General Information

 

This cancer treatment information summary provides an overview of the prognosis, diagnosis, classification, and treatment of osteosarcoma and malignant fibrous histiocytoma of bone.

The National Cancer Institute provides the PDQ pediatric cancer treatment information summaries as a public service to increase the availability of evidence-based cancer information to health professionals, patients, and the public. These summaries are updated regularly according to the latest published research findings by an Editorial Board of pediatric oncology experts.

Cancer in children and adolescents is rare. Children and adolescents with cancer should be referred to medical centers that have a multidisciplinary team of cancer specialists with experience treating the cancers that occur during childhood and adolescence. This multidisciplinary team approach incorporates the skills of the primary care physician, an orthopedic surgeon experienced in bone tumors, a pathologist, radiation oncologists, pediatric oncologists, rehabilitation specialists, pediatric nurse specialists, social workers, and others in order to ensure that children receive treatment, supportive care, and rehabilitation that will achieve optimal survival and quality of life. Refer to the PDQ Supportive Care summaries for specific information about supportive care for children and adolescents with cancer.

Guidelines for pediatric cancer centers and their role in the treatment of pediatric patients with cancer have been outlined by the American Academy of Pediatrics.[1] At these pediatric cancer centers, clinical trials are available for most types of cancer that occur in children and adolescents, and the opportunity to participate in these trials is offered to most patients/families. Clinical trials for children and adolescents with cancer are generally designed to compare potentially better therapy with therapy that is currently accepted as standard. Most of the progress made in identifying curative therapies for childhood cancers has been achieved through clinical trials. Information about ongoing clinical trials is available from the NCI Web site.

In recent decades, dramatic improvements in survival have been achieved for children and adolescents with cancer. Childhood and adolescent cancer survivors require close follow-up because cancer therapy side effects may persist or develop months or years after treatment. Refer to the PDQ Late Effects of Childhood Cancer Therapies summary for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.

Osteosarcoma is a bone tumor that occurs predominantly in adolescents and young adults. It accounts for approximately 5% of childhood tumors. In children and adolescents, 80% of these tumors arise from the bones around the knee. Two trials conducted in the 1980s were designed to address the natural history of surgically treated localized, resectable osteosarcoma of the extremity. The outcome of patients in these trials who were treated with surgical removal of the primary tumor only recapitulated the historical experience before 1970; more than half of these patients developed metastases within 6 months of diagnosis, and overall, almost 90% [2] developed recurrent disease within 2 years of diagnosis.[3] Overall survival for patients treated with surgery alone was statistically inferior.[4] The natural history of osteosarcoma has not changed over time, and fewer than 30% of patients with localized resectable primary tumors treated with only surgerycan be expected to survive free of relapse.[3,5-7]

Patients with localized disease have a much better prognosis than those with overt metastatic disease. The site of the primary tumor is a significant prognostic factor in localized disease. Axial skeleton primary tumors are associated with the greatest risk of progression and death.[8,9] Resectability of the tumor is the most important prognostic feature because this tumor is very resistant to radiation therapy. For patients with osteosarcoma of craniofacial bones, complete resection of the primary tumor with negative margins is essential for cure.[10,11] Despite a relatively high rate of poor histologic response to neoadjuvant chemotherapy, very few patients with craniofacial primaries develop systemic metastases .[12-15] Pelvic osteosarcomas make up 7% to 9% of all osteosarcomas; their current overall survival rate is 20% to 47%.[8] Patients with osteosarcoma as a second malignant neoplasm share the same prognosis as patients with newly diagnosed disease if they are treated aggressively with surgery and multiagent chemotherapy.[16-18] There have been numerous other identified prognostic features for patients with conventional localized high-grade osteosarcoma. These include age of patient, tumor volume, skip lesions, lactate dehydrogenase level, alkaline phosphatase level, and histologic subtype.[19-25] A number of potential prognostic factors have been identified but have not been tested in large numbers of patients. These include the expression of HER2/C-erbB-2; [26,27] there are conflicting data concerning the prognostic significance of this human epidermal growth factor),[28] tumor cell ploidy, and specific chromosome gains or losses,[29,30] loss of heterozygosity of the RB gene,[31,32] loss of heterozygosity of the p53 locus,[33] and increased expression of p-glycoprotein.[34-37] The only feature that consistently predicts outcome is the degree of histologic necrosis following induction chemotherapy. Patients with more than 95% necrosis in the primary tumor after induction chemotherapy have a better prognosis than those with smaller amounts of necrosis.[21,38] Imaging modalities such as dynamic magnetic resonance imaging may offer a noninvasive method to assess necrosis.[39]

As many as 20% of patients will have radiographically detectable metastases at diagnosis, with the lung being the most common site.[40] The prognosis for patients with metastatic disease appears to be determined largely by the site(s), the number of metastases, as well as the surgical resectability of the metastatic disease.[6,40-42] Patients who have complete surgical ablation of the primary and metastatic tumor (when confined to the lung) following chemotherapy may attain long-term survival, though overall event-free survival remains about 20% to 30% for patients with metastatic disease at diagnosis.[6,38,40,43] Prognosis appears more favorable for patients with unilateral rather than bilateral pulmonary metastases, and for patients with fewer nodules rather than many nodules.[6,41] The degree of necrosis in the primary tumor after induction chemotherapy remains prognostic in metastatic osteosarcoma.[23] Patients with skip metastases (≥2 discontinuous lesions in the same bone) have been reported to have inferior prognoses.[44] Patients with multifocal osteosarcoma (>1 bone lesion at diagnosis) have a poor prognosis.[45]

Patients with malignant fibrous histiocytoma of bone (MFH) are treated according to osteosarcoma protocols, and the outcome for patients with resectable MFH is similar to the outcome for patients with osteosarcoma.[46] As with osteosarcoma, patients with a good histological response had a longer survival than those with a poor response.[47]

Cellular Classification

Central (Medullary) Tumors
Surface (Peripheral) Tumors

 

 

Osteosarcoma is a primary malignant tumor of the appendicular skeleton that is characterized by the direct formation of bone or osteoid tissue by the tumor cells. The World Health Organization’s histologic classification [1] of bone tumors separates the osteosarcomas into central (medullary) and surface (peripheral) [2] tumors and recognizes a number of subtypes within each group.

Central (Medullary) Tumors
  • Conventional central osteosarcoma.

     
  • Telangiectatic osteosarcoma.

     
  • Intraosseous well-differentiated (low-grade) osteosarcoma.

     
  • Small cell osteosarcoma.

     
Surface (Peripheral) Tumors
  • Parosteal (juxtacortical) well-differentiated (low-grade) osteosarcoma.

     
  • Periosteal osteosarcoma: low-grade to intermediate-grade osteosarcoma.

     
  • High-grade surface osteosarcoma.[3]

     

The most common pathologic subtype is conventional central osteosarcoma, which is characterized by areas of necrosis, atypical mitoses, and malignant osteoid tissue and/or cartilage. The other subtypes are much less common, each occurring at a frequency of less than 5%. Telangiectatic osteosarcoma may be confused radiographically with an aneurysmal bone cyst or giant cell tumor. This variant should be approached as a conventional osteosarcoma.[4] Recognition of intraosseous well-differentiated osteosarcoma and parosteal osteosarcoma is important because these are associated with the most favorable prognosis and can be treated successfully with radical excision of the primary tumor alone. Periosteal osteosarcoma has an intermediate prognosis [5] and treatment is guided by histologic grade.

Malignant fibrous histiocytoma of bone (MFH) is treated according to osteosarcoma protocols. MFH should be distinguished from angiomatoid fibrous histiocytoma, a low-grade tumor that is usually noninvasive, small, and associated with an excellent outcome with surgery alone.[6] One study suggests that event-free survival for MFH and osteosarcoma is similar.[7]

Extraosseous osteosarcoma is a malignant mesenchymal neoplasm without direct attachment to the skeletal system. Treatment for extraosseous osteosarcoma should follow soft tissue sarcoma guidelines rather than guidelines for osteosarcoma of bone.[8] Refer to the PDQ Childhood Soft Tissue Sarcoma Treatment summary for more information about the treatment of soft tissue sarcoma.

Stage Information

Localized Osteosarcoma
Metastatic Osteosarcoma

 



Localized Osteosarcoma

Localized tumors are limited to the bone of origin; local skip metastases may be apparent within the bone and are associated with a worse prognosis.[1] Approximately one half of the tumors arise in the femur; of these, 80% are in the distal femur. Other primary sites in descending order of frequency are the tibia, humerus, pelvis, jaw, fibula, and ribs.[2] Osteosarcoma of the head and neck is more likely to be low-grade than osteosarcoma of the appendicular skeleton [3] and is more likely to arise in older patients. There is a better prognosis for patients who have osteosarcoma of the head and neck than for those who have appendicular lesions when treated with surgery. While small series have not shown a benefit from adjuvant chemotherapy for patients with osteosarcoma of the head and neck, one meta-analysis concluded that systemic chemotherapy improves the prognosis for patients with osteosarcoma of the head and neck.[3,4] Another large meta-analysis detected no benefit from chemotherapy for patients with osteosarcoma of the head and neck, but suggested that incorporation of chemotherapy into treatment of patients who have high-grade tumors may improve survival.[5]

Metastatic Osteosarcoma

Radiologic evidence of metastatic tumor deposits in lung, other bones, or other distant sites is found in 10% to 20% of patients at diagnosis; 85% to 90% of metastatic disease is in the lungs. The second most common site of metastasis is another bone.[6] Presentations with multiple bone metastases carry an extremely grave prognosis.[2]

Treatment Option Overview

 

Randomized clinical trials have established that both neoadjuvant and adjuvant chemotherapy are effective in preventing relapse in patients with nonmetastatic occult tumors.[1,2] It is imperative that patients with proven or suspected osteosarcoma have an initial evaluation by an orthopedic oncologist familiar with the surgical management of this disease. This evaluation, which includes imaging studies, should be done prior to the initial biopsy, since an inappropriately performed biopsy may jeopardize a limb-sparing procedure.

The designations in PDQ that treatments are “standard” or “under clinical evaluation” are not to be used as a basis for reimbursement determinations.

Localized Osteosarcoma/Malignant Fibrous Histiocytoma of Bone

Treatment options
 

 

Complete surgical resection is crucial for patients with localized osteosarcoma; however, at least 80% of patients treated with surgery alone will develop metastatic disease.[1,2] Randomized clinical trials have established that adjuvant chemotherapy is effective in preventing relapse or recurrence in patients with localized resectable primary tumors.[1,3]

A number of single-arm trials evaluated the role of chemotherapy administered both preoperatively and postoperatively. Some of these trials evaluated the necrosis of the primary tumor following chemotherapy and used this information to determine subsequent therapy.[4,5] Current chemotherapy protocols include combinations of the following agents: high-dose methotrexate, doxorubicin, cyclophosphamide, cisplatin, ifosfamide, etoposide, and carboplatin.[5-14] Overall, relapse-free survival ranges between 50% to 75% in these trials.[4,13] One randomized trial found no difference in survival between 2 drugs given for a shorter duration and multiagent regimens, though event-free survival in both arms was less than 50%.[15]

All patients with osteosarcoma should undergo surgical resection of the primary tumor if possible. The type of surgery required for complete ablation of the primary tumor depends on a number of factors that must be evaluated on an individual basis. If limb-sparing (removal of the malignant bone tumor without amputation and replacement of bones or joints with allografts or prosthetic devices) is contemplated, the biopsy should be performed by the surgeon who will do the definitive operation, since incision placement is crucial. While a needle biopsy can often confirm the diagnosis, participation in some clinical trials requires collection of material for biologic studies that can only be obtained via an open biopsy or multiple needle biopsies. Rotationplasty and limb-sparing procedures have been evaluated for both functional result and effect on survival.[16] There is no difference in overall survival between patients initially treated by amputation and those treated with a limb-sparing procedure.[17] One randomized trial noted no difference in disease-free survival between preoperative chemotherapy compared with immediate surgery followed by adjuvant chemotherapy.[18] Limb-sparing procedures should be planned only when the preoperative staging indicates that it is possible to achieve wide surgical margins. A pathologic fracture noted at diagnosis or during preoperative chemotherapy does not preclude limb-salvage surgery if wide surgical margins can be achieved.[19] In one series, patients presenting with a pathologic fracture at diagnosis had similar outcomes to those without pathologic fractures at diagnosis.[20] If the pathologic examination of the surgical specimen shows inadequate margins, an immediate amputation should be considered, especially if the histologic response to preoperative chemotherapy was poor.[17] In one study, patients undergoing limb-salvage procedures who had poor histologic response and close surgical margins had a high rate of local recurrence.[21] For patients who receive chemotherapy prior to surgery, the degree of tumor necrosis observed postoperatively is highly predictive of disease-free survival, local recurrence, and overall survival.[7,8,22] Increasing the intensity of preoperative chemotherapy raised the proportion of patients with good histologic response in one study [23] but not in another.[24] There is no evidence that increased intensity of preoperative therapy is associated with improved overall survival. Patients with primary tumors of the femur have a higher local recurrence rate than do patients with primary tumors of the tibia/fibula. Not surprisingly, patients who undergo amputation have lower local recurrence rates than patients undergoing limb-sparing procedures.[22] In general, more than 80% of patients with extremity osteosarcomas can be treated by a limb-sparing operation and do not require amputation.[4] While limb-sparing tumor resection is the current practice for local control at most pediatric institutions, there are few data to indicate that limb-salvage of the lower limb is substantially superior to amputation in regard to patient quality of life.[25] Patients with pelvic osteosarcoma may benefit from radiation therapy if surgical margins are inadequate.[26] Information about ongoing clinical trials is available from the NCI Web site.

Treatment options

Localized, completely resectable high-grade osteosarcoma

  • Most patients receive preoperative (neoadjuvant) chemotherapy followed by extirpative surgery (amputation, limb salvage, or rotationplasty) [16] and postoperative adjuvant chemotherapy. In some trials, the type of postoperative adjuvant chemotherapy is determined by the degree of necrosis observed in the primary tumor.

     
  • Preoperative chemotherapy (either systemically or intra-arterially) followed by extirpative surgery (amputation, limb salvage, or rotationplasty).[9,16] After surgery, tumor necrosis is used to determine degree of response to the initial chemotherapy. If tumor necrosis exceeds a preset level (90%-95%), the preoperative chemotherapy regimen is continued; if necrosis is inferior, an alternative regimen is used.[4,27] This approach has not been examined in a randomized study.

     

For lesions that cannot be removed, clinical studies are now being conducted using a phase II/III approach or using intensive combination chemotherapy and high-dose, very well-collimated and localized radiation.

For patients with malignant fibrous histiocytoma of bone (MFH), wide local excision is recommended regardless of tumor grade. Most patients with MFH will need preoperative chemotherapy to achieve a wide local excision.[28]

Osteosarcoma

The progression-free survival rate for patients with metastatic osteosarcoma at diagnosis is approximately 20%.[1-4] Patients with only pulmonary metastatic disease have a better survival rate (approximately 40%).[1-3] Prognosis for these patients appears to be more favorable with unilateral rather than bilateral pulmonary metastases, and for patients with fewer nodules and lobes involved.[1,3,5,6] Patients with multifocal bone disease at presentation have an extremely poor prognosis, but systemic chemotherapy and aggressive surgical resection may achieve significant prolongation of life.[7] Multifocal osteosarcoma classically presents with symmetrical, metaphyseal lesions, and it may be difficult to decide which is the primary lesion. Patients with a more conventional presentation of a large primary lesion may have ≥1 bone metastases in the same bone (skip lesions) or in distant bones. Patients with a skip lesion and no other sites of metastatic disease have a poor outcome.[8] Patients with bony metastases have a poor prognosis, though treatment of patients using etoposide and ifosfamide may offer some improvement in outcome.[7,9] In a review of patients with primary metastatic extremity osteosarcoma, the long-term survival for patients with skip lesions was greater than 50%.[3] Aggressive management, including surgical removal of primary and all metastatic disease at the time of diagnosis or after intensive multiagent regimens, is necessary. All patients should receive intensive multiagent chemotherapy whether or not the primary and metastatic lesions are surgically resectable.[4]

The most frequently used approach is preoperative chemotherapy followed by surgical ablation of the primary tumor and resection of all overt metastatic disease. This is followed by postoperative combination chemotherapy. The chemotherapeutic agents used include high-dose methotrexate, doxorubicin, cisplatin, high-dose ifosfamide, etoposide, and in some reports, carboplatin or cyclophosphamide.

An alternative approach is surgical ablation of the primary tumor and metastases, where possible, followed by combination chemotherapy. This approach may be appropriate in patients with intractable pain, pathologic fracture, or uncontrolled infection of the tumor where initiation of chemotherapy could create risk of sepsis. The chemotherapeutic regimens utilized in the treatment of metastatic osteosarcoma include high-dose methotrexate, doxorubicin, cyclophosphamide, cisplatin, ifosfamide, etoposide, and carboplatin.

Information about ongoing clinical trials is available from the NCI Web site.

Malignant Fibrous Histiocytoma of Bone

Patients with unresectable or metastatic malignant fibrous histiocytoma of bone have a very poor outcome.[10]

Recurrent Osteosarcoma

 

Most recurrences of osteosarcoma develop within 2 to 3 years after treatment completion. Late recurrences are rare, occuring in 0.6% to 3.7% of patients.[1] Recurrence of osteosarcoma is most often in the lung. Patients with recurrent osteosarcoma should be assessed for surgical resectability, as they may sometimes be cured with aggressive surgical resection with or without chemotherapy.[2-6] The ability to achieve a complete resection of recurrent disease is the most important prognostic factor at first relapse, with a 5-year survival rate of 20% to 45% following complete resection of metastatic pulmonary tumors and 20% following complete resection of metastases at other sites.[6] Survival for patients with unresectable metastatic disease is less than 5%.[6,7] Factors that suggest a better outcome include fewer pulmonary nodules, unilateral pulmonary metastases, [8] or longer intervals between primary tumor resection and metastases.[6,9] The lung is the most common site of recurrence for osteosarcoma. Resection of metastatic disease followed by observation alone results in low overall and disease-free survival. Factors associated with better outcome include solitary pulmonary nodule, unilateral lung involvement, longer interval from initial diagnosis, and achieving a second complete remission.[10,11] In several small series, patients with metachronous bone recurrence have an approximate 40% salvage rate; late metachronous recurrence more than 24 months from initial diagnosis is more favorable than early metachronous recurrence.[12-14] A high percentage of patients with pulmonary nodules identified in only one lung who underwent staged bilateral thoracotomy were found to have palpable nodules in both lungs that were not visualized on CT scan. This suggests that patients with unilateral nodules may benefit from bilateral exploration.[8] The postrelapse outcome of patients who have a local recurrence is worse than that for patients who relapse with metastases alone.[15-17] The incidence of local relapse was higher in those patients who had a poor pathologic response of the primary to chemotherapy in the primary tumor.[15] The selection of further treatment depends on many factors, including the site of recurrence, the patient’s previous primary treatment, and individual patient considerations. Ifosfamide alone with mesna uroprotection, or in combination with etoposide, has shown activity in as many as one third of patients with recurrent osteosarcoma who have not previously received this drug.[18-20] Cyclophosphamide and etoposide have activity in recurrent osteosarcoma.[21] Peripheral blood stem cell transplant utilizing high-dose chemotherapy does not appear to improve outcome.[22,23] Clinical trials (phases I and II) are appropriate for patients with unresectable metastatic disease and should be considered. High-dose samarium-153-EDTMP coupled with peripheral blood stem cell support may provide significant pain palliation in patients with bone metastases.[24,25]

Osteosarcoma: A Multidisciplinary Approach to Diagnosis and Treatment

The treatment of osteosarcoma requires a multidisciplinary approach involving the family physician, orthopedic oncologist, medical oncologist, radiologist and pathologist. Osteosarcoma is a mesenchymally derived, high-grade bone sarcoma. It is the third most common malignancy in children and adolescents. The most frequent sites of origin are the distal femur, proximal tibia and proximal humerus. Patients typically present with pain, swelling, localized enlargement of the extremity and, occasionally, pathologic fracture. Most patients present with localized disease. Radiographs commonly demonstrate a mixed sclerotic and lytic lesion arising in the metaphyseal region of the involved bone. Computed tomography and bone scanning are recommended to detect pulmonary and bone metastases, respectively. Before 1970, osteosarcomas were treated with amputation. Survival was poor: 80 percent of patients died from metastatic disease. With the development of induction and adjuvant chemotherapy protocols, advances in surgical techniques and improvements in radiologic staging studies, 90 to 95 percent of patients with osteosarcoma can now be treated with limb-sparing resection and reconstruction. Long-term survival and cure rates have increased to between 60 and 80 percent in patients with localized disease. (Am Fam Physician 2002;65:1123-32,1135-6.

Bone sarcomas are rare mesenchymally derived high-grade tumors. Approximately 2,500 cases per year are diagnosed in the United States.1 Osteogenic sarcoma is the most common bone sarcoma and the third most common malignancy in children and adolescents. The most frequent sites of origin are the metaphyseal regions of the distal femur, proximal tibia and proximal humerus, although the tumor can develop in any bone.2,3

{short description of image}
Most osteosarcomas develop in patients 10 to 20 years of age. Patients typically present with dull aching pain of several months' duration that may suddenly become more severe.
{short description of image}

Family physicians and pediatricians are often the first clinicians to encounter patients with osteosarcoma. Consequently, these physicians need to be familiar with the clinical presentation and overall management of this malignancy.

Most osteosarcomas are classified as conventional, high-grade tumors.2-4 Before 1970, amputation was the sole treatment for a high-grade osteosarcoma, and 80 percent of patients died of metastatic disease, most commonly to the lungs.2 Over the past three decades, effective induction (neoadjuvant/preoperative) and adjuvant (postoperative) chemotherapy protocols have improved the ability to perform safe limb-sparing resections, and disease-free and overall survival rates have risen. Today, 90 to 95 percent of patients with osteosarcoma can be treated with limb-sparing surgery, and 60 to 80 percent of patients with localized disease are long-term survivors.5-7

Biologic Behavior of Osteosarcoma

An osteosarcoma grows in a radial manner, forming a ball-like mass. When it penetrates the bony cortex, it compresses the surrounding muscles into a pseudocapsular layer referred to as the "reactive zone." Tumor nodules representing microextensions of the primary mass invade the reactive zone. These nodules are termed "satellites." The
