Abstract
Prognosis of patients with recurrent esophageal cancer is usually unsatisfactory. We have successfully treated five patients with cervical node recurrence after esophagectomy with multimodal treatment including salvage lymphadenectomy. In order to clarify the efficacy of salvage surgery for cervical node recurrence, we have reviewed the clinical course and prognosis of these patients. From August 2004 to December 2007, 30 patients with 33 recurrent sites were treated in the Department of Surgery, Iizuka Hospital. Among these patients, there were five patients with recurrence limited within the cervical nodes. Salvage cervical lymphadenectomy was performed for all five patients. Curative resection was achieved in four patients and reduction surgery followed by planned chemoradiotherapy was performed in another patient. All stations including the suspicious node were dissected and a partial sternotomy was added for one patient whose recurrent tumor was located in the right recurrent nerve node. There was no mortality and one minor complication (subcutaneous hemorrhage) was observed. Median duration of hospital stay was 7 days. Adjuvant chemotherapy was performed for all patients. Median follow-up period was 54 months and all patients are alive without relapse of the disease. Salvage cervical lymphadenectomy is a safe and effective treatment for patients with cervical node recurrence after esophagectomy.

Abstract
BACKGROUND Bosentan is an oral dual endothelin receptor antagonist, which has been shown to be efficacious for preventing new digital ulcers in patients with systemic sclerosis (SSc) in two high-quality randomized controlled trials. However, its efficacy for nondigital ulcers in SSc remains unknown. OBJECTIVES To evaluate the efficacy of bosentan on nondigital ulcers in patients with SSc. METHODS Bosentan was administered to five patients with SSc with pulmonary arterial hypertension, who also had nondigital ulcers refractory to conventional treatments. The efficacy of bosentan on nondigital ulcers and its association with clinical features of ulcers were analysed. RESULTS The nondigital ulcers refractory to conventional treatments were significantly improved by the administration of bosentan in cases surrounded with severe cyanosis. In contrast, nondigital ulcers without cyanosis were still refractory to bosentan therapy. CONCLUSIONS Bosentan may be efficacious for accelerating the healing of nondigital ulcers with severe cyanosis, suggesting that nondigital ulcers caused by severely impaired peripheral circulation are highly responsive to this treatment.

Abstract
Since the neuroradiological features of patients with 22q11.2 deletion syndrome are not well-understood, examinations using functional imaging were performed in this study. Brain magnetic resonance imaging (MRI) and 1H-magnetic resonance spectroscopy (MRS) were performed using a clinical 3-Tesla MR imager in 4 patients with 22q11.2 deletion syndrome (2 boys and 2 girls; aged 2-6 years.) and 20 age- and sex-matched healthy control subjects. Furthermore, interictal 123I-iomazenil (IMZ) single photon emission computed tomography (SPECT) was examined in 2 of the 4 patients. Among the 4 patients with 22q11.2 deletion syndrome, 2 patients showed polymicrogyria and 1 patient showed agyria. Those patients with brain malformations also showed abnormal brain artery patterns and decreased accumulation of IMZ in 123I-IMZ SPECT. Although all 4 patients showed epileptic discharges in their electroencephalograms (EEG), one patient with polymicrogyria had no seizure episodes. Decreases in γ-aminobutyric acid (GABA) corresponding to the areas of polymicrogyria and/or epileptic discharges in EEG were shown in all patients except for the patient with agyria. Although consistent evidence was not seen in patients with 22q11.2 deletion syndrome in this study, brain malformations and disturbances of the GABAergic nervous system would be underlying mechanisms of the neurodevelopmental abnormalities in this syndrome.

Abstract
Spirometry is practically the only tool to evaluate pulmonary functions. Other automatic systems comparable to spirometry are expected. A fiber-grating (FG) vision sensor is a non-contact respiratory monitoring system to detect changes in volumes by measuring the movement of laser spots on the body surface. We examined the contributions of the FG sensor to evaluating pulmonary functions. The FG sensor showed a linear correlation with spirometry in tidal volumes (TV) obtained from five controls (R = 0.98, P < 0.0001). We also showed agreement of TV between the two devices using Bland-Altman analysis. TV measured by the FG sensor were reproducible and applicable to distinct subjects. To detect airway obstruction, we performed forced expiration in controls (n = 16) and chronic obstructive pulmonary disease (COPD) patients (n = 18) with the FG sensor and spirometry. Forced expiratory volume in 1 s (FEV(1)) and FEV(1)/forced vital capacity in COPD patients were lower than those in controls by the FG sensor. In addition, prolonged expiration in natural breathing by the FG sensor was related to airflow limitation by spirometry. The FG sensor was helpful to measure volume changes and to evaluate pulmonary functions in controls and patients with COPD. Its upcoming clinical applications are promising for simplicity and feasibility.

Abstract
The effects of proteolytic enzyme inhibitors, aprotinin, soybean trypsin inhibitor and camostat mesilate as absorption enhancers on the transdermal iontophoretic delivery of salmon calcitonin (SCT) have been examined in rats. The dermal absorption of SCT was evaluated with hypocalcaemic effect. Application of SCT (12·5 int. units/rat) onto abdominal skin did not produce any hypocalcaemic effect. This produced a small hypocalcaemic effect with cationic iontophoresis (drug phase, anode; reference phase, cathode; high frequency pulses of 1 V at 10 kHz, 2h). Furthermore, camostat mesilate (1 Mm) and aprotinin (106 int. units mL−1) enhanced the hypocalcaemic effects on the application of SCT with iontophoresis. These hypocalcaemic effects were highest with the pH 4·0 preparation compared with those of the pH 5·5, pH 7·0 and pH 8·0 preparations. However, soybean trypsin inhibitor did not change the hypocalcaemic effects. This was because the soybean trypsin inhibitor is a relatively high molecular weight peptide (mol. wt 8000) and an anion at used pH, and therefore was not absorbed through rat skins with cation iontophoresis.

Abstract
We report the case of a 31-year-old male with enlarged kidneys and glomerulocystic kidney disease (GCKD). The patient had no family history of renal disease or other diseases. On initial presentation he complained of poor eyesight, and hypertensive retinopathy and elevated serum creatinine (5.0 mg/dl) were found at that time. Renal biopsy showed cystic dilatation of Bowman's capsule and atrophy of the glomerular tuft. Thus, an adult case of sporadic GCKD was diagnosed. Based on previous reports, kidney size in patients with adult type GCKD varies from small to large. Our patient's kidneys are the largest ever reported (right kidney was 22 cm×10 cm, left kidney was 19 cm×10 cm). A review of the literature dealing with sporadic adult GCKD suggested that it is difficult to diagnose this disease early in its course.

Abstract
Chymase plays a crucial role in angiotensin II formation in various tissues. Angiotensin II induces gene expressions of transforming growth factor (TGF)-β and matrix metalloproteinase (MMP)-9, and chymase also converts precursors of TGF-β and MMP-9 to their active forms. All of angiotensin II, TGF-β and MMP-9 are considered to be closely involved in the development and progression of metabolic syndrome and its complications. In a diabetic animal model, chymase induced pancreatic disorganization via attack of oxidative stress induced by augmentation of chymase-forming angiotensin II. In atherosclerotic lesions in patients, accumulation of chymase-positive cells was observed, and chymase inhibition prevented the development of atherosclerosis in an animal model. In Apo E-deficient mice, chymase inhibition prevents the development of angiotensin II-induced abdominal aneurysmal aorta (AAA). In this model, the AAA development on an increase in MMP-9 activities induced by angiotensin II, but the inhibition of MMP-9 activation by chymase inhibitor resulted in attenuation of the AAA development. Cardiac dysfunction after myocardial infarction was also attenuated by chymase inhibition. Steatosis and fiblosis in liver were strongly prevented by chymase inhibition in an animal model with nonalcoholic steatohepatitis which is involved in metabolic syndrome. Therefore, chymase inhibition may be useful for attenuating MMP-9 and TGF-β levels, in addition to reducing angiotensin II formation, and this function may provide powerful preventions of organ damages. In this review, we propose the significance of chymase as a target to prevent complications of metabolic syndrome.

Abstract
Background
The systemic management of metastatic breast cancer patients is usually based on biological marker of the primary tumor. However, characteristics of hormone status or HER2 over expression may change with metastatic site due to long term treatment for metastatic cancer with endocrine therapy, chemotherapy or biologic agents. The first purpose of this study was to investigate the concordance in HER2 over expression between primary tumor and distant metastases. The second purpose was to evaluate the efficacy of biologic agents for the patients with positive changes in HER2 status.
Material and methods One hundred forty-one patients had biopsy or operation of their metastatic site from 2000 to December 2009 at the Chiba Cancer Center Hospital. Specimen of operation or biopsies of suspected metastatic site were obtained from breast cancer patients. Specimen were analyzed pathologically to confirm metastatic disease and secondly to evaluate
HER2 by immunohistochemistry or FISH.
Results
Specimen of metastatic site were 67 local lesion (breast or lymph node), 27 brain, 16 liver, 12 bone and 5 others organs (stomach, intestine, ovary or uterus. Negative, positive or no change in HER2 status was observed in 4%, 6%, and 90% respectively. Positive changes of HER2 in metastatic site were 3(4%) local lesion, 3(11%) brain, 1 (7%) lung, 0(0%) liver, 2(17%) bone, and 0(0%) others, respectively. Three patients with positive change in HER2 status of metastatic site were treated to trastuzumab. Two of 3 patients with HER2 positive change were assessed to responded to trastuzumab-based treatment schedules.
Conclusions This study demonstrates the presence of substantial discordance in HER2 overexpression between primary tumor and metastases site.Metastatic tissue confirmation might be considered in patients with suspicious metastatic recurrence or resistance trastuzumab treatment.

Abstract
Abstract
Introduction: Sentinel lymph node biopsy (SLNB) for breast cancer has been established. The objective of this study was to investigate factors which elevate the identification rate employing the dye method (DYm) alone.
Subjects: The subjects were 1,081 cN0 breast cancer patients who underwent preoperative cytology of the axillary lymph nodes at our facility between May 2001 and April 2010.
Methods: In the morning of the operation day, 0.3 ml of technetium phytate was subcutaneously injected immediately above the tumor, and 5 ml of indigocarmine was subcutaneously injected into the para-areolar region on the axillary side immediately before surgery, attempting to identify sentinel lymph nodes (SLN) using the combination method. The rates of identification employing the DYm and RI method (Rim) and false-negative rates were calculated. Regarding SLN in which the highest count was detected by the RIm as the first SLN (fSLN), consistency with that detected using the DYm was investigated.
Results: The mean numbers of SLN identified by the DYm and RIm were 1.36 and 1.90, respectively, showing that significantly more lesions were identified employing the RIm (P<0.05). The identification rates employing the dye, RI, and both methods were 88.7, 98.7, and 99.3%, respectively, and the consistency of fSLN between the DYm and RIm was 78.1%. SLN metastasis detected using the RIm could not be identified employing the dye method in 20 cases. The age, tumor size, and BMI were investigated in these 20 cases, and a significant difference was noted in the tumor size. Conclusion: The identification rate employing the DYm alone was lower than that employing the RIm. The consistency of fSLN between the two methods was 78.1%. Although the RIm may have biopsied excess lymph nodes (LN), its use may be important to complement the DYm. Dye does not readily enter metastatic LN because of the presence of tumor plugs. The application of preoperative axillary LN cytology to cases with large tumors to exclude metastasis-positive cases may elevate the SLN identification rate employing the DYm.

Abstract
BACKGROUND Intracellular phosphoprotein activation significantly regulates cancer progression. However, the significance of circulating phosphoproteins in the blood remains unknown. We investigated the serum phosphoprotein profile involved in pancreatic cancer (PaCa) by a novel approach that comprehensively measured serum phosphoproteins levels, and clinically applied this method to the detection of PaCa. METHODS We analysed the serum phosphoproteins that comprised cancer cellular signal pathways by comparing sera from PaCa patients and benign controls including healthy volunteers (HVs) and pancreatitis patients. RESULTS Hierarchical clustering analysis between PaCa patients and HVs revealed differential pathway-specific profiles. In particular, the components of the extracellular signal-regulated kinase (ERK) signalling pathway were significantly increased in the sera of PaCa patients compared with HVs. The positive rate of p-ERK1/2 (82%) was found to be superior to that of CA19-9 (53%) for early stage PaCa. For the combination of these serum levels, the area under the receiver-operator characteristics curves was showing significant ability to distinguish between the two populations in independent validation set, and between cancer and non-cancer populations in another validation set. CONCLUSION The comprehensive measurement of serum cell signal phosphoproteins is useful for the detection of PaCa. Further investigations will lead to the implementation of tailor-made molecular-targeted therapeutics.

Abstract
In hepatitis C virus (HCV) infection, the Th1-type immune response is involved in liver injury. A predominance of immunosuppressive regulatory T cells (Treg) is hypothesized in patients with persistently normal alanine aminotransferase (PNALT). Our aim was to clarify the role of Treg in the pathogenesis of PNALT. Fifteen chronically HCV-infected patients with PNALT, 21 with elevated ALT (CH) and 19 healthy subjects (HS) were enrolled. We determined naturally-occurring Treg (N-Treg) as CD4+CD25high+FOXP3+ T cells. The expression of FOXP3 and CTLA4 in CD4+CD25high+ cells was quantified by real-time reverse transcriptase-polymerase chain reaction. Bulk or CD25-depleted CD4+ T cells cultured with HCV-NS5 loaded dendritic cells were assayed for their proliferation and cytokine release. We examined CD127-CD25-FOXP3+ cells as distinct subsets other than CD25+ N-Treg. The frequencies of N-Treg in patients were significantly higher than those in HS. The FOXP3 and CTLA4 transcripts were higher in PNALT than those in CH. The depletion of CD25+ cells enhanced HCV-specific T cell responses, showing that co-existing CD25+ cells are suppressive. Such inhibitory capacity was more potent in PNALT. The frequency of CD4+CD127-CD25-FOXP3+ cells was higher in CH than those in PNALT. Treg are more abundant in HCV-infected patients, and their suppressor ability is more potent in patients with PNALT than in those with active hepatitis.

Abstract
AIMS HSP60 plays a protective role against heat, oxidative injury and ultraviolet. Recently, animal and clinical studies have suggested that HSP60 plays a role in various diseases. However, few epidemiological studies have demonstrated an association between HSP60 levels and type 2 diabetes mellitus. Therefore, an epidemiological study was conducted to examine the association of HSP60 with type 2 diabetes mellitus. METHODS This study included 83 type 2 diabetes mellitus patients and 161 controls that were recruited from male employees who received annual health check-ups between 2005 and 2007. The serum HSP60 levels were measured using the ELISA method. RESULTS Because the HSP60 levels were not detectable (<3.125 ng/mL) in 48.0% of the study subjects, HSP60 levels were divided into two categories (detectable or undetectable). A logistic regression analysis showed that the subjects in the undetectable had a 2.03 times higher risk of diabetes mellitus than those in the detectable after adjustment for age, BMI and rate of hypertension medication. CONCLUSIONS This study was the first epidemiological study to demonstrate an association between type 2 diabetes mellitus and HSP60, thus suggesting that HSP60 may play an important role in the type 2 diabetes mellitus pathology.

Abstract
The purpose of this study is to evaluate the role of diffusion-weighted imaging (DWI) in combination with T(1) and T(2) weighted MRI for the characterisation of renal carcinoma. The institutional review board approved the study protocols and waived informed consent from all of the patients. 47 patients (32 male and 15 female; age range, 21-85 years; median age, 65 years) who had suspected renal lesions on abdominal CT underwent MRI for further evaluation and characterisation of the lesions from April 2005 to August 2007 in our university hospital. A region of interest was drawn around the tumour area on apparent diffusion coefficient (ADC) maps. Final diagnosis was confirmed by histological examination of surgical specimens from all patients. The ADC value was significantly higher in renal cell carcinoma (RCC) than in transitional cell carcinoma (2.71+/-2.35 x 10(-3) mm(2) s(-1) vs 1.61+/-0.80 x 10(-3) mm(2) s(-1); p = 0.022). While analysing the histological subtypes of RCC, a significant difference in ADC values between clear cell carcinoma and non-clear cell carcinoma was found (1.59+/-0.55 x 10(-3) mm(2) s(-1) vs 6.72+/-1.85 x 10(-3) mm(2) s(-1); p = 0.0004). Similarly, ADC values of RCC revealed a significant difference between positive and negative metastatic lesions (1.06+/-0.38 x 10(-3) mm(2) s(-1) vs 3.02+/-2.44 x 10(-3) mm(2) s(-1); p = 0.0004), whereas intensity on T(1) and T(2) weighted imaging did not reach statistical significance. In conclusion, DWI has clinical value in the characterisation of renal carcinomas and could be applied in clinical practice for their management.

Abstract
The presence of a macroscopic phase separation between the superconducting and magnetic phases in CaFe1-xCoxAsF is demonstrated by muon spin rotation measurements conducted across their phase boundaries (x=0.05-0.15). The magnetic phase tends to retain the high transition temperature (Tm>Tc), while Co doping induces strong randomness. The volumetric fraction of the superconducting phase is nearly proportional to the Co content x with a constant superfluid density. These observations suggest the formation of superconducting "islands" (or domains) associated with Co ions in the Fe2As2 layers, indicating a very short coherence length.

Abstract
PURPOSE To investigate possible involvement of chymase and angiotensin-converting enzyme (ACE) in the pathogenesis of vitreoretinal diseases, both of which are related to the production of angiotensin II. METHODS We measured chymase and ACE activities in the vitreous in the 54 affected eyes of 54 patients who had undergone vitreous surgery for idiopathic macular holes (MH, n = 14), proliferative diabetic retinopathy (PDR, n = 14), idiopathic epiretinal membranes (ERM, n = 13), and rhegmatogenous retinal detachment (RRD, n = 13). RESULTS Chymase activities in the vitreous from patients with MH, PDR, ERM, and RRD were 1.87 +/- 0.53, 0.06 +/- 0.04, 0.40 +/- 0.12, and 0.08 +/- 0.03 (mean +/- SE) mU/mg protein, respectively, and ACE activities in the vitreous humor were 0.18 +/- 0.09, 0.30 +/- 0.07, 0.01 +/- 0.01, and 0.03 +/- 0.02 (mean +/- SE) mU/mg protein, respectively. Chymase activity was significantly elevated in MH among these diseases (p < 0.01, Scheffe), and ACE was significantly activated in PDR compared to ERM and RRD (p < 0.05, Scheffe). CONCLUSIONS Our results suggest that two different angiotensin II generating systems are activated in human vitreous humor; an increased activity of chymase may play a possible role in the formation of macular holes.

Abstract
e14574 Background: Nimotuzumab, a humanized IgG1 monoclonal antibody targeting EGFR, has been used in head & neck cancer or malignant glioma outside Japan, and MTD including severe skin rash were not observed up to 800mg/body. This phase I study of nimotuzumab was conducted to investigate the safety profile, MTD, DLT, PK, human antibody against nimotuzumab (HAHA) in Japanese patients (pts), and PD analysis (activation of EGFR, Akt, MAPK, Ki67) was done. Methods: Pts with advanced solid tumors having no available standard therapy were enrolled. Nimotuzumab was given intravenously at dose levels of nimotumumab 100, 200 and 400mg/body, weekly. Blood, skin samples before treatment and after 4th infusion and pre-treatment tumor were collected for PD analysis. Results: 4 pts were enrolled in each level (total 12 pts). Pt characteristics were M/F 5/7, median age 57 years, ECOG PS 0/1 7/5. No grade 3 or 4 toxicities and no DLT were observed, and MTD was not determined. The major adverse event was grade 1 or 2 skin rash (58%, 7/12). Neither infusion reaction nor HAHA was observed. AUC0-inf, Cmax and t1/2 increased and CL deceased by dose dependent manner, indicating nonlinear PK characteristic. SD and PD were observed in 8 patients (67%) and4 patients (33%), without objective responses. Median time to progression was 4 months. Time to progression seemed to be longer in the pts with amplified gene copy number of EGFR though the number of pts was limited. Conclusions: Weekly infusion of nimotuzumab was well tolerated up to 400 mg/body in Japanese pts. A correlation between anti-tumor activity and EGFR amplification was speculated. Additional PD analysis is currently ongoing. No significant financial relationships to disclose.

Abstract
8059 Background: AMR is a totally synthetic 9-aminoanthracycline and a novel topoisomerase II inhibitor. AMR has shown promising clinical activity for advanced NSCLC as well as SCLC. This trial was conducted to evaluate the efficacy and safety of AMR for pts with NSCLC previously treated with platinum-based chemotherapy. Methods: Eligible pts had a performance status 0 to 1, previous treatment with one platinum-based chemotherapy for advanced NSCLC, and adequate organ function. Pts received AMR 40 mg/m2 intravenously on days 1–3 every 3 weeks. The primary endpoint was the objective response rate, which determined the sample size based on an optimal two-stage design. With the target activity level of 18% and the lowest response rate of interest set at 5%, 60 eligible patients were required with a 90% power to accept the hypothesis and a 5% significance level to reject the hypothesis. Results: Sixty-one pts (median age, 63 years; range 51–74 years) were enrolled. The median treatment cycles were 2 (range, 1–15). No complete responses and 7 partial responses were observed, giving an overall response rate of 11.5% (95% CI, 4.7–22.2%). Twenty patients (32.8%) had stable disease and 34 patients (55.7%) had progressive disease as the best response. The overall disease control rate (complete response + partial response + stable disease) was thus 44.3% (95% CI, 31.5–57.6%). The median overall survival and 1-year survival rate were 8.5 months and 32.0%, respectively. Grade 3/4 hematological toxicities were neutropenia (82%), anemia (27.9%) and thrombocytopenia (24.6%). Grade 3/4 non-hematological toxicities were anorexia (9.8%), febrile neutropenia (29.5%) and pneumonitis (1.6%). No treatment-related death and cardiac toxicity were observed. Conclusions: AMR exhibits significant activity with manageable toxicities as second-line therapy for advanced NSCLC. [Table: see text]

Abstract
e22032 Background: The most active gemcitabine uptake has been found via the human equilibrative nucleoside transporter 1 (hENT1). This study was to explore the prognostic impact of the hENT1 on response and survival in Non-small lung cancer (NSCLC) patients treated with gemcitabine-containing chemotherapy. Methods: We developed polyclonal antibody for hENT1. Then we stained hENT1 expression by immunohistochemical analysis in 24 biopsy samples of NSCLC which was formaline-fixed, paraffin- embedded tissues. We were treated with gemcitabine alone or gemcitabine-containing chemotherapy until third-line regimen. Results: They comprised 16 males and 8 females with a median age of 63 years (range 45–82 years). Seventeen patients had adenocarcinomas, six had squamous-cell carcinomas, and one had a large-cell carcinoma. All patients were treated with gemcitabine- containing chemotherapy, with 9, 12, and 3 patients receiving this as a first-, second-, and third-line therapy, respectively. The hENT1-positive staining in NSCLC samples was significantly associated with response to gemcitabine-containing chemotherapy (Fisher's exact test, P<0.05). Responses to gemcitabine-containing chemotherapy were evident in none of the seven patients with no hENT1 expression. Further 3 years survival differed by hENT1 staining: 714 days for hENT1-positive, 316 days for hENT1-negative (HR 2.86; 95%CI 1.13–15.16, P<0.05). Conclusions: While there are some determinants for gemcitabine sensitivity, hENT1 expression may be a predictive maker for the response and survival to gemcitabine-containing chemotherapy in NSCLC. No significant financial relationships to disclose.

Abstract
4579 Background: Biliary tract cancers (BTC) are not common but increasing in the US and Europe, and more prevalent in South America and Asia including Japan. Gemcitabine (G) and cisplatin (C) are now deemed as key drugs based on the accumulated literature. This is the first study to compare GC combination with G alone in Japan, even though one phase 3 trial (ABC-02) is ongoing in UK. Methods: 84 Japanese pts, aged ≥ 20 years, with histologically or cytologically confirmed advanced BTC, Performance Status 0 - 1, with adequate bone-marrow, hepatic and renal function were randomized. 83 pts received either C 25 mg/m2 plus G 1000 mg/m2 on days 1, and 8 of each 21-day cycle (GC-arm) or G 1000 mg/m2 on days 1, 8 and 15 of each 28-day cycle (G-arm). Treatments were repeated up to a maximum of 16 cycles of GC or 12 of G until disease progression or unacceptable toxicity occurred. Tumor response was evaluated using RECIST criteria by an independent review committee. The primary end-point of the study was 1- year survival rate. Safety, response rate, duration of progression-free survival were also evaluated. Results: A total of 83 pts (19 extrahepatic bile duct cancer, 28 intrahepatic bile duct cancer, 32 gallbladder cancer and 4 ampullary carcinoma) were eligible for the study protocol defined analysis set (Full Analysis Set, FAS); GC-arm n=41 and G-arm n=42. Baseline characteristics were similar between the two arms: median ages were 65.0 vs 66.5, females were 56.1 vs 50.0%. All pts completed at least one cycle of therapy, yielding a total of 247 cycles (median 6) in GC vs 203 (median 4) in G. The overall response rates were 19.5% (95% CI: 8.8, 34.9) vs 11.9 (95% CI: 4.0, 25.6). The results on survival will be determined and presented at the meeting. The most commonly reported grade 3 or 4 toxicities were: neutropenia (56.1 vs 38.1%), thrombocytopenia (39.0 vs 7.1%), leukopenia (29.3 vs 19.0%), hemoglobin decrease (36.6 vs 16.7%) and γ-GTP increase (29.3 vs 35.7%). Grade 3 acute renal failure was reported in 1 pt on GC. Conclusions: The combination therapy of GC would be an effective and well-tolerated chemotherapy regimen for Japanese pts with advanced BTC.

Abstract
e14630 Background: SU is an oral, multitargeted tyrosine kinase inhibitor of VEGFRs, PDGFRs, KIT, RET, FLT3, and CSR-1, and shows antitumor activities in several types of solid malignancies. Non-small-cell lung cancer (NSCLC) xenograft data indicate SU enhanced the antitumor activity of Pem. This phase I study was designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of combination therapy with the oral SU and Pem for Japanese patients with advanced ST. Methods: Pts with ST refractory to standard therapy were randomly assigned to receive either oral SU 50 mg/day for 2 weeks followed by 1 week rest (Schedule 2/1, S-2/1) or SU 37.5 mg continuous daily dose (CDD). Fixed-dose Pem (500mg/m2 IV) was administered on day1 every 21 days. A standard “3+3” design was employed in both treatment schedules and treatment continued until tumor progression or dose-limiting toxicity (DLT) was observed. Results: A total of 12 pts (med. age 63 years, range 49–69; 10 Male/ 2 Female) have been enrolled (6 pts in the S-2/1 arm and 6 pts in the CDD arm). The most common cancer is NSCLC (9 pts, 75%). All patients completed their first cycle for DLT evaluation, and no DLTs were observed in either treatment arm. The most common toxicities were fatigue (n=8), anorexia (n=6), and thrombocytopenia (n=12). Treatment-related ≥ grade 3 adverse events (AEs) included fatigue (n=1), hypertension (n=1), neutropenia (n=4), leucopenia (n=3), thrombocytopenia (n=2), lymphopenia (n=2), and increased ALT (n=1). Three pts (S-2/1: 2, CDD: 1) required dose reduction of SU due to G3 toxicities. All toxicities were clinically manageable and reversible. One pt with NSCLC had a documented PR with cavity formation inside the tumor. Conclusions: SU 37.5 mg/day (CDD schedule) plus Pem 500mg/m2 every 21 days, and SU 50 mg/day (S-2/1 schedule) plus Pem 500mg/m2 every 21 days were well tolerated and associated with encouraging antitumor activity.

Abstract
AIMS/HYPOTHESIS The WFS1 gene encodes an endoplasmic reticulum (ER) membrane-embedded protein called Wolfram syndrome 1 protein, homozygous mutations of which cause selective beta cell loss in humans. The function(s) of this protein and the mechanism by which the mutations of this gene cause beta cell death are still not fully understood. We hypothesised that increased insulin demand as a result of obesity/insulin resistance causes ER stress in pancreatic beta cells, thereby promoting beta cell death. METHODS We studied the effect of breeding Wfs1 ( -/- ) mice on a C57BL/6J background with mild obesity and insulin resistance, by introducing the agouti lethal yellow mutation (A ( y ) /a). We also treated the mice with pioglitazone. RESULTS Wfs1 ( -/- ) mice bred on a C57BL/6J background rarely develop overt diabetes by 24 weeks of age, showing only mild beta cell loss. However, Wfs1 ( -/- ) A ( y ) /a mice developed selective beta cell loss and severe insulin-deficient diabetes as early as 8 weeks. This beta cell loss was due to apoptosis. In Wfs1 ( +/+ ) A ( y ) /a islets, levels of ER chaperone immunoglobulin-binding protein (BiP)/78 kDa glucose-regulated protein (GRP78) and phosphorylation of eukaryotic translation initiation factor 2, subunit alpha (eIF2alpha) apparently increased. Levels of both were further increased in Wfs1 ( -/- ) A ( y ) /a murine islets. Electron micrography revealed markedly dilated ERs in Wfs1 (-/-) A ( y ) /a murine beta cells. Interestingly, pioglitazone treatment protected beta cells from apoptosis and almost completely prevented diabetes development. CONCLUSIONS/INTERPRETATION Wfs1-deficient beta cells are susceptible to ER stress. Increased insulin demand prompts apoptosis in such cells in vivo. Pioglitazone, remarkably, suppresses this process and prevents diabetes. As common WFS1 gene variants have recently been shown to confer a risk of type 2 diabetes, our findings may be relevant to the gradual but progressive loss of beta cells in type 2 diabetes.

Abstract
BACKGROUND/AIMS Management of patients with recurrent intrahepatic cholangiocarcinoma (ICC) following surgical resection is difficult, and surgical resection is rarely indicated. We retrospectively reviewed patients with recurrent intrahepatic cholangiocarcinoma. METHODOLOGY Between April 1998 and March 2007, 57 consecutive patients with ICC underwent surgical resection. Mode of recurrence and treatment of recurrent tumors, especially surgical resection for these tumors, in patients with cancer recurrence were evaluated. RESULTS 37 (65%) patients experienced tumor recurrence. Out of these patients, 24 underwent some type of cancer-directed therapy, including 9 patients (24%) for whom surgical resection was attempted: the latter included 4 hepatic resections, 2 pulmonary resections, 2 tumor resections, and 1 gastric resection. For 6 patients with recurrent tumor in the liver or the lung, microscopic complete resection was achieved, while incomplete resection was resulted in the remaining 3 patients. No postoperative mortality was encountered. Among patients with complete resection, 3 are alive without disease 32, 39 and 77 months after the second operation, one has lived with disease for 13 months, and 2 died of disease after 22 and 26 months. No significant difference in overall survival was observed between patients undergoing primary and second surgical resections, calculated from the primary and the second operations, respectively. CONCLUSIONS Repeated surgical resection for recurrent ICC can be performed with acceptable morbidity, and affords selected patients a chance for long-term survival.

Abstract
Kinetic magnetic resonance images (kMRIs) of 587 lumbar and 459 cervical spines of symptomatic patients in axially loaded, upright neutral (0 degrees), flexion (40 degrees), and extension (-20 degrees) positions were evaluated. Imaging took 10 to 12 minutes to complete in each position. Cervical kinematics were significantly affected by intervertebral disc degeneration, cervical cord compression, and sagittal alignment of the cervical spine. kMRI was effective in diagnosing lumbar disc herniations that are often missed using conventional MRI. kMRI is effective for diagnosing, evaluating, and managing degenerative disease or injury within the spine.

Abstract
ABO-incompatible kidney transplantation has become a popular alternative to kidney transplantation in Japan because of the severe shortage of cadaveric donors. In our institution, 21 cases of ABO-incompatible kidney transplantation were performed from April 2004, to October 2007. Recipient age was 42.8 +/- 14.5 years old; there were 9 men and 12 women. Duration of hemodialysis was 1,914 +/- 2,343 days. Donor operation was performed using a complete laparoscopic procedure. Recipient's splenectomy was performed using a hand-assisted laparoscopic procedure and kidney transplantation was performed with a standard method using an extraperitoneal approach. Pretransplant immunosuppressive protocol includes an administration of mycophenolate mofetil, tacrolimus, predonisolone, splenectomy, double filtration plasmapheresis (DFPP), and plasma exchange (PE). All patients showed an immediate graft function and their serum creatinine levels promptly decreased to 1.48 +/- 0.99 mg/dL on day 7 and 1.21 +/- 0.72 mg/dL on day 30. Both immunoglobulin (Ig)M and IgG titers were maintained at much lower levels for 7 days after transplantation in all patients. Cytomegalovirus antigenemia was observed in 11 patients (52.4%). One patient (4.8%) developed a Pneumocystis Carinii pneumonia and the formation of lymphocele was observed in one patient (4.8%). Total patient survival at 3 years was 95.2%, and graft survival at 3 years was 90.5%, which were almost equal to those in the patients who underwent ABO-matched, compatible kidney transplantation.
