Clinical implication of tissue carcinoembryonic antigen expression in association with serum carcinoembryonic antigen in colorectal cancer.

This study aimed to evaluate the prognostic significance of carcinoembryonic antigen (CEA) expression in tumor tissues of patients with colorectal cancer (CRC). The cohort included 7,412 patients with CRC from January 2010 to December 2015. Survival outcomes were assessed based on tissue CEA (t-CEA) patterns and intensities.

Entirely Robot-assisted Total Colectomy/Total Proctocolectomy Compared With a Laparoscopic Approach.

Purpose: Previous robot-assisted total colectomy/total proctocolectomy (TC/TPC) has been mostly confined to completion proctectomy combined with open or laparoscopic colon dissection. This study describes an integrative method of entirely robot-assisted maintaining anatomical dissection with single docking and one-off arm placement.

Materials And Methods: Twenty patients who underwent robot-assisted TC/TPC and 36 who underwent laparoscopic procedures at the Asan Medical Center (Seoul, Korea) were enrolled.
