There are many reasons why doctors would not to be able to communicate with patients. First, medicine is science or humanity? Although object of medicine is human, modern medicine tends to regard human as broken machine. Second, gastroenterologists are overloaded by treatment of patients, providing education, attending academic conference, and writing papers. Above all things, it is much worse for gastroenterologists because of endoscopic procedures. The other problem is attitude of modern society about human suffering. Sufferings come from not only body but also mind or spirit. Although there are may difficult problems, if doctors listen to patients' history by their side, it will help to restore their faith. In addition, we need humanity education and improvement plans for medical service system.

Colorectal cancer remains a significant health burden in South Korea, being the third most diagnosed cancer in the country. Despite advances in treatment, patients with metastatic colorectal cancer still face limited survival rates, with resection often deemed impossible for the majority. This review discusses the current state of chemotherapy in colorectal cancer treatment, focusing on both adjuvant chemotherapy post-surgery and palliative chemotherapy for metastatic cases. The article highlights recent updates in treatment guidelines, including the use of immunotherapy and the role of circulating tumor DNA (ctDNA) in personalized medicine. The integration of these novel approaches aims to enhance treatment efficacy, improve patient survival, and reduce recurrence rates, paving the way for more tailored and effective therapeutic strategies in colorectal cancer management.

Colorectal cancer (CRC) is the third most commonly diagnosed cancer in Korea. Despite recent developments in the treatment of CRC, the median overall survival time in patients with metastatic CRC is less than 30 months. The biologic agents that target the epidermal growth factor receptor (EGFR) or vascular endothelial growth factor (VEGF) have proven clinical benefits in the treatment of patient with metastatic CRC. Anti-EGFR agents, including cetuximab and panitumumab, as well as anti-VEGF agents, including bevacizumab, aflibercept, ramucirumab, and regorafenib have been shown to extend survival in combination with cytotoxic chemotherapy. In particular, the addition of anti-EGFR agents has demonstrated significant efficacy in patients with the RAS wild-type metastatic CRC. In the future, building a personalized treatment strategy, according to the clinical characteristics and biologic features of patients with unresectable or metastatic CRC, will be necessary. In this review, we summarized the mechanisms of target therapy, the results of main clinical trials, and the guideline of clinical practice in patients with unresectable or metastatic CRC.

Endoscopic mucosal resection (EMR) is an endoscopic alternative to surgical resection of mucosal and submucosal neoplastic lesions. Prior to the development of knives, EMR could be performed with accessories to elevate the lesion. After the development of various knives, en bloc resection was possible without other accessories. So, recently, simple snaring without suction or endoscopic submucosal dissection using knife in the epithelial lesions such as adenoma or early mucosal cancer has been performed. However, for easy and complete resection of subepithelial lesions such as carcinoid tumor, a few accessories are needed. Complete resection of rectal carcinoid tumors is difficult to achieve with conventional endoscopic resection techniques because these tumors often extend into the submucosa. The rate of positive resection margin for tumor is lower in the group of EMR using a cap (EMR-C) or EMR with a ligation device (EMR-L) than conventional EMR group. EMR-C and EMR-L (or endoscopic submucosal resection with a ligation device) may be a superior method to conventional EMR for removing small rectal carcinoid tumors.

BACKGROUND/AIMS: One major complication of endoscopic submucosal dissection (ESD) is delayed bleeding. Most hospitals routinely perform second-look endoscopy to reduce the chances of delayed bleeding without solid evidence supporting the practice. The aim of this study was to evaluate whether second-look endoscopy prevents delayed bleeding and to verify the clinicopathological features of delayed bleeding to determine how to identify lesions that may require second-look endoscopy. METHODS: We investigated 440 lesions in 397 patients who underwent ESD for gastric neoplasm from January 2008 to June 2010. Two-thirds of the enrolled cases were adenomas, and 290 lesions were located in the lower portion of the stomach. Clinically evident bleeding from mucosal defects 24 hours after ESD was considered as delayed bleeding. We reviewed the data, including the characteristics of patients, lesions, and procedures. Furthermore, the rate of delayed bleeding before and after second-look endoscopy, performed within three days of ESD, was investigated to determine the utility of second-look endoscopy. RESULTS: Delayed bleeding was evident in 9 of 440 lesions (2.0%), all of which underwent endoscopic hemostasis. The only significant factor predicting delayed bleeding was resected specimen over 40 mm in size (p=0.003). Delayed bleeding occurred in 8 of 9 cases (89%) before the second-look endoscopy, which was performed within 72 hours after ESD. CONCLUSIONS: In this study, second-look endoscopy may be useful for preventing post-ESD bleeding, especially when resected specimens are over 40 mm in size.
