Attenuated response to liver injury in moesin-deficient mice: impaired stellate cell migration and decreased fibrosis. Biochim Biophys Acta Mol Basis Dis 2008; 1782:542-8. [PMID: 18606220 DOI: 10.1016/j.bbadis.2008.06.006] [Citation(s) in RCA: 31] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2008] [Revised: 06/10/2008] [Accepted: 06/10/2008] [Indexed: 01/27/2023]
Abstract
Hepatic stellate cells (HSCs) respond to injury with a coordinated set of events (termed activation), which includes migration and upregulation of matrix protein production. Cell migration requires an intact actin cytoskeleton that is linked to the plasma membrane by ezrin-radixin-moesin (ERM) proteins. We have previously found that the linker protein in HSCs is exclusively moesin. Here, we describe HSC migration and fibrogenesis in moesin-deficient mice. We developed an acute liver injury model that involved focal thermal denaturation and common bile duct ligation. HSC migration and collagen deposition were assessed by immunohistology and quantitative real-time PCR. Activated HSCs were isolated from wild-type or moesin-deficient mice for direct examination of migration. Activated HSCs from wild-type mice were positive for moesin. Migration of moesin-deficient HSCs was significantly reduced. In a culture assay, 22.1% of normal HSCs migrated across a filter in 36 h. In contrast, only 1.3% of activated moesin-deficient HSCs migrated. Collagen deposition around the injury area similarly was reduced in moesin-deficient liver. The linker protein moesin is essential for HSC activation and migration in response to injury. Fibrogenesis is coupled to migration and reduced in moesin-deficient mice. Agents that target moesin may be beneficial for chronic progressive fibrosis.

Abstract
The quantity and quality of circulating DNA fragments was analyzed by quantitative real-time polymerase chain reactions (qPCR) in plasma from patients with esophageal and gastric cancer, in order to assess their diagnostic value. Plasma was collected preoperatively from 24 patients with esophageal cancer 53 patients with gastric cancer and from 21 healthy controls. qPCR was performed using two primer sets for the BETA-actin gene, amplifying short (102 bp) and long (253 bp) segments. The DNA concentrations in both the short and long segment assays of both cancer patients were significantly higher than the controls. The difference of concentrations between disease group and controls was more significant in esophageal cancer patients. The area under the receiver-operating characteristic curve was 0.83 (short) and 0.91 (long) for esophageal cancer patients, and 0.75 (short) and 0.67 (long) for gastric cancer versus the controls. There was also a significant difference in DNA integrity (short/long) between esophageal cancer patients and the control group (p = 0.001). qPCR assays for plasma DNA concentrations and their integrity can serve as new diagnostic markers for screening and monitoring patients with esophageal and gastric cancer.

Abstract
PURPOSE We aimed to clarify the prognostic impact of the anatomic extent of hepatic resection (Hr) related to the tumor hepatic involvement (H) on patients' survival in the treatment of hepatocellular carcinoma (HCC). METHOD The 305 patients with HCC who had undergone hepatectomy were analyzed retrospectively. The patients were classified into the anatomic wide hepatectomy (Hr > H hepatectomy, i.e. Hr was larger than H, n = 93) group and the other hepatectomies (Hr < or = H hepatectomy, i.e. Hr was equal to or smaller than H, n = 212) group. We compared the clinico-pathologic features between the two hepatectomy groups and the prognostic factors associated with postoperative HCC recurrence by using the Cox's proportional hazard model. RESULTS After median follow-up duration of 50 months (range 1-223 months), in Hr > H and Hr < or = H hepatectomy groups, the cumulative 3, 5, 10 year disease-free survival rates were 58.1, 44.6, 27.1% and 49.2, 33.0, 14.6%, respectively (P = 0.043). The overall survival was not significantly different between the groups (P = 0.401). Multivariate analysis revealed that Hr > H hepatectomy was an independent favorable factor for disease-free survival: the relative risk was 0.64 (95% confidence interval, 0.43-0.95; P = 0.026). CONCLUSION Anatomic wide (Hr > H) hepatectomy is a favorable procedure of choice in HCC for possibly reducing the risk of postoperative recurrence.

Abstract
BACKGROUND/AIMS The long-term outcome of patients undergoing repeated hepatectomy for secondary hepatocellular carcinoma (HCC) were investigated to assess the selection criteria for, and efficacy of, repeated hepatectomy. METHODOLOGY 21 patients with secondary HCC who had undergone repeated hepatectomy (R group) were analyzed. Clinical characteristics, histopathologic findings and postoperative clinical course were compared for patients with primary and secondary HCCs in the R group. The risk factors for post repeated hepatectomy survival and disease-free survival were estimated for the R group. RESULTS There were no significant differences in patient characteristics or histologic features of primary and secondary HCCs in the R group. A significant difference in cumulative postoperative disease-free survival was not seen for primary and secondary HCCs, average duration was 39.4 and 21.3 months. Liver cirrhosis and narrow hepatectomy (subsegmentectomy, limited resection and enucleation) were found to be significant risk factors of survival after secondary hepatectomy. The 5-year post-recurrence survival rate of nine patients in the R group who had two risk factors was 14.8%. CONCLUSIONS In cirrhotic patients with secondary HCC, inadequate narrow repeated hepatic resection should not receive repeated hepatectomy.

Abstract
This is the study of a 52-year-old man with oesophageal, rectal and anal varices caused by portal hypertension with complete obstruction of the superior mesenteric vein. Treatment by two sessions of interventional radiological procedures was successful. The first was a catheter-directed thrombolysis using the transmesenteric approach. The second was percutaneous transluminal angioplasty and stent implantation for the obstructed segment of the superior mesenteric vein and the creation of a transjugular intrahepatic portosystemic shunt. In the second session, devices were advanced over a guidewire inserted from the right jugular vein and pulled out of the ileocolic vein using the pull-through technique.

Abstract
A 69-year-old man was referred to our hospital for epigastralgia. He was found to have elevation of serum amylase and CA19-9. Ultrasonography, abdominal CT, MRCP, ERCP and EUS showed the cystic lesion and a possibility of an other tumor. There was a stenosis of the main pancreatic duct (MPD) at the pancreas head and dilatation of the MPD from the body to the tail. Intraductal papillary mucinous neoplasm (IPMN) of the branch pancreatic duct was diagnosed, and there was a likelihood of ductal carcinoma of the pancreas. We therefore performed pancreatoduodenectomy. Pathological finding showed invasive carcinoma from an intraductal papillary mucinous neoplasm with invasive ductal carcinoma of the pancreas.

Abstract
Primary peritoneal adenocarcinoma is rare, originating in the paramesonephric duct (müllerian duct). We report two cases of primary peritoneal adenocarcinoma. Both patients received a surgical resection. The pathological diagnosis of the resected specimen was papillary adenocarcinoma with clear cell carcinoma. The response after the combination chemotherapy using CDDP and TS-1 was "PR", and these treatments were effective to improve the patients' quality of life in each case.

Abstract
The greater omentum contains abundant lymphoid tissues composed of a lot of macrophages and lymphocytes, and plays an important role in a host defense system in the peritoneal cavity. Also, it is well known to be an initial site of peritoneal disseminated metastases. We experienced a rare case of a 60-year-old man with postoperative recurrence of esophageal cancer that presented itself in the greater omentum of the gastric tube reconstructed through a mediastinal route, as well as through mediastinal lymph-nodes. We performed CT-guided radiofrequency ablation (RFA) for recurrent omental tumor that was refractory to chemoradiation therapy and growing rapidly adjacent to the trachea. In combination with local control using RFA, we attempted a systemic immunotherapy using OK-432, by subcutaneous injection around RFA to accelerate host antitumor immune responses induced by antigen stimulation by RFA, based on the immunological property of the omentum. RFA induced a significant therapeutic effect on the omental tumor with massive necrotic change. However, no apparent size reduction was seen in the metastatic mediastinal lymph nodes, although an increase of peripheral blood lymphocytes was observed before and after RFA, and systemic host immune responses were stimulated by OK-432.

Abstract
We present the case of a 64-year-old male who was diagnosed with esophageal cancer with tracheal invasion and distant lymph node metastases, and he received chemoradiation therapy. The therapy resulted in complete remission. However, he was unable to eat anything because of missed swallowing caused by a large tracheoesophageal fistula. The placement of a covered self-expandable metallic stent (SEMS) improved his quality of life and palliated dysphagia for 3 months. Stenting in the cervical or upper esophagus may cause discomfort. However, the placement of a covered SEMS is one of the useful palliative treatments for esophageal cancer with tracheoesophageal fistula.

Abstract
We report a case of advanced multiple hepatocellular carcinomas (HCC), successfully treated by combination therapies of transarterial chemoembolization (TAE), operation and radiofrequency ablation therapy (RFA). A 59 year-old man was detected with an increased serum alpha-fetoprotein (AFP) level and an ultrasonography (US) revealed three nodules of HCC at the right lobe in August 1998. He was successfully treated with a combination therapy of TAE and percutaneous ethanol injection therapy (PEIT) at the beginning. However, HCC had recurred quite often. TAE had been repeated for twelve times before right trisegmentectomy was performed in November 2002. Thirteen months after the operation, CT revealed a new lesion at subsegment 3, which was treated by RFA. Furthermore, a metastatic single lesion had appeared at the left lung, which was resected. He has still been well for 82 months since the first detection of HCC.

Abstract
In the regional lymph node grouping of esophageal cancer by the Japanese Guide Line (the 9th edition), the location of the deepest tumor invasion has precedence in determination. In this study, we investigated the extending range of the tumor and the location of the deepest tumor invasion to ascertain which was the more important factor in predicting lymph node metastases. We examined 52 patients with distal thoracic esophageal and cardiac cancer who had undergone esophagectomy with three-field lymph node dis-section. Among the 52 patients, 16 were found to be positive and 36 negative, for middle-upper mediastinum and cervical lymph node metastases, and the two groups were compared in terms of detailed parameters of the tumor's location. In the result, the distance from the esophagogastric junction (EGJ) to the proximal margin of the tumor was significantly longer in the metastatic group (p=0.005). In univariate logistic regression with this parameter as the independent variable, we obtained a statistically significant result (p=0.0115, odds ratio=1.041, 95% confidence interval=1.009-1.073, R2=0.1169). On the other hand, when the distance from the EGJ to the deepest portion of the tumor was used as the independent variable, p=0.0742, odds ratio=1.045, 95% confidence interval=0.996-1.096 and R2=0.0577. Multiple logistic regression was performed with these two parameters, and the distance from the EGJ to the proximal margin of the tumor was a more important factor than the distance from the EGJ to the deepest portion of the tumor (p=0.0553 vs. 0.9161). We concluded that the extending range of the tumor was a more suitable predictive risk factor of lymph node metastases than the location of the deepest tumor invasion in distal thoracic esophageal and cardiac cancer. We should seriously consider the extending range of the tumor in the regional lymph node grouping of the Japanese Guide Line.

Abstract
To evaluate the efficacy of long-term postoperative adjuvant chemotherapy with low-dose cisplatin (CDDP) plus 5-fluorouracil (5-FU) (CDDP/5-FU), we retrospectively examined 167 patients with squamous cell carcinoma of the esophagus who received the treatment after curative surgery (R0 resection). We classified the patients into the following three groups according to their postoperative therapies and analyzed their outcomes: a) low-dose CDDP (10 mg body(-1) day(-1) x 5 days) plus 5-FU (250-500 mg body(-1) day(-1) x 5 days) repeated every 6 months for 3 years, with an oral fluoropyrimidine (5-FU 150-200 mg body(-1) day(-1) or UFT 300-400 mg body(-1) day(-1)) administered between each treatment cycle (low-dose CDDP/5-FU group, 98 patients); b) high-dose CDDP (80 mg body(-1) day(-1) x 1 day) plus 5-FU (750-1,000 mg body(-1) day(-1) x 5 days) administered once only, followed by treatment with an oral fluoropyrimidine (5-FU 150-200 mg body(-1) day(-1) or UFT 300-400 mg body(-1) day(-1)) for 3 years (high-dose CDDP/5-FU group, 17 patients); or c) surgery alone (surgery alone group, 52 patients). The 3-year survival rates were 83.7% in the low-dose CDDP/5-FU group, 61.4% in the high-dose CDDP/5-FU group, and 62.2% in the surgery alone group; the difference between the low-dose CDDP/5-FU group and surgery alone group was significant (log-rank, p<0.05). A significantly better outcome in the low-dose CDDP/5-FU group than in the surgery alone group was associated with pStage III disease (p<0.001), pN1 lymph node metastasis (p<0.001), and lymphatic invasion (p<0.01). We conclude that long-term postoperative treatment with low-dose CDDP/5-FU is therapeutically beneficial and prolongs survival in patients with esophageal cancer who have regional lymph node metastasis or lymphatic invasion.

Abstract
A 29-year-old female presented with upper abdominal pain. An upper gastrointestinal radiograph and endoscopy revealed an extra compression in the lesser curvature of the body of the stomach. A computed tomography scan and magnetic resonance imaging revealed a tumor located between the left lobe of the liver and the lesser omentum of the stomach. F-18 fluorodeoxyglucose positron emission tomography revealed high uptake at the tumor in the upper abdomen. In an angiogram, a large hypervascular mass had a prominent vascular supply from the left gastric artery; venous pooling and an enlarged feeding vessel were also apparent. From these results, we suspected that the patient had Castleman's disease arising from the lesser omentum. The patient underwent hand-assisted laparoscopic tumor resection. The resected tumor was an encapsulated mass, the surface of which was smooth and the dimensions of which were 77 x 51 x 43 mm. Based on microscopic findings, we diagnosed hyaline vascular type Castleman's disease. Since surgical intervention, the patient has remained asymptomatic, with no pathologic clinical or laboratory findings. Castleman's disease that occurs in the lesser omentum is extremely rare, and the preoperative diagnosis is very difficult. For the localized type of Castleman's disease, clinical findings are usually improved by complete surgical resection.

Abstract
The monoclonal antibody A7 (Mab A7) against human colonic cancer also reacts with human gastric cancer at a high rate. We produced a conjugate of neocarzinostatin (NCS) with Mab A7 (A7-NCS). The in vitro anticancer effect of A7-NCS on the antigen-positive human gastric cancer cell line MKN45 was stronger than that of free NCS. Nude mice models of peritoneal dissemination were established by the intra-peritoneal inoculation of MKN45. These models were divided into three groups. The anticancer effect observed in the group that received the intra peritoneal injection of A7-NCS was superior to that observed in the group that received the intra-venous injection and the group that received no treatment. In conclusion, the intra-peritoneal injection of A7-NCS was a useful treatment method for the peritoneal dissemination of gastric cancer.

Abstract
A 55-year-old man underwent a rectal amputation for rectal cancer in 1994. As the tumor marker was elevated in 2002, we performed an abdominal CT scan and detected local and multiple liver recurrences. We treated the patient with intra-arterial infusion of 5-FU/LV via the internal iliac artery and the hepatic artery. The chemotherapy was performed on a weekly basis; it consisted of 5-FU (500 mg/body), administered for 5 hours to bilateral reservoirs through an infusion pump and l-leucovorin (400 mg/body), administered intravenously for 2 hours. After 18 administrations of this regimen during a hospital stay and after a discharge from the hospital as an outpatient, the multiple liver metastases that were observed have disappeared. Further, the local recurrences showed a partial reduction in tumor size with a decrease in perineal pain. Subsequently, the patient did not require further doses of morphine. He exhibited no severe side effects except for grade 1 nausea, and his QOL was also good. Therefore, local intra-arterial infusion chemotherapy with 5-FU/LV appears to have been effective for rectal cancer recurrences.

Abstract
The patient was a 76-year-old man, diagnosed with sigmoid colon cancer with unresectable multible liver metastases. After sigmoidectomy with D2 regional lymphnode dissection on June 21, 2002 (moderately differentiated adenocarcinoma, ss, n(-), H3, P0, M(-), Stage IV), intermittent hepatic arterial infusion chemotherapy using 5-FU (1,250 mg/body/3 hr) and CDDP (10 mg/body/30 min) was performed weekly for 23 times, and then biweekly for 15 times. The total dosages of 5-FU were 47.5 g. During the regional chemotherapy, IFNANK therapy was performed biweekly as systemic immunotherapy. As a result, serum levels of tumor markers were remarkably decreased, and the metastatic liver tumors had disappeared in the CT finding in July 2003. Thereafter, IFNANK therapy was continued without the chemotherapy. However, CT and PET detected the recurrent liver tumors in December 2003, and the tumors were curatively resected on January 28, 2004.

Abstract
We have examined the utility of DDC as a novel marker for the detection of peritoneal micrometastases of gastric cancer. DDC mRNA in the peritoneal wash from 114 gastric cancer patients was quantified for a comparison of carcinoembryonic antigen (CEA) mRNA by means of real-time RT-PCR with a fluorescently labeled probe to predict peritoneal recurrence. The cut-off value was set at the upper limit of the quantitative value for non-cancer patients, and those above this cut-off value constituted the micrometastasis (MM+) group. Thirteen of 15 cases with peritoneal dissemination were MM+DDC (87% sensitivity), and one of 48 t1 cases was MM+ (98% specificity). DDC levels in peritoneal washes from patients with synchronous peritoneal metastases were more than 50 times higher than in those from patients without metastasis (p<0.01). For 15 cases of peritoneal dissemination (seven cases were cytologically positive), DDC was positive in 13 cases (87% sensitivity), but CEA failed to detect micrometastases in four cases (73% sensitivity), indicating that DDC is in some cases superior to CEA for the detection of peritoneal micrometastases of gastric cancer in terms of sensitivity as well as specificity, especially for poorly differentiated adenocarcinomas. Combination of CEA and DDC improved the accuracy of diagnosis up to 93%. These results suggest that DDC is potentially a novel marker for peritoneal dissemination of gastric cancer and that quantitative RT-PCR of DDC is reliable and efficient for the selection of patients for adjuvant intraperitoneal chemotherapy to prevent peritoneal recurrence.

Abstract
Hepatic arterial infusion (HAI) with pharmacokinetic modulating chemotherapy (PMC) has been well known to be one of the most effective protocols for unresectable liver metastases from colorectal cancer. PMC is a combination of oral UFT and continuous hepatic arterial 5-FU infusion. We present herein the cases of two patients with multiple liver metastases from colorectal cancer in whom complete regression (CR) was achieved by HAI with PMC in combination with Lentinan (immunostimulator). These patients received HAI via an implantable port system with a 4-24-hour continuous perfusion of 5-FU at 1,000 mg/m2 plus Lentinan at 2 mg/body once a week, and oral administration of UFT at 200-300 mg/m2/day everyday. CR of all metastatic lesions in the liver was achieved 4 months after the initiation of the treatment in both patients. One patient maintained CR for 3 months, but he died due to a recurrence of liver metastases and peritoneal dissemination 19 months after the initiation of the treatment. The other patient has been well without recurrence for 21 months. Because the liver is the largest immunologic organ, Lentinan could have activated lymphocytes and macrophages in the liver. Judging from the clinical experience of these two cases, HAI with PMC in combination with Lentinan could be one of the most promising treatment strategies for unresectable liver metastases from colorectal cancer.

Abstract
We describe a new method of sentinel node (SN) biopsy in the lower rectal cancer by a transsacral approach. Before the operation, an endoscopic clipping was performed around the tumor. The patient was placed in a jack knife position. A transverse incision was made over the S4-S5 joint. Subsequently, the S4-S5 joint was dissected, and the lower rectum was exposed without destroying the perirectal fatty tissue. CH-40 dye was injected into the submucosal layer of the rectal cancer. The lymph nodes that were blackened within 15 minutes were recognized to be SNs. Few investigations were reported with regard to sentinel node navigation surgery (SNNS) for lower rectal cancer, because the anatomical properties of the lower rectum make it difficult to inject the dye and recognize rectal tumors or lymph nodes. In our method, the lower rectum was exposed without destroying the perirectal fatty tissue, the dye was easily injected, and the SNs were easily found and extirpated. Our method of transsacral approach is considered to be useful.

Abstract
We report a case of diffuse type advanced hepatocellular carcinoma (HCC), which was successfully treated by a combination therapy of interferon-alpha (IFN) and 5-fluorouracil (5-FU). A 74-year-old man underwent distal gastrectomy 6 years ago for gastric cancer. In April 2002, an increased serum alpha-feto-protein (AFP) level was noted and a computed tomography (CT) of the abdomen revealed a diffuse type of HCC. He was treated with a combination therapy of IFN (5x10(6) units/body i.m., days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, 26) and 5-FU (500 mg/body/day i.a., days 1-5, 8-12 continuously). The treatment was repeated every 4 weeks with a maximum of five cycles. After 5 cycles, serum AFP levels fell from 665 ng/ml to a normal level. CT showed a reduced size of the tumor. He has been well and continue to receive IFN (3x10(6) units/body i.m., two times a week) and 5-FU (500 mg/body/day i.a., once a week) at the outpatient clinic for the last 16 months.

Abstract
We conducted a clinical study of cancer vaccine therapy with dendritic cells (DCs) and HLA-A24-restricted carcinoembryonic antigen (CEA)-derived peptide to assess the feasibility and efficacy of such therapy. Eighteen patients with CEA-expressing metastatic gastrointestinal or lung adenocarcinomas who were positive for human leukocyte antigen (HLA)-A24 were enrolled. DCs were generated from the patients' autologous monocyte-enriched fractions of granulocyte colony-stimulating factor-mobilized peripheral blood mononuclear cells in the presence of granulocyte/macrophage colony-stimulating factor and interleukin-4. The generated DCs were pulsed with CEA-derived, HLA-A24-restricted 9-mer peptide (CEA652) and injected into the patients intradermally and subcutaneously every 2 weeks. Toxicity and clinical and immunological responses were closely monitored in each patient. No severe toxicity directly attributable to the treatment was observed, and the vaccine was well tolerated. Although no definite tumor shrinkage occurred in any patient, long-term stable disease or marked decreases in the serum CEA level were observed in some patients after therapy. Most of the patients in whom treatment was clinically effective showed a positive skin response to CEA652-pulsed DCs (delayed-type hypersensitivity skin test) and a positive in vitro CTL response to CEA652 peptide after therapy. We conclude that active specific immunotherapy using DCs pulsed with CEA652 is a safe and feasible treatment that is clinically effective in some patients with metastatic gastrointestinal or lung adenocarcinomas. Our results will hopefully encourage further refinement and development of DC-based immunotherapy with HLA-A24-restricted CEA-derived peptide for refractory solid cancers that express CEA.

Abstract
PURPOSE Some patients with hepatocellular carcinoma (HCC) at an early stage cannot attain long-term survival after hepatectomy. The aim of the present study was to investigate the poor prognostic factors for hepatectomy in patients with resectable small HCC with cirrhosis. METHODS We studied 95 patients with cirrhosis with HCC, which consisted of a single tumor 5 cm or smaller or two or three tumor nodules each 3 cm or less; an absence of extrahepatic metastasis; and an absence of radiological evidence of macroscopic portal vein or hepatic vein invasion. We used Cox's proportional hazard model to identify risk factors associated with prognosis to determine the contra-indications for hepatectomy in patients with resectable small HCC. RESULTS Preoperative risk factors were: (1) serum AFP concentration of more than 400 ng/ml; (2) infiltrative-, massive-, or multinodular-type (multiple) HCC; and (3) the presence of intrahepatic metastasis. Patients who had had more than one of the three preoperative risk factors were poor candidates for hepatic resection, with a 4-year survival of 16.3%. CONCLUSION If patients with resectable small HCC are diagnosed as having more than one of three preoperative risk factors, they should not receive hepatectomy or should be considered for primary liver transplantation as a therapeutic option for HCC.
