| Outline of Final Research Achievements |
We demonstrated that intraoperative autofluorescence findings of visceral pleura improved the diagnostic accuracy of visceral pleural invasion. The findings of visceral pleura using autofluorescence endoscopy and autofluorescence microscopy (hematoxylin and eosin stain specimen) were similar, and pathologic examination revealed that attenuation of autofluorescence at the visceral pleural invasion reflected the invasiveness of cancer. Collagen I and fibronectin were candidate proteins which were involved in the change of autofluorescence at the visceral pleura. In a retrospective study for resected lung cancer, there were significantly many cases with lymph node metastasis and skip metastasis within the cases with visceral pleural invasion. We could visualize subpleural lymphatic flow direct to N2 station which was seemed to be route of skip metastasis using indocyanine green fluorescence endoscopy.
