Hi,
I had 6-1/2 weeks of radiation treatment with weekly concurrent chemo with Cisplatin and Erbitux.
Yes, the side effects will build up over time - and feeling good after the first week means nothing with regard to what is to come. Everyone takes the treatment differently, but here are some of the issues I had to deal as treatment progressed:
1. Nausea: I also had daily Ethyol shots, which really seemed to make me more nauseous than the chemo. I took Zofran 3 times per day, and it worked well (not forgetting that anti-nausea drugs are also provided with the chemo).
2. Loss of taste: This is more difficult than it sounds as food actually tastes horrible. I settled on a meal (which I ate 3 times per day) of egg-beaters with cheese (and sometimes ham), 2 Boost Plus, and tea with honey - about 2700 calories per day. Eating and drinking water are critical - a lot of people lose a lot of weight (many get a PEG prior to treatment, or during treatment if they cannot keep up their weight - I did not get a PEG and lost only a few pounds).
4. Very sore throat: This was a big problem which also made eating difficult. I got a mouthwash concoction from my dentist (who specialized in radiation treatment patients) which I took before each meal to numb my mouth and throat to help me eat. I also took a Tylenol-codeine mixture which helped quite a bit.
3. Thrush: I got this twice, and was readily treated.
4. Canker sores: I got a little bit of this and used a topical treatment.
5. Thickening of saliva: I didn't get this too bad, but some do.
6. Constipation: At the end of treatment this was a big problem.
7. General lack of energy: the treatment just kind of wore me out over time.
8. Radiation burns on outside of neck: These showed up late in treatment and really blossomed after treatment was over (if I recall, it was thought the Erbitux contributed to the severity of the burns).
9. Pimples: The Erbitux caused a huge outbreak of pimples on my chest, upper back, and worst of all on my face (even inside my nose). Steroids and antibiotics took care of them.
It wasn't until about 3 weeks or so post treatment that I started climbing out of the impacts of treatment. It was a slow road after that, but within a couple of months I was doing pretty well. I also kept exercising during treatment, including almost daily walks (nothing too strenuous, though, due to concerns about burning too many calories), which I think helped not only physically but emotionally.
It is key to tell the doctor or nurse about each side effect that occurs and to understand that the first remedy prescribed my not work well (we're all different) - if something doesn't work, try something else until you get the best result.
Anyway, I think that's the highlights. The treatment is tough, but doable.
Best wishes,
Chris
