Patients with stage IIIB and IIIC colon cancer represent a heterogeneous group of patients with the majority either overstaged or understaged. LNR is a more accurate prognostic method for stage III colon cancer patients. We propose an algorithm to incorporate LNR into current AJCC staging system.
Colon cancer patients with LNR4 disease represent a heterogeneous group. The previously reported prognostic association of TNODS and LNR and outcome of stage III disease were confounded by LODDS.
Most neurologic events after heart surgery occur in a subset of patients who can be defined before operation. Whereas carotid artery stenosis greater than 50% is a strong risk factor, the role of prophylactic endarterectomy is unclear. Future studies should focus on this high-risk subgroup. A prospective study of prophylactic carotid endarterectomy in patients undergoing coronary artery bypass grafting is needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
