Claims15
A method for assessing the completeness of tumor resection in a subject, the method comprising:
- introducing to the subject a marker that binds tumor tissue to a greater extent than non-tumor tissue;
- cauterizing along the boundaries of a tumor to generate a cautery smoke;
- and
- comparing a concentration of the marker in the cautery smoke to a predetermined concentration for the marker in a non-tumor tissue to assess the completeness of tumor resections;
- wherein the tumor is completely resected before said cauterizing the tissue along the boundaries of the tumor.
