Etiology of Giant Cell Tumor of Bone

Giant cell tumor of bone is caused by disturbances in the regulation of cell growth and differentiation of osteoclasts. Most cases are associated with mutations in genes that control the cell cycle and proliferation, as well as changes in signaling pathways, including RANK/RANKL/OPG and NF-κB.

  • Genetic mutations: Mutations of genes that control cell growth and proliferation play a key role in the development of giant cell bone tumor.
  • Changes in signaling pathways: Disruptions in signaling pathways such as RANK/RANKL/OPG and NF-κB may contribute to tumor formation.
  • Exposure to external factors: Exposure to harmful substances or radiation on bone tissue cells can cause mutations and lead to tumor development.
  • Bone injuries and fractures: Trauma and damage to the bones can be a provoking factor contributing to the occurrence of giant cell tumor.
  • Inflammatory processes: Chronic inflammation can promote the activation of osteoclasts and increase the risk of developing bone tumors.

The clinical picture of Giant Cell Bone Tumor

The clinical picture of giant cell bone tumor varies depending on the location of the tumor and its size. Patients often complain of pain or discomfort in the affected bone area, which may increase with physical activity. Symptoms may also include swelling, limited mobility, a feeling of heaviness in the limb, and sometimes protrusions of tissue or bone fragments.

Additional signs may include sensory disturbances, muscle weakness, and loss of limb function. In case of complications such as a fracture or bone displacement, acute pain, bone deformity, and other specific clinical manifestations may occur, requiring immediate intervention.

  • Pain and discomfort: Patients usually complain of pain in the area of the affected bone, which may increase with physical activity.
  • Swelling: There may be swelling around the tumor, which can also be accompanied by a feeling of heaviness in the limb.
  • Limited mobility: Patients may experience difficulties with the mobility of the affected limb due to the bone lesion.
  • Bone deformation: In some cases, the tumor may cause deformation of the bone and change its shape.
  • Sensitivity impairment: The development of the tumor may result in sensitivity disturbances in the area of the affected bone and surrounding tissues.
