We have received biopsy report for a kidney tumor that has been graded pT3a. They have tested 2 lymph nodes and they were negative for cancer. Our initial diagnosis before the biopsy was that it had metastasised into the lungs however the report says that pM 'Not applicable, pM cannot be determined by samples received' and the doctor has said there's no evidence that it has spread to other organs.
My question is does this report mean that it hasn't metastasised into the lungs? Or just that the tumor and lymph nodes were tested and the lungs nodes weren't?
Just trying to understand whether the grading of the tumor is just for the tumor itself or whether it's the stage of the patient too.
Thanks.
