Abstract
Bone modifying agents (BMAs) have become a standard treatment to prevent skeletal-related events (SREs) in bone metastases (BMs). The aim of our study is to determine the clinical value of serum bone resorption markers for predicting clinical outcomes after using BMAs in patients with BM. Patients were enrolled between May 2013 and October 2017 at the Nagoya University Hospital, Japan. We prospectively observed changes in pyridinoline cross-linked carboxyterminal telopeptide of type I collagen (ICTP) and tartrate-resistant acid phosphatase 5b (TRACP-5b) during treatment with BMAs. The relationship between serum markers before and after treatment and clinical outcomes such as progression of bone disease (BD), SREs and overall survival (OS) were evaluated. Pearson chi-square test and Kaplan-Meier product limit methods were used for analysis. Sixty-seven patients were analyzed. The primary tumor sites were 21 lung, 16 breast and 30 others. Forty and 27 patients were treated with Denosumab and Zoledronic acid, respectively. Progression of BDs, SREs and death were observed in 10, 16 and 31 cases, respectively. The median follow-up period after using BMAs was 12.3 (range 0.3-66.3) months. ICTP at 3-4 weeks was significantly correlated with increasing BD progression, SREs and death after treatment in both the whole and lung cancer cohorts. Base line ICTP and TRACP-5b were also associated with increasing BD progression in the whole cohort. Our study showed that early posttreatment ICTP is useful for predicting BD progression, SREs and OS after use of BMAs in patients with BM and even in patients with lung cancer BM.

Abstract
INTRODUCTION This study aimed to determine the clinical significance of MRI characteristics as a possible predictor of responsiveness to meloxicam treatment in patients with desmoid-type fibromatosis (DF). Additionally, it analysed the correlation between CTNNB1 mutation status and signal intensity of MRI. METHODS Forty-six patients consecutively treated with meloxicam composed this study. The low-intensity area (LIA) on T2-weighted MRI was determined. We divided patients into two groups based on the efficacy of meloxicam: a clinical benefit group (CB group, including CR: complete response; PR: partial response; and SD: stable disease) and non-clinical benefit group (NB group, including PD: progressive disease). Correlations of the efficacy with LIA and CTNNB1 mutation status with LIA were investigated. RESULTS In total, 11, 17 and 18 patients showed PR, SD and PD, respectively. The mean LIA ratio before treatment was significantly higher (P < 0.001) in the CB group than in the NB group. For predicting the efficacy, sensitivity was 68%, and specificity was 89% when setting the cut-off value as 20% for LIA. Mean changes in the LIA ratio before and after treatment were significantly higher (P = 0.01) in the CB group than in the NB group. Mean LIA ratio before treatment was significantly lower (P < 0.001) in the S45F mutation group than in the other mutation group. In multivariate analysis, the LIA ratio before treatment was a significant predictor of responsiveness (P = 0.02). CONCLUSIONS MRI characteristics were a useful predictor of the efficacy of meloxicam in DF patients. It may be possible to predict the clinical outcome more accurately when combined with other factors, such as CTNNB1 mutantion status.

Abstract
11050 Background: Efficacy of low-dose chemotherapy with methotrexate (MTX) and vinblastine (VBL) for desmoid-type fibromatosis (DF) has been reported and approved by many physicians. However, significant factors including biomarker could not be identified to better predict the efficacy of this chemotherapy. Since 2003, meloxicam, which is a selective COX-2 inhibitor, has been applied consecutively as a first line treatment. We applied the low-dose chemotherapy with MTX+VBL for refractory patients. The aim of this study was to reveal the clinical outcome of low-dose chemotherapy with MTX+VBL, and determine the useful factors to predict the efficacy including CTNNB1 mutation status. Methods: Since 2003, 167 cases were histologically diagnosed as DF. Among them, 36 cases were treated with MTX (30mg/M2) +VBL (6mg/M2) chemotherapy. Treatment interval was basically 2 weeks according to our previous study. Effectiveness was evaluated with MRI and/or CT every 3 months according to Response Evaluation Criteria in Solid Tumors (RECIST). Frozen or FFPE (Formalin-Fixed Paraffin-Embedded) specimens obtained at biopsy or previous surgery were subjected to the analyses for CTNNB1 mutation status by Sanger method. Clinical outcome and factors correlating with the efficacy were analyzed. Results: Among 36 cases with this chemotherapy, male was 13, mean age at the treatment was 36±18 years. Mean maximum diameter of tumor was 15±18 cm. Twenty-nine cases (81%) harbored CTNNB1 or APC mutation. Mean treatment duration and cycles of MTX+VBL were 20 months and 29 cycles, respectively. According to RECIST, PD in 2, PR 1n 15, and SD in 19. According to CTCAE, Grade 3 or more adverse events were observed in only one case. CTNNB1 mutation status, gender, age, size, and location did not affect the outcome of RECIST. Longer treatment duration and cycles of chemotherapy were significantly associated with the outcome (P = 0.002 and 0.004, respectively). In 15 cases of PR, recurrent tumors significantly took longer time to get efficacy (P = 0.027), and tumors arising in trunk and extremities tended to take longer time (P = 0.1). Conclusions: Low-dose MTX+VBL chemotherapy is effective and feasible treatment for refractory DF regardless of CTNNB1 mutation status. Occasionally it takes time to obtain objective response.

Abstract
TPS11074 Background: Combination therapy to enhance the efficacy of T cell receptor (TCR)-engineered T cells (TCR-T) has received increasing attention. We found that a combination therapy of TCR-T and a long peptide vaccine with CpG adjuvant without lymphodepletion regimen caused regression of immune checkpoint inhibitor-resistant sarcoma in a preclinical mouse model. Based on this finding, we initiated a clinical trial of TBI-1301 combined with CHP:NE1 without lymphodepletion for the patients with NY-ESO-1-expressing advanced soft tissue sarcoma. TBI-1301 is an NY-ESO-1157–165/HLA-A*02:01- or -A*02:06-specific TCR-T engineered to reduce endogenous TCR mRNA expression. CHP:NE1 is a novel T cell stimulator consisting of NY-ESO-1 long peptide antigen, cholesteryl pullulan (CHP) nanogel, and CpG oligoDNA. CHP nanogel is used for efficient delivery of long peptide antigen into the lymph nodes. CpG oligoDNA is a TLR9 agonist and used as an adjuvant. CHP:NE1 is expected to reinforce TBI-1301 T cells in the lymph nodes. Methods: This is an investigator-initiated multi-institutional first-in-human phase I/II clinical trial. TBI-1301 is infused at 5×109 cells one day after subcutaneous injection of CHP:NE1. CHP:NE1 is injected again 7 days after TBI-1301 infusion. This cycle is repeated once more. Lymphodepletion using cyclophosphamide and/or fludarabine is not performed. Key inclusion criteria include: refractory soft tissue sarcoma with NY-ESO-1 antigen expression, HLA-A*02:01- or HLA-A*02:06- positive, ECOG Performance Status 0 or 1, and adequate organ function. The primary objective is to assess the safety and efficacy in the phase 1 and 2 parts, respectively. The secondary objective is to assess the efficacy and immune response (blood concentration, immunophenotype and activity of TBI-1301) in the phase 1 part and the safety and immune response in the phase 2 part. Enrollment in this study is currently ongoing. Clinical trial information: JMA-IIA00346.

Abstract
Leber congenital amaurosis (LCA) is a severe, genetically heterogeneous dystrophy of the retina and mutations in the nicotinamide mononucleotide adenylyltransferase 1 (NMNAT1) gene is one of causal factors of LCA. NMNAT1 is a nuclear enzyme essential for nicotinamide adenine dinucleotide (NAD) biosynthesis pathways, but the mechanisms underlying the LCA pathology and whether NMNAT1 has a role in normal retinal development remain unclear. Thus, we examined the roles of Nmnat1 in retinal development via short hairpin (sh)-RNA-mediated downregulation. Retinal explants expressing sh-Nmnat1 showed large numbers of apoptotic retinal progenitor cells in the inner half of the neuroblastic layer. Decreased intracellular NAD content was observed and the addition of NAD to the culture medium attenuated sh-Nmnat1-induced apoptosis. Of the nuclear Sirtuin (Sirt) family, the expression of sh-Sirt1 and sh-Sirt6 resulted in a phenotype similar to that of sh-Nmnat1. Sirt proteins are histone deacetylases and the expression of sh-Nmnat1 increased the levels of acetylated histones H3 and H4 in the retina. Expression of sh-Nmnat1 resulted in significantly increased expression of Noxa and Fas, two pro-apoptotic genes. Acetylation of the genomic 5′-untranslated regions of Noxa and Fas loci was upregulated by sh-Nmnat1 expression. The co-expression of sh-Fas with sh-Nmnat1 reduced the number of apoptotic cells induced by sh-Nmnat1 expression alone. Taken together, our data suggested that the increased expression of Noxa and Fas explains, at least in part, the phenotype associated with sh-Nmnat1 in the retina. Taken together, these findings demonstrate the importance of the NAD biosynthesis pathway in normal development of the retina.

Abstract
Hyaluronan (HA) has been shown to play crucial roles in the tumorigenicity of malignant tumors. Chondrosarcoma, particularly when low-grade, is characterized by the formation of an extracellular matrix (ECM) containing abundant HA, and its drug/radiation resistance has become a clinically relevant problem. This study aimed to evaluate the effects of an HA synthesis inhibitor, 4-methylumbelliferone (MU), on ECM formation as well as antitumor effects in chondrosarcoma. We investigated the effects of MU on rat chondrosarcoma (RCS) cells with a grade I histological malignancy in vitro and in vivo grafted model. HA binding protein (HABP) stainability on and around the RCS cells was effectively reduced with treatment of MU. ECM formation was markedly suppressed by MU at a dose of 1.0 mM. Cell proliferation was significantly reduced by MU at 24 h. Cell motility and invasion were suppressed in a dose-dependent manner by MU. No significant changes in mRNA expression of Has1-3 were observed. Furthermore, MU inhibited the growth of grafted tumors in vivo. Histologically, chondrosarcoma cells of control tumors showed a cell-clustering structure. HABP stainability was markedly decreased in the MU-treated group. These results suggest that MU exhibits antitumor effects on low-grade chondrosarcoma, via inhibition of HA accumulation and ECM formation. MU, which is an approved drug in bile therapy, could be a new off-label medication for chondrosarcomas. © 2017 Orthopaedic Research Society. Published by Wiley Periodicals, Inc.

Abstract
Background Thyroid metastasis of soft tissue sarcoma is very rare, and the diagnosis is especially difficult when only a single lesion is present. Case presentation A 50-year-old man was diagnosed with myxoid liposarcoma of the right thigh and treated with wide resection. Two and a half years after the surgery, a growing low-density area was incidentally observed in the right lobe of his thyroid gland on follow-up chest computed tomography. Fine needle aspiration biopsy was performed twice, and the thyroid mass was suspected of being a sarcoma metastasis. He was treated by hemithyroidectomy, and the lesion was pathologically confirmed as a metastasis of myxoid liposarcoma. Conclusion We experienced single thyroid gland metastasis in patients with myxoid liposarcoma in whom a growing mass is observed in the thyroid gland after radical surgery of the primary site.

Abstract
Accumulation of lipofuscin in the retinal pigmented epithelium (RPE) is observed in retinal degenerative diseases including Stargardt disease and age-related macular degeneration. Bis-retinoid N-retinyl-N-retinylidene ethanolamine (A2E) is a major component of lipofuscin. A2E has been implicated in RPE atrophy and retinal inflammation; however, mice with A2E accumulation display only a mild retinal phenotype. In the current study, human iPSC-RPE (hiPSC-RPE) cells were generated from healthy individuals to examine effects of A2E in human RPE cells. hiPSC-RPE cells displayed RPE-specific features, which include expression of RPE-specific genes, tight junction formation and ability to carry out phagocytosis. hiPSC-RPE cells demonstrated cell death and increased VEGF-A production in a time-dependent manner when they were cocultured with 10 μM of A2E. PCR array analyses revealed upregulation of 26 and 12 pro-inflammatory cytokines upon A2E and H2O2 exposure respectively, indicating that A2E and H2O2 can cause inflammation in human retinas. Notably, identified gene profiles were different between A2E- and H2O2-treated hiPSC-RPE cells. A2E caused inflammatory changes observed in retinal degenerative diseases more closely as compared to H2O2. Collectively, these data obtained with hiPSC-RPE cells provide evidence that A2E plays an important role in pathogenesis of retinal degenerative diseases in humans.

Abstract
PURPOSE Mice lacking ATP-binding cassette transporter 4 (ABCA4) and retinol dehydrogenase 8 (RDH8) mimic features of human Stargardt disease and age-related macular degeneration. RNA-sequencing of whole eyes was done to study early gene expression changes in Abca4-/-Rdh8-/- mice. METHODS Abca4-/-Rdh8-/- mice at 4 weeks of age were exposed to intense light. Total RNA was extracted from whole eyes and used to generate RNA libraries that were paired-end sequenced on the Illumina HiSeq 2500 device. Differentially expressed genes were annotated using Gene set enrichment analysis (GSEA). Selected genes in enriched pathways exhibiting differential expression were validated using quantitative qRT-PCR and ELISA. RESULTS Transcriptome analysis of the whole eye identified 200 genes that were differentially expressed 24 hours after light exposure compared to no light in Abca4-/-Rdh8-/- mice. Expression of several visual cycle and photoreceptor genes were decreased, indicative of photoreceptor/RPE cell death. Gene categories of early stress response genes, inflammatory cytokines, immune factors, and JAK STAT components were upregulated. Lipocalin 2 (Lcn2) was the most upregulated early stress response gene identified. Protein LCN2 was produced by RPE cells and the neural retina after intense light exposure as well as in cultured RPE cells from mice and humans incubated with lipopolysaccharide or photoreceptor outer segments. CONCLUSIONS Identification of important mediators involved in the crosstalk between the acute stress response and immune activation in RPE cells and the neural retina, such as LCN2, provide novel molecular targets for reducing cellular stress during retinal degeneration.

Abstract
Retinal tissues generated from human pluripotent stem cells can be an excellent tool for investigating pathogenesis of retinal diseases and developing new pharmacologic therapies. Moreover, patient derived retinal tissues could allow for retinal transplantation therapy for degenerative retinal diseases. However, obtaining retinal tissues with matured photoreceptor outer segments, which are essential for photoreceptor functions, is currently challenging. Here we investigated the effects of docosahexaenoic acid (DHA) for maturation of photoreceptor outer segments at the late stage and visual chromophore analog, 9-cis-retinal for the early stage of differentiation to three-dimensional (3D)-retinal tissues from human embryonic stem cells (hESCs), respectively. In the presence of DHA, differentiated 3D-retinal tissues demonstrated improved maturation of photoreceptor outer segments and increased number of photoreceptor cells compared with tissues without DHA. Increased mRNA expression of mature photoreceptor markers was additionally documented in retinal tissues cultured with DHA. Conversely supplementation with 9-cis-retinal failed to improve differentiation of retinal tissues perhaps due to chronic aldehyde toxicity. The current study demonstrated that the addition of DHA to culture medium can help promote differentiation of photoreceptor outer segments in vitro and utilization of this methodology may lead to future therapies for patients with blinding diseases.

Abstract
Stargardt disease is a progressive hereditary retinal disease which is currently incurable. Although ABCA4 has been identified as a major causative gene, patients with genetic mutations in other genes (PRPH2, ELOVL4, and PROM1) display similar clinical phenotypes as Stargardt disease. Recent advances in genetic and molecular studies have greatly enhanced our understanding of the disease and have led to identification of targetable pathophysiological progresses and new molecular clinical applications. Here we summarize the current understanding of the pathophysiology and potential therapies for Stargardt disease and other related retinal degenerative diseases.

Abstract
Accumulation of bis-retinoids in the retinal pigmented epithelium (RPE) is a hallmark of aging and retinal disorders such as Stargardt disease and age-related macular degeneration. These aberrant fluorescent condensation products, including di-retinoid-pyridinium-ethanolamine (A2E), are thought to be transferred to RPE cells primarily through phagocytosis of the photoreceptor outer segments. However, we observed by two-photon microscopy that mouse retinas incapable of phagocytosis due to a deficiency of the c-Mer proto-oncogene tyrosine kinase (Mertk) nonetheless contained fluorescent retinoid condensation material in their RPE. Primary RPE cells from Mertk-/- mice also accumulated fluorescent products in vitro Finally, quantification of A2E demonstrated the acquisition of retinal condensation products in Mertk-/- mouse RPE prior to retinal degeneration. In these mice, we identified activated microglial cells that likely were recruited to transport A2E-like condensation products to the RPE and dispose of the dying photoreceptor cells. These observations demonstrate a novel transport mechanism between photoreceptor cells and RPE that does not involve canonical Mertk-dependent phagocytosis.

Abstract
Giant cell tumor of bone (GCTB) is a primary benign bone tumor with a locally aggressive character. Definitive descriptions of the site of origin for this type of tumor are not available. The aim of the present study was to evaluate the site of origin of GCTB of long bones with regards to epiphyseal lines by means of radiographic examination. For that purpose, plain X-ray scans of 71 GCTBs arising in long bones were retrospectively reviewed. The tumor locations were the distal femur in 31 cases, proximal femur in 11 cases, proximal tibia in 13 cases, distal radius in 6 cases, proximal humerus in 5 cases and proximal fibula in 5 cases. The vertical center (VC) of the tumor was determined with X-ray anteroposterior view, and the correlation between the VC and the epiphyseal line, and between the distance from the epiphyseal line to the VC and tumor area or volume were analyzed using a regression model equation based on scatter plot diagrams. The VC of the tumor was located in the metaphyseal region in 57 cases, in the epiphyseal line in 11 cases and in the epiphyseal region in 3 cases. In cases of GCTB located in the distal femur or proximal tibia, significant correlations between the distance from the VC to the epiphyseal line and tumor area or volume were identified. The site of origin of GCTB was estimated to be located in the metaphyseal region. GCTB often occurs in mature patients, which renders it challenging to estimate the true site of origin of this lesion, since the metaphyseal line has disappeared in mature patients. The results of the present study suggest that GCTB possibly originates in the metaphyseal region.

Abstract
Few studies have analyzed Cathepsin K (CatK) expression in human osteoarthritic tissues. We investigated CatK expression and activation in human articular cartilage using clinical specimens. Human osteoarthritic cartilage was obtained during surgery of total hip arthroplasty (n = 10), and control cartilage was from that of femoral head replacement for femoral neck fracture (n = 10). CatB, CatK, CatL, CatS, and Cystatin C (CysC) expressions were evaluated immunohistochemically and by real-time PCR. Intracellular CatK protein was quantified by ELISA. Intracellular CatK activity was also investigated. Osteoarthritis (OA) chondrocytes were strongly stained with CatK, particularly in the superficial layer and more damaged areas. CatB, CatL, CatS, and CysC were weakly stained. CatK mRNA expression was significantly higher in OA group compared to that in control group (p = 0.043), whereas those of CatB, CatL, CatS, and CysC did not differ significantly. Mean CatK concentration (4.83 pmol/g protein) in OA chondrocytes was higher than that (3.91 pmol/g protein) in control chondrocytes (p = 0.001). CatK was enzymatically more activated in OA chondrocytes as compared with control chondrocytes. This study, for the first time, revealed increased CatK expression and activation in human OA cartilage, suggesting possible crucial roles for it in the pathogenesis of osteoarthritic change in articular cartilage.

Abstract
Desmoid tumors are benign mesenchymal neoplasms with a locally aggressive nature. The mutational status of β‐catenin gene (CTNNB1) is presumed to affect the tumorous activity of the cells. In this study, we isolated three kinds of desmoid cell with different CTNNB1 status, and compared their characteristics. Cells were isolated from three patients with abdominal wall desmoid during surgery, all of which were resistant to meloxicam treatment. The mutational status of the CTNNB1 exon 3 was determined for both parental tumor tissues and isolated cultured cells. β‐catenin expression was determined with immunohistochemistry. Responsiveness to meloxicam was investigated with MTS assay together with COX‐2 immunostaining. mRNA expressions of downstream molecules of Wnt/β‐catenin pathway were determined with real‐time RT‐PCR. Three kinds of cell isolated from desmoid tumors harboring different CTNNB1 mutation status (wild type, T41A, and S45F), all exhibited a spindle shape. These isolated cells could be cultured until the 20th passage with unchanged proliferative activity. Nuclear accumulation of β‐catenin was observed in all cultured cells, particularly in those with S45F. Proliferating activity was significantly suppressed by meloxicam (25 μmol/L, P < 0.007) in all three cell cultures, of which parental desmoid was resistant to meloxicam clinically. The mRNA expressions of Axin2, c‐Myc, and Cyclin D1 differently increased in the three cultured cell types as compared with those in human skin fibroblast cells (HDF). Inhibitors of Wnt/β‐catenin pathway downregulated Axin2, c‐Myc, and Cyclin D1 significantly. Isolated and cultured desmoid tumor cells harboring any one of the CTNNB1 mutation status had unique characteristics, and could be useful to investigate desmoid tumors with different mutation status of CTNNB1.

Abstract
Autophagy is an evolutionarily conserved catabolic mechanism that relieves cellular stress by removing/recycling damaged organelles and debris through the action of lysosomes. Compromised autophagy has been implicated in many neurodegenerative diseases, including retinal degeneration. Here we examined retinal phenotypes resulting from RPE-specific deletion of the autophagy regulatory gene Atg7 by generating Atg7(flox/flox);VMD2-rtTA-cre+ mice to determine whether autophagy is essential for RPE functions including retinoid recycling. Atg7-deficient RPE displayed abnormal morphology with increased RPE thickness, cellular debris and vacuole formation indicating that autophagy is important in maintaining RPE homeostasis. In contrast, 11-cis-retinal content, ERGs and retinal histology were normal in mice with Atg7-deficient RPE in both fasted and fed states. Because A2E accumulation in the RPE is associated with pathogenesis of both Stargardt disease and age-related macular degeneration (AMD) in humans, deletion of Abca4 was introduced into Atg7(flox/flox);VMD2-rtTA-cre+ mice to investigate the role of autophagy during A2E accumulation. Comparable A2E concentrations were detected in the eyes of 6-month-old mice with and without Atg7 from both Abca4(-/-) and Abca4(+/+) backgrounds. To identify other autophagy-related molecules involved in A2E accumulation, we performed gene expression array analysis on A2E-treated human RPE cells and found up-regulation of four autophagy related genes; DRAM1, NPC1, CASP3, and EIF2AK3/PERK. These observations indicate that Atg7-mediated autophagy is dispensable for retinoid recycling and A2E deposition; however, autophagy plays a role in coping with stress caused by A2E accumulation.

Abstract
Norrie disease is an X-linked recessive disorder that is characterized by congenital blindness. Although epileptic seizures are observed in some patients with Norrie disease, little is known about this phenomenon. Here, we report the manifestation of epilepsy in siblings with Norrie disease to increase our knowledge of epilepsy in this condition. Three brothers with congenital blindness were diagnosed with Norrie disease after genetic analyses indicated the deletion of exon 2 of the NDP gene. The eldest brother had suffered from epileptic seizures since the age of 11years, and his seizures were resistant to antiepileptic drugs. Although the second brother had no epileptic seizures, the youngest sibling had experiences epileptic seizures since the age of 8years. His seizures were controlled using lamotrigine and levetiracetam. An electroencephalography (EEG) revealed epileptiform discharges in the occipital areas in all three brothers. A study of these patients will increase our knowledge of epilepsy in patients with Norrie disease.

Abstract
A number of studies have assessed or modeled the distribution of the radionuclides released by the accident at the Fukushima-Daiichi Nuclear Power Plant (FDNPP). Few studies however have investigated its consequences for the local biota. We tested whether exposure of barn swallow (Hirundo rustica) nestlings to low dose ionizing radiation increased genetic damage to their peripheral erythrocytes. We estimated external radiation exposure by using thermoluminescent dosimeters, and by measuring radioactivity of the nest material. We then assessed DNA damage by means of the neutral comet assay. In addition, we conducted standard point-count censuses of barn swallows across environmental radiation levels, and estimated their abundance and local age ratio. Radioactivity of nest samples was in the range 479-143,349 Bq kg(-1), while external exposure varied between 0.15 and 4.9 mGy. Exposure to radioactive contamination did not correlate with higher genetic damage in nestlings. However, at higher levels of radioactive contamination the number of barn swallows declined and the fraction of juveniles decreased, indicating lower survival and lower reproduction and/or fledging rate. Thus, genetic damage to nestlings does not explain the decline of barn swallows in contaminated areas, and a proximate mechanism for the demographic effects documented here remains to be clarified.

Abstract
PURPOSE We previously found that Kcnj10, an inwardly-rectifying potassium channel, is a gene expressed in c-kit-positive retinal progenitor cells on P1. The shRNA-mediated screening of the functions of the genes for retinal development in retinal explant culture suggested a role for Kcnj10 in the differentiation of 23Müller glia. In the present study, we extended the work and focused on analyzing the role of Kcnj10 in retinal development. METHODS shRNA-mediated downregulation of Kcnj10 in retinal explants and the in vivo mouse retina at the P1 stage was performed. Differentiation and proliferation of the retina were examined with immunohistochemistry. The effect of barium (Ba(2+)) treatment, which inhibits potassium currents by blocking potassium channels, on retinal development was examined. RESULTS When Kcnj10 was downregulated at E18, cellular proliferation and morphological differentiation were perturbed; in particular, a decreased number of Müller glial cells with abnormal morphological maturation was observed. The overexpression of Kcnj10 in retinal progenitors did not result in gross abnormality during retinal development, but rescued the abnormal differentiation induced with sh-Kcnj10. The presence of Ba(2+) in the retinal explant medium led to a phenotype similar to that seen with sh-Kcnj10. Ba(2+) exerts an effect mainly during late retinal development, and sh-Kcnj10 in the P1 retina affected Müller glia maturation, suggesting that Kcnj10 plays a pivotal role in the maturation of retinal cell subsets. A previous study of Kcnj10-knockout mice showed no obvious abnormality in retinal differentiation, especially of Müller glia. We examined the effects of the downregulation of Kcnj10 with in vivo electroporation of sh-Kcnj10 in the P1 retina. Retinal differentiation was perturbed, as seen following the in vitro downregulation of Kcnj10, suggesting that compensatory gene expression and/or signaling occurred in the Kcnj10-knockout mice in the retina, leading to normal eye development. CONCLUSION Kcnj10 plays a role in Müller glia maturation during retinal development probably through ionic channel activities.

Abstract
The present study investigated the safety and efficacy of neoadjuvant and adjuvant chemotherapy with doxorubicin and ifosfamide for bone sarcoma in adult and older patients. A total of 18 consecutive patients with bone sarcoma (American Joint Committee on Cancer stage II in 14 patients and stage IV in four) treated with neoadjuvant and adjuvant chemotherapy at Nagoya Musculoskeletal Oncology Group hospitals in Japan between 2004 and 2011 were reviewed. The treatment efficacy and side-effects were evaluated. The responses to neoadjuvant chemotherapy were stable disease in 11 patients and progressive disease in three. Among the 12 evaluable patients, there were five with ≥90% tumor necrosis. The estimated overall survival (OS) rate at five years for the patients without metastasis prior to treatment was 56%. Major grade 3 or 4 side-effects included leukopenia in 14 cases, anemia in seven, thrombocytopenia in three, nausea in two and febrile neutropenia in two. One patient discontinued chemotherapy due to a temporarily depressed level of consciousness with arrhythmia (grade 2). The estimated five-year OS rate in this study was acceptable in patients without metastasis prior to treatment. A better coordinated prospective study of this combination regimen for older patients with bone sarcoma will be required to clarify its efficacy and tolerability.

Abstract
Hyaluronan (HA) regulates malignant tumor growth, invasion, and metastasis. However, few studies have focused on the roles of HA in tumorigenicity in malignant peripheral nerve sheath tumors (MPNST). In this study, we sought to clarify the prognostic value of HA in patients with MPNST. Specimens obtained from 15 patients with neurofibroma and 30 with MPNST were subjected to HA staining and scored as three grades. Protein expressions of HA synthase 1-3 were examined in the 22 MPNST tissue samples available. Statistically higher HA positivity was observed in MPNST as compared with neurofibroma (P = 0.020). The univariate analysis revealed that increased HA expression, age, neurofibromatosis type 1 (NF1) status, large tumor size, and histological grade were significantly associated with reduced overall survival of patients with MPNST; while increased HA expression, NF1 status, tumor size, and histological grade were correlated with disease-free survival. However, HA synthase 1-3 expression related to neither overall survival nor disease-free survival of these patients. In multivariate analysis, large tumor size (P = 0.022) was an independent prognostic factor for overall survival, and HA expression (P = 0.028) and tumor size (P = 0.002) were independent prognostic factors for disease-free survival. Statistically higher levels of HA in the human MPNST cells were observed compared with neurofibroma cells in vitro. Our results demonstrate that HA expression can be a useful marker in differentiating MPNST from neurofibroma, and in identifying patients with a poor prognosis. Hyaluronan-targeting therapy for patients with MPNST may have potential as a therapeutic tool.

Abstract
Background Unicameral bone cyst (UBC) is the most common benign lytic bone lesion seen in children. The aim of this study is to investigate clinical factors affecting pathological fracture and healing of UBC. Methods We retrospectively reviewed 155 UBC patients who consulted Nagoya musculoskeletal oncology group hospitals in Japan. Sixty of the 155 patients had pathological fracture at presentation. Of 141 patients with follow-up periods exceeding 6 months, 77 were followed conservatively and 64 treated by surgery. Results The fracture risk was significantly higher in the humerus than other bones. In multivariate analysis, ballooning of bone, cyst in long bone, male sex, thin cortical thickness and multilocular cyst were significant adverse prognostic factors for pathological fractures at presentation. The healing rates were 30% and 83% with observation and surgery, respectively. Multivariate analysis revealed that fracture at presentation and history of biopsy were good prognostic factors for healing of UBC in patients under observation. Conclusion The present results suggest that mechanical disruption of UBC such as fracture and biopsy promotes healing, and thus watchful waiting is indicated in these patients, whereas patients with poor prognostic factors for fractures should be considered for surgery.

Abstract
A 37-year-old woman with neurofibromatosis type 1 was referred for a rapidly growing plexiform neurofibroma of the left lower leg, acute serious pain, and leg palsy because of concern for malignant transformation of the tumor. Contrast-enhanced computed tomography confirmed a rupture of anterior tibial artery aneurysm, resulting in both anterior and posterior compartment syndrome in her left leg. Arterial involvement in neurofibromatosis is a well known; however, rupture of peripheral arteries is exceptional. Moreover, coexistence with plexiform neurofibroma occasionally delays the diagnosis with suspicion of malignant transformation without awareness of a vascular rupture.

Abstract
BACKGROUND Several previous reports have described multiple cancers with regard to epithelial tumors, but few reports have focused on multiple primary malignancies including soft tissue sarcomas (STS). METHODS The purpose of this study was to analyze the clinical features of patients with high-grade STS with multiple malignancies and possible clinical problems, compared with those with STS as a single malignancy, focusing on elderly patients. This study enrolled 107 patients aged 65 years or over with high-grade STS. RESULTS Eighty-four patients (79 %) had sarcomas only (S group), and 23 (21 %) had multiple primary malignancies (M group). STS preceded carcinoma in 10 patients, and carcinoma preceded STS in 13. In 7 patients (30 %), the interval between the first and second malignancy was less than a year. Of 7 patients who received treatment for sarcoma and carcinoma at the same time, the presence of other malignancies had an impact on determination of the treatment modality in 5 patients. The overall survival rate at 5 years was higher in M group (79 %) than in S group (69 %), although this difference was not significant (P = 0.095). CONCLUSIONS This study demonstrates that the presence of multiple malignancies was not correlated with a poor prognosis, and was actually associated with a better prognosis in elderly patients with STS. Physicians should be aware of the possible occurrence of a second malignancy, and on occasion the treatment modalities and their logistical aspects need to be well organized and carefully selected for patients with ongoing multiple malignancies.

Abstract
Background Gastric metastasis from osteosarcoma is very rare and its clinical features are not well recognized. Case presentation A 73-year-old man was diagnosed with osteosarcoma and treated with four cycles of preoperative chemotherapy with ifosfamide and doxorubicin followed by wide resection. Two cycles of postoperative chemotherapy with ifosfamide and doxorubicin and ten cycles of chemotherapy with carboplatin and etoposide were administered. Eleven months after the surgery, he vomited fresh blood. Unusual progression of anemia was observed with the hematemesis. A biopsy was performed by gastrointestinal endoscopy, and the stomach tumor was diagnosed as metastasis of osteosarcoma. Conclusions Even though gastric metastasis from osteosarcoma is very rare, all three previous reports and our case showed the presence of ulcer on the surface of the gastric lesion. We should consider the possibility of gastric metastasis in patients with osteosarcoma in whom progression of anemia or gastric hemorrhage is observed.

Abstract
OBJECTIVE Several studies have shown that cathepsin K (CTK) is overexpressed in osteoarthritic (OA) cartilage and subchondral bone. However, it has not been well established whether CTK expression is harmful or beneficial. We undertook this study to investigate the direct involvement of CTK in OA development using Ctsk-knockout (Ctsk(-/-)) mice in a joint instability-induced model of OA. METHODS We analyzed the natural course of the phenotype of 25-week-old Ctsk(-/-) mice. OA development was evaluated with a modified Mankin histologic score up to 8 weeks after surgery was performed to destabilize the knee in Ctsk(-/-) and Ctsk(+/+) mice. Histologic analysis was used to evaluate expression of CTK, matrix metalloproteinase 13 (MMP-13), ADAMTS-5, and tartrate-resistant acid phosphatase (TRAP) proteins in chondrocytes, synovial cells, and osteoclasts. Bone architecture was analyzed by histomorphometry. RESULTS Bone mineral content and bone volume were higher in Ctsk(-/-) mice at 25 weeks, whereas OA did not develop spontaneously in either Ctsk(-/-) or Ctsk(+/+) mice. In a model of destabilization-induced OA, OA progression was significantly delayed in Ctsk(-/-) mice. CTK was overexpressed in chondrocytes and synovial cells of knee joints developing OA in Ctsk(+/+) mice. MMP-13 and ADAMTS-5 were less strongly expressed in chondrocytes of Ctsk(-/-) mice, and MMP-13 was less strongly expressed in synovial cells. TRAP-positive osteoclasts were overexpressed in Ctsk(-/-) mice. CONCLUSION These results indicate that CTK plays crucial direct roles in the early to intermediate stage of OA development. CTK-positive chondrocytes and synovial cells may be a possible target to prevent disease progression in OA.

Abstract
Hyaluronan (HA) oligosaccharides were reported to have suppressive effects on various malignant tumors via disruption of receptor HA interactions. However, no studies have focused on the effects of HA oligosaccharides on bone metastasis of breast cancer. In this study, we clarified the effective size of HA oligosaccharides required to inhibit cell growth in the highly invasive breast cancer cell line, MDA-MB-231 cells. Based on the results of cell growth assay, we subsequently analyzed the effects of HA tetrasaccharides, HA decasaccharides, and high molecular weight HA on the other breast cancer cell behaviors in vitro and breast cancer bone metastasis in vivo. HA decasaccharides significantly inhibited cell growth, motility, and invasion, whereas tetrasaccharides did not. HAS2 mRNA expression was altered after the treatment with both tetrasaccharides and decasaccharides. Phosphorylation of Akt was suppressed after 1 h treatment with HA decasaccharides, and the effect was partially reversed by anti-CD44 monoclonal antibody. In vivo, local application of HA decasaccharides inhibited the expansion of osteolytic lesions in tibia on soft X-rays using mouse bone metastasis model of breast cancer. Histological analysis revealed HA accumulation in bone metastatic lesions was perturbed by decasaccharides. These results suggest that HA oligosaccharides suppressed progression of bone metastasis in breast cancer via interruption of endogenous HA-CD44 interaction, and as such, can be a novel therapeutic candidate to limit bone metastasis of breast cancer.

Abstract
Treatment modalities for desmoid tumors have been changed because of the high recurrence rate, even after wide resection, and some cases experience spontaneous self-regression during clinical course. The treatment modality in our institutions before 2003 was surgical resection with wide surgical margin, however, meloxicam, which is a NSAID and a selective COX-2 inhibitor has been applied consecutively since 2003. We reviewed the previously reported outcomes of surgical and conservative treatment in our institutions. Among 30 patients receiving surgical treatment, 16 (53%) recurred. Younger age ( p < 0.05) was a significant poor factor. According to RECIST for meloxicam treatment, CR was in one, PR in 10, SD in eight, PD in one evaluated at 2011. Older age ( p < 0.01) was significantly associated with good outcome for meloxicam treatment. Results of the previous study indicated that surgical treatment alone could not control desmoid tumors, even with negative surgical margin. Considering the functional impairment resulting from surgery with negative surgical margin, a conservative and effective treatment modality with fewer complications is desired. Conservative treatment with meloxicam is a promising novel modality for patients with extra-abdominal desmoid tumors.

Abstract
Hyaluronan (HA) has been shown to play crucial roles in the tumorigenicity of malignant tumors. Previous studies demonstrated that inhibition of HA suppressed the tumorigenicity of various malignant tumors including breast cancer. 4-methylumbelliferone (MU) has been reported to inhibit HA synthesis in several cell types. However, few studies have focused on the effects of HA inhibition in breast cancer cells by MU, nor the effects on bone metastasis. We hypothesized that MU would suppress the progression of bone metastasis via inhibition of HA synthesis. Here, we investigated the effects of MU on HA expression in MDA-MB-231 breast cancer cell line in addition to their tumorigenicity in vitro and in vivo. HAS2 mRNA expression was downregulated after 6 and 24 hr treatment with MU. Quantitative analysis of HA revealed that MU significantly inhibited the intracellular and cell surface HA. MU significantly inhibited cell growth and induced apoptosis as determined by cell proliferation and TUNEL assays, respectively. Phosphorylation of Akt was suppressed after 12 and 24 hr treatment with MU. MU treatment also inhibited cell motility as well as cell invasiveness. MU also inhibited cell growth and motility in murine fibroblast cell line NIH3T3. In vivo, administration of MU inhibited the expansion of osteolytic lesions on soft X-rays in mouse breast cancer xenograft models. HA accumulation in bone metastatic lesions was perturbed peripherally. These data suggest that MU might be a therapeutic candidate for bone metastasis of breast cancer via suppression of HA synthesis and accumulation.

Abstract
BACKGROUND Soft tissue sarcomas are often inappropriately excised without adequate preoperative planning. Inappropriate (unplanned) excisions may adversely affect local recurrence, distant metastasis, patient survival, and /or postoperative function once properly evaluated. QUESTIONS/PURPOSES We asked whether the clinical and treatment characteristics, survival (overall, local recurrence-free, distant metastasis-free), and functional scores of patients with unplanned excisions differ from those with a planned excision. METHODS We retrospectively reviewed 128 patients with planned excisions and 63 patients with unplanned excisions at prereferral hospitals followed by additional reexcisions. We determined whether age, gender, tumor size, depth, histologic grade, operative duration, blood loss, survival, or functional scores differed between the two groups. The minimum followup was 6 months (mean, 55 months; range, 6-275 months). RESULTS The tumor was larger and its location deeper in the planned excision group. Overall, metastasis-free, and local recurrence-free survival were similar in the two groups: 86%, 71%, and 85% in the planned excision group and 96%, 86%, and 92% in the unplanned excision group, respectively. However, additional soft tissue reconstruction was more often necessary for patients with unplanned excisions. No difference in postoperative function was observed. CONCLUSIONS The data suggest an adequate additional wide excision may improve the local control and survival in patients with an unplanned excision as well as the patients with a planned excision. While patients with unplanned excisions had superficial and smaller tumors, survival and postoperative function were similar to those with planned excisions.

Abstract
UNLABELLED Granular cell tumors are uncommon but typically histologically benign neoplasms that occasionally behave as malignant tumors. Differentiation of benign granular cell tumors from malignant counterparts with radiographic and/or histologic analysis is crucial for physicians. We retrospectively studied five cases of intramuscular granular cell tumors arising in the lower extremities. All tumors had been histologically diagnosed as benign and were resected with a wide surgical margin. The minimum followup was 1 year (mean, 45 months; range, 12-119 months) after surgery. Four patients had no local recurrence or distant metastasis (at a minimum of 18 months followup), whereas one patient with lymph node metastasis had a recurrence and distant metastasis 3 months after surgery resulting in death. Intramuscular granular cell tumors can be diagnosed based on their characteristic MRI features, such as peripheral high intensity on T2-weighed images, and histologic evaluation. The histologic criteria described by Fanburg-Smith et al. can differentiate malignant granular cell tumors from benign tumors. A wide resection seems suitable for most granular cell tumors in the extremities. LEVEL OF EVIDENCE Level IV, diagnostic study. See the Guidelines for Authors for a complete description of evidence.
