== Chemotherapy regimen update == 

 Today (as of 2014) adjuvant 5-fluorouracil chemotherapy, with oxaliplatin, is given before surgery (sometimes afterwards as well) for stage 3 colon or rectal cancer.  I have updated the appropriate section, with a reference to an NCI web entry. 

 Also, please note that a colon or rectal tumor is called stage 3 if it has penetrated the wall of the colon or rectum and is growing on both sides of the wall, even if no lymph nodes are involved.
