Would you offer postoperative RT for pT2pN0 rectal cancer with close distal margin (within 2 mm) and only 6 lymph nodes obtained from surgery?   

I assume the question is about the addition of chemoradiation in this setting. In this case, there is one clear reason to consider post op chemoradiation - the 6 LNs removed. This is clearly short of the standard for adequate lymphadenectomy of 12. It may be possible to ask the pathologist to review...
