Pre-Treatment Planning

We were told that it is better to not know where the primary tumor is, because that would mean that the primary tumor hasn't grown enough to be real resistant to radiation - thereby giving the radiation a better chance of killing the primary site cells. However, I must admit that I felt better knowing that the primary site was found. And removed. And to be followed up with the radiation to kill any errant cells that may be still present.

Prior to beginning my radiation treatments, I arranged to have a dental checkup. This is strongly recommended in radiation treatments to the oral cavity. The radiation is very hard on your teeth and gums. There is a pretty nasty word called xerostomia that sums up what happens when you get radiation to your mouth area. (Here is more recent info, covering xerostomia and use of Ethyol). After reading about it, I felt compelled to do everything I can to try and preserve my teeth, and practice good oral hygiene! I had panorama x-rays done. Cleaning. Two teeth had cracked fillings - got those taken care of. It seems that radiation treatments accelerate tooth decay, so even the smallest crack or cavity could end up being real problematic down the road. I'd recommend giving this some attention early, to prevent problems. I also got a prescription for some special fluoride toothpaste called Prevident 5000 Plus (Colgate).


Side Effects

I'll provide my radiation experience in an outline form to give an idea of how things went from week to week. Before I get into that though, I should mention that radiation treatments do have side effects. Believe me! I documented how I felt as the weeks rolled by, but everyone experiences it differently. There are certain things that will definitely happen, however. Some of these include:


Before starting my treatments Dr. Gleich, Dr. Redmond and I agreed that we would meet somewhere around the 5th week to reassess the efficacy of the radiation treatments. This would be necessary in order to determine whether or not further surgery (i.e., neck dissection) would be necessary. The hope is that the radiation will do the trick, and shrink the tumor away to nothing.

My original radiation treatment was to consist of 5-6 weeks of radiation. Since I was not getting the radical neck dissection prior to radiation treatment, the course of treatment was increased to 7 weeks. I wanted to know about the equipment, what type of radiation, what the actual dosage would be . . . and on and on. I was full of questions, to the point that I'm sure they hated seeing me coming with my little steno pad and pen!


Simulation

Before the actual treatments could begin, I had to undergo what is called a simulation. The simulator is a diagnostic tool that has a fluorscope attached that allows better imaging for setting the targets for the linear accelerator used in the actual treatments. I'll get into that in a minute. But before the simulation could be done, I had to be fitted with a mask. This was an interesting procedure, with a good idea behind it. They lay you down on a bench and create a plaster mold of your head (this is probably bad if you're claustrophobic). Your head is covered with the warm plaster, leaving only nose holes and a mouth hole (~ 2" dia.). You get to breath out of a plastic tube. This tube goes with you until the final treatment, and you may be able to save the tip of your tongue by extending it (your tongue) as far into the tube as possible during the irradiation.

Once the plaster mold is made, a clear plastic mask replica of your head is created from the mold. This mask is what will be used to bolt your head into place so you cannot move it during the "rad treats." The mask is also what allows the alignment marks to NOT be made on your skin (although you will still probably have to have a few marks drawn on you for field alignment purposes). The majority of marks are made on the mask, which helps to keep everything consistent and keeps you from looking like a jigsaw puzzle.

The simulation is the process of getting the alignments made, and marks made so that when you get the real treatments, they will be to the exact same spots - every time! You lay down and are bolted in with your mask. X-rays are taken to assess the exact position necessary for the x-ray blocks to be located. The "blocks" are molded pieces of metal alloy, that will prevent radiation from affecting areas not needing treatment. Also, the fields that will be radiated are defined. In my case, I was to get a dose of 90 cGy (centigrays, or RADS) to both the left and right upper neck and cheek areas (for a total dose of 180 cGy/day). And a lower field of 180 cGy/day to the front clavicle and lower neck area. I had a block on the lower field that left me with a (temporary) white stripe up the center of my throat (this protected my spine and esophogus). The blocks I had on the left and right sides created a definite curved line (from the radiation burning) on my skin, that came forward from the middle of my ear to my cheekbone, and curved down to my jaw. This will all make more sense if you view the photos on the photos page.

The simulation lasted about 45 minutes. And that is a long time to be in that mask, believe me!! The normal treatments only take a few minutes. Physically, this was the most uncomfortable part of getting the treatments (notice I didn't say anything about the side effects of the treatments!).

Once everything has been aligned, blocks made, and everyone is happy, you can start with the real thing . . .

Most people won't go more than 7040 cGy. I think that this is a limit for treatment. I'll tell you one thing, 38 treatments is more than enough to last me!

I get emails from readers of these SCC cancer pages almost every day. I am surprised at the response. And I am saddened - because it means that there are that many people out there looking for this information. And that means that there are that many people that are being diagnosed! It's scary. I want to reiterate - attitude, educate yourself, fight it - it can be done!

Check back, and wish me luck. And the best to you and yours . . .
