OBJECTIVES Invasive mediastinal staging is advised by guidelines in patients with resectable non-small cell lung cancer (NSCLC) and suspicious lymph nodes (cN1-3) or for central, FDG-non-avid or peripheral tumours >3 cm. Our objective was to assess current guideline adherence and consequent unforeseen N2 disease (uN2) in NSCLC patients having various indications for mediastinal staging. MATERIALS AND METHODS We analysed the Dutch Lung Cancer Audit - Surgery data of all patients who underwent a primary lung resection with lymph node dissection for NSCLC in 2017-2018. Based on the 2015 ESTS-ERS-ESGE guideline we assessed the use of initial endosonography and confirmatory mediastinoscopy as well as uN2 rates. RESULTS A total of 2238 patients were analysed. 43 % (95 %-CI: 41-45) underwent initial endosonography followed by a confirmatory mediastinoscopy in 44 % (95 %-CI:40-47) of them, resulting in a 19 % (95 %-CI: 17-20) rate of properly staged patient according to the guidelines. uN2 was demonstrated in 12.5 % (95 %-CI: 9.7-16.0) of correctly staged patients compared to 10.9 % (95 %-CI: 9.6-12.4) who were not (p = .36). The highest uN2 rate was found in cN1-3 patients who were not staged (23.0 %, 95 %-CI: 16.4-31.2) compared to 13.0 % (95 %-CI: 9.7-17.1) who were (p = .01). CONCLUSION Guideline adherence in Dutch NSCLC patients with an indication for invasive mediastinal staging is poor. The highest uN2 rate was found in unstaged cN1-3 patients, suggesting that this subgroup may benefit from an appropriate staging conform guidelines.

可切除的非小细胞肺癌患者坚持纵隔分期指南和不可预见的N2疾病:荷兰肺癌审核-手术在全国范围内的结果。

目的对于可切除的非小细胞肺癌(NSCLC)和可疑淋巴结(cN1-3)或中心性,FDG非病变或周围性肿瘤> 3 cm的患者,指南建议进行纵隔浸润分期。我们的目标是评估具有各种纵隔分期指征的NSCLC患者当前的指南依从性以及随之发生的不可预见的N2疾病(uN2)。材料和方法我们分析了2017-2018年接受NSCLC初次肺切除淋巴结清扫术的所有患者的《荷兰肺癌审核-手术》数据。根据2015年ESTS-ERS-ESGE指南,我们评估了初始超声内窥镜检查和确诊纵隔镜检查的使用率以及uN2率。结果共分析了2238例患者。43%(95%CI:41-45)接受了首次超声内镜检查,然后进行确诊的纵隔镜检查,其中44%(95%-CI:40-47),根据该标准,经过适当分期的患者比例为19%(95%-CI:17-20)准则。正确分期的患者中有12.5%(95%-CI:9.7-16.0)证实了uN2,而没有分期的患者为10​​.9%(95%-CI:9.6-12.4)(p = .36)。在未分期的cN1-3患者中发现最高的uN2发生率(23.0%,95%-CI:16.4-31.2),而未分期的cN1-3患者为13.0%(95%-CI:9.7-17.1)(p = .01) 。结论荷兰NSCLC患者的指南依从性较差,提示有创纵隔分期。在未分期的cN1-3患者中发现最高的uN2率,表明该亚组可能受益于适当的分期遵循指南。17-20)根据指南正确分期的患者比率。正确分期的患者中有12.5%(95%-CI:9.7-16.0)证实了uN2,而没有分期的患者为10​​.9%(95%-CI:9.6-12.4)(p = .36)。在未分期的cN1-3患者中发现最高的uN2发生率(23.0%,95%-CI:16.4-31.2),而未分期的cN1-3患者为13.0%(95%-CI:9.7-17.1)(p = .01) 。结论荷兰NSCLC患者的指南依从性较差,提示有创纵隔分期。在未分期的cN1-3患者中发现最高的uN2率,表明该亚组可能受益于适当的分期遵循指南。17-20)根据指南正确分期的患者比率。正确分期的患者中有12.5%(95%-CI:9.7-16.0)证实了uN2,而没有分期的患者为10​​.9%(95%-CI:9.6-12.4)(p = .36)。在未分期的cN1-3患者中发现最高的uN2发生率(23.0%,95%-CI:16.4-31.2),而未分期的cN1-3患者为13.0%(95%-CI:9.7-17.1)(p = .01) 。结论荷兰NSCLC患者的指南依从性较差,提示有创纵隔分期。在未分期的cN1-3患者中发现最高的uN2率,表明该亚组可能受益于适当的分期遵循指南。在未分期的cN1-3患者中发现最高的uN2发生率(23.0%,95%-CI:16.4-31.2),而未分期的cN1-3患者为13.0%(95%-CI:9.7-17.1)(p = .01) 。结论荷兰NSCLC患者的指南依从性较差,提示有创纵隔分期。在未分期的cN1-3患者中发现最高的uN2发生率,这表明该亚组可能受益于适当的分期遵循指南。在未分期的cN1-3患者中发现最高的uN2发生率(23.0%,95%-CI:16.4-31.2),而未分期的cN1-3患者为13.0%(95%-CI:9.7-17.1)(p = .01) 。结论荷兰NSCLC患者的指南依从性较差,提示有创纵隔分期。在未分期的cN1-3患者中发现最高的uN2发生率,这表明该亚组可能受益于适当的分期遵循指南。
