| 1 | Laparoscopy-assisted pylorus-preserving gastrectomy for early gastric cancer: A retrospective study of long-term functional outcomes and quality of life显示文摘BACKGROUND Laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) was known to have benefits of function-preserving surgery compared to laparoscopy-assisted distal gastrectomy (LADG). However, in clinical settings, delayed gastric emptying and esophageal reflux following LAPPG can be serious issues, making surgeons reluctant to perform LAPPG. It is unclear that LAPPG had better longterm functional outcomes and quality of life compared to LADG. AIM To evaluate the long-term functional outcomes and patient-reported quality of life of LAPPG compared to those of LADG. METHODS We reviewed the clinicopathological data of 195 patients who underwent LADG with Billroth II anastomosis and 101 patients who underwent LAPPG for cT1N0 gastric cancer in the middle third of the stomach between 2012 and 2015. Postoperative complications, nutritional parameters, and survey results of the European Organization for Research and Treatment of Cancer Questionnaire C30 and STO22 questionnaire were compared between the two groups. RESULTS The serum hemoglobin level was significantly higher in the LAPPG group than in the LADG group (P < 0.001). In the endoscopic findings, incidence of bile reflux was lower (P < 0.001);however, the incidence of residual food was higher in the LAPPG group than in the LADG group (P < 0.001). Regarding the quality of life score, the LAPPG group had a better physical functioning score (86.7 vs 90.0, P = 0.032) but also greater pain and reflux when compared to the LADG group [8.3 vs 16.7 in pain, 11.1 (interquartile range, 0, 22.2) vs 11.1 (interquartile range, 11.1, 33.3) in reflux, P = 0.034 and 0.001, respectively]. CONCLUSION LAPPG is beneficial to recovery of anemia and to bile reflux, however, it might be unfavorable in terms of pain and reflux symptoms compared to LADG with Billroth II anastomosis. | Bang Wool Eom Boram Park Hong Man Yoon Keun Won Ryu Young-Woo Kim | 2019 | World Journal of Gastroenterology2019，25，36： | 18 |
| 2 | A comparative study of totally laparoscopic distal gastrectomy versus laparoscopic-assisted distal gastrectomy in gastric cancer patients: Short-term operative outcomes at a high-volume center显示文摘Objective: Laparoscopic gastrectomy has been established as a standard treatment for early gastric cancer, and its use is increasing recently. Compared with the conventional laparoscopy-assisted distal gastrectomy(LADG), totally laparoscopic distal gastrectomy(TLDG) involves intracorporeal reconstruction, which can avoid the additional incision, resulting in pain reduction and early recovery. This study aimed to compare the short-term postoperative outcomes of TLDG vs. LADG in gastric cancer in a high-volume center.Methods: A retrospective cohort study was conducted on 1,322 patients who underwent laparoscopic distal gastrectomy from June 2012 to June 2017 at the National Cancer Center, Korea. LADG was performed in the early period before July 2015, and TLDG was applied in the later period. Postoperative short-term outcomes were compared in terms of complication and clinical course between the two groups. Pain score was measured by rating the pain intensity from 0 to 10 points on postoperative day(POD) 1 and 3.Results: A total of 667 patients underwent LADG and 655 patients underwent TLDG. Clinicopathologic characteristics were not different in both groups. Intraoperative estimated blood loss(EBL) was significantly lower in the TLDG group(P<0.001). Postoperative pain scores were significantly lower in the TLDG group than in the LADG group on POD 1(5.1±1.5 vs. 4.8±1.4, P=0.015). First flatus passage after operation was significantly earlier in the TLDG group(3.4±0.8 d vs. 3.2±0.6 d, P<0.001). There were no differences in postoperative complications and hospital stay between the two groups.Conclusions: Based on the reported short-term postoperative outcomes, TLDG is safe and feasible as well as LADG. Moreover, compared with LADG, TLDG can reduce intraoperative EBL and postoperative pain and enhance the bowel motility in gastric cancer surgery. | Won Ho Han Amir Ben Yehuda Deok-Hee Kim Seung Geun Yang Bang Wool Eom Hong Man Yoon Young-Woo Kim Keun Won Ryu | 2018 | Chinese Journal of Cancer Research2018，30，5： | 11 |
| 3 | Individual having a parent with early-onset gastric cancer may need screening at younger age显示文摘AIM: To evaluate whether individuals with gastric cancer(GC) are diagnosed earlier if they have firstdegree relatives with GC.METHODS: A total of 4282 patients diagnosed with GC at National Cancer Center Hospital from 2002 to 2012 were enrolled in this retrospective study. We classified the patients according to presence or absence of first-degree family history of GC and compared age at diagnosis and clinicopathologic characteristics. In addition, we further classified patients according to specific family member with GC(father, mother, sibling, or offspring) and compared age at GC diagnosis among these patient groups. Baseline characteristics were obtained from a prospectively collected database. Information about the family member's age at GC diagnosis was obtained by questionnaire.RESULTS: A total of 924 patients(21.6%) had a firstdegree family history of GC. The mean age at GC diagnosis in patients having paternal history of GC was 54.4 ± 10.4 years and was significantly younger than in those without a first-degree family history(58.1 ± 12.0 years, P < 0.001). However, this finding was not observed in patients who had an affected mother(57.2 ± 10.0 years) or sibling(62.2 ± 9.8 years). Among patients with family member having early-onset GC(< 50 years old), mean age at diagnosis was 47.7 ± 10.3 years for those with an affected father, 48.6 ± 10.4 years for those with an affected mother, and 57.4 ± 11.5 years for those with an affected sibling. Thus, patients with a parent diagnosed before 50 years of age developed GC 10.4 or 9.5 years earlier than individuals without a family history of GC(both P <0.001).CONCLUSION: Early-onset GC before age of 50 was associated with parental history of early-onset of GC. Individual having such family history need to start screening earlier. | Hee-Won Kwak Il Ju Choi Chan Gyoo Kim Jong Yeul Lee Soo-Jeong Cho Bang Wool Eom Hong Man Yoon Jungnam Joo Keun Won Ryu Young-Woo Kim | 2015 | World Journal of Gastroenterology2015，21，15： | 7 |
| 4 | Recent updates and current issues of sentinel node navigation surgery for early gastric cancer显示文摘With the increase in the incidence of early gastric cancer(EGC),several endoscopic and laparoscopic approaches,such as endoscopic submucosal dissection and function-preserving gastrectomy,have been accepted as standard treatments.Sentinel node navigation surgery(SNNS)is an ideal surgical option for preservation of most parts of the stomach and consequent maintenance of normal gastric function to improve quality of life in patients with EGC.Although many previous studies and clinical trials have demonstrated the safety and feasibility of the sentinel node concept in gastric cancer,the clinical application of SNNS is debatable.Several issues regarding technical standardization and oncological safety need to be resolved.Recently several studies to resolve these problems are being actively performed,and SNNS might be an important surgical option in the treatment of gastric cancer in the future. | Sung Gon Kim Bang Wool Eom Hong Man Yoon Chan Gyoo Kim Myeong-Cherl Kook Young-Woo Kim Keun Won Ryu | 2021 | Chinese Journal of Cancer Research2021，33，2： | 7 |
| 5 | Predictive value of E-cadherin and Ep CAM for detection of metastatic lymph node in early gastric cancer显示文摘Objective:There has been a demand for a tumor-specific marker for metastatic lymph nodes in sentinel navigation surgery for gastric cancer.The aim of this study is to analyze protein expression in both primary tumors and metastatic lymph nodes in early gastric cancer patients.Methods:We collected primary tumors and metastatic lymph nodes from 71 patients who underwent curative gastrectomy and pathologically diagnosed with T1 N1 or T1 N2(8 th Union for International Cancer Control 8 th edition/American Joint Committee on Cancer staging system)gastric cancer.Immunohistochemistry was used to determine the expression of six cell membrane proteins,including carcinoembryonic antigen(CEA),E-cadherin,epithelial cell adhesion molecule(Ep CAM),P-cadherin,CD44 v6,and c-erb B2 in the patient samples.Results:The expression of CEA,E-cadherin,Ep CAM,P-cadherin,CD44 v6 and c-erb B2 in the evaluable primary tumor samples was 75.4%,97.1%,100%,89.9%,11.1%and 7.2%,respectively.Among cases wherein both the primary tumor and metastatic lymph nodes were evaluable,double positivity(expression in both primary tumor and metastatic lymph nodes)was observed for CEA,E-cadherin,Ep CAM,P-cadherin,CD44 v6 and c-erb B2 in 53.2%,97.9%,98.1%,76.6%,0 and 6.8%of the cases,respectively.The proportion of metastatic lymph nodes positive for CEA,E-cadherin,Ep CAM,P-cadherin,CD44 v6 and c-erb B2 was 71.4%,100%,98.1%,83.7%,0,and75%,respectively in primary tumors positive for the same markers.Conclusions:E-cadherin and Ep CAM had an overlap of 100%and 98.1%between the primary tumor and metastatic lymph nodes,respectively.Thus,E-cadherin and Ep CAM are potential molecular markers to detect metastatic lymph nodes in patients with early gastric cancer. | Bang Wool Eom Keun Won Ryu Hong Man Yoon Myeong-Cherl Kook | 2020 | Chinese Journal of Cancer Research2020，32，5： | 7 |
| 6 | Current status and challenges in sentinel node navigation surgery for early gastric cancer显示文摘Although a number of feasibility studies for sentinel node(SN) concepts in gastric cancer have been conducted since 2000, there remains a debate regarding detailed detection techniques and oncological safety. Two important multicenter phase II clinical trials were performed in Japan that used different methods and reached different conclusions; one confirmed acceptable results with a false-negative rate of 7%, and the other showed an unacceptably high false-negative rate of 46.4%. The Sentinel Node Oriented Tailored Approach(SENORITA)trial is a multicenter randomized controlled phase III trial being performed in Korea. Patient enrollment is now complete and the long-term results are currently awaited. Recently, an image-guided SN mapping technique using infrared ray/fluorescence was introduced. This method might be a promising technology because it allows the clear visualization of SNs. With regard to the primary tumor, the non-exposed endoscopic wall-inversion surgery technique and non-exposure endolaparoscopic full-thickness resection with simple suturing technique have been reported. These methods prevent abdominal infection and tumor seeding and can be good alternatives to conventional laparoscopic gastric wedge resection. For indications, SN navigation surgery can be extended to patients who underwent non-curative endoscopic resection. Although a few studies have been performed on these patients, sentinel concepts may be beneficial to patients as they omit the need for additional gastrectomy. SN navigation surgery can lead to actual organ-preserving surgery and plays a key role in improving the quality of life of patients with early gastric cancer in the future. | Bang Wool Eom Young-II Kim Hong Man Yoon Soo-Jeong Cho Jong Yeul Lee Chan GyooKim Soo Jin Kim Ji Yoon Rho Seok Ki Kim Myeong-Cherl Kook Young-Woo Kim Keun Won | 2017 | Chinese Journal of Cancer Research2017，29，2： | 5 |
| 7 | Gastric choriocarcinoma admixed with an α-fetoprotein-producing adenocarcinoma and separated adenocarcinoma显示文摘We report a case of gastric choriocarcinoma admixed with an α-fetoprotein (AFP)-producing adeno-carcinoma. A 70-year-old man was hospitalized for gastric cancer that was detected during screening by esophagogastroduodenoscopy (EGD). Initial laboratory data showed the increased serum level of AFP and EGD revealed a 5-cm ulcerofungating mass in the greater curvature of the gastric antrum. The patient underwent radical subtotal gastrectomywith D2 lymph node dissection and Billroth gastrojejunostomy. Histopathological evaluation confirmed double primary gastric cancer: gastric choriocarcinoma admixed with an AFP-producing adenocarcinoma and separated adenocarcinoma. At 2 wk postoperatively, his human chorionic gonadotropin and AFP levels had reduced and six cycles of adjuvant chemotherapy were initiated. No recurrence or distant metastasis was observed at 4 years postoperatively. | Bang Wool Eom So-Youn Jung Hongman Yoon Myeong-Cherl Kook Keun Won Ryu Jun Ho Lee Young-Woo Kim | 2009 | World Journal of Gastroenterology2009，15，40： | 4 |

| 9 | Improvement of diabetes and hypertension after gastrectomy: A nationwide cohort study显示文摘AIM: To evaluate the effect of gastrectomy on diabetes mellitus(DM) and hypertension(HTN) in non-obese gastric cancer patients. METHODS: A total of 100000 patients, diagnosed with either type 2 DM or HTN, were randomly selected from the 2004 Korean National Health Insurance System claims. Among them, 360 diabetes and 351 hypertensive patients with gastric cancer who had been regularly treated without chemotherapy from January 2005 to December 2010 were selected. They were divided into three groups according to their treatment methods: total gastrectomy(TG), subtotal gastrectomy(STG) and endoscopic resection(ER). RESULTS: The drug discontinuation rate of antidiabetic and anti-hypertensive agents after gastric cancer treatment was 9.7% and 11.1% respectively. DM appeared to be improved more frequently(22.8%) and earlier(mean ± SE 28.6 ± 1.8 mo) in TG group than in the two other groups [improved in 9.5% of ER group(37.4 ± 1.1 mo) and 6.4% of STG group(47.0 ± 0.8 mo)]. The proportion of patients treated with multiple drugs decreased more notably in TG group compared to others(P = 0.001 in DM, and P = 0.035 in HTN). In TG group, adjusted hazard ratio for theimprovement of DM was 2.87(95%CI: 1.15-7.17) in a multi-variate analysis and better control of DM was observed with survival analysis(P < 0.001).CONCLUSION: TG was found to decrease the need for anti-diabetic medications which can be reflective of improved glycemic control, to a greater extent than either ER or STG in non-obese diabetic patients. | Eun Kyung Lee So Young Kim You Jin Lee Mi Hyang Kwak Hak Jin Kim Il Ju Choi Soo-Jeong Cho Young Woo Kim Jong Yeul Lee Chan Gyoo Kim Hong Man Yoon Bang Wool Eom Sun-Young Kong Min Kyong Yoo Jong Hyock Park Keun Won Ryu | 2015 | World Journal of Gastroenterology2015，21，4： | 3 |
| 10 | Intravenous iron supplementation may be superior to observation in acute isovolemic anemia after gastrectomy for cancer显示文摘AIM:To determine whether the application of postoperative intravenous(IV)-iron for acute isovolemic anemia after gastrectomy for cancer may be effective.METHODS:Among 2078 gastric cancer patients who underwent surgery between February 2007 and August2009 at the National Cancer Center Korea,368 patients developed post-operative anemia[hemoglobin-(Hb)-level<9 g/dL]within the first postoperative week.Patients requiring transfusions were excluded.IV-iron was administered to 63 patients(iron group).Sixty patients were observed without treatment(observation group).The clinical outcomes of the groups were compared concerning clinicopathologic data,morbidity,and changes in Hb levels using Fisher’s exact test,Student’s t-test and the Z-test.RESULTS:The initial Hb level was higher in the iron group than in the observation group(7.3±1.0 g/dL vs8.4±0.5 g/dL,P<0.001).The slope of the changes in the Hb level was significantly higher in the iron group than in the observation group(0.648±0.054 vs 0.349±0.038,P<0.001).The Hb level 1 and 3 mo postoperatively increased from 10.7±1.3 to 11.9±1.3g/dL in the iron group(P=0.033)and from 10.1±1.0to 10.8±1.4 g/dL in the observation group(P<0.001).The postoperative hospital stay was significantly longer in the iron group than in the observation group(10.5±6.8 d vs 7.6±5.5 d,P=0.011).There were no significant differences in the major and surgical complications between the groups(6.3%vs 13.3%,P=0.192;9.5%vs 3.3%,P=0.164).CONCLUSION:IV-iron supplementation may be an effective treatment for post-operative isovolemic postgastrectomy anemia and may be a better alternative than observation. | Hong Man Yoon Young-Woo Kim Byung Ho Nam Daniel Reim Bang Wool Eom Ji Yeon Park Keun Won Ryu | 2014 | World Journal of Gastroenterology2014，20，7： | 2 |
