Hi,
I think Disease Extent can be derived from TNM but I just wanted to check that.
Is this a correct algorithm to derive Disease Extent?:
- If M = 0 and N = 0 then Disease Extent = Confined Disease
- If M = 0 and N > 0 then Disease Extent = Invasive Disease
- If M = 1 then Disease Extent = Metastatic Disease
What should be done with NX and MX?
Alternatively, can the disease extent also be derived from the staging groups?:
- If Stage = I then Disease Extent = Confined Disease
- If Stage = II, III then Disease Extent = Invasive Disease
- If Stage = IV then Disease Extent = Metastatic Disease
Thanks for your help,
Peter
