Sarcoma

The sarcoma ( from the Greek σάρκωμα, sarcoma to σάρξ, sarx "flesh ", " soft tissue " and om " tumor " ) is a malignant tumor which originates from the supporting tissue and metastasizes early in the blood vessels ( hematogenous spread ).

Together with the malignant tumors of the Deckepithels ( cancer) and diseases of the blood and bone marrow (leukemia and lymphoma) are sarcomas in the group of malignant tumors ( cancer).

Sarcomas are much less common than carcinomas and account for only about 1% of all malignancies in humans from. The exact origin of the sarcoma is the connective and supporting tissues (bone, cartilage and adipose tissue ) or muscle tissue.

Sarcomas are classified according to the current WHO classification in about 100 different entities. These differ according to their ( partial) supposed origin, their molecular genetic changes, their morphology and their biology. However, the exact position of a sarcoma in the appropriate diagnostic group is of great importance for further treatment, since the individual entities have a different big risk for the occurrence of relapses and metastases ( metastases). Sarcomas metastasize predominantly via the blood.
