Radiation-different treatment plans

Hi, I’m thinking about RT for my dupuytrens . From reading and telephone conversations with radiation clinics there seems to be several different ways of administering the RT. Here are three that I have found.
1. 5 days of RT, 6-8 weeks off, 5 days of RT.
2. 7 treatments of RT in 5 days. Basically Monday through Friday, with 2 treatments on Tuesday and Thursday.
3. 5 days of RT, weekend, 5 days of RT
Treatment plan #1 was perfected by the Germans, they seem to have the most experience using RT for dupuytrens. There are clinics in the US that follow this protocol, but they are out of my area.
Treatment plan #2 is used at the University of Oklahoma. It only takes a week.
Treatment plan #3 is used at Scripps hospital in San Diego. I live in San Diego.
So, are there any significant differences in these treatment protocals? My gut instinct is to trust the German protocol, because they have the most experience and published material/studies. There has to be a real good reason to break up the treatments with a 6-8 week break.
The Dr. I spoke with at U of O said there are radiation equivalency charts, which dictate different treatment protocol that are all basically equal. He said I should not concern myself with the differences.
Dupuytrens has badly affected the strength and dexterity of my left hand,( it has literally started shrinking) if the same thing happens to my right hand I would be out of work. I am definitely considering RT, but need to know which plan to pick.
Thank You
Bob

Re: Radiation-different treatment plans

Bob,

differences are due to two aspects

a) reducing total dose to minimize radiation exposure
Background: traditionally a total of 30 Gy has been used (prior to that up to 60 Gy). recent reserach indicated that 21 Gy might do pretty much the same job, maybe even 15 Gy. 15 Gy would allow a second treatment sometimes later, if needed, without exceeding a total of 30 Gy which is considered tolerable.

b) minimize travelling of the patient to make it more convenient

The treatment regimes that you are describing are

1. the classical treatment with 5x3 Gy, 6-8 weeks break, 5x3 Gy. The break is meant to allow the skin to recover and thus minimize side effects

2. 7x3 Gy is the reduced dose, 21 Gy in total. Those 7 treatments are merged into a single week to minimize travelling.

3. 5x3 + 5x3 Gy is the classical way again but without the recovery period in between. This minmizes treatment time but might result in stronger skin reddening and dryness. It also does not allow inspection of results after 6-8 weeks and possibly postponing of the 2nd round if results are already good.

Basically all three regimes will probably work, i.e. give similar treatment effects. Side effects and travelling effort might vary.

Re: Radiation-different treatment plans

I had RT with Dr. Tripuraneni at Scripps hospital in LaJolla, CA last November. After 10 months, it seems to have stopped the progression of the disease in my hand as well as in my foot (I had RT both for my DD and Ledderhose). I had no dryness or any problems from the radiation... only positive results, no more itching and burning, decrease in size of nodules and able to open my hand much wider after RT.

Dr. T. is a knowledgeable, kind, and very professional doctor. Since you live in San Diego, and if your insurance covers it, consult with Dr. T. and ask him all your questions. I am sure that he can clearly explain what the differences are and why he thinks the method he is using is adequate. You will like him !

Bob,



2. 7x3 Gy is the reduced dose, 21 Gy in total. Those 7 treatments are merged into a single week to minimize travelling.



As far as I read the publication by Seegenschmiedt:

7 x 3 Gy within 2 WEEKS , i.e. every other day which makes it
a Monday - Wednesday - Friday Schedule which was tested
against the 5 x Gy 8 - 10 weeks break plus 5 x 3Gy schedule

So TRAVELLING is ONE TIME but hotel expenses are TWO WEEKS

May be I am wrong , but that'S my understanding of 7 x 3Gy

Re: Radiation-different treatment plans

Hi,

I had my first RT yesterday (9/10) in Santa Fe, NM which is about 30 min. away for me. Initially, he told me I would have my first treatment Friday and then come back each day the following Mon-Wed, and perhaps more. He was going to consult w. Dr. Herman in OK. So I was surprised when I was told to come back on Thursday, which would be 6 days later. While I didn't speak diretly with the doctor, the radiotherapist did double check. So I thought I would check on my own here to see what the "norm" for incidents or treatments, time inbetween, is--there is any. I thought because travel/hotel is not an issue, perhaps that is why my treatment is more spreadout. Wondering what others experiences are?

Hi Casa,
I had treatment with Dr. Hermann in Oklahoma, I went for four days in a row, seven treatments total (I was told in the beginning it would be five days in a row) Just wanted to share what happened in Oklahoma since you mentioned your guy consulted Dr. H..
Unfortunately, while I had no side effects, not even dry skin for more than a day or so, my Dup continutes to march on.

Re: Radiation-different treatment plans

I had treatment #1. 5 days in a row with 6-8 weeks separating the 2nd treatment of 5 days in a row. I had a little dry and reddened skin that lasted a few months. You could see the exact area that was treated by the red skin. My DD appears to be in total remission. No pain, more flexibility, I can fully open my hand, the nodule has all but disappeared, the cord shrunk and seems for the most part to have recessed into my palm. You can still see it if you are looking. If someone squeezes while shaking my hand I will have pain. I still have a general weakness in that hand. Dr. Crimaldi and I chose this regime because of the research provided by the Germans. I would choose this regime again if the DD returns. So far it has been over a year with no new nodules or growth. My DD was so aggressive in its growth from a sore spot to a 4 inch cord in less than 6 months, that I felt I needed to go with the research and "proven" method. I did not feel like I had the time to see if a lesser RT regime would be just as effective.

Each persons DD is different as is their choice for the treatment protocol. It is a little confusing, because unlike some diseases, we do have choices as to how to treat. I know I used to wish there was one and only one way to treat it. I think I would have slept better, rather than mentally debating what was best at all hours of the nght. I know after going through RT I am a big believer in it.

Regards,


Lori

Re: Radiation-different treatment plans

I did treatment no.3. I did 5 days of RT using 2gy and weekend off and then 5 days 2gy and it has worked for me. My doctor is about 15 minutes from where i live and i feel very lucky he is so close. It has been 6 months since my RT and i still have no activation. My right hand was worst so of course it looks different than the left hand. My left hand looks like before the disease started. The right hand had a month jump start of the disease so the sooner you get it done the better the results will be. I fully believe that if i had not of done this i would be looking for someone to do NA on my right hand. All nodules are so tiny they are smaller than a BB pellet. And as for the cords i have one that is still sticking out on the palm of my right hand and it just doesn't want to go away. The skin on my right hand always feels tight across the palm. But with what i have learned RT doesn't do a lot for your cords and if you lucky it helps a little.

No Side effects sounds a little bit strange ... could be that you had not sufficient dose !?
This would explain your progress despite radiation ?

Re: Radiation-different treatment plans

Yes, Larry, I agree it is very strange.
But don't have any way to confirm or disprove proper treatment.
Just know for sure I was very disappointed.
