Osteosarcoma Diagnosis

How is osteosarcoma diagnosed?

A bone scan is a way to find out whether or not osteosarcoma may have spread to other bones beyond the place it started. Biopsy. A biopsy is the removal of a small amount of tissue for examination under a microscope. Other tests can suggest that a tumor is present, but only a biopsy can make a definitive diagnosis.

What are the most significant symptoms of osteosarcoma?

The most common symptoms of osteosarcoma include:
  • Bone pain or tenderness.
  • A mass or lump (tumor) that is warm and might be felt through your skin.
  • Swelling and redness at the site of your tumor.
  • Increased pain with lifting (if it affects your arm).
  • Limping (if it affects your leg).

What is the most common age to be diagnosed with osteosarcoma?

It is most often diagnosed between the ages of 10 and 30, with most of these diagnoses occurring in teens. However, osteosarcoma can be diagnosed at any age, including in older adults. Around 10% of osteosarcoma is diagnosed in people over age 60.

Can osteosarcoma be detected in a blood test?

Blood tests. Blood tests are not needed to diagnose osteosarcoma, but they may be helpful once a diagnosis is made. For example, high levels of chemicals in the blood such as alkaline phosphatase and lactate dehydrogenase (LDH) can suggest that the osteosarcoma may be more advanced.

Can osteosarcoma be seen on ultrasound?

So it may come to a conclusion that plain radiography combined with ultrasonography can completely display the bony and soft tissue lesion of osteosarcomas.

What does bone pain feel like?

What is bone pain? Bone pain is extreme tenderness, aching, or other discomfort in one or more bones. It differs from muscle and joint pain because it’s present whether you’re moving or not. The pain is commonly linked to diseases that affect the normal function or structure of the bone.

Where does osteosarcoma start?

In children, teens, and young adults, osteosarcoma usually starts in areas where the bone is growing quickly, such as near the ends of the leg or arm bones: Most tumors develop in the bones around the knee, either in the lower part of the thigh bone (distal femur) or the upper part of the shinbone (proximal tibia).

How can you tell the difference between muscle pain and bone pain?

Bone pain usually feels deeper, sharper, and more intense than muscle pain.

Is osteosarcoma a death sentence?

The 5-year survival rate of people with osteosarcoma is 60%. If the cancer is diagnosed at the localized stage, the 5-year survival rate is 74%. If the cancer has spread to surrounding tissues or organs and/or the regional lymph nodes, the 5-year survival rate is 66%.

Can you survive stage 4 osteosarcoma?

According to the American Ca ncer Society, the five-year relative survival rate for the most advanced st age of osteosarcoma is 27 percent.

Is osteosarcoma malignant or benign?

Malignant bone tumors can occur at almost any age. Osteosarcoma and Ewing’s sarcoma, two of the most common malignant bone tumors, are usually found in people age 30 or younger. In contrast, chondrosarcoma, malignant tumors that grow as cartilage-like tissue, usually occur after the age of 30.

Can MRI detect bone metastases?

Whole-body MRI and PET-CT are now the most sensitive and specific methods for the detection of skeletal metastases. Whole-body MRI is becoming more widely available; it enables the most sensitive detection of bone-marrow metastases and extraosseous tumor extension.

Can osteosarcoma be cured without surgery?

Surgery is an integral part of treatment for patients with localized osteosarcoma as well as select patients with metastatic or recurrent osteosarcoma. Treatment of osteosarcoma without surgery results in significantly lower cure, tumor-free survival, and overall survival rates.

How do you know if osteosarcoma has spread?

A CT scan of the chest may be done to see if cancer has spread to the lungs. Bone scan: A bone scan can help show if a cancer has spread to other bones. This test is useful because it can show all of the bones in the body at once.

What cancers are detected by blood tests?

What types of blood tests can help detect cancer?
  • Prostate-specific antigen (PSA) for prostate cancer.
  • Cancer antigen-125 (CA-125) for ovarian cancer.
  • Calcitonin for medullary thyroid cancer.
  • Alpha-fetoprotein (AFP) for liver cancer and testicular cancer.

Can ultrasound detect bone tumors?

Ultrasound images are not as detailed as those from CT or MRI scans. Ultrasound cannot tell whether a tumor is cancer. Its use is also limited in some parts of the body because the sound waves can’t go through air (such as in the lungs) or through bone.

What are radiological features of osteosarcoma?

The characteristic radiological features are sun-burst appearance, periosteal lifting with formation of Codman’s triangle [Figure 2], new bone formation in the soft tissues along with permeative pattern of destruction of bone and other features for specific types of osteosarcoma.

What is high grade osteosarcoma?

High grade: Most osteosarcomas are high grade, meaning they will probably grow and spread quickly if not treated. The usual treatment for these cancers is as follows: Biopsy to establish the diagnosis. Chemotherapy (chemo), usually for about 10 weeks.

How long does it take for osteosarcoma to metastasize?

The median time for LM was 5-6 months after starting treatment, for EPM 9-10. months. First metastases after 24 months were infrequent, especially in children. With delay in the appearance of metastases, whether LM or EPM, post-metastatic survival lengthened.

How fast does osteosarcoma grow?

The vast majority of osteosarcomas are so-called “random cases”, where no specific causes or predisposing risk factors can be identified. In young people, the development of the tumour appears to be in some way related to periods in life with rapid bone growth, hence the average for tumour development is 14-16 years.

Do benign tumors eat bone?

Noncancerous bone tumors are benign, which means they are not cancer and in general never or rarely spread to other areas of the body. However, they can cause problems because they may weaken bones, interfere with joint movement, or destroy nearby healthy tissue.
