Do people put a small y in front of their AJCC TNM stage if there is reported preoperative chemoradio?? For example, patient arrives with 8cm mass, chemoradio follows, mass is resected but is only 2 cm at time of resection when it reaches path. That difference in size bumps the pT from say a pT2 to a pT1 so you designate the chemoradio by saying ypT1 pN0 MX. I have never heard of this before and I thought I was omnipotent.... Also, in cases of preop chemoradio where there are nodes with just mucus but no carcinoma, do you mention "pericolic lymph node with metastatic mucus, no evidence of residual carcinoma"? Damn radoncs, making our lives hard, yet again!
