非小细胞肺癌患者术中发现胸膜播散的预后分析

目的评估手术切除肿瘤对非小细胞肺癌(NSCLC)伴恶性胸膜播散患者预后的影响。 方法收集2011年1月至2015年12月上海市胸科医院NSCLC手术患者的临床资料,将术中意外发现胸膜播散的患者纳入研究。 结果通过术中或术后病理学检查,共有160例NSCLC患者被诊断为胸膜播散。71例(44.4%)仅行胸膜结节活检(活检组),89例(55.6%)行原发肿瘤切除术(切除组)。中位无进展生存期(PFS)和总生存期OS)分别为13个月和41个月,3、5年的无进展生存率分别为13.1%和5.7%,总生存率分别为56.0%和28.7%。切除组患者的PFS和OS均明显优于活检组(19个月vs 10个月,P＝0.000;48个月vs 33个月,P＝0.000)。切除组的3、5年无进展生存率和总生存率均高于活检组(20.8% vs 3.2%,10.8% vs 0;67.8% vs 41.0%,37.7% vs 18.2%)。接受亚肺叶切除术与肺叶切除术患者的生存差异无统计学意义(P＝0.34)。单因素和多因素分析结果显示：辅助靶向治疗、无恶性胸腔积液、T1/T2期和N0期是独立的预后因素。 结论术中诊断为NSCLC伴胸膜播散的患者可通过手术切除原发肿瘤和包括靶向治疗在内的多学科治疗获益。辅助靶向治疗、无恶性胸腔积液、低T分期、低N分期患者的预后较好。在可行的情况下,楔形切除术可能是一个合适的选择,虽然不同手术方式亚组的预后差异无统计学意义,但其创伤更小。     

直径≤3cm的周围型非小细胞肺癌纵隔淋巴结转移规律的初步研究

目的探讨直径≤3cm的周围型非小细胞肺癌(non-small cell lung cancer,NSCLC)纵隔淋巴结转移的情况,分析早期周围型NSCLC纵隔淋巴结转移的规律。方法 2000年1月1日～2008年12月31日治疗直径≤3cm的周围型NSCLC161例,男89例,女72例,年龄(63.4±10.7)岁,行肺叶切除或肺局限性切除加系统性纵隔淋巴结清扫术,分析其临床特征、病理特点及纵隔淋巴结转移规律。结果全组手术顺利,无死亡及严重并发症发生。肺叶切除153例,肺楔形切除7例,肺段切除1例。全组共清扫淋巴结2456枚,平均每例4.5±1.6组、13.1±7.3枚。术后病理:腺癌99例,鳞癌30例,肺泡细胞癌19例,其他类型肺癌13例。术后TNM分期:ⅠA期50例,ⅠB期62例,ⅡA期6例,ⅡB期10例,ⅢA期33例。N1组淋巴结转移率为23.6%(38/161),N2组转移率为20.5%(33/161),其中隆突下淋巴结转移率为8.1%(13/161),跳跃式纵隔转移率为6.8%(11/161),全组未发现下纵隔淋巴结转移。肺泡细胞癌及直径≤2cm的鳞癌、直径≤1cm的腺癌均无pN2转移。上肺癌发生pN2转移时上纵隔100%(19/19)受累,其中21.1%(4/19)同时伴有隆突下淋巴结转移;下肺癌则除主要转移至隆突下外(64.3%,9/14),还常直接单独转移至上纵隔(35.7%,5/14)。转移的纵隔淋巴结左肺癌主要分布在第5、6、7组,右肺癌主要分布在第3、4、7组。结论对于直径≤3cm的周围型NSCLC,肿瘤直径越大,其纵隔淋巴结转移率越高,肺泡细胞癌、直径≤2cm的鳞癌和≤1cm的腺癌其纵隔淋巴结转移率相对较低;上肺癌主要转移在上纵隔,下肺癌则隆突下及上纵隔均可转移;第5、6、7组淋巴结是左肺癌主要转移的位置,第3、4、7组是右肺癌主要转移的位置,术中应重点清扫。     

非小细胞肺癌术后多系统转移与预后的相关性分析

目的评估非小细胞肺癌根治性切除术后转移规律与预后之间的相关性。方法回顾性分析2005年1月至2011年12月于我院胸外科行根治性肺叶切除的非小细胞肺癌患者94例的临床资料,分析术后转移规律与预后之间的关系。男53例、女41例,年龄62(57~76)岁。结果全组两年以后发生转移者占52.12%(49/94),90.43%(85/94)患者发生单系统转移。最常见的术后转移部位为肺组织(38/94,40.42%)、骨转移(27/94,28.72%)、脑转移(24/94,25.53%)。随访终点94例入组患者总生存率为41.5%。单系统转移患者和多系统转移患者的生存率分别为45.9%和0.0%(P0.001)。两年内发生单系统转移患者和转移时间超过两年患者组的总生存率分别为53.3%和30.6%(Cox P=0.130,Breslow P=0.014)。Cox回归对与生存率相关因素进行分析,结果显示TNM分期为Ⅰ~Ⅱ期(P=0.003)以及单系统转移(P0.001)与生存率呈正相关。结论非小细胞肺癌根治性切除术后容易发生肺组织、骨骼以及脑转移,术后发生多系统转移的患者预后较差。     

空洞型非小细胞肺癌的预后分析

Objective To explore the survival and prognostic status of the cavitating non-small cell lung cancer. Methods A total 42 surgically treated patients with cavitating non-small cell lung cancer were studied retrospectively. Kaplan-Meiei was used to analyze the relationship between the prognostic factors and survival time. The cavitaing non-small cell lung cancer were matched 1:2 to the patients with non-small cell lung cancer that there is no cavity in X-ray, for gender, age, histology, lymph nodes dissection, stage, and whether receiving chemotherapy. The two groups were compared using the Log-rank test. Results The overall 1, 3, 5- year- survival rates for cavitating non-small cell lung cancer were 76.2%, 28.6%, and 14.7%, respectively. The diameter of the cavity and lymph nodes status significantly influenced syrvivals. 1he overall syrvival between the two groups of patients showed no sig- nificant differences (P=0.075). But the factors of women(P=O.040), younger than 60 years(P =0.032), NO of the lymph nodes dissection group(P=0.046), and staging Ⅰ were significantly influenced 5-year survivals(P=0.048). Conclusion The diameter of the cavity and lymph nodes status were correlated with the survival. The carcinomatous cavity are important prognosis factors for the nan-retail cell lung cancer patients of younger than 60 years, negative of lymph nodes dissection and staging Ⅰ , but whether the carci- nomtous cavity are important prognosis factors for the non-small cell lung cancer patients of woman was not determined.

直径小于2cm实性非小细胞肺癌的淋巴结转移及危险因素分析

目的观察直径小于2 cm实性非小细胞肺癌(NSCLC)的淋巴结转移情况,并分析淋巴结转移的危险因素。方法回顾性分析2005年10月至2016年9月间在我院行肺叶切除术及系统淋巴结清扫的611例直径小于2 cm的实性NSCLC患者的临床资料,其中男322例、女289例,平均年龄25~84(58.8±10.0)岁。并以logistic回归模型分析淋巴结转移的危险因素。结果 611例患者中,发生淋巴结转移136例(22.3%),未发生淋巴结转移475例(77.7%)。单因素分析结果显示,性别(P=0.032)、分化程度(P0.001)和病变位置(P=0.047)均与淋巴结转移有关。多因素分析结果显示,分化程度是影响直径小于2 cm实性NSCLC淋巴结转移的独立因素(P0.001)。结论直径小于2 cm的实性NSCLC,仍有较高的淋巴结转移率,且病理分化程度低是其发生淋巴结转移的独立危险因素。对于直径小于2 cm的实性NSCLC仍应行系统性淋巴结清扫,并慎行亚肺叶切除。     

直径大于5 cm非小细胞肺癌行全胸腔镜肺叶切除术后放置单胸管引流的可行性分析

目的探讨直径 5 cm非小细胞肺癌行全胸腔镜肺叶切除术后放置单胸管引流的可行性。方法行全胸腔镜肺叶切除术的非小细胞肺癌病人120例,直径均 5 cm,根据住院先后顺序编号,再按随机数字表分为两组;对照组60例,术后放置双胸管引流;观察组60例,术后放置单胸管引流;比较两组胸腔引流量、胸腔引流时间、拔管后胸腔穿刺抽液次数、术后住院时间、术后第1天及30天的视觉模拟(visual analogue scale/score,VAS)评分、术后第1天及3天的肺扩张度、再次置管率、切口并发症发生率、胸腔感染率、胸腔积气积液率、术后30天死亡率。结果两组胸腔引流量、胸腔引流时间、拔管后胸腔穿刺抽液次数比较,差异均无统计学意义(P 0. 05);观察组术后住院时间为(5. 12±0. 24)天,显著短于对照组的(5. 73±0. 57)天,差异有统计学意义(P 0. 05);观察组术后第1天及30天的VAS评分分别为(3. 96±0. 07)分、(1. 27±0. 02)分,对照组分别为(4. 51±0. 04)分、(1. 69±0. 02)分,两组术后第1天及30天的VAS评分比较,差异均有统计学意义(P 0. 05);两组术后第1天及3天的肺扩张度比较,差异均无统计学意义(P 0. 05);观察组再次置管率为0、切口并发症发生率为3. 33%、胸腔感染率为1. 67%、胸腔积气积液率为1. 67%、术后30天,死亡率为0,对照组分别为0、6. 67%、3. 33%、0、0,两组再次置管率及相关并发症发生情况比较,差异均无统计学意义(P 0. 05)。结论直径 5 cm的非小细胞肺癌病人行全胸腔镜肺叶切除术后放置单胸管引流是可行的,引流效果及安全性应值得肯定,在减轻病人术后疼痛方面较双胸管引流更有优势。     

侵犯脊柱的非小细胞肺癌外科治疗进展

正侵犯脊柱的非小细胞肺癌(non-small cell lung cancer,NSCLC),在第7版肺癌TNM分期中,归为T4期肿瘤,过去曾被视为手术禁忌~([1])。随着脊柱外科技术的联合应用,符合肿瘤学原则的整块手术切除得以实现,明显提高了侵犯脊柱的NSCLC患者的生存时间~([2-7])。一、历史沿革肺沟各处的NSCLC均可侵犯脊柱,但胸廓入口处的NSCLC由于其特殊的解剖位置,更容易侵犯脊柱,     

表皮生长因子受体基因突变非小细胞肺癌腹膜转移5例预后分析

目的分析表皮生长因子受体(EGFR)基因突变阳性的非小细胞肺癌(NSCLC)腹膜转移患者的预后因素。 方法收集2014—2019年收治的EGFR突变阳性NSCLC腹膜转移患者的临床资料。主要观察和分析指标为中位生存期(mOS )，其中mOS1表示从确诊不可切除的中晚期肺癌开始或根治性切除术后发生复发和/或转移开始接受一线酪氨酸激酶抑制剂(TKI)治疗至出现肿瘤耐药的时间，mOS2表示从确诊腹膜转移开始至死亡或随访终点的时间。 结果共收集5例患者，均为异时性转移，第一代TKI治疗耐药后出现腹膜转移。耐药后再次基因检测发现EGFR T790M突变阳性3例。mOS1：总体为14.4个月；EGFR 19外显子突变者为18.8个月，21外显子突变者为16.3个月，18外显子突变者为15.6个月。mOS2：总体为7.5个月；EGFR T790M突变阳性者为10.4个月，EGFR T790M突变阴性者为5.2个月；接受靶向治疗联合血管抑制剂治疗者为12.6个月，单纯靶向治疗者为9.3个月，血管抑制剂联合化学治疗者为6.2个月，单纯血管抑制剂治疗者为4.2个月。 结论EGFR突变阳性NSCLC患者腹膜转移后再次行基因检测非常必要，靶向治疗联合血管抑制剂治疗策略可能使患者获得更长的生存期。     

Ⅰ期非小细胞肺癌预后的影响因素分析

非小细胞肺癌(NSCLC)是当今发病率和病死率最高的恶性肿瘤之一.近年来,随着各种诊断技术的改进,早期非小细胞肺癌的诊断率也逐年提高,目前对于Ⅰ期非小细胞肺癌的治疗主要以手术为主,预后较其他期别的非小细胞肺癌相对较好[1],但5年生存率仍然仅仅停留在55%～72%,显示Ⅰ期非小细胞肺癌中存在着预后较差的亚组.
