Chondrosarcoma is a variety of sarcoma . It is a malignant tumor from the cartilaginous tissue of the skeleton. This malignant formation is the second most common among bone neoplasms. Chondrosarcoma affects mainly the bones of the legs, pelvis, hips, ribs, spine, and shoulder girdle.
Chondrosarcoma manifests itself initially with mild pain, which is then intensified, while in the affected area the swelling increases. Most often, chondrosarcoma affects people from 40 to 60 years, but many cases of diseases in other age groups. Men suffer from chondrosarcoma twice as often as women.
Chondrosarcoma usually develops as a result of malignancy of exostosis or chondroma. The factors predisposing to malignancy are as follows:
The clinical picture and symptoms depend on the degree and type of differentiation of neoplastic cells. Highly differentiated chondrosarcoma develops not immediately - for several years . At first, the patient is troubled for a long time by weak discomfort, then there are small pains in the area of the lesion, which gradually gain intensity and become strong. The pain intensifies at night, weakens after taking an anesthetic drug, after rest does not disappear.
Visually, the tumor can grow to substantial dimensions, deform the surface of the skin. At palpation such a tumor is easily determined. Sometimes the patient is warming the skin over the area of chondrosarcoma and widening the veins under the skin. The last symptoms are not so pronounced in comparison with other malignant tumors of bone tissue. Sometimes the patient complains of the limited movement in the nearby joint.
Low-differentiated forms of chondrosarcoma give a more violent clinical picture. Before the first referral to an orthopedic specialist or traumatologist usually takes no more than three months. The main complaint of the patient is pain, which also worsens at night. Difference of the low-differentiated form of chondrosarcoma from the highly differentiated form in resistance to the action of analgesics. Pain, as a rule, is constant and rapidly growing, the tumor also increases faster than with a more favorable course of the disease.
Treatment of chondrosarcoma
The method of treatment of chondrosarcoma largely depends on the size, location of the tumor, the degree of cancer, the prevalence of the process and the overall well-being of the patient: surgical removal of the tumor, if possible, radiation and chemotherapy. The main methods are radiosurgery and surgery.
