Preventing the emergence of osteosarcoma
Refusal of some habits can lead to the prevention of many types of malignant tumors in adults. However, this way to prevent the occurrence of malignant tumors, including osteosarcoma, in children is currently impossible.
Manifestations of osteosarcomas
It must be remembered that the sooner the osteosarcoma is diagnosed, the better the forecast (outcome) of the disease.
Bone pain is the most common complaint of the patient. At first, pain is not constant and usually enhanced at night. In the event of damage to the lower limb, physical exertion leads to an increase in pain and the appearance of chromotype.
Punching in the pain area may appear many weeks later.
Although the osteosarcoma makes the bone less durable, but fractures are rare.
Telangectatic osteosarcomas are a rare tumor variant, but in 30% of cases lead to the fracture of the bone.
Normally at a young age Pain and swelling are frequent phenomenon, so in many cases the osteosarcoma diagnosis is established late.
Osteosarcoma diagnostic methods
Radiography of bones Allows you to determine the osteosarcoma diagnosis, but microscopic confirmation is necessary using a tumor biopsy.
Computed tomography (CT) Along with intravenous contrast, it allows to obtain a detailed bone structure and determine the volume of lesion (nearby muscles, adipose tissue, etc.) and choose a bone biopsy. CT also makes it possible to detect metastases in the lungs.
Through Magnetic resonance tomography (MRI) Soft fabrics, tumors and bone marrow are studied in more detail. In some cases, it is possible to detect small foci of osteosarcoma, which is important for treatment planning. This method is especially valuable when examining the head and spinal cord.
Radionuclide bone scans is carried out using technetium-99. As a result of this study, you can identify the defeat of other bones and pulmonary fabric.
The degree of dissemination of the process
The staging implies the determination of the degree of dissemination of the process
Fundamentally osteosarcomas are divided into localized and metastatic.
With a localized osteosarcommer, only bone and adjacent fabrics are affected, including muscles, tendons and t.D.
In the case of a metastatic osteosarcoma there is a multiple damage to bones, lungs (85%). In addition, it is possible to involve the brain and other internal organs.
In patients with metastases, the forecast is worse than in patients with a localized process. However, in the case of surgical removal of metastases and conducting chemotherapy, the forecast is improved.
