title: Type I and type III collagen metabolites in adult osteosarcoma patients.
abstract: Three biochemical markers of collagen metabolism were measured in 39 osteosarcoma patients. The pretreatment values did not predict outcome, and the markers showed no consistent change upon development of metastases. Both the age of the patients and the multimodality therapy affected the collagen metabolites. These findings emphasise the need for cautious interpretation of tumour-associated markers.
