Outline of Final Research Achievements

Activatable fluorescent probe is a cell surface-associated enzyme that is overexpressed in various types of human cancers. In this study, 112 resected lung cancers (91 primary lung cancers and 21 metastatic lung cancers) and 4 pleural disseminated nodules were prospectively included. Of the primary lung cancers, 67% rapidly showed positive fluorescent activity. Positive fluorescent activity rates of the metastatic lung cancers and pleural disseminations were 71% and 100%, respectively.
We believe activatable fluorescent probe could aid surgeons in detecting tiny cancer during operation.
