Radiographs are essential for the initial diagnosis of chondrosarcoma; radiography is sometimes supplemented with computed tomography (CT) scanning, which is more sensitive for detecting matrix. Chondrosarcoma is a malignant tumor that produces cartilage matrix. There are many confusing issues concerning the imaging feature that can facilitate early diagnosis and the factors that might be related to outcomes. Tumour excision with wide margins should provide the best prognosis although this is often difficult due to the proximity of vital structures. Find out about the symptoms, causes, and treatment of chondrosarcoma, a type of bone cancer most common in your pelvis, thighbone, or upper arm. Most often occurs in 5th or 6th decades. Chondrosarcoma is a type of sarcoma (bone or soft tissue cancer) that consists of cartilage-producing cells. The tumor itself . The mass may contain calcifications and lead to diagnostic confusion, raising the possibility of osteosarcoma or chondrosarcoma. Introduction. Resection of tumors with wide margins gained popularity with advances in the medical field. Approximately 85% of chondrosarcomas are low grade, with a risk of developing into high grade or de-differentiated chondrosarcomas. With radiation therapy, the mean survival time of nasal chondrosarcoma is approximately 1-2 years. Chondrosarcoma. . Large soft tissue mass is common. The demographic, prognostic, and outcome data of chondrosarcoma are well documented. Hindquarter amputation was the standard treatment for pelvic osteosarcoma for years. Tests of liver, lung, and renal functionwith bone biochemical analysesmay be used for preoperative assessment and for evaluations of the distant spread of tumors (metastasis). Based on the morphologic feature alone, a correct diangosis of CHS may be difficult, Therefore, correlation of radiological and clinicopathological features is mandatory in the diagnosis of CHS. Magnetic resonance imaging (MRI) and CT (computed tomography) scans provide more detailed images of the areas around your bones and are usually obtained before any treatment. Chondrosarcoma is an uncommon malignant neoplasm of cartilaginous origin; fewer than 10% of all cases of chondrosarcoma occur in the craniofacial region (), making craniofacial chondrosarcoma a rare disease entity.Chondrosarcoma of the craniofacial region may arise from any bone, cartilaginous, or soft-tissue structures but most commonly involves the mandible, maxilla, or cervical vertebrae (). Localization: Proximal femur, pelvis, proximal humerus, scapula, and proximal tibia. Radiation might be recommended for chondrosarcomas located in places that make surgery tricky or if the cancer can't be removed completely during surgery. Share Add to. [2] It is resistant to chemotherapy and radiotherapy. The pelvis is the most common site with iliac bone being frequently involved. the weighted kappa coefficients were higher in long-bone chondrosarcoma than in pelvic chondrosarcoma for the determination of histological . 8.4. 1, 2 Chondrosarcoma usually occurs in the pelvis, humerus, and proximal femur . Although less often, other areas (such as the ribs) may be affected. By contrast, grade III lesions are associated with a poor prognosis with the highest local recurrence rates, a lung metastasis rate of >50%, and a . Sometimes permeative. haracterized by focal, dull, aching pain to the affected region. Grade is a well-recognized prognostic factor in these tumors. This can help guide treatment decisions. The diagnosis was a grade 2 central chondrosarcoma. Chondrosarcoma happens most often in the pelvis, hip and shoulder. interventional radiology performed two sessions of RFA treatment at 100C for approximately 3 min each session. Your doctor may also use spinal angiography to get detailed images of your spine's arteries and veins. This kept significance also in multivariate analysis. Frequently calcifies with punctate or circular opacities. In general chondrosarcomas are large masses at the time of diagnosis, usually >4 cm in diameter and >10 cm in 50% of cases. Background: Treatment of pelvic chondrosarcoma is a difficult problem for the musculoskeletal oncologist. Chondrosarcoma Chondrosarcoma is a bone sarcoma, a primary cancer composed of cells derived from transformed cells that produce cartilage. Our 5 and 10-year survival rates in those patients are 50 and 42%, respectively. Most chondrosarcomas grow slowly and may not cause many signs and symptoms at first. Imaging diagnosis--spinal cord chondrosarcoma associated with spirocercosis in a dog Vet Radiol Ultrasound. Chondrosarcoma. The most frequent primary sites are the pelvis, shoulder, ribs, or at the ends of the arms and legs. MRI is commonly used to study the spine or pelvis after therapeutic irradiation. 1 Chondrosarcoma typically affects adults between the age of 20 and 60 years old, and it is more common in men. They are commonly found in Caucasians 3. Current treatment for pelvic dedifferentiated CS consists of either palliative, limb-salvage through pelvic resection with or without reconstruction, or limb-sacrifice with hindquarter amputation [5, 6]. Destruction of bone occurs late in disease. The authors present a case of chondrosarcoma of the upper end of the femur of a 50-year-old female patient who has come in our . Cancer surgeons who specialize in bone and soft tissue tumors (orthopedic oncologists) lead the care team for most people with chondrosarcomas. Radiation would be used as an . . In the pelvis and at more advanced phases, large soft tissue mass is present. This alteration can be seen 3 months after initiation of therapy, and may remain indefinitely [ 5, 6 ]. with nonmetastatic chondrosarcoma. Chondrosarcoma is a malignant tumor that produces cartilage matrix, and lesions that arise de novo are called primary. About 30% of bone sarcomas are chondrosarcomas. Central Chondrosarcoma. Forty tumors were located in the axial skeleton and the remainder were distributed throughout the appendicular . Solid primary lesions of the hyoid bone are exceedingly rare and the reported cases have included plasmacytoma, osteosarcoma, giant cell tumor, aneurysmal bone cysts, osteoma, chondroma, and chondrosarcoma.3-11 Only 14 cases of chondrosarcoma of the hyoid bone have been . Poor rates of survival and high rates of local recurrence after surgical treatment have been reported in previous studies. Chondrosarcoma. Mesenchymal chondrosarcoma is a malignant biphasic neoplasm characterized by a primitive small round cell sarcoma admixed within a low-grade hyaline cartilage tumor ( Fig. The WHO 2013 classification system has reclassified grade 1 conventional chondrosarcoma as an atypical cartilaginous tumor/chondrosarcoma grade I ( ACT/CS1 ). There are numerous types of primary chondrosarcomas, including conventional intramedullary, clear cell, juxtacortical, myxoid . (a) AP radiograph of the pelvis shows a predominantly sclerotic mass centered along left sacroiliac joint (arrow). In long bones, it starts metaphyseal extending as far as half or more of the entire bone. Grade I lesions/atypical cartilaginous tumors rarely metastasize, rarely recur, and have a 10-year survival rate of >80%. 2010 Nov-Dec;51(6):614-6. doi: 10. . Diagnosis certain. Chondrosarcoma is a type of sarcoma that affects the bones and joints. The only resection without reconstruction of the pelvis has its own . High-grade chondrosarcoma of the pelvis. Most often geographic bone lesion. X-rays aren't used as often to detect chondrosarcoma. The potential morbidity of wide resection, particularly in the periacetabular region, is substantial. Chondrosarcoma (CHS) is the third most common primary bo ne tumor after myeloma and osteosarcoma. Chondrosarcoma of the pelvis is 1 of the most challenging tumors for the orthopaedic surgeon. PATIENTS AND METHODS Eighty patients had chondrosarcoma diagnosed and were treated between 1970 and 1993. Epidemiology Chordomas can occur at any age but are usually seen in adults (30-70 years). Primary chondrosarcoma is the third most common primary malignant tumor of bone, constituting 20%-27% of all primary malignant osseous neoplasms. Chondrosarcoma of the nasal passages has a more guarded prognosis. In the case of pelvic chondrosarcoma, conventional oncology treatment has been complete wide resection. Chondrosarcoma is a slow-growing malignant neoplasm that produces a cartilage matrix and is the third most common primary malignant bone tumour after myeloma and osteosarcoma. Frassica FJ, Unni KK, Beabout JW, Sim FH: Dedifferentiated chondrosarcoma . Chondrosarcoma is a rare type of cancer that usually begins in the bones, but can sometimes occur in the soft tissue near bones. Grades 2 and 3 conventional chondrosarcomas are classified as malignant due to metastatic potential. although it has radiographs showed a slightly aneurysmal bone cyst, eosinophilic been hypothesized that cccs is a expansive osteolytic lesion in the left granuloma, and ewing's sarcoma. Chondrosarcoma can affect many areas of the body, but most often . Various imaging . Periosteal chondrosarcoma is a rare low-grade malignant cartilaginous tumor arising from the external surface of bone. Pelvic chondrosarcomas can also involve the proximal femur. The disease usually starts in the bones of the arms, legs or pelvis . More rarely, it can happen in the bones of the spine. Data were gathered on each tumor's histologic grade, extent (intracompartmental versus extracompartmental), resection margin status, and site (axial versus appendicular). Skull base chondrosarcomas can be treated with high-dose radiation therapy, including proton or carbon ion beam radiation therapy Doxorubicin and ifosfamide may prove active in chondrosarcoma,. Plain radiograph lytic (50%) intralesional calcifications: ~70% ( rings and arcs calcification or popcorn calcification) Prognosis Mesenchymal chondrosarcoma is aggressive variant of chondrosarcoma, which tend . Unfortunately, most chondrosarcomas are resistant to chemotherapy [ 2, 4 ]; and many are relatively radioresistant [ 3 ]. A core biopsy can be used to help distinguish this tumor from other, less . Those located in the spheno-occipital region most commonly occur in patients 20-40 years of age, whereas sacrococcygeal chordomas are typically seen in a slightly older age group (peak around 50 years 10 ). Approximately 40% of conventional chondrosarcomas arise from the shoulder girdle, chest wall and pelvis. Under an Elsevier user license Open archive Introduction Chondrosarcoma (CS) is a malignant skeletal tumor with cartilaginous differentiation. [3,4] . hyaline cartilage differentiation. Radiographic features Useful features include: size lesion size over 5-6 cm favors chondrosarcomas cortical breach seen in 88% of long bone chondrosarcomas seen in only 8% of enchondromas deep endosteal scalloping involving > 2/3 of cortical thickness seen in 90% of chondrosarcomas seen in only 10% of enchondromas Conventional chondrosarcoma constitutes 85% of chondrosarcomas. Surgery included the reconstruction of the acetabulum by inserting two Schanz pins coated with hydroxyapatite, one in the iliopubic corridor and the other in . If the chondrosarcoma cannot be excised, the other treatment option is curettage with thermal ablation (or adjunct chemotherapy). Wide en bloc resection with clear margins is usually curative (Am J Surg Pathol 1984;8:223, Clin Orthop Relat Res 2020;478:2537) Clear cell chondrosarcoma can recur locally or distantly in the bones and lungs in the long term; therefore, patients should be informed of the risk of very late recurrence and the necessity for decades of surveillance to detect any local recurrence or lung and bone . 7 ). The 5-year survival rate for chondrosarcoma is 75.2%, which is much higher than that of osteosarcoma and Ewing sarcoma 3. As highly significantly shown in our data, pelvic location of a chondrosarcoma has a worse prognosis. The patient . Chondrosarcoma primarily affects the cartilage cells of the femur (thighbone), arm, pelvis, or knee. In retrospect, there are many features of the case we presented which were reviewed. Chondrosarcoma (CS) is the second most frequent primary malignant bone tumor after osteosarcoma. Chondrosarcoma is a collective term for a group of tumors that consist predominantly of cartilage and that range from low-grade tumors with low metastatic potential to high-grade, aggressive. Chondrosarcoma is a type of cancer that forms in bone cartilage. A primary bone cancer is one that starts from bone. Background Dedifferentiated chondrosarcoma is a rare, highly malignant tumor with a poor survival. (b, c) Axial T1W and STIR MR images show a lobulated mass arising from the posterior iliac bone with cortical destruction and extension into the adjacent soft tissue (arrows). Also femur, tibia, humerus. Central (conventional) CS represents about 75% of the group. It is a rare cancer that accounts for about 20% of bone tumors and is diagnosed in approximately 600 patients each year in the United States. Discussion. The cohort included 60 males and 49 females with a mean age of 50 years. This pictorial review describes the MRI features which may aid in the differentiation of Grade 1 chondrosarcoma (Gd1-CS) from high-grade chondrosarcoma (HG-CS) and dedifferentiated chondrosarcoma (DD-CS) in these locations, based on literature review and assessment of 111 consecutive cases . On imaging, these tumors have ring-and-arc chondroid matrix mineralization with aggressive features such as lytic pattern, deep endosteal scalloping and soft-tissue extension. [1] A chondrosarcoma is a member of a category of tumors of bone and soft tissue known as sarcomas. It constitutes a heterogeneous group of tumors characterized by the production of cartilaginous matrix [ 2 ]. Other specialists are included as needed. Typically in the pelvis, femur, humerus; Has been reported arising in a solitary osteochondroma dedifferentiated component can be leiomyosarcoma, osteosarcoma, MFH, and fibrosarcoma . The images will show blood flow around the chondrosarcoma, and will help your doctor understand what blood vessels are impacted by the tumor. Dedifferentiated chondrosarcoma is an aggressive subtype of chondrosarcoma that is characterized by a cartilaginous component and a highly lytic sarcomatous component. Pathology proven case of chondrosarcoma in a 70 years old male. Due to the wide spectrum of radiographic appearances, ES can mimic most malignant and a few benign entities, including osteomyelitis, eosinophilic granuloma, and giant cell tumor [ 8 ]. Radiofrequency ablation is another minimal invasive percutaneous technique used mainly for palliating painful skeletal metastasis [ 53 - 55 ], including the spine region [ 56 ], but there is no study, to our knowledge, addressing the application of this technique in primary spinal tumors and more specifically chondrosarcoma. Primary chondrosarcoma is the third most common primary malignant tumor of bone, constituting 20%-27% of all primary malignant osseous neoplasms. Chondrosarcoma is a malignant mesenchymal tumor that produces cartilage matrix. Symptoms may include: a large lump on a bone progressively worsening pain pressure. Radiographically, there is often an abrupt transition between these tissue types within the lesion. On T1-weighted MRI, there is an increased signal in the involved bone due to replacement of the hematopoietic marrow with fat. Chondrosarcoma is the second most common type of primary bone cancer. The diagnosis of a chondrosarcoma of the hyoid bone may be missed because of its infrequent occurrence. Radiation may also be used to control cancer that spreads to other areas of the body. The histological grade should be correlated with imaging and the clinical presentation, but under these circumstances, experienced tumor surgeons may use this information in planning surgical treatment. The most common places that develop chondrosarcoma are your pelvis or the long bones in your arms and legs. Occurs in the fourth to sixth decades and has a male to female ratio of 2/1. Known as dedifferentiated chondrosarcomas, these tumors are highly malignant with a very poor prognosis. Mesenchymal chondrosarcoma may affect patients of all age groups but is commonly seen in both children/young adults and older patients. Advanced imaging such as CT or MRI can further determine cortical destruction and marrow and soft tissue involvement. Abstract Up to 11% of chondrosarcomas may undergo regional anaplastic change, resulting in a high-grade noncartilaginous sarcoma arising within a typically low-grade chondrosarcoma. Chemotherapy Chemotherapy uses drugs to kill cancer cells. There are several subtypes of chondrosarcoma, which vary in terms of location, appearance, treatment and prognosis. Radiographically, there was a poorly mineralized opacity occupying the intervertebral foramen at LA-L5. Methods Twenty-three patients with dedifferentiated chondrosarcoma confirmed by pathology were retrospectively reviewed from 2008 to 2015. Central CS may grow primarily in the medullary canal of healthy bone or may be secondary to pre-existing benign enchondroma [].The prognosis of central CS is directly correlated with the histological grade of malignancy, which is assessed following the criteria described by Evans et al . This location, and especially the peri-acetabular zone, poses difficult specific technical problems when conservative surgery is selected. X-Ray Appearance and Advanced Imaging . Otherwise, workup rests primarily on diagnostic imaging modalities (eg, plain radiography, as well as computed tomography [CT] and magnetic resonance imaging [MRI]). This article reviews and evaluates the oncologic and functional results of 31 patients with chondrosarcoma arising in the pelvic region. Chondrosarcoma is the third most common primary malignant bone tumor. Clinical: Deep, discontinuous, mild pain with small swelling. Chondrosarcoma is the second most common type of primary bone sarcoma and usually occurs in pelvis and long bones 1, 2. . malignant form of chondroblastoma ilium extending to the acetabulum, open biopsy was performed and his- [5,6], it frequently affects individuals with breaching of Other team members may include medical oncologists, radiation oncologists, rehabilitation specialists and neurosurgeons. Case contributed by Dr Roberto Schubert. It is most common in the long bones and on the surface of the pelvis. In terms of incidence, it represents the second most frequent bone tumor in adults [1], and is preferentially located in the pelvis in 22 to 39% of cases [2], [3], [4], [5], [6], [7]. In central chondrosarcomas, published 10-year survival rates vary between 54 and 88% [ 12, 13, 14, 15, 16, 17 ]. Advanced diagnosis and treatment Comprehensive information on Dedifferentiated Chondrosarcoma of bone including signs and symptoms, diagnosis, radiology, pathology, surgery, treatment, prognosis and outcomes . The pelvis's magnetic resonance imaging (MRI) showed an osteolytic tumor in the right iliac wing that compromises the acetabular roof. may be considered if the tumor is unresectable or if a wide margin can not be achieved with surgery such as with large pelvic tumors. typically, chondrosarcomas are found in older patients (40-75 yrs) there is a slight male predominance Anatomic location most common locations include the pelvis, proximal femur, distal femur, scapula tumor location is important for diagnosis as the same histology may be diagnosed as benign in the hand but malignant if located in the long bones
