My dad completed 6 rounds of cisplatin/etoposide, PCI, and 33 radiation treatments to his right lung for limited small cell lung cancer almost 3 months ago.
He was supposed to have his first 3 month CT scan on 08/20/2012 and the medical oncologist followup 08/27/2012 but developed shortness of breath and coughing around 08/01/2012. His radiation oncologist suspected radiation pneumonitis and had a CT scan done the next day.
The radiation oncologist reviewed the CT scan today and said everything had resolved (no evidence of disease) except a small soft tissue mass had appeared in the radiation field.
He said it could be scarring, pneumonitis, or a tumor and has ordered a PET scan for next week.
I was just wondering if scarring or pneumonitis manifests itself as a small soft tissue mass or are we dealing with a recurrence?
We had a CT scan done at the end of 05/2012 and this mass was not present but the original tumor which has now disappeared was.
The signs are all there for pneumonitis but the small tissue mass has everyone scared, any help is appreciated.
