Abstract
Aims The standard of surgical treatment for lower limb neoplasms had been characterized by highly interventional techniques, leading to severe kinetic impairment of the patients and incidences of phantom pain. Rotationplasty had arisen as a potent limb salvage treatment option for young cancer patients with lower limb bone tumours, but its impact on the gait through comparative studies still remains unclear several years after the introduction of the procedure. The aim of this study is to assess the effect of rotationplasty on gait parameters measured by gait analysis compared to healthy individuals. Methods The MEDLINE, Scopus, and Cochrane databases were systematically searched without time restriction until 10 January 2022 for eligible studies. Gait parameters measured by gait analysis were the outcomes of interest. Results Three studies were eligible for analyses. Compared to healthy individuals, rotationplasty significantly decreased gait velocity (-1.45 cm/sec; 95% confidence interval (CI) -1.98 to -0.93; p < 0.001), stride length (-1.20 cm; 95% CI -2.31 to -0.09; p < 0.001), cadence (-0.83 stride/min; 95% (CI -1.29 to -0.36; p < 0.001), and non-significantly increased cycle time (0.54 sec; 95% CI -0.42 to 1.51; p = 0.184). Conclusion Rotationplasty is a valid option for the management of lower limb bone tumours in young cancer patients. Larger studies, with high patient accrual, refined surgical techniques, and well planned rehabilitation strategies, are required to further improve the reported outcomes of this procedure.

Immediate Plastic Surgery Intervention after Soft Tissue Sarcoma Resection: Examining Wound Healing, Readmission, and Reoperation. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2023; 11:e4988. [PMID: 37305195 PMCID: PMC10256372 DOI: 10.1097/gox.0000000000004988] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2022] [Accepted: 03/16/2023] [Indexed: 06/13/2023]
Abstract
Many orthopedic and surgical oncologists use a multidisciplinary approach to soft tissue sarcoma (STS) resection. This study assesses the role of immediate plastic surgeon involvement during index soft tissue sarcoma resection. Methods Adult patients who underwent index STS resection between 2005 and 2018 were queried from an institutional database. Main outcomes analyzed were 90-day same-site reoperation, any-cause readmission, and wound healing complications. Univariate and multivariate logistic regression were used to identify risk factors. Additional evaluation was then performed for the following two cohorts: patients with and without plastic surgeon involvement. Results In total, 228 cases were analyzed. Multivariate regression demonstrated the following predictors for 90-day wound-healing complications: plastic surgery intervention [OR = 0.321 (0.141-0.728), P = 0.007], operative time [OR = 1.003 (1.000-1.006), P = 0.039], and hospital length of stay [OR = 1.195 (1.004-1.367), P = 0.010]. For 90-day readmission, operative time [OR = 1.004 (1.001-1.007), P = 0.023] and tumor stage [OR = 1.966 (1.140-3.389), P = 0.015] emerged as multivariate predictors. Patients whose resection included a plastic surgeon experienced similar primary outcomes despite these patients having expectedly longer operative times (220 ± 182 versus 108 ± 67 minutes, P < 0.001) and hospital length of stay (3.99 ± 3.69 versus 1.36 ± 1.97 days, P < 0.001). Conclusions Plastic surgeon involvement emerged as a significant protector against 90-day wound healing complications. Cases that included plastic surgeons achieved similar complication rates in all categories relative to cases without plastic surgery intervention, despite greater operative time, hospital length of stay, and medical complications.

Abstract
BACKGROUND/AIM We have previously developed a novel bone-targeting platinum compound, 3Pt, and showed that it has strong inhibitory activity against osteosarcoma cells and orthotopic cell-line xenograft mouse models. In the present report, we compared the efficacy of 3Pt to cisplatinum (CDDP) in a CDDP-resistant relapsed osteosarcoma patient-derived orthotopic xenograft (PDOX) mouse model. PATIENTS AND METHODS The tumor of a patient with osteosarcoma of the distal femur was treated with CDDP-based chemotherapy followed by surgery. The surgical specimen was used to establish a PDOX model. An osteosarcoma cell line was also established from the original patient tumor. Osteosarcoma cell viability was assessed with the WST-8 assay and the IC50 values were calculated. The PDOX models were randomized into three groups: untreated control, CDDP-treated group, and 3Pt-treated group. Tumor size and body weight were measured twice a week. RESULTS 3Pt had a strong concentration-dependent cytocidal effect in vitro. The IC50 value of 3Pt was significantly lower than that of CDDP. On day 14 of the treatment, 3Pt caused a significantly greater tumor growth inhibition compared to the untreated control and CDDP-treated mice. CONCLUSION 3Pt is a promising clinical candidate for the treatment of recalcitrant osteosarcoma.

Abstract
Bone diseases, such as bone cancer, bone infection and osteoporosis, constitute a major issue for modern societies as a consequence of their progressive ageing. Even though these pathologies can be currently treated in the clinic, some of those treatments present drawbacks that may lead to severe complications. For instance, chemotherapy lacks great tumor tissue selectivity, affecting healthy and diseased tissues. In addition, the inappropriate use of antimicrobials is leading to the appearance of drug-resistant bacteria and persistent biofilms, rendering current antibiotics useless. Furthermore, current antiosteoporotic treatments present many side effects as a consequence of their poor bioavailability and the need to use higher doses. In view of the existing evidence, the encapsulation and selective delivery to the diseased tissues of the different therapeutic compounds seem highly convenient. In this sense, silica-based mesoporous nanoparticles offer great loading capacity within their pores, the possibility of modifying the surface to target the particles to the malignant areas and great biocompatibility. This manuscript is intended to be a comprehensive review of the available literature on complex bone diseases treated with silica-based mesoporous nanoparticles-the further development of which and eventual translation into the clinic could bring significant benefits for our future society.

Abstract
Osteosarcoma is one of the most malignant bone tumors, and its major threats are aggressive invasion and early tumor metastasis, which result in a poor prognosis and high mortality. Accumulating evidence indicates that ginsenoside compound K (CK) has a significant antitumor effect, particularly on the inhibition of proliferation and invasion of numerous human tumors. In the present study, it was revealed that CK inhibited the viability and proliferation of osteosarcoma cells. Moreover, it was demonstrated that CK induced apoptosis and inhibited the migration and invasion of osteosarcoma cells via apoptotic staining, Annexin V/PI staining, and Transwell invasion assays. Furthermore, at the molecular level, the present results confirmed that apoptosis and invasion-related proteins were regulated by CK, which was possibly related to the blockade of the PI3K/mTOR/p70S6K1 signaling pathway. In summary, the present findings indicated that CK inhibited viability and proliferation, induced apoptosis, and inhibited the migration and invasion of osteosarcoma cells through the PI3K/mTOR/p70S6K1 signaling pathway.

Abstract
Matrine and adriamycin have been extensively considered to be effective in anticancer therapies. However, the role of matrine in the antitumor activity of adriamycin against human osteosarcoma (OS) remains elusive. The aim of this study was to investigate the effect of matrine in OS chemotherapy of adriamycin. In the study, we found that matrine promoted the inhibitory effect of adriamycin against OS cell proliferation and growth. Wound healing and transwell assays showed that the inhibitory effect of adriamycin against migration and invasion of OS cells was significantly enhanced by matrine. For the underlying mechanism investigation, we showed that adriamycin reduced the protein level of PCNA, MMP-9, phosphorylated STAT3, and survivin, which was further intensified by the application of matrine. These results show that matrine could promote the therapeutic efficacy of adriamycin against human OS.

Abstract
Management of degenerative spine pathologies frequently leads to the need for bone growth. Rehmanniae Radix (RR), a Chinese herbal formulation was found to exhibit numerous therapeutic properties including its potent effect against cancer cell lines. However, the underlying mechanism through which the Zinc oxide nanoparticles (ZnONPs) synthesized from Rehmanniae Radix exerts its anti-cancer activity against osteosarcoma cell line MG-63 needs to be explored. Therefore, the study was performed to evaluate the anticancer, cytotoxicity and apoptotic effectiveness of ZnONPs from RR against MG-63 cells. Characterization studies such UV-vis spectroscopy, FTIR, TEM and XRD analysis were performed. Cytotoxicity assay, mitochondrial membrane potential (MMP), morphological examination of cells and formation of reactive oxygen species (ROS), and apoptosis inducing ability of RR were evaluated by various procedures. Western blot analysis of apoptotic markers such as Bax, caspase-3 and caspase-9 were also performed. RR was found to inhibit growth of MG-63 cells at increasing dose. AO/EB staining confirmed the apoptotic efficacy of ZnONPs induced by RR in MG-63 cells. ZnONPs was also found to initiate increased generation of ROS and decreased MMP. Decreased MMP has resulted in increased levels of apoptotic proteins Bax, caspase-3 and caspase-9 and induction of apoptosis was substantiated by western blot analysis. The outcomes of the work propose that ZnONPs from RR exhibits strong anticancer action and inducing apoptosis on MG-63 cells via stimulating increased generation of ROS. Thus, ZnONPs from RR might be used as a hopeful drug target against several types of cancer cell lines.

Abstract
BACKGROUND Attempts to salvage upper and lower extremities have performed more frequently in recent decades, although there are clear cases that cannot be salvaged. The purpose of this retrospective study was to present our experience in using free calcaneus osteocutaneous fillet flap for preserving below-knee amputation stump after traumatic amputations or functional preserving after nonsalvageable lower extremities. METHODS Between January 2012 and May 2017, 11 free calcaneus osteocutaneous fillet flap were used to preserving or lengthening below-knee amputation stump secondary to amputation on 8 males and 3 females. Patients' information and postoperative data were collected, including age of patient, sex, amputation site, flap survival, sensation recovery, and number of complications. RESULT All amputations were trauma related and secondary to motor vehicle accidents (n = 8) and industrial accidents (n = 3). The age of the patients ranged from 16 to 59 years, with a mean of 34.4 years. Free calcaneus osteocutaneous fillet flap were designed and harvested from all patients. All flaps survived and 2 complications developed in 2 patients. Nine of 11 patients obtained protective sensory recovery during the period of follow-up. CONCLUSIONS The free calcaneus osteocutaneous fillet flap harvested from the amputated limb provides reliable and robust tissue for reconstruction of large defects of the residual limb without additional donor-site morbidity.

Abstract
Bone primary tumors, such as osteosarcoma, are highly aggressive pediatric tumors that in 30% of the cases develop lung metastasis and are characterized by poor prognosis. Bone is also the third most common metastatic site in patients with advanced cancer and once tumor cells become homed to the skeleton, the disease is usually considered incurable, and treatment is only palliative. Bone sarcoma and bone metastasis share the same tissue microenvironment and niches. 3D cultures represent a new promising approach for the study of interactions between tumor cells and other cellular or acellular components of the tumor microenvironment (i.e., fibroblasts, mesenchymal stem cells, bone ECM). Indeed, 3D models can mimic physiological interactions that are crucial to modulate response to soluble paracrine factors, tumor drug resistance and aggressiveness and, in all, these innovative models might be able of bypassing the use of animal-based preclinical cancer models. To date, both static and dynamic 3D cell culture models have been shown to be particularly suited for screening of anticancer agents and might provide accurate information, translating in vitro cell cultures into precision medicine. In this mini-review, we will summarize the current state-of-the-art in the field of bone tumors, both primary and metastatic, illustrating the different methods and techniques employed to realize 3D cell culture systems and new results achieved in a field that paves the way toward personalized medicine.

Abstract
BACKGROUND However, the application of limb salvage with joint preservation is controversial. The purpose of this study is to propose a selection strategy of joint-sparing operative procedures for humeral malignancies based on tumor origin, site and bone strength. METHODS The medical data of 28 patients with humeral malignancies treated at our institute from January 2010 to December 2016 were analyzed retrospectively. The patients had a median age of 51 years (range, 8-82 years). Bone strength scoring system was utilized to evaluated bone strength of the tumor. Four joint-sparing surgical methods were performed on selected patients. Evaluation of limb function was based on the Musculoskeletal Tumor Society scoring system. Two-sample t-test was used to compare patient group data such as bone strength score and postoperative Musculoskeletal Tumor Society score. RESULTS The mean follow-up period for the 7 patients with primary malignancies was 45 months (range, 15-66 months). One patient died due to recurrence and lung metastasis, while the remaining 6 patients (6/7, 85.7%) survived without recurrence. For the 21 patients with metastases, 5 survived with tumors, with an average survival time of 25.8 months (range, 9-48 months). The rest died from progression of the primary tumors. The mean bone strength score for the biological reconstruction group and non-biological reconstruction group was respectively 9.7 ± 1.3 and 12.9 ± 1.2. A significant difference between the 2 groups (p < 0.05) was found. Mean postoperative Musculoskeletal Tumor Society score was respectively 27.2 ± 1.8 and 26.1 ± 1.7 for the 2 groups. There was no significant difference between the 2 groups (p > 0.05). Non-oncological complications included fracture (1), aseptic loosening (1) and radial nerve injury (1). CONCLUSIONS Alcohol devitalized autograft replantation is applicable for diaphyseal humeral primary malignancies, with a good response to chemotherapy and a low bone strength score (≤10). In situ microwave ablation is suitable for diaphyseal and (or) metaphyseal low-grade malignant bone tumors or metastases with a low bone strength score (≤10). Intercalary prosthetic reconstruction is preferred for diaphyseal metastases with a high bone strength score (> 10).

Salidroside suppresses the growth and invasion of human osteosarcoma cell lines MG63 and U2OS in vitro by inhibiting the JAK2/STAT3 signaling pathway. Int J Oncol 2019; 54:1969-1980. [PMID: 31081055 PMCID: PMC6521935 DOI: 10.3892/ijo.2019.4781] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2018] [Accepted: 03/14/2019] [Indexed: 12/21/2022] Open
Abstract
Previous research has reported that salidroside exerts antitumor properties on numerous types of tumor cells; however, its effect on osteosarcoma cells remains unknown. The present study aimed to investigate the effects of salidroside on the viability, apoptosis and invasion of osteosarcoma cells in vitro, and determine the underlying mechanism of action. The results of an MTT revealed that salidroside suppressed the viability of osteosarcoma cells (MG63 and U2OS cells) in a time- and concentration-dependent manner. The results of cell morphological analysis (profile observations and Hoechst 33258 staining) and the detection of apoptosis by flow cytometry further indicated that the decrease in osteosarcoma cell viability induced by salidroside was associated with cell apoptosis. Western blot analysis not only confirmed these results but also suggested that salidroside induced the apoptosis of osteosarcoma cells by activating the caspase-9-dependent apoptotic pathway. In addition, we reported that salidroside induced G0/G1 phase arrest and suppressed the invasion of osteosarcoma cells, as measured by flow cytometric cell cycle analysis and a Transwell invasion assay, respectively. Western blot analysis confirmed the aforementioned results. Furthermore, our findings demonstrated that salidroside induced the apoptosis, G0/G1 phase arrest and suppressed the invasion of osteosarcoma cells by inhibiting the janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway, as determined by western blot analysis. In summary, the findings of the present study suggested that salidroside may inhibit the progression of osteosarcoma by suppressing the growth and invasion of osteosarcoma cells. Furthermore, the investigations into the underlying mechanism demonstrated that salidroside exerted notable antitumor activity in osteosarcoma cells by inhibiting the JAK2/STAT3 signaling pathway.

Abstract
The neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) are not fully evaluated for the diagnosis of musculoskeletal tumors, especially spine tumors. The objective of our study was to assess the feasibility of NLR and PLR as indicators for pretreatment diagnosis of spine tumors.Patients who underwent surgical treatment in our hospital for spine tumors were retrospectively analyzed. Blood test results (neutrophil, lymphocyte, and platelet counts) and final pathological results from surgery or biopsy specimen were collected. Spine tumors were divided into 4 groups. Diagnostic values of NLR and PLR were analyzed using the area under the receiver operating characteristic (ROC) curve (AUC).There were 503 patients included. The average age of all patients was 46.3 years. Age, NLR, and PLR were significantly different between benign and malignant tumors groups (P < .05), and ROC analysis showed that the AUC was 0.704 and 0.637 for NLR and PLR. Age, location, NLR, and PLR were significantly different between primary and nonprimary tumor groups (P < .05), and ROC analysis showed that the AUC was 0.713 and 0.647 for NLR and PLR. Age, location, NLR, and PLR were significantly different between primary benign and primary malignant tumor groups (P < .05), and ROC analysis showed that the AUC was 0.624 and 0.577 for NLR and PLR.Pretreatment NLR and PLR had clinical significance in the identification and pretreatment diagnosis of spine tumors. Additionally, NLR and PLR were significantly different between benign and malignant tumors, primary and nonprimary tumors, and primary benign and primary malignant tumors.

[PMID: 30675226 PMCID: PMC6341607 DOI: 10.3892/ol.2018.9749] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2017] [Accepted: 09/13/2018] [Indexed: 12/15/2022] Open
Abstract
Chemoresistance implicates the therapeutic value of cisplatin and remains a primary obstacle to its clinical use. MicroRNAs (miRs) negatively modulate the expression of their target genes and are associated with the occurrence and progression of various types of tumor. The abnormal expression of miR-504 has been reported in certain types of human tumor and has been associated with tumor prognosis. However, the association between miR-504 and cisplatin in human osteosarcoma remains unclear. The present study therefore aimed to assess the in vitro effects and possible mechanism of miR-504 in cell proliferation, apoptosis and cisplatin resistance in MG63 osteosarcoma cells. The results demonstrated that miR-504 was overexpressed in osteosarcoma tissues and cells. This overexpression also induced cell proliferation, as determined by MTT and EdU staining assays. Furthermore, miR-504 suppressed cisplatin-induced apoptosis, which was demonstrated via MTT, cell morphology analysis and flow cytometry. Cisplatin-induced G1 arrest was also suppressed, which was determined by flow cytometry. The potential target genes of miR-504 were predicted using bioinformatics. p53 was confirmed to be a direct target of miR-504 using a luciferase reporter assay and western blot analysis revealed that miR-504 negatively regulated p53 expression at a molecular level. These results indicate that miR-504 contributes to cisplatin resistance in MG63 osteosarcoma cells by suppressing p53. miR-504 may therefore be a potential biomarker for cisplatin resistance in patients with osteosarcoma.

Abstract
INTRODUCTION Patients with complex medical and surgical problems often travel great distances to prestigious university medical centers in search of solutions and in some cases for nothing more than a diagnosis of their condition. Translational medicine (TM) is an emerging method and process of facilitating medical advances efficiently from the scientist to the clinician. Most established clinicians and those in training know very little about this new discipline. The purpose of this article is to illustrate TM in varied scientific, medical and surgical fields. MATERIALS AND METHODS Anecdotal events in medicine and orthopaedics based upon a practicing orthopaedic surgeon's training and clinical experience are presented. RESULTS TM is rapidly assuming a greater presence in the medical community. The National Institute of Health (NIH) recognizes this discipline and has funded TM projects. Numerous institutions in Europe and the USA offer advanced degrees in TM. Finally there is a European Society for Translational Medicine (EUTMS), an International Society for Translational Medicine, and an Academy of Translational Medical Professionals (ATMP). DISCUSSION The examples of TM presented in this article support the argument for the formation of more TM networks on the local and regional levels. The need for increased participation of researchers and clinicians requires further study to identify the economic and social impact of TM. CONCLUSIONS The examples of TM presented in this article support the argument for the formation of more TM networks on the local and regional levels. Financial constraints for TM can be overcome by pooling government, academic, private, and industry resources in an organized fashion with oversight by a lead TM researcher.

A Longitudinal Study of Functional Outcomes in Patients with Limb Salvage Surgery for Soft Tissue Sarcoma. Sarcoma 2018; 2018:6846275. [PMID: 30123044 PMCID: PMC6079357 DOI: 10.1155/2018/6846275] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2017] [Revised: 01/08/2018] [Accepted: 02/26/2018] [Indexed: 01/13/2023] Open
Abstract
Background Many studies have reported on the surgical outcomes of soft tissue sarcoma. However, there was no longitudinal cohort study. Because time is the most valuable factor for functional recovery, adjusting time value was the key for finding the causal relationship between other risk factors and postoperative function. Therefore, existing cross-sectional studies can neither fully explain the causal relationship between the risk factors and the functional score nor predict functional recovery. The aim of this study was to determine important predictive factors that affect postoperative functional outcomes and longitudinal changes in functional outcomes in patients who had undergone limb-sparing surgery (LSS) for soft tissue sarcoma (STS). Methods Between January 2008 and December 2014, we retrospectively enrolled 150 patients who had undergone LSS for STS and had been assessed for postoperative functional outcomes with questionnaires. To evaluate functional outcomes, we used the Musculoskeletal Tumor Society (MSTS) score and Toronto Extremity Salvage Score (TESS). Multivariate generalized estimating equation (GEE) analysis was used to identify the predictive factors, including size, stage, and anatomic location of tumor, bone resection, flap reconstruction, age, and time after surgery. Each continuous variable such as age and time after surgery was explored for statistically significant cutoff points using the Wilcoxon rank sum test. Results Functional scores significantly improved until the second year after surgery and plateaued for the rest of the 5-year period. Age (p < 0.0001), bone resection (p=0.0004), and time after surgery (p < 0.0001) were identified as significant predictive factors. The functional score was significantly higher in patients younger than 47 years old. Conclusions Functional outcomes can improve until the second year after surgery. Patients who were older than 47 and underwent bone resection may have poor final functional outcomes.

Abstract
Accumulating evidence indicates that microRNA-203 (miR-203) is abnormally expressed in many human tumor tissues and significantly associated with the occurrence, development and clinical outcomes of human tumors. The aim of this study was to determine the target genes and functional significance of miR-203 in osteosarcoma cells. We found reduced expression of miR-203 in osteosarcoma tissues and cells (MG63 and U2-OS) compared with the adjacent normal tissues and normal osteoblastic cells (hFOB1.19), respectively. In vitro studies further demonstrated that exogenous miR-203 overexpression inhibited osteosarcoma cell proliferation and invasion, and promoted apoptosis. At the molecular level, our results confirmed that apoptosis, cell cycle and invasion-related proteins were regulated by miR-203. Our findings also revealed that Runt-related transcription factor 2 (RUNX2) was directly negatively regulated by miR-203. These results suggested that miR-203 may function as a tumor suppressor and may therefore have therapeutic potential in the treatment of human osteosarcoma.

Ameloblastin induces tumor suppressive phenotype and enhances chemosensitivity to doxorubicin via Src-Stat3 inactivation in osteosarcoma. Sci Rep 2017; 7:40187.

Abstract
Ameloblastin (AMBN), the most abundant non-amelogenin enamel matrix protein, plays a role in ameloblast differentiation. Previously, we found that AMBN promoted osteogenic differentiation via the interaction between CD63 and integrin β1, leading to the inactivation of Src; however, how AMBN affects the malignant behavior of osteosarcoma is still unclear. Osteosarcoma affects the bone and is associated with poor prognosis because of the high rate of pulmonary metastases and drug resistance. Here we demonstrated that stable overexpression of AMBN induced apoptosis and suppressed colony formation and cell migration via the inactivation of Src-Stat3 pathway in human osteosarcoma cells. Moreover, AMBN induced chemosensitivity to doxorubicin. Thus, AMBN induced a tumor suppressive phenotype and chemosensitivity to doxorubicin via the AMBN-Src-Stat3 axis in osteosarcoma. Indeed, immunohistochemical expression of AMBN was significantly correlated with better outcome of osteosarcoma patients. Our findings suggest that AMBN can be a new prognostic marker and therapeutic target for osteosarcoma combined with conventional doxorubicin treatment.

Abstract
Background Complete resection of pelvic bone tumors, especially recurrent and metastatic ones, is often impossible to achieve using conventional surgery. This study aimed to assess the benefits and adverse effects of computed tomography (CT)-guided radioiodine (125I) brachytherapy for inoperable recurrent and metastatic bone tumors of the pelvis. Methods This was a retrospective study of 22 patients with confirmed pelvic bone tumors (10 females and 12 males; 15–84 years; 21 with primary pelvic tumor and one with pelvic metastasis). CT-guided 125I brachytherapy was performed using 9–21 125I seeds (radioactivity of 0.5–0.7 mCi). Seed implantation was validated by postoperative CT scanning. Complications, pain, survival, and CT-estimated tumor size were carried out to evaluate the therapeutic benefits. Results Postoperative CT scans revealed satisfactory 125I seed implantation, and the radiation dose delivered to 90% of the target area (D90) was higher than the prescription dose (PD). No obvious complications were observed. Pain was reported by 19 of 22 patients, but 17 reported pain relief after implantation. Follow-up ranged 8–27 (median, 19) months. Tumor size was reduced in 11 patients within 1 month after surgery, nine patients showed no change, and tumor size increased in two patients. Finally, 1- and 2-year survival was 81.8 and 45.5%, respectively; 1- and 2-year local tumor control rates were 59.1 and 36.4%, respectively. Conclusions 125I seed implantation significantly reduced bone tumor size and relieved pain, with a low complication rate. These findings suggest that 125I brachytherapy treatment could be a useful palliative approach for pelvic bone tumor treatment.

Abstract
Recent studies have revealed that increased expression of the alpha subunit of nuclear transcription factor Y (NF‑YA) is associated with the malignant phenotype of various tumors. However, whether elevated expression of NF‑YA promotes a malignant phenotype in osteosarcoma (OS), and the molecular mechanisms underlying this predicted effect is currently unknown. In the present study, small hairpin RNA (shRNA)‑mediated knockdown of endogenous NF‑YA significantly inhibited the migration and invasion capabilities of OS cells in vitro, whereas ectopic expression of NF‑YA increased the migration and invasion capabilities of these cells. In addition, the induction of upregulated NF‑YA expression on the malignant phenotype of OS cells was attenuated by silencing fatty acid synthase (FASN) expression. Furthermore, the expression level of FASN was increased by upregulating NF‑YA, while decreased FASN expression was observed following NF‑YA silencing in OS cells. The results of the present study suggest that NF‑YA may promote a malignant phenotype in OS cells, in part, by activating the FASN signaling pathway, which may represent a promising target for the management of OS.

Abstract
Purpose: The purpose of this study was to investigate the profile of histone deacetylase (HDAC) activity and expression in osteosarcoma cells and tissues from osteosarcoma patients and to examine the mechanism by which a histone deacetylase (HDAC) inhibitor, Trichostatin A (TSA), promotes the apoptosis of osteosarcoma cells. Methods: HDAC activity and histone acetyltransferase (HAT) activity were determined in nuclear extracts of MG63 cells, hFOB 1.19 cells and tissues from 6 patients with primary osteosarcoma. The protein expression of Class I HDACs (1, 2, 3 and 8) and the activation of the p53 signaling pathway were examined by Western blot. Cell growth and apoptosis were determined by 3-(4, 5-dimethyl-2-thiazolyl)-2H-tetrazolium bromide (MTT) assay and flow cytometry, respectively. Results: Nuclear HDAC activity and class I HDAC expression were significantly higher in MG63 cells than in hFOB 1.19 cells, and a similar trend was observed in the human osteosarcoma tissues compared with the paired adjacent non-cancerous tissues. TSA significantly inhibited the growth of MG63 cells and promoted apoptosis in a dose-dependent manner through p53 signaling pathway activation. Conclusion: Class I HDACs play a central role in the pathogenesis of osteosarcoma, and HDAC inhibitors may thus have promise as new therapeutic agents against osteosarcoma.

Abstract
The purpose of this study was to compare and evaluate the event of VTE (Venous Thromboembolism Event) after total artificial joint replacement between two groups diagnosed with either musculoskeletal tumors or osteoarthritis (OA) of the knee. From 2004 to 2014, a total of 1,402 patients (308 in tumor group, 1,094 in OA group) were involved in this study. The rate of asymptomatic DVT (Deep vein thrombosis) was significantly higher in tumor group when compared with OA group. Though both the incidence of symptomatic DVT and PE (Pulmonary embolism) were slightly higher in tumor group, no significant difference was detected. Tumor patients suffered an almost equal risk of VTE compared with OA patients except a higher rate of asymptomatic DVT after total artificial joint replacement. For patients with tumor, no significant association was observed between any potential risk factor and DVT.

Abstract
Resecting bone tumors requires good cutting accuracy to reduce the occurrence of local recurrence. This issue is considerably reduced with a navigated technology. The estimation of extreme proportions is challenging especially with small or moderate sample sizes. When no success is observed, the commonly used binomial proportion confidence interval is not suitable while the rule of three provides a simple solution. Unfortunately, these approaches are unable to differentiate between different unobserved events. Different delta methods and bootstrap procedures are compared in univariate and linear mixed models with simulations and real data by assuming the normality. The delta method on the z-score and parametric bootstrap provide similar results but the delta method requires the estimation of the covariance matrix of the estimates. In mixed models, the observed Fisher information matrix with unbounded variance components should be preferred. The parametric bootstrap, easier to apply, outperforms the delta method for larger sample sizes but it may be time costly. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
Osteosarcoma is the most common primary bone tumor. Recent data indicated miRNAs may be involved in the pathogenesis of osteosarcoma, suggesting some novel targets for therapy. It is known that miR-429 is down-regulated and functions as a tumor suppressor by targeting c-myc and PLGG1 in gastric and breast cancer. However, the exact role of miR-429 in osteosarcoma remained unknown. In our study, we found MiR-429 was down-regulated in primary osteosarcoma lesion and osteosarcoma cell lines. Moreover, MiR-429 can inhibit the proliferation of osteosarcoma cell lines and induce more cell apoptosis. Also, we discovered MiR-429 plays a role in osteosarcoma by binding the 3'UTR of zinc finger E-box-binding homeobox 1 (ZEB1) mRNA, and that overexpression of ZEB1 could reverse the proliferation, subsequently blocking effect of miR-429. In conclusion, miR-429 serves as a tumor suppressor via interaction with ZEB1. Our finding may provide a new target for osteosarcoma therapy.

Abstract
Osteosarcoma is the most common primary malignancy to arise from bone. The pathogenesis of osteosarcoma is unclear, and new therapy molecular target is needed. The miRNAs researched suggested that miRNAs are involved in the pathogenesis of osteosarcoma. MiR-141, which belong to miR-200 family, take a part in tumorigenesis. However, the role of miR-141 in the pathogenesis of osteosarcoma remained unclear. In this study, we focused on the miR-141 in osteosarcoma and found that the expression of miR-141 is lower in osteosarcoma. Overexpression of miR-141 not only inhibits osteosarcoma cell proliferation but also induces cell apoptosis. It is estimated that miR-141 played its role via ZEB1 and ZEB2. In all, miR-141 played a osteosarcoma-suppressing role via ZEB1 and ZEB2. Our finding may elucidate the miRNAs mechanism in osteosarcoma and provide a new molecule target for osteosarcoma therapy.

Abstract
Glucocorticoid receptor DNA binding factor 1 (GRF-1) is an important Rho family GTPase-activating protein, and the dysregulation of GRF-1 expression maybe involved in tumor progression. However, the role of GRF-1 expression in the osteosarcoma prognosis has been well less elaborated. Here, we conducted a hospital-based case study, including 247 patients with pathologically confirmed osteosarcoma to evaluate the associations between GRF-1 expression and osteosarcoma prognosis. We found that high GRF-1 expression was correlated with poor outcome of osteosarcoma compared with low GRF-1 expression (the median recurrence-free survival times, 11 months vs 56 months; the median overall survival times, 18 months vs 53 months). Like tumor stage, the GRF-1 expression was an independent prognostic factor influencing the survival of osteosarcoma [hazard ratio values (95 % confidence interval) were 5.39 (3.54-8.20) for recurrence-free survival (RFS) and 6.58 (4.44-9.74) for overall survival (OS), respectively]. Furthermore, the high expression of GRF-1 was significantly associated with larger tumor size, tumor dedifferentiation, and increasing metastasis risk. Functionally, the knockdown of GRF-1 expression inhibited tumor cells proliferation and induced cell apoptosis. These results indicate for the first time that GRF-1 expression may modify osteosarcoma prognosis and may be a potential tumor therapeutic target.

Abstract
A potential complication of sarcoma excision surgery is a sensory neurological dysfunction around the surgical scar. This study utilised both objective and subjective sensation assessment modalities, to evaluate 22 patients after sarcoma surgery, for a sensory deficit. 93% had an objective sensory deficit. Light touch is less likely to be damaged than pinprick sensation, and two-point discrimination is significantly reduced around the scar. Results also show that an increased scar size leads to an increased light touch and pinprick deficit and that two-point discriminatory ability around the scar improves as time after surgery elapses. 91% had a subjective deficit, most likely tingling or pain, and numbness was most probable with lower limb sarcomas. Results also demonstrated that there were no significant relationships between any specific subjective and objective deficits. In conclusion, sensory disturbance after sarcoma surgery is common and debilitating. Efforts to minimize scar length are paramount in the prevention of sensory deficit. Sensation may also recover to an extent; thus, sensory reeducation techniques must become an integral aspect of management plans. Finally to obtain a comprehensive assessment of sensory function, both objective and subjective assessment techniques must be utilised.

Abstract
In 12 patients operated on for bone sarcoma resection, a postoperative magnetic resonance imaging of the resection specimens was obtained in order to assess the surgical margins. Margins were classified according to MRI in R0, R1, and R2 by three independent observers: a radiologist and two orthopaedic surgeons. Final margin evaluation (R0, R1, and R2) was assessed by a confirmed pathologist. Agreement for margin evaluation between the pathologist and the radiologist was perfect (κ = 1). Agreement between the pathologist and an experienced orthopaedic surgeon was very good while it was fair between the pathologist and a junior orthopaedic surgeon. MRI should be considered as a tool to give quick information about the adequacy of margins and to help the pathologist to focus on doubtful areas and to spare time in specimen analysis. But it may not replace the pathological evaluation that gives additional information about tumor necrosis. This study shows that MRI extemporaneous analysis of a resection specimen may be efficient in bone tumor oncologic surgery, if made by an experienced radiologist with perfect agreement with the pathologist.

Abstract
BACKGROUND AND AIMS MicroRNA-206 has proven to be down-regulated in many human malignancies in correlation with tumour progression. Our study aimed to characterize miR-206 contributions to initiation and malignant progression of human osteosarcoma. METHODS MiR-206 expression was detected in human osteosarcoma cell line MG63, human normal osteoblastic cell line hFOB 1.19, and paired osteosarcoma and normal adjacent tissues from 65 patients using quantitative RT-PCR. Relationships of miR-206 levels to clinicopathological characteristics were also investigated. Moreover, miR-206 mimics and negative control siRNA were transfected into MG63 cells to observe effects on cell viability, apoptosis, invasion and migration. RESULTS We found that miR-206 was down-regulated in the osteosarcoma cell line MG63 and primary tumor samples, and decreased miR-206 expression was significantly associated with advanced clinical stage, T classification, metastasis and poor histological differentiation. Additionally, transfection of miR-206 mimics could reduce MG- 63 cell viability, promote cell apoptosis, and inhibit cell invasion and migration. CONCLUSIONS These findings indicate that miR-206 may have a key role in osteosarcoma pathogenesis and development. It could serve as a useful biomarker for prediction of osteosarcoma progression, and provide a potential target for gene therapy.

Abstract
The aim of this study was to define the incidence of venous thromboembolism (VTE) and risk factors for the development of deep-vein thrombosis (DVT) after the resection of a musculoskeletal tumour. A total of 94 patients who underwent resection of a musculoskeletal tumour between January 2003 and December 2005 were prospectively studied. There were 42 men and 52 women with a mean age of 54.4 years (18 to 86). All patients wore intermittent pneumatic compression devices and graduated compression stockings. Ultrasound examination of the lower limbs was conducted to screen for DVT between the fifth and ninth post-operative days. DVT was detected in 21 patients (22%). Of these, two were symptomatic (2%). One patient (1%) had a fatal pulmonary embolism. Patients aged ≥ 70 years had an increased risk of DVT (p = 0.004). The overall incidence of DVT (both symptomatic and asymptomatic) after resection of a musculoskeletal tumour with mechanical prophylaxis was high. It seems that both mechanical and anticoagulant prophylaxis is needed to prevent VTE in patients who have undergone the resection of a musculoskeletal tumour.

Abstract
In orthopaedic surgery, resection of pelvic bone tumors can be inaccurate due to complex geometry, limited visibility and restricted working space of the pelvis. The present study investigated accuracy of patient-specific instrumentation (PSI) for bone-cutting during simulated tumor surgery within the pelvis. A synthetic pelvic bone model was imaged using a CT-scanner. The set of images was reconstructed in 3D and resection of a simulated periacetabular tumor was defined with four target planes (ischium, pubis, anterior ilium, and posterior ilium) with a 10-mm desired safe margin. Patient-specific instruments for bone-cutting were designed and manufactured using rapid-prototyping technology. Twenty-four surgeons (10 senior and 14 junior) were asked to perform tumor resection. After cutting, ISO1101 location and flatness parameters, achieved surgical margins and the time were measured. With PSI, the location accuracy of the cut planes with respect to the target planes averaged 1 and 1.2 mm in the anterior and posterior ilium, 2 mm in the pubis and 3.7 mm in the ischium (p < 0.0001). Results in terms of the location of the cut planes and the achieved surgical margins did not reveal any significant difference between senior and junior surgeons (p = 0.2214 and 0.8449, respectively). The maximum differences between the achieved margins and the 10-mm desired safe margin were found in the pubis (3.1 and 5.1 mm for senior and junior surgeons respectively). Of the 24 simulated resection, there was no intralesional tumor cutting. This study demonstrates that using PSI technology during simulated bone cuts of the pelvis can provide good cutting accuracy. Compared to a previous report on computer assistance for pelvic bone cutting, PSI technology clearly demonstrates an equivalent value-added for bone cutting accuracy than navigation technology. When in vivo validated, PSI technology may improve pelvic bone tumor surgery by providing clinically acceptable margins.

Abstract
Objective We have limited understanding on the presentation and survival of primary spinal sarcomas. The survival, recurrence rate, and related prognostic factors were investigated after treatment for primary sarcomas of the spine. Methods Retrospective analysis of medical records and radiological data was done for 29 patients in whom treatment was performed due to primary sarcoma of the spine from 2000 to 2010. As for treatment method, non-radical operation, radiation therapy, and chemotherapy were simultaneously or sequentially combined. Overall survival (OS), progression free survival (PFS), ambulatory function, and pain status were analyzed. In addition, factors affecting survival and recurrence were analyzed : age (≤42 or ≥43), gender, tumor histologic type, lesion location (mobile spine or rigid spine), weakness at diagnosis, pain at diagnosis, ambulation at diagnosis, initial treatment, radiation therapy, kind of irradiation, surgery, chemotherapy and distant metastasis. Results Median OS was 60 months, the recurrence rate was 79.3% and median PFS was 26 months. Patients with distant metastasis showed significantly shorter survival than those without metastasis. No factors were found to be significant relating to recurrence. Prognostic factor associated with walking ability was the presence of weakness at diagnosis. Conclusion Primary spinal sarcomas are difficult to cure and show high recurrence rate. However, the development of new treatment methods is improving survival.

Abstract
Introduction. Peripheral de-differentiated chondrosarcomas are among the rarest malignant mesenchymal tumors. This tumor's descriptive radiographic characteristics are reported but objective quantification does not exist. This investigation surveyed imaging of peripheral de-differentiated chondrosarcomas to facilitate better recognition of these uncommon tumors. Methods. Database interrogation for peripheral de-differentiated chondrosarcomas was performed; 23 patients were identified and imaging for 18 was reviewed. A musculoskeletal radiologist reviewed all studies for mineralization characteristics; presence of pre-existing osteochondromas; preserved corticomedullary continuity; adjacent cortical obliteration; soft-tissue mass; tumor necrosis; and presence of a cartilage cap. Tumor luminance was measured with computer software. Results. Mineralization was present in 17 tumors. Pre-existing exostoses were evident in nine cases, corticomedullary continuity was preserved in three cases. There was no difference in mineralization or other characteristics based on tumor location. Mean tumor luminance was 94.9 candela/m2. Conclusions. The imaging characteristics described for central de-differentiated chondrosarcomas are similar to the peripheral form of this tumor. Peripheral mineralization with a bimorphic pattern on CT scan and the presence of a soft-tissue mass should be considered worrisome for a peripheral de-differentiated chondrosarcoma, particularly in the setting of multiple hereditary exostoses.

Abstract
Osteosarcoma and chondrosarcoma compose most of the primary malignancies of the shoulder. The literature lacks site-specific comparative analyses of these 2 major shoulder sarcomas. The purposes of this study were to describe the different characteristics of the 2 major sarcomas near the glenohumeral joint, examine differences in treatment outcomes, and evaluate the functional outcomes of limb salvage surgery. Thirty-two patients with osteosarcoma or chondrosarcoma who underwent a wide resection including the glenohumeral joint were enrolled in this study. The characteristics of tumor development and treatment, oncologic and functional outcomes, and factors affecting outcomes were compared between groups and with the literature. The results showed shoulder osteosarcoma developing similarly to the literature reports, whereas chondrosarcoma tended to be of a high histologic grade. Nonetheless, the osteosarcoma group had a poorer overall 5-year survival rate (53.0%) than the chondrosarcoma group (85.7%) or those in previous reports. The osteosarcoma group had a tendency toward a worse 5-year metastasis-free survival rate than the chondrosarcoma group (35.4% vs 75.0%, respectively), although the 5-year local recurrence-free survival rate was not significantly different between the 2 groups (75.0% vs 87.5%, respectively). Histologic grade, surgical stage, and chemotherapy affected the oncologic outcomes in univariate analysis, although not a single factor was independent in multivariate analysis. The functional outcomes were not significantly affected by clinical characteristics or surgical methods in patients who had undergone a wide resection including the glenohumeral joint.

Abstract
BACKGROUND Resection of bone tumors within the pelvis requires good cutting accuracy to achieve satisfactory safe margins. Manually controlled bone cutting can result in serious errors, especially due to the complex three-dimensional geometry, limited visibility, and restricted working space of the pelvic bone. This experimental study investigated cutting accuracy during navigated and non-navigated simulated bone tumor cutting in the pelvis. METHODS A periacetabular tumor resection was simulated using a pelvic bone model. Twenty-three operators (10 senior and 13 junior surgeons) were asked to perform the tumor cutting, initially according to a freehand procedure and later with the aid of a navigation system. Before cutting, each operator used preoperative planning software to define four target planes around the tumor with a 10-mm desired safe margin. After cutting, the location and flatness of the cut planes were measured, as well as the achieved surgical margins and the time required for each cutting procedure. RESULTS The location of the cut planes with respect to the target planes was significantly improved by using the navigated cutting procedure, averaging 2.8 mm as compared to 11.2 mm for the freehand cutting procedure (p < 0.001). There was no intralesional tumor cutting when using the navigation system. The maximum difference between the achieved margins and the 10-mm desired safe margin was 6.5 mm with the navigated cutting process (compared to 13 mm with the freehand cutting process). CONCLUSIONS Cutting accuracy during simulated bone cuts of the pelvis can be significantly improved by using a freehand process assisted by a navigation system. When fully validated with complementary in vivo studies, the planning and navigation-guided technologies that have been developed for the present study may improve bone cutting accuracy during pelvic tumor resection by providing clinically acceptable margins.

Abstract
microRNAs are involved in different cancer-related processes. miR-195, one of the miR-16/15/195/424/497 family members, has been shown to act as a tumor suppressor during tumorigenesis. However, the function of miR-195 in osteosarcoma is still unclear. In our study, the miR-195 expression level was upregulated in osteosarcoma cells, by transfection with miR-195, and the fatty acid synthase (FASN) mRNA and protein expression levels were measured by RT-PCR and western blotting. Cell migration and invasion was measured using wound healing migration and Transwell invasion assays. We found that the upregulation of miR-195 greatly decreased cell invasion and the migration of U2OS. We also identified that FASN may be a direct target of miR-195 by the luciferase activity assay. These findings provide evidence that miR-195 plays a key role in inhibiting osteosarcoma cell migration and invasion through targeting FASN, and strongly suggest that exogenous miR-195 may have therapeutic value in treating osteosarcoma.

Abstract
Osteosarcoma, a common malignancy primarily affecting children, generally has a poor prognosis. Novel diagnostic, prognostic and therapeutic markers are required to ameliorate the negative outcomes of this disease. We investigated two potential markers, WNT-5a and ROR2, which are hypothesized to dysregulate WNT signaling pathways to promote tumorigenesis in other types of cancer. We investigated WNT-5a and ROR2 expression using immunohistochemistry in 42 osteosarcoma and 12 osteochondroma specimens, and compared the expression of these proteins with one another as well as with clinicopathological parameters. WNT-5a was detected in 34/42 (81.0%) cases and ROR2 was detected in 31/42 (73.8%) cases, significantly higher than in osteochondroma (16.7 and 25.0%, respectively; both P<0.05). Expression of these proteins was positively correlated (r=0.552, P<0.05). Furthermore, expression of WNT-5a and ROR2 was both correlated with Enneking surgical stage and tumor metastasis (P<0.05), but not with patient gender, age or pathological type. Thus, WNT-5a and ROR2 were more highly expressed in more severe disease states, and therefore may play a coordinated role in the occurrence and progression of osteosarcoma.

Abstract
Primary malignant bone tumors are rare and account for about 6% of all new pediatric cancer cases per year in the United States. Identification of the lesion not uncommonly occurs as a result of imaging performed for trauma. Clinical and standard imaging characteristics of the various tumor types are evolving in concert with treatment advancements and clinical trial regimens. This article reviews the 3 most common pediatric bone sarcomas-osteosarcoma, Ewing sarcoma, and chondrosarcoma-and their imaging as applicable to contemporary disease staging and monitoring, and explores the roles of evolving imaging techniques.

Abstract
Treating metastatic osteosarcoma (OS) remains a challenge in oncology. Current treatment strategies target the primary tumour rather than metastases and have a limited efficacy in the treatment of metastatic disease. Metastatic cells have specific features that render them less sensitive to therapy and targeting these features might enhance the efficacy of current treatment. A detailed study of the biological characteristics and behaviour of metastatic OS cells may provide a rational basis for innovative treatment strategies. The aim of this review is to give an overview of the biological changes in metastatic OS cells and the preclinical and clinical efforts targeting the different steps in OS metastases and how these contribute to designing a metastasis directed treatment for OS.

Abstract
Metastatic skeletal adenocarcinoma is an all too common and unfortunate complication of advanced oncologic states. Mortality rates are usually elevated when bony metastasis are evident, as this signifies advanced disease. The foot and ankle are uncommon sites for metastatic deposits, but may occur. As such, the foot and ankle surgeon must be aware of the potential for such disease, and be able to proceed with an imaging and medical work-up of the patient with foot and ankle skeletal metastasis. The goal of treatment is pain relief and the preservation of functional ambulation, which may greatly enhance the quality of remaining life for patients. A team approach is mandatory to manage the patients with metastatic disease. We present a case of an elderly male with a known history of prostate cancer, who presented with unrelenting heel pain, which upon diagnostic work-up, proved to be progressive calcaneal as well as axial metastasis after a brief period of clinical remission. Operative management coupled with palliative radiation and bisphosphonate therapy provided symptomatic pain relief and maintenance of functional ambulation.
