Sentinel lymph node procedure
After careful mobilization of the affected colon segment, isosulfan blue 1% is injected in vivo into the subserosa circumferentially around the tumor. Lymph nodes in the mesentery staining blue within the first minutes are marked as SLN. The procedure is followed by a resection of the affected colon segment with standard lymphadenectomy.
Bone marrow aspiration
Prior to surgery, bone marrow is aspirated from both iliac crests. Bone marrow aspirates are analyzed for the presence of occult metastatic colon cancer cells.
