| 1 | Sex-dependent difference in the effect of metformin on colorectal cancer-specific mortality of diabetic colorectal cancer patients显示文摘AIM To assess factors associated with the higher effect of metformin on mortality in diabetic colorectal cancer(CRC) patients,since the factors related to the effectiveness of metformin have not been identified yet.METHODS Between January 2000 and December 2010,413 patients diagnosed with both stage 3/4 CRC and diabetes mellitus were identified. Patients' demographics and clinical characteristics were analyzed. The effect of metformin on CRC-specific mortality and the interactions between metformin and each adjusted factor were evaluated.RESULTS Total follow-up duration was median 50 mo(range: 1-218 mo). There were 85 deaths(45.9%) and 72 CRC-specific deaths(38.9%) among 185 patients who used metformin,compared to 130 total deaths(57.0%) and 107 CRC-specific deaths(46.9%) among 228 patients who did not use metformin. In multivariate analysis,survival benefit associated with metformin administration was identified(HR = 0.985,95%CI: 0.974-0.997,P = 0.012). Interaction test between metformin and sex after adjustment for relevant factors revealed that female CRC patients taking metformin exhibited a significantly lower CRC-specific mortality rate than male CRC patients taking metformin(HR = 0.369,95%CI: 0.155-0.881,P = 0.025). Furthermore,subgroup analysis revealed significant differences in CRC-specific mortality between the metformin and non-metformin groups in female patients(HR = 0.501,95%CI: 0.286-0.879,P = 0.013) but not male patients(HR = 0.848,95%CI: 0.594-1.211,P = 0.365). There were no significant interactions between metformin and other adjusted factors on CRC-specific mortality.CONCLUSION We showed a strong sex-dependent difference in the effect of metformin on CRC-specific mortality in advanced stage CRC patients with diabetes. | Jung Won Park Jin Ha Lee Ye Hyun Park Soo Jung Park Jae Hee Cheon Won Ho Kim Tae Il Kim | 2017 | World Journal of Gastroenterology2017，23，28： | 3 |
| 2 | Risk factors for postoperative recurrence after primary bowel resection in patients with Crohn's disease显示文摘AIM To evaluate the risk factors for postoperative recurrence after primary bowel resection in a cohort of Korean Crohn's disease(CD) patients.METHODS This study included 260 patients with no history of previous bowel surgery who underwent primary surgery for CD between January 2000 and December 2010 at Asan Medical Center(Seoul, South Korea). The median follow-up period was 101 mo.RESULTS During the follow-up period, 66 patients(25.4%) underwent a second operation for disease recurrence.At 1, 5 and 10 years after the first operation, the cumulative rate of surgical recurrence was 1.1%, 8.3% and 35.9% and clinical recurrence occurred in 1.2%, 23.6% and 68.1%, respectively. In multivariate analysis, undergoing an emergency operation was a significant risk factor for surgical recurrence-free survival(SRFS) [HR = 2.431, 95%CI: 1.394-4.240, P = 0.002], as were the presence of perianal disease after the first operation(HR = 1.715, 95%CI: 1.005-2.926, P = 0.048) and history of smoking(HR = 1.798, 95%CI: 1.088-2.969, P = 0.022). The postoperative use of antitumor necrosis factor(TNF) agents reduced SRFS risk(HR = 0.521, 95%CI: 0.300-0.904, P = 0.02).CONCLUSION History of smoking, postoperative perianal disease and undergoing an emergency operation were independent risk factors for surgical recurrence. Using anti-TNF agents may reduce surgical recurrence. | Kwan Mo Yang Chang Sik Yu Jong Lyul Lee Chan Wook Kim Yong Sik Yoon In Ja Park Seok-Byung Lim Sang Hyoung Park Byong Duk Ye Suk-Kyun Yang Jin Cheon Kim | 2017 | World Journal of Gastroenterology2017，23，38： | 3 |

| 5 | Clinical assessment and identification of immuno-oncology markers concerning the 19-gene based risk classifier in stage Ⅳ colorectal cancer显示文摘BACKGROUND Genomic profiling of tumors has contributed to the understanding of colorectal cancer(CRC), facilitating diagnosis, prognosis and selection of treatments,including targeted regimens. A report suggested that a 19-gene-based risk classifier(TCA19) was a prognostic tool for patients with stage III CRC. The survival outcomes in patients with stage IV CRC are still poor and appropriate selection of targeted therapies and immunotherapies is challenging.AIM To assess clinical implication of TCA19 in patients with stage IV CRC, and to identify TCA19 with involvement in immune-oncology.METHODS A retrospective review of the medical records of 60 patients with stage IV CRC was conducted, assessing clinicopathological variables and progression-free survival(PFS). TCA19 gene expression was determined by quantitative polymerase chain reaction(qPCR) in matched normal and tumor tissues taken from the study cohort. Expression of potential immune-oncology regulatory proteins and targets was examined by immunohistochemistry(IHC), western blot, immunofluorescence staining in tissues from a validation cohort of 10 patients, and in CRC cell lines co-cultured with monocyte in vitro.RESULTS In the patients with TCA19 score higher than the median, the PFS rates of eight patients who received the targeted regimens were significantly higher than the PFS rates of four patients who received 5-fluorouracil-based regimen(P = 0.041).In multivariate analysis, expression of signaling lymphocytic activation molecule family, member 7(SLAMF7) and triggering receptor expressed on myeloid cells 1(TREM1) was associated with PFS in the 60-patient cohort. After checking another 10 validate set, the expression of the IHC, the level of real-time qPCR,and the level of western blot were lower for SLAMF7 and higher for TREM7 in primary and metastatic tumors than in normal tissues. In CRC cells expressing SLAMF7 that were co-cultured with a monocytic cell line, levels of CD 68 and CD73 were significantly lower at day 5 of co-culture than at day 0.CONCLUSION The TCA19 score might be prognostic for target-regimen-specific PFS in stage IV CRC. Down-regulation of SLAMF7 and up-regulation of TREM1 occur in primary and metastatic tumor tissues. | Jong Lyul Lee Seon Ae Roh Chan Wook Kim Yi Hong Kwon Ye Jin Ha Seon-Kyu Kim Seon-Young Kim Dong-Hyung Cho Yong Sung Kim Jin Cheon Kim | 2019 | World Journal of Gastroenterology2019，25，11： | 1 |

| 10 | Evaluating the benefit of adjuvant chemotherapy in patients with ypT0-1 rectal cancer treated with preoperative chemoradiotherapy显示文摘BACKGROUND Adjuvant chemotherapy(ACTx)is recommended in rectal cancer patients after preoperative chemoradiotherapy(PCRT),but its efficacy in patients in the early post-surgical stage who have a favorable prognosis is controversial.AIM To evaluate the long-term survival benefit of ACTx in patients with ypT0–1 rectal cancer after PCRT and surgical resection.METHODS We identified rectal cancer patients who underwent PCRT followed by surgical resection at the Asan Medical Center from 2005 to 2014.Patients with ypT0–1 disease and those who received ACTx were included.The 5-year overall survival(OS)and 5-year recurrence-free survival(RFS)were analyzed according to the status of the ACTx.RESULTS Of 520 included patients,413 received ACTx(ACTx group)and 107 did not(no ACTx group).No significant difference was observed in 5-year RFS(ACTx group,87.9%vs no ACTx group,91.4%,P=0.457)and 5-year OS(ACTx group,90.5%vs no ACTx group,86.2%,P=0.304)between the groups.cT stage was associated with RFS and OS in multivariate analysis[hazard ratio(HR):2.57,95%confidence interval(CI):1.07–6.16,P=0.04 and HR:2.27,95%CI:1.09–4.74,P=0.03,respectively].Furthermore,ypN stage was associated with RFS and OS(HR:4.74,95%CI:2.39–9.42,P<0.00 and HR:4.33,95%CI:2.20–8.53,P<0.00,respectively),but only in the radical resection group.CONCLUSION Oncological outcomes of patients with ypT0–1 rectal cancer who received ACTx after PCRT showed no improvement,regardless of the radicality of resection.Further trials are needed to evaluate the efficacy of ACTx in these group of patients. | Ye Won Jeon In Ja Park Jeong Eun Kim Jin-Hong Park Seok-Byung Lim Chan Wook Kim Yong Sik Yoon Jong Lyul Lee Chang Sik Yu Jin Cheon Kim | 2021 | World Journal of Gastrointestinal Surgery2021，13，9： | 0 |
