What is Osteosarcoma?

Osteosarcoma, also known as osteogenic sarcoma, is a type of cancer that starts in the bones. It is the most common type of cancer that begins in the bones and typically affects children and young adults.

Common Signs and Symptoms of Osteosarcoma

Osteosarcoma, a type of bone cancer, can manifest in various ways. The most common symptoms include:

• Bone or joint pain: Pain is often the first symptom, which may come and go at first, but eventually becomes persistent [1]. It can be mistaken for growing pains or other conditions.
• Swelling near the affected area: Swelling and tenderness are common signs of osteosarcoma, especially in the legs and arms [2].
• Bone fractures (breaks): Osteosarcomas can cause weakened bones, leading to unexplained breaks or fractures [3].
• Pain that gets progressively worse over time: As the cancer progresses, pain may radiate from the affected area and worsen with activity or lifting [4].
• Limited range of motion: In some cases, osteosarcoma can cause stiffness or limited movement in the affected limb [5].

It's essential to note that these symptoms can be similar to those of other health conditions. If you're experiencing any of these signs, it's crucial to consult a medical professional for proper diagnosis and treatment.

Diagnostic Tests for Bone Osteosarcoma

Bone osteosarcoma, also known as osteosarcoma, is a type of cancer that affects the bones. Diagnosing this condition requires a combination of physical examination, imaging tests, and laboratory tests.

Imaging Tests

Imaging tests are essential in diagnosing bone osteosarcoma. These tests can show the location and size of the tumor. The following imaging tests may be used:

• X-ray: A conventional plain radiograph is often the best initial test for probable diagnosis, as it can reveal features such as sun burst appearance, Codman's triangle, new bone formation in soft tissues, and a permeative pattern of destruction of the bone [5].
• MRI (Magnetic Resonance Imaging): MRI scans can provide detailed images of the affected bone and surrounding tissue.
• CT (Computed Tomography) scan: CT scans can show the size and location of the tumor.
• Bone scan: A bone scan can reveal areas of high activity in the bones, which may indicate the presence of a tumor.
• Positron emission tomography (PET) scan: A PET scan can help determine if the cancer has spread to other parts of the body.

Biopsy

A biopsy is a procedure where a sample of tissue is removed from the affected bone and examined for cancer cells. This test can confirm whether a growth in the bones is cancerous [3].

Other Tests

In addition to imaging tests, blood tests may be helpful once a diagnosis is made. However, they are not needed to diagnose osteosarcoma.

Multidisciplinary Team Approach

A multidisciplinary team of bone cancer experts uses various tests and tools for diagnosing bone cancer, evaluating the disease, determining the affected bone(s), and developing an individualized treatment plan [8].

Differential Diagnosis of Bone Osteosarcoma

Osteosarcoma, also known as bone cancer, can be challenging to diagnose due to its similarity in appearance with other bone lesions. The differential diagnosis for osteosarcoma includes several conditions that must be ruled out before a definitive diagnosis can be made.

Common Differential Diagnoses:

• Ewing Sarcoma: A type of bone cancer that is more common in children and young adults, Ewing sarcoma can present with similar radiographic features to osteosarcoma [3].
• Chondrosarcoma: A cartilage-based tumor that can mimic the appearance of osteosarcoma on imaging studies [4].
• Osteomyelitis: An infection of the bone that can cause lytic lesions and periosteal reaction, similar to osteosarcoma [5].
• Metastatic Lesions: Tumors from other parts of the body, such as the lung or breast, can metastasize to the bone and mimic the appearance of osteosarcoma [6].

Other Differential Diagnoses:

• Aneurysmal Bone Cyst: A benign tumor that can closely mimic the radiographic features of telangiectatic osteosarcoma, often delaying diagnosis [7].
• Pleomorphic Sarcomas: A type of soft tissue sarcoma that can present with lytic lesions in bone and mimic the appearance of osteosarcoma [8].

Importance of Accurate Diagnosis:

Accurate diagnosis of osteosarcoma is critical for determining appropriate clinical management and predicting patient outcome. The morphologic spectrum of osteogenic sarcoma is extensive, and its histologic mimics are numerous [9]. Therefore, a thorough differential diagnosis must be performed to rule out other conditions that may mimic the appearance of osteosarcoma.
