顺铂或卡铂标准方案化疗。经PSM倾向评分匹配有无TRT各入组35例。男56例、女14例,年龄65~85岁(中位数69岁),化疗1~11个周期(中位数4个周期),胸部照射剂量30~60 Gy (中位数50 Gy)。观察终点为总生存(OS)、无进展生存(PFS)、局部无复发生存(LRFS)。采用Kaplan-Meier方法计算生存率,Logrank比较组间差异,Cox回归模型多因素预后分析。结果 全组患者1年OS、PFS、LRFS率分别为40%、16%、21%;有无TRT患者的1年OS率分别为52%和29%(P=0.005),1年PFS率分别为30%和3%(P<0.001),1年LRFS率分别为38%和6%(P<0.001)。接受TRT并未增加患者不良反应的发生率(P=0.690)。结论 老年ES-SCLC患者加用TRT能够明显提高胸部肿瘤控制率,延长患者生存期,值得进一步进行大样本前瞻性研究证实。

Abstract：

Objective To investigate independent prognostic factors for overall survival (OS) in extensive disease small cell lung cancer (EDSCLC). Methods Between January 2003 and December 2006, 154 patients diagnosed with extensive stage small cell lung cancer were enrolled in this study.Prognostic factors such as gender, age, performance status, smoking history, weight loss, distant metastasis, the number of matastasis, brain metastasis, the cycle of chemotherapy and thoracic radiation therapy (TRT) for EDSCLC patients were evaluated by univariate and multivariate analysis. Results The median following-up time was 40. 5 months. The rate of follow-up was 92. 2%. The MST and overall survival rates at 3-year in smoking group and no-smoking group were 13 months, 11.8% and 17 months,22. 8%,respectively (χ2=3.40,P =0. 064);in ChT/TRT group and ChT group, they were 17. 2 months, 17.9%and 9.3 months,13.9%, respectively(χ2=10.47,P=0.001);and in the cycle of chemotherapy ≥4 group and ＜ 4 group, they were 16 months, 20. 1% and 9.3 months, 2. 9%, respectively (χ2=17.79,P=0. 000). By multivariate analysis, smoking history was a statistically significant unfavorable factor for OS in EDSCLC patients (versus no-smoking, hazard ratio (HR)=1.462, χ2=4.40, P=0.036). In addition, ≥4 cycles of chemotherapy and TRT were favorable prognostic factors ( ≥4 cycles vs ＜4 cycles, HR =0. 420,χ2 = 17. 17, P = 0. 000; ChT/TRT vs ChT, HR = 0. 634, χ2 = 6. 20, P = 0. 013). Conclusions Smoking is a independent unfavorable prognostic factor and ≥ 4 cycles of chemotherapy And TRT are independent favorable prognostic factors for OS in EDSCLC.

放疗联合长春瑞滨加顺铂同步或序贯化疗治疗Ⅲ期非小细胞肺癌的临床研究

为了比较放射治疗联合长春瑞滨（NVB）加顺铂（DDP）同步与序贯放化疗治疗Ⅲ期非小细胞肺癌（non-small cell lung cancer,NSCLC）的疗效及毒副反应,将55例Ⅲ期NSCLC患者随机分成2组,同步放化疗组（26例）：放疗第1天起即同时开始化疗。序贯放化疗组（29例）：入组后先予化疗2个疗程,再单独予放疗。结果：近期有效率（CR＋PR）同步放化疗组为76.9%（20/26）,序贯放化疗组为51.7%（15/29）,P=0.0456。1、2年生存率同步放化疗组为69.2%（18/26）、42.3%（11/26）,序贯放化疗组为51.7%（15/29）、17.2%（5/29）。2年生存率差异有统计学意义,P=0.041。同步放化疗组白细胞下降与放射性食管炎较序贯放化疗组严重,P〈0.05;但经治疗后,患者大多能耐受。初步研究结果提示,放射治疗联合NVB加DDP同步放化疗治疗Ⅲ期NSCLC的疗效优于序贯放化疗,不良反应增大但可耐受,值得进一步研究。     

广泛期小细胞肺癌化疗后脑预防照射及颅外病变放疗的Ⅱ期临床研究

Objective To investigate the efficacy and safety of thoracic radiotherapy (TR) and prophylactic cranial irradiation (PCI) in patients with extensive small cell lung cancer (SCLC) who show response to chemotherapy. Methods From July 2010 to March 2012, 30 patients with a pathological or cytological diagnosis of extensive SCLC who showed response to 4-6 cycles of chemotherapy with carboplatin plus etoposide or chemotherapy with cisplatin plus etoposide were included in the study. The median age of patients was 57 years (range, 40-71 years). All the patients received TR (50-60 Gy) and PCI (25 Gy). The short-term efficacy was assessed by RECIST 1.1, and the toxicities were evaluated according to CTCAE 3.0 and RTOG radiation morbidity scoring criteria. Results Twenty-nine of the 30 patients completed the TR and PCI. Of these patients, 13% showed complete remission, 27% showed partial remission, and 60% showed stable disease, and the disease control rate was 100%. Progression was seen in 16 patients after effective treatment, including 1 patients with locoregional failure (LRF) alone and 15 patients with distant failure (DF)(9 patients with DF alone and 6 patients with locoregional and distant metastases, 4 patients with brain metastasis). The follow-up rate was 100%. The 1-year LRF rate and DF rate were 24% and 51%, respectively. The 1-year overall survival rate and disease-free survival rate were 71% and 37%, respectively. The acute toxicities included grade ≥2 hematological toxicity and grade ≥2 radiation esophagitis, which occurred in 33% and 13% of all patients. Conclusions TR and PCI have good short-term efficacy and safety in extensive SCLC patients with response to chemotherapy and can reduceDOI:10.3760/cma.j.issn.1004-4221.2013.05.007基金项目:北京希望马拉松专项基金(N2010-8)作者单位:100021 北京协和医学院中国医学科学院肿瘤医院肿瘤研究所放疗科(张文珏、周宗玫、陈东福、梁军、冯勤付、张红星、王小震、惠周光、肖泽芬、吕纪马、王绿化),内科(李峻岭)通信作者:周宗玫,Email:zhouzongmei2013@163.combrain metastases and local recurrence.

广泛期SCLC不同放疗分割方式疗效比较

目的 评价不同放疗分割方式与广泛期SCLC患者LC与OS相关性,以明确不同分割方式与预后关系。方法 2010—2015年间初治的110例广泛期SCLC患者接受放化疗,根据放疗剂量分为大分割组31例(30~45 Gy分10~15次)与常规分割组79例(54~60 Gy分27~30次)。90.9%患者临床分期为Ⅳ期。21例患者伴有脑转移。39例行PCI。Kaplan-Meier法计算生存率并Logrank法检验,组间分类数据行χ²检验。结果 全组2年样本量为85例,全组OS、PFS、LC率分别为27.7%、17.5%、38.9%。大分割组与常规分割组的2年OS分别为35%与26%(P=0.886), 2年PFS分别为18%与16%(P=0.560), 2年LC率分别为67%和36%(P=0.159)。PCI与否的2年OS分别为44%和18%(P=0.044)。全组共84例患者治疗失败,其中局部复发11例、远处转移41例、局部复发+远处转移32例。结论 大分割放疗与常规分割放疗疗效相似,但照射时间明显缩短,大分割放疗需要进一步研究。     

术后放疗在接受新辅助化疗联合手术切除的非小细胞肺癌的应用进展

新辅助化疗联合手术切除是非小细胞肺癌的标准治疗模式之一,但其疗后局部区域复发率较高。术后放疗(PORT)能显著降低该模式治疗后的局部区域复发率,但对改善生存的价值尚未完全明确:一部分研究认为其不能改善Ⅱ-ⅢA(N2)期患者的生存,另一部分研究则认为其可使高危患者的生存获益。目前此类患者PORT的指征包括R1、R2切除及ypN2期。PORT技术首选三维适形与调强放疗;R0切除患者放疗剂量50~54 Gy可兼顾疗效与安全;靶区范围目前尚无定论,但研究多倾向于只进行受累淋巴结区域照射。大部分研究中PORT的不良反应在可接受范围之内。但目前相关研究的证据等级较低,尚需前瞻性研究来证实上述结论。     

非小细胞肺癌术后放射治疗开始时间与预后

目的 分析非小细胞肺癌术后放射治疗的预后因素,主要讨论术后放射治疗开始时间对预后的影响。方法 对本院收治的１３２例非小细胞肺癌术后放射治疗病例进行回顾性分析,其中Ⅰａ期７例,Ⅰｂ期２例,Ⅱａ期８例,Ⅱｂ期５４例,Ⅲａ期４６例,Ⅲｂ期１５例,手术和术后放射治疗开始的间隔时间为１２～９０ｄ。放射治疗采用＾６０Ｃｏ或１０ＭＶＸ射线,剂量为４０～７２Ｇｙ。结果 单因素及多因素分析显示,临床分期、卡氏评分、手术与术后放射治疗开始的间隔时间长短为影响预后的重要因素。术后放射治疗开始的间隔时间长者（３７～９０ｄ）５年生存率明显比间隔时间短者（１２～３６ｄ）高（Ｘ＾２＝９．２７,Ｐ＝０．００２）。进一步分析显示,Ｎ０－１期病例术后放射治疗开始间隔时间长者的５年生存率明显比放射治疗开始间隔时间短者高（Ｘ＾２＝５．６４,Ｐ＝０．０     

广泛期SCLC化疗后IMRT的疗效分析

目的 回顾研究广泛期SCLC化疗后IMRT的疗效及预后。方法 回顾分析2007—2012年在本院放疗科接受化疗+IMRT的130例初治广泛期SCLC患者,化疗方案以EP、CE方案为主,放疗剂量32 Gy~63 Gy,35例患者进行了PCI。Kaplan-Meier法计算生存率,Logrank法单因素预后分析,Cox模型多因素预后分析。结果 随访率96.1%。全组治疗毒性轻微,≥2级血液学毒性及放射性食管炎发生率分别为22.3%、12.2%,≥2级RP发生率7.7%。放疗后达CR、PR、SD、PD者分别占4.6%、72.3%、6.2%、13.1%,疗效未能评价5例,客观有效率76.9%。中位生存期18个月(4~66个月),1、2年OS率分别为72.3% 、38.3%。30例(23.1%)患者放疗后发生局部区域失败,83例(63.8%)发生远处失败。26例放疗计划可恢复的局部区域失败患者中,22例单纯照射野内失败,2例单纯野外失败,2例野内野外同时失败。单因素分析中年龄、LDH水平、放疗剂量、PCI是影响预后因素(P=0.014、0.049、0.043、0.003),多因素分析中放疗剂量、PCI是影响预后因素(P=0.021、0.007)。初诊无脑转移患者PCI明显改善生存(HR=2.318,95%CI为1.388~3.871;P=0.003)并降低累积脑转移率(18.4%:37.2%,P=0.038)。胸部放疗EQD₂剂量达54 Gy可改善OS (HR=1.615,95%CI为1.016~2.567;P=0.043),并有改善PFS趋势(HR=1.49,95%CI为0.965~2.299,P=0.072)。结论 化疗有效的广泛期SCLC行胸部放疗可提高LC率及OS率,适当提高胸部剂量可改善患者预后。PCI可显著改善OS并降低脑转移发生率。
