Abstract

BACKGROUND AND
OBJECTIVE: Small cell lung cancer (SCLC) is the most malignant neuroendocrine tumor but highly sensitive to chemotherapy and radiotherapy. At present, the standard first-line chemotherapy regimen of extensive-stage SCLC is platinum combined etoposide regimen. However, most patients who receive first-line chemotherapy will relapse within one to two years. Once recurrent, it indicates poor prognosis. In this study, we analyzed the survival among all extensive-stage SCLC and patients who received first-line chemotherapy and determined prognostic factors.
METHODS: Total of 394 patients who were diagnosed as extensive-stage small cell lung cancer from February 2001 to December 2011 hospitalized in Peking Union Medical College Hospital were collected. Kaplan-Meier method was used to calculate the overall survival (OS) and progression-free survival (PFS). Univariate analysis and Cox regression analysis were used to detect the influence factors of survival.
RESULTS: The median OS of all extensive-stage small cell lung cancer was 14.8 months; 1-year, 2-year and 5-year survival rates were 58.9%, 27.2% and 7.8%, respectively. According to the results of univariate and Cox multivariate analysis, OS of extensive-stage SCLC was closely associated with age (P=0.006), ECOG PS (P=0.021), liver metastasis (P<0.001), bone metastasis (P<0.001) and chemotherapy (P<0.001). The mortality risk of patients who didn't receive chemotherapy was 4.919 times higher than that who received; the mortality risk of patients without liver, bone metastasis was reduced by approximately 50 percent. The first-line chemotherapy was mainly EP (DDP+VP-16) or CE (CBP+VP-16) regimens (accounting for 82.8%) with 4-6 cycles. The median OS and PFS in first-line chemotherapy were 15.1 months and 7.5 months, respectively. The result of Cox regression analysis indicated that OS in first-line chemotherapy was remarkably related to smoking history (P=0.041), liver metastasis (P<0.001), bone metastasis (P<0.001), chemotherapy cycle number (P<0.001); PFS was relevant with smoking history (P=0.003), liver metastasis (P=0.001), bone metastasis (P<0.001), chemotherapy cycle number (P<0.001). Thoracic radiotherapy was not an independent influence factor of OS and PFS in extensive-stage small cell lung cancer.
CONCLUSIONS: The patients who were younger than 60-year old, with good KPS, absence of liver and bone metastasis had better prognosis. Patients should receive chemotherapy with first-line standard regimen (CE/EP regimen). It was beneficial to survival if the effect of first-line chemotherapy was SD or PR-CR and the proper chemotherapy cycle number was 4-6 cycles. The role of thoracic radiotherapy in extensive-stage small cell lung cancer needed to be investigated further.

小细胞肺癌(small cell lung cancer, SCLC)是恶性程度极高的神经内分泌肿瘤,属于肺癌的未分化型,约占所有肺癌的15%[。初诊时约60%-70%的SCLC患者属于广泛期,30%-40%属于局限期。广泛期SCLC中位生存时间约10个月-14个月,5年生存率为6.5%[。近30年虽然有新的化疗药物出现,但广泛期SCLC患者生存情况的改善不明显。1981至2008年所有广泛期SCLC的Ⅲ期临床数据显示,生存时间每年只提高了0.63天[。本文回顾性地分析了在北京协和医院住院治疗并于2001年2月-2011年12月经病理学或细胞学确诊的394例广泛期SCLC患者的临床资料,研究广泛期SCLC的总体和一线化疗的生存情况及其影响因素,旨在为临床治疗广泛期SCLC和判断预后提供一定的参考依据。

资料与方法

研究对象

收集于2001年1月-2011年12月在北京协和医院住院治疗的SCLC患者的临床资料。所有患者需符合以下条件:①年龄 > 18周岁;②经细胞学或组织病理学检查确诊为SCLC;③经胸腹部增强CT、全身骨扫描、头颅增强MRI检查,根据美国退伍军人肺癌研究组(Veterans Administration Lung Study Group, VALG)制定的分期方法判定为广泛期SCLC;④病历资料完整。

研究方法

收集患者完整的临床资料,包括:患者的年龄、性别、吸烟情况和ECOG(Eastern Cooperative Oncology Group)评分;病理获取时间、分期、转移部位;化疗方案、最佳疗效、疾病进展时间、是否行胸部放疗;末次随访时间及死亡时间。采用电话形式进行随访,随访时间至患者死亡时间或2013年4月15日为止,存活时间以月为单位。

评定标准

根据实体瘤疗效评价标准(Response Evaluation Criteria in Solid Tumor, RECIST)评估疗效,分为完全缓解(complete response, CR)、部分缓解(partial response, PR)、稳定(stable disease, SD)和进展(progressive disease, PD)。有效率(RR)=(CR+PR)/全部病例数×100%。敏感复发是指初始治疗有效且初始治疗结束到疾病进展的时间 > 90天;耐药复发是指初始治疗结束到疾病进展的时间≤90天。总生存时间(overall survival, OS)指从病理获取时间至患者死亡或末次随访时间(月)。无进展生存时间(progression-free survival, PFS)指从病理获取时间至疾病进展或患者死亡的时间或末次随访时间(月)。

统计学处理

采用SPSS 18.0软件进行数据统计分析。采用Kaplan-Meier法计算患者的OS和PFS,并绘制生存曲线。采用单因素以及Cox回归多因素分析各种因素对生存期的影响。P < 0.05为差异有统计学意义。

结果

全组一般情况

查阅于2001年1月-2011年12月在北京协和医院住院治疗的SCLC患者的临床资料802例,根据实验对象入选标准,符合条件的广泛期SCLC患者共394例。全组患者年龄20岁-93岁,中位年龄为62岁。病理组织学上,经典SCLC 389例,混合癌5例。最常见的转移部位包括骨、胸腔积液、肝、脑和肾上腺。患者一般情况见表 1。

全组治疗情况

394例患者中25例未行化疗,369例接受化疗;164例患者进行了胸部放疗,91例患者在出现脑转移后进行了脑部放疗,8例行预防性全脑放射治疗。369例进行化疗患者的化疗方案包括EP或CE[顺铂(DDP)或卡铂(CBP)+依托泊苷(VP-16)]方案各75例和230例,其他化疗方案64例包括拓扑替康(TPT)+DDP方案12例、CODE[环磷酰胺(CTX)+阿霉素(ADM)/表阿霉素(EPI)+DDP+VP-16]方案10例、氨柔比星+DDP方案10例、紫杉醇(TAX)+DDP/CBP方案8例、替尼泊苷(VM26)+卡莫司汀(BCNU)方案4例、力比泰+DDP方案4例、口服VP-16方案4例、异环磷酰胺(IFO)+VP-16方案3例、吉西他滨(GEM)+DDP方案2例、伊立替康(CPT-11)+DDP方案2例、IFO+CBP方案1例、丝裂霉素(MMC)+DDP方案1例、VIP(VP-16+IFO+DDP/CBP)方案1例、CPE(CBP+TAX+VP-16)方案1例、COME[CTX+长春新碱(VCR)+甲氨蝶呤(MTX)+VP-16]方案1例。化疗1个-3个疗程者102例,4个-6个疗程者221例,7个疗程以上者46例;疗效PD者28例,SD者79例,PR/CR者197例,疗效不详者65例;化疗后耐药复发者158例,3个月-6个月复发者52例,6个月以上复发者31例,复发情况不详者128例;接受化疗的患者中126例接受了放射治疗。

全组生存情况及其影响因素

全组的中位总生存时间为14.8个月。1年、2年、5年生存率分别为58.9%、27.2%、7.8%。分析性别、年龄、吸烟情况、ECOG评分、转移部位、是否进行化疗、是否进行胸部放疗对全组394例广泛期SCLC OS的影响。单因素分析的结果表明广泛期SCLCOS与年龄、ECOG评分、肝转移、骨转移、是否化疗、是否胸部放疗密切相关,其中未进行化疗患者的死亡风险是进行化疗的患者的4.919倍,若无肝、骨转移则死亡风险下降约50%;与其他因素如性别、是否吸烟、脑转移、肾上腺转移、有无胸腔积液的关系无统计学意义(表 1)。多因素分析的结果表明年龄、ECOG评分、肝转移、骨转移和是否化疗是广泛期SCLC OS的独立影响因素(表 2)。单因素分析结果显示广泛期小细胞肺癌OS与是否进行胸部放疗有关,但多因素分析结果显示OS与是否进行胸部放疗无关。

一线化疗生存情况及其影响因素

接受一线化疗广泛期SCLC患者的中位OS为15.1个月。分析年龄、性别、ECOG评分、吸烟情况、不同转移部位、化疗方案、化疗疗效、化疗疗程数、是否进行胸部放疗、复发时间对一线化疗OS的影响。单因素分析的结果显示一线化疗广泛期小细胞肺癌的OS与年龄、ECOG评分、肝转移、骨转移、化疗疗效、化疗疗程数、胸部放疗、复发时间相关(表 3)。多因素分析的结果显示一线化疗广泛期SCLCOS只与吸烟、骨转移、肝转移、化疗疗程数相关(表 4)。一线化疗的中位PFS为7.5个月。同样分析各因素对一线化疗PFS的影响。单因素和多因素分析的结果均显示一线化疗PFS与吸烟、肝转移、骨转移、化疗疗程数相关,单因素分析的结果显示一线化疗PFS与胸部放疗相关,但多因素分析的结果显示PFS与胸部放疗无关(表 3,表 5)。

讨论

本研究全组中位OS为14.8个月,1年、2年、5年生存率分别为58.9%、27.2%、7.8%,一线化疗中位OS为15.1个月,中位PFS为7.5个月,与文献报道基本一致[,另外,3个时间段OS的比较提示广泛期SCLC的生存情况未得到明显改善。全组OS与年龄、ECOG评分、肝转移、骨转移、是否化疗密切相关。一般SCLC多于中老年发病,该研究394例患者的年龄跨度为20岁-93岁,中位年龄为62岁。年龄 < 60岁死亡风险较年长者下降32%,这可能与年龄较轻的患者一般状况较好、合并的全身性疾病少,更能耐受化疗有关。多项研究显示ECOG评分明显与SCLC的预后相关[,该研究同样证实了该观点。广泛期SCLC的治疗核心是化疗,未接受化疗的广泛期SCLC的生存期只有1个月-3个月,化疗比最佳支持治疗(best supportive care, BSC)能延长生存期[。本研究中进行化疗的患者的中位总生存时间为15.1个月,未进行化疗的中位总生存时间为1.6个月,未进行化疗患者的死亡风险是进行化疗的患者的4.919倍,故广泛期SCLC患者应积极接受化疗。另一个影响预后的因素是转移部位,有研究称肝转移与预后明显相关[,而且转移部位越多预后越差[,本研究证实若无肝、骨转移则死亡风险下降约50%。 SCLC患者接受一线化疗,则OS、PFS都与化疗疗效、化疗疗程数相关,与化疗方案无关。首先,化疗疗效是预测广泛期SCLC预后的重要指标。本研究达到PR/CR患者的中位OS和PFS分别为16.6个月和8.2个月,PD的中位OS和PFS分别为5.9个月和2.0个月,即PR/CR患者较PD患者的OS延长1年、PFS延长半年,死亡风险下降62%,疾病进展风险下降85%,故如果化疗疗效能达到PR将有益于生存。这与临床经验相一致,因为如果疗效达到PR说明患者对化疗敏感,而如果是PD则提示耐药。而达到SD的患者的OS为13.4个月,与PR/CR患者的OS比较无统计学意义(χ2=5.512, P=0.019 > α’=0.05/6=0.008),即达到SD患者的生存时间并没有明显差于PR/CR的患者。其次,化疗疗程数同样可以影响OS和PFS。单因素结果显示化疗1个-3个疗程者的OS和PFS只有7.7个月和3.2个月,因为一般化疗1个-3个疗程者一般状况较差或者对化疗药物不敏感;化疗4-6疗程和≥7疗程的中位OS差别不大(χ2=2.706, P=0.100),而两者的中位PFS有明显差异(χ2=14.580, P < 0.001);Bozcuk[的meta分析也提示增加化疗周期(即维持治疗)只能增加中位进展时间,却没能明显改善生存,故适合的化疗疗程数是4个-6个疗程。值得注意的是胸部放疗在全组OS、一线化疗的OS和PFS的单因素和多因素分析结果是不一致的,有关胸部放疗在广泛期SCLC治疗中的作用有待进一步研究。 综上所述,年龄 < 60岁、体能状况好、无肝、骨转移的广泛期SCLC患者预后更好。广泛期SCLC患者应积极进行化疗,一线化疗的化疗疗效达到SD、PR-CR有益于生存;适合的化疗疗程数目是4个-6个疗程。
