1Prognostic significance of the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with stage Ⅲ and Ⅳcolorectal cancer显示文摘AIM To evaluate the prognostic value of the neutrophil-tolymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) in patients with colorectal cancer(CRC).METHODS Between April 1996 and December 2010, medical records from a total of 1868 patients with CRC were retrospectively reviewed. The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and Cox regression models.RESULTS The median follow-up duration was 46 mo(interquartile range, 22-73). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR (≥ 3.0) and high PLR(≥ 160) were independent risk factors predicting poor long-term outcomes in patients with stage Ⅲ and Ⅳ CRC. However, high NLR and high PLR were not prognostic factors in patients with stage Ⅰ and Ⅱ CRC.CONCLUSION In this study, we identified that high NLR (≥ 3.0) and high PLR (≥ 160) are useful prognostic factors to predict long-term outcomes in patients with stage Ⅲ and Ⅳ CRC.Jae Hyun Kim Jun Yeop Lee Hae Koo Kim Jin Wook Lee Sung Gyu Jung Kyoungwon Jung Sung Eun Kim Won Moon Moo In Park Seun Ja Park 2017World Journal of Gastroenterology2017,23,3:16
2Evaluation of esophageal function in patients with esophageal motor abnormalities using multichannel intraluminal impedance esophageal manometry显示文摘AIM: To evaluate the functional aspect of esophageal motility in healthy subjects and in patients who were referred for esophageal function testing using multichannel intraluminal impedance-esophageal manometry (MII-EM), and to assess the clinical utility of MII-EM. METHODS: From September 2003 to January 2004, we performed the MII-EM on healthy volunteers and all the patients who were referred for esophageal function testing. Each patient received 10 liquid and 10 viscous swallows. We analyzed the results, the impedance and the manometric findings. Some of the subjects had additional ambulatory 24-h pH study performed to diagnose gastroesophageal reflux disease (GERD). RESULTS: Among 89 studied subjects, the MII-EM findings showed normal esophageal motility in 50 (56.17%), ineffective esophageal motility (IEM) in 17 (19.10%), nutcracker esophagus in 7 (7.86%), achalasia in 4 (4.49%), and scleroderma esophagus in 11 (12.35%) cases. The completeness and the speed of bolus transit were in the order of nutcracker esophagus, normal manometry and IEM. Some of the swallows showing normal manometry and IEM had incomplete transit. In the achalasia and scleroderma esophagus, almost all the swallows had incomplete transit. The body amplitudes were higher for the swallows with complete transit than for the swallows with incomplete transit. There was not a significant difference in the manometric and impedance findings between the subjects with and without GERD. CONCLUSION: MII-EM is a useful tool in assessing theesophageal function in the patients having esophageal motility abnormality. The primary factors influencing the bolus transit are the amplitude of the esophageal body and normal peristalsis.Yu Kyung Cho Myung-Gyu Choi Jae Myung Park Jung Hwan Oh Chang Nyol Paik Joon Wook Lee In Seok Lee Sang Woo Kim In-Sik Chung 2006World Journal of Gastroenterology2006,12,39:8
3Effect of gadolinium incorporation on optical characteristics of YNbO_4:Eu^(3+) phosphors for lamp applications显示文摘Eu3+-doped (Y,Gd)NbO4 phosphor was synthesized by solid-state reaction for possible application in cold cathode fluorescent lamps. A broad absorption band with peak maximum at 272 nm was observed which was due to the charge transfer between Eu3+ ions and neighboring oxygen anions. A deep red emission at the peak wavelength of 612 nm was observed which could be attributed to the 5D0→7F2 transition in Eu3+ ions. The highest luminance for Y1-x-yGdyNbO4:Eux3+ under 254 nm excitation was achieved at Eu3+ concentration of 18 mol.% (x=0.18) and Gd3+ concentration of 8.2 mol.% (y=0.082). The luminance of Y0.738Gd0.082NbO4:Eu3+0.18 was higher than that of a typical commercial phosphor Y2O3:Eu3+ and the CIE chromaticity coordinate was (0.6490, 0.3506), which was deeper than that of Y2O3:Eu3+. The particle size of the synthesized phosphors was controlled by the NaCl flux and particle size as high as 8 μm with uniform size distribution of particles was obtained.Sung Hwan Choi G.

53-Dimensional liver volume assessment in patients with hepatitis B virus-related liver cirrhosis during long-term oral nucleos(t)ide analogues therapy显示文摘AIM To assess the effect of long-term oral nucleos(t)ide analogues(NUCs) therapy on liver volume change in patients with suppress hepatitis B virus(HBV)-related liver cirrhosis.METHODS We reviewed the data of na?ve patients with HBVrelated liver cirrhosis, who had taken oral NUCs therapy, between 2003 and 2007 at Chonbuk University Hospital. We analyzed two consecutive sets of abdominal computerized tomography scans-one at the time oftreatment initiation and another at the second-year follow-up. Liver volume was calculated by 3-dimensional liver extraction volumetry program.RESULTS A total of 55 patients(34 males) were included. There was 114.3 m L ± 167.8 m L(12.9% ± 17.9%) of increase in liver volume during the two years of NUCs therapy(993.8 m L ± 242.8 m L at baseline vs 1108.1 m L ± 263.3 m L at two-year follow-up, P < 0.001). The ratio of the measured baseline liver volume to the estimated standard liver volume was improved from 70.8% to 78.0%. An increase in liver volume was shown not only in patients with compensated cirrhosis(P = 0.046) but also in those with decompensated cirrhosis(P < 0.001). Significant factors for volume increases were Child-Turcotte-Pugh grade and model for end-stage liver disease score improvement without virological breakthrough. In multiple linear regression analysis, delta albumin and delta alanine aminotransferase levels showed a significant association with the increase in liver volume(P = 0.002 and 0.005, respectively).CONCLUSION Long-term oral NUCs therapy in patients with HBVrelated liver cirrhosis lead to significant increase in liver volume assessed with 3-dimensional liver extraction volumetry program.Chang Hun Lee In Hee Kim Jin Chang Moon Seung Young Seo Seong Hun Kim Sang Wook Kim Seung Ok Lee Soo Teik Lee Dae Ghon Kim Jae Do Yang Hee Chul Yu 2017World Journal of Gastroenterology2017,23,2:6
6Ulva and Enteromorpha(Ulvaceae,Chlorophyta) from two sides of the Yellow Sea:analysis of nuclear rDNA ITS and plastid rbcL sequence data显示文摘Ulvacean green seaweeds are common worldwide;they formed massive green tides in the Yellow Sea in recent years,which caused marine ecological problems as well as a social issue.We investigated two major genera of the Ulvaceae,Ulva and Enteromorpha,and collected the plastid rbcL and nuclear ITS sequences of specimens of the genera in two sides of the Yellow Sea and analyzed them.Phylogenetic trees of rbcL data show the occurrence of five species of Enteromorpha(E.compressa,E.flexuosa,E.intestinalis,E.linza and E.prolifera) and three species of Ulva(U.pertusa,U.rigida and U.ohnoi).However,we found U.ohnoi,which is known as a subtropical to tropical species,at two sites on Jeju Island,Korea.Four ribotypes in partial sequences of 5.8S rDNA and ITS2 from E.compressa were also found.Ribotype network analysis revealed that the common ribotype,occurring in China,Korea and Europe,is connected with ribotypes from Europe and China/Japan.Although samples of the same species were collected from both sides of the Yellow Sea,intraspecific genetic polymorphism of each species was low among samples collected worldwide.王金锋 李楠 姜鹏 BOO Sung Min LEE Wook Jae 崔玉琳 林瀚智 赵瑾 刘正一 秦松 2010Chinese Journal of Oceanology and Limnology2010,28,4:6
7Double layered self-expanding metal stents for malignant esophageal obstruction, especially across the gastroesophageal junction显示文摘AIM: To evaluate the clinical outcomes of double-layered self-expanding metal stents (SEMS) for treatment of malignant esophageal obstruction according to whether SEMS crosses the gastroesophageal junction (GEJ). METHODS: Forty eight patients who underwent the SEMS insertion for malignant esophageal obstruction were enrolled. Patients were classified as GEJ group (SEMS across GEJ, 18 patients) and non-GEJ group (SEMS above GEJ, 30 patients) according to SEMS position. Double layered (outer uncovered and inner covered stent) esophageal stents were placed. RESULTS: The SEMS insertion and the clinical improvement were achieved in all patients in both groups. Stent malfunction occurred in seven patients in the GEJ group and nine patients in the non-GEJ group. Tumor overgrowth occurred in five and eight patients, respectively, food impaction occurred in one patient in each group, and stent migration occurred in one and no patient, respectively. There were no significant differences between the two groups. Reflux esophagitis occurred more frequently in the GEJ group (eight vs five patients, P = 0.036) and was controlled by proton pump inhibitor. Aspiration pneumonia occurred in zero and five patients, respectively, and tracheoesophageal fistula occurred in zero and two patients, respectively. CONCLUSION: Double-layered SEMS are a feasible and effective treatment when placed across the GEJ for malignant esophageal obstruction. Double-layered SEMS provide acceptable complications, especially migration, although reflux esophagitis is more common in the GEJ group.Min Dae Kim Su Bum Park Dae Hwan Kang Jae Hyung Lee Cheol Woong Choi Hyung Wook Kim Chung Uk Chung Young Il Jeong 2012World Journal of Gastroenterology2012,18,28:5
8Assessment of scoring systems for acute-on-chronic liver failure at predicting short-term mortality in patients with alcoholic hepatitis显示文摘AIM To assess the performance of proposed scores specific for acute-on-chronic liver failure in predicting shortterm mortality among patients with alcoholic hepatitis.METHODS We retrospectively collected data from 264 patients with clinically diagnosed alcoholic hepatitis from January to December 2013 at 21 academic hospitals in Korea. The performance for predicting short-term mortality was calculated for Chronic Liver FailureSequential Organ Failure Assessment(CLIF-SOFA), CLIF Consortium Organ Failure score(CLIF-C OFs), Maddrey'sdiscriminant function(DF), age, bilirubin, international normalized ratio and creatinine score(ABIC), Glasgow Alcoholic Hepatitis Score(GAHS), model for end-stage liver disease(MELD), and MELD-Na.RESULTS Of 264 patients, 32(12%) patients died within 28 d. The area under receiver operating characteristic curve of CLIF-SOFA, CLIF-C OFs, DF, ABIC, GAHS, MELD, and MELD-Na was 0.86(0.81-0.90), 0.89(0.84-0.92), 0.79(0.74-0.84), 0.78(0.72-0.83), 0.81(0.76-0.86), 0.83(0.78-0.88), and 0.83(0.78-0.88), respectively, for 28-d mortality. The performance of CLIF-SOFA had no statistically significant differences for 28-d mortality. The performance of CLIF-C OFs was superior to that of DF, ABIC, and GAHS, while comparable to that of MELD and MELD-Na in predicting 28-d mortality. A CLIF-SOFA score of 8 had 78.1% sensitivity and 79.7% specificity, and CLIF-C OFs of 10 had 68.8% sensitivity and 91.4% specificity for predicting 28-d mortality.CONCLUSION CLIF-SOFA and CLIF-C OF scores performed well, with comparable predictive ability for short-term mortality compared to the commonly used scoring systems in patients with alcoholic hepatitis.Hee Yeon Kim Chang Wook Kim Tae Yeob Kim Do Seon Song Dong Hyun Sinn Eileen L Yoon Young Kul Jung Ki Tae Suk Sang Soo Lee Chang Hyeong Lee Tae Hun Kim Jeong Han Kim Hyung Joon Yim Sung Eun Kim Soon Koo Baik Byung Seok Lee Jae Young Jang Young Seok Kim Sang Gyune Kim Jin Mo Yang Joo Hyun Sohn Heon Ju Lee Seung Ha Park Eun Hee Choi Dong Joon Kim Korean Acute-on-Chronic Liver Failure Study Group 2016World Journal of Gastroenterology2016,22,41:5
9Inhibitory effect of Jeju endemic seaweeds on the production of pro-inflammatory mediators in mouse macrophage cell line RAW 264.7显示文摘Seaweed has been used in traditional cosmetics and as a herbal medicine in treatments for cough,boils,goiters,stomach ailments,and urinary diseases,and for reducing the incidence of tumors,ulcers,and headaches.Despite the fact that seaweeds are frequently used in the practice of human health,little is known about the role of seaweed in the context of inflammation.This study aimed to investigate the influence of Jeju endemic seaweed on a mouse macrophage cell line(RAW 264.7) under the stimulation of lipopolysaccharide(LPS).Ethyl acetate extracts obtained from 14 different kinds of Jeju seaweeds were screened for inhibitory effects on pro-inflammatory mediators.Our results revealed that extracts from five seaweeds,Laurencia okamurae,Grateloupia elliptica,Sargassum thun-bergii,Gloiopeltis furcata,and Hizikia fusiformis,were potent inhibitors of the production of pro-inflammatory mediators such as nitric oxide(NO),prostaglandin E2(PGE2),interleukin-6(IL-6),and tumor necrosis factor-α(TNF-α).Based on these results,the anti-inflammatory effects and low cell toxicity of these seaweed extracts suggest potential thera-peutic applications in the regulation of the inflammatory response.Eun-Jin YANG Ji-Young MOON Min-Jin KIM Dong Sam KIM Chan-Shick KIM Wook Jae LEE Nam Ho LEE Chang-Gu HYUN 2010Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2010,11,5:5
10Single hepatocellular carcinoma ≤ 3 cm in left lateral segment:Liver resection or radiofrequency ablation?显示文摘AIM:To evaluate the long-term results of radiofrequency ablation(RFA)compared to left lateral sectionectomy(LLS)in patients with Child-Pugh class A disease for the treatment of single and small hepatocellular carcinoma(HCC)in the left lateral segments.METHODS:We retrospectively reviewed the data of133 patients with single HCC(≤3 cm)in their left lateral segments who underwent curative LLS(n=66)or RFA(n=67)between 2006 and 2010.RESULTS:The median follow-up period was 33.5mo in the LLS group and 29 mo in the RFA group(P=0.060).Most patients had hepatitis B virus-related HCC.The hospital stay was longer in the LLS group than in the RFA group(8 d vs 2 d,P<0.001).The 1-,2-,and 3-year disease-free survival and overall survival rates were 80.0%,68.2%,and 60.0%,and 95.4%,92.3%,and 92.3%,respectively,for the LLS group;and 80.8%,59.9%,and 39.6%,and 98.2%,92.0%,and 74.4%,respectively,for the RFA group.The disease-free survival curve and overall survival curve were higher in the LLS group than in the RFA group(P=0.012 and P=0.013,respectively).Increased PIVKA-Ⅱlevels and small tumor size were associated with HCC recurrence in multivariate analysis.CONCLUSION:Liver resection is suitable for single HCC≤3 cm in the left lateral segments.Jong Man Kim Tae Wook Kang Choon Hyuck David Kwon Jae-Won Joh Justin Sangwook Ko Jae Berm Park Hyunchul Rhim Joon Hyeok Lee Sung Joo Kim Seung Woon Paik 2014World Journal of Gastroenterology2014,20,14:4
11Temporal trends in the misdiagnosis rates between Crohn's disease and intestinal tuberculosis显示文摘AIM To investigate the temporal trends in the misdiagnosis rate between Crohn's disease(CD) and intestinal tuberculosis(ITB) in South Korea. METHODS We retrospectively reviewed the medical records of patients managed for CD or ITB at Asan Medical Center, a tertiary referral hospital, Seoul, Korea between 1996 and 2014. The temporal trends in the misdiagnosis rates between the two diseases were analyzed. The demographic and clinical characteristics were compared between CD patients who were initially misdiagnosed as ITB(final CD group) and vice versa(final ITB group). Final diagnostic criteria for ITB and medication for CD before definite diagnosis of TB were also analyzed in final ITB group.RESULTS In total, 2760 patients were managed for CD and 772 patients for ITB between 1996 and 2014. As well, 494 of the 2760 CD patients(17.9%) were initially misdiagnosed as ITB and 83 of the 772 ITB patients(10.8%) as CD. The temporal trend in misdiagnosing CD as ITB showed a decrease(OR = 0.89, 95%CI: 0.87-0.91, P < 0.001), whereas the temporal trend in misdiagnosing ITB as CD showed an increase(OR = 1.06, 95%CI: 1.01-1.11, P = 0.013). Age at diagnosis, presenting symptoms, and proportion of patients with active/past perianal fistula and active/inactive pulmonary tuberculosis(TB) were significantly different between final CD group and final ITB group. Forty patients(48.2%) in final ITB group were diagnosed by favorable response to empirical anti-TB treatment. Seventeen patients(20.5%) in final ITB group had inappropriately received corticosteroids and/or thiopurines due to misdiagnosis as CD. However, there were no mortalities in both groups. CONCLUSION Cases of CD misdiagnosed as ITB have been decreasing, whereas cases of ITB misdiagnosed as CD have been increasing over the past two decades.Hyungil Seo Seohyun Lee Hoonsub So Donghoi Kim Seon-Ok Kim Jae Seung Soh Jung Ho Bae Sun-Ho Lee Sung Wook Hwang Sang Hyoung Park Dong-Hoon Yang Kyung-Jo Kim Jeong-Sik Byeon Seung-Jae Myung Suk-Kyun Yang Byong Duk Ye 2017World Journal of Gastroenterology2017,23,34:3
12A case of Clostridium difficile infection complicated by acute respiratory distress syndrome treated with fecal microbiota transplantation显示文摘Acute respiratory distress syndrome is a life-threatening disorder caused mainly by pneumonia.Clostridium difficile infection(CDI)is a common nosocomial diarrheal disease.Disruption of normal intestinal flora by antibiotics is the main risk factor for CDI.The use of broadspectrum antibiotics for serious medical conditions can make it difficult to treat CDI complicated by acute respiratory distress syndrome.Fecal microbiota transplantation is a highly effective treatment in patients with refractory CDI.Here we report on a patient with refractory CDI and acute respiratory distress syndrome caused by pneumonia who was treated with fecal microbiota transplantation.Ji Eun Kim Tae-Geun Gweon Chang Dong Yeo Young-Seok Cho Gi Jun Kim Jae Young Kim Jong Wook Kim Hyunho Kim Hye Won Lee Taeseok Lim Hyoju Ham Hyun Jin Oh Yeongbok Lee Jaeho Byeon Sung Soo Park 2014World Journal of Gastroenterology2014,20,35:3
13Analysis on sports and recreation activity-related eye injuries presenting to the Emergency Department显示文摘AIM:To investigate the incidence and general characteristics of sports-related eye injuries in patients visiting the Emergency Department. METHODS: A cross-sectional,multi-center,observational study.Patients with an injured eye who visited the Emergency Department at one of nine hospitals in Korea were enrolled.All data were prospectively collected between March and September 2010 using a questionnaire.Eye injuries that occurred during risky sports were examined by gender and age.Additionally,the rate of open globe injuries that occurred with and without protective eyewear was examined for each activity.Continuous variables were compared using Student's t-test and categorical variables were compared using Chi-square test.RESULTS: A total of 446 patients had sports-related eye injuries.Teenagers(10-19 years old) and young adults(20-29 years old) had the most eye injuries.Eye injuries accounted for 0.2% of Emergency Department patients.Baseball was the most common cause of sports-related eye injuries,followed by soccer and hiking.Protective gear was worn by 9.4% of all patients.Patients that were 30-39 years of age had the highest rate of protective gear use,followed by patients that were 40-49 years of age.The proportion of sports-related eye injuries that were open-globe injuries was highest for soccer and hiking.CONCLUSION: Although injuries were most common in patients below the age of 10 years,these patients had the lowest rate of protective eyewear use.Injuries in adults over 40 years of age most commonly occurred during hiking,but the rate of protective eyewear use was low.Young athletes should be educated on and provided with protective eyewear and policies protective gear use should be established.For older adults,eye protection should be encouraged,especially during hiking.Sungbae Moon Hyun Wook Ryoo Jae Yun Ahn Jung Bae Park Kang Suk Seo Sang Do Shin Kyoung Jun Song Kang Hyun Lee In Sool Yoo Jin Seong Cho Hyun Ho Ryu Tae Oh Jeong Seok Ran Yeom Young Taek Kim Sung Ok Hong 2016International Journal of Ophthalmology(English edition)2016,9,10:3
14Retreatment with peginterferon and ribavirin in chronic hepatitis C显示文摘The development of boceprevir and telaprevir was a major step forward in the treatment of chronic hepatitis C.In addition,the treatment of these infections has been recently revolutionized by the approval of sofosbuvir and simeprevir.However,there are several challenges associated with the application of noveldrugs,such as new and more frequent adverse events,new drug interactions,and excessively high treatment costs.An additional concern is viral resistance.These considerations highlight the fact that direct-acting antiviral agents are not a panacea and may not be the best option for all patients who are in need of therapy.This retrospective study revealed that the sustained virologic response was not significantly reduced following peginterferon and ribavirin retreatment compared with the new therapy.We suggest that patients who experience relapse shortly after completing treatment with peginterferon and ribavirin have a reasonable chance of achieving a sustained virologic response when retreated with these drugs alone.Yong Min Jo Sung Wook Lee Sang Young Han Yang Hyun Baek Soo Young Kim Woo Jae Kim Ji Hye Ahn Ji Young Lee 2015World Journal of Gastroenterology2015,21,6:3

17Acquisition of pluripotency in the chick embryo occurs during intrauterine embryonic development via a unique transcriptional network显示文摘Background: Acquisition of pluripotency by transcriptional regulatory factors is an initial developmental event that is required for regulation of cell fate and lineage specification during early embryonic development. The evolutionarily conserved core transcriptional factors regulating the pluripotency network in fishes, amphibians, and mammals have been elucidated. There are also species-specific maternally inherited transcriptional factors and their intricate transcriptional networks important in the acquisition of pluripotency. In avian species, however, the core transcriptional network that governs the acquisition of pluripotency during early embryonic development is not well understood.Results: We found that chicken NANOG(c NANOG) was expressed in the stages between the pre-ovulatory follicle and oocyte and was continuously detected in Eyal-Giladi and Kochav stage I(EGK.I) to X. However, c POUV was not expressed during fol iculogenesis, but began to be detectable between EGK.V and VI. Unexpectedly, c SOX2 could not be detected during fol iculogenesis and intrauterine embryonic development. Instead of c SOX2, c SOX3 was maternally inherited and continuously expressed during chicken intrauterine development. In addition, we found that the pluripotency-related genes such as c ENS-1, c KIT, c LIN28 A, c MYC, c PRDM14, and c SALL4 began to be dramatical y upregulated between EGK.VI and VII.Conclusion: These results suggest that chickens have a unique pluripotent circuitry since maternally inherited c NANOG and c SOX3 may play an important role in the initial acquisition of pluripotency. Moreover, the acquisition of pluripotency in chicken embryos occurs at around EGK.VI to VI I.Jae Yong Han Hyo Gun Lee Young Hyun Park Young Sun Hwang Sang Kyung Kim Deivendran Rengaraj Byung Wook Cho Jeong Mook Lim 2018Journal of Animal Science and Biotechnology2018,9,3:2
18Preoperative serum carbohydrate antigen 19-9 levels predict early recurrence after the resection of early-stage pancreatic ductal adenocarcinoma显示文摘BACKGROUND Pancreatic ductal adenocarcinoma(PDAC)is a serious disease with a poor prognosis.Only a minority of patients undergo surgery due to the advanced stage of the disease,and patients with early-stage disease,who are expected to have a better prognosis,often experience recurrence.Thus,it is important to identify the risk factors for early recurrence and to develop an adequate treatment plan.AIM To evaluate the predictive factors associated with the early recurrence of earlystage PDAC.METHODS This study enrolled 407 patients with stage I PDAC undergoing upfront surgical resection between January 2000 and April 2016.Early recurrence was defined as a diagnosis of recurrence within 6 mo of surgery.The optimal cutoff values were determined by receiver operating characteristic(ROC)analyses.Univariate and multivariate analyses were performed to identify the risk factors for early recurrence.RESULTS Of the 407 patients,98 patients(24.1%)experienced early disease recurrence:26(26.5%)local and 72(73.5%)distant sites.In total,253(62.2%)patients received adjuvant chemotherapy.On ROC curve analysis,the optimal cutoff values for early recurrence were 70 U/mL and 2.85 cm for carbohydrate antigen 19-9(CA 19-9)levels and tumor size,respectively.Of the 181 patients with CA 19-9 level>70 U/mL,59(32.6%)had early recurrence,compared to 39(17.4%)of 226 patients with CA 19-9 level≤70 U/mL(P<0.001).Multivariate analysis revealed that CA 19-9 level>70 U/mL(P=0.006),tumor size>2.85 cm(P=0.004),poor differentiation(P=0.008),and non-adjuvant chemotherapy(P=0.025)were significant risk factors for early recurrence in early-stage PDAC.CONCLUSION Elevated CA 19-9 level(cutoff value>70 U/mL)can be a reliable predictive factor for early recurrence in early-stage PDAC.As adjuvant chemotherapy can prevent early recurrence,it should be recommended for patients susceptible to early recurrence.Sarang Hong Ki Byung Song Dae Wook Hwang Jae Hoon Lee Woohyung Lee Eunsung Jun Jaewoo Kwon Yejong Park Seo Young Park Naru Kim Dakyum Shin Hyeyeon Kim Minkyu Sung Yunbeom Ryu Song Cheol Kim 2021World Journal of Gastrointestinal Surgery2021,13,11:2
