Preoperative Carbohydrate Antigen 19-9 Levels Can Predict Stage and Survival Rate in Patients with Colorectal Cancer: Soo Young Moon, Jae Myung Cha, Joung Il Lee, Kwang Ro Joo, Hyun Phil Shin, Jae Jun Park, Jung Won Jeon, Jun Uk Lim, Seung Jung Jun, Yoon Jong Seo, Chi Hoon Lee; Intest Res 2013;11(3):184-190. Published online July 30, 2013; DOI: https://doi.org/10.5217/ir.2013.11.3.184

Background/Aims
The purpose of this study was to determine whether preoperative carbohydrate antigen 19-9 (CA 19-9) levels can predict the stage of diseases or survival rate in patients with resectable colorectal cancer (CRC). Methods: A total of 247 patients who underwent curative resections at Kyung Hee University Hospital at Gangdong between 2006 and 2011 were enrolled. We investigated the correlations of preoperative serum levels of CA19-9 with clinicopathological features of CRC. Receiver operative curve was constructed for evaluating the efficiency of the serum CA 19-9 levels in the stratifying stage of CRC. Survival analysis was performed with Kaplan-Meire method and log-rank test. Cox regression analysis was used for the multivariate analysis for survival. Results: Abnormal level of serum CA 19-9 (>37 IU/mL) were associated with advanced T stage (P<0.001), N stage (P=0.002) and TNM stage (P<0.001) in patients with resectable CRC. Furthermore, abnormal level of serum CA 19-9 were related with vascular invasion (P=0.002) and lymphatic invasion (P=0.026). The area under the curve was 0.75 (95% confidence interval [CI] 0.67-0.83) for T4 stage CRC and 0.680 (95% CI 0.61-0.75) for TNM stage III CRC. In patients with TNM stage III CRC, a preoperative CA 19-9 higher than 60 IU/mL (P=0.033) and presence of vascular invasion (P=0.002) were identified as significant predictors of survival rate on multivariate analysis. Conclusions: In patients with resectable CRC, preoperative CA 19-9 correlates with T stage, N stage and TNM stage of disease. Serum CA 19-9 >60 U/mL was an independent predictor of survival rate in the patients with TNM stage III CRC. (Intest Res 2013;11:184-190)

Clinical Characteristics and Outcomes of Diverticulitis by Physician's Specialty: Seung Jung Jun, Jae Myung Cha, Joung Il Lee, Kwang Ro Joo, Hyun Phil Shin, Jae Jun Park, Jung Won Jeon, Jun Uk Lim, Yoon Jong Seo, Soo Young Moon, Chi Hoon Lee; Intest Res 2013;11(2):92-99. Published online April 30, 2013; DOI: https://doi.org/10.5217/ir.2013.11.2.92

Abstract PDF: Background/Aims
Several factors affecting the severity and outcomes of diverticulitis have been reported, but there is little research on physician specialty related with this disease. Therefore, we evaluated the clinical characteristics and outcomes of diverticulitis depending on physician's specialty. Methods: Medical records of 239 patients, who had been hospitalized with first-diagnosed acute colonic diverticulitis at Kyung Hee University Hospital in Gang Dong (Seoul, Korea) from June 2006 to December 2012, were retrospectively analyzed. The patients were classified according to whether they had been managed by gastroenterologists or not. Clinical characteristics and treatment outcomes were compared between two groups. Results: Of these 239 patients, 38 (15.9%) patients were treated by a gastroenterologist and 201 (84.1%) patients by a non-gastroenterologist. Clinical characteristics such as age, gender, body mass index, comorbidity, medication, laboratory results, recurrence and complication were not significantly different between two groups. However, right-sided diverticulitis predominated in the non-gastroenterologist group (79% vs. 91%, P=0.028). From the sub-group analysis of uncomplicated diverticulitis, intravenous antibiotics was used for a shorter period of time by gastroenterologists than non-gastroenterologists (3.3±1.9 days vs. 4.4±2.8 days, P=0.032). Multivariate logistic regression analysis showed that the 3 day administration of intravenous antibiotics significantly depended on the physician's specialty (odds ratio 7.984, 95% confidence interval 1.990-32.043, P=0.003). Conclusions: The results suggest that the duration of intravenous antibiotics for treating uncomplicated colonic diverticulitis was shortened by gastroenterology specialists without increasing operation or recurrence.

The Improvement of Nutritional Support with Percutaneous Endoscopic Gastrostomy: Yoon Jong Seo, Jae Myung Cha, Joung Il Lee, Kwang Ro Joo, Hyun Phil Shin, Jae Jun Park, Jung Won Jeon, Jun Uk Lim, Seung Jung Jun, Soo Young Moon, Soo Young Moon, Mi Ran Cho, Jung Sook Lee; Intest Res 2013;11(2):120-126. Published online April 30, 2013; DOI: https://doi.org/10.5217/ir.2013.11.2.120

Abstract PDF

Background/Aims
Percutaneous endoscopic gastrostomy (PEG) is the most common method of enteral nutrition for patients who require long term artificial nutrition. PEG has been used as a method of nutritional support; however, improvement of nutritional support via PEG has not yet been reported. In this study, we analyzed the efficacy of nutritional support via PEG. Methods: We conducted a retrospective analysis of 196 consecutive patients who underwent PEG at Kyung Hee University Hospital in Gang Dong from 2006 to 2012. We analyzed clinical characteristics, the method of nutritional support, and the proportion of intake to establish recommendations for nutritional requirements and the duration needed to reach the level of appropriate nutrition. Results: A total of 196 patients included 130 men and 66 women, and their mean age (standard deviation) was 69.1±14.0 years. Compared with caloric and protein supplementation before PEG, 113 kcal (13.8% of baseline) and 4.8 g of protein (17.5% of baseline) could be additionally supplied with PEG (P=0.001, respectively). The number of patients who could take more than 90% of the recommended requirements of caloric and protein supplementation after PEG showed increased caloric and protein intake by 25.4% and 20.2%, respectively, in comparison with those before PEG (P=0.001 and P=0.001, respectively). The mean duration of catch-up for more than 90% of the recommended caloric and protein intake was approximately 11 days. Procedure related complications and early mortality were reported in 8.1% and 0% of patients, respectively. Conclusions: PEG is an effective and safe nutritional support method for patients who require long term artificial nutrition. (Intest Res 2013;11:120-126)

Clinicopathological Characteristics of Colorectal Cancer according to Gender Difference: Dae Ho Kim, Jae Myung Cha, Joung Il Lee, Kwang Ro Joo, Hyun Phil Shin, Jae Jun Park, Jung Won Jeon, Jun Uk Lim, Seung Jung Jun, Yoon Jong Seo; Intest Res 2012;10(4):365-371.

Abstract PDF

Background/Aims
Colorectal cancer (CRC) has been one of the major causes of death and has become a major public health concern. The incidence of CRC has been increasing regardless of gender in Korea. Until now, however, the studies on gender-based clinicopathological characteristics of CRC focused on pathology have never been reported. Therefore, we aimed to evaluate the difference in clinicopathological characteristics of CRC according to gender in Korea. Methods: Medical records of 342 patients with advanced CRC who underwent surgical resection at Kyung Hee University Hospital at Gangdong from June 2006 to December 2011 were retrospectively analyzed. The data of the clinicopathological characteristics of CRC by gender difference were compared. Results: Of these 341 patients, 203 (60%) patients were male and 138 (40%) patients were female. The male preponderance was noted in all age groups for total CRC and left-sided CRC. However, for right-sided colon cancer, this male preponderance was significantly decreased with increasing age groups (P=0.025) and was finally reversed in elderly groups (age ≥60 years). The microsatellite instability represented by negative staining for hMLH1 and hMSH2 was more frequently detected in women than men (P=0.037). Conclusions: The male preponderance in right-sided colon cancer decreased with increasing age groups and finally reversed in age groups more than 60 years. Microsatellite instability with immunohistochemical staining was more frequently detected in women. However, further studies with a large number of patients are warranted on this issue.
