Good evening Dr. West:
My husband has completed three cycles of his chemo doublet and had his first CT Scan since the assessment phase in Dec 2013. The oncologist told us that the cancer is stable.
While being assessed, the PET scan showed two possible mets to the brain and the hip. MRI were done on both. The results of the hip MRI came back suspicious for cancer. We were told it was worded this way as one cannot conclusively say cancer without a biospy. (The brain mets have been treated with open brain surgery and Cyberknife.)
His diagnosis was:Stage IV NSCLC Adenocarcinoma with focal sarcomatoid differentiation, T2a , N0, M1 to brain and right acetabulum.
The latest CT scan shows absolutely nothing on his hip. How can this be? It is my understanding that if it is a result of the chemo then there should be some calcification on the bone. Could his initial diagnosis be wrong? The nodes were all clear. Is this normal in metastatic disease?
