To evaluate mediastinal lymph nodes in order to determine the stage of lung cancer cases, mediastinal lymphograpy was performed via a flexible bronchofiberscope under local anesthesia. The contrast medium was injected through NM 3K (Machida) needle into the subcarinal lymph node and the surrounding area of invasion. The contrast medium in the node was cleary recognized or PA and lateral chest X-ray films, tomograms and chest CT films in all cases. An anticancer drug, 30mg of peplomycin emulsion, was also injected into tho metastatic mediastinal lymph nodes during this procedure. A small amount of this emulsion was detected by bioassay of the extirpated lymph node a week after injection, and anticancer effects were also observed histopathologically.
