This report describes the glycosaminoglycans, collagen and elastin--composition of leiomyosarcoma. Studies were performed on leiomyosarcoma removed during surgery. The material was taken from 7 patients. Rearrangement of extracellular matrix in leiomyosarcoma has been found. There was an increase of total collagen content in comparison to control uterus. In both tissues type I collagen was found to be the predominant one. Both tissues, normal and neoplastic contain all known glycosaminoglycans types. Among them heparan sulphate was found to be the most abundant. A slight decrease in the content of this glycosaminoglycan was observed in leiomyosarcoma. A possible role of these alterations in tumour biology is discussed.

D007890 Leiomyosarcoma A sarcoma containing large spindle cells of smooth muscle. Although it rarely occurs in soft tissue, it is common in the viscera. It is the most common soft tissue sarcoma of the gastrointestinal tract and uterus. The median age of patients is 60 years.

D006025 Glycosaminoglycans Heteropolysaccharides which contain an N-acetylated hexosamine in a characteristic repeating disaccharide unit. The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine (see ACETYLGLUCOSAMINE) or N-acetylgalactosamine (see ACETYLGALACTOSAMINE).
