Non-Invasive Treatment Freezes Kidney Tumors

March 6, 2007 - Research recently presented at the Society of Interventional Radiology's thirty-second Annual Scientific Meeting shows that the non-surgical image-guided treatment of kidney tumors, cryoablation which pushes argon gas to the tip of the probe and extracts heat from surrounding cells, freezing and killing the tumor, is as effective as the laparoscopic technique and results in a shorter hospital stay.

These CT images show placement of a 3-D fixed array implanted fiducial (3-D marker) at the time of oncoplastic tumor resection. The original LCTV (LCTVo) was retrospectively re-contoured by the radiation oncologist (LCTVro) and breast surgeon (LCTVbs). Thereafter, both re-contours were combined to create the collaborative LCTV (LCTVc), which required agreement of both the radiation oncologist and breast surgeon. Volume differences between the original LCTV (LCTVo) and the collaborative LCTVc were then evaluated, and demonstrated a mean and median reduction in LCTV.
