Introduction

Spread through air spaces (STAS) is a form of invasion wherein tumor cells extend beyond the tumor edge within the lung parenchyma. In lung adenocarcinoma (ADC), we investigated the (1) association between STAS and procedure-specific outcomes (sublobar resection and lobectomy), (2) effect of surgical margin-to-tumor diameter ratio in STAS-positive patients, and (3) potential utility of frozen sections (FSs) for detecting STAS intraoperatively.

Methods

We investigated 1497 patients who underwent lobectomy (n = 970) or sublobar resection (n = 527) for T1N0M0 lung ADC after propensity score matching. Outcomes were analyzed by using a competing risks approach. The effect of margin-to-tumor ratio on recurrence pattern (locoregional and distant) was investigated in patients who underwent sublobar resection. Five pathologists evaluated the feasibility of intraoperatively identifying STAS by using FSs (sensitivity, specificity, and interrater reliability).

Results

On multivariable analysis after propensity score matching (349 pairs/procedure), sublobar resection was significantly associated with recurrence (subhazard ratio = 2.84 [p < 0.001]) and lung cancer–specific death (subhazard ratio = 2.63 [p = 0.021]) in patients with STAS but not in those without STAS. Patients with STAS who underwent sublobar resection had a higher risk of locoregional recurrence regardless of margin-to-tumor ratio (for a margin-to-tumor ratio of ≥1 versus <1, the 5-year cumulative incidence of recurrence rates were 16% and 25%, respectively); among patients without STAS, locoregional recurrences occurred in patients with margin-to-tumor ratio lower than 1 (a 5-year cumulative incidence of recurrence rate of 7%). The sensitivity and specificity for detecting STAS by use of FSs were 71% and 92%, with substantial interrater reliability (Gwet’s AC1, 0.67).

Conclusions

In patients with T1 lung ADC with STAS, lobectomy was associated with better outcomes than sublobar resection was. Pathologists can recognize STAS on FSs.  相似文献

Aims: The purpose of this study was to identify the risk factors for major adverse events of VATS (Video-Assisted Thoracic Surgery) lobectomy for primary lung cancer.Methods: 1806 Patients (1032 males, 57.1%) planned to undergo VATS lobectomy for stage IA-IIIA lung cancer from July 2007 to June 2012. The Thoracic Morbidity and Mortality Classification TM&M system was used to evaluate the presence and severity of complications. Postoperative complications were observed during a 30-day follow up. Univariate and multivariate analysis were used to analyze the independent risk factors for major adverse events.Results: Successful rate of VATS lobectomy was 97.6% (1763/1806). Major complications occurred in 129 patients (7.3%), with a mortality of 0.3% (5/1763). Pulmonary complications contribute up to 90.7% of the major complications and 80% of mortality. Logistic regression indicated that comorbidities, elder age ≥70y, operative time ≥240min and hybrid VATS were predictors for major adverse events (P<0.05). Hybrid and converted VATS lobectomy result in higher major adverse events compared with complete VATS, 15.1%, 20.9% and 7.4% respectively (P=0.013).Conclusions: The overall complication rate and mortality of VATS lobectomy are low, while major complications sometimes occur. Pulmonary complications are the most common major complications and cause of mortality. Age ≥70y, comorbidities, operative time ≥240min and Hybrid VATS are predictors of major adverse events.  相似文献

Open in a separate windowOBJECTIVESThe aim of this study was to determine whether the preoperative thoracic muscle mass is associated with postoperative outcomes in patients undergoing lobectomy via thoracotomy for lung cancer.METHODSConsecutive patients undergoing lobectomy were retrospectively reviewed. The thoracic muscle mass index (TMMI) was obtained at the level of the fifth thoracic vertebra on preoperative thoracic computed tomography (CT). Patients were analysed comparatively by being dividing into low and high muscle index groups by the median of sex-specific TMMI. The primary outcomes were the incidence of any or postoperative pulmonary complications. The secondary outcomes were postoperative intensive care unit (ICU) admission, length of stay (LOS) in the ICU, total hospital LOS, readmission and mortality.RESULTSThe study population consisted of 120 patients (63.6 ± 9.8 years; 74% male). Each groups included 60 patients. Major complications occurred in 28.3% (34/120) and readmission in 18.3% (22/120) of patients. The adjusted multivariable analysis showed that each unit increase in TMMI (cm2/m2) was independently associated with the rates of less any complications [odds ratio (OR) 0.92, P = 0.014], pulmonary complications (OR 0.27, P = 0.019), ICU admission (OR 0.76, P = 0.031), hospitalization for >6 days (OR 0.90, P = 0.008) and readmission (OR 0.93, P = 0.029).CONCLUSIONSLow TMMI obtained from the preoperative thoracic CT is an independent predictor of postoperative adverse outcomes in patients following lobectomy via thoracotomy for lung cancer. TMMI measurements may contribute to the development of preoperative risk stratification studies in the future.  相似文献

目的评价各型胆肠内引流术在治疗肝内胆管结石中的作用。方法回顾性分析我院1982~2001年手术治疗的1232例肝内胆管结石病人资料,对其中的334例胆肠内引流术病例的适应证、方法及其效果进行总结。结果胆肠内引流组发生术后并发症57例(发生率17.1%)。死亡5例,分别死于腹腔内出血、吻合口瘘及肝功能衰竭等。近5年中因肝内胆管结石而行胆肠内引流术者无1例死亡及发生严重并发症。结论胆肠内引流术在肝内胆管结石的处理上有重要的作用,但随着肝切除在临床上推广,胆肠内引流术逐步减少,其适应证亦愈来愈严格;它对不能切除的胆管狭窄有重要意义;胆总管十二指肠内引流术治疗肝内胆管结石的方法应摒弃。  相似文献

目的探讨全胸腔镜下肺叶切除治疗支气管扩张症的安全性、可行性和有效性。方法回顾性分析我中心2007年4月~2009年11月完成的24例全胸腔镜肺叶切除手术治疗支气管扩张症的临床资料。全胸腔镜下解剖性肺叶切除,不牵开肋骨,以切割缝合器分别处理肺血管和支气管。如遇严重粘连或出血等则中转开胸手术。记录手术时间、出血量、术后带管时间以及并发症等。结果全组中2例(8.3%)因为胸腔内粘连重,叶间裂分化差或肺门处严重粘连并有大量迂曲扩张的血管,镜下处理困难而中转开胸行VATS辅助小切口手术。余22例在全胸腔镜下完成,肺切除范围包括右肺上叶1例,右肺中叶1例,右肺下叶3例,左肺上叶2例,左肺下叶13例,左肺下叶+左肺上叶舌段1例,左肺下叶+右肺中叶1例。手术时间(173.6±57.1)min(80~280min),出血量(173.9±65.9)ml(50~300ml),术后带管时间(6.1±3.8)d(2~19d),术后住院时间(8.6±3.9)d(4~22d)。术后病理均符合支气管扩张症改变。无围手术期死亡。并发症4例,均为肺持续漏气7d,引流7~19d后自愈拔除胸腔引流管。全组随访1~31个月,平均13.7月,其中13例12个月。15例(62.5%)术后咳痰或咯血症状完全消失,7例(29.2%)痰量明显减少,但仍间断有咳痰或咯血等症状。2例(8.3%)咯血量或痰量较前无明显变化。结论全胸腔镜肺叶切除术是治疗支气管扩张症的一种安全有效的方法 。  相似文献
