Re: Comparative radiation exposure

I had RT with Dr. Tripuraneni at Scripps, San Diego on my right hand. He did 5 days x 2 gy for two consecutive weeks for a total of 20 Gy. It was effective. Stopped the progression of my disease. No more nodules in the irradiated area.

On left hand at Loma Linda UMC, Dr. Katerelos did 3 Gy x 7 days in a two week period. It stopped the progression. My choice is less is better if it works. It worked for me.

I go Monday to for consultation with Dr. Katerelos about Ledderhose on my right foot. We'll see what he thinks.

Why did I switch to Dr. Katerelos? 2 reasons: #1 - the medical billing to Medicare at Scripps left much to be desired. They did not know how to or didn't want to bother to appeal a denial by Medicare. LLUMC was very well versed on Medicare and insurance in general and took care of everything. Between Medicare and my supplemental, all was covered.

#2 - Loma Linda is 30 minutes/25 miles away vs. 2 hours/85 miles to San Diego/La Jolla.

By the way, I loved Dr. Tripuraneni. There should not have been a billing issue.

Re: Comparative radiation exposure

The variable treatment regimens is interesting. The radiologist said that he uses the published schedule of 5x3Gy followed by a six week break and a further 5x3Gy but cannot see any logic in this. Other more convenient/shorter schedules clearly work.

Re: Comparative radiation exposure

Hi Australia Calling.
There is good reason to wait as in my case back in 2007 I had both my hands and feet treated by Prof. Seegenschmiedt in Germany. My right hand only received one protocol of 5X 3 Gy Total of 15 Gy. whereas my left hand had 30 Gy. Another reason is that it allows the oncologist a chance to examine any new reoccurrence of the disease.

Re: Comparative radiation exposure

Another point, additional to newman's comment, is that the fractioning gives the skin and connective tissue time to recover and reducing side effects.

Short and Low is Beautiful as long as it works !


Regarding other "Proliferative Disorders" like keloids it is known that relatively high radiation doses are required to influence the fibrous tissues, while lower doses are required to influence "Inflammatory Disorders"

If Dupuytrens Disease dvelops in a two step-model from "injury" --> to "local inflammation" --> to "local repair"
then both dose concepts might be useful: the very early cases may require "lower doses" than the more advanced cases which show proliferating fibroblasts ?!

Interesting publication and abstract under this LINK:

http://www.ncbi.nlm.nih.gov/pubmed/16254707

Would be nice to contact an experienced radiation therapist on that topic

The Dr. who did my RT said the exposure was so minimal that I could have it done again next year if needed.

callie, are you referring to another RT regimen totaling 30 Gy bringing the total lifetime to 60 Gy?

I had 10x3 on the NHS at Poole and the doctor said that we only get one shot at this which I took to mean that a second treatment on the same hand would be out of the question. 60 Gy is getting into dangerous territory IMHO
