The name of the disease Kaposi derived from the Greek word «sarcos», which literally means "meat." Sarcoma combines a large group of malignant tumors. Sarcoma is a distinctive feature of its non-epithelial origin. The disease originates from the primary connecting cell - derived mesoderm, from which the resulting complex of histological and morphological processes of developing a malignant tumor formation containing cellular elements of the tendons, ligaments, bones, blood vessels, muscles, brain membranes and so on.
Typically, sarcoma occurs in mature age, the majority of patients over twenty-five years. Among all forms of Kaposi tumor occupies more than 15 percent of cases of malignant neoplasms.
The causes of sarcoma usually associated with the oncogenic substances, as well as with an active ionizing radiation, exposure to which causes a rapid growth of unusual, uncharacteristic for the initial type of tissue, cells, referred to as experts or poorly differentiated atypical.
In addition, modern scientists set data on the influence of some pathogenic viruses and certain chemicals. Today, there are definitely a proven fact that, for example, long-term contact with chemicals such as vinyl chloride, is the cause of angiosarcoma of the liver, and oncogenic viruses contribute to the emergence of a particular type of cancer - soft tissue sarcoma.
Types of sarcoma
All existing types of sarcomas (which today there are a little less than one hundred clinical entities, quite distinct species) divided by tumor cell accessories and its histological structure.
A large group of diseases, which bears the common name sarcoma of bone, comprises the following subspecies:
- Sarcoma cell round - neyrosarkomy, Ewing's sarcoma, lymphosarcoma and other bones.
Soft tissue sarcomas are classified into the following clinical and morphological variants:
- Synovial sarcoma;
- Neurogenic sarcoma;
- Myogenic sarcomas and others.
In addition to a separate group of isolated sarcoma complex cellular structure that due to the low degree of differentiation of the cells can not be clearly attributed to one or another form.
Symptoms of Sarcoma
Clinical signs and symptoms of sarcoma, as well as characteristics of the disease depends on the type of the original cell and tissue localization of tumors. For the vast majority of sarcomas typical symptom is the appearance of the tumor, rapidly increasing in size.
At the first sign of bone sarcoma of the disease is the appearance of nocturnal pain in the bones of unexplained etiology. Typically, pain is not relieved by taking painkillers, over time, the pain in the affected bone department continues to grow. Further abnormal growth of tumor tissue begins to capture the surrounding organs, causing secondary symptoms of Kaposi appropriate place and the extent of damage.
Sarcomas also differ in the speed of propagation. For example, parostalnye bone sarcoma progresses very slowly. This type of cancer can exist with little or no external manifestations for a very long time. In contrast, other types of tumors (e.g., rhabdomyosarcoma) tend to be active growth and widespread metastases. Certain types of sarcomas (such as liposarcoma) multiple different nature of primary education, which greatly complicates their diagnosis and timely treatment of Kaposi's appointment.
Prerequisites for the successful treatment of sarcoma of any kind - early diagnosis and integrated therapeutic approach.
Until recently, the only treatment for sarcoma is an operational method, ie. E. Surgical excision of tumor formation. But today, for the treatment of this severe disease effectively used new methods - radiotherapy and modern anticancer drugs.
The potential in the treatment of Kaposi's prognosis can be made, given the combination of many factors, the main of which - the stage of the disease. For early diagnosis of most types of sarcomas can be treated successfully with modern medical methods.
In Germany, the treatment of cancer is performed efficiently using the most modern equipment. Medical center www.krankenhaus.ru organize treatment abroad for skilled professionals.
