Transbronchial Needle Aspiration

Objective: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive, safe and accurate method for collecting samples from mediastinal and hilar lymph nodes. This study focused on the initial results obtained with EBUS-TBNA for lung cancer and lymph node staging at three teaching hospitals in Brazil. Methods: This was a retrospective analysis of patients diagnosed with lung cancer and submitted to EBUS-TBNA for mediastinal lymph node staging. The EBUS-TBNA procedures, which involved the use of an EBUS scope, an ultrasound processor, and a compatible, disposable 22 G needle, were performed while the patients were under general anesthesia. Results: Between January of 2011 and January of 2014, 149 patients underwent EBUS-TBNA for lymph node staging. The mean age was 66 ± 12 years, and 58% were male. A total of 407 lymph nodes were sampled by EBUS-TBNA. The most common types of lung neoplasm were adenocarcinoma (in 67%) and squamous cell carcinoma (in 24%). For lung cancer staging, EBUS-TBNA was found to have a sensitivity of 96%, a specificity of 100%, and a negative predictive value of 85%. Conclusions: We found EBUS-TBNA to be a safe and accurate method for lymph node staging in lung cancer patients.

Node Ratio

24 Background: Previous investigators have reported on the value of lymph node ratio (LNR, defined as the number of positive nodes divided by the total number of nodes assessed) in gastric adenocarcinoma (GAC) staging. Given the complexity of previously proposed staging systems, it has not gained widespread acceptance. The aim of our study was to offer a novel simplified approach to incorporating LNR into gastric cancer staging. Methods: 131 patients who underwent curative intent resection with lymphadenectomy for GAC between 1/00-6/11 were identified. Clinicopathologic factors were assessed. Primary outcome was overall survival (OS). Results: Median age was 64 yrs, 51% were male. Median tumor size was 3.5 cm, 67% were poorly differentiated, 20% had perineural invasion, 31% had lymphovascular invasion, and 6% had a positive margin. Locoregional nodal metastases were present in 59% (n=77, N0: 41%, N1: 18%, N2: 22%, N3a: 14%, N3b: 5%). Median number of lymph nodes (LN) assessed was 15.5. Mean FU was 27.3 mos, median OS was 29.3 mos. Median LNR was 0.4 (.04-1). Patients with LNR ≥0.4 had decreased OS as compared to patients with LNR <0.4 (15.1 vs 41.5 mos, p<0.0001); the survival of patients with LNR <0.4 was similar to that of node negative pts (48 mos, p=0.882). On Cox regression analysis, LNR ≥0.4 was more strongly associated with decreased OS (HR 3.09, 95%CI: 1.81-5.26; p<0.0001) compared to the AJCC 7th edition N stage (HR 1.36, 95%CI: 1.11-1.68; p=0.004). In the subset of patients who were inadequately staged and had <16 nodes examined, a LNR ≥0.4 was associated with reduced survival compared to a LNR <0.4 (17.3 vs 41.5 mos, p=.04). Conclusions: Compared to the current lymph node staging system, a lymph node ratio using 0.4 as the cutoff may more accurately predict survival outcomes. It seems to be particularly useful in patients who have inadequate nodal assessment. This simplified approach to lymph node ratio may be a more valuable staging tool than the current AJCC nodal staging system for gastric cancer and needs to be validated.
