A LIGHT AND ELECTRON-MICROSCOPIC STUDY OF LUNG CANCERS - CLINICAL IMPLICATIONS

This study consists of 71 consecutive surgically resected specimens of lung cancer which were submitted for both light and electron microsco pic studies. Eleven of the 71 cancers found in the resected specimens and originally diagnosed by light microscopy had to be reclassified wh en studied by electron microscopy. All of the reclassified cancers wer e either poorly differentiated or undifferentiated tumors. This findin g enables one to better select and suspect those cancers which are mor e likely to be in need of electron microscopic study.
