ESTS guidelines for intraoperative lymph node staging in non-small cell lung cancer

摘要: The European Society of Thoracic Surgeons (ESTS) organized a workshop dealing with lymph node staging in non-small cell lung cancer. objective this was to develop guidelines for definitions and the surgical procedures intraoperative staging, pathologic evaluation resected nodes patients cancer (NSCLC). Relevant peer-reviewed publications on subjects, experience participants, opinion ESTS members contributing line, were used reach consensus. Systematic nodal dissection is recommended all cases ensure complete resection. Lobe-specific systematic acceptable peripheral squamous T1 tumors, if hilar interlobar are negative frozen section studies; it implies removal of, at least, three mediastinal from stations which subcarinal always included. Selected biopsies sampling justified prove involvement when resection not possible. Pathologic includes separately those remaining specimen. Sections done site gross abnormalities. If macroscopic inspection does detect any abnormal site, 2-mm slices longitudinal plane recommended. Routine search micrometastases or isolated tumor cells hematoxylin-eosin would be desirable. Randomized controlled trials evaluate adjuvant therapies these conditions adherence will standardize evaluation, improve help decide best therapy.
