International association for the study of lung cancer map, Wang lymph node map and rapid on-site evaluation in transbronchial needle aspiration

Abstract

The invaluable role of transbronchial needle aspiration (TBNA) in the diagnosis and staging of mediastinal adenopathy and lung cancer has been well established. Different lymph nodes regional nomenclatures and maps had been described over the years. The international association for the study of lung cancer (IASLC) and Wang's maps complement each other benefiting patients with lung cancer. In this article we briefly reviewed the roles of IALSC, Wang's maps and ROSE in TBNA.

Diagnostic value of rapid on-site evaluation in interventional pulmonology

“…For example, a retrospective study of Liu found that ROSE was helpful in guiding the operation of EBUS-TBNA, but did not improve the rate of pathological diagnosis of TBNA. [ 15 ] Another study also found that ROSE helped to ensure the validity and adequacy of samples, and can provide optimal samples for flow cytometry, immunostaining, and molecular pathology, but it had no significant effect on the diagnosis rate. [ 16 ] According to the study of Madan, in the 2 EBUS-TBNA groups, the use of ROSE had no significant effect on the diagnosis rate.…”

Role of intrapulmonary lymph node retrieval for pathological examination in resectable non-small cell lung cancer

“…Current studies and guidelines suggest that systematic LN dissection or sampling should be performed in resectable NSCLC (3,4). It is indicated that mediastinal LN (stations 2-9 or N2) (5,6) should be dissected when performing curative pulmonary resection in order to accurately determine tumor stage. For intrapulmonary LN or N1, stations 10-12 are usually dissected because they are easily identified and collected; however, the dissection of stations 13-14 is quite difficult and requires adequate training (7).…”
