| 1 | Limited endoscopic sphincterotomy plus large balloon dilation for choledocholithiasis with periampullary diverticula显示文摘AIM: To investigate the effectiveness and safety of limited endoscopic sphincterotomy (EST) plus large balloon dilation (LBD) for removing choledocholithiasis in patients with periampullary diverticula (PAD). METHODS: A total of 139 patients with common bile duct (CBD) stones were treated with LBD (10-20 mm balloon diameter) after limited EST. Of this total, 73 patients had PAD and 66 patients did not have PAD (controls). The results of stone removal and complications were retrospectively evaluated. RESULTS: There were no significant differences between the PAD and the control groups in overall successful stone removal (94.5% vs 93.9%), stone removal in first session (69.9% vs 81.8%), mechanical lithotripsy (12.3% vs 13.6%), and complications (11.0% vs 7.6%). Clinical outcomes were also similar between the types of PAD, but the rate of stone removal in first session and the number of sessions were significantly lower and more frequent, respectively, in type B PAD (papilla located near the diverticulum) than controls [23/38 (60.5%) vs 54/66 (81.8%), P = 0.021; and 1 (1-2) vs 1 (1-3), P = 0.037, respectively] and the frequency of pancreatitis was significantly higher in type A PAD (papilla located inside or in the margin of the diverticulum) than in controls (16.1% vs 3.0%, P = 0.047). CONCLUSION: Limited EST plus LBD was an effective and safe procedure for removing choledocholithiasis in patients with PAD. However, some types of PAD should be managed with caution. | Hyung Wook Kim Dae Hwan Kang Cheol Woong Choi Jong Hwan Park Jin Ho Lee Min Dae Kim Il Doo Kim Ki Tae Yoon Mong Cho Ung Bae Jeon Suk Kim Chang Won Kim Jun Woo Lee | 2010 | World Journal of Gastroenterology2010，16，34： | 26 |
| 2 | 柑桔黄龙病的可见-近红外光谱特征显示文摘柑桔黄龙病是一种以木虱为载体的细菌病原,目前还没有行之有效的治疗方法,对世界柑桔产业构成了严重的威胁。探索快速检测柑桔黄龙病的方法,对该病的诊断、评估及进一步的控制都具有重要意义。该研究采用了快速、无损的光谱方法对该病害特征进行初步探索。实验针对健康及染病植株的叶片及冠层,分别在实验室条件及田间环境下测量了其可见-近红外光谱反射率,以分析寻找二者的光谱差异。对原始光谱数据进行了平滑、聚类平均等预处理,并求取了一阶微分以确定其红边位置(red edge position,REP)。为了应对一阶微分在REP处的多个波峰现象,采用了线性外插值法及拉格朗日插值法量化REP。研究结果显示,健康及染病样本的反射率在可见光、近红外具有明显的差异。相比于健康样本,染病样本因其呈现的黄化现象,使其反射率在可见光区较高;又因黄龙病菌会明显阻碍叶片对水分的吸收而使其反射率在近红外较低。REP同样显示了潜在的区分能力,其明显随着染病程度的加深逐渐向红波段移动。在染病程度差异较大的数据集中,REP平均值相差达20nm;而在染病程度差异较小的数据集中,阈值分割法的分类精度也高达90%以上,且线性外插值法的分类精度略高于拉格朗日插值法。本研究成果为利用光谱技术快速无损检测柑桔黄龙病提供了可靠的理论依据。 | 李修华 李民赞 Won Suk Lee Reza Ehsani Ashish Ratn Mishra | 2014 | 光谱学与光谱分析2014，34，6： | 20 |
| 3 | Mitochondria-targeting drug conjugates for cytotoxic, anti-oxidizing and sensing purposes:current strategies and future perspectives显示文摘mitochondrial-targeting moieties to anticancer drugs, antioxidants and sensor molecules. Among them, the most widely applied mitochondrial targeting moiety is triphenylphosphonium(TPP), which is a delocalized cationic lipid that readily accumulates and penetrates through the mitochondrial membrane due to the highly negative mitochondrial membrane potential. Other moieties, including short peptides,dequalinium, guanidine, rhodamine, and F16, are also known to be promising mitochondrial targeting agents. Direct conjugation of mitochondrial targeting moieties to anticancer drugs, antioxidants and sensors results in increased cytotoxicity, anti-oxidizing activity and sensing activity, respectively,compared with their non-targeting counterparts, especially in drug-resistant cells. Although many mitochondria-targeted anticancer drug conjugates have been investigated in vitro and in vivo, further clinical studies are still needed. On the other hand, several mitochondria-targeting antioxidants have been analyzed in clinical phases I, II and III trials, and one conjugate has been approved for treating eye disease in Russia. There are numerous ongoing studies of mitochondria-targeted sensors. | Gantumur Battogtokh Yeon Su Choi Dong Seop Kang Sang Jun Park Min Suk Shim Kang Moo Huh Yong-Yeon Cho Joo Young Lee Hye Suk Lee Han Chang Kang | 2018 | Acta Pharmaceutica Sinica B2018，8，6： | 17 |

| 5 | Safety and efficacy of tenofovir in chronic hepatitis B-related decompensated cirrhosis显示文摘AIM To evaluate the safety and efficacy of tenofovir disoproxil fumarate(TDF) as a first-line therapy in decompensated liver disease. METHODS We enrolled 174 chronic hepatitis B-related liver cirrhosis patients treated with 300 mg/d TDF at six Korean centers. Of the 174 cirrhosis patients, 57 were assigned to the decompensated cirrhosis group and 117 were assigned to the compensated cirrhosis group. We followed the patients for 12 mo and evaluated clinical outcomes, including biochemical, virological, and serological responses. We also evaluated changes in hepatic and renal function and compared the decompensated and compensated cirrhosis groups. RESULTS The 1-year complete virological response(CVR) and Hepatitis B e antigen(HBe Ag) seroconversion were seen in 70.2% and 14.2% in the decompensated cirrhosis group, respectively. The rates of HBe Ag seroconversion/loss and ALT normalization at month 12 were similar in both groups. TDF treatment was also effective for decreasing the level of hepatitis B virus(HBV) DNA in both groups, but CVR was higher in the compensated group(88.9% vs 70.2%, P = 0.005). Tenofovir treatment for 12 mo resulted in improved Child-Turcotte-Pugh(CTP) and model for end-stage liver disease(MELD) scores in decompensated group(P < 0.001). Of the 57 decompensated patients, 39(68.4%) achieved CTP class A and 27(49.1%) showed improvement in the CTP score of 2 points after 12 mo of TDF. The observed rate of confirmed 0.5 mg/d L increases in serum levels of creatinine in the decompensated and compensated cirrhosis group were 7.0% and 2.5%, respectively(P < 1.000).CONCLUSION TDF therapy in decompensated cirrhosis patients was effective for decreasing HBV DNA levels and improving hepatic function with relatively lower CVR than in compensated cirrhosis. Thus, physicians should carefully monitor not only renal function but also treatment responses when using TDF in decompensated cirrhosis patients. | Soon Kyu Lee Myeong Jun Song Seok Hyun Kim Byung Seok Lee Tae Hee Lee Young Woo Kang Suk Bae Kim Il Han Song Hee Bok Chae Soon Young Ko Jae Dong Lee | 2017 | World Journal of Gastroenterology2017，23，13： | 14 |
| 6 | 基于Vis-NIR光谱的柑橘叶片黄龙病检测及其光谱特性研究显示文摘黄龙病作为柑橘类水果最具毁灭性的疾病之一,目前尚无有效的治愈手段,因此疾病预防成为已知的唯一有效方法。基于四种柑橘叶片(健康叶片、黄龙病叶片、铁缺乏叶片及氮缺乏叶片)VIS-NIR的反射光谱详细讨论了黄龙病的辨别方法以及在判别模型中光谱特征值的提取方法。在两类判别分析的特征值提取方法中,判别值(discriminability)运算的引入,为特征值提取提供了一个可靠依据,判别值越大表明光谱差异性越大。以被选特征值建立的Fisher线性判别分析模型,黄龙病与健康、铁缺乏、氮缺乏叶片的分类判别预测准确率分别都超过了90%,分类效果符合预期。最后,又讨论了分类树(classificationTree)在多类判别中的应用。通过对柑橘叶片原始反射谱,一阶导数谱及被选特征值分别建立分类模型,四种柑橘叶片平均预测准确度都超过88%,尤其是基于特征值的分类结果更是超过94%,验证了在多类判别中检测柑橘黄龙病的可行性及特征值提取的重要性。结合传统分类方法(k-NN,Bayesian)的结果分析,特征值作为输入变量的分类结果明显要优于原始光谱,证实了特征值选取的正确性,并为将来基于光谱特征值开发多光谱成像技术检测黄龙病打下坚实的基础。 | 马淏 吉海彦 Won Suk Lee | 2014 | 光谱学与光谱分析2014，34，10： | 12 |
| 7 | Gastric leptomeningeal carcinomatosis: Multi-center retrospective analysis of 54 cases显示文摘AIM: To identify the clinical features and outcomes of infrequently reported leptomeningeal carcinomatosis (LMC) of gastric cancer.METHODS: We analyzed 54 cases of cytologically confirmed gastric LMC at four institutions from 1994 to 2007.RESULTS: The male-to-female ratio was 32:22, and the patients ranged in age from 28 to 78 years (median,48.5 years). The majority of patients had advanced disease at initial diagnosis of gastric cancer. The clini-cal or pathologic tumor, node and metastasis stage ofthe primary gastric cancer wasin 38 patients (70%).The median interval from diagnosis of the primarymalignancy to the diagnosis of LMC was 6.3 mo, rang-ing between 0 and 73.1 mo. Of the initial endoscopic f indings for the 45 available patients, 23 (51%) of the patients were Bormann typeand 15 (33%) patientswere Bormann type. Pathologically, 94% of cases proved to be poorly differentiated adenocarcinomas. Signet ring cell component was also observed in 40% of patients. Headache (85%) and nausea/vomiting (58%) were the most common presenting symptoms of LMC. A gadolinium-enhanced magnetic resonance imaging was conducted in 51 patients. Leptomeningeal enhancement was noted in 45 cases (82%). Intrathecal (IT) chemotherapy was administered to 36 patients-primarily methotrexate alone (61%), but also in combi-nation with hydrocortisone/± Ara-C (39%). The median number of IT treatments was 7 (range, 1-18). Concomitant radiotherapy was administered to 18 patients, and concomitant chemotherapy to seven patients. Sev-enteen patients (46%) achieved cytological negative conversion. Median overall survival duration from the diagnosis of LMC was 6.7 wk (95% CI: 4.3-9.1 wk). In the univariate analysis of survival duration, hemoglobin, IT chemotherapy, and cytological negative conversion showed superior survival duration (P = 0.038, P = 0.010, and P = 0.002, respectively). However, in our multivariate analysis, only cytological negative conversion was predictive of relatively longer survival duration (3.6, 6.7 and 14.6 wk, P = 0.030, RR: 0.415, 95% CI: 0.188-0.918).CONCLUSION: Although these patients had a fatal clinical course, cytologic negative conversion by IT chemotherapy may improve survival. | Sung Yong Oh Su-Jin Lee Jeeyun Lee Suee Lee Sung-Hyun Kim Hyuk-Chan Kwon Gyeong-Won Lee Jung Hun Kang In Gyu Hwang Joung-Soon Jang Ho Yeong Lim Young Suk Park Won Ki Kang Hyo-Jin Kim | 2009 | World Journal of Gastroenterology2009，15，40： | 10 |

| 9 | Surgical outcome of pancreatic cancer using radical antegrade modular pancreatosplenectomy procedure显示文摘AIM:To evaluate the surgical outcomes following radical antegrade modular pancreatosplenectomy (RAMPS) for pancreatic cancer. METHODS:Twenty-four patients underwent RAMPS with curative intent between January 2005 and June 2009 at the National Cancer Center, South Korea. Clinicopathologic data, including age, sex, operative findings, pathologic results, adjuvant therapy, postop-erative clinical course and follow-up data were retro-spectively collected and analyzed for this study. RESULTS:Twenty-one patients (87.5%) underwent distal pancreatectomy and 3 patients (12.5%) underwent total pancreatectomy using RAMPS. Nine patients (37.5%) underwent combined vessel resection, including 8 superior mesenteric-portal vein resections and 1 celiac axis resection. Two patients (8.3%) underwent combined resection of other organs, including the colon, stomach or duodenum. Negative tangential margins were achieved in 22 patients (91.7%). The mean tumor diameter for all patients was 4.09 ± 2.15 cm. The 2 patients with positive margins had a mean diameter of 7.25 cm. The mean number of retrieved lymph nodes was 20.92 ± 11.24 and the node positivity rate was 70.8%. The median survival of the 24 patients was 18.23 ± 6.02 mo. Patients with negative margins had a median survival of 21.80 ± 5.30 mo and those with positive margins had a median survival of 6.47 mo (P = 0.021). Nine patients (37.5%) had postoperative complications, but there were no postoperative mortalities. Pancreatic fistula occurred in 4 patients (16.7%):2 patients had a grade A fistula and 2 had a grade B fistula. On univariate analysis, histologic grade, positive tangential margin, pancreatic fistula and adjuvant therapy were significant prognostic factors for survival. CONCLUSION:RAMPS is a feasible procedure for achieving negative tangential margins in patients with carcinoma of the body and tail of the pancreas. | Ye Rim Chang Sung-Sik Han Sang-Jae Park Seung Duk Lee Tae Suk Yoo Young-Kyu Kim Tae Hyun Kim Sang Myung Woo Woo Jin Lee Eun Kyung Hong | 2012 | World Journal of Gastroenterology2012，18，39： | 9 |
| 10 | Prediction of liver cirrhosis, using diagnostic imaging tools显示文摘Early diagnosis of liver cirrhosis is important. Ultrasoundguided liver biopsy is the gold standard for diagnosis of liver cirrhosis. However, its invasiveness and sampling bias limit the applicability of the method. Basic imaging for the diagnosis of liver cirrhosis has developed over the last few decades, enabling early detection of morphological changes of the liver by ultrasonography(US), computed tomography, and magnetic resonance imaging(MRI). They are also accurate diagnostic methods for advanced liver cirrhosis, for which early diagnosis is difficult. There are a number of ways to compensate for this difficulty, including texture analysis to more closely identify the homogeneity of hepatic parenchyma, elastography to measure the stiffness and elasticity of the liver, and perfusion studies to determine the blood flow volume, transit time, and velocity. Amongst these methods, elastography using US and MRI was found to be slightly easier, faster, and able to provide an accurate diagnosis. Early diagnosis of liver cirrhosis using MRI or US elastography is therefore a realistic alternative, but further research is still needed. | Suk Keu Yeom Chang Hee Lee Sang Hoon Cha Cheol Min Park | 2015 | World Journal of Hepatology2015，7，17： | 9 |
| 11 | Comparison of postpolypectomy bleeding between epinephrine and saline submucosal injection for large colon polyps by conventional polypectomy:A prospective randomized,multicenter study显示文摘AIM:To evaluate and compare the clinical outcomes of prophylactic submucosal saline-epinephrine injection and saline injection alone for large colon polyps by conventional polypectomy. METHODS:A prospective study was conducted from July 2003 to July 2004 at 11 tertiary endoscopic centers. Large colon polyps (> 10 mm in diameter) wererandomized to undergo endoscopic polypectomy with submucosal saline-epinephrine injection (epinephrine group) or normal saline injection (saline group). Endoscopic polypectomy was performed by the conventional snare method,and early (< 12 h) and late bleeding complications (12 h-30 d) were observed. RESULTS:A total of 561 polyps in 486 patients were resected by endoscopic polypectomy. Overall,bleeding complications occurred in 7.6% (37/486) of the patients,including 4.9% (12/244) in the epinephrine group,and 10.3% (25/242) in the saline group. Early and late postpolypectomy bleeding (PPB) occurred in 6.6% (32/486) and 1% (5/486) of the patients,respectively,including 4.5% (11/244),0.4% (1/244) in the epinephrine group,and 8.7% (21/242),1.7% (4/242) in the saline group. No significant differences in the rates of overall,early and late PPB were observed between the 2 groups. Multivariate stepwise logistic regression analysis revealed that large size (> 2 cm) and neoplastic polyps were independently and significantly associated with the presence of PPB. CONCLUSION:The prophylactic submucosal injection of diluted epinephrine does not appear to provide an additional advantage over the saline injection alone for the prevention of PPB. | Suck-Ho Lee Il-Kwun Chung Sun-Joo Kim Jin-Oh Kim Bong-Min Ko Won-Ho Kim Hyun-Soo Kim Dong-IL Park Hyo-Jong Kim Jeong-Sik Byeon Suk-Kyun Yang Byeong Ik Jang Sung-Ae Jung Yoon-Tae Jeen Jai-Hyun Choi Hwang Choi Dong-Soo Han Jae Suk Song | 2007 | World Journal of Gastroenterology2007，13，21： | 9 |
| 12 | 小波变换与分水岭算法融合的番茄冠层叶片图像分割显示文摘在基于机器视觉的作物营养诊断研究中,通常需要采集叶片样本并在实验室条件下定量测定其营养素含量,但由于叶片间相互重叠,往往使得叶片样本不能清晰地反映在群体番茄冠层图像中。为了解决这一问题,需要利用图像分析技术有效提取作物冠层图像中的叶片,并根据处理结果采集实验室测定样本。本文从复杂背景剔除、梯度图计算、小波变换、标记选取、分水岭分割等环节出发,实现了基于小波变换与分水岭算法融合的番茄冠层多光谱图像叶片分割。首先对比了4种复杂背景剔除算法,发现当增强因子a=1.3时,基于归一化植被指数(Normalized difference vegetation index,NDVI)的阈值分割目标提取准确,适合各种光照条件,时空复杂度低。其次在梯度图计算方面,近红外(Near infrared,NIR)波段图像形态学梯度在保持目标边缘的同时,能消除大量由叶脉、光照等引起的叶片内纹理细节。然后以小波分析为基础进行标记选取,发现当选取db4小波函数、4层小波分解低频系数、阈值为18的H-maxima变换能得到最优的目标标记结果。最后对多光谱番茄冠层图像的小波变换分水岭分割和数学形态学分水岭分割结果进行叠加,发现对复杂背景及不同光照强度下的番茄冠层叶片平均误分率为21%,为基于多光谱图像分析的番茄叶片营养素含量检测提供了一定的技术支持。 | 丁永军 张晶晶 LEE Won Suk 李民赞 | 2017 | 农业机械学报2017，48，9： | 9 |
| 13 | Randomized controlled trial of sodium phosphate tablets vs polyethylene glycol solution for colonoscopy bowel cleansing显示文摘AIM:To compare efficacy,patient compliance,acceptability,satisfaction,safety,and adenoma detection rate of sodium phosphate tablets(NaP,CLICOLONTM)to a standard 4 L polyethylene glycol(PEG)solution for bowel cleansing for adults undergoing colonoscopy.METHODS:In this multicenter,randomized,prospective,investigator-blind study,the relatively young(19-60years)healthy outpatients without comorbidity were randomly assigned to one of two arms.All colonoscopy were scheduled in the morning.The NaP group was asked to take 4 tablets,5 times the evening before and4 tablets,3 times early on the morning of the colonoscopy.The PEG group was asked to ingest 2 L of solution the evening before and 2 L early in the morning of the procedure.Adequacy of bowel preparation was scored using the Boston bowel preparation scale.RESULTS:No significant differences were observed between the NaP group(n=158)and PEG group(n=162)in bowel cleansing quality(adequate preparation93.0%vs 92.6%,P=0.877),patient compliance(P=0.228),overall adverse events(63.3%vs 69.1%,P=0.269),or adenoma detection rate(34.8%vs 35.2%,P=0.944).Patient acceptability,satisfaction,and patient rating of taste were higher in the NaP group than in the PEG group(P<0.001).CONCLUSION:NaP tablets,compared with PEG solution,produced equivalent colon cleansing,did not cause more side effects,and had better patient acceptability and satisfaction in the relatively young(age<60years)healthy individuals without comorbidity.An oral tablet formulation could make bowel preparation less burdensome,resulting in greater patient participation in screening programs. | Yoon Suk Jung Chang Kyun Lee Hyo Jong Kim Chang Soo Eun Dong Soo Han Dong Ⅱ Park | 2014 | World Journal of Gastroenterology2014，20，42： | 9 |
| 14 | Risk factors for local recurrence after en bloc endoscopic submucosal dissection for early gastric cancer显示文摘AIM: To investigate factors related to recurrence following en bloc resection using endoscopic submucosal dissection(ESD) in patients with early gastric cancer(EGC). METHODS: A total of 1121 patients(1215 lesions) who had undergone ESD for gastric neoplasia between April 2003 and May 2010 were retrospectively reviewed. Data from 401 patients(415 lesions) were analyzed, following the exclusion of those who underwent piecemeal resection, with deep resection margin invasion or lateral margin infiltration, and diagnosed with benign lesions. RESULTS: Local recurrence after en bloc ESD was found in 36 cases(8.7%). Unclear resection margins, long procedure times, and narrow safety margins were identified as risk factors for recurrence. Lesions located in the upper third of the stomach showed a higher rate of recurrence than those located in the lower third of the stomach(OR = 2.9, P = 0.03). The probability of no recurrence for up to 24 mo was 79.9% in those with a safety resection margin ≤ 1 mm and 89.5% in those with a margin > 1 mm(log-rank test, P = 0.03). CONCLUSION: Even in cases in which en bloc ESD is performed for EGC, local recurrence still occurs. To reduce local recurrences, more careful assessment will be needed prior to the implementation of ESD in casesin which the tumor is located in the upper third of the stomach. In addition, clear identification of tumor boundaries as well as the securing of sufficient safety resection margins will be important. | Ju Yup Lee Kwang Bum Cho Eun Soo Kim Kyung Sik Park Yoo Jin Lee Yoon Suk Lee Byoung Kuk Jang Woo Jin Chung Jae Seok Hwang | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，7： | 8 |
| 15 | Diffusion-weighted imaging of biliopancreatic disorders:Correlation with conventional magnetic resonance imaging显示文摘Diffusion-weighted magnetic resonance imaging(DWI)is a well established method for the evaluation of intracranial diseases,such as acute stroke.DWI for extracranial application is more difficult due to physiological motion artifacts and the heterogeneous composition of the organs.However,thanks to the newer technical development of DWI,DWI has become increasingly used over the past few years in extracranial organs including the abdomen and pelvis.Most previous studies of DWI have been limited to the evaluation of diffuse parenchymal abnormalities and focal lesions in abdominal organs,whereas there are few studies about DWI for the evaluation of the biliopancreatic tract.Although further studies are needed to determine its performance in evaluating bile duct,gallbladder and pancreas diseases,DWI has potential in the assessment of the functional information on the biliopancreatic tract concerning the status of tissue cellularity,because increased cellularity is associated with impeded diffusion,as indicated by a reduction in the apparent diffusion coefficient.The detection of malignant lesions and their differentiation from benign tumor-like lesions in the biliopancreatic tract could be improved using DWI in conjunction with findings obtained with conventional magnetic resonance cholagiopancreatography.Additionally,DWI can be useful for the assessment of the biliopancreatic tract in patients with renal impairment because contrast-enhanced computed tomography or magnetic resonance scans should be avoided in these patients. | Nam Kyung Lee Suk Kim Gwang Ha Kim Dong Uk Kim Hyung Il Seo Tae Un Kim Dae Hwan Kang Ho Jin Jang | 2012 | World Journal of Gastroenterology2012，18，31： | 8 |

Only 8 cases have been reported in the literature. Concurrent occurrence of HCC and NEC in the liver is classified as combined type or collision type by histological distributional patterns; only 2 cases have been reported. Herein, we report a case of collision type concurrent occurrence of HCC and NEC, in which primary hepatic NEC was in only a small portion of the nodule, which is different from the 2 previously reported cases. A 72-year-old male with chronic hepatitis C was admitted to our hospital for a hepatic mass detected by liver computed tomography(CT) at another clinic. Because the nodule was in hepatic segment 3 and had proper radiologic findings for diagnosis of HCC, including enhancement in the arterial phase and wash-out in the portal and delay phases, the patient was treated with laparoscopic left lateral sectionectomy. The pathology demonstrated that the nodule was 2.5 cm and was moderately differentiated HCC. However, a 3 mm-sized focal neuroendocrine carcinoma was also detected on the capsule of the nodule. The tumor was concluded to be a collision type with HCC and primary hepatic NEC. After the surgery, for follow-up, the patient underwent a liver CT every 3 mo. Five multiple nodules were found in the right hepatic lobe on the follow-up liver CT 6 mo post-operatively. As the features of the nodules in the liver CT and MRI were different from that of HCC, a liver biopsy was performed. Intrahepatic recurrent NEC was proven after the liver biopsy, which showed the same pathologic features with the specimen obtained 6 mo ago. Palliative chemotherapy with a combination of etoposide and cisplatin has been administered for 4 months, showing partial response. | Gyu Ho Choi Sun Young Ann Soon Il Lee Suk BaeKim Il Han Song | 2016 | World Journal of Gastroenterology2016，22，41： | 8 |
