DIB, Memorial Sloan Kettering does use Pa, P0, P1, etc. then notes that they follow the 1997 UICC clinical staging system. I googled that and came up with the same TNM - tumor, node, metastisis, ie. Ta, T0, T1 etc. So to make things simpler, I would go wih the 99.9% world wide usage and substitute T for P.
If anyone is a current patient at MSK, please ask them why they use the letter P for staging instead of T, and does it really correspond to the 1997 UICC clinical staging system?
Pat, I couldn't get my mind around your last link. All I figured out was that is was OK to put a lowercase p in front of the uppercase T for staging.
Yep thats what i thought.......sorry about that...sometimes my multitasking gets mixed up........heres the link
Not that this makes it any clearer!!!
That link just went to Dr. Josephson's page. However, I'm guessing from what you said in that last e-mail, that the "P" prefix might be used when reporting the stage findings from a post-cystectomy pathology exam? And would "T" be used for staging that is done through cystoscopy and TURBT pathology results?
Small TA Grade 1, May-06; recur (2 tiny), same, June-08; TURBTs both times. BCG begun July-08, dosage to 1/3rd May-10, completed treatment December-11. All clear since 2008.
Another set of letters confuse us......maybe this will help......it has to do with pathological findings after cystectomy
