Abstract

We performed sentinel node identification using radioisotopic and/or dye techniques to determine the final indication after segmentectomy in cases with non-small cell lung cancer. Sentinel nodes were examined using intraoperative frozen sections stained with hematoxylin and eosin. We present 2 cases with completion lobectomy performed 7 and 11 days after segmentectomy because immunohistochemical staining of the sentinel nodes showed the presence of microscopic metastases that were not detected by the examination of intraoperative frozen sections.
