Giant cell tumor of bone (osteoblastoclastoma): treatment, prognosis
How to diagnose and remove osteoblastoclastoma?
Bone tumors often occur unexpectedly for the patient.
The reasons can be injuries or fractures, but in most cases, experts can’t give an exact prerequisites, which could have presented troubles.
Depending on the substances that triggered the appearance of growth, there are benign and malignant tumors of bone.
The same principle is treatment: some tumors are not affected during the whole life, if not bring harm to the human body, while others are subject to immediate removal.
Giant cell tumor of bone almost immediately after detection is removed surgically. In some cases, the tumor is subjected to removal together with a limb.
The concept and stats
Giant cell tumor of bone (has an official name – osteoblastoclastoma) is a benign bone tumor consisting of clusters of layers of mononuclear cells ovoid shape and osteoclastogenic giant multinucleated cells.
Presents disease is approximately 20% of all cases of the formation of bone cancer.
Giant cell tumor of bone began to study more in the 19th century, although it was known about in ancient times. Until recently, this neoplasm was considered a disease of young people, in most cases, boys.
But recent statistics showed that the growths occur in people 15 to 30 years.

To date, the exact cause symptoms tumors is not established. Some estimated factors is still faced disputes among scientists.
The experts agreed on the opinion that the formation of giant cell tumor can be affected by the following factors:
- inflammation of bones and periosteum;
- injuries and bruises, which were obtained repeatedly in one place;
- injuries can also «translate» the existing benign tumor to malignant status;
- on «go» sometimes is affected by the onset of pregnancy in women.
Of course, when the diagnosis of a tumor of the bone causes such illness fade into the background. But people that fall into the risk group according to the above list, you must be careful and attentive.
The symptoms described tumors include:
- pain in the affected area, which is manifested by movement or palpation;
- over the affected area is observed cutaneous vascular pattern;
- in the process of increasing the patient notices the deformity of the affected region, which on palpation gives a painful punishment;
- there is a violation of the functions adjacent to the affected area of the joint or entire limb;
- palpation of tumors cause not only pain, but also a characteristic crunch.
Doctors should be treated at the first signs of the listed symptoms.
Osteoblastoclastoma diagnosis starts with a General inspection specialist.
Then the patient passes a series of examinations, the beginning of which is due to donation of blood for the detection of inflammation and other characteristic changes.
Accurate diagnosis of tumors occurs through the following studies:
- Xray – allows you to quickly determine the nature of the changes of the bone surfaces and sometimes to determine the structure of the tumor.
- CT and MRI – designed to study the depth of the lesion and its composition.
- Biopsy of the tumor is used to identify the composition of the tumor, if experts have any questions. Also often carried out before operational intervention. Is a part of the fence of the tumor for laboratory studies of its composition and structure.
On the basis of diagnostic experts determine the the methodology and treatment plan (if possible).
How to remove a nodule?
Typically, the giant cell tumor itself is not eliminated. So here use only a few ways to remove the affected area:
- Surgery – regional resection of the affected area. Requires recovery of a remote part, as in some cases giant cell tumor of bone is removed along with a bone (sometimes a joint). This decision surgeons and oncologists take to prevent the recurrence of the disease. The restoration of the resulting defect by using a special implant. If a growth is removed from a baby, the implant has a the technical possibilities increase, resulting in the operated child undergoes surgical intervention every 2-3 years.
- Amputation of the extremity is extremely rare. The reason for this removal is the suppuration of the affected area or soft tissues due to the penetration of infection into the body. Sometimes the amputation of a limb carried out in the presence of a tumor of enormous size.
- Radiation therapy – the method is used quite rarely and only in the case of tumors of small size, that is, at the initial stage of disease progression. Under the rays of a tumor reduced in size.
- Radiation exposure – is rarely used and only in cases of «inaccessibility» of the affected area. Leads to many unpleasant consequences in the form of diseases of internal organs. Held course and does not always ensure complete elimination of the tumor.
The method of treatment depends on the disease and other factors that have been identified at the stage of diagnosis.
It should be noted that giant cell tumor has a feature of rapid growth, therefore, the diagnosis and treatment it is necessary to resort immediately.
Complications and prognosis
The complications of the disease can result in delayed treatment or infection.
Also on the complications of already existing tumors affect all of the above reasons the manifestations of the disease.
In view of the complications highlight her transition from benign tumors to malignant and also the formation of metastasis in the internal organs. More vulnerable lungs and other respiratory organs.
So often the operation to remove the tumor can put in the minimal probability of a favorable outcome.
As for predictions, benign giant cell tumor of bone despite its size removes any given treatment.
Relapses occur rarely. They are provoked by the same causes manifestations that led to the formation of the first growths.
If the person is in time to see a doctor, namely at the stage of manifestations of pain with movement or palpation, a favorable outcome is practically 100% probability.
Watch carefully for your condition and at the first signs contact your doctor for diagnosis.
