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. (Korean J Gastroenterol 2012;60:162-165)

Background/Aims: Comparative genomic hybridization (CGH) is a new powerful technique for the molecular cytogenetic analysis of cancer. Methods: Twenty-five colorectal carcinomas were screened for chromosomal aberrations using CGH. Results: All carcinomas had chromosomal aberrations, and the mean number of chromosomal aberrations per tumor was 5.3. The cases of chromosomal gains were more common than the cases of chromosomal losses. The cases of amplification of 7q region, which contains locus of c-met, was significantly higher in stage III and IV than in stage I and II (p 0.05). In three cases of stage IV (67%), two showed amplification of 7q and 20q, in which c-met oncogene and c-src oncogene are located, respectively. The chromosomal gains of tumor were mostly detected at 20q, 7q, and 13q. The chromosomal losses of tumor were frequently detected at 17p and 18q. Conclusions: The CGH may be useful in predicting the prognosis or therapeutic decision of colorectal carcinoma. Especially, the chromosomal changes at 7q, 20q and 13q as well as c-met and c-src may be useful markers for colorectal carcinoma. (Korean J Gastroenterol 2002;39:275-283)

Polyps that contain carcinomatous changes that are confined to the mucosa (carcinoma-in-situ or severe dysplasia) do not have metastatic potential and are adequately treated with complete polypectomy or endoscopic mucosal resection. If deep invasion into the stalk has occurred or if adverse features (such as lymphatic invasion, or positive margins) are present, then en bloc colectomy is indicated. For lesions in the mid to upper rectum, a low anterior resection is the treatment of choice. To decrease the risk of local recurrence, patients should undergo optimal pelvic dissection with sharp mesorectal excision. Patients with pathologic lymph node-negative T3 or T4 lesions or any lymph node-positive cancer should receive preoperative or postoperative combined modality therapy. A major goal of preoperative therapy is to decrease the volume of the primary tumor and thus enhance sphincter preservation. For resectable colon cancer, the surgical procedure of choice is colectomy with en bloc removal of the regional lymph nodes. Laparoscopic colectomy has been advanced as an approach to the surgical management of colon cancer. Recently, the outcomes of cancer from a randomized trial comparing laparoscopically assisted and open surgery for curable colon cancer was reported. After a median of 4.4 years follow-up, similar cancer recurrence rates were observed in the two groups. The current management of disseminated metastatic colon cancer uses various active drugs, both in combination and as single agents: 5-FU/leucovorin, irinotecan, oxaliplatin, capecitabine, bevacizumab, and cetuximab. The choice of therapy is based on consideration of the type and timing of the prior therapy that has been administered and the differing toxicity profiles of the constituent drugs. As primary therapy for metastatic disease in a patient with good tolerance to intensive therapy, combination therapy consisting of fluoropyrimidines: FOLFOX (oxaliplatin, infusional fluorouracil, and leucovorin) or FOLFIRI (irinotecan, infusional fluorouracil, and leucovorin), with or without bevacizumab; bolus 5-FU/leucovorin/irinotecan with bevacizumab; 5-FU/leucovorin with bevacizumab were recommened.

Colorectal cancer (CRC) is the third most common cause of cancer-related death in the world. Although the long-term outcome of patients with metastatic CRC is still poor, target therapy including anti EGFR agents and anti VEGF agents and immunotherapy including anti PD-1 antibody and anti CTLA-4 antibody have shown clinical benefits in the treatment of patient with metastatic CRC. In the future, the personalized treatment strategy based on the clinical characteristics and biologic features of patients with metastatic CRC will be necessary. In this review, we summarized the mechanisms and clinical evidences of target therapy and immunotherapy, and the guideline of clinical practice in patients with metastatic CRC.

A 57-year-old male visited our hospital due to a growing abdominal mass for 1 month. The patient was diagnosed as transverse colon cancer with duodenal fistula, and then was treated with neoadjuvant concurrent chemoradiation therapy (2 cycles of FOLFOX-4, 3-dimensional conformal radiation therapy: 3,000 cGy in 10 fractions). Despite the improvement of colon cancer and associated inflammation, the symptom of colonic obstruction was aggravated. Thus transverse colon segmentectomy was done. After surgery, he have received adjuvant 12 cycles of FOLFOX-4 chemotherapy. Now, he is currently being followed up in cure state.

5-Fluorouracil (5-FU) has been widely used in the treatment of various solid tumors. However, 5-FU cardiotoxicity is being reported with increasing frequency. The main symptom of cardiotoxicity is chest pain at rest with ischemic electrocardiographic changes. Up until now, the underlying mechanism has been suspected to be coronary artery spasm. However, this chest pain associated with 5-FU has several characteristics that are incompatible with coronary artery spasm; eg, inefficacy of calcium-channel blocker and a slow increase in cardiac enzyme levels. We experienced a case of 5-FU-induced cardiotoxicity which showed clinical findings consistent with acute myocardial infarction. Based on the clinical findings, coronary angiography, and no stenosis was noted. However, we concluded that the cardiotoxicity in this case was due to ischemia caused by coronary artery spasm. Because vasodilatator was effective and secondary attack was followed.

Mucinous gastric carcinoma (MGC) is an unusual histologic subtype, and early detection of MGC is very rare. Early stage MGC appears as an elevated lesion resembling a submucosal tumor (SMT) due to abundant mucin pools in the submucosa or mucosa. We report a rare case of SMT-like early-stage MGC. Tumor type was predicted preoperatively based on characteristic endoscopic findings, in which an SMT-like mass was observed at the gastric fundus. The tumor was covered by nearly normal mucosa, but with an opening allowing for the passage of copious mucus discharge. A total gastrectomy with Roux-en Y esophagojejunostomy was subsequently performed. Histopathology of the tumor revealed early-stage (lamina propria) mucinous adenocarcinoma.

Recurrence of gastric cancer after 10 years of surgical resection is highly rare. There are limited data on the surveillance of patients with gastric cancer after 10 years from gastrectomy. A 50-year-old man presented to the gastroenterology clinic at our hospital for the management of abnormal findings on a routine colonoscopic exam. He had undergone gastrectomy for advanced gastric cancer 12 years ago. At presentation, colonoscopic examination revealed asymmetrically edematous and hyperemic mucosal change with luminal narrowing on transverse colon. Abdominal computed tomography showed no evidence of distant metastasis, except for focal bowel wall thickening on transverse colon. He underwent a laparoscopic right-hemicolectomy, and the resected specimen revealed a recurrent and metastatic lesion. We report a case of recurrence of gastric cancer after 10 years from surgical resection with relevant literature review. (Korean J Gastroenterol 2017;70:296-300)
