I just finished 15 radiation treatments to my lung tumor 1 week ago . I've also been on Tagrisso for the past 8 months and I did continued taking it throughout radiation treatment.
I have pretty bad esophagitis now which I was aware off might happen. I also started to run a low grade temp ( 100.7 rect. ) that happens in the late afternoons and goes down in the am. I'm not taking any fever reducers or pain meds right now. ( BP low 95/56 )
I'm also experiencing shortness of breath, increased dry cough and a flue-ish malaise causing me to spend most of my day resting and/or in bed.
I have low level autoimmune disease and my immune system is chronically upregulated anyway.
As far as I can tell the symptoms I'm experiencing might suggest radiation induced pneumonitis.
My question is:
How do you monitor someone who is at increased risk of pneumonitis like me?
Apart from imaging, can you make an educated guess by doing lab work ( white blood count, sed rate ...) ?
If pneumonitis is found can it be treated with inhaled corticosteroids if it's at a low level ?
Would I have to stop Tagrisso therapy which would endanger stability of the brain ?
I made an appointment for today and will ask the doc for more stringent monitoring in my case.
I'm trying to be vigilant , keep damage to a minimum and avoid fibrosis.
Thanks for any advice
