Essentially, Cyberknife is a linear accelerator mounted on a robotic platform that can move independently in all directions in 3D space to direct a tightly collimated x-ray beam at diseased tissue. By coupling this capability with real-time imaging and computer control that can compensate for slight patient movements many times per second, such as due to breathing, twitching, or coughing, the Cyberknife platform can safely direct radiation to tumor locations in the body where even a very skilled surgeon would likely never go such as near major blood vessels, nerves or other vital organs.

The Cyberknife is another capable SRS system for treat-
ing brain lesions, but its design has expanded SRS for
lesions anywhere in the body, including structures that
move with respiration.
Your husband most likely had stage IV and not stage III cancer even at the time of diagnosis. The enlarged celica nodes represent metastasis. It is very common for metastatsis to shrink with chemo and then start growing again.
-cyberknife is not an option. it is used in very special circumstances like a single area of metastasis in the brain. I have never seen anyone use cyberknife for colon metastasis in the abdomen.
-He has already received Folfox. Next step would be something containing irinotecaan, like FoLFIRI. Avastin may be continued. Unfortunately the disese is not curable but hopefully will be controlled for some time.
