The colorectal cancer (CRC) patients with microsatellite instability (MSI) have distinct clinicopathological characteristics consisting of factors predicting positive and negative outcomes, such as a high lymph node harvest and poor differentiation. In this study, we measured the value of MSI as a prognostic factor after controlling for these discrepant factors. A total of 603 patients who underwent curative surgery for stages I to III colorectal cancer were enrolled. The patients were divided i

Romo1 overexpression in tumor tissue was significantly associated with survival in curatively resected colorectal cancer patients, suggesting Romo1 expression as a potential adverse prognostic marker. Increased Romo1 expression was found to be associated with high lymph node ratio. Cancer invasiveness appeared to be a key reason for the poor survival related to highly expressed Romo1.

Inflammatory myofibroblastic tumor (IMT) of the stomach in adults is extremely rare, with unpredictable prognosis. We present a 55-year-old woman with a gastric IMT. She experienced sudden abdominal pain 4 d previously. Physical examination showed mild abdominal tenderness in the hypogastrium, but no palpable abnormal abdominal mass. Abdominal CT showed a mass of approximately 8 cm in the gastrocolic ligament. On laparoscopic exploration, unexpected hemoperitoneum of approximately 1.5 L of blood

Expression of protein kinase C-delta (PKCdelta) is up-regulated by apoptosis-inducing stimuli. However, very little is known about the signaling pathways that control PKCdelta gene transcription. In the present study, we demonstrate that JNK stimulates PKCdelta gene expression via c-Jun and ATF2 in response to the anticancer agent doxorubicin (DXR) in mouse lymphocytic leukemia L1210 cells. Luciferase reporter assays showed that DXR-induced activation of the PKCdelta promoter was enhanced by ect

Primary mucinous cystic cystadenomas of the retroperitoneum are very rarely encountered, and there have been only about 30 cases reported in the literature. The histogenesis of primary mucinous cystadenomas is unclear. Most authors suggested that it develops through mucinous metaplasia in a pre-existing mesothelium-lined cyst. Complete surgical excision is the only treatment and it is required for the final diagnosis and cure. We present here a case report of a 38-year-old Korean woman with prim

Abstract Background An underweight individual is defined as one whose Body Mass Index (BMI) is < 18.5 kg/m 2 . Currently, the prognosis in patients with colorectal cancer (CRC) who are also underweight is unclear. Methods Information on South Korean patients who underwent curative resection for CRC without distant metastasis was collected from health insurance registry data between January 2014 and December 2016. We compared the overall survival (OS) of underweight and non-underweight (BMI ≥

BACKGROUND/AIMS: This investigation aimed to estimate the value of regular follow-up programs after curative resection for colorectal cancer. METHODOLOGY: We compared the recurrence rate, rate of curative re-resection, and survival rate between groups who had either regular or irregular follow-up. The medical records of 397 consecutive patients, who underwent a curative resection for colorectal cancer between January 1994 and December 1997, were analyzed retrospectively. RESULTS: The recurrence

See Article on Page 192-197 Acute appendicitis is the most common indication for surgery in patients admitted to hospital due to an acute abdomen. Although most are uncomplicated, about 20% of all acute appendicitis cases are complicated, leading to local or diffuse peritonitis. An urgent appendectomy is the recommended treatment for both complicated and uncomplicated appendicitis. The appendectomy, which has been the first choice for the treatment of acute appendicitis for over 120 years, is

Purpose: The aim of this study is to evaluate the incidence of synchronous colonic lesions and to identify the impact of an incomplete preoperative colonoscopy in colorectal cancer patients. Methods: We studied 187 patients with colorectal cancer who received colonoscopic examinations pre or postoperatively in our hospital from January 2000 to March 2002. The pre and postoperative colonoscopic findings were reviewed. Most post-operative colonoscopies were performed 12 months after the operation,

BACKGROUND: The involvement of resection margins after rectal cancer surgery by malignant tumors is a negative prognostic factor. Therefore, it is important to analyze treatment outcomes and establish adjuvant therapy. METHODS: The Health Insurance Review and Assessment Service collects data from medical institutions in South Korea. We reviewed the database of this prospectively collected cohort for patients who underwent curative resection for rectal cancer. RESULTS: Of the 5,620 patients, 113
