局限性晚期非小细胞肺癌手术治疗的共识和争论 总被引:2,自引:0,他引:2
局限性广泛期NSCLC手术预后较差,近年相关研究颇多,在发展过程中必然存在共识、也会有争论。共识:手术能否全部切除、T3胸壁侵犯者预后较中央型T3为好。T3伴否肺门淋巴结转移预后显然不同,纵隔淋巴结转移N2和预后密切相关,其中淋巴结转移数、部位、侵及淋巴结外膜和年生存率密切相关。术前诱导治疗可改善Ⅲ期长期年生存率,尚需扩大病例数及多中心随机研究,T4N3Ⅲb期NSCLC预后差,切除率低。争论:临床分期方法不同影响结果,如N2影像分期不如纵隔镜,但前者为无创伤性检查。术后放疗能降低复发,未见有益于生存。肺上沟瘤术前放疗并发症高。30%患者有胸内淋巴结跳站转移,手术时应切开纵隔仔细搜寻送检各站淋巴结。pN2作全肺切除死亡率高,不见得有益。隆突切除不适用于伴N1、N2患者。胸膜癌性积液原则上属非手术疾病。 相似文献

MVP和TVP治疗晚期非小细胞肺癌的前瞻随机研究 总被引:3,自引:1,他引:2
目的 评价MVP和TVP两种方案治疗晚期非小细胞肺癌的有效率、毒性和生存期。方法 66例晚期非小细胞肺痛随机分为两组,MVP组32例,TVP组34例,两组患者资料相似。MVP组:丝裂霉素(MMC)6~8mg/m^2,静注,第1天;长春花碱酰胺(VDS)2~3mg/m^2,静滴,第1、8天;顺铂(DDP)70~80mg/m^2,静滴,第1天或分两天。TVP组:吡喃阿霉素(THP)40~50mg/m^2,第1天,VDS和DDP同上。两方案均为一周期21天,每例完成2~4周期。结果 MVP组有效率为34%(完全缓解1例,部分缓解10例),TVP组有效率为56%(完全缓解1例,部分缓解18例),TVP有效率高于MVP组,但统计学无意义(X^2=2.269,P=0.132)。TVP组Ⅲ Ⅳ度骨髓抑制发生率高于MVP组,其中粒细胞抑制有显著性差异(79%与44%,X^2=7.458,P=0.006)。MVP组与TVP组的中位生存期分别为12个月与8个月,1年生存率53%与24%(X^2=4.943,P=0.026),2年生存率17%与6%,3年生存率6%与0。结论 MVP有效率相对较低,但血液毒性低,患者生存期和牛存率高,是晚期非小细胞肺癌化疗的合适方案。TVP方案近期有效率高,但血液毒性明显,与MVP方案比较,没有明显的生存受益。 相似文献

近年来有关非小细胞肺癌术后辅助化疗的治疗标准发生了显著变化,越来越多的前赡性、大样本随机临床试验和多项荟萃分析均证实辅助化疗,特别是新一代化疗药物的含铂联合方案能显著提高化疗反应和总体生存期,降低死亡危险比,且毒性反应均可耐受.因此,对于完整手术后的非小细胞肺癌,特别是Ⅰ B~Ⅱ期的患者采用辅助化疔是合理治疗方案. 相似文献

局部晚期非小细胞肺癌的化疗-放疗同步疗法(Con-current Chemoradiotherapy)是近年非小细胞肺癌治疗的重要进展之一.此疗法的策略思路是强化局部病灶控制的同时兼顾到全身转移微小病灶的治疗.临床前试验已证明:紫杉醇(Paclitaxl)和紫杉特尔(Docetaxel)等抗癌药具有放疗增敏作用,其机理很可能是把肿瘤细胞同步至细胞周期G2/M期,以利用放射治疗更有效地杀灭肿瘤细胞.在此,本人较系统地复习了第8届世界肺癌会议(都柏林,1997.8),第24届ASCO会议(洛杉矾,1998.5)和第5届中欧肺癌会议(布拉格,1998.9)有关此疗法的文献,作如下介绍.1 化疗与传统分割放疗相结合的化疗-放疗同步疗法1.1 美国学者Langer C等报道用泰素与卡铂组成的化疗方案与胸部传统分割放疗的同步疗法治疗局部晚期非小细胞肺癌.泰素(Taxol)175~225mg/m~2,3h,静脉滴注,第1天和第22天;卡铂(AUC=7.5),静脉滴注,第1天和第22天;G—CSF,5μg/kg/d,皮下注射.第2~15天和第23~26 相似文献

晚期非小细胞肺癌二线治疗的最新进展 总被引:2,自引:0,他引:2
肺癌患者的一线化疗总的缓解率不是很高,很多患者在化疗中或化疗后出现疾病进展。需进一步治疗。最近,对晚期NSCLC的二线化疗的临床研究显示,二线化疗不但可以提高患者的生存期,而且可以改善肿瘤相关症状和提高生活质量,且使患者对止痛药及姑息性放疗的需求减少。本文对最近晚期NSCLC的二线化疗的研究进行简要的总结。 相似文献

Advances in the understanding of the role of the immune system in tumor immunosurveillance have resulted in the recognition that tumors can evade immune destruction via the dysregulation of co-inhibitory or checkpoint signals. This has led to the development of a generation immunotherapeutic agents targeting the immune checkpoint pathway. Recent early phase studies of immune checkpoint modulators, such as CTLA-4, PD-1 and PD-L1 inhibitors in NSCLC have reported promising results with prolonged clinical responses and tolerable toxicity. This article provides an overview of co-stimulatory and inhibitory molecules that regulate the immune response to tumors, recent therapies that have been developed to exploit these interactions and the role of predictive biomarkers in treatment selection. 相似文献

Inhibition of the epidermal growth factor receptor is one of the most promising novel therapeutic strategies to be used in the treatment of patients with non-small cell lung cancer. A number of compounds that target the epidermal growth factor receptor are in an advanced stage of clinical development including both antibodies directed against the receptor and small molecule inhibitors of epidermal growth factor receptor tyrosine kinase activity. This drug profile focuses on the development of erlotinib, an orally available inhibitor of epidermal growth factor receptor tyrosine kinase. Results of clinical trials are reviewed, two trials of erlotinib in combination, one with paclitaxel and carboplatin, the other with gemcitabine and cisplatin, and the National Cancer Institute of Canada--Clinical Trials Group BR21, the first study to demonstrate a survival benefit for this class of compound in non-small cell lung cancer. The future role of erlotinib in the management of patients with non-small cell lung cancer is also discussed. 相似文献

While there have been advances in the treatment of lung cancer, they have been marginal in comparison with recent advances in the chemotherapy and molecularly targeted treatment of breast cancer, colorectal cancer and genitourinary cancer. Lung cancer is an extremely difficult disease to treat, and to obtain positive results and to develop new standard treatment. The results of clinical trial on gefitinib and erlotinib suggest that the evaluation of molecular target drugs seems to be quite difficult in unselected patient population and may be different from cytotoxic drugs. We need to find out specific molecular biomarkers for each drug. With global studies in view, it will be essential to obtain even more significant results by sophisticated clinical trials in selected patient populations and contribute to improving the treatment outcome of lung cancer patients. 相似文献

Antiangiogenic drugs in non-small cell lung cancer treatment 总被引:2,自引:0,他引:2

PURPOSE OF REVIEW: A promising therapeutic target is the vascular endothelial growth factor pathway - a key mediator of tumor angiogenesis - which is important in tumor growth, invasion, and metastasis. This review focuses on the available clinical data on drugs targeting the vascular endothelial growth factor - vascular endothelial growth factor receptor pathway in the treatment of non-small cell lung cancer. RECENT FINDINGS: The therapeutic value of inhibiting the vascular endothelial growth factor pathway has been demonstrated by using drugs that prevent vascular endothelial growth factor receptor binding and by using drugs that inhibit receptor activation. Two antiangiogenic drugs exemplify these mechanisms: bevacizumab (Avastin; Genentech, South San Francisco, California, USA), a humanized monoclonal antibody that acts by binding and neutralizing vascular endothelial growth factor; and ZD6474 (Zactima; AstraZeneca, Macclesfield, UK), a small-molecule inhibitor of vascular growth factor receptor and epidermal growth factor receptor tyrosine kinase activity. Recently, the first results of a large, phase III randomized clinical trial of bevacizumab in combination with platinum-based doublet chemotherapy have been reported in patients with nonsquamous non-small cell lung cancer. SUMMARY: The inhibition of tumor angiogenesis is a key therapeutic strategy that holds great promise for the advancement of metastatic lung cancer therapy. The combination of bevacizumab and conventional chemotherapy could offer a new therapeutic option in selected non-small cell lung cancer histotypes. 相似文献
