Sorry if this is the wrong place for this...
My father had a pneumonectomy on Friday and is doing very well in his recovery and is on his way home now. The preliminary path report came back yesterday and the doctor told my mother that it is "2a-2b" and that he did not expect the final report to differ. This is based on the tumor being 5-7cm and them finding cancer in (I think) one secondary lymph node in the lung they removed. We were told that it has not metastisized to any organs. Before the surgery he had another lymph node outside the lung biopsied which was negative and there is no indication that t is in any other lymph nodes.
Here is what I don't understand and I am hoping someone can help me with. Since from what I have been able to gather from reading online it seems like pneumonectomies are not exactly common so I am not sure how a lot of what I just described means to his specific case. I know the size of the tumor is relevent but is it less relevant since they removed the entire lung? From what I have read it seems obvious that it is stage 2b. I am not sure why the doctor couldn't tell them that and I am not sure what that means in regards to his overall prognosis. Does the fact that they removed the lymph node that had the cancer and none of the other lymph nodes have shown signs of being cancerous improve his prognosis? Or once it is in the lymphatic system it doesn't matter and it is treated the same way? Does that mean that this is really no better than stage 3 and the pneumonectomy was done in vain?
I know these are questions for the doctor but he is just getting out of the hospital and I am not sure when his next appointment is or with who so I was hoping someone could help. Thanks in advance.
