Most often, positive margins, i.e. surgical margins with disease present, suck. For example, in locally advanced [[rectal cancer]], in one study,<ref name=pmid17614249>{{cite journal |author=Larsen SG, Wiig JN, Dueland S, Giercksky KE |title=Prognostic factors after preoperative irradiation and surgery for locally advanced rectal cancer |journal=Eur J Surg Oncol |volume=34 |issue=4 |pages=410–7 |year=2008 |month=April |pmid=17614249 |doi=10.1016/j.ejso.2007.05.012 |url=}}</ref> five year survival was found to be 60%, 31% and 0% for R0 (no tumour at the margin), R1 (microscopic tumour at the margin), and R2 (macroscopic tumour at the margin) resections respectively. | |||
