Risk of recurrence after endoscopic resection of early colorectal cancer with positive margins.

Background And Study Aim: Additional surgery is recommended if an endoscopically resected T1 colorectal cancer (CRC) specimen shows a positive resection margin. We aimed to investigate the significance of a positive resection margin in endoscopically resected T1 CRC.

Patients And Methods: We enrolled 265 patients with T1 CRC who underwent endoscopic resection between January 2001 and December 2016.

Differences in the survival rates of older patients with colorectal cancers in 2003 and 2009.

Purpose: The aim of this study was to investigate survival in patients aged ≥70 years who underwent colorectal cancer surgery in 2003 and 2009. In addition, we aimed to identify the factors that could affect survival in these patients.

Methods: In a cross-sectional study, a retrospective review of the data for 878 patients who underwent colorectal cancer surgery with curative intent in the years 2003 and 2009 was performed.

Oncologic outcomes of early adjuvant chemotherapy initiation in patients with stage III colon cancer.

Purpose: Although adjuvant chemotherapy reduces the risk of disease recurrence in stage III colon cancer patients, published guidelines do not specify when it should be initiated. This study aimed to assess the effect of adjuvant chemotherapy initiation time on disease recurrence and survival in stage III colon cancer patients undergoing curative surgical resection.

Methods: The medical records of stage III colon cancer patients undergoing curative resection between February 2004 and December 2009 were reviewed.

Exposure to music and noise during pregnancy influences neurogenesis and thickness in motor and somatosensory cortex of rat pups.

Purpose: Prenatal environmental conditions affect the development of the fetus. In the present study, we investigated the effects of exposure to music and noise during pregnancy on neurogenesis and thickness in the motor and somatosensory cortex of rat pups.

Methods: The pregnant rats in the music-applied group were exposed to 65 dB of comfortable music for 1 hour, once per day, from the 15th day of pregnancy until delivery.

The impact of old age on surgical outcomes after pancreaticoduodenectomy for distal bile duct cancer.

Backgrounds/aims: To compare surgical results and survival of two groups of patients, age ≥70 vs. age <70, who underwent pancreaticoduodenectomy and to identify the safety of this procedure for elderly patients for the treatment of distal common bile duct (CBD) cancer.

Methods: Between January 2003 and December 2009, 55 patients who underwent pancreaticoduodenectomy for the treatment of distal CBD cancer at Keimyung University Dong San Medical Center were enrolled in our study.
