Can Cyberknife eliminate tumors? Petscan?

Hi Margaret. Teddy’s B.R. this month was .08, pretty dang good. Goes to show again that the more we know…the more we don’t know. I had to fight for his PET in December and now the approval came early for the next one! Go figure.
He is supposed to get one in March according to the Radiologist but the Oncologist just ordered one for February when his last one was December 28th. Also an MRI to check the scar tissue etc. I have to call him today and see if he meant to have it so soon again instead of March. I am having mine the 29th of this month. Since I have never had one and I now have this other rare cancer (GIST) he wanted me to ahve one also. I wonder if they give a 2 for 1???

Adam, Teddy is having that problem now. His CA19 has climbed to 375 from 11 in September. We know there are 2 new small tumors but the PET showed them as shrinking. We don’t know why they are but we will take it. He is having an MRI early next month to see if it is scar tissue in his Bile Ducts as his Bilierubin is better than normal. An MRI will show scar tissue where the PET does not show it.

Too, too bad. Teddy could not be here without it!

Marion, did they say why the trial of cyber knife was halted at UCSF.

Adam, my husband, Teddy had cyber knife a year ago. His was not on the liver but where his duodenum used to be. The tumor must be under 7cm and his was 7cm. He had 25 radiation treatments to shrink it to 6cm and then the cyber knife. It is amazing. Only 3 treatments and he was done. I am not good at medical terms but first you get 4 little gold “rods” injected into the area to “mark” the tumor and guide the laser. Then this laser only “zaps” exactly where that tumor is and does not affect any other area. Once the tumor is hit with the laser it begins to die immediately. It will stop growing and in a year appears to be like a piece of shriveled up ash. Not sure if it disappears totally but it doesn’t matter, it will not affect anything else. Teddy now has 2 very small tumors one near a kidney and one outside the liver. They are so small nothing can be done yet and in fact seem to be shrinking.
Also we just went through the question of PET vs MRI. a PET Scan lights up any tiny or large cancer area. An MRI “defines” it. If you go to our search engine at the top of the page and type in anything you are questioning you will get all the posts up that pertain to that subject. I have posted a ton on cyber knife.
My humble opinion is that Doctors who put down cyber knife probably don’t know enough about it. Believe it or not we have found doctors who had never heard of it! Perhaps a second opinion is in order. Curious, but have they mentioned scar tissue as causing the blockage? Scar tissue does not show on a PET but shows on an MRI.
