Abstract
BACKGROUND Osteosarcoma is the most prevalent primary malignant bone tumor. The primary treatment for osteosarcoma is a combination of chemotherapy and surgery. However, there has been no recent progress in the role of chemotherapy in improving the long-term survival of osteosarcoma patients. This study aims to analyze the factors that affect chemotherapy in patients with osteosarcoma and explore the challenges and survival benefits of chemotherapy. METHODS Patient data were downloaded from The Surveillance, Epidemiology, and End Results database. Univariable and multivariable logistic regressions were used to analyze the factors affecting patients receiving chemotherapy. Kaplan-Meier (K-M) curve was used to analyze the survival benefit of chemotherapy in patients with osteosarcoma. Finally, we used annual percentage change (APC) to evaluate the annual changes in chemotherapy treatment rates and trends in 5-year survival rates in osteosarcoma patients. RESULTS A total of 2157 osteosarcoma patients were included, of which 1887 patients received chemotherapy. Factors affecting patients receiving chemotherapy included age, primary tumor site, tumor size, N stage, M stage, and surgery. The K-M curve showed that older patients could benefit significantly from chemotherapy. The APC results showed no significant change in the chemotherapy treatment rate and 5-year overall survival rate of osteosarcoma patients. CONCLUSION Chemotherapy is an irreplaceable treatment for patients with osteosarcoma. However, in recent years, there has been no significant progress in chemotherapy for osteosarcoma, and the long-term survival of patients has not improved significantly. New chemotherapeutic drugs or drug delivery systems are urgently needed to improve the prognosis of patients with osteosarcoma.

Abstract
Osteosarcoma is the most common primary bone tumor and usually involves the long bones. Osteosarcoma of the skull, on the other hand, is relatively rare. Here, we present a 29-year-old man with a growing mass in the skull he first noticed after a fall while skateboarding. The initial clinical diagnosis was hematoma. While undergoing an evacuation surgery for a hematoma, a suspicious mass was detected which was biopsied. Histopathological evaluation showed high-grade osteosarcoma. The patient was referred to our hospital where he underwent definitive resection followed by adjuvant chemotherapy. His course was complicated by wound infection. Even though osteosarcoma of the skull is a rare finding, it should be suspected in a patient with a skull mass, and the history of prior head trauma does not exclude the diagnosis.

Abstract
Objective The objective of this study is to describe the clinical presentation, tumor characteristics, natural history, and treatment patterns of sinonasal osteosarcoma. Methods Fourteen patients who had been treated for osteosarcoma of the nasal cavity and paranasal sinuses at a tertiary care center were reviewed. In addition, a systematic review of the literature for osteosarcoma of the sinonasal cavity was performed. Results In a systematic review, including 14 patients from the authors' institution, 53 total studies including 88 patients were assessed. Median follow-up was 18 months (interquartile range: 8-39 months). The most common presenting symptoms were facial mass or swelling (34%), and nasal obstruction (30%). The most common paranasal sinus involved by tumor was the maxillary sinus (64%), followed by the ethmoid sinuses (52%). The orbit (33%), dura (13%) and infratemporal fossa (10%) were the most common sites of local invasion. The majority of patients underwent surgery followed by adjuvant therapy (52.4%). Increasing age was associated with decreased overall survival rate (unit risk ratio [95% confidence interval (CI)] = 1.02 [1.003-1.043]; p = 0.0216) and T4 disease was associated with decreased disease-specific survival rate (hazard ratio [HR] = 2.87; p = 0.0495). The 2- and 5-year overall survival rates were 68 and 40%, respectively, while 2- and 5-year disease-specific survival rates were 71% and 44%, respectively. Conclusion Sinonasal osteosarcomas are uncommon tumors and can pose a significant therapeutic challenge. Increasing age and T4 disease are associated with worse prognosis. This disease usually warrants consultation by a multidisciplinary team and consideration of multimodality therapy.

Abstract
Primary osteosarcoma of sphenoid and ethmoid sinus present as a challenge in head neck cancer. A 17 year female presented with left sided hemifacial pain, headache with nasal discharge. Clinico-radiological finding showed mass in sphenoethmoid recess spreading to adjacent structures. Endoscopic resection was done. Histopathological diagnosis was osteosarcoma of sphenoid and ethmoid sinus. Adjuvant chemotherapy administered. Osteosarcomas of sphenoid and ethmoid sinus are aggressive tumors with variable clinical features warranting high clinical suspicion.

Abstract
RATIONALE Primary osteosarcomas of the skull and skull base are rare, comprising <2% of all skull tumors. Primary osteosarcomas of the skull are aggressive neoplasms composed of spindle cells producing osteoid which have poor outcome. PATIENT CONCERNS A 33-year-old woman was admitted to our hospital with a major complaint of a growing mass on her left frontal region of the skull for 10 months. Prior to the accurate diagnosis, the mass on her skull was considered to be eosinophilic granuloma. DIAGNOSES Computerized tomogram (CT) scan of skull revealed a lytic lesion causing destruction of left frontal bone with surrounding soft tissue mass. The histological examination of the lesion showed typical features of osteosarcoma. INTERVENTIONS The patient received 3 surgeries and adjuvant chemotherapy and radiotherapy for the frontal bone lesion. OUTCOMES At the last follow-up, after 4 years, the patient was free of disease both clinically and on imaging by magnetic resonance imaging (MRI) scan after 4 years. LESSONS Because osteosarcoma of skull is a rare disease, the early recognition and correct diagnosis are very important for a better prognosis. It is therefore imperative that clinicians recognize osteosarcoma early to make an accurate diagnosis and complete surgical resection followed by combined chemo-radiation is proved to be one of the most optimal treatment regimens.

Abstract
High-grade craniofacial osteosarcoma (CFOS) is an aggressive malignancy with a poor prognosis. Our goals were to evaluate treatment outcomes in those treated at a single referral institution over 35 years and to compare our results to the available literature. A retrospective analysis of all 42 patients treated between 1980 and 2015 at Oslo University Hospital, Norway, identified in a prospectively collected database, was conducted. Mean follow-up was 79.6 months. Overall survival at 2 and 5 years was 70.5 and 44.7%, respectively. The corresponding disease-specific survival rates were 73.0 and 49.8%. Treatment was surgery only in eight cases. Additional therapy was administered in 34 patients: chemotherapy in nine, radiotherapy in seven, and a combination of these in 18 cases. Stratified analysis by resection margins demonstrated significantly better survival at 2 and 5 years after radical surgical treatment. Neoadjuvant chemotherapy and subsequent adequate surgery resulted in better survival than surgery alone. Half of the patients either had a primary or familial cancer predisposition. This is the largest single-center study conducted on high-grade CFOS to date. Our experience indicates that neoadjuvant chemotherapy with complete surgical resection significantly improved survival, compared to surgery alone.

Abstract
BACKGROUND Osteosarcoma is the second most common primary tumor of the skeletal system and the most common primary bone tumor. Usually occurring at the metaphysis of long bones, osteosarcomas are highly aggressive lesions that comprise osteoid-producing spindle cells. Craniofacial osteosarcomas comprise <8% and are believed to be less aggressive and lower grade. Primary osteosarcomas of the skull and skull base comprise <2% of all skull tumors. Osteosarcomas originating from the clivus are rare. We present a case of a primar, high-grade clival osteosarcoma. CASE DESCRIPTION A 29-year-old man presented to our institution with a progressively worsening right frontal headache for 3 weeks. There were no sensory or cranial nerve deficits. Computed tomography revealed a destructive mass involving the clivus with extension into the left sphenoid sinus. Magnetic resonance imaging revealed a homogenously enhancing lesion measuring 2.7 × 2.5 × 3.2 cm. The patient underwent endonasal transphenoidal surgery for gross total resection. The histopathologic analysis revealed proliferation of malignant-appearing spindled and epithelioid cells with associated osteoclast-like giant cells and a small area of osteoid production. The analysis was consistent with high-grade osteosarcoma. The patient did well and was discharged on postoperative day 2. He was referred for adjuvant radiation therapy and chemotherapy. Two-year follow-up showed postoperative changes and clival expansion caused by packing material. CONCLUSIONS Osteosarcoma is a highly malignant neoplasm. These lesions are usually found in the extremities; however, they may rarely present in the craniofacial region. Clival osteosarcomas are relatively infrequent. We present a case of a primary clival osteosarcoma with high-grade pathology.

Abstract
Parosteal osteosarcoma (OS) of the jaw is a rare type of OS with peculiar clinical radiographic and microscopic features. The aim of this article was to report and discuss a case of high-grade parosteal OS in the mandible of a 35-year-old woman. The patient reported sensing mild pain and swelling in the retro molar area on the left side of the mouth for a period of 4 years, despite continuous dental treatment. The radiographic evaluation showed a mixed radiopaque/radiolucent lesion in the body of the left side of the mandible. Destruction of the mandibular cortex in that area was also observed. After the initial histological study, the patient underwent partial hemi-mandibulectomy. Microscopic findings showed a tumor exhibiting spindle cells with nuclear hyperchromasia, moderate pleomorphism, and irregular osteoid formation, with chondroid differentiation noted with tumor-free margins. The immunohistochemical analysis showed the expression of negativity to p53, human epidermal growth factor receptor 2/neu, and positivity to S-100. The diagnosis was high-grade parosteal OS of the jaw. The 4 years clinical and imaging postoperative follow-up showed no evidence of recurrence. The literature on this unusual pathologic entity reviewed and diagnostic challenges described.

Abstract
Background FNAC of intraosseous jaw lesions has not been widely utilized for diagnosis due to rarity and diversity of these lesions, limited experience and lack of well established cytological features. Aim of the study was to determine the role of FNAC in the diagnosis of intraosseous jaw swellings.
Material and Methods 42 patients underwent FNAC over a period of 7 years (2007-2013), of which 37 (88.1%) aspirates were diagnostic. Histopathology correlation was available in 33 cases and diagnostic accuracy of FNAC was calculated. Results Lesions were categorized into inflammatory 3, cysts/hamartomas 15 and neoplasms 19. Mandibular and maxillary involvement was seen in 21 and 16 patients respectively. Of these, benign cysts and malignant lesions were commonest, accounting for 27% lesions (10 cases) each. One case of cystic ameloblastoma was misdiagnosed as odontogenic cyst on cytology. Overall, sensitivity and specificity of FNAC were 94.7% and 100% respectively with a diagnostic accuracy of 97.3%. Definitive categorization of giant cell lesions, fibro-osseous lesions, odontogenic tumors and cystic lesions was not feasible on FNAC. Conclusions FNAC is a simple, safe and minimally invasive first line investigation which can render an accurate preoperative diagnosis of intraosseous jaw lesions, especially the malignant ones in the light of clinic-radiological correlation. Key words:
Jaw swellings, intraosseous, FNAC.

Abstract
Cranial osteosarcoma is very rare in children, rendering the development of optimal treatment algorithms challenging. The authors present 3 cases of pediatric cranial osteosarcoma: a primary calvarial tumor, a cranial metastasis, and a primary osteosarcoma of the cranial base. A review of the literature demonstrates significant variation in the management of cranial osteosarcomas and the outcome for patients with these tumors. This series and literature review is presented to improve the understanding of pediatric cranial osteosarcoma and to reinforce the importance of maximal resection in optimizing outcome.

Abstract
Osteosarcoma of the cranio-facial structures and skull is rare. In children, only 5.6% of cases are localized in these areas. It is claimed that the mean age at presentation is at least 10-15 years higher than for osteosarcomas in other parts of the body. However these reports are based on data from single institutions or compiled from several registries. It is further claimed that tumours in the mandible and maxilla are less malignant, as based on observations of a better prognosis and lower incidence of metastatic spread as compared with osteosarcomas arising elsewhere. We report all histologically proven cranio-facial osteosarcomas in The Netherlands occurring over a 20-year period, based on the national registration covering all Dutch pathology laboratories (PALGA). The age-corrected incidence of primary osteosarcoma ranged from 0.33 to 0.41 per million across the age ranges. The mandible was the most frequent site of involvement. Only 61% had a high malignant histological grading. Our data indicate that the age-corrected incidence of primary osteosarcomas is similar across all age ranges. In respect to histology, a lower grade of malignancy is more frequent. Maxillary lesions significantly more often have a lower histological grade of malignancy.

Abstract
AIMS To analyse a series of cases of osteosarcoma of the jaw. METHODS AND RESULTS The study included 74 cases of osteosarcoma of the jaw. Their clinical, radiographic and histopathological features were analysed, and their frequency with respect to aggressive and malignant pathologies of the jaw was determined. Survival was assessed in 17 cases with available follow-up. Osteosarcoma of the jaw accounted for 10% of primary malignant and aggressive tumours of the jaw, and for 8% of all malignant lesions of the jaw, including metastatic and lymphoproliferative tumours. The mean age was 43 ± 18 years. Radiographic features varied greatly and were non-specific, with a predominance of mixed images. The dominant histological pattern was osteoblastic (48.4%), followed by chondroblastic (37.1%). The survival rate at 5 years was 68%. Females and patients with a predominantly chondroblastic pattern had lower survival rates. CONCLUSIONS Osteosarcoma of the jaw was the most frequent primary malignant tumour of the jaw. Female gender and a predominantly chondroblastic pattern may be associated with a worse prognosis.

Purpose. It is assumed that osteosarcomas of the jaws mainly occur at older ages, whereas the most prominent sites, that is, the long bones, are more affected at ages <20. Jaw-localized tumors are less malignant and have lower metastatic spread rates. Patients and Methods. This study analyses the nationwide data of the Dutch Cancer Registry on osteosarcoma during the period from 1991 to 2010. Age-corrected incidence rates were calculated. Results. In 949, 38 patients had tumors in the maxilla and in 58 in the mandible. Median age for maxilla, mandible, and other localizations was 45.5, 49, and 23 years, respectively. Age-corrected incidence for osteosarcomas increased after a steep decline for the age cohorts from 20 to 60 years to nearly the same level as the younger patients. The incidence for maxillary lesions showed a steady increase from 0.46 to 1.60 per million over all age ranges; the highest incidence for mandibular lesions was found in the age cohort from 60 to 79 years. In respect to histology, no shifts for age were found, except for Paget's disease-related osteosarcoma. In older patients, chemotherapy was omitted more often. Overall survival was similar for all age groups, except for extragnatic tumor patients in the age range of 60-79 years. Conclusions. Osteosarcomas have comparable incidences below the age of 20 as compared with ages >60 years. Poorer outcome in older people is likely due to refraining from chemotherapy.

Abstract
An aggressive and fatal case of osteosarcoma of the mandible in a 19-year-old female is reported. Six weeks after the clinical appearance of the swelling, the patient died. This paper is unique in that the age of occurrence and the biologic behavior of the tumor were not consistent with the reported literature. The case report is followed by a brief review of osteosarcoma of the jaw with a note on its clinical presentation, diverse radiologic appearance, varied histopathologic picture, and prognosis.

Abstract
Primary osteosarcoma of skull base is extremely rare. We present a case of primary osteosarcoma arising in greater wing of sphenoid in a child. Our patient had an incomplete excision after which he received adjuvant chemotherapy and radiotherapy. There was good response to adjuvant chemoradiotherapy and the patient is disease free at a follow-up of 18 months. Treatment of skull base osteosarcomas is difficult, as complete excision is often not possible. To the best of our knowledge, this is the first case of sphenoid wing osteosarcoma in childhood to be reported in literature.

Abstract
BACKGROUND AND OBJECTIVES This study analyzed maxillary osteosarcoma in a mestizo population, with particular emphasis on the type of treatment and disease-free and overall survival. METHODS This is a retrospective study including all mestizo patients with osteosarcoma of the maxilla seen in a single cancer institution in Mexico during a 20-year period. RESULTS There were 21 patients. Age ranged from 16 to 76 years (mean, 37.5 y). Mean evolution time to diagnosis was 13 months, with a mean tumor size of 7 × 6 cm2. Surgery was the initial treatment in 19 patients, 17 of whom received adjuvant treatment. Disease-free survival according to surgical margin and overall survival were not statistically significant. Disease-free survival was 29% at 5 years, and overall survival was 50% and 25% at 5 and 10 years, respectively. CONCLUSIONS Osteosarcomas of the maxilla are infrequent lesions that merit early diagnosis and proper treatment because of their rapid evolution. Treatment is currently based on a well-planned surgery with free surgical margins plus adjuvant radiotherapy and/or chemotherapy.

Abstract
AIMS AND BACKGROUND Ezrin is a membrane-cytoskeleton linker protein involved in regulation of the growth and metastatic behavior of cancer cells. Metastatic tumor antigen (MTA) is a potential metastasis-associated protein. The objective of this study was to evaluate the expression of ezrin and MTA and their correlation with clinicopathological features in osteosarcomas of the jaw. METHODS We analyzed ezrin and MTA protein levels by immunohistochemistry in 31 osteosarcomas of the jaw. RESULTS The mean age at diagnosis was 39 years and half of the patients were male. The mandible (n = 19) was more frequently involved than the maxilla (n = 12). The predominant histological type was chondroblastic (58.1%) and 24 patients (77.4%) were classified as having a high grade of malignancy. Immunoreactivity for ezrin was identified in 6 of 31 cases (19.4%), while 77.4% displayed expression of MTA. All ezrin-positive patients had high-grade tumors. The high-grade tumors (n = 24) had a higher rate of MTA expression (42.9% vs 87.5%). Expression of ezrin and MTA was not significantly different according to age, sex, tumor site, histological type, and tumor ploidy. Follow-up information was available for 13 patients, with a mean follow-up time of 26.7 months (range, 6-48 months). At the time of last follow-up, 5 (38.5%) patients had died of disease and 8 patients (61.5%) were alive with no evidence of disease. Expression of ezrin and MTA was not significantly different according to the follow-up data. CONCLUSIONS In our study, high-grade tumors had a higher rate of ezrin and MTA expression. This expression pattern indicates that ezrin and MTA positivity can be additional prognostic markers in osteosarcoma of the jaw.

Abstract
This study was done with an aim to assess the reliability and diagnostic accuracy of fine needle aspiration biopsy of intraosseous jaw lesions. Of the 42 cases, adequate material for cytologic evaluation was obtained in 35 cases. Malignant cells were found in 9 of 35 cases. FNAB diagnosis was confirmed by histopathology in all 9 of these specimens (100% accuracy). The FNAB diagnosis of benign lesions was confirmed in 19 of 26 cases (73% accuracy). The most common benign lesions were odontogenic cysts, followed by fibro-osseous and giant cell lesions. Incorrect diagnosis was related to lack of architectural context of the FNAB material, inadequate quantity of the aspirate and sampling of a non-representative part of a large lesion. Thus FNAB is a useful, simple, fairly reliable and outpatient procedure for diagnosis of intra-osseous jaw lesions, especially to distinguish between malignant and benign jaw lesions.

Abstract
The aim of this retrospective analysis was to evaluate patient and tumor characteristics and treatment results and prognostic factors for patients with craniofacial osteosarcoma (CFOS). The COSS database was searched for patients with previously untreated, histologically confirmed craniofacial osteosarcoma with at least one follow-up examination. In a 28-year period extending from 1977 to 2004, 49 eligible patients were identified and their charts retrospectively analysed. The median age at diagnosis was 19.7 years (range: 4.6-57.2) with no gender predilection. Thirteen CFOS were second or even third primary malignancies. The jaws were the primary site in 27 patients (55% - mandible 15 (31%), maxilla 12 (24%)), while extragnathic bones were involved in 22 (45%). All 49 patients underwent surgery; in 37 (76%) combined with chemotherapy, in seven (14%) with chemotherapy and radiotherapy. Twenty-one patients (43%) received preoperative chemotherapy and the other 28 (57%) had primary surgery. A complete surgical remission was achieved in 32 patients, of whom 24 remained in local control. Actuarial five-year overall and event-free survival rates were 74% and 44%, respectively. Extragnathic site (p<.001) and documented postsurgical rest of the primary tumor (p<.001) were associated with inferior overall survival probabilities. All 24 patients who achieved and maintained local surgical control survived disease-free. Multidisciplinary treatment of CFOS within a multicenter setting resulted in long-term survival in well over two thirds of affected patients. Extragnathic sites and failure to achieve and maintain local surgical control emerged as strong negative prognostic factors.

Abstract
BACKGROUND Osteosarcoma of the jaw (JOS) constituting 5% to 13% of all osteosarcoma is a locally aggressive malignant mesenchymal tumor with high tendency to local recurrence and the ability to produce tumor osteoid. Compared to osteosarcoma of the remaining skeleton (SOS) JOS metastasizes relatively rarely and relatively late. It differs significantly from SOS in its biological behaviour. CASE REPORT The presented case deals with a 60-year-old male patient suffering from a newly occurred polypous mucosal tumor of the right-sided maxillary alveolar ridge bioptically diagnosed as a granulation tissue polyp first. After transmaxillary resection of the tumor and consultation of a bone tumor reference center the final diagnosis of a high-grade chondroblastic osteosarcoma could be made. The recommended radical resection of the tumor was declined by the patient because of the expected cosmetic consequences. After surgical reduction of the rapidly growing sarcoma chemotherapy according to the COOS/EURO-B.O.S.S. protocol was initiated at a stage when computed tomography showed diffuse metastatic disease to the lungs. Chemotherapy could delay the progress of the disease only temporarily. The patient died from respiratory insufficiency. CONCLUSION In JOS radical surgical resection is the therapy of first choice. For substantiation of the diagnosis and central registration of the cases a bone tumor reference center should be contacted.

Abstract
Osteosarcoma is an infrequent, locally aggressive neoplasm in the head and neck region. To date, surgery is the mainstay of treatment. However, patients with mandibular osteosarcomas usually have a locally advanced disease at diagnosis and therefore represent a therapeutic challenge because surgical margins are difficult to obtain due to aesthetic and functional concerns. To evaluate possible prognostic factors implicated in recurrence, persistence or relapse in osteosarcoma of the mandible, with special reference to the soft tissue and bone surgical margins. A series of 20 patients with mandibular osteosarcomas treated at the Instituto Nacional de Cancerología (México) from 1985 to 1999 are reviewed. There were 14 female and 6 male patients. Twelve cases were treated with surgery alone, 3 patients with surgery and adjuvant radiotherapy, 1 had neoadjuvant chemotherapy followed by surgery, 1 had neoadjuvant chemotherapy, surgery and postoperative radiotherapy, 1 with surgery and adjuvant chemotherapy, 1 with surgery followed by adjuvant chemotherapy and radiotherapy and one patient rejected treatment. Between 1985 and 1992 these neoplasms were treated by means of total mandibulectomy, independently of tumor size, but between 1993 and 1999 the policy was to practice smaller resections but long enough to obtain macroscopic surgical free margins. In the first period the relationship between mandibular size resection and tumor size was 1.9, meanwhile in the second period the relation was 1.5. There was not significant difference between both periods in terms of tumor size (6.0 cm vs. 6.02 cm at the time of surgery) nor in local control and survival. Soft tissue involvement as reported by histological study was strongly associated with recurrence (p = 0.0024). Overall 5-year survival was 20%. A policy of total mandibulectomy is not associated with a better local control or survival. Extent of resection must be tailored with tumor size. Extent of margins in soft tissue is the limiting factor for local control.

Abstract
Two cases of osteosarcoma of the jaws in children are reported. One patient was a 13-year-old girl whose first symptoms included nasal and maxillary sinus congestion, followed by epistaxis. She was found to have chondroblastic osteosarcoma extending through the left maxillary alveolar process and sinus. Following surgery and chemotherapy, the patient has been free of disease for 7 years. The second patient, an 8-year-old boy, was diagnosed with juxtacortical (parosteal) osteosarcoma of the mandible, which is a less aggressive variant of the neoplasm. It is believed that this is the youngest patient reported to date with juxtacortical osteosarcoma of the jaws. He was treated by block resection of the right side of the mandible and is free of disease 3(1/2) years later.

Abstract
Osteosarcomas are highly malignant neoplasms of bone that are challenging to diagnose. These neoplasms often show atypical behavior. In the initial phase they may present as nondescript bony swellings with an indolent growth rate, only to become overtly aggressive and malignant towards the later phase of the disease. Similarly, the histological growth pattern of this neoplasm can be quite diverse, presenting with areas that mimic benign myofibroblastic tumors, giant cell granulomatous conditions and partial encapsulation. The final diagnosis of an osteosarcoma is often reached after thorough sampling and examination of multiple biopsy specimens. All these clinical features and histological diagnostic difficulties were encountered in a case of osteosarcoma affecting the right mandible of a 62-year-old Chinese woman described here. The diagnostic lessons accrued from this case are discussed.

Abstract
PURPOSE We describe the occurrence of maxillary and orbital osteogenic sarcoma in a child after treatment of contralateral orbital rhabdomyosarcoma with external beam radiation and chemotherapy. DESIGN Interventional case report. INTERVENTION Treatment of a maxillary and orbital rhabdomyosarcoma with surgical resection, systemic chemotherapy, and local radiation. MAIN OUTCOME MEASURES Occurrence and histology of secondary malignancy after orbital radiation. RESULTS An eleven year-old male presented for evaluation of left facial swelling, occurring ten years after successful treatment of a right orbital embryonal rhabdomyosarcoma with chemotherapy and 5040 cGY of external beam radiation. Computerized tomography demonstrated a mass involving the left maxillary sinus and orbital floor. Biopsy demonstrated osteogenic sarcoma. Despite attempted total excision with radical maxillectomy, resection margins were found to have microscopic extension of the tumor. Postoperatively he was treated with systemic chemotherapy and local radiation. Eight months postoperatively he remains alive despite local progression. CONCLUSIONS Osteogenic sarcoma can occur as a secondary malignancy years after the successful treatment of orbital rhabdomyosarcoma with external beam radiation and chemotherapy. After orbital radiation, subjects should undergo routine lifelong examinations.

Abstract
The aim of this study was to analyze the clinicopathological features and immunohistochemical expression of p53, MDM2, CDK4, PCNA and Ki67 proteins in 25 head and neck osteosarcomas registered in a single institution. The mean age of the patients was 29 years and the most common site was the mandible (60%). The predominant histological type was the chondroblastic (72%) and 52% of the cases were classified as intermediate-grade of malignancy. The immunohistochemical analysis displayed positivity in 52% of the cases for p53, 24% for MDM2, 84% for CDK4, 92% for PCNA and 88% for Ki-67. The majority of cases were treated with surgery alone or associated with chemotherapy. Five patients developed local recurrences, four had distant metastasis and six had persistent disease after initial treatment. The overall 5-year and 10-year survival rates were 59% and 49%, respectively, and the most important prognostic factors were prior history of radiation exposure and osteoblastic histological type.

Abstract
A 20-year-old male presented with an osteosarcoma in the right parieto-occipital bone occurring as a painless occipital lump which had rapidly enlarged in the 6 months prior to admission. The neuroimaging appearance resembled intraosseous meningioma. Gross total resection of the tumor was achieved. The final histological diagnosis was osteosarcoma. Osteosarcomas of craniofacial region have a better prognosis than those of the skeletal bones, and distant metastasis is rare. Local recurrence is the most significant factor contributing to poor outcome. Complete excision with negative margins is the key to a better outcome. Adjuvant therapy may be an option in cases of incomplete excision. Advances in target chemotherapy may diminish the significant morbidity associated with these lesions.

Abstract
BACKGROUND The current study reviews the authors' recent institutional experience in the treatment of osteosarcoma of the head and neck (OSHN). METHODS The clinical records of 44 patients who were treated between 1981 and 1998 for OSHN were reviewed retrospectively. Archived histologic material was reviewed and data were analyzed to identify factors predictive of disease control and survival. Outcomes were compared with a previously reported historic cohort treated at the study institution. RESULTS Patients ranged in age from 6 to 64 years (median, 31 years). The mandible was the primary site in 18 patients (41%), the maxilla in 20 patients (45%), and the skull in 6 patients (14%). Surgery was employed in all 44 patients, neoadjuvant chemotherapy was administered in 30 patients (68%), and postoperative radiation therapy was given to 7 patients (16%). The surgical excision margins were positive in 13 patients (30%). High-grade lesions were reported in 50% patients and low-grade lesions were noted in 18% of patients (grade was not assessable in 32%). Histologic response was "unfavorable" in 22 of 30 patients (73%) who were treated with neoadjuvant chemotherapy. The 3-year overall, disease-specific, and recurrence-free survival rates were approximately 81%, 81%, and 73%, respectively (median follow-up of 41 months). Positive surgical margins were found to be the only significant predictor of worse disease-specific survival. Compared with the historical cohort, the current experience demonstrated an obvious improvement in the 5-year local control (35% vs. 78%), distant metastases (37% vs. 13%), and overall survival (23% vs. 70%). CONCLUSIONS Negative surgical margins were found to be the only significant predictor of overall and disease-specific survival. The results of the current study represent a considerable improvement over the authors' previously published experience and compare favorably with the results reported in the literature.

Abstract
Odontogenic cysts that can be problematic because of recurrence and/or aggressive growth include odontogenic keratocyst (OKC), calcifying odontogenic cyst, and the recently described glandular odontogenic cyst. The OKC has significant growth capacity and recurrence potential and is occasionally indicative of the nevoid basal cell carcinoma syndrome. There is also an orthokeratinized variant, the orthokeratinized odontogenic cyst, which is less aggressive and is not syndrome associated. Ghost cell keratinization, which typifies the calcifying odontogenic cyst, can be seen in solid lesions that have now been designated odontogenic ghost cell tumor. The glandular odontogenic cyst contains mucous cells and ductlike structures that may mimic central mucoepidermoid carcinoma. Several odontogenic tumors may provide diagnostic challenges, particularly the cystic ameloblastoma. Identification of this frequently underdiagnosed cystic tumor often comes after one or more recurrences and a destructive course. Other difficult lesions include malignant ameloblastomas, calcifying epithelial odontogenic tumor, squamous odontogenic tumor, and clear-cell odontogenic tumor. Histologic identification of myxofibrous lesions of the jaws (odontogenic myxoma, odontogenic fibroma, desmoplastic fibroma) is necessary to avoid the diagnostic pitfall of overdiagnosis of similar-appearing follicular sacs and dental pulps. Fibroosseous lesions of the jaws show considerable microscopic overlap and include fibrous dysplasia, ossifying fibroma, periapical cementoosseous dysplasia, and low-grade chronic osteomyelitis. The term fibrous dysplasia is probably overused in general practice and should be reserved for the rare lesion that presents as a large, expansile, diffuse opacity of children and young adults. The need to use clinicopathologic correlation in assessing these lesions is of particular importance. Central giant cell granuloma is a relatively common jaw lesion of young adults that has an unpredictable behavior. Microscopic diagnosis is relatively straightforward; however, this lesion continues to be somewhat controversial because of its disputed classification (reactive versus neoplastic) and because of its management (surgical versus. medical). Its relationship to giant cell tumor of long bone remains undetermined.

Abstract
Overexpression and amplification of several genes (MDM2, CDK4 and SAS) located on chromosome 12q13-15 have been noted to occur in various human sarcomas. As a result, two major growth regulation pathways may be inhibited. MDM2 may down regulate the p53-mediated growth control and CDK4 may affect pRB-mediated events. To determine the frequency of alterations in these genes and their correlation with clinicopathologic features, we analyzed the MDM2 and CDK4 protein levels by immunohistochemistry and assessed MDM2, CDK4 and SAS amplification by real-time PCR in nine osteosarcomas of the jaws. Positive staining for CDK4 and MDM2 was observed in eight cases (88.8%) and five cases (55.5%), respectively. Intense CDK4 staining was noted in four cases (two high grade, one intermediate grade and one low grade). Intense MDM2 staining was observed in the same four previous cases, as well as, one additional high-grade tumor. Individual DNA amplification for CDK4, MDM2 and SAS was observed in six cases for each gene. Co-amplification was observed in five cases that showed CDK4 and MDM2 concomitant amplification and four cases that displayed amplification for all of the genes. In addition, among the five cases that presented CDK4 and MDM2 amplification, strong overexpression of CDK4 and MDM2 was observed in three and in four cases, respectively (three high grade and one intermediate grade). These results suggest that 12q13-15 genes are involved in neoplastic disease and concurrent amplification and overexpression of these genes might help to define high-grade tumors.

Abstract
OBJECTIVE The purpose of this article is to present 14 cases of osteosarcoma of the jaw treated at our medical center from 1989 to 1998. These cases are discussed in the light of a comprehensive review of 774 cases reported in the English literature over the past 3 decades. Differences between osteosarcoma of the jaws and osteosarcoma of the long bones are examined. SUBJECTS AND METHODS The patients ranged in age from 8 to 78 years, the mean age being 33 years. Each patient had a histopathologically established diagnosis of osteosarcoma of the jaw. Records were reviewed for epidemiologic data, treatment modalities, and survival. RESULTS Of the 14 patients, 6 (42%) had tumors in the mandible and 8 (58%) had tumors in the maxilla. Of the mandibular tumors, 5 occurred in the body of the mandible; all maxillary tumors originated in the alveolar ridge and involved the maxillary sinus. The chief complaint was an intraoral or extraoral painless swelling. Histopathologic types included chondroblastic, osteoblastic, fibroblastic, and malignant fibrous histiocytoma-like. Pathologic grade was determined to be high (3 or 4) in 13 cases and low (1) in only 1 mandibular case. All patients underwent surgical resection and immediate reconstruction. Adjuvant therapy included postoperative radiation (5 patients), postoperative chemotherapy (2 patients), and preoperative chemotherapy and postoperative radiation (1 patient). CONCLUSIONS The results of the present study support the literature indicating that osteosarcoma of the jaw differs from osteosarcoma of the long bones in its biological behavior even though they have the same histologic appearance. Because of differences in tumor characteristics, the introduction of chemotherapy did not dramatically alter the prognosis of osteosarcoma of the jaw. Early diagnosis and radical surgery are the keys to high survival rates.

Abstract
Osteosarcoma of the cranial facial region is uncommon and only rarely involves the ethmoid or sphenoid bones. The authors report on an unusual case of a 17-year-old male presenting with chondroblastic osteosarcoma of the maxillary, ethmoid, and sphenoid sinuses who remains well and disease-free at 46 months. He was treated with anterior craniofacial resection followed by postoperative radiotherapy to the sight of the primary tumor. He did not receive chemotherapy because of emerging hepatitis-B infection and vasculitis. The literature on extragnathic craniofacial osteosarcomas is reviewed with particular emphasis on treatment options of this rare tumor.

Abstract
A 28-year-old male presented with a primary osteosarcoma of the sphenoid bone with extensive periosteal extension manifesting as severe headache and right exophthalmos. Computed tomography (CT) and magnetic resonance imaging revealed an anterior middle cranial fossa tumor extending into both the orbit and the extracranial space. However, roentgenography and CT with bone windows showed no marked osteolytic changes of the sphenoid bone. Total removal of the tumor was performed via the orbitozygomatic approach. Surgery revealed that the tumor had extended periosteally without macroscopic bone destruction, but no obvious abnormalities of the skull. The histological diagnosis was osteosarcoma. The patient was treated with chemotherapy and radiation therapy, but died of tumor recurrence 10 months after the surgery.

Abstract
Head and neck sarcomas are very rare diseases. The aim of this study was to assess the prevalence and presentation of hard tissue sarcomas in the head and neck and jaws. A search of the British Columbia Tumor Registry identified 34 craniofacial hard tissue sarcomas (11 chondrosarcomas, 23 osteosarcomas) over a period of 29 years. A male predominance (1.8:1) and a mean age of 40.4 years at diagnosis were seen. Of the 23 patients with osteosarcoma, one-third survived for 5 years and 12 (52%) died within a mean of 20 months. Of the 11 patients with chondrosarcoma, 45% survived for 5 years and two (18%) of the patients died within a mean of 6 months. In nine of the osteosarcoma patients (39%) the jaws were involved, and in six of those cases (67%) there was mandibular involvement. Swelling was the first sign in all jaw patients, with a mean age of 41.1 years at diagnosis and a male predominance with a ratio of 8:1. Three of the eight male patients with osteosarcoma of the jaw (38%) died within a mean of less than 1 year. Improved prognosis is related to early recognition and diagnosis to allow for adequate surgical resection. The benefit of a combination of surgery with irradiation or chemotherapy continues to be investigated.

Abstract
Osteosarcomas of the jaws represent less than 10% of all osteosarcomas, and most of them are high-grade neoplasms. Prognostic factors in overall survival include tumor size, location and histologic grade. Examples of well-differentiated (low-grade) intraosseous osteosarcomas of the jaws (WDIOJ) have been rarely reported. This article presents two cases of this unusual lesion, one of which was located in the maxilla of a 17-year-old man and the other developed in the mandible of a 37-year-old woman. CT scan was necessary to detect the small foci of penetration into the thinned cortical bone and the reactive periosteal bone formation, which are important findings to establish the correct diagnosis of WDIOJ and help to exclude other benign intraosseous lesions that may be very similar histologically, such as fibrous dysplasia, ossifying and desmoplastic fibromas. In spite of tumor size (mean 5.2 cm), their well-demarcated borders allowed complete removal of both tumors. There is no evidence of tumoral activity in any of our patients after follow-up periods of 15 months and 5 years. Wide excision seems to be the treatment of choice for this subgroup of osteosarcomas.

Abstract
OBJECTIVE To determine factors including treatment modalities which influence survival in patients with osteosarcoma of the head and neck. STUDY DESIGN Retrospective clinicopathologic study of 27 patients with osteosarcoma of the head and neck. METHODS The clinical charts and pathology slides were reviewed on 27 patients who had osteosarcoma of the head and neck between 1946 and 1998. The following variables were examined for their effect on survival: age of diagnosis, site of tumor, presentation, race, sex, prior radiation exposure, retinoblastoma history, margin status, and method of treatment. RESULTS The average age at the time of diagnosis of the patients was 37.6 years (range, 7-82 y). The sex distribution was similar with 14 male and 13 female patients. Eight of 27 patients had osteosarcoma of the mandible, 9 of 27 had osteosarcoma of the maxilla and paranasal sinuses, and in 10 of 27 patients osteosarcoma occurred elsewhere, including the temporal bones, occipital bones, and orbit. The overall 2-year survival was 66% with a 5-year survival rate of 55%. CONCLUSIONS Positive surgical margins and a high tumor grade were found to have a statistically deleterious effect on overall survival. There was no detectable effect on survival of age, race, sex, prior radiation exposure, tumor site, and tumor cell type. It was not possible to differentiate between the different adjuvant treatment modalities because of the small numbers in the study.

Abstract
OBJECTIVES To categorize the radiological presentation of osteosarcoma of the jaws. METHODS Conventional radiographs and CT scans of nine patients with histologically proven osteosarcoma were reviewed. RESULTS Five patients were men and four women, aged between 20 and 51; four lesions were in the maxilla and five in the mandible. Three radiological presentations of osteosarcoma of the jaw were identified. The first was radiolucent, characterized by a total absence of bone formation within the tumour. The second had a mottled appearance with small areas of amorphous ossification separated by non-ossified tumour tissue. The third, with lamellar ossification, was typically characterized by bony plates irradiating from a focus like a 'sunburst'. CONCLUSION Radiological diagnosis of osteosarcoma of the jaw can be difficult because of its variable appearance. CT is particularly useful.

Abstract
Two cases of low-grade intraosseous osteosarcomas are reported, bringing the total number of such osteosarcomas in the jawbones documented in recent literature to six. Our first case involved the maxilla of a 69-year-old man and the second involved the mandible of an 18-year-old girl. In clinical and microscopic appearance, these neoplasms resemble benign proliferations in many respects. Subtle differences include cortical bone destruction, soft tissue infiltration, irregular bone production with foci of abundant osteoid, and mild cellular atypia. Complete removal at the first attempt is of paramount importance, inasmuch as a significant percentage of these neoplasms recur as high-grade osteosarcomas if they are inadequately treated.

Abstract
Osteosarcoma of the jaw bone is comparatively rare and accounts for about 6.5% of all osteosarcomas. We treated eight cases of osteosarcoma of the jaw bone involving the mandible and maxilla in equal proportions between 1986-1992. The median age was 31 years and male: female ratio was 5:3. Swelling and bony expansion were the most common presentations. Radiologically six patients had lytic lesions, and histopathologically they were osteoblastic (n = 4), chondroblastic (n = 3) and fibroblastic (n = 1). Three patients, two with mandibular and one with maxillary osteosarcoma underwent radical surgery and six courses of cisplatinum-based chemotherapy. All were alive and disease free 24, 30, and 54 months after treatment. Histologically all three were chondroblastic. Five patients had incomplete or palliative treatment. All patients died of progressive or locally recurrent disease within 2 years.

Abstract
BACKGROUND Head and neck osteosarcoma is a comparatively rare and aggressive malignancy. Our goal was to examine the experience of head and neck osteosarcoma patients seen over a 15-year period at the University of Washington Medical Center and compare this with the published experience of other centers in terms of demographics, histology, treatment, and survival rate. METHODS We reviewed surgical pathology slides and clinical treatment records of 13 patients who were treated at the University of Washington Medical Center between 1981 and 1996. A total of 17 cases from 13 patients (13 primary tumors and 4 recurrences) were studied. RESULTS There was a slight male predominance, with a male:female ratio of 1.6:1, and median age at diagnosis of 40.9 years (range 22 to 75 years), both slightly higher than has been generally reported. Three of 13 patients had recognized risk factors for the development of osteosarcoma: 2 with a history of prior radiotherapy and 1 with Paget's disease. All surgical pathology specimens were examined independently by two pathologists for histologic grading and typing. At initial presentation, 9/13 (69%) cases had conventional (osteoblastic) histology; 2/13 (15%) were fibroblastic, 1 chondroblastic (8%) and 1 parosteal (8%). Eight of 13 (62%) cases were high grade at initial presentation. Four of 13 (30%) of the primary tumors were low grade 2, of which did not recur over a median follow-up period of 24 months. The other 2 low-grade tumors later recurred locally, as high-grade osteosarcomas, after disease-free intervals of 1 year and 14 years, respectively. One patient had an intermediate-grade tumor which has not recurred as of last follow-up. Combined-modality treatment, including surgery with or without radiotherapy and/or chemotherapy, was given depending on the histologic grade, surgical margins, and recurrence. Some patients with low-grade tumors had surgery only. There were 5 local recurrences, 1 of these following a disease-free interval of 14 years. One patient had 3 separate recurrences at the same site. Ten of 13 (77%) are alive and disease-free. Of the 3 deaths, 1 was related to radiation-induced brain necrosis, without evidence of recurrent tumor. The project 5-year overall survival in this series is 72%, with a mean follow-up of 58 months (median, 36 months). Of those receiving neoadjuvant chemotherapy, 6/7 have survived to the present. CONCLUSION Given the limitations of a small patient population, our data suggest that neoadjuvant chemotherapy may provide benefit in terms of survival. Longer follow-up will be necessary to support this conclusion. Our data also show that our population has a higher-than-average age of onset, low presence of risk factors, and better survival rate in comparison with the published series from other institutions.
