Abstract
A highly reproducible and controllable deposition procedure for gold nanostructures on a titanium dioxide (TiO2) surface using femtosecond laser light has been demonstrated. This is realized by precisely focusing onto the TiO2 surface in the presence of a pure gold ion solution. The deposition is demonstrated both in dot arrays and line structures. Thanks to the multi-photon excitation, we observe that the deposition area of the nanostructures can be confined to a degree far greater than the diffraction limited focal spot. Finally, we demonstrate that catalytic activity with visible light irradiation is enhanced, proving the applicability of our new deposition technique to the catalytic field.

Abstract
BACKGROUND/AIMS The optimal treatment for locally advanced esophageal carcinoma has not yet been determined. We report results of neoadjuvant hyperthermo-chemoradiotherapy (HCRT) using weekly low-dose docetaxel followed by surgery in patients with advanced esophageal squamous cell carcinoma. METHODOLOGY Twenty-four patients were enrolled. 7 patients were considered to have inoperable tumors or rejected surgery after HCRT, and the remaining 17 patients had an esophagectomy. Clinical responses, HCRT toxicity and survival after surgery were evaluated. RESULTS In the 24 patients, the response rate was 41.7%. The pathological complete response (pCR) rate was 17.6% in the 17 patients. HCRT toxicity grade 2 occurred in six patients (25.0%: esophagitis, 4; leukopenia, 6; neutropenia, 4) and grade 3 (pneumonia) in 3 patients (12.5%). The 3- and 5-year survival rates were 56.3% and 50.0%, respectively. When the patients were divided into a pCR group and a pathological partial response (pPR) group, the 3-year survival rates were 66.7% and 42.9% and the 5-year survival rates were 66.7% and 42.9%, respectively (log-rank P = .5842). CONCLUSIONS Esophagectomy after docetaxel HCRT may have potential for prolonging survival in patients with locally advanced esophageal cancer. A larger randomized, controlled study will be required to confirm the benefit of esophagectomy after HCRT.

Abstract
BACKGROUND We performed a prospective, multi-institutional, phase-II, clinical trial of a docetaxel, nedaplatin, and 5-fluorouracil (DNF) regimen in patients with unresectable esophageal cancer. Our goal was to determine the efficacy and feasibility of this DNF protocol. METHODS Thirty-four patients with unresectable esophageal cancer were enrolled and received DNF therapy. The DNF regimen was repeated every 4 weeks for up to 8 weeks, based on the following recommended doses: docetaxel, 60 mg/m(2) (day 1); nedaplatin, 70 mg/m(2) (day 1); and 5-fluorouracil, 700 mg/m(2) (days 1-5). The primary endpoint was the response rate. The secondary endpoints were overall survival and chemotherapy toxicities. RESULTS The complete response rate and response rate were 5.9 and 47.1 %, respectively. The 2-year overall survival rate and progression-free survival rate were 44.3 and 27.3 %, respectively. The median survival time was 594 days. The median progression-free time was 277 days. No treatment-related deaths occurred. Thirty patients (30/34) with grade 3, 4 neutropenia improved relatively quickly with administration of granulocyte colony-stimulating factor. CONCLUSIONS DNF combination chemotherapy is a useful regimen with relatively minor adverse events and may serve as an effective protocol in patients with unresectable esophageal cancer.

Abstract
AIMS L-[3-(18)F]-α-Methyltyrosine ((18)F-FAMT) has high specificity for malignant tumors on positron emission tomography (PET), and its role and potential usefulness has been previously investigated in operable esophageal carcinoma. We aimed to assess the ability of (18)F-FAMT PET to predict the response of esophageal cancer to definitive chemoradiotherapy. PATIENTS AND METHODS We retrospectively reviewed 40 patients with esophageal cancer imaged with (18)F-FAMT PET. The relationship between (18)F-FAMT PET uptake before chemoradiotherapy and clinical outcomes was assessed. RESULTS The primary tumor was visualized in 95% patients. (18)F-FAMT uptake was significantly positively correlated with lymph node metastasis. The low-(18)F-FAMT accumulation group had significantly higher complete response (CR) rates than did the high-accumulation group. The addition of a lymph node metastasis category with low (18)F-FAMT uptake provides a more precise predictor of CR. CONCLUSION (18)F-FAMT uptake prior to treatment is a good predictor of CR rate after CRT for esophageal cancer.

Abstract
AIM The objective of the present study was to evaluate the significance of pre-treatment screening for patients with esophageal cancer. PATIENTS AND METHODS A retrospective evaluation of the clinical significance of total colonoscopy in 136 patients with primary esophageal cancer was performed. RESULTS Twenty-three patients (16.9%) had diverticula, and five (3.7%) had colon cancer. Benign polyps were present in 57 patients (41.9%); 37 of these patients underwent endoscopic treatment, one underwent surgery (esophagectomy). Twenty-seven out of 32 patients (84.4%) who underwent histopathological studies had tubular adenoma. Significant associations were found between presence of colorectal lesions and body weight, body-mass index (p<0.001), Brinkman index (p<0.001), and the Sake index (p<0.05). CONCLUSION Screening for colorectal lesions using total colonoscopy is important in patients with esophageal cancer, especially for those with a high body-mass index, and those who smoke or drink heavily.

Abstract
We reviewed the indications for re-thoracotomy after esophagectomy for esophageal cancer. Hemothorax, chylothorax, tracheobronchial injury (fistula), pneumothorax, and pyothorax were the main causes of re-thoracotomy. Indications for emergency thoracotomy were as follows. 1)Hemothorax:bleeding through the chest drain continuing at >100 ml/hour for ≥5 hour, or in cases when normal blood pressure cannot be maintained without blood transfusion. 2)Chylothorax:in cases with ≥1.5 l/day of chyle drainage for >5 days under conservative treatment. Healing is not seen for 14 days after conservative treatment. Nutritional status of the patient has worsened. 3)Tracheobronchial injury:at 1st respiration state should be understood. After we maintain the patient's airway, fistula is treated by closure and plombage with omentum or muscle flap. Appropriate diagnosis and timing are important for re-thoracotomy for complications after esophagectomy.

Abstract
Esophageal carcinosarcoma (ECS) is a rare malignant neoplasm associated with a poor patient prognosis. It is characterized by the presence of both malignant epithelial and mesenchymal components. Molecular-targeted therapy of several receptor tyrosine kinases (RTKs) has been reported to be effective in the treatment of various malignant tumors, including carcinosarcoma of several organs. This study aimed to assess the therapeutic potential of targeting RTKs in ECS. Overexpression of RTKs was assessed in 21 ECS cases by immunohistochemistry (IHC). Positively stained cases were further examined for RTK gene mutations and amplifications by direct sequencing analysis and fluorescence in situ hybridization. In epithelial components, KIT, platelet-derived growth factor receptor (PDGFR)A, PDGFRB, MET, epidermal growth factor receptor (EGFR) and HER-2 were overexpressed in 1 (4.8%), 1 (4.8%), 0 (0%), 11 (52.4%), 13 (61.9%) and 2 (9.5%) cases, respectively. In the mesenchymal components the corresponding numbers of cases were 2 (9.5%), 2 (9.5%), 0 (0%), 12 (57.1%), 11 (52.4%) and 0 (0%). No mutations in the c-kit, PDGFRA and c-met genes were found. Among 19 EGFR-positive tumors, 2 had EGFR missense mutations (T790A, exon 20) only in the mesenchymal component. Gene amplification or high polysomy of c-kit, PDGFRA, c-met and EGFR was observed in 1 (33.3%), 0 (0%), 3 (18.8%) and 10 (52.6%) cases, respectively. In conclusion, various RTKs, particularly MET and EGFR were overexpressed in ECSs suggesting that molecular-targeted therapies directed to MET, EGFR or other RTKs may be effective in inhibiting the growth or progression of the epithelial and/or mesenchymal component of ECS.

Abstract
Barrett's esophagus (BE) is the premalignant lesion from which esophageal adenocarcinoma near the esophagogastric junction arises. The management of BE and the treatment of Barrett's esophageal adenocarcinoma (BEA) are important clinical issues in Europe and the United States. As the Helicobacter pylori infection rate in Japan is decreasing in the younger population, the incidence of BE and adenocarcinoma arising from BE may start increasing. Thus, we review the current status of BEA and its management. Magnifying endoscopy with narrow-band imaging is important for diagnosing dysplasia arising from BE. In Japan, adenocarcinoma arising from BE is managed the same way as squamous cell carcinoma in the same location. Strategies to prevent BEA may include medication such as non-steroidal anti-inflammatory drugs and proton pump inhibitors, and anti-reflux surgery. Understanding the pathophysiology of BE will help to reduce the incidence of BEA.

Abstract
PURPOSE Nonspecific esophageal motility disorder (NEMD) is a vague category that includes patients with poorly defined contraction abnormalities observed during esophageal manometry. This study investigated the therapeutic effects of the video-assisted thoracoscopic surgery (VATS) approach using long myotomy and fundopexy for NEMD. METHODS The VATS approach using myotomy and fundopexy was performed for 4 patients of NEMD between 2005 and 2008. A total of 4 patients with NEMD that underwent treatment at our institution were analyzed retrospectively. RESULTS The patients included 2 males and 2 females with a median age of 48 years (range 21-74 years). The median duration of NEMD symptoms was 58 months (range 4-108 months). Dysphagia was a primary symptom in all patients. Chest pain was a primary symptom in 3 of 4 patients (75 %). Treatment with medication was attempted before the operation. The median operative time was 344.5 min (range 210-476 min). The median time before starting oral feeding was 2.5 days (range 2-22 days). All patients achieved a significant improvement of their previous condition. CONCLUSIONS The VATS approach using myotomy and fundopexy for NEMD is a good treatment in cases resistant to medication and balloon dilation.

Abstract
The association of microRNAs (miRs) with cancer progression has been established in many cancers including esophageal squamous cell carcinoma (ESCC). A public microarray database showed that the expression of miR-150 was lower in ESCC than in normal esophageal mucosa. Here, we focused on ZEB1, epithelial-mesenchymal-transition (EMT)-inducer, as a target gene of miR-150 based on in silico predictions. The purpose of this study was to clarify the clinicopathological significance of miR-150 in ESCC, and to investigate miR-150's EMT-regulatory ability. Quantitative RT-PCR was used to evaluate miR-150 expression in 108 curative resected ESCC samples to determine the clinicopathological significance. Moreover, we examined the in vitro and in vivo function of miR-150 via degradation of ZEB1. MiR-150 expression was significantly lower in cancer tissues compared to adjacent non-cancerous tissues (P < 0.001). Low expression of miR-150 in ESCC contributed to malignant potential, such as tumor depth, lymph node metastasis, lymphatic invasion, venous invasion, clinical staging, and poor prognosis (P < 0.05). In vitro assays showed that EMT-inducer-ZEB1 is a new direct target of miR-150. Moreover, miR-150 induced MET-like changes in TE-8 cells through ZEB1 degradation (e.g., E-cadherin expression, vimentin repression, epithelial morphology, and suppression of migration ability), and significantly inhibited tumorigenicity and tumor growth in a mouse xenograft model. Analysis of the regulation of ZEB1 by miR-150 could provide new insights into preventing metastasis and also suggests novel targeted therapeutic strategies in ESCC.

Abstract
BACKGROUND/AIMS Heat shock proteins (HSPs) are well known as tumor rejection antigens, most notable of which is HSP70. HSP110 is classified as a member of the HSP70/DnaK superfamily. The objective of this study was to clarify the clinicopathological and prognostic significance of Heat Shock Protein 110 expression and T lymphocyte infiltration in esophageal cancer. METHODOLOGY Immunohistochemical staining of HSP110, CD4 and CD8 were performed on surgical specimens obtained from 124 patients with esophageal cancer. RESULTS The expression of HSP110 correlated inversely with depth of invasion (p<0.0001), lymph node metastasis (p=0.0163), pathological stage (p<0.0001), lymphatic invasion (p=0.0104), blood vessel invasion (p=0.0027), infiltrative growth pattern (p=0.0368) and correlated positively with CD4+ T lymphocyte infiltration (p=0.0018). Reduction of HSP110 expression was significantly correlated with poor prognosis (p=0.0010). CONCLUSIONS The present findings suggest that HSP110 expression and T lymphocyte infiltration is a significant prognostic factor for esophageal cancer.

Abstract
BACKGROUND Tumor necrosis factor alpha-induced protein 8 (TNFAIP8) is a suppressor of TNF-α mediated apoptosis, and its expression is induced by NF-κB activation. TNFAIP8 expression is significantly increased in various cancer cell lines. A correlation between TNFAIP8 overexpression, cancer progression, and poor prognosis has been described in many reports of human solid cancers. METHODS To clarify the functional and clinical significance of the cancer progression-related gene, TNFAIP8, in esophageal squamous cell carcinoma (ESCC), we used immunohistochemistry to demonstrate TNFAIP8 expression in ESCC. Next, TNFAIP8 expression was depleted by using siRNA to examine the function of TNFAIP8 in the proliferation and apoptosis induction of ESCC cell lines. RESULTS We detected correlations between TNFAIP8 expression and TNM stage (P < 0.001), tumor depth (P = 0.002), lymph node metastasis (P = 0.013), distant metastasis (P = 0.001), lymphatic invasion (P < 0.001), and venous invasion (P < 0.001) among the clinicopathological characteristics of ESCC patients, and high TNFAIP8 expression was found in poor survival. TNFAIP8 depletion was significantly associated with apoptosis induction after cisplatin administration and reduced proliferation. CONCLUSIONS Our results suggest that TNFAIP8 might be an effective therapeutic target for ESCC in the future.

Abstract
Esophageal motility disorders are classified primary and secondary, and primary esophageal motility disorders are classified esophageal achalasia and other diseases by manometry. An esophageal emptying disorder associated with insufficient relaxation of the lower esophageal sphincter (LES) and elimination of peristaltic waves on the esophageal body is the major abnormality of achalasia. Esophagogram, endoscopy, and manometry are used for diagnosis. As pharmacological therapy, administration of a calcium channel blocker or nitrate is useful. The pharmacological therapy is not recommended as long-term basic therapy but as a temporary treatment. At 1st, the balloon dilation method is chosen in treatment of achalasia Surgical treatment is indicated in the following cases: (1) Patients uneffected by balloon dilation, (2) Flask type with grade II to III dilation, and sigmoid type, (3) the gradual progression to the pathophysiological stage, (4) young patients, (5) complicated with esophageal cancer. Laparoscopic Heller-Dor procedure is the most popular surgical procedure, recently. It is somewhat difficult to perform surgical treatment for this functional disease. We should select the most suitable individualized treatment with efficient comprehension of the pathophysiological situation.

Abstract
BACKGROUND CD151 is a member of the tetraspanins and has recently been reported as a promoter of the malignant progression of cancer. The purpose of this study was to clarify the clinicopathological outcome and prognostic significance of the immunohistochemical expression of CD151 in esophageal squamous cell carcinoma (ESCC). METHODS We evaluated the significance of CD151 expression by immunohistochemistry in 138 surgically resected ESCC and the association of CD151 expression with clinicopathological features. RESULTS Seventy-five (51.7%) ESCC showed a positive expression of CD151, which indicated a significant association with tumor depth (P = 0.004), lymph node metastasis (P = 0.002), distant metastasis (P = 0.025), and lymphatic invasion (P = 0.046), as well as the Ki-67 labeling index (P = 0.011). The 5-year survival rate of ESCC patients with CD151-positive expression was significantly lower than with CD151-negative expression (positive, 43.1%; negative, 63.8%; P = 0.003). Multivariate analysis showed that positive CD151 expression was not an independent factor for poor survival (P = 0.096). CONCLUSIONS CD151 expression is associated with tumor proliferation and invasiveness in ESCC.

Abstract
A 74-year-old woman was admitted to Gunma University Hospital because of dysphagia symptoms. A gastrointestinal contrast study demonstrated a large esophageal hiatal sliding hernia affecting the passage of barium at the lower end of the esophagus. Manometric studies showed hypotensive pressure in the lower esophageal sphincter (LES) and relaxation failure of the LES during swallowing. We diagnosed a combination of sliding hiatal hernia with nonspecific esophageal motility disorder (NEMD). Thoracoscopically assisted Heller myotomy and Dor fundoplication by abdominal open surgery were then performed. The patient is currently well and is free from dysphagia symptoms. Treatment with combination thoracoscopic and abdominal open surgery was effective. We report here the first case of combined hiatal hernia with NEMD treated by thoracoscopic and abdominal open surgery.

Abstract
BACKGROUND The role and potential usefulness of positron emission tomography (PET) scanning in certain tumors has been widely investigated in recent years. (18)F-FAMT (L-[3-(18)F]-α-methyltyrosine) is an amino acid tracer for PET. This study investigated whether PET/CT with (18)F-FAMT provides additional information for preoperative diagnostic workup of esophageal squamous cell carcinoma compared with that obtained by (18)F-FDG (fluorodeoxyglucose) PET or CT. METHODS PET/CT studies with (18)F-FAMT and (18)F-FDG were performed as a part of the preoperative workup in 21 patients with histologically confirmed esophageal squamous cell carcinoma. RESULTS For the detection of primary esophageal cancer, (18)F-FAMT-PET exhibited a sensitivity of 76.2%, whereas the sensitivity for (18)F-FDG-PET was 90.5% (P = 0.214). (18)F-FAMT uptake in primary tumors showed significant correlation with depth of invasion (P = 0.005), lymph node metastasis (P = 0.045), stage (P = 0.031), and lymphatic invasion (P = 0.029). In the evaluation of individual lymph node groups, (18)F-FAMT-PET exhibited 18.2% sensitivity, 100% specificity, 71.9% accuracy, 100% positive predictive value, and 70.0% negative predictive value, compared with 24.2%, 93.7%, 69.8%, 66.6%, and 70.2%, respectively, for (18)F FDG-PET. CT exhibited 39.4% sensitivity, 85.7% specificity, 69.8% accuracy, 59.1% positive predictive value, and 73.0% negative predictive value. The specificity of (18)F-FAMT-PET is significantly higher than that of (18)F-FDG-PET (P = 0.042) and CT (P = 0.002). (18)F-FAMT-PET did not have any false-positive findings compared to those with (18)F-FDG-PET. CONCLUSIONS Our findings suggest that the addition of (18)F-FAMT-PET to (18)F-FDG-PET and CT would permit more precise staging of esophageal cancer.

Abstract
BACKGROUND Karyopherin-alpha 2 (KPNA2) is a member of the importin alpha family and has recently been reported to play an important role in tumorigenesis and tumor progression. The aim of the current study was to elucidate the clinicopathological significance of immunohistochemical expression of KPNA2 in esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS KPNA2 expression was investigated by immunohistochemistry in 116 surgically resected ESCC, and the association of KPNA2 expression with clinicopathologic features was also examined. RESULTS Sixty (51.7%) ESCCs demonstrated positive expression of KPNA2. Positive expression of KPNA2 showed a significant association with poor differentiation (p=0.015), tumor depth (p=0.001), lymphatic invasion (p<0.001), venous invasion (p<0.001), and tumor stage (p=0.008). Positive expression of KPNA2 was also significantly associated with Ki-67 labeling index (p=0.039). Univariate analysis revealed that the prognosis of the ESCC patients whose tumors demonstrated positive expression of KPNA2 was significantly poorer than that of those that did not (p=0.009). Multivariate analysis revealed that only tumor depth and the presence of lymph node metastasis, which are strong prognostic factors in ESCC, were independently associated with poor prognosis in this study. CONCLUSION KPNA2 expression is associated with poor differentiation, tumor invasiveness, and tumor proliferation in ESCC.

Abstract
Cisplatin is a key chemotherapeutic agent for the treatment of esophageal cancer. We examined the intracellular localization of cisplatin in esophageal cancer cell lines and determined their sensitivity to cisplatin using in-air micro-PIXE (particle induced X-ray emission). Two human esophageal squamous cell carcinoma (ESCC) cell lines, TE-2 and TE-13, were examined for their response to cisplatin using MTT assay, flow cytometry, and DNA fragmentation assays. Real-time reverse transcription-polymerase chain reaction was also used to evaluate the mRNA expression of multidrug resistance protein 2 (MRP2) in both cell lines. Platinum localizations of intracellular and intranuclear were measured using in-air micro-PIXE. TE-2 cells were more sensitive to cisplatin than TE-13 cells (IC(50): 37.5 mum and 56.3 mum, respectively). Flow cytometry analysis confirmed that more TE-2 than TE-13 cells were in the sub-G1 phase. DNA fragmentation assay was analyzed to confirm the MTT assay and flow cytometry results. The expression of MRP2 mRNA in TE-13 cells was stronger than in TE-2 cells. In-air micro-PIXE showed that TE-2 cells had higher intracellular cisplatin concentrations than TE-13 cells and the ratio of intranuclear to intracellular cisplatin in individual cells was not significantly different. We observed the intracellular and intranuclear localization of cisplatin using in-air micro-PIXE. The results of this study suggest that in-air micro-PIXE could be a useful quantitative method for evaluating the cisplatin sensitivity of individual cells. Finally, we speculate that MRP2 in the cell membrane may play an important role in regulating the cisplatin sensitivity of ESCC cells.

Abstract
BACKGROUND Metabolic tumor activity using (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET) was believed to have a predictive value for patient outcome in malignancies. The objective of the current study was to assess the prognostic effectiveness of the highest standardized uptake value (SUV) in the primary or regional area (peak SUV) and the number of PET-positive lymph nodes in esophageal cancer. METHODS The authors retrospectively reviewed their experience with 184 consecutive esophageal cancer patients imaged preoperatively using FDG-PET scanning. RESULTS The median peak SUV was 4.5 (range, 1.4-21.9). The survival curve was analyzed using the median peak SUV as the cutoff value. Comparison of each group and clinicopathologic characteristics revealed significant associations between peak SUV and each of the following factors: tumor status (P < .001), lymph node status (P < .001), metastatic status (P < .05), stage of disease (P < .001), number of PET-positive lymph nodes (P < .001), and the number of histologically positive lymph nodes (P < .001). The 5-year overall survival (OS) rate for patients having FDG uptake with a peak SUV > or =4.5 was 47% and that for patients with a peak SUV <4.5 was 76% (P < .0001). On multivariate survival analysis using the Cox proportional hazards model, peak SUV and the number of PET-positive lymph nodes were found to be independent predictive factors for OS. The number of PET-positive lymph nodes was a single prognostic factor predicting both disease-free survival and OS. CONCLUSIONS Pretreatment PET cannot only potentially diagnose the extent of disease, but also may be predictive of patient survival after esophageal cancer resection.

Abstract
BACKGROUND Esophageal carcinosarcoma is a very rare neoplasm and its clinicopathological characteristics and the prognostic factors that influence the clinical outcome of the patient remain a matter of controversy. PATIENTS AND METHODS Twenty patients with esophageal carcinosarcoma were referred to our institutions. Tissue blocks were reviewed and sections containing both carcinomatous and sarcomatous components were stained for epithelial and mesenchymal markers and a proliferating cell marker. The prognosis of the esophageal carcinosarcoma patients was compared with 142 cases of esophageal squamous cell carcinoma. RESULTS In the carcinomatous component, the expression of cytokeratin, epithelial membrane antigen, vimentin, smooth muscle actin, and S100 were detected in 20, 20, 1, 1, and 1 case, respectively, whereas in the sarcomatous component, expression of these were detected in 4, 2, 18, 15, and 3 cases, respectively. The Ki-67 labeling index of carcinomatous and sarcomatous components was 35.5% and 41.8%, respectively. The 5-year survival rate was not statistically different between squamous cell carcinoma and carcinosarcoma (p=0.219). However, for T1 cases only, carcinosarcoma patients had statistically poorer prognosis than did squamous cell carcinoma patients (p=0.008). CONCLUSION The sarcomatous component shows various histological and immunohistochemical forms. In comparison with squamous cell carcinoma patients, carcinosarcoma patients had poorer prognosis amongst the T1 cases. For the treatment of esophageal carcinosarcoma, it is important to monitor lymph nodes and be watchful for hematogenous metastasis, as in cases of esophageal squamous cell carcinoma.

Abstract
BACKGROUND Lysyl oxidase (LOX), an extracellular matrix-remodeling enzyme, has been reported to regulate tumor metastasis. We investigated the clinical significance of LOX expression in esophageal squamous cell carcinoma (ESCC). METHODS We examined LOX expression in ESCC cell lines by real-time reverse-transcriptase polymerase chain reaction (RT-PCR) and Western blotting. We also examined LOX expression by real-time RT-PCR in 39 surgically resected ESCC and by immunohistochemistry in 122 surgically resected ESCC. RESULTS LOX messenger RNA (mRNA) was expressed at a high level in TTn (originating from an ESCC metastatic lesion); at a moderate level in TE-2 and TE-15; and at a low level in TE-1, TE-8, and TE-13. In Western blotting, all cell lines expressed the catalytically inactive 50-kDa LOX at approximately the same levels, but catalytically active 32-kDa LOX was overexpressed only in TTn. LOX mRNA levels in ESCC tissues were significantly higher than those observed in normal esophageal tissues (P < 0.001) and had no significant correlation with tumor-node-metastasis (TNM) factors. High LOX protein expression had a significant correlation with presence of lymph node metastasis (P = 0.009) and number of lymph node metastases (P = 0.047). Overall and cancer-specific survival rates of patients with ESCC with high LOX expression were significantly lower than those of patients with ESCC with low LOX expression (P = 0.024 and P = 0.012). Univariate and multivariate analyses revealed that high LOX protein expression was an independent prognostic factor for ESCC. CONCLUSIONS Our findings suggest that LOX can serve as a predictive marker of lymph node metastasis and prognosis in ESCC.

Abstract
BACKGROUND Failure of gap junction formation affects the development of various types of cancer. We aimed to clarify the clinicopathologic outcome and prognostic significance of connexin (Cx) 26 in human esophageal squamous cell carcinoma (ESCC). METHODS Immunohistochemical staining for Cx26 was performed on surgical specimens obtained from 123 patients with ESCC. RESULTS There was no positive staining for Cx26-specific expression in normal esophageal squamous cells. Primary ESCC with Cx26-positive expression was detected in the cytoplasm of cancer cell nests in 60 cases. Cx26 expression was correlated with N (lymph node metastasis, P = 0.014) and the number of metastatic lymph nodes (P = 0.047). The 5-year survival rates of ESCC patients with Cx26-positive expression were significantly lower than those with Cx26-negative expression (positive, 39.7%; negative, 65.7%; P = 0.007). By multivariate analysis, tumor-node-metastasis (TNM) clinical classification (T, P < 0.001; N, P = 0.002; M, P = 0.046) and Cx26 (P = 0.024) were independent prognosis predictors of ESCC. CONCLUSIONS These results suggest that abnormal expression of Cx26 participates in the progress of ESCC.

Abstract
The purpose of the present study was to assess the contribution of simultaneous functional/anatomical imaging using integrated 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT), compared with PET alone for the evaluation of initial lymph node staging in esophageal cancer. We studied 167 consecutive patients with thoracic esophageal squamous cell carcinoma (SCC) who had radical esophagectomy performed between January 1999 and April 2007. For individual nodal group evaluation, PET/CT showed 46.0% sensitivity (p<0.05 vs. PET), 99.4% specificity, 95.1% accuracy (p<0.05 vs. PET), 87.0% positive and 95.5% negative predictive values. PET showed 32.9% sensitivity, 98.9% specificity, 93.1% accuracy, 74.7% positive predictive value and 93.9% negative predictive value. Thus, the sensitivity and accuracy of PET/CT were significantly higher than those of PET. Comparisons between CT, PET and PET/CT in detecting lymph node metastasis by each region showed that PET/CT had a higher sensitivity in lower thoracic regions than PET and CT (p<0.05 vs. CT and PET). Lymph node staging (N0 vs. N1) was not significantly different, but staging per lymph nodal group was significantly better with PET/CT. Integrated PET/CT imaging with co-registration of anatomic and functional imaging data is useful in the initial lymph node staging of patients with operable esophageal cancer compared with PET alone.

Abstract
Diaphragmatic hernia complicating pregnancy is rare and is associated with high morbidity and mortality, particularly if surgical intervention is delayed. We report a case of diaphragmatic hernia in a pregnant 25-year-old woman. The patient was referred to our hospital in respiratory distress in the 28th week of her pregnancy. Chest radiograph and computed tomography showed air-filled bowel loops in the left side of the chest, with a marked mediastinal shift. Immediately after an emergency caesarean section, the herniated abdominal viscera were reduced through the opening in the diaphragm. We resected the ischemic segment of ileum and repaired the diaphragmatic defect with interrupted sutures and a Gore-Tex sheet. She had an uneventful postoperative course and her baby boy also recovered well. We report this case to alert surgeons to the possibility of this rare surgical emergency during pregnancy.

Abstract
Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms affecting the gastrointestinal tract. Esophageal GISTs are very rare, but recognition of esophageal GISTs has been increasing recently. We report a patient with an esophageal GIST that showed increased uptake on 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET). In this case, preoperative diagnosis was assumed to be esophageal cancer, but postoperative histopathological and immunohistochemical examination showed it to be a malignant GIST. We also found an activating mutation of kit in this patient; the mutation type was an in-frame deletion of a portion of the juxtamembrane domain (exon11). FDG-PET is useful not only for evaluating the bioactivity but also the malignant potential of esophageal GISTs.

Abstract
BACKGROUND Circulating vascular endothelial growth factor-C (VEGF-C) levels were measured in patients with esophageal cancer to assess the value of VEGF-C as a biomarker for predicting tumor recurrence. PATIENTS AND METHODS Preoperative serum samples were acquired from 80 patients and healthy volunteers who served as normal controls. VEGF-C levels were assessed using enzyme-linked immunosorbent assay (ELISA). RESULTS The preoperative serum VEGF-C level in patients with esophageal cancer was significantly higher than in healthy volunteers. Furthermore, patients with recurrence had significantly higher preoperative serum VEGF-C levels than patients without recurrence, and a high preoperative serum VEGF-C level was found to be an independent risk factor for recurrence, in addition to lymph node metastasis. CONCLUSION Preoperative VEGF-C levels may reflect malignancy, such as lymph node metastasis, and predict recurrence in patients with esophageal cancer. Therefore, the preoperative VEGF-C level may be a useful biomarker for choice of multimodality therapy.

Abstract
BACKGROUND After esophagectomy a swallowing abnormality is the predominant symptom for esophageal cancer. The aims of this study were to examine (i) oropharyngeal swallowing by comparing pre- and postoperative period, and (ii) the relationship between oropharyngeal swallowing and the alimentary reconstruction route after esophagectomy. PATIENTS AND METHODS We studied 27 patients in the upright position using videofluoroscopy in the lateral projection. Each patient was studied during 10 mL barium swallows in the pre- and post-operative period. RESULTS Of the 27 patients studied, alimentary reconstruction with the retrosternal route (RS group) was performed in 8 patients, that with posterior mediastinal route (PM group) in 8 patients, and the intrathoracic (IT group) esophagogastrostomy inside the posterior mediastinum in 11 patients. With regard to the maximal extent of structural movement, the superior and anterior excursion of the hyoid bone was significantly reduced postoperatively among all groups. The maximal extent of the cricopharyngeal opening was significantly reduced postoperatively in the RS group, but not in the IT group. The changes in the peri-operative structural movement were the lowest in the RS group. CONCLUSION A new-onset oropharyngeal swallowing abnormality following retrosternal reconstruction after esophagectomy may have appeared because the change in the peri-operative movement was the lowest. The results of the swallowing evaluation using videofluoroscopy suggest that to avoid oropharyngeal swallowing abnormalities the intrathoracic or cervical anastomosis with posterior mediastinal route should be chosen as reconstruction after esophagectomy if possible.

Abstract
BACKGROUND Positron emission tomography (PET) with 18-F-fluorodeoxyglucose (FDG) has already proven useful in assessing the extension of esophageal carcinomas, detecting tumor recurrence and monitoring responses to therapy. The current study aims to assess the potential role of FDG-PET in predicting the response of esophageal squamous cell carcinoma (SCC) to definitive chemoradiotherapy (CRT). PATIENTS AND METHODS Twenty-seven patients with thoracic esophageal SCC who received definitive CRT between January 2001 and December 2005 underwent PET before and after CRT. The clinical evaluation of the primary tumor response to treatment was classified as either complete response (CR) or non-CR. RESULTS All patients had intensive FDG uptake in the primary tumor prior to CRT. The standardized uptake value (SUV) averaged 8.2+/-4.7 before CRT and decreased significantly to 2.8+/-1.8 after CRT (p<0.0001). The SUV before CRT averaged 10.2 in the non-CR group (n=17) and 4.9 in the CR group (n= 10). The SUV after CRT averaged 3.7 in the non-CR group and 1.4 in the CR group. The change in SUV for the CR group was higher than that in the non-CR group (p<0.05). The relationship between clinical features and clinical CR was analyzed using logistic regression analysis which revealed significant correlations between clinical CR and the longitudinal dimension of the tumor (p <0.05), SUV before CRT (p<0.05), SUV after CRT (p<0.01) and tumor classification (p <0.05). If the clinical features before CRT were limited, multivariate analysis revealed that the SUV before CRT was an independent predictor for clinical CR (p<0.05). CONCLUSION In predicting clinical evaluation of therapy prior to CRT, we suggest that SUV prior to definitive CRT is one of the most reliable predictors of response, along with tumor dimensions and classification.

Abstract
Esophageal cancer is one of the most difficult malignancies to cure. The prognosis remains unsatisfactory despite significant advances in surgical techniques and perioperative management. The optimal treatment strategy for localized esophageal cancer has not yet been established. Surgical resection remains the mainstay of treatment for esophageal cancer, and curative resection is the most important surgery. Extended esophagectomy with three-field lymphadenectomy provides the highest quality of tumor clearance and prolongation of patient survival. There has been intense effort in developing novel strategies to treat patients with resectable esophageal cancer. Various combined-modality approaches have been attempted to improve treatment outcomes. Definitive chemoradiotherapy has an impact on long-term survival in patients with resectable esophageal cancer. Accordingly, there are three main combined-modality approaches: esophagectomy with adjuvant chemotherapy or chemoradiotherapy; primary definitive chemoradiotherapy with or without salvage esophagectomy, and preoperative chemoradiotherapy followed by planned esophagectomy. Recently, owing to the remarkable advances in optical technology, minimally invasive esophagectomy using endoscopic instruments has been introduced into esophageal cancer surgery. This article reviews recent changes in the treatment of esophageal cancer surgery, and considers the role of esophagectomy.

Abstract
We investigated whether Helicobacter pylori (HP) eradication increases the incidence of reflux esophagitis (RE) in patients with peptic ulcers. From 2001-2005 consecutive out patients with peptic ulcers and HP received eradication and were followed endoscopically. HP was cured in 119 and RE developed in 33 of the 153 patients. RE developed in 24 of the 119 HP-eradicated patients and 9 of the 34 HP-persistent patients. The estimated RE occurrence rate within 1 year was higher in the HP-eradicated patients than in the HP-persistent patients, but it was reversed at 2 years by the Kaplan-Meier analysis. In 76 patients follow up for > or = 18 months, hiatal hernia, duodenal ulcer, and eradication failure were significantly associated with the increased RE rate by univariate and multivariate analysis. The follow-up period after HP eradication affected the RE occurrence rate, and eradication failure significantly increased the RE development in patients followed up for > or = 18 months.

Abstract
BACKGROUND We have been investigating various molecules correlated with the malignancy of esophageal squamous cell carcinoma and, in the present study, we examined the correlation of four of them (KAI1, FAK, EphA2, Ki-67 labeling index) with the prognosis of affected patients. Furthermore, the use of biopsy samples was studied to evaluate whether the grade of tumor malignancy can be determined before treatment in a clinical setting. MATERIALS AND METHODS Tissue specimens that had been surgically removed from 91 patients with thoracic esophageal cancer and 247 biopsy samples were examined. The malignancy index (MI) was defined in terms of the KAI1, FAK and EphA2 scores and the Ki-67 labeling index, and the reliability and utility of the correlation between MI and prognosis was evaluated. RESULTS The mean 5-year survival rate of patients with MI=0 was 100%, while that of patients with MI=1, 2 and 3 was 70%, 48% and 10%, respectively. Patients with MI=4 all died, with the exception of one who has been observed for 3 years. The rate of concordance between the biopsy samples and surgical specimens was 79.4% for KAI1, 88.2% for FAK and 73.5% for EphA2, and the rates of concordance for 1, 2, 3, 4, 5, 6, 7 and 8 biopsy samples were 66.7%, 64.1%, 74.5%, 90.7%, 91.7%, 83.3%, 100% and 100%, respectively. CONCLUSION It may be feasible to evaluate the malignancy of tumor cells and to predict patient outcome by using multiple marker molecules. It is anticipated that such data will accelerate the development of "tailor-made" therapy.

Abstract
This report describes an exceedingly rare case of a benign cartilage-containing breast tumor that developed in the right breast of a 52-year-old woman. She found the mass on self examination. Physical examination revealed a 1.5 x 1.4 cm, firm, smooth and mobile lump in the lower medial quadrant close to the nipple of the right breast. Mammography revealed a slightly indistinct margined, oval-shaped, and high density nodule without microcalcifications. On ultrasonography, the lesion was a hypoechoic, oval-shaped mass with an echogenic spot. The border was slightly rough. Fine needle aspiration cytology revealed some giant cells and necrotic tissue. Excisional biopsy was then performed. Histopathologically, the lesion consisted of islands of mature hyaline cartilage with intervening strands of fibrous stroma. Mammary lobules and ducts were lacking within the mass. Fat and muscular components were not present. Therefore chondromatous tumor of the breast was diagnosed.

Abstract
BACKGROUND Intensive care unit (ICU) psychosis is still a relatively frequent complication after esophageal surgery. We investigated the correlation between ICU psychosis and serum melatonin concentration during the period after esophagectomy. METHODS The study group comprised 41 patients who underwent esophagectomy for treatment of esophageal cancer between 1999 and 2001. The cohort included 36 men and 5 women, aged 36 to 78 years. After surgery, blood samples were collected 4 times a day for 4 days. Serum levels of melatonin were determined with a melatonin radioimmunoassay kit. The regularity of the melatonin circadian rhythm pattern, as defined by the frequency of occurrence of the peak level of melatonin secretion, was determined (the pattern was described as irregular at less than 3 times in the measurement period). RESULTS Of the 41 patients who met the inclusion criteria, 11 (26.8%) had ICU psychosis develop. These patients were older than those patients in whom ICU psychosis did not develop (P =.01). No significant differences were seen in the duration of surgery, volume of blood loss, term in the ICU, term of intubation, tumor location, disturbances of organ function, and postoperative complications between patients in whom ICU psychosis developed, and those patients in whom it did not. Patients with ICU psychosis tended to have abnormally low serum levels of melatonin. Of the 41 patients studied, 9 (22%) had an irregular pattern of melatonin circadian rhythm. A significant correlation was seen between ICU psychosis and an irregular melatonin circadian rhythm (P =.0001). CONCLUSION Irregular patterns of melatonin circadian rhythm may be associated with ICU psychosis. Supplementation with melatonin, or acceleration of melatonin secretion, may protect patients from development of ICU psychosis and may promote recovery to a normal mental state.

Abstract
We report four patients with a new type of familial parkinsonism and dementia consisting of an autosomal dominant inheritance, dopa-responsive parkinsonism, severe dementia, variable myoclonus and autonomic disturbances. Autopsy of two patients revealed symmetrical cerebral atrophy with fronto-temporal dominant distribution, and marked depigmentation in the substantia nigra and locus ceruleus. Neuronal loss and gliosis were observed in the deep cerebral cortex and amygdala as well as in the areas vulnerable to Parkinson's disease. In the cerebral cortex, swollen neurons with frequent granulovacuolar changes were observed, consisting of ballooned neurons and those with argyrophilic intracytoplasmic inclusions, in addition to neuropil threads. Atypical neurofibrillary tangles, which barely stained with tau antibodies, were numerous in the upper cortical layers, consisting of 15-nm straight tubules. In addition, tau-negative astrocytic fibrillary tangles were also frequent. Electron microscopically, the ballooned neurons and argyrophilic neuronal inclusions contained filamentous structures coated with fuzzy electron-dense deposits. The inclusions showed immunohistochemical features different from those of cortical Lewy bodies and Pick bodies. Occasional Lewy bodies were present in the brain stem lesions of both patients. In two of our patients, the pathology in the brain stem was similar to that of Parkinson's disease, whereas their cerebral pathology was unusual and has not been reported previously.

Abstract
Cells of the yeast Saccharomyces cerevisiae sporulated in nutrient-rich medium containing L-lysine. Sporulation was specific to the presence of L-lysine and was initiated when the cellular content of this basic amino acid reached approximately 0.2-0.5 mmol (g cells)-1, at early stationary phase. The formation of asci was most efficient at pH 7.0 and 50-100 mM L-lysine; in these optimum conditions, the sporulation frequency reached about 60% after 5 d incubation. The L-lysine-dependent sporulation system in nutrient-rich conditions was distinct from the currently used potassium-acetate-dependent system in nutrient-deficient conditions. Analysis of the L-lysine-dependent system indicated that, prior to entrance into meiosis and/or sporulation processes, the yeast cells change in shape, their pool sizes for L-cysteine and glutathione alter, and they synthesize a protein with a molecular mass of 15 kDa. A low level of cAMP was not required for the entrance into meiosis and/or sporulation.

Abstract
We describe a clinico-pathological variant of a degenerative disorder involving Broca's, Wernicke's, and supplementary motor areas, which presented as primary progressive aphasia, dysarthria, bucco-facial apraxia, and hearing loss as initial symptoms, followed by organic personality changes. Postmortem examination revealed severe focal atrophy of the cerebral convolutions in the frontal operculum, superior frontal gyrus, and superior and transverse temporal gyri in addition to diffuse atrophy of the frontal and temporal lobes in both hemispheres. Microscopical examination revealed argyrophilic neuronal inclusions (ANIs) in the neuronal perikarya and presynaptic terminal throughout the central nervous system, as well as neuronal loss and swollen chromatolytic neurons in the affected cortices. Neocortical ANIs showed a positive immunoreaction with an anti-tau antibody but only a weak reaction with an anti-ubiquitin antibody immunohistochemically. Ultrastructurally, neocortical ANIs consisted of 15-nm thick smooth-surfaced tubules and tubules with constrictions at 120-150-nm intervals; thus they were different from the typical paired helical filaments of the 80-nm interval constrictions observed in the subiculum. ANIs were also found in the basal ganglia, brain stem nuclei, and cervical cord. Accordingly, ANIs appear distinct from neurofibrillary tangles (NFTs) of progressive supranuclear palsy, NFTs of Alzheimer-type dementia, and Pick bodies. The authors consider that this case fits the histopathological criteria of corticonigral degeneration with neuronal achromasia except for the unusual extension to the temporal lobes.

Abstract
Degeneration of heterogeneous systems in the central nervous system, with widespread distribution of argyrophilic neuronal fibrillary inclusions, was found in a patient with presenile dementia. Atrophy was circumscribed in the frontal and temporal lobes. Neuronal loss was severe in the basal ganglia, subthalamic nucleus, and substantia nigra. Immunocytochemical study using anti-phosphorylated tau and anti-ubiquitin antibodies in conjunction with ultrastructural observations revealed two types of inclusions: neurofibrillary tangles (NFTs) of progressive supranuclear palsy (PSP) in the Edinger-Westphal nucleus, locus coeruleus, cerebellar dentate nucleus, inferior olivary nucleus, and posterior horn of the spinal cord; and Pick bodies (PBs) in the atrophied cerebral cortex and red nucleus. PSP-type NFTs and PBs have been demonstrated in a single case for the first time. Despite their pathognomonic significance in certain disorders, we suggest that these inclusions may reflect a form of cytoskeletal disorganization, which is not entirely restricted to a single disease entity.

Abstract
Neuronal alterations in five cases of multiple system atrophy (MSA) were investigated histologically, immunocytochemically and ultrastructurally. Argentophilic neuronal cytoplasmic inclusions (NCIs) were observed in all cases. They were distributed, in order of decreasing frequency, in the pontine nucleus, striatum, subiculum, amygdala, hippocampus, dentate fascia, substantia nigra and inferior olivary nucleus. Anti-ubiquitin antibodies visualized many thickened neurites in the degenerating gray matter as well as NCIs. Some NCIs were also recognized by anti-phosphorylated neurofilament antibodies. Ultrastructurally, NCIs consisted of a meshwork of granule-associated filaments, the diameter ranging from 18 to 28 nm, that were mixed with neurofilaments. The granule-associated filaments were also present in the axoplasm of myelinated fibers. Our studies demonstrate widespread distribution of NCIs in the central nervous system of MSA. The same pathological process that forms the granule-associated filaments in axons may also be responsible for the formation of ubiquitin-positive thickened neurites. These axonal alterations, as well as neuronal perikaryal changes, may play an important role in the impaired neuronal function in MSA.

Abstract
Oligodendroglial cytoplasmic inclusions (OCI) in multiple system atrophy were investigated immunocytochemically and ultrastructurally. Among the 17 cases examined, 16 had OCIs. Almost all OCIs were positive for both alpha B-crystallin and ubiquitin. The antibodies against tubulin, paired helical filament and tau stained OCIs to various extents. Ultrastructurally OCIs consisted of meshworks of granule-associated filaments about 25 nm in diameter that sometimes formed flame-shaped tangle-like structures. Immunoelectron microscopy showed that an epitope of alpha B-crystallin was located on the granule-associated filaments composing OCIs. Our studies further support a cooperative role of alpha B-crystallin, ubiquitin and cytoskeletal protein in the formation of some types of intracytoplasmic inclusions.
