Background & Aims: Hepatobiliary magnetic resonance imaging (MRI) provides additional information beyond the size and number of tumours, and may have prognostic implications. We examined whether pretransplant radiological features on MRI could be used to stratify the risk of tumour recurrence after liver transplantation (LT) for hepatocellular carcinoma (HCC).
Methods: A total of 100 patients who had received a liver transplant and who had undergone preoperative gadoxetic acid-enhanced MRI, including the hepatobiliary phase (HBP), were reviewed for tumour size, number, and morphological type (e.
Background/aims: Endoscopic submucosal dissection (ESD), a new and potentially curative method for treating gastrointestinal neoplasms, may have longer procedure time and the risk of complications when compared to conventional endoscopic mucosal resection. This study evaluated the efficacy and safety of ESD in patients with comorbid diseases.
Methods: The outcomes of 337 patients who underwent ESD for early gastric cancer at Samsung Medical Center from April 2003 to December 2006 were analyzed retrospectively.
Objective: The superficial spreading type of early gastric cancer (EGC) possesses unique features different from other types of EGC. We aimed to elucidate the clinicopathological features of superficial spreading type of EGC.
Material And Methods: We analyzed 1455 EGC lesions from 1398 patients who had undergone surgical treatment at Samsung Medical Center from 2000 to 2002.
Purpose: To compare treatment results between the use of two different radiation fields including and excluding remnant stomach and suggest new target volumes excluding remnant stomach after subtotal gastrectomy (STG) in patients with stomach cancer.
Methods And Materials: We retrospectively analyzed 291 patients treated with adjuvant chemoradiotherapy after STG and D2 dissection at the Samsung Medical Center, Seoul, South Korea. Eighty-three patients registered from 1995 to 1997 underwent irradiation according to the INT 0116 protocol that recommended the inclusion of remnant stomach within the target volume (Group A).
An observational study suggesting clinical benefit for adjuvant postoperative chemoradiation in a population of over 500 cases after gastric resection with D2 nodal dissection for adenocarcinoma of the stomach.

Purpose: The role of adjuvant chemoradiotherapy (CRT) in D2-resected gastric-cancer patients has not been defined yet. We investigated the effect of postoperative chemoradiotherapy on the relapse rate and survival rate of patients with D2-resected gastric cancer.
Methods And Materials: From August 1995 to April 2001, 544 patients received postoperative CRT after curative D2 resection.
