Hi Dr. Buddy Medbery, Greetings from China. I want to consult one question about the CK treatment, and if you could not replied please introduce the CK center contact, thanks. My farther in law has been treated by CK on the lung cancer for two times, in Aug. 2013 and Oct. 2015, and till now he is still in well status. During the CT checking in Sep. 2018 the doctor here said the tumor size doesn't have significantly changes, but the density looks higher. So the doctor suggest to have some kind of treatment, this doctor is not from CK treatment center just the Cancer center in the hospital. Now my question is, 1)Whether we need to do a PET to confirm the cancel cell still alive or not, since it's already 5 years since 2013, but no significant changes on the tumor size. 2) Whether possible to do the 3rd time treatment on the same position, I saw the response in the forum if the CK not control the tumor in the 1st time maybe not works for 2nd time, but in my father's case it works well. The only concern is whether the 3rd time will have same effect, whether it has the risk of produce Inflammation. Thank you very much for your response, and I hope you have opportunity to tourist in Hangzhou, the Paradise city in China which also holds the G20 conference, and have the company like Alibaba. thanks Raymond

I would recommend a PET scan. If the SUV is high (over about 5) the re-treatment could be considered. WE only did that once or twice but it was safe and effective in at least one case. They should not reduce the dose.

The tumor size is 3cmx2cm, BED85.6 Gy in 5 times , is this dose reasonable?

Hi Radsrus The PET CT has been done and result as following: The tumor in right lung now size is 4.5x2.8cm SUVMax 6.1, compares to year 2013 its a bit bigger. and there is another one in mediastinal lymph nodes, size 0.9 x 0.6cm, Suvmax 5.4. May I consult that which Gy is suitable in 3rd time treatment, its very important to us since I have learned in some case radiation pneumonitis cause serious problem. My farther is 67 years old and left lung has operations in 2010. Personally he dont want to do chemotherapy,and there is no Molecular targeted drug suitable to him. So Cyber Knife is the only choice to save the life at the moment. Anyhow, appreciate for it. Thanks for answering the question of Gy volume.

I would not re-treat in this case because of the mediastinal node involvement.

mediastinal node involvement normally means stage III or IV that should be the reason? the exactly description is mediasrinal node near the hilus of the lung has problem. Considering from the time that tumor found in 2013 even now is late stage its not surprised, but since two times treatment by CK generally speaking its still well controlled. Does it possible to use CK + Chemotherapy?

I would probably start with the chemotherapy. If good response, could consider treatment as you planned. If not, then CK won't help
