Abstract
A method includes assessing tumor margins and discriminating between tumor and non-tumor tissues by analyzing the compositional make-up of smoke produced during cautery resection of tissues.
Claims13
A method for discriminating between tumor tissue and non-tumor tissue in a subject in real-time, comprising:
- administering to the subject a tumor marker, the tumor marker being specific for tumor tissue;
- contacting tissue with a cautery to generate a cautery smoke;
- and
- analyzing the cautery smoke in real-time to detect the presence or absence of the tumor marker in the tissue contacted by the cautery;
- wherein:
- the presence of the tumor marker in the cautery smoke indicates contact of the cautery with tumor tissue, and the absence of the tumor marker in cautery smoke indicates contact of the cautery with non-tumor tissue.
3 more elements
A method for assessing the completeness of tumor resection in a subject, 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;
- 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 resection.
