Initial experience of robot-assisted radical cystectomy with total intracorporeal urinary diversion: comparison with extracorporeal method.

Purpose: To report our surgical technique and initial experience with robot-assisted laparoscopic radical cystectomy (RARC) with total intracorporeal urinary diversion compared with an extracorporeal method.

Subjects And Methods: In total, 42 patients underwent RARC by a single surgeon at our institute for clinically localized bladder cancer. Among these, 4 patients underwent RARC with complete intracorporeal urinary diversion.

Relationship between meat and cereal consumption and colorectal cancer in Korea and Japan.

Background And Aim: The incidence of colorectal cancer in Asian countries is increasing. The change to a more westernized diet is known to be related to these increases, and there are reports on the relationship between meat consumption and colorectal cancer in Japan. The aim of this study was to investigate the relationship between dietary change and colorectal cancer in Korea and Japan.

The prognostic significance of E-cadherin and liver intestine-cadherin expression in colorectal cancer.

Purpose: The significance of liver intestine-cadherin as a potential marker has been growing in the field of oncology, because of its unique features compared with classic cadherins. We investigated the coexpression patterns of E-cadherin and liver intestine-cadherin in colorectal cancer, and determined whether differences in expression patterns were associated with clinicopathologic parameters and also which relationship between these two adhesion molecules existed in colorectal cancer.

Methods: Expression pattern of E-cadherin and liver intestine-cadherin was investigated immunohistochemically in 207 colorectal cancers along with clinicopathologic parameters.

Simultaneous laparoscopic radical nephrectomy and laparoscopic sigmoidectomy for synchronous renal cell carcinoma and colonic adenocarcinoma.

Hand-assisted laparoscopic radical nephrectomy is an established therapeutic choice for localized renal cell carcinoma. Laparoscopic sigmoidectomy is becoming accepted for the treatment of locally advanced sigmoid colon cancer. Primary cancer may occur synchronously in two different organs, in which case simultaneous resection is recommended if possible.
