cyberknife
Has anyone had any experience with cyberknife? I have been reading about it and it sound's very good. Supposedly is only 4 or 5 treatment's and is very accurate. Does'nt effect surrounding tissue.

Hi,

The Cyberknife represents a form of radiotherapy. For early stage lung cancer, radiation is recommended for patients who are unable to undergo surgery.

The experience with radiation shows conflicting data, on the average, patients do seem to do better, but if the target is 5 year survival - radiation did not seem to impact. In contrast, surgery shows better outcomes considering the average patient survival, and the 5 year survival. Current data cannot say whether surgery really is superior to radiation - however, with current experience - radiation cannot be recommended as equivalent to surgery. Therefore if the patient can tolerate the operation - this would be the way to go.

The Cyberknife is fairly new. The patients who have undergone treatment do not represent sufficient numbers to make a robust recommendation and the follow-up time is too short to get a feel of the 5 year outcomes. There is enough evidence to remark it is feasible and has an acceptable toxicity profile. Whether it really makes a difference in the long run - time will tell.

Of course, patients do not really have time to wait. If the surgical option is not acceptable, it would be better if you found an institution with an ongoing trial/large experience using this treatment modality.

I am trying to make a decision about my treatment. I have stage 3b adinocarcinoma non small cell lung cancer. I also have vonwillebrands type 2b which i take humate-p for as needed for bleeds.I have a low platelet count allways.I have been coughing up a lot of blood lately so i have been taking quite a lot of humate.I am trying to decide if i want to have chemo (taxater and carboplatinum) along with radiation or just radiation alone at least for a while.Don't know if i can tolerate both.They say surgery is not an option for me so i really can't see the purpose of doing both at once if there's not the chance of shrinking the tumor for surgery.

Hi,

I think the major consideration here indeed is what role your co-morbid disease would play. If that was absent - you could expect better results from concurrent treatment. Then again, there are still some proponents of giving the treatments (chemotherapy and radiotherapy) in sequence not concurrent - this may be the best for you.

Discuss specifics with your doctor. It would seem that your doctors would also need a conference of their own to weigh what options should be considered.

In what situations would Cyberknife not be recommended, i.e., size of tumour, location of tumour, etc.
