Is cyberknife possible for this situation?

My dad (74 yrs old) has RCC with mets to the liver, lymph nodes, and lung. I wanted to find out as much as possible about this procedure to determine whether it is an option. He already tried the Torisel chemo without much success and radiation to the lung only, but the tumor there shrank slightly while the tumors in the other areas grew. Tumor sizes - right kidney 8.4x11.7cm Nodules in lungs - multiple ones ranging b/w 2 to 4 mm Lymph nodes - 2.2 x 2.2 cm Liver = 9.0 x 6.6cm The doctors stated that surgery is not an option since the cancer has spread. They next recommended Sutent as the chemo drug to try, but they stated there is a high possibility of life-threatening bleeding that can occur since my dad has had a history of coughing up blood before. Considering that factor, we felt it was too risky to try Sutent. I'd like to find out if cyberknife can work in this case. Could cyberknife be used??? It sounds so promising that I wish it is an option.

There is some data suggesting that removing the primary tumor makes the mets respond better. CK would be difficult in this situation. That liver tumor is big. Perhaps radiolabelled spheres would be a better option. The lymph nodes are not likely to cause major problems soon. The lung tumors are too small to make it worth treating them. If a small number became problematic, then they could be treated.
