My wife is 49 and has an adenocarcinoma in her right lung apex of about 6 cm in each dimension. This has been confirmed with needle biopsy. This was followed by a PET scan and a brain MRI. Both of these showed clean (except for the right lung on the PET with a SUV of ~14). The issue is that the left lung CT showed a speculated mass about 1 cm. x 1.7 cm. in the left lung apex. Even though the PET was negative, a needle biopsy was done and confirmed an adenocarcinoma. We meet with the onco next week but was wondering if you could help in the meantime with the following questions:
1. Statistically, is this likely a primary or secondary tumor?
2. If it is secondary, does that automatically make it a Stage 4?
3. If everything other than the lungs are truly clean, is surgery still an option?
4. How did this likely spread from one lung to the other (lymph nodes showing clear, no other signs of mets).
5. Is it common to spread to the other lung and not other areas of the body?
6. What is the likely prognosis for this situation?
I really appreciate any information. I am sure we will learn more next week, but the waiting has been so difficult as I am sure many of you can relate to.
Thank you and bless you.
