Abstract
BACKGROUND Known risk factors (surgical margin, tumor necrosis) of local recurrence (LR) in osteosarcoma are determined by results available after surgery. However, relations between preoperative characteristics and LR have not been clearly defined. METHODS We compared the clinicopathologic characteristics of 36 osteosarcoma patients with LR and 394 patients without LR after surgery. In addition, prognostic variables were evaluated to establish factors could influence LR. RESULTS Compared to the non-LR group, the LR group showed an increase in tumor volume ratio (TVR) during preoperative chemotherapy (P < 0.01), inadequate surgical margin (P < 0.01), and poor histologic response (P < 0.01). Univariate analysis of data from 430 patients revealed that an increased TVR (P < 0.01), inadequate surgical margin (P < 0.01), poor histologic response (P < 0.01), and nonosteoblastic pathologic subtype (P = 0.04) were negatively related to LR-free survival. In multivariate analysis, an elevated TVR (P < 0.01, relative risk = 10.26) and inadequate surgical margin (P < 0.01, relative risk = 5.91) emerged as the key prognostic factors for LR. CONCLUSIONS A TVR increase during preoperative chemotherapy could be used to predict patients at high risk of LR. This finding might be useful when considering surgical options to decrease the risk of LR.

Abstract
These guidelines have been developed in order to provide an overview and a set of broad-based key recommendations for the management of patients with bone sarcomas in the UK. They have taken into consideration the most up-to-date scientific literature along with the recent recommendations by the European Society of Medical Oncology. The principles of the NICE guidance on both "improving outcomes for patients with sarcomas" and "improving outcomes with children and young people with cancer" have been incorporated. As care evolves, it is acknowledged that these guidelines will need updating. The key recommendations are that bone pain or a palpable mass should always lead to further investigation and patients with clinicoradiological findings suggestive of a primary bone tumour should be sent to a reference centre. Patients should then have their care managed at such a specialist centre by a fully accredited multidisciplinary team.

Abstract
Pulmonary metastasectomy is a curative option for selected patients with cancer spread to the lungs. Complete surgical removal of pulmonary metastases can improve survival and is recommended under certain criteria. Specific issues that require consideration in a multidisciplinary setting when planning pulmonary metastasectomy include: adherence to established indications for resection, the surgical strategy including the use of minimally invasive techniques, pulmonary parenchyma preservation, and the role of lymphadenectomy.

Abstract
PURPOSE Osteosarcoma most commonly recurs in the lung. Based on preliminary data on the antitumor effects of granulocyte-macrophage colony stimulating factor (GM-CSF) in animal models, and promising phase I trials, we embarked on a feasibility study of inhaled GM-CSF in patients with first isolated pulmonary recurrence of osteosarcoma. EXPERIMENTAL DESIGN Forty-three eligible patients received inhaled GM-CSF at doses from 250 to 1,750 microg twice daily on alternate weeks. Following two cycles, patients underwent thoracotomy to resect tumor and analyze pulmonary nodules for expression of Fas/Fas ligand (Fas/FasL), and the presence of dendritic cells by immunostaining for CD1a, clusterin, and S100. Following surgery, patients received 12 additional cycles of therapy on alternating weeks or until progression. Event-free survival and survival, and feasibility of therapy delivery were evaluated. RESULTS Dose escalation to 1,750 microg twice daily was feasible with no dose-limiting toxicity. Mean scores for Fas/FasL in nodules from patients with bilateral recurrence who underwent unilateral thoracotomy pretreatment (using a scoring system of 0-3) were 1.3 and 0.88, respectively, compared with 0.78 and 0.62 in nodules resected following two cycles of therapy. Only 11 of 30 nodules postinhalation were positive for CD1a, 4 of 30 for S100, and 6 of 30 for clusterin. Event-free and overall survival at 3 years were 7.8% and 35.4%, respectively. CONCLUSIONS Inhalation of GM-CSF at doses from 250 to 1,750 microg twice daily on alternate weeks was feasible with low toxicity. However, no detectable immunostimulatory effect in pulmonary metastases or improved outcome postrelapse was seen.

Abstract
It has been reported that the progression of osteosarcoma was closely associated with the aberrant activation of canonical Wnt signaling. Wnt inhibitory factor-1 (WIF-1) is a secreted Wnt inhibitor whose role in human osteosarcoma remains unknown. In this study, WIF-1 expression in NHOst and osteosarcoma cell lines was determined by real-time reverse transcription-PCR, methylation-specific PCR, and Western blotting analysis. In addition, tissue array from patient samples was examined for WIF-1 expression by immunohistochemistry. Compared with normal human osteoblasts, WIF-1 mRNA and protein levels were significantly downregulated in several osteosarcoma cell lines. The downregulation of WIF-1 mRNA expression is associated with its promoter hypermethylation in these tested cell lines. Importantly, WIF-1 expression was also downregulated in 76% of examined osteosarcoma cases. These results suggest that the downregulation of WIF-1 expression plays a role in osteosarcoma progression. To further study the potential tumor suppressor function of WIF-1 in osteosarcoma, we established stable 143B cell lines overexpressing WIF-1. WIF-1 overexpression significantly decreased tumor growth rate in nude mice as examined by the s.c. injection of 143B cells stably transfected with WIF-1 and vector control. WIF-1 overexpression also markedly reduced the number of lung metastasis in vivo in an orthotopic mouse model of osteosarcoma. Together, these data suggest that WIF-1 exerts potent antiosteosarcoma effect in vivo in mouse models. Therefore, the reexpression of WIF-1 in WIF-1-deficient osteosarcoma represents a potential novel treatment and preventive strategy.

Abstract
BACKGROUND Osteosarcoma (OS) is the most common primary bone tumour in children and young adults. Despite improved prognosis, metastatic or relapsed OS remains largely incurable and no significant improvement has been observed in the last 20 years. Therefore, the search for alternative agents in OS is mandatory. RESULTS We investigated phospho-ERK 1/2, MCL-1, and phospho-Ezrin/Radixin/Moesin (P-ERM) as potential therapeutic targets in OS. Activation of these pathways was shown by immunohistochemistry in about 70% of cases and in all OS cell lines analyzed. Mutational analysis revealed no activating mutations in KRAS whereas BRAF gene was found to be mutated in 4/30 OS samples from patients. Based on these results we tested the multi-kinase inhibitor sorafenib (BAY 43-9006) in preclinical models of OS. Sorafenib inhibited OS cell line proliferation, induced apoptosis and downregulated P-ERK1/2, MCL-1, and P-ERM in a dose-dependent manner. The dephosphorylation of ERM was not due to ERK inhibition. The downregulation of MCL-1 led to an increase in apoptosis in OS cell lines. In chick embryo chorioallantoic membranes, OS supernatants induced angiogenesis, which was blocked by sorafenib and it was also shown that sorafenib reduced VEGF and MMP2 production. In addition, sorafenib treatment dramatically reduced tumour volume of OS xenografts and lung metastasis in SCID mice. CONCLUSION In conclusion, ERK1/2, MCL-1 and ERM pathways are shown to be active in OS. Sorafenib is able to inhibit their signal transduction, both in vitro and in vivo, displaying anti-tumoural activity, anti-angiogenic effects, and reducing metastatic colony formation in lungs. These data support the testing of sorafenib as a potential therapeutic option in metastatic or relapsed OS patients unresponsive to standard treatments.

Abstract
Osteosarcoma, the most common bone sarcoma, affects approximately 560 children and adolescents annually in the United States. The incidence of new diagnoses peaks in the second decade of life. Twenty percent of patients present with clinically detectable metastases, with micrometastases presumed to be present in many of the remaining patients. Treatment typically includes preoperative chemotherapy, surgical resection, and postoperative chemotherapy. Limb-salvage procedures with wide surgical margins are the mainstay of surgical intervention. Advances in chemotherapy protocols have led to a 5-year survival rate of 60% to 78%. Among the goals of future treatment regimens are improved chemotherapeutic agents with higher specificity and lower toxicity.

Abstract
BACKGROUND A phase 2 trial was carried out to assess the antineoplastic activity of 2 courses of cyclophosphamide-etoposide in relapsed osteosarcoma patients. METHODS Twenty-six relapsed osteosarcoma patients with a median age of 18.5 years (8.3-47.1) were enrolled. Seven patients were in first relapse (27%), 11 in second relapse (42%), 7 in third relapse (27%), and 1 in fourth relapse (4%). Eighteen patients had bone metastasis at study entry (69%). Cyclophosphamide was given at 4 g/m(2) on Day 1 followed by etoposide at 200 mg/m(2) on Days 2, 3, and 4. Second cyclophosphamide and etoposide was planned at 21 days to 28 days from the previous one. The primary endpoint of the study was the clinical benefit at 4 months measured as progression-free survival. RESULTS Progression-free survival at 4 months was 42%. Five patients achieved responses (19%), 9 patients had stable disease (35%), and 12 had tumor progression (46%). Overall survival (OS) at 1 year was 50%. The only grade 4 extrahematological toxicities were fever (5%), acute bronchospasm (4%) and stomatitis (18%). Six patients (23%) underwent radical surgery after cyclophosphamide and etoposide x2. CONCLUSIONS Cyclophosphamide and etoposide x2 may arrest osteosarcoma progression in a significant number of patients (54%). Osteosarcoma progression arrest after cyclophosphamide and etoposide x2 translates in a better OS. Cyclophosphamide and etoposide x2 had good tolerability and the toxicity was time-limited and resolved in all cases.

Abstract
PURPOSE OF REVIEW Osteosarcoma and Ewing's sarcoma are the two most common primary malignant bone tumors in children and account for approximately 6% of all childhood malignancies. Treatment methods have seen significant advancements, particularly in regard to chemotherapy and limb-sparing surgery. These advancements have led to increased survival rate. With many long-term survivors, it is important to evaluate long-term patient outcomes following treatment, including function and health-related quality of life. We will review the current trends in treatment of these diseases, different reconstructive options available, and the methods and results for evaluating the long-term results. RECENT FINDINGS There have been many improvements in the medical treatment of these tumors leading to increasing long-term survival. There have also been improvements in reconstructive techniques for the maintenance of functional extremities in these patients. Newer evaluation methods for both functional outcome and health-related quality of life measures that are more specific to children and adolescents are being developed and in use. SUMMARY This report will provide an overview of the current treatment options and long-term complications in primary malignant bone tumors for the pediatrician caring for a child with these problems.

Abstract
Patients with suspected or confirmed osteosarcoma should be evaluated and treated at a comprehensive cancer center within a multidisciplinary sarcoma program that includes pediatric, medical and radiation oncologists, orthopedic and surgical oncologists, musculoskeletal pathologists, and radiologists. Successful treatment involves proper diagnosis, neoadjuvant and adjuvant multi-agent chemotherapy, and aggressive surgery with an emphasis toward limb-preserving procedures. Treatment of osteosarcoma should be undertaken within the framework of large cooperative group clinical trials for children, adolescents, and adults. Patients treated with osteosarcoma should be followed closely both for recurrence of disease and for development of late effects of the treatment of their cancer. The treatment of metastatic, recurrent and/or refractory disease is more controversial. Despite advances in systemic treatment, surgical technique, and supportive care, the overall outcome is still poor.

Abstract
BACKGROUND Survival data are still limited and controversial about adult patients with osteosarcoma as older group of patients has mostly been excluded from the historical trials. PATIENTS AND METHODS Patients with osteosarcoma, from 1986 to 2003, in a single center, were reviewed. Survival according to a cutoff age of 40 was studied. Patients with lung metastases were identified. Variables at first lung involvement including time to first lung metastases, multiplicity and size of the metastatic lesions and use of chemotherapy were all analyzed. RESULTS A total of 247 patients, with age range of 14-77 years, were reviewed. Five-year survival is 66% with no difference between patients <40 or >or=40 years. Eighty-five patients, with either synchronous or metachronous lung involvement, have 3-year postlung metastases survival (PLMS) of 30%. Forty-seven patients (55.3%) underwent lung resection with 3-year PLMS of 38% compared with 16% for nonoperated patients (P = 0.00023). Patients who developed lung metastases within a year and have fewer than four lung lesions have better PLMS (P < 0.0001 for both). CONCLUSIONS Older patients have identical survival to pediatric population and should have a similar management approach. Complete metastectomy is the key issue for prolonged survival. Time to lung metastases and number of lung lesions are the most important prognostic factors.

Abstract
The Bone Tumor Center of the "Istituto Ortopedico Rizzoli" was established in 1955 with the aim of studying and treating the musculoskeletal tumors. Between 1959 and 2006, 1245 patients with high grade nonmetastatic osteosarcoma of the extremity were treated at our Institute. Most of them were enrolled in study protocols. In the "prechemotherapy era", the cure rate was 11%, with an amputation rate of 90%. Our first experience with adjuvant chemotherapy was in 1972. A total of 223 patients received adjuvant chemotherapy, with a disease-free survival (DFS) ranging from 45% to 53%, according to the chemotherapy protocol used. With the introduction of neoadjuvant chemotherapy, the resection rate increased and reached 94%, when high dose fosfamide was added to standard doses of methotrexate, cisplatin, and adriamycin. In the last few years, the results of treatment of nonmetastatic osteosarcoma of the extremity have reached a plateau (64% five-year DFS), and strategies of dose intensification are not able to improve the prognosis. Not only new active drugs, but also different approaches to the disease, are needed. In this regard, we are now investigating tumor microenvironment-targeted agents and chemotherapy protocols based on prospective biological stratification of patients. Collaborative projects with international groups and institutions are crucial for this rare disease.

Abstract
Between January 1990 and December 2006, 123 patients<or=16 years with the histopathologic diagnosis of osteosarcoma were treated with a chemotherapy regimen comprising epirubicin, cisplatin, and ifosfamide. The mean follow-up time was 36 months (range 2-219 months). Among the 94 patients analyzed, 68 patients (72.3%) were alive at the time of the analysis. A total of 26 patients (13 each with nonmetastatic and metastatic disease) died; 20 of these (9 with nonmetastatic disease and 11 with metastatic disease) died of disease; 5, of chemotherapy toxicity, and 1, of nonmetastatic disease from acute nonlymphoid leukemia 13 months following the cessation of osteosarcoma therapy. The estimated 5- and 10-year Overall Survival (OS) rates for all patients were 64.7% (95% confidence interval [95% CI] 74.8-52.94%) and 62.2% (95% CI 74.6-49.9%), respectively. The Event Free Survival (EFS) rate for all patients was 51.8% (95% CI 40.2-63.4%) at both 5 and 10 years. The estimated 5- and 10-year Overall Survival (OS) rates for patients with nonmetastatic disease were 78.3% (95% CI 66.9-89.7%) and 75.1 (95% CI 62.6-87.6%), respectively; this 5-year rate was significantly superior to that of patients with metastatic disease, 13.5% (95% CI 0-30.8%) (p<0.001). The estimated EFS rate for patients with nonmetastatic disease was 62.4% (95% CI 49.9-79.9%) at both 5 and 10 years and was significantly better than the 5-year EFS of 6.9% (95% CI 0-19.9%) in patients with metastatic disease (p<0.001). Progression during preoperative chemotherapy was encountered in 18 patients (19.1%), 11 of whom had metastatic disease at diagnosis. Four patients (three with nonmetastatic disease and one with metastatic disease) underwent salvage treatment consisting of early surgical intervention and preoperative radiation. The estimated 5- and 10-year OS rates were 13% (95% CI 0-29.7%) for patients who had progression during treatment; this rate was significantly inferior to both the 5- and 10-year OS rates for patients without progressive disease, which were 78.2% (95% CI 66.1-90.4%) and 75% (95% CI 61.9-83.1%), respectively (p<0.001). A total of 33 patients experienced relapse and/or progression at a median time of 9 months (range 0-40 months). Histologic response (<90% necrosis vs. >or=90%) was significantly correlated with the 5-year EFS (31% vs. 67.6%, respectively, p=0.023) but not with OS (57.7% vs. 76.5%, respectively, p=0.13). The presence of metastases at diagnosis was found to be the most significant single characteristic influencing the outcome. The rate of histologically good response to preoperative chemotherapy was 64.5%, which is comparable with the 28-85% response rates given in the literature. Our results demonstrate that the combination of epirubicin, cisplatin, and ifosfamide is an active and reasonably well-tolerated regimen for childhood osteosarcoma.

Abstract
The management of pulmonary metastases poses a challenge to the multidisciplinary team involved in the treatment of osteosarcoma. A postal survey on the management of pulmonary metastases in osteosarcoma involving 17 representatives from international study groups and selected institutions was performed in which a response rate of 94% was achieved. The results showed uniform approaches in areas like the imaging methods used for initial staging and the use of manual exploration with thoracotomy. However, it demonstrated diverse practices regarding exploration of the unaffected site in unilateral pulmonary disease, and the approach to lesions disappearing under chemotherapy. Furthermore, agreement on the size of a lesion considered to distinguish between benign and of metastatic origin, varied. Based on the survey and a review of the current literature, detection methods and principles of multimodal therapy will be discussed. Prognostic factors in synchronous and metachronous pulmonary metastases and their implications for a multimodal therapy is also presented.

Abstract
PURPOSE To evaluate patient and tumor characteristics, treatment, and outcomes in a large cohort of unselected patients with second and subsequent recurrences of osteosarcoma. PATIENTS AND METHODS Two hundred forty-nine consecutive patients who had originally received combined-modality therapy on neoadjuvant Cooperative Osteosarcoma Study Group protocols and went on to develop a total of 409 second and subsequent osteosarcoma recurrences were analyzed for patient-, tumor-, and treatment-related factors and outcomes. RESULTS Five-year overall and event-free survival rates were 16% and 9% for 249 second, 14% and 0% for 93 third, 13% and 6% for 38 fourth, and 18% and 0% for 14 fifth recurrences, respectively. The proportion of recurrences confined to the lungs decreased and the proportion of those with chest wall involvement increased with increasing numbers of recurrences. The duration of relapse-free intervals and the number of lesions at recurrence correlated with outcomes. While only one of 205 patients with rerecurrence survived past 5 years without surgical remission, 5-year overall and event-free survival rates were 32% and 18% for 119 second, 26% and 0% for 45 third, 28% and 13% for 20 fourth, and 53% and 0% for five fifth recurrences, respectively, in which a renewed surgical remission was achieved. The use of chemotherapy correlated with longer survival in patients without surgical remissions. CONCLUSION To our knowledge, this is the first report of survival estimates derived from large cohorts of unselected patients with second and subsequent osteosarcoma recurrences. It confirms the overwhelming importance of surgical clearance. Prognostic indicators after rerecurrences resemble those known from first recurrence. The exact role of re-treatment with chemotherapy, particularly in the adjuvant situation, remains to be defined.

Abstract
Osteosarcoma is the most common malignant primary bone tumor in children and adolescents. Current optimal treatment for osteosarcoma consists of multi-agent chemotherapy and aggressive surgical resection of all sites of disease involvement. The current national and international cooperative trial for patients with newly diagnosed osteosarcoma builds upon the backbone of cisplatin, doxorubicin, and methotrexate. This protocol is designed to clarify whether (i) the addition of ifosfamide and etoposide to postoperative chemotherapy with cisplatin, doxorubicin, and methotrexate improves the event-free survival and overall survival for patients with resectable osteosarcoma and a poor histologic response to 10 weeks of preoperative chemotherapy; and (ii) the addition of pegylated interferon-alpha-2b as maintenance therapy after postoperative chemotherapy with cisplatin, doxorubicin, and methotrexate improves the event-free survival and overall survival for patients with resectable osteosarcoma and a good histologic response to 10 weeks of preoperative chemotherapy. However, the optimal treatment strategy (or strategies) for patients with relapsed or metastatic disease has yet to be defined. This remains one of the persistent challenges in the treatment of osteosarcoma. Recent therapeutic advances have focused on circumventing chemotherapy resistance mechanisms, incorporation of non-classical agents into upfront therapy, targeting of the tumor micro-environment, and investigating the role of novel delivery mechanisms. In patients with localized disease the 5-year survival rate is at least 70%; patients with metastatic or recurrent disease have <20% chance of long-term survival despite aggressive therapies. These figures have changed little in the past 2 decades. This review focuses on the current therapy for osteosarcoma, and highlights emerging strategies that will hopefully change the outlook for patients with this disease.

Abstract
Osteosarcoma is the most common primary bone tumor in childhood and adolescence. The use of combination chemotherapy and surgery enables long-term survival in approximately 60-70% of cases. However, the necessity for surgery, the poor prognosis of patients with metastatic or recurrent disease (long-term survival in only about 20% of cases), and the lack of establishment of second-line chemotherapy suggest that improvements in chemotherapy are desperately needed. Currently, in an effort to extend the protocol with the chemotherapy drugs that already exist, high-dose chemotherapy with/without autologous peripheral blood stem cell transplantation, and tumor-targeted drug delivery systems are under investigation. Future drug developments will no doubt lie in the direction of immunotherapy and anti-angiogenic therapy, as well as the use of cytotoxic drugs. Identifying the genes and signal transduction pathways responsible for the development of osteosarcoma or for the occurrence of malignancy in cases of osteosarcoma will undoubtedly lead to the identification of pathway-specific agents, or possible gene therapy. Furthermore, as increased light is shed on the character of osetoblastic differentiation in osteosarcoma, this will certainly give rise to new treatments utilizing differentiation therapy. This article reviews the current status and perspectives regarding the treatment of osteosarcoma in terms of chemotherapy.

Abstract
Over the past 30 years, a significant improvement in the prognosis of localized osteosarcoma of the extremities has been observed. Despite these results, approximately 30-40% of patients will relapse, mostly within the first 3 years from diagnosis. The prognosis of patients with recurrent disease or metastases at diagnosis is poor. To improve the survival in this patient population, several attempts have been made. An increased dose intensity of chemotherapy induces short lasting remission but does not increase the survival. In the era of targeted therapy, few drugs have been tested with dismal results. The use of biological agents endowed with immunomodulant activity (that is IL-2) or reduced-intensity allogeneic hemopoietic SCT has produced intriguing results that need further confirmation. In this context, an ongoing study explores the antitumor activity of specific T-cytotoxic lymphocytes.

Abstract
The presence of distant metastases usually implies disease not amenable to cure through surgical resection. In such cases, chemotherapy is the mainstay of treatment, with surgery or radiation reserved for palliative measures. However, metastases limited to the lung may be resected with resultant prolonged patient survival compared to unresectable, widely disseminated metastases. Isolated pulmonary metastases should therefore not be considered untreatable. In this review, we discuss the pathophysiology of pulmonary metastases. We outline prognostic factors associated with metastases, and propose criteria to help select patients for metastasectomy. Surgical approaches, including various open techniques and video-assisted thoracoscopy, are covered. Surgical issues, including the need for unilateral versus bilateral exploration, the extent of resection to achieve cure, the need for lymph node dissection, and the benefit of repeat operations, are discussed. Finally, we review some of the more common tumors that metastasize to the lungs, and the role of metastasectomy in their treatment. Resection of pulmonary metastases confers a survival benefit to a select group of patients so long as the primary tumor is controlled, metastases are limited to the lungs, the patient can tolerate the operation from a cardiopulmonary standpoint, and the metastases are completely resected.

Abstract
OPINION STATEMENT Bone tumors, particularly osteosarcomas and members of the Ewing Sarcoma Family of Tumors (ESFT), are typical malignancies of adolescents and young adults. Current diagnostic and therapeutic guidelines for patients of all ages were developed in this specific age group. The aim of bone sarcoma therapy should be to cure the patient from both the primary tumor and all (micro-)metastatic deposits while maintaining as much (extremity) function and causing as few treatment-specific late effects as possible. Bone sarcoma therapy requires close multidisciplinary cooperation. Usually, it consists of induction chemotherapy, followed by local therapy of the primary tumor (and, if present, primary metastases) and further, adjuvant chemotherapy. Local treatment for osteosarcoma should be surgery whenever feasible. Surgery is also gaining importance in ESFT, which was long considered a domain of radiotherapy. Modern reconstructive techniques continue to expand the indications for limb salvage, particularly for patients who have not yet reached skeletal maturity. Treatment within the framework of prospective, multi-institutional trials should be considered standard of care not only for children, but also for affected adolescents and (young) adults. Such trials are essential in guaranteeing that all patients have access to appropriate care and that progress from biological studies can be translated into prognostic improvements without undue delay. The rarity of bone sarcomas increasingly requires trials to be multinational.

Abstract
AIM To characterize and compare the different biological behaviors of 2 novel human osteosarcoma cell lines, Zos and Zos-M, established respectively from the primary tumor and the skip metastasis of an osteosarcoma patient. METHODS In vitro studies included morphological observations, karyotype analysis, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide cell proliferation assay, and cell sensitivity to chemotherapeutic drugs. Subcutaneous and intravenous inoculations into nude mice were carried out to study the tumorigenicity and the metastatic potential. RT-PCR was performed to assess the expression of the osteoblastic markers and some metastasis-related genes. RESULTS Both cell lines remained stable for more than 100 passages in vitro without interruption. The RT-PCR examination indicated that they retained the molecular characteristics of an osteoblastic lineage. The karyotype analysis displayed aneuploidy and various structural abnormalities. Both cell lines are tumorigenic; Zos-M differs from Zos by the former's ability to develop lung metastasis after intravenous injection. The comparison of the expression patterns of some metastasis-related genes revealed that the decreased expression of cadherin-11 in Zos-M may correlate with a high potential of metastases. Moreover, both cell lines are less sensitive to the current chemotherapy protocols. CONCLUSION The establishment of osteosarcoma cell lines, Zos and Zos-M, and related animal models provide a useful resource for studying the aggressive behavior of osteosarcoma and will be helpful for screening effective treatment strategies.

Abstract
Despite comprehensive management of pediatric sarcomas, only 60% to 70% of children become long-term survivors. This study was undertaken to evaluate whether regular follow-up improves overall survival of children with recurrent sarcomas. The medical charts of 107 children diagnosed with soft tissue and bone sarcomas were reviewed, of whom 29 relapsed. They were divided into 2 groups according to the way of relapse diagnosis: due to complaints/physical examination (14) or on routine imaging studies (15). All were followed by regular physical examination and imaging studies (chest computed tomography, magnetic resonance imaging, and bone scan/positron emission tomography-computed tomography scan with fluorodeoxyglucose) at regular intervals. Analysis of the results showed that (1) regular imaging studies do not facilitate earlier recognition of relapse in children with sarcomas; (2) regular follow-up with imaging studies does not influence overall survival of children with sarcomas; (3) other diagnostic and treatment approaches are needed to improve the survival of children with recurrent sarcomas.

Abstract
Multimodal therapies play important roles in the treatment of osteosarcoma (OS) and Ewing's family of tumors (EFTs), two most frequent malignant bone tumors. Although the clinical outcome of primary OS and EFTs is greatly improved, the relapsed cases often are associated with multidrug resistance of the tumors and the prognosis of these patients is still poor. Flavopiridol, a pan cyclin-dependent kinase (CDK) inhibitor is a novel antitumor agent that can induce cell cycle arrest and apoptosis in many cancer cells. However, there have been no studies about the effects of flavopiridol on drug-resistant OS and EFTs. Here, we demonstrated that flavopiridol induced the cleavage of poly-ADP-ribose polymerase (PARP) in a time and dose dependent manner in adriamycin-resistant OS and EFTs cells expressing P-glycoprotein (P-gp) and multidrug resistance-associated protein 1 (MRP(1)) as effectively as in their parental cells. Our data also showed that flavopiridol caused the release of mitochondrial cytochrome c and the activation of caspase-9, caspase-8 and caspase-3, with an increase ratio of the proapoptotic protein level (Bax) to the antiapoptotic protein level (Bcl-2 and Bcl-X(L)), while apoptosis was inhibited by pan caspase inhibitor (Z-VAD-FMK) and caspase-3 inhibitor (Z-DEVD-FMK), not by caspase-8 inhibitor (Z-IETD-FMK). The treatment with flavopiridol further inhibited the tumor growth in mouse models of the drug-resistant OS and EFTs. These results suggest that flavopiridol might be promising in clinical therapy for the relapsed OS and EFTs.

Abstract
Numerous studies have demonstrated a correlation between hyaluronan expression and the malignant properties of various kinds of cancer, and inhibition of hyaluronan production causes decreased tumor growth. Hyaluronan oligosaccharides have been shown to inhibit several tumor cell types via disruption of receptor-hyaluronan interaction. However, few studies have addressed hyaluronan with respect to osteosarcoma. In this study, we examined the effects of exogenously added hyaluronan oligosaccharides on tumorigenicity of murine osteosarcoma cells, LM-8, and human osteoblastic osteosarcoma cells, MG-63. Moreover, the critical size of oligomers needed to inhibit malignant properties was defined. Fluorescent hyaluronan oligosaccharides accumulated both on the surface of cells and in the cytoplasm, and this retention was blocked by pretreatment with an anti-CD44 monoclonal antibody. Hyaluronan octasaccharides significantly inhibited cell viability and induced apoptosis as defined by cell proliferation and terminal deoxynucleotidyl transferase dUTP nick-end labeling assays, respectively. Octasaccharides also abrogated functional cell-associated matrices and significantly reduced the retention of endogenous hyaluronan. Further, octasaccharide treatment affected an inhibition of cell motility as well as cell invasiveness. Pretreatment of the cells with anti-CD44 antibody reduced the antitumor effect of the octasaccharides. In vivo, intratumoral injection of hyaluronan octasaccharides reduced the hyaluronan accumulation in local tumors, resulting in significant suppression of the formation of distant lung metastasis. Together these data suggest that hyaluronan oligosaccharides have potent antitumor effects functioning in part by the abrogation of hyaluronan-rich cell-associated matrices.

Abstract
INTRODUCTION There have been no large-scale studies reporting the outcome of patients with osteosarcoma who first relapse with bone metastases, but there have been several case reports describing a much poorer prognosis for these patients than for those who relapse with lung metastases. METHODS We compared 52 patients with skeletal metastases as first relapse after neoadjuvant or adjuvant treatment for osteosarcoma of the extremity given at our institution between 1972 and 1999 with 371 contemporary patients treated with the same chemotherapy protocols, who first relapsed with lung metastases. RESULTS We found that the 52 patients with bone metastases had a higher rate of local recurrences (36% vs. 6%), a lower rate of remission (35% vs. 77%), and lower rates of 5-year event-free survival (11% vs. 27%) and overall survival (13% vs. 31%) (p < 0.01 for all comparisons). INTERPRETATION The prognosis of patients who relapse with bone metastases--unless they have a single late-appearing metastasis--is worse than the prognosis of patients who first relapse with lung metastases. There was no difference in outcome between patients with single, resectable and late-appearing skeletal metastases and patients relapsing in the lung.

Abstract
BACKGROUND Local recurrence in osteosarcoma is clinically distinct from metastasis, although associated with a similar reduction in survival. The prognostic factors in locally recurrent osteosarcoma were investigated and these factors were translated into a management strategy. METHODS In all, 407 consecutive patients with skeletal osteosarcoma between 1977 and 2002 were analyzed. Twenty-three patients with resectable local recurrence were analyzed. Clinical and tumor-related factors were assessed for significance in relation to survival and a management strategy was formulated based on factors found to be independently significant for survival. RESULTS Seventeen of the 23 patients underwent primary resections and initial treatment, yielding an overall local recurrence rate of 4.2% for resectable cancer. Median time to local recurrence was 13 months (95% confidence interval, 9-16 months). The 5-year and 10-year survival rates in the recurrent cases were 29% and 10%, respectively. All patients received chemotherapy both for their primary and recurrent disease. Increased risk of local recurrence (P < .0001) was strongly correlated with positive margins of resection. The rate of local recurrence was not related to chemotherapy-associated necrosis in the primary tumor. Nevertheless, neoadjuvant therapy halved the risk of local recurrence (odds ratio, 1.92; P = .3, power 10%). The strongest correlate with poor survival was local recurrence within the first year after primary resection (P = .001), followed by metastasis at the time of first local recurrence (P = .04) and failure to achieve clinical remission after disease recurrence (P = .04). Chemotherapy-associated necrosis and margins of resection of the primary tumor were not significant prognostic variables for survival. Survival differed significantly among patients defined by local disease-free interval and lung metastasis (P = .0001). They required an individualized approach as captured in the management algorithm. CONCLUSION There is a residual risk of local recurrence in patients despite favorable chemotherapy-associated necrosis and negative margins of resection. A treatment strategy emphasizing clinical remission at all identifiable sites offers the highest likelihood of survival in this patient population.

Abstract
The current combination treatment, chemotherapy and surgery, has significantly improved the cure rate and the survival rate of primary bone osteosarcoma. The 5-year survival rate has increased in the last 30 years from 10% to 70%. Even in patients with poor prognosis, such as those with metastases at diagnosis, the 5-year survival rate has reached 20-30% due to chemotherapy and the surgical removal of metastases and primary tumor. However, the most effective drugs are still the same as those employed over the last 20 years as front line neoadjuvant or adjuvant chemotherapy: Doxorubicin, Cisplatin, Methotrexate, Ifosfamide. No standard, second line therapy exists for those who relapse. At relapse, due to the lack of new non-cross-resistant drugs, surgery is still the main option when feasible. Other drugs have been employed in relapsed patients with poor results. This article reviews the state of the art of treatment for bone osteosarcoma in the pediatric age.

Abstract
BACKGROUND Approximately one-third of patients with osteosarcoma who have a complete response to their initial treatment can be expected to relapse. It is important to define what host, tumor, or treatment characteristics determine outcome after relapse. We present findings in 59 patients treated at our institution from 1974 to 1996 who have relapsed one or more times after their initial response. METHODS Host and tumor characteristics at diagnosis and relapse, therapeutic interventions and survival outcomes were determined from examination of medical records and a follow-up questionnaire. RESULTS Of the 59 patients, 37 initially presented with localized disease of the extremity, 11 with localized non-extremity disease, and 11 with metastatic disease. This report focuses on those with localized disease of the extremity. For these patients, median time from original diagnosis to first recurrence was 14 months. Median survival after first recurrence was 31 months. The median post initial relapse survival was the same for patients whose first relapse occurred before or after 14 months from original diagnosis. Seventeen of 29 patients with systemic metastasis at first recurrence had complete removal of their disease and had a median post-op survival of 2.5 years, while the remaining 12 patients with no surgery, had a median survival of 2 years. Of the 37 patients who presented with primary disease only in the extremities and relapsed: 31 died (2 more than 6 years from first recurrence) and 6 are alive from 6 to 24 years from first recurrence (5 without disease and 1 with disease). Three of the five disease-free survivors had three or more relapses. CONCLUSION With a long follow-up time, we found 15% of patients with relapsed osteosarcoma who originally presented with localized disease in the extremity are alive with no evidence of disease at 10 years from first recurrence (Kaplan-Meier estimate). Even patients with multiple relapses may have long-term disease-free survival after salvage therapy. Chemotherapy and time to first recurrence were unrelated to survival after relapse in this study. Complete surgical removal of metastatic disease may be important for long-term survival.

Abstract
Osteosarcoma, the most common type of primary malignant tumour that develops in bone, can be classified into several different sub-types. While the majority of osteosarcomas are highly malignant, there are some low-grade variants. Since the introduction of chemotherapy into the multi-modal treatment regimen of high-grade osteosarcoma, its prognosis has impressively improved, with long-term survival being achieved in two-thirds of all patients. This review summarises current chemotherapeutic treatment strategies in classical osteosarcoma and also addresses the indication for chemotherapy in more unusual types and variants. It emphasises the need for treatment in specialised centres and within prospective, multi-institutional trials, amongst which EURAMOS1 and EURO-B.O.S.S are currently active in many European countries.

Abstract
The aim of this study was to identify predictive factors of late relapse in nonmetastatic osteosarcoma patients treated at the Rizzoli Institute from 1983 to 1997. Clinical features of patients who had late (>4 y of follow-up) or earlier recurrence were compared. Late relapse was reported in 24 (3.7%) of the 648 patients who entered the studies. A surgical complete remission was achieved in 19 (79%) patients. The 5-year probability of postrelapse survival was 65% for the complete remission patients (48% in the entire group), which was significantly better than that of the patients (5-year postrelapse survival 20%) with an early relapse. Sex, site, and size of the tumor, histologic subtype, alkaline phosphatase and lactate dehydrogenase serum levels, type of surgery, and histologic response did not significantly differ between patients with late or early relapse. No clinical predictive factors of late relapse were identified and a prolonged follow-up is recommended for all patients.

Abstract
BACKGROUND The role of erbB tyrosine kinases, especially Her-2, in osteosarcoma has engendered intense debate. Some investigators identified an association between low-level Her-2 expression, compared to none, and poor patient outcome. Others questioned the importance of apparent cytoplasmic expression of Her-2, since membranous overexpression is associated with poor outcome in carcinomas. We previously demonstrated that primary osteosarcoma cells express cell-surface EGFR and Her-2, with the p80 isoform of Her-4 localized to the nucleus. We wished to determine if erbB kinases in osteosarcoma were phosphorylated, and if this was required for growth. PROCEDURES We cultured early passage osteosarcoma cell lines in the presence or absence of the pan-erbB inhibitor CI-1033 and examined the phosphorylation status of EGFR, Her-2, and Her-4 by immunohistochemistry, cell-based ELISA, flow cytometry and two dimensional Western blot. We also assessed the impact of CI-1033 upon osteosarcoma growth and survival in vitro. RESULTS EGFR, Her-2, and Her-4 were constitutively phosphorylated in early passage osteosarcoma cells cultured in vitro. CI-1033 abrogated erbB receptor phosphorylation and caused growth inhibition and apoptosis in a titratible fashion with concentrations of 1 muM or more. CONCLUSIONS EGFR, Her-2, and Her-4 are constitutively phosphorylated in early passage osteosarcoma cells in tissue culture, and erbB signaling provides essential growth and anti-apoptotic signals to osteosarcoma cells. This suggests that erbB overexpression is not required for erbB to promote malignancy, but rather that overexpression is one of several mechanisms that generate unregulated erbB signaling.

Abstract
Primary high-grade intramedullary osteosarcoma of the extremities is a clinically aggressive bone tumour. There is an ongoing effort to further improve efficacy of neo-adjuvant chemotherapy and reduce chemotoxicity by trying to identify osteosarcoma patients who are at risk of treatment failure as well as to identify those who can do with less chemotherapy. In only 5% of patients, first distant metastasis or local relapse occurs 5 years or more after initial treatment for osteosarcoma. Patients and physicians can therefore easily erroneously consider a patient with osteosarcoma cured if he or she is disease-free for more than 5 years following diagnosis and treatment. To investigate if these rare late relapsing patients are characterised by specific clinico-pathological features, we examined clinical and histological variables of late relapse (first local recurrence or metastasis 5 years or more after initial diagnosis) out of a total of 2,243 patients, with a special interest in the histological osteosarcoma subtype. In total, 33 patients had a documented relapse 5 years or more after diagnosis. Half of the patients had good response (>or=90% necrosis) to pre-operative chemotherapy and the other half a poor response (<90% necrosis) and late relapses seemed to be more frequently proportionately in those who had a good initial response to chemotherapy. The occurrence of late relapse did not appear to be associated with age or gender. Although not statistically significant, there was a trend for patients with a chondroblastic subtype of osteosarcoma, or a location in the tibia or fibula, to have a higher risk for late relapse.

Abstract
Although there has been considerable improvement in survival among children with osteosarcoma over the past 30 years, patients with metastatic disease fare very poorly. The best-case scenario for metastatic patients is a survival rate of 30% assuming complete resection of lung metastases without other disease. To achieve this optimal outcome, an aggressive surgical approach is recommended in which all metastatic disease is resected. This includes metastatic foci that are detected by imaging as well as those only identified by palpation at thoracotomy. Investigation into the biology of the metastatic process of osteosarcoma as well as in identification of molecular features that correlate with prognosis is very active and will likely yield important findings that will impact therapy in the future. An area of investigation that remains needed is the prospective evaluation of the surgical management of these patients with the goal of critically evaluating the impact of the various surgical strategies on patient outcome measures, such as disease-recurrence and survival.

Abstract
CD99 was recently reported to be under control of the osteoblast-specific transcription factor Cbfa1 (RUNX2) in osteoblasts, suggesting a role in the phato-physiology of these cells. No extensive information is available on the role(s) of this molecule in malignant phenotype, and osteosarcoma, in particular, has never been studied. We report that in 11 different cell lines and 17 clinical samples CD99 expression is either undetectable or very low. Being expressed in the normal counterpart, we tested the hypothesis that CD99 down-regulation may have a role in osteosarcoma development and progression. CD99-forced expression in two osteosarcoma cell lines significantly reduced resistance to anoikis, inhibited growth in anchorage independence as well as cell migration, and led to abrogation of tumorigenic and metastatic ability. Therefore, the molecule acts as a potent suppressor of malignancy in osteosarcoma. CD99 gene transfection induces caveolin-1 up-regulation and the two molecules were found to colocalize on the cell surface. Treatment with antisense oligonucleotides to caveolin-1 abrogates the effects of CD99 on migration. The findings point to an antioncogenic role for CD99 in osteosarcoma, likely through the regulation of caveolin-1 and inhibition of c-Src kinase activity.

Abstract
BACKGROUND Surgical resection of lung metastases is widely accepted in osteosarcoma patients. Few data exist on treatment of recurrent pulmonary metastases. The authors of the current study retrospectively analyzed patients with osteosarcoma who received surgery for recurrent lung metastases. METHODS From 1980 to 2001, 127 metastasectomies were performed on 94 patients. Criteria of eligibility were no metastases beyond the lung, no local recurrence, possibility of achieving complete resection of metastases without causing respiratory insufficiency, acceptable operative risk. Data were statistically elaborated with survival analysis according to Kaplan-Meier method of univariate analysis, life tables and Gehan statistic model, and multivariate analysis using Cox regression test. Results were considered in terms of time from first (DFI1) and second (DFI2) metastasectomy. RESULTS Of 94 patients operated upon twice, 59 (62.7%) died. Thirty-five (37.3%) are alive; 31 (32.9%) of these are continuously disease-free. The 3- and 5-year event-free actuarial survival curve from first metastasectomy was 45%, and 38%, respectively, whereas from the second metastasectomy, it was 33% and 32%, respectively. According to a Cox regression model, DFI1 has a risk of death of 0.974 times and DFI2 of 0.972 times for every additional month of survival. In multivariate analysis, Cox regression test showed the best predictive model of local recurrence and number of metastases (P = 0.0014). CONCLUSIONS The authors concluded that patients persistently free of the primary osteosarcoma who developed recurrent resectable metastatic disease of the lung should be considered for reoperation a second, third, or fourth time, as these patients had similar DFI curves after five-years.

Abstract
BACKGROUND Overall survival after recurrence of osteosarcoma (OS) is < 30%. The authors reported their experience treating recurrent OS at the time of first recurrence (R1). METHODS Patients with high-grade OS who achieved complete disease remission (CR) after primary surgery and chemotherapy, and patients who were treated at R1 at Memorial Sloan-Kettering Cancer Center (New York, NY) after 1990 were analyzed by retrospective chart review. RESULTS For 43 eligible patients, the median time to R1 from initial diagnosis was 21.7 months (range, 4.6-135.7 mos). The lungs were the most common sites of disease recurrence (n = 33 of 43). With a median follow-up of 15.2 months (range, 0.7-158.3 mos) after R1, 15 of 43 (35%) patients were alive. Four of 43 patients were treated with surgery alone (3 patients were alive and 1 had died of progressive disease at the time of last follow-up). Due to unresectable disease, eight patients received only chemotherapy, none of whom survived. For patients with disease recurrence treated with chemotherapy and surgery (n = 31), 22 patients achieved a second CR (CR2). Nine patients were alive and in disease remission (29%) at the time of last follow-up. Twenty-three patients received ifosfamide as part of their retrieval regimen. Of the 18 who achieved a CR2, 8 experienced disease recurrence, 7 remain alive in CR2, and 3 died due to toxicity. Eight patients did not receive ifosfamide. Of these, 4 achieved a CR2 but 3 subsequently experienced disease recurrence. CONCLUSIONS At R1, 22 of 31 patients achieved a CR2 with aggressive surgery and chemotherapy. The majority of these patients subsequently developed a disease recurrence. Patients appeared to benefit from the addition of ifosfamide to their retrieval regimens. In the end, the role of chemotherapy in recurrent OS continues to remain undefined.
