Abstract
We present measurements of the cross section and double-helicity asymmetry A_{LL} of direct-photon production in p[over →]+p[over →] collisions at sqrt[s]=510 GeV. The measurements have been performed at midrapidity (|η|<0.25) with the PHENIX detector at the Relativistic Heavy Ion Collider. At relativistic energies, direct photons are dominantly produced from the initial quark-gluon hard scattering and do not interact via the strong force at leading order. Therefore, at sqrt[s]=510 GeV, where leading-order-effects dominate, these measurements provide clean and direct access to the gluon helicity in the polarized proton in the gluon-momentum-fraction range 0.02<x<0.08, with direct sensitivity to the sign of the gluon contribution.

Abstract
This paper describes a method to estimate the direction from which the signal molecule reaches the sensor by using living cells. In this context, biohybrid sensors that utilize a sophisticated sensing system of cells can potentially offer high levels of chemical-detection sensitivity and selectivity. However, biohybrid-sensor-based chemical-source-direction estimation has not received research attention because the cellular response to chemicals has not been examined in the context of directional information. In our approach, we fabricated a device that can limit the interface between the cell-laden hydrogel and the chemical solution of interest to enhance the time difference over which the chemical solution reaches the cells. Chemical detection by cells that express specific receptors is reflected as the fluorescence of the calcium indicator within the cells. Our device has eight chambers that each house 3D cell-laden collagen hydrogels facing circularly outward. The device also works as a cover to prevent chemicals from permeating the hydrogel from above. In our study, by observing the time course of the fluorescence emission of each chamber, we were able to successfully estimate the chemical-source direction within an error range of 7–13°. Our results suggest that a combination of microstructure devices embedded with living cells can be used to exploit cell functionalities to yield chemical-source directional information.

Abstract
We investigated the phylogenetic diversity, localisation and metabolism of an uncultured bacterial clade, Termite Group 2 (TG2), or ZB3, in the termite gut, which belongs to the candidate phylum 'Margulisbacteria'. We performed 16S rRNA amplicon sequencing analysis and detected TG2/ZB3 sequences in 40 out of 72 termite and cockroach species, which exclusively constituted a monophyletic cluster in the TG2/ZB3 clade. Fluorescence in situ hybridisation analysis in lower termites revealed that these bacteria are specifically attached to ectosymbiotic spirochetes of oxymonad gut protists. Draft genomes of four TG2/ZB3 phylotypes from a small number of bacterial cells were reconstructed, and functional genome analysis suggested that these bacteria hydrolyse and ferment cellulose/cellobiose to H2, CO2, acetate and ethanol. We also assembled a draft genome for a partner Treponema spirochete and found that it encoded genes for reductive acetogenesis from H2 and CO2. We hypothesise that the TG2/ZB3 bacteria we report here are commensal or mutualistic symbionts of the spirochetes, exploiting the spirochetes as H2 sinks. For these bacteria, we propose a novel genus, 'Candidatus Termititenax', which represents a hitherto uncharacterised class-level clade in 'Margulisbacteria'. Our findings add another layer, i.e., cellular association between bacteria, to the multi-layered symbiotic system in the termite gut.

Abstract
Termite guts harbor diverse yet-uncultured bacteria, including a non-photosynthetic cyanobacterial group, the class "Melainabacteria". We herein reported the phylogenetic diversity of "Melainabacteria" in the guts of diverse termites and conducted a single-cell genome analysis of a melainabacterium obtained from the gut of the termite Termes propinquus. We performed amplicon sequencing of 16S rRNA genes from the guts of 60 termite and eight cockroach species, and detected melainabacterial sequences in 48 out of the 68 insect species, albeit with low abundances (0.02-1.90%). Most of the melainabacterial sequences obtained were assigned to the order "Gastranaerophilales" and appeared to form clusters unique to termites and cockroaches. A single-cell genome of a melainabacterium, designated phylotype Tpq-Mel-01, was obtained using a fluorescence-activated cell sorter and whole genome amplification. The genome shared basic features with other melainabacterial genomes previously reconstructed from the metagenomes of human and koala feces. The bacterium had a small genome (~1.6 Mb) and possessed fermentative pathways possibly using sugars and chitobiose as carbon and energy sources, while the pathways for photosynthesis and carbon fixation were not found. The genome contained genes for flagellar components and chemotaxis; therefore, the bacterium is likely motile. A fluorescence in situ hybridization analysis showed that the cells of Tpq-Mel-01 and/or its close relatives are short rods with the dimensions of 1.1±0.2 μm by 0.5±0.1 μm; for these bacteria, we propose the novel species, "Candidatus Gastranaerophilus termiticola". Our results provide fundamental information on "Melainabacteria" in the termite gut and expand our knowledge on this underrepresented, non-photosynthetic cyanobacterial group.

Abstract
“Candidatus Endomicrobium trichonymphae” (Bacteria; Elusimicrobia) is an obligate intracellular symbiont of the cellulolytic protist genus Trichonympha in the termite gut. A previous genome analysis of “Ca. Endomicrobium trichonymphae” phylotype Rs-D17 (genomovar Ri2008), obtained from a Trichonympha agilis cell in the gut of the termite Reticulitermes speratus, revealed that its genome is small (1.1 Mb) and contains many pseudogenes; it is in the course of reductive genome evolution. Here we report the complete genome sequence of another Rs-D17 genomovar, Ti2015, obtained from a different T. agilis cell present in an R. speratus gut. These two genomovars share most intact protein-coding genes and pseudogenes, showing 98.6% chromosome sequence similarity. However, characteristic differences were found in their defense systems, which comprised restriction-modification and CRISPR/Cas systems. The repertoire of intact restriction-modification systems differed between the genomovars, and two of the three CRISPR/Cas loci in genomovar Ri2008 are pseudogenized or missing in genomovar Ti2015. These results suggest relaxed selection pressure for maintaining these defense systems. Nevertheless, the remaining CRISPR/Cas system in each genomovar appears to be active; none of the “spacer” sequences (112 in Ri2008 and 128 in Ti2015) were shared whereas the “repeat” sequences were identical. Furthermore, we obtained draft genomes of three additional endosymbiotic Endomicrobium phylotypes from different host protist species, and discovered multiple, intact CRISPR/Cas systems in each genome. Collectively, unlike bacteriome endosymbionts in insects, the Endomicrobium endosymbionts of termite-gut protists appear to require defense against foreign DNA, although the required level of defense has likely been reduced during their intracellular lives.

Abstract
Abstract
Background: There is a high risk of under-reporting subjective toxicities by physicians, even when collected prospectively in clinical trials. It has been recommended to include patient reported measures regarding symptoms in prospective clinical comparative effectiveness trials. However, there have been few reports of agreement in endocrine related symptoms between patient and physician reporting.
Patients and Method: The National Surgical Adjuvant Study of Breast Cancer 06 (N-SAS BC 06) is a multicenter, randomized clinical trial of postmenopausal, hormone receptor-positive breast cancer patients, with a two-stage (preoperative and postoperative) enrollment, and intervention. The primary aim was to evaluate the need for adjuvant chemotherapy in the treatment of postmenopausal breast cancer patients who responded to neoadjuvant treatment with Letrozole (LET) for 24-28 weeks. After surgery, responders were randomized into two arms receiving either chemotherapy plus LET, or LET alone. The primary endpoint was disease-free survival, and the secondary endpoints included adverse events, quality of life and health economic evaluation. This study enrolled 497 subjects from the N-SAS BC 06 who were evaluated by Patient Reported Outcomes (PROs). The concordance rate between Clinician Reported Outcomes (CROs) and PROs in their endocrine symptoms during neoadjuvant endocrine therapy was examined. Symptoms were collected prospectively by physicians using the Common Toxicity Criteria for Adverse Events at enrollment, i.e., baseline, and 4 and 16 weeks after starting neoadjuvant LET. Patients also completed the FACT-G (General), B (Breast), ES (Endocrine Symptoms), and HADS. The endocrine symptoms according to the PROs, included nausea, hot flushes, cold sweats, headaches, and HADS-Depression score. In FACT, "Not at all" was used to express the absence of the symptoms, and "A little bit", "Some-what", "Quite a bit", and "Very much" were used to express the presence of symptoms. The HADS-Depression score threshold was 10/11. According to the CROs, grade 0 was defined as the absence of symptoms and grade 1 or more was defined as the presence of symptoms. Cohen's kappa was used to determine the concordance between CROs and PROs. The sensitivity of CROs was also calculated.
Results: The calculated point estimates of Cohen's kappa at Weeks 4 and 16 after starting neoadjuvant LET were 0.12 and 0.01 for nausea, 0.16 and 0.18 for hot flushes, 0.12 and 0.09 for cold sweats, 0.03 and 0.02 for headaches, and 0.11 and 0.11 for dysthymia/depression, respectively; the concordance was quite low. The sensitivity of CROs at Weeks 4 and 16 after starting neoadjuvant LET was 0.07 and 0.03 for nausea, 0.16 and 0.17 for hot flushes, 0.1 and 0.08 for cold sweats, 0.03 and 0.03 for headaches, and 0.11 and 0.1 for dysthymia/depression, respectively; the sensitivity was quite low.
Conclusion: This study showed that there were big differences between CROs and PROs in endocrine symptoms associated with endocrine therapy for breast cancer and that physicians could not obtain sufficient information on the endocrine symptoms. It is recommended that PROs be used to evaluate adverse events caused by endocrine therapy.

Abstract
Termites consume an estimated 3–7 billion tonnes of lignocellulose annually, a role in nature which is unique for a single order of invertebrates. Their food is digested with the help of microbial symbionts, a relationship that has been recognized for 200 years and actively researched for at least a century. Although DNA- and RNA-based approaches have greatly refined the details of the process and the identities of the participants, the allocation of roles in space and time remains unclear. To resolve this issue, a pioneer study is reported using metabolomics to chart the in situ catabolism of 13C-cellulose fed to the dampwood species Hodotermopsis sjostedti. The results confirm that the secretion of endogenous cellulases by the host may be significant to the digestive process and indicate that a major contribution by hindgut bacteria is phosphorolysis of cellodextrins or cellobiose. This study provides evidence that essential amino acid acquisition by termites occurs following the lysis of microbial tissue obtained via proctodaeal trophallaxis.

Abstract
OBJECTIVE To evaluate the role of diffusion-weighted MRI (DW-MRI) as an imaging biomarker for upper urinary tract cancer (UUTC) that has already metastasized or will metastasize soon. METHODS 61 patients clinically diagnosed with UUTC were prospectively enrolled in this study. All the patients underwent MRI, including DW-MRI, prior to any interventions. Correlations between apparent diffusion coefficient (ADC) and other clinicopathological variables, including metastasis-free survival, were analysed. RESULTS Median follow-up period was 938 days. Of the 61 patients, 12 had any metastases at the initial diagnosis. 11 patients developed metastases during the follow-up period. These 23 patients were categorized as "Metastatic". Of the remaining 38 patients, 35 with a follow-up period longer than 400 days were categorized as "Localized". ADC was significantly lower in the Metastatic category than in the Localized (p = 0.0002) category. Multivariate analysis of pre-operative variables identified ADC (cut-off value, 1.08 × 10(-3) mm(2) s(-1)) and clinical T stage based on T2 weighted MRI as an independent predictive factor of metastatic UUTC. 46 patients without any metastases during the initial diagnosis were stratified into a high-risk group (16 patients with low ADC and clinical T3-4) and a low-risk group (30 patients with high ADC or clinical Ta-2). The 3-year metastasis-free survivals were 45% and 93%, respectively. CONCLUSION In the current study, UUTC with lower ADC value is more likely to have metastatic potential. Incorporating ADC with clinical T stage helps to differentiate metastatic UUTC at the initial diagnosis. ADVANCES IN KNOWLEDGE DW-MRI is a potential imaging biomarker reflecting metastatic propensity of UUTC.

Abstract
Mutualism is ubiquitous in nature but is known to be intrinsically vulnerable with regard to both population dynamics and evolution. Synthetic ecology has indicated that it is feasible for organisms to establish novel mutualism merely through encountering each other by showing that it is feasible to construct synthetic mutualism between organisms. However, bacteria-eukaryote mutualism, which is ecologically important, has not yet been constructed. In this study, we synthetically constructed mutualism between a bacterium and a eukaryote by using two model organisms. We mixed a bacterium, Escherichia coli (a genetically engineered glutamine auxotroph), and an amoeba, Dictyostelium discoideum, in 14 sets of conditions in which each species could not grow in monoculture but potentially could grow in coculture. Under a single condition in which the bacterium and amoeba mutually compensated for the lack of required nutrients (lipoic acid and glutamine, respectively), both species grew continuously through several subcultures, essentially establishing mutualism. Our results shed light on the establishment of bacteria-eukaryote mutualism and indicate that a bacterium and eukaryote pair in nature also has a non-negligible possibility of establishing novel mutualism if the organisms are potentially mutualistic.

Abstract
Signal transducer and activators of transcription (STAT) gene, suppressors of cytokine signaling (SOCS) has been isolated from kuruma shrimp, Marsupenaeus japonicus and characterized. The kuruma shrimp STAT (MjSTAT) cDNA was composed of 2901 bp consisting of 801 amino acid residues which includes a protein interaction domain, all alpha domain, DNA binding domain and SH2 domain. Homology analysis of MjSTAT showed 94.1% and 34.0% identities with Penaeus monodon STAT (PmSTAT) and Drosophila melanogaster STAT92E (DmSTAT), respectively. The kuruma shrimp SOCS (MjSOCS) cDNA was composed of 1675 bp consisting of 342 amino acid residues including a SH2 domain and C-terminal SOCS domain. Homology analysis of MjSOCS showed 52.6% and 21.3% identities with Chinese mitten crab (Eriocheir sinensis) SOCS2 and fruit fly (D. melanogaster) SOCS44A, respectively. The MjSTAT and MjSOCS genes are constitutively expressed in the muscle, stomach, brain and gill of kuruma shrimp. In lymphoid organ cells, an enhanced expression of both MjSTAT and MjSOCS genes are observed following stimulation with peptidoglycan and polycytidylic acid. These observations suggest that MjSTAT and MjSOCS might play a major role in the innate immune defense of kuruma shrimp. The discovery of JAK/STAT signaling pathway in shrimp will allow a complete and concrete understanding of shrimp cytokine signaling.

Abstract
111 Background: There is no perfect cohort in which nomograms are developed because no biopsy method can detect all cancers. To minimize this inherent verification bias, having a cohort with fewer false negative cases is advantageous. Based on a cohort examined with three-dimensional (3D) extended biopsy protocol, we developed a novel nomogram for diagnosis of prostate cancer on repeat biopsy. Methods: Of 4,074 consecutive male patients undergoing prostate biopsy at our institutions between 2000 and 2009, 775 men with at least one previous negative biopsy underwent repeat biopsy with 3D protocol. Men with previous atypical glands or atypical small acinar proliferation and/or without available prostate-specific antigen (PSA) kinetics information were excluded. The remaining 515 men constituted the study cohort. We developed a logistic regression-based nomogram with 70% of the cohort selected randomly; we validated it with the remaining 30%. Predictive accuracy and performance characteristics were assessed using the area under the receiver operating characteristic curve (AUC) and calibration plots, respectively. The threshold probability was evaluated with decision curve analysis. Results: We developed a novel repeat biopsy nomogram incorporating age, free to total PSA ratio, prostate volume, history of previous extended biopsy, and PSA doubling time. Validation confirmed predictive accuracy with an AUC value of 0.791. Calibration plots showed good agreement. The decision curve of the nomogram was superior to the decision curve of biopsying all men in a range of threshold probability over 0.15. At the threshold of 0.2, the number of unnecessary biopsies could be reduced by 10 per 100, without missing PCa. Conclusions: We developed a novel repeat biopsy nomogram based on a cohort examined with 3D extended biopsy. This repeat biopsy nomogram is clinically beneficial, saving a substantial number of unnecessary biopsies. No significant financial relationships to disclose.

Abstract
159 Background: Treatment with an LH-RH agonist is a standard alternative to surgical castration for prostate cancer patients. The serum testosterone level is kept at castrate levels continuously during LH-RH agonist therapy in almost all patients (Fujii Y, BJU Int 2008). LH- RH agonists, however, are more expensive than surgical castration, with drugs costing between US $300 and $500 per month in Japan. Recent studies suggest that 3-monthly formulations of LH-RH agonists suppress the serum testosterone levels far longer than the 3-month dosing interval. Methods: A total of 43 Japanese patients with prostate cancer who were treated with 3-monthly LH-RH agonists (23 with 11.25mg leuprolide, and 20 with 10.8 mg goserelin) for one year or longer and whose testosterone levels were kept at castrate level (defined as < 50 ng/dL) were entered into this prospective, longitudinal study. After entry, the 43 men received the same 3-monthly LH-RH agonists at 6-month intervals, and had serum LH and testosterone tests performed at 3-month intervals. Bicalutamide was combined with the LH-RH agonists in 12 of the patients. Results: At entry, median patient age was 74 years (range 59 to 89), median duration of LH-RH agonists treatment was 26 months (12 to 125), and median LH and testosterone levels were <10 ng/dL (<10 to 60) and 5 ng/dL (<5 to 18), respectively. The 43 patients received a total of 162 administrations (median 5, range 1 to 6) of the LH-RH agonists at 6-month intervals, and had a total 335 hormonal tests (median 10, range 2 to12) performed during the median followup period of 30 months. Serum LH and testosterone levels were kept suppressed during the treatment. Of the 43 patients, two had serum testosterone just above the castrate level (54 and 56 ng/dL) once each among their 12 and 8 hormonal assays, respectively. Conclusions: Administration of 3-monthly LH-RH agonists, either leuprolide or goserelin, at 6-month intervals could maintain the castrate level of serum testosterone at least in Japanese prostate cancer patients who have received LH-RH agonists treatment for one year or longer. No significant financial relationships to disclose.

Abstract
385 Background: Indication of nephron sparing surgery (NSS) for renal cell carcinoma (RCC) has been extending, as NSS can be considered for not only cT1a but also cT1b tumors. However, some cT1 diseases have pathological perinephric or renal sinus fat invasion. It is useful to know the probability of the presence of fat invasion before surgery, but diagnostic ability of imaging studies such as CT for predicting pT3a disease is limited. Therefore, estimation of the risk for pT3a disease in cT1 RCC patients could be helpful. C-reactive protein (CRP) has been shown to be a strong prognostic factor in RCC patients, reflecting tumor aggressiveness. We evaluated the predictive ability of preoperative CRP for pT3a disease in cT1N0M0 RCC patients. Methods: Of consecutive 386 patients treated with radical nephrectomy for cT1a-bN0M0 RCC, 82 were excluded due to hemodialysis, inflammatory disease, bilateral synchronous renal tumors, synchronous other malignant disease or loss of each data. The remaining 304 patients constituted the current study cohort. Cut off point of CRP was 3 mg/L. Associations were analyzed between pT3a and preoperative factors including age, sex, BMI, laterality, tumor size, CRP, hemoglobin, platelet, LDH, ALP, calcium and albumin. We developed a multivariate model for predicting pT3a disease in cT1 RCC. Results: Of the 304 patients, 28 (9%) had pT3a disease. Of 43 patients with elevated CRP level, 10 (23%) had pT3a disease. In contrast, of the remaining 261 patients with non-elevated CRP level, 18 (7%) had (p=0.002). Univariate and then multivariate analyses identified age (p=0.021), tumor size (p=0.007), and CRP (p=0.024) as independent and significant predictors for pT3a disease. Incorporating these three factors, we developed a predictive model for pT3a disease with predictive accuracy of area under the ROC curve of 0.772. Conclusions: Preoperative CRP is an independent predictor for pT3a disease in cT1 RCC along with age and tumor size. The model could be useful to estimate the risk of the probability of fat invasion before surgery, especially NSS. No significant financial relationships to disclose.

Abstract
376 Background: Gasless single port retroperitoneal radical nephrectomy is minimally invasive, curative and cost effective operation which we have developed since 1998 (Eur Urol Suppl 2009; 8: 392), and covered by the Japanese universal insurance system from April, 2008. Patients necessitating dialysis are considered high risk operative candidates because of their multiple comorbidities. We compared surgical outcomes of dialysis patients with non-dialysis patients to evaluate this operation as treatment for high risk group. Methods: We reviewed 304 consecutive patients including 59 (19.4%) dialysis patients who underwent CO2 gasless single port retroperitoneal radical nephrectomy at our institute between 2000 and 2009. Complications within the first 30 days after the surgery were graded retrospectively according to the modified Clavien classification system. Patient demographics, operative outcomes, and complications were compared between dialysis and non-dialysis patients. Results: In all patients, the median patient age and body mass index were 60 years and 23.0 kg/m2. The median length of surgical incision, operative time (OT) and estimated blood loss (EBL) were 6.5 cm, 189 minutes and 214 mL, respectively. The transfusion rate was 3.3%. The intra and postoperative complication rate were 3.9% and 10.1%. Two grade 3a (ureteral obstruction, 1; diverticulitis, 1), three grade 3b (occlusion of peripheral hemodialysis shunt, 3) and two grade 4 (pulmonary embolism, 1; acute heart failure, 1) surgical complications occurred. In dialysis patients, the mean BMI was lower (20.4 vs. 23.3, p<0.0001), the mean OT was shorter (170 vs. 201 minutes, p<0.0001) and the mean EBL was lower (216 vs. 311mL, p<0.0001) than non-dialysis patients. There was no Clavien grade 3 or 4 surgical complications except dialysis access occlusion in dialysis patients. The average time to oral feeding and walking were equivalent, but possible discharge were longer in dialysis patients (4.3 vs. 3.4 days, p<0.0037). Conclusions: Our data supports the safety and feasibility of gasless single port retroperitoneal radical nephrectomy for dialysis patients. No significant financial relationships to disclose.

Abstract
99 Background: Focal therapy for prostate cancer could be a minimally invasive therapeutic option with the preservation of genitourinary function to reduce treatment associated complication under the appropriate selection of patients. We have reported the good predict ability to unilateral prostate cancer by extended prostate biopsy combined with transperineal and transrectal approaches (Eur Urol supple, 2009). Among the candidate ablative, brachytherapy which has been proved as a definitive therapy and applied worldwide has been thought to have potential for focal ablation due to its ability of dose and location adjustment by seed implantation under real-time monitoring. Based on the findings, focal therapy with hemiablation using I-125 seed implantation has been started in our instituion. The aim of study is to describe the initial experience of focal therapy for patients selected by extended biopsy and MRI findings. Methods: The eligible criteria for focal therapy to prostate cancer are as follows. Clinical stage is T2a or less. The positive cores of cancer are proven within unilateral lobe by extended prostate biopsy. There was no cancerous lesion in contralateral lobe by MRI. Gleason score in positive cores was 3 + 4 or less. Maximum cancer length was less than 5 mm. PSA value is less than 10 ng/mL. On the treatment, I-125 seeds were implanted to ablate the unilateral lobe with 160 Gy of the prescription dose. The protocol has been approved by the institutional ethics commit. Results: At present, 3 patients were enrolled in this study and underwent focal therapy with written informed consents. In all three cases, I-125 seeds implanted (number od seeds: 43, 39, and 37) to unilateral lobe without severe acute complication such as acute urinary retention. In one case that has been followed over 3months among the initial three cases, PSA values decreased to 2.07 mg/ml at 3 months after the seed implantation. Conclusions: To our knowledge, this is the first report about focal therapy by brachytherapy with hemiablative technique. In our initail experience, severe treatment associated complication has not been observed. No significant financial relationships to disclose.

Abstract
333 Background: As cytokines and targeted agents against advanced renal cell carcinoma (aRCC) are considered to achieve high stable disease (SD) rate rather than objective response (OR) by radiographic measurement, we often face the therapeutic dilemma in deciding whether to continue the ongoing treatment and when to change it. Therefore, other valid surrogate endpoints have been desired. We have previously demonstrated C-reactive protein (CRP) kinetics could predict prognosis of pts with aRCC (Eur Urol. 2009:1145-53). Methods: This study was performed on 56 pts with aRCC (metastatic: 54, unresectable: 2) enrolled in a phase II trial of interferon-alpha, cimetidine, COX-2 inhibitor and renin-angiotensin-system inhibitor (I-CCA; Cancer Sci. in press). CRP levels were measured at pretreatment, thereafter almost every visit. Pts were divided into 3 groups according to CRP kinetics. Pts whose pretreatment CRP levels were < 5 mg/l were assigned to nonelevated group. Pts whose pretreatment CRP levels were > 5 mg/l but normalized (< 5 mg/l) at least one time during I-CCA were assigned to normalized group. Pts whose CRP level never decreased to normal level were assigned to non-normalized group. Radiographic response was assessed by WHO criteria; survivals were estimated by Kaplan–Meier method and prognostic factors were assessed by Cox's proportional hazard model. Results: Median follow-up was 26 mo. An OR and clinical benefit rate to I-CCA were 20 and 64%, respectively. The median progression-free and overall survival (OS) was 12 and 45 mo, respectively. The median OS was 74, 83 and 13 mo in in non-elevated (n=26), normalized (n=16) and non-normalized (n=14) group, respectively (p<0.0001). Of the 25 pts achieving SD, CRP kinetics was independent prognostic factor for OS (p<0.0001). Of the pts whose pretreatment CRP was elevated, all pts achieving OR had CRP normalization and multivariate analysis revealed CRP normalization was independent prognostic factor for OS (p=0.0008), whereas achieving OR was not (p=0.19). Conclusions: CRP kinetics compares favorably with objective response to systemic therapy as a valid surrogate endpoint for survival. No significant financial relationships to disclose.

Abstract
284 Background: Recently, bladder-sparing protocols incorporating TUR + chemoradiotherapy (CRT) have been developed. Patients who achieve CR after CRT are subjects for bladder preservation treatment and those who with non-CR undergo radical cystectomy (RC). However, early studies suggest that RC following pelvic irradiation associates with a higher mortality. To validate the impact of induction CRT on perioperative morbidity of RC, we compared complications of RC in patients treated with or without induction CRT at a single university hospital. Methods: Records of consecutive 193 patients who underwent RC for bladder cancer between April 1989 and May 2010 were reviewed. Induction CRT consists of radiation at 40 Gy to the small pelvis and 2 cycles of concurrent cisplatin at 20 mg/d for 5 days. Any complications occurred within 30 days after RC were graded according to the Clavien-Dindo classification system. Complications of grade I or II were classified as minor and complications of grade III or greater were classified as major. Results: Eighty-seven patients underwent induction CRT (CRT group) while 106 did not (control group). Patients of CRT group had significantly more advanced disease. No patient died within 90 days. Twenty one (11%) patients experienced at least one major complications; there was no significant difference in the incidence of major complications between CRT and control group (14% vs. 8%, p = 0.26). The details were as follows; infectious (3.5% vs. 3.8%, p = 1.0), gastrointestinal (4.6% vs. 0.9%, p = 0.18), surgical (6.9% vs. 3.8%, p = 0.35), cardiovascular (1.2% vs. 0.9%, p = 1.0). There was no significant difference between the incidence of minor complications (61% vs. 51%, p = 0.19). Conclusions: Induction CRT at 40 Gy is unlikely to compromise subsequent RC. No significant financial relationships to disclose.

Abstract
374 Background: The widespread use of modern imaging techniques has resulted in the increased detection of small, asymptomatic renal tumors. Some recent studies from Western countries have reported that the incidence of benign lesions is approximately 15% in patients undergoing definitive surgery for renal masses presumed to be clinical stage I renal cell carcinoma (RCC). The high level of noncancerous lesions is, to some extent, due to the fact that no imaging feature can accurately distinguish either oncocytoma or lipid-poor angiomyolipma (AML) from RCC. This study attempts to determine the incidence of benign pathologic findings for such renal masses in Asian patients. Methods: Between 1991 and 2009, 711 consecutive patients (218 women and 493 men) underwent partial (n=206) or radical (n=505) nephrectomy for renal masses presumed to be stage T1N0M0 (T1a/T1b= 503/208) sporadic RCC on preoperative imaging in two Japanese centers. The mean size of the lesions was 3.3 cm (range 0.3-7.0). The pathologic features were reviewed by an experienced pathologist. Results: Of the 711 masses, 53 (7.5%) revealed benign pathologic findings. Twenty-two (3.1%) were AMLs, 13 (1.8%) were oncocytomas, 8 (1.1%) were complicated cysts, and 10 were others. Twenty-eight (12.8%) of the 218 females and 25 (5.1%) of the 493 males had benign lesions (p=0.0005). Of the 357 patients aged 60 years or younger, 37 (10.4%) had benign lesions while only 16 (4.5%) of the 354 patients over 60 years did (p=0.024). Forty six (9.2%) of the 503 T1a and 7 (3.4%) of the 203 T1b masses were benign (p=0.0071). A multivariate logistic regression model showed that sex, age and tumor size were all independently predictive of benign histology, particularly of AML. Conclusions: The present incidence (7.5%) of benign lesions in presumed clinical stage T1N0M0 RCC masses at nephrectomy was lower than the incidence of approximately 15% previously reported from Western countries, probably because of the low incidence of oncocytomas in Japanese patients. Female gender, young age and small tumor size are all independently predictive of benign lesions, particularly of AML in Japanese patients. No significant financial relationships to disclose.

Abstract
AIM The aim of this study was to evaluate the feasibility of our minimum incision endoscopic surgeries (MIES), adrenalectomy, radical nephrectomy and radical prostatectomy, which are operated via a single minimum incision which narrowly permits extraction of the specimen, using an endoscope, without gas insufflation, without any trocar ports and without injury to the peritoneum. These operations have been developed in our department in the late 1990 s and have since been performed in more than 1000 patients and certified as advanced surgery by the Japanese government in 2006. METHODS Adrenalectomy, radical nephrectomy and radical prostatectomy were carried out via a single minimum incision under the conditions of gasless, portless (without trocar ports), intact peritoneum and at low cost with reusable devices. The anatomic plane was separated through the incision and a wide working space was made extraperitoneally. New devices were made especially for this operation in our department, which are now commercially available. The results of the most recent consecutive cases (2005-2007) are evaluated. The results of adrenalectomy and radical nephrectomy performed by 12 operators including inexperienced doctors were compared with the initial results performed by 2 operators, mostly by one operator. RESULTS In the recent 60 cases of adrenalectomy, the average length of incision, operative time, estimated blood loss were 5.7 cm (5.6 cm in the initial 30 cases), 156 min (147 min) and 174 ml (139 ml), respectively. A complication was observed in one case, injury to the renal artery. Blood transfusion was not performed. Average days to oral feeding, to long walking (more than 100 m) and to possible minimal hospital stay were 1.3 days (2 days), 1.1 days (1.1 days) and 1.9 days (4.6 days), respectively. In the recent 80 cases of radical nephrectomy, the average length of incision, operative time, estimated blood loss were 6.6 cm (6.6 cm in the initial 80 cases), 192 min (186 min) and 315 ml (324 ml), respectively. Complications were not observed in any of the cases (2) and blood transfusion was performed in 1 case (3). Average days to oral feeding, to long walking (more than 100 m) and to possible minimal hospital stay were 1.1 days (1.4 days), 1.2 days (1.4 days) and 1.9 days (4.8 days), respectively. In the recent 50 cases of radical prostatectomy, the average length of incision and operative time were 5.9 cm and 261 min, respectively. Two complications (small rectal injuries) were observed and one blood transfusion was performed. Average days to oral feeding, to long walking (more than 100 m) and possible minimal hospital stay were 1.0 days, 1.0 days and 2.4 days, respectively. Wound pain was minimal and analgesics were generally not required on the second postoperative day in the above 3 operations. Although prophylactic antibiotics were not used in the recent cases of adrenalectomy and radical nephrectomy, surgical site infection was not observed. CONCLUSION Minimum incision endoscopic surgery (MIES) in Japanese urology is a safe, reproducible, cost-effective and minimally invasive treatment option for adrenal tumor, renal cell carcinoma and prostate carcinoma.

Abstract
Transplantation of mesothelial cells is used to repair peritoneum that is damaged by surgery, peritonitis, and peritoneal dialysis. The largest obstacle for clinical application of mesothelial cell transplantation is the lack of a reliable source of mesothelial cells. So far, they are isolated from omentum, mesentery, parietal wall and ascites. Procedures used to obtain mesothelial cells from the omentum or mesentery are invasive, however, especially in pre-operative situations. Sufficient amounts of ascites for aspiration can not be obtained under physiological conditions. We have developed a novel method of isolating mesothelial cells from the tunica vaginalis. The tunica vaginalis originates from the peritoneum and descends into the scrotum along with the testis during fetal development. This region provides a source of mesothelial cells that is convenient to approach and free from abdominal complications. Transplantation of autologous mesothelial cells that were isolated from tunica vaginalis was effective in preventing post-operative adhesions. In this review, we summarize mesothelial cell transplantation trials and describe the method of isolating mesothelial cells form the tunica vaginalis. Mesothelial cell transplantation might be widely accepted for clinical use in the near future.
