| 1 | Development and validation of a risk score for advanced colorectal adenoma recurrence after endoscopic resection显示文摘AIM: To develop and validate a risk score for advanced colorectal adenoma(ACA) recurrence after endoscopic polypectomy.METHODS: Out of 3360 patients who underwent colon polypectomy at University of Foggia between 2004 and 2008, data of 843 patients with 1155 ACAs was retrospectively reviewed. Surveillance intervals were scheduled by guidelines at 3 years and primary endpoint was considered 3-year ACA recurrence. Baseline clinical parameters and the main features of ACAs were entered into a Cox regression analysis and variables with P < 0.05 in the univariate analysis were then tested as candidate variables into a stepwise Cox regression model(conditional backward selection). The regression coefficients of the Cox regression model were multiplied by 2 and rounded in order to obtain easy to use point numbers facilitating the calculation of the score. To avoid overoptimistic results due to model fitting and evaluation in the same dataset, we performed an internal 10-fold cross-validation by means of bootstrap sampling. RESULTS: Median lesion size was 16 mm(12-23) while median number of adenomas was 2.5(1-3), whereof the number of ACAs was 1.5(1-2). At 3 years after polypectomy, recurrence was observed in 229 ACAs(19.8%), of which 157(13.5%) were metachronous neoplasms and 72(6.2%) local recurrences. Multivariate analysis, after exclusion of the variable 'type of resection' due to its collinearity with other predictive factors, confirmed lesion size, number of ACAs and grade of dysplasia as significantly associated to the primary outcome. The score was then built by multiplying the regression coefficients times 2 and the cut-off point 5 was selected by means of a Receiver Operating Characteristic curve analysis. In particular, 248 patients with 365 ACAs fell in the higher-risk group(score ≥ 5) where 3-year recurrence was detected in 174 ACAs(47.6%) whereas the remaining 595 patients with 690 ACAs were included in the low-risk group(score < 5) where 3-year recurrence rate was 7.9%(55/690 ACAs). Area under the curve of the model was 0.81(0.72-0.86) with an overall classification error rate of 0.09. The model was finally validated by means of 10-fold cross validation.CONCLUSION: Our study provides support for the use of a novel risk score as a clinical predictor of ACA recurrence after colon polypectomy. | Antonio Facciorusso Marianna Di Maso Gaetano Serviddio Gianluigi Vendemiale Nicola Muscatiello | 2016 | World Journal of Gastroenterology2016，22，26： | 8 |
| 2 | Lymphocyte-to-monocyte ratio predicts survival after radiofrequency ablation for colorectal liver metastases显示文摘AIM: To test the correlation between lymphocyte-tomonocyte ratio(LMR) and survival after radiofrequency ablation(RFA) for colorectal liver metastasis(CLMs). METHODS: From July 2003 to Feb 2012, 127 consecutive patients with 193 histologically-proven unresectable CLMs were treated with percutaneous RFA at the University of Foggia. All patients had undergone primary colorectal tumor resection before RFA and received systemic chemotherapy. LMR was calculated by dividing lymphocyte count by monocyte count assessed at baseline. Treatment-related toxicity was defined as any adverse events occurred within 4 wk after the procedure. Overall survival(OS) and time to recurrence(TTR) were estimated from the date of RFA by Kaplan-Meier with plots and median(95%CI). The inferential analysis for time to event data was conducted using the Cox univariate and multivariate regression model to estimate hazard ratios(HR) and 95%CI. Statistically significant variables from the univariate Cox analysis were considered for the multivariate models.RESULTS: Median age was 66 years(range 38-88) and patients were prevalently male(69.2%). Median LMR was 4.38%(0.79-88) whereas median number of nodules was 2(1-3) with a median maximum diameter of 27 mm(10-45). Median OS was 38 mo(34-53) and survival rate(SR) was 89.4%, 40.4% and 33.3% at 1, 4 and 5 years respectively in the whole cohort. Running log-rank test analysis found 3.96% as the most significant prognostic cut-off point for LMR and stratifying the study population by this LMR value median OS resulted 55 mo(37-69) in patients with LMR > 3.96% and 34(26-39) mo in patients with LMR ≤ 3.96%(HR = 0.53, 0.34-0.85, P = 0.007). Nodule size and LMR were the only significant predictors for OS in multivariate analysis. Median TTR was 29 mo(22-35) with a recurrence-free survival(RFS) rate of 72.6%, 32.1% and 21.8% at 1, 4 and 5 years, respectively in the whole study group. Nodule size and LMR were confirmed as significant prognostic factors for TTR in multivariate Cox regression. TTR, when stratified by LMR, was 35 mo(28-57) in the group > 3.96% and 25 mo(18-30) in the group ≤ 3.96%(P = 0.02).CONCLUSION: Our study provides support for the use of LMR as a novel predictor of outcome for CLM patients. | Antonio Facciorusso Valentina Del Prete Nicola Crucinio Gaetano Serviddio Gianluigi Vendemiale Nicola Muscatiello | 2016 | World Journal of Gastroenterology2016，22，16： | 4 |
| 3 | Impact of sodium glucose cotransporter-2 inhibitors on liver steatosis/fibrosis/inflammation and redox balance in non-alcoholic fatty liver disease显示文摘BACKGROUND Sodium glucose cotransporter-2 inhibitors(SGLT2-I)are the most recently approved drugs for type 2 diabetes(T2D).Recent clinical trials of these compounds reported beneficial cardiovascular(CV)and renal outcomes.A major cause of vascular dysfunction and CV disease in diabetes is hyperglycemia associated with inflammation and oxidative stress.Pre-clinical studies demonstrated that SGLT2-I reduce glucotoxicity and promote anti-inflammatory effects by lowering oxidative stress.AIM To investigate the effects of SGLT2-I on markers of oxidative stress,inflammation,liver steatosis,and fibrosis in patients of T2D with non-alcoholic fatty liver disease(NAFLD).METHODS We referred fifty-two consecutive outpatients treated with metformin monotherapy and exhibiting poor glycemic control to our centre.We introduced the outpatients to an SGLT2-I(dapagliflozin,empagliflozin,or canagliflozin;n=26)or a different hypoglycemic drug[other glucose-lowering drugs(OTHER),n=26].We evaluated circulating interleukins and serum hydroxynonenal(HNE)-or malondialdehyde(MDA)-protein adducts,fatty liver index(FLI),NAFLD fibrosis score,aspartate aminotransferase(AST)/alanine aminotransferase(ALT)ratio,AST-to-platelet-ratio index(APRI),and fibrosis-4 on the day before(T0)and following treatment for six months(T1).We also performed transient elastography at T0 and T1.RESULTS Add-on therapy resulted in improved glycemic control and reduced fasting blood glucose in both groups.Of note,following treatment for six months,a reduction of FLI and APRI,as well as of the FibroScan result,was reported in patients treated with SGLT2-I,but not in the OTHER group;furthermore,in the SGLT2-I group,we reported lower circulating levels of interleukin(IL)-1β,IL-6,tumor necrosis factor,vascular endothelial growth factor,and monocyte chemoattractant protein-1,and higher levels of IL-4 and IL-10.We did not observe any modification in circulating interleukins in the OTHER group.Finally,serum HNE-and MDA-protein adducts decreased significantly in SGLT2-I rather than OTHER patients and correlated with liver steatosis and fibrosis scores.CONCLUSION The present data indicate that treatment with SGLT2-I in patients with T2D and NAFLD is associated with improvement of liver steatosis and fibrosis markers and circulating pro-inflammatory and redox status,more than optimizing glycemic control. | Francesco Bellanti Aurelio Lo Buglio MichałDobrakowski Aleksandra Kasperczyk Sławomir Kasperczyk Palok Aich Shivaram P Singh Gaetano Serviddio Gianluigi Vendemiale | 2022 | World Journal of Gastroenterology2022，28，26： | 3 |
