44%的病理性淋巴结阴性(pN 0)非小细胞肺癌(NSCLC)患者在根治性手术后5年内死亡。病理淋巴结检查实践中的异质性引起了对这些患者淋巴结分期准确性的关注。我们假设检查的淋巴结数量与漏诊淋巴结转移的概率之间存在相互关系,并试图确定与pN 0 NSCLC最低死亡风险相关的淋巴结数量。我们分析了1998年至2009年美国监测、流行病学和最终结果数据库中首次原发pN 0 NSCLC的切除术,生存期更新至2009年12月31日。在24,650名符合条件的患者中,随着更多淋巴结的检查,死亡风险显著降低。淋巴结数在18 - 21个的患者死亡风险最低。全因死亡率的风险比为0.65,95%置信区间为0.57 - 0.73;肺癌特异性死亡率为0.62,0.53 - 0.73;两者p<0.001。检查的淋巴结的中位数仅为6个。淋巴结评估福尔斯在切除的“pN 0 NSCLC”患者中远远达不到最佳效果,这增加了低估长期死亡风险的可能性,并且未能确定术后辅助治疗的候选者。这是一个重大的质量差距,需要采取纠正措施。
Forty four percent of patients with pathologic node negative (pN0) non-small cell lung cancer (NSCLC) die within 5 years of curative-intent surgery. Heterogeneity in pathologic nodal examination practice raises concerns about the accuracy of nodal staging in these patients. We hypothesized a reciprocal relationship between the number of lymph nodes examined and probability of missed lymph node metastasis, and sought to identify the number of lymph nodes associated with the lowest mortality risk in pN0 NSCLC. We analyzed resections for first primary, pN0 NSCLC in the United States Surveillance, Epidemiology, and End Results database from 1998 to 2009, with survival updated to December 31, 2009. In the 24,650 eligible patients, there was a significant, sequential reduction in mortality risk with examination of more lymph nodes. The lowest mortality risk occurred in those with 18 – 21 lymph nodes. Hazard ratio for all-cause mortality was 0.65, 95% confidence interval 0.57 – 0.73; for lung cancer specific mortality, 0.62, 0.53 – 0.73; p<.001 for both. The median number of lymph nodes examined was only 6. Lymph node evaluation falls far short of optimal in patients with resected ‘pN0 NSCLC’, raising the odds of under-estimation of long-term mortality risk, and failure to identify candidates for post-operative adjuvant therapy. This represents a major quality gap, for which corrective intervention is warranted.
