PURPOSE We determined the prognostic value of carcinoembryonic antigen (CEA) clearance after tumor resection with serial evaluation of postoperative CEA levels in rectal cancer. METHODS Between 1994 and 2004, we retrospectively reviewed 122 patients with rectal cancer whose serum CEA levels were measured on the preoperative day and postoperative days 7(More)
PURPOSE Circumferential resection margin (CRM) involvement is a well-known predictor for poor prognosis in rectal cancer. However, the significance is controversial in some studies. Accordingly, this study attempted to examine the prognostic impact of CRM involvement in stage III rectal cancer. MATERIALS AND METHODS Between January 1990 and December 2007,(More)
BACKGROUND We investigated the prognostic significance of tumor regression grade (TRG) after preoperative chemoradiation therapy (preop-CRT) for locally advanced rectal cancer especially in the patients without lymph node metastasis. METHODS One-hundred seventy-eight patients who had cT3/4 tumors were given 5,040 cGy preoperative radiation with(More)
Robotic techniques have been developed to facilitate endoscopic surgery and to overcome its disadvantages. Thus, we performed robotic total mesorectal excison (TME) in a patient with rectal cancer, using the da Vinci(®) Surgical System. To our knowledge, this is the first robotic low anterior resection, based on standard TME principles, with pelvic(More)
PURPOSE Transplant recipients in Asia appear to be at a higher risk for developing colorectal cancer (CRC). This study was performed to identify the clinicopathological features and oncologic outcomes of CRC in post-renal transplants in Korea. MATERIALS AND METHODS We retrospectively reviewed the records of 17 patients with CRC out of 2,630 recipients who(More)
the cessation of capecitabine a ects the recurrence rate, but dose reduction does not. is study presents a clinical guideline that chemotherapy using capecitabine should be continued even when the dose must be reduced because of complications. As indicated above, this study will become more meaningful if the dependences of the prognostic factors related to(More)
