| 1 | Catheter tract implantation metastases associated with percutaneous biliary drainage for extrahepatic cholangiocarcinoma显示文摘AIM: To estimate the incidence of catheter tract implantation metastasis among patients undergoing percutaneous transhepatic biliary drainage (PTBD) for extrahepatic cholangiocarcinoma, and to provide data regarding the management of this unusual complication of PTBD by reviewing cases reported in the literature.METHODS: A retrospective analysis of 67 consecutive patients who underwent PTBD before the resection of extrahepatic cholangiocarcinoma was conducted. The median follow-up period after PTBD was 106 mo. The English language literature (PubMed, National Library of Medicine, Bethesda, MD, USA), from January 1966through December 2004, was reviewed.RESULTS: Catheter tract implantation metastasis developed in three patients. The cumulative incidence of implantation metastasis reached a plateau (6%)at 20 mo after PTBD. All of the three patients with implantation metastasis died of tumor progression at 3, 9, and 20 mo after the detection of this complication. Among the 10 reported patients with catheter tract implantation metastasis from extrahepatic cholangiocarcinoma (including our three patients), two survived for more than 5 years after the excision of isolated catheter tract metastases.CONCLUSION: Catheter tract implantation metastasis is not a rare complication following PTBD for extrahepatic cholangiocarcinoma. Although the prognosis for patients with this complication is generally poor, the excision of the catheter tract may enable survival in selected patients with isolated metastases along the catheter tract. | Jun Sakata Yoshio Shirai Toshifumi Wakai Tatsuya Nomura Eiko Sakata Katsuyoshi Hatakeyama | 2005 | World Journal of Gastroenterology2005，11，44： | 31 |
| 2 | Pancreatic neuroendocrine tumor and solid-pseudopapillary neoplasm: Key immunohistochemical profiles for differential diagnosis显示文摘AIM To reveal better diagnostic markers for differentiating neuroendocrine tumor(NET) from solid-pseudopapillary neoplasm(SPN), focusing primarily on immunohistochemical analysis.METHODS We reviewed 30 pancreatic surgical specimens of NET(24 cases) and SPN(6 cases). We carried out comprehensive immunohistochemical profiling using 9 markers: Synaptophysin, chromogranin A, pancytokeratin, E-cadherin, progesterone receptor,vimentin, α-1-antitrypsin, CD10, and β-catenin.RESULTS E-cadherin staining in NETs, and nuclear labeling of β-catenin in SPNs were the most sensitive and specific markers. Dot-like staining of chromogranin A might indicate the possibility of SPNs rather than NETs. The other six markers were not useful because their expression overlapped widely between NETs and SPNs. Moreover, two cases that had been initially diagnosed as NETs on the basis of their morphological features, demonstrated SPN-like immunohistochemical profiles. Careful diagnosis is crucial as we actually found two confusing cases showing disagreement between the tumor morphology and immunohistochemical profiles.CONCLUSION E-cadherin, chromogranin A, and β-catenin were the most useful markers which should be employed for differentiating between NET and SPN. | Yusuke Ohara Tatsuya Oda Shinji Hashimoto Yoshimasa Akashi Ryoichi Miyamoto Tsuyoshi Enomoto Kaishi Satomi Yukio Morishita Nobuhiro Ohkohchi | 2016 | World Journal of Gastroenterology2016，22，38： | 19 |

| 4 | Cooperative function of antioxidant and redox systems against oxidative stress in male reproductive tissues显示文摘Reactive oxygen species (ROS) are produced under oxidative stress, such as high oxygen concentration and during the metabolic consumption of oxygen molecules. Male reproductive tissues appear to be continuously exposed to ROS produced by active metabolism. In addition, spermatozoa must pass through a high oxygen environ-ment during the mating process. Thus, to maintain viable reproductive ability, a protective mechanism against oxida-tive stress is of importance. Here, we overview our current understanding of the cooperative function of antioxidative and redox systems that are involved in male fertility. Superoxide dismutase and glutathione peroxidase are major enzymes that scavenge harmful ROS in male reproductive organs. In turn, glutathione and thioredoxin systems constitute the main redox systems that repair oxidized and damaged molecules and also play a role in regulating a variety of cellular functions. While glutathione functions as an antioxidant by donating electrons to glutathione peroxidase and thioredoxin donates electrons to peroxiredoxin as a counterpart of glutathione peroxidase. In addition,aldo-keto reductases, which detoxify carbonyl compounds produced by oxidative stress, are present at high levels in the epithelia of the genital tract and Sertoli cells of the testis. Since these systems are involved in cross-talk, a comprehensive understanding will be required to maintain the physiological functions of male reproductive system.( Asian J Andro12003 Sep; 5: 231-242) | Junichi Fujii Yoshihito Iuchi Shingo Matsuki Tatsuya Ishii | 2003 | Asian Journal of Andrology2003，5，3： | 19 |
| 5 | A combination treatment of entecavir and early-phase corticosteroid in severe exacerbation of chronic hepatitis B显示文摘Of patients with severe exacerbation of chronic hepatitis B accompanied by jaundice and coagulopathy,20%-30%have a fatal outcome.In this report,we describe 2 cases of severe exacerbation of chronic hepatitis B with jaundice and coagulopathy who were successfully treated with a combination of entecavir and corticosteroid.In both cases,rapid reductions in serum hepatitis B virus(HBV)-DNA levels were observed,and corticosteroid was stopped after serum HBV-DNA levels became undetectable.Entecavir treatment was continued.Generally,entecavir treatment reduced serum HBV-DNA levels rapidly,although the improvement in liver function was delayed by a few weeks.During this time lag,liver cell injury continued and the disease progressed.Corticosteroid suppressed the excessive host immune response and was useful for stopping progressive deterioration.A combination of entecavir and early-phase corticosteroid may be a useful treatment in severe exacerbation of chronic hepatitis B. | Kazuyuki Matsumoto Yasuhiro Miyake Hirokazu Miyatake Masahiro Takahara Takayuki Imada Satoru Yagi Tatsuya Toyokawa Morihito Nakatsu Masaharu Ando Mamoru Hirohata | 2009 | World Journal of Gastroenterology2009，15，13： | 16 |

| 8 | Recent Advances in Researches on Physiologically Active Substances in Holothurians显示文摘In this report, we reviewed recent literature on physiologically active substances from sea cucumbers (SCs) andtheir activities together with results obtained from our study. Preventive properties against lipid metabolism were reported inrats using a whole SC preparation with no particular constituent specified. Administration of the preparation lowered serumand hepatic cholesterol levels and improved the HDL/LDL ratio. These functions may be attributed to the stimulatory effectof the extract on the secretion of cholesterol in feces. Novel fucosylated chondroitin sulfates (FCSs) from Ludwigothureagrisea significantly induced fibroblast growth factor 2-dependent angiogenesis in human umbilical vein endothelial cells (HU-VECs). The proangiogenetic activity seemed attributable to the action of the sulfated fucose branches on the polysaccharide.SCs contain mycosporine-like amino acids (MAAs) that are capable of absorbing UV. A biogenetic precursor of MAAs wasfirst reported in SCs. The anti-proliferative effects of a branched chain fatty acid from a sea cucumber on prostate cancercells was reported with the activity of 5-lipoxygenase. Glycosphingolipid constituents in SCs have been systematically ana-lyzed over the past ten years. The results showed that the gangliosides in several SCs differed from those of mammals in thata sialic acid of SC gangliosides directly binded to glucose of cerebroside. Neuritogenic activity of the glycosphingolipids wasdemonstrated in vitro experiments and may lead to the development of therapeutic products for neurological disorders. Ourstudy also showed that sphingoid bases, the hydrolyzed products of glycosphingolipids from SCs, induced significant apoptosisin several tumor cell lines. | Hirata Takashi Zaima Nobuhiro Yamashita Kyoko Noguchi Ryoko XUE Changhu Sugawara Tatsuya | 2005 | Journal of Ocean University of China2005，4，3： | 14 |
| 9 | Gastric cancer arising from the remnant stomach after distal gastrectomy:A review显示文摘Gastric stump carcinoma was initially reported by Balfore in 1922,and many reports of this disease have since been published. We herein review previous reports of gastric stump carcinoma with respect to epidemiology,carcinogenesis,Helicobacter pylori(H. pylori) infection,Epstein-Barr virus infection,clinicopathologic characteristics and endoscopic treatment. In particular,it is noteworthy that no prognostic differences are observed between gastric stump carcinoma and primary upper third gastric cancer. In addition,endoscopic submucosal dissection has recently been used to treat gastric stump carcinoma in the early stage. In contrast,many issues concerning gastric stump carcinoma remain to be clarified,including molecular biological characteristics and the carcinogenesis of H.pylori infection.We herein review the previous pertinent literature and summarize the characteristics of gastric stump carcinoma reported to date. | Shinsuke Takeno Tatsuya Hashimoto Kenji Maki Ryosuke Shibata Hironari Shiwaku Ippei Yamana Risako Yamashita Yuichi Yamashita | 2014 | World Journal of Gastroenterology2014，20，38： | 13 |
| 10 | Role of bile acids in the regulation of the metabolic pathways显示文摘Recent studies have revealed that bile acids(BAs)are not only facilitators of dietary lipid absorption but also important signaling molecules exerting multiple physiological functions.Some major signaling pathways involving the nuclear BAs receptor farnesoid X receptor and the G protein-coupled BAs receptor TGR5/M-BAR have been identified to be the targets of BAs.BAs regulate their own homeostasis via signaling pathways.BAs also affect diverse metabolic pathways including glucose metabolism,lipid metabolism and energy expenditure.This paper suggests the mechanism of controlling metabolism via BA signaling and demonstrates that BA signaling is an attractive therapeutic target of the metabolic syndrome. | Hiroki Taoka Yoko Yokoyama Kohkichi Morimoto Naho Kitamura Tatsuya Tanigaki Yoko Takashina Kazuo Tsubota Mitsuhiro Watanabe | 2016 | World Journal of Diabetes2016，7，13： | 11 |
| 11 | Successful treatment of conversion chemotherapy for initially unresectable synchronous colorectal liver metastasis显示文摘A 72-year-old woman with a sigmoid colon cancer and a synchronous colorectal liver metastasis(CRLM),which involved the right hepatic vein(RHV)and the inferior vena cava(IVC),was referred to our hospital.The metastatic lesion was diagnosed as initially unresectable because of its invasion into the confluence of the RHV and IVC.After she had undergone laparoscopic sigmoidectomy for the original tumor,she consequently had 3 courses of modified 5-fluorouracil,leucovorin,and oxaliplatin(m FOLFOX6)plus cetuximab.Computed tomography revealed a partial response,and the confluence of the RHV and IVC got free from cancer invasion.After 3 additional courses of m FOLFOX6 plus cetuximab,preoperative percutaneous transhepatic portal vein embolization(PTPE)was performed to secure the future remnant liver volume.Finally,a right hemihepatectomy was performed.The postoperative course was uneventful.The patient was discharged from the hospital on postoperative day 13.She had neither local recurrence nor distant metastasis 18 mo after the last surgical intervention.This multidisciplinary strategy,consisting of conversion chemotherapy using FOLFOX plus cetuximab and PTPE,could contribute in facilitating curative hepatic resection for initially unresectable CRLM. | Kenta Baba Akihiko Oshita Mohei Kohyama Satoshi Inoue Yuta Kuroo Takuro Yamaguchi Hiroyuki Nakamura Yoichi Sugiyama Tatsuya Tazaki Masaru Sasaki Yuji Imamura Yutaka Daimaru Hideki Ohdan Atsushi Nakamitsu | 2015 | World Journal of Gastroenterology2015，21，6： | 10 |
| 12 | Acute appendicitis following endoscopic mucosal resection of cecal adenoma显示文摘Endoscopic mucosal resection(EMR) allows the removal of flat or sessile lesions, laterally spreading tumors, and carcinoma of the colon or the rectum limited to the mucosa or the superficial submucosa. Acute appendicitis is the most common abdominal emergency requiring emergency surgery, and it is also a rare complication of diagnostic colonoscopy and therapeutic endoscopy, including EMR. In the case presented here, a 53-year-old female underwent colonoscopy due to a positive fecal occult blood test and was diagnosed with cecal adenoma. She was referred to our hospital and admitted for treatment. The patient had no other symptoms. EMR was performed, and 7 h after the surgery, the patient experienced right-lower abdominal pain. Laboratory tests performed the following day revealed a WBC count of 16000/mm3, a neutrophil count of 14144/mm3, and a C-reactive protein level of 2.20 mg/d L, indicating an inflammatory response. Computed tomography also revealed appendiceal wall thickening and swelling, so acute appendicitis following EMR was diagnosed. Antibiotics were initiated leading to total resolution of the symptoms, and the patient was discharged on the sixth post-operative day. Pathological analysis revealed a high-grade cecal tubular adenoma. Such acute appendicitis following EMR is extremely rare, and EMR of the cecum may be a rare cause of acute appendicitis. | Yukako Nemoto Junya Tokuhisa Nagasato Shimada Tatsuya Gomi Iruru Maetani | 2015 | World Journal of Gastroenterology2015，21，27： | 9 |

| 14 | Cholangiopancreatography troubleshooting:the usefulness of endoscopic retrieval of migrated biliary and pancreatic stents显示文摘BACKGROUND:Stent migration in the hepatopancreatic duct might arise as one of the rare complications associated with biliary or pancreatic stenting.Although there are some procedures to retrieve the migrated stent,including surgical,percutaneous,and endoscopic approaches,endoscopy should be attempted first because it is least invasive.This study set out to evaluate the usefulness of endoscopic retrieval of migrated biliary and pancreatic stents.METHODS:Plastic stents that migrated in the bile duct(35 patients)or pancreatic duct(2)were retrieved with endoscopic retrograde cholangiopancreatography.Devices used were snare forceps,a basket catheter,grasping forceps,biopsy forceps,a balloon catheter,and the Soehendra stent retriever.RESULTS:Endoscopic retrieval of migrated stents was performed successfully in 36(97.0%)of the 37 patients.The devices utilized for successful treatment were basket catheter(13 patients),grasping forceps(10),snare forceps(8),balloon catheter(3),biopsy forceps(1),and the Soehendra stent retriever(1).The unsuccessfully treated patient with chronic pancreatitis underwent surgery since the guide wire did not move forward due to bile duct stenosis,and there was also duodenal stenosis.One patient developed mild pancreatitis after withdrawal of the stent;the pancreatitis was relieved with conservative treatment.CONCLUSIONS:Endoscopic retrieval of migrated biliary and pancreatic stents appears to be useful because of its safety and low invasiveness.However,various forceps should be prepared for the retrieval of a migrated stent. | Yuji Sakai Toshio Tsuyuguchi Takeshi Ishihara Harutoshi Sugiyama Reiko Eto Tatsuya Fujimoto Shin Yasui Ryo Tamura Seiko Togo Motohisa Tada Osamu Yokosuka | 2009 | Hepatobiliary & Pancreatic Diseases International2009，8，6： | 8 |
| 15 | Stratifying the risk of lymph node metastasis in undifferentiated-type early gastric cancer显示文摘AIM:To study how lymph node metastasis(LNM) risk is stratified in undifferentiated-type early gastric cancer(undiff-EGC) dependent on combinations of risk factors.METHODS:Five hundred and sixty-seven cases with undiff-EGC undergoing gastrectomy with lymphadenectomy were examined retrospectively.Using clinicopathological factors of patient age,location,size,an endoscopic macroscopic tumor form,ulceration,depth,histology,lymphatic involvement(LI) and venous involvement(VI),LNM risk was examined and stratified by conventional statistical analysis and datamining analysis.RESULTS:LNM was positive in 44 of 567 cases(7.8%).Univariate analysis revealed > 2 cm,protrusion,submucosal(sm),mixed type,LI and VI as significant prognostic factors and > 2 cm and LI-positive were independent factors by multivariate analysis.In preoperatively evaluable factors excluding LVI,sm and > 2 cm were independent factors.According to the depth and size,cases were categorized into the low-risk group [m and ≤ 2 cm,0%(LNM incidence)],the moderaterisk group(m and > 2 cm,5.6%; and sm and ≤ 2 cm,6.0%),and the high-risk group(sm and > 2 cm,19.3%).On the other hand,LNM occurred in 1.4% in all LI-negative cases,greatly lower than 28.2% in all LI-positive cases,and LNM incidence was low in LInegative cases even in the moderate- and high-risk groups.CONCLUSION:LNM-related factors in undiff-EGC were depth and size preoperatively while those were LI and size postoperatively.Among these factors,LI was the most significantly correlated factor. | Yukiko Asakawa Masahiko Ohtaka Shinya Maekawa Mitsuharu Fukasawa Yasuhiro Nakayama Tatsuya Yamaguchi Taisuke Inoue Tomoyoshi Uetake Minoru Sakamoto Tadashi Sato Yoshihiko Kawaguchi Hideki Fujii Kunio Mochizuki Masao Hada Toshio Oyama Tomotaka Yasumura Kosaku Omata Atsushi Nishiyama Keiichi Naito Hideo Hata Yoshiaki Haba Kazuyuki Miyata Haruhisa Saitoh Yoichi Yamadera Kazuo Miura Akira Kawaoi Tohru Abe Hajime Tsunoda Yuji Honda Masayuki Kurosaki Nobuyuki Enomoto | 2015 | World Journal of Gastroenterology2015，21，9： | 8 |
| 16 | A case of hepatic angiomyolipoma difficult to distinguish from hepatocellular carcinoma显示文摘We report a case of hepatic angiomyolipoma with uncommon clinical features. A 56-year-old man presented with a hepatic tumor in the caudate lobe. The tumor was hypoechoic on ultrasonography, showed early-phase hyperattenuation on enhanced computed tomography and did not absorb iron on superparamagnetic iron oxide-enhanced magnetic resonance imaging. Hepatocellular carcinoma was highly suspected, and the patient underwent hepatic resection. Histologically, the tumor was mainly composed of smooth muscle cells and contained small amounts of adipose cells and blood vessels. On immunohistochemical staining, the smooth muscle cells were positive for a melanocytic cell-specific monoclonal antibody. In cases with uncommon features of angiomyolipoma, it is quite difficult to distinguish angiomyolipoma from hepatocellular carcinoma. | Masahiro Takahara Yasuhiro Miyake Kazuyuki Matsumoto Daisuke Kawai Eisuke Kaji Tatsuya Toyokawa Morihito Nakatsu Masaharu Ando Mamoru Hirohata | 2009 | World Journal of Gastroenterology2009，15，23： | 8 |
| 17 | Irrigation system and land use effect on surface water quality in river, at lake Dianchi, Yunnan, China显示文摘The surface water samples were collected in river Dahe and its tributaries,which flow into severely eutrophic lake Dianchi,Yunnan Province,China,in order to elucidate factors controlling water quality fluctuations.The temporal and spatial distribution of water quality tendency was observed.The water quality of each river is dependent on the hydrology effect such water gate and circulating irrigation system.We must consider the hydrology effect to accurately understand water quality variations of river in this study field.In river without highly circulating irrigation system or water gate effect,the downstream nitrate nitrogen(NO3-N) concentration increase occurred in area dominated by open field cultivation,whereas the NO3-N concentration was constant or decreased in area dominated by greenhouse land use.This result suggests that greenhouse covers the soil from precipitation,and nitrate load of greenhouse could be less than that of open field cultivation while the rainfall event.In the upper reaches of river,where is dominated by open field cultivation,there were no sharp increase dissolved molybdate reactive phosphorus and total phosphorus concentration,but P load was accumulated in the lower reaches of river,whose predominant land use is greenhouse.Although the P sources is unclear in this study,greenhouse area may have potential of P loads due to its high P content in greenhouse soil.Considering hydrology effect is necessary to determine what the major factor is influencing the water quality variation,especially in area with highly complicated irrigation system in this studying site. | Takashi Tanaka Takahiro Sato Kazuo Watanabe Ying Wang Dan Yang Hiromo Inoue Kunzhi Li Tatsuya Inamura | 2013 | Journal of Environmental Sciences2013，25，6： | 8 |
| 18 | Optimal treatment strategies for hepatic portal venous gas:A retrospective assessment显示文摘BACKGROUND Hepatic portal venous gas(HPVG)generally indicates poor prognoses in patients with serious intestinal damage.Although surgical removal of the damaged portion is effective,some patients can recover with conservative treatments.AIM To establish an optimal treatment strategy for HPVG,we attempted to generate computed tomography(CT)-based criteria for determining surgical indication,and explored reliable prognostic factors in non-surgical cases.METHODS Thirty-four cases of HPVG(patients aged 34-99 years)were included.Necessity for surgery had been determined mainly by CT findings(i.e.free-air,embolism,lack of contrast enhancement of the intestinal wall,and intestinal pneumatosis).The clinical data,including treatment outcomes,were analyzed separately for the surgical cases and non-surgical cases.RESULTS Laparotomy was performed in eight cases(surgical cases).Seven patients(87.5%)survived but one(12.5%)died.In each case,severe intestinal damage was confirmed during surgery,and the necrotic portion,if present,was removed.Non-occlusive mesenteric ischemia was the most common cause(n=4).Twentysix cases were treated conservatively(non-surgical cases).Surgical treatments had been required for twelve but were abandoned because of the patients’poor general conditions.Surprisingly,however,three(25%)of the twelve inoperable patients survived.The remaining 14 of the 26 cases were diagnosed originally as being sufficiently cured by conservative treatments,and only one patient(7%)died.Comparative analyses of the fatal(n=10)and recovery(n=16)cases revealed that ascites,peritoneal irritation signs,and shock were significantly more frequent in the fatal cases.The mortality was 90%if two or all of these three clinical findings were detected.CONCLUSION HPVG related to intestinal necrosis requires surgery,and our CT-based criteria are probably useful to determine the surgical indication.In non-surgical cases,ascites,peritoneal irritation signs and shock were closely associated with poor prognoses,and are applicable as predictors of patients’prognoses. | Masanori Gonda Tatsuya Osuga Yoshihiro Ikura Kazunori Hasegawa Kentaro Kawasaki Takatoshi Nakashima | 2020 | World Journal of Gastroenterology2020，26，14： | 8 |
| 19 | Hepatectomy for hepatocellular carcinoma with portal vein tumor thrombus显示文摘Despite surgical removal of tumors with portal vein tumor thrombus(PVTT) in hepatocellular carcinoma(HCC) patients, early recurrence tends to occur, and overall survival(OS) periods remain extremely short. The role that hepatectomy may play in long-term survival for HCC with PVTT has not been established. The operative mortality of hepatectomy for HCC with PVTT has also not been reviewed. Hence, we reviewed recent literature to assess these parameters. The OS of patients who received hepatectomy in conjunction with multidisciplinary treatment tended to be superior to that of patients who did not. Multidisciplinary treatments included the following: preoperative radiotherapy on PVTT; preoperative transarterial chemoembolization(TACE); subcutaneous administration of interferon-alpha(IFN-α) and intra-arterial infusion of 5-fluorouracil(5-FU) with infusion chemotherapy in the affected hepatic artery; cisplatin, doxorubicin and 5-FU locally administered in the portal vein; and subcutaneous injection of IFN-α, adjuvant chemotherapy(5-FU + Adriamycin) administration via the portal vein with postoperative TACE, percutaneous isolated hepatic perfusion and hepatic artery infusion and/or portal vein chemotherapy. The highest reported rate of operative mortality was 9.3%. In conclusion, hepatectomy for patients affected by HCC with PVTT is safe, has low mortality and might prolong survival in conjunction with multidisciplinary treatment. | Toshiya Kamiyama Tatsuhiko Kakisaka Tatsuya Orimo Kenji Wakayama | 2017 | World Journal of Hepatology2017，9，36： | 8 |
| 20 | Near-infrared photoimmunotherapy of pancreatic cancer using an indocyanine green-labeled anti-tissue factor antibody显示文摘AIM To investigate near-infrared photoimmunotherapeutic effect mediated by an anti-tissue factor(TF) antibody conjugated to indocyanine green(ICG) in a pancreatic cancer model.METHODS Near-infrared photoimmunotherapy(NIR-PIT) is a highly selective tumor treatment that utilizes an antibody-photosensitizer conjugate administration, followed by NIR light exposure. Anti-TF antibody 1849-ICG conjugate was synthesized by labeling of rat IgG2 b anti-TF monoclonal antibody 1849(anti-TF 1849) to a NIR photosensitizer,ICG. The expression levels of TF in two human pancreatic cancer cell lines were examined by western blotting. Specific binding of the 1849-ICG to TF-expressing BxPC-3 cells was examined by fluorescence microscopy. NIR-PITinduced cell death was determined by cell viability imaging assay. In vivo longitudinal fluorescence imaging was used to explore the accumulation of 1849-ICG conjugate in xenograft tumors. To examine the effect of NIRPIT, tumor-bearing mice were separated into 5 groups:(1) 100 μg of 1849-ICG i.v. administration followed by NIR light exposure(50 J/cm2) on two consecutive days(Days 1 and 2);(2) NIR light exposure(50 J/cm2) only on two consecutive days(Days 1 and 2);(3) 100 μg of 1849-ICG i.v. administration;(4) 100 μg of unlabeled antiTF 1849 i.v. administration; and(5) the untreated control. Semiweekly tumor volume measurements, accompanied with histological and immunohistochemical(IHC) analyses of tumors, were performed 3 d after the 2nd irradiation with NIR light to monitor the effect of treatments. RESULTS High TF expression in BxPC-3 cells was observed via western blot analysis, concordant with the observed preferential binding with intracellular localization of 1849-ICG via fluorescence microscopy. NIR-PIT-induced cell death was observed by performing cell viability imaging assay. In contrast to the other test groups, tumor growth was significantly inhibited by NIR-PIT with a statistically significant difference in relative tumor volumes for 27 d after the treatment start date [2.83 ± 0.38(NIR-PIT) vs 5.42 ± 1.61(Untreated), vs 4.90 ± 0.87(NIR), vs 4.28 ±1.87(1849-ICG), vs 4.35 ± 1.42(anti-TF 1849), at Day 27, P < 0.05]. Tumors that received NIR-PIT showed evidence of necrotic cell death-associated features upon hematoxylin-eosin staining accompanied by a decrease in Ki-67-positive cells(a cell proliferation marker) by IHC examination.CONCLUSION The TF-targeted NIR-PIT with the 1849-ICG conjugate can potentially open a new platform for treatment of TF-expressing pancreatic cancer. | Winn Aung Atsushi B Tsuji Aya Sugyo Hiroki Takashima Masahiro Yasunaga Yasuhiro Matsumura Tatsuya Higashi | 2018 | World Journal of Gastroenterology2018，24，48： | 7 |
