My mother had 21 sessions of Rapid Arc radiation for her lungs. She had lesion ih her right lung upper lobe and metastasis on two lymph nodes (paratracheal and right hilar ones).
Before that, she received 4 cycles of Cisplatin/Gemzar without any response.
Radiation treatment finished three months ago and we just had first PET CT. First words by our oncologist were that she thinks it is a good response but that there is possibility of residual and new metastase near the treated lymph node.
She decided not to do anything for now, but to wait for another three months when all inflammation should disappear and we will see what will be left.
After I read PET CT report I was really scared as Nuclear Medicine Physician wrote the following:
"FDG uptake of lesion at right lung upper lobe has significantly decreased (ˇ-75%), but a focal FDG uptake suspicious for residual is still discernible.
A focal increased FDG uptake at right hilus is seen without a corresponding lymph node, suspicious for lymph node metastasis, right hilar FDG uptake was not at this exact location in previous study."
I am really scared about the possibility that something new, untreated at all, can appear in these three months, and how big these residual and metastase can grow?
I would really like to hear some opinions and experiences...
