Abstract: A surgical marking system has been developed that can be easily used during surgery to mark an area of the body, e.g., the margins of a tumor resection cavity, for post-operative radiation therapy or subsequent evaluation by CT, MRI, or radiography. This marker system is formed as a semi-liquid solution that is expelled into the resection margins as a stream that quickly polymerizes in situ into a solid or semi-solid strand that adheres to the surrounding tissue. Several of these strands may be placed to outline the cavity surface. One or more of the polymerizing agents contain one or more imageable markers for post-operative imaging or therapy. The method allows a surgeon to outline the margins of a surgical site in all directions. In addition, radioactive isotopes or therapeutic drugs can be added to the marker strands for in situ therapy.
