Are there select patients with rectal cancer where radiation field size reduction might be feasible?  

Yes, however, how to select which patients could have a field size reduction is unknown. Such a field size reduction is probably even more acceptable in the era of total neoadjuvant therapy, however, this cannot be considered standard of care given the absence of trials evaluating such novel approac...

I think the most important way to limit the elective nodal volume is to limit its cephalad extent, since that makes it easier to reduce the volume of irradiated alimentary canal. With regard to that, the RAPIDO trial specifically limits the elective nodal CTV to below the S1-S2 level for coverage of...

I agree that field reduction is only done in clinical trials and is not the standard of care.
