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

Ⅰb~Ⅲa期非小细胞肺癌术后辅助化疗的进展 总被引:1,自引:0,他引:1
肺癌是危害人民生命健康的常见恶性肿瘤,其发病率及死亡率居我国大中城市肿瘤之首位,也是世界人类的最主要死亡原因。由于肺癌患者发病 年龄较大,常合并多器官系统疾病,且肺叶或全肺切 除术后对化疗耐受性差,再加之早期关于术后辅助 化疗临床研究成功的报道不多,因而对非小细胞肺 癌(NSCLC)的术后辅助化疗一直存在争议。本文 通过对近年来国际间几项重要的术后辅助化疗研究 的剖析并结合2004年美国临床肿瘤年会(ASCO)公 布的最新研究进展,以期为我国肺癌临床实践给予正确的引导。 相似文献

非小细胞肺癌手术后有1/3~1/2病人复发、转移,手术后辅助化疗是令人关注的问题.自20世纪60年代起人们就在这一领域进行尝试,但一直未获得期望的结果.1995年英国医学杂志发表了第一篇有关问题的Meta分析结果,术后用含顺铂的联合化疗方案有延长远期生存的趋势.近年来陆续发表的前瞻性随机临床研究显示对术后早期非小细胞肺癌,特别是IB期病人使用含铂类药物方案化疗可以延长远期生存,但根据统计学要求,目前所积累的临床资料样本量尚不能做出最后结论. 相似文献

Nearly half of all patients who undergo surgical resection of localized non-small cell lung cancer (NSCLC) will develop and ultimately die of recurrent disease. The postoperative radiotherapy (PORT) meta-analysis showed adjuvant thoracic radiotherapy to have a detrimental effect on survival in this patient population. A meta-analysis of early trials of adjuvant chemotherapy by the Non-Small Cell Lung Cancer Collaborative Group showed that while chemotherapy with alkylating agents was also detrimental, chemotherapy with cisplatin-based adjuvant chemotherapy was associated with an improved hazard ratio for death (HR = 0.87), equating to a 5 percent survival benefit at 5 years. However, the result was not statistically significant (p = 0.08). Recently, results have been reported for several large Phase III trials of adjuvant chemotherapy which differed with respect to the stage of resected disease included, the type of chemotherapy used and the use of post-operative radiotherapy. Three trials (IALT, JBR 10, and ANITA) that utilized cisplatin-based doublets showed a significantly positive survival benefit of adjuvant chemotherapy in patients with Stage II-IIIA NSCLC. The magnitude of this benefit, which was suggested to be 4-5 percent at 5 years in the meta-analysis and by the IALT study, may be as large as 8-15 percent as indicated by more recent studies with modern platinum-based doublet chemotherapy. These data indicate that medically fit patients with resected Stage II-IIIA NSCLC should be offered adjuvant chemotherapy with a modern cisplatin-based doublet. 相似文献

A review of the published clinical trials of surgical adjuvant chemotherapy in lung cancer indicated that in the majority of nonrandomized trials, conclusions favored the use of adjuvant chemotherapy. On the other hand, most randomized trials were unable to show any statistically significant difference in survival or disease-free interval between treated groups and controls. On the contrary, in several studies the survival was better in the control group. It was concluded that adjuvant chemotherapy has no place in the routine treatment of resectable lung cancer; however, further prospective controlled randomized trials are needed using new agents, new combinations, or new schedules. 相似文献

The past decade has witnessed renewed interest in studies exploring the benefits of adjuvant (postoperative) chemotherapy (± radiation therapy) in patients with resected non-small cell lung cancer (NSCLC). Recently completed adjuvant trials have included a heterogeneous group of patients with resected stages I to IIIA NSCLC. With rare exception, the published results of these studies indicate adjuvant chemotherapy imparts a significant overall survival advantage. Subset analyses suggest survival benefit occurs primarily in patients with resected stage II or IIIA and is less likely to occur in stage I patients. This apparent lack of survival benefit in stage I patients was seemingly validated in a prospective trial conducted by the Cancer and Leukemia Group B in which stage IB patients were randomized to observation or adjuvant carboplatin and paclitaxel. Survival at 5 -years was identical in the two arms of this trial. By contrast, two contemporary postoperative chemotherapy trials also conducted exclusively in stage I NSCLC patients yielded positive survival results. The divergent outcome of the prospective trials along with the negative subset analyses has created uncertainty as to the utility of postoperative adjuvant chemotherapy in stage I NSCLC. Herein we review the data underlying this controversy and offer a proposed algorithm to aid the clinician in selecting patients whom we believe may benefit from adjuvant chemotherapy. The treatment algorithm is based on currently available tumor- and host-related factors that affect prognosis. 相似文献

Non-small cell lung cancer (NSCLC) is the biggest cancer killer in the United States and worldwide. In 2011, there are estimated to be 221,130 new cases of lung cancer in the United States. Over a million people will die of lung cancer worldwide this year alone. When possible, surgery to remove the tumor is the best treatment strategy for patients with NSCLC. However, even with adjuvant (postoperative) chemotherapy and radiation, more than 40% of patients will develop recurrences locally or systemically and ultimately succumb to their disease. Thus, there is an urgent need for developing superior approaches to treat patients who undergo surgery for NSCLC to eliminate residual disease that is likely responsible for these recurrences. Our group and others have been interested in using immunotherapy to augment the efficacy of current treatment strategies. Immunotherapy is very effective against minimal disease burden and small deposits of tumor cells that are accessible by the circulating immune cells. Therefore, this strategy may be ideally suited as an adjunct to surgery to seek and destroy microscopic tumor deposits that remain after surgery. This review describes the mechanistic underpinnings of immunotherapy and how it is currently being used to target residual disease and prevent postoperative recurrences after pulmonary resection in NSCLC. 相似文献

To evaluate the efficacy and safety of gemictabine combined with carboplatin for a chemotherapy regimen for patients with metastatic, recurrent, or locally advanced non-small cell lung cancer (NSCLC), 46 chemotherapy-naïve patients with histologically confirmed stage IIIB or IV NSCLC were treated with 1250 mg/m2 of gemictabine on d 1 and 8, with carboplatin of AUC 6 additionally applied on d 1. This treatment was repeated every 3 wk. In all, a total of 215 chemotherapy courses were administered. The median age of the patients was 46, ranging from 33 to 83. Ten patients (22%) had an ECOG performance status of 2. Responses were observed objectively in 20 patients (43.5%) and maintained for a median of 7.4 mo. The median duration of progression-free and overall survivals were 5.0 and 12.3 mo, respectively. Neutropenia was frequently encountered, and gastrointestinal side effects, such as anorexia and nausea, were mostly predictable but manageable. One patient died of septic shock due to a complication with pneumonia while simultaneously trying to recover from myelosuppression. A subgroup consisting of patients aged 65 yr or older and/or PS 2 showed a outcome similar with the entire group of all patients involved in the study: response rate (43.5%), median PFS (4.6 months), median OS (12.3 months), and similar toxicity rate. After analyzing all the results, it was evident that a treatment of gemcitabine combined with carboplatin is an active and safe regimen for first-line treatment of advanced NSCLC. The results of the elderly and/or PS 2 patients were similar to those of the entire group of patients. 相似文献
