2003 JUL 3 - (NewsRx.com & NewsRx.net) -- Data show that the bone marker N-telopeptide (Ntx) may predict the clinical outcome of patients with bone complications that stem from a variety of different cancers, according to a study presented at the American Society of Clinical Oncology (ASCO) meeting in Chicago, Illinois.
These results demonstrate the potential role the bone marker may have in providing an early warning of potential skeletal complications and need for treatment of bone metastases, providing physicians a powerful tool in patient management. The analysis included data from three major clinical trials evaluating zoledronic acid in more than 3,000 patients who suffer from a broad range of tumor types, such as breast, prostate, lung and other solid tumors and multiple myeloma.
The data from these studies are the most extensive available and present an unprecedented opportunity to analyze the predictive roles of bone markers for subsequent skeletal complications.
Research indicates that many patients with advanced cancers will develop bone metastasis, the spread of cancerous cells from the original tumor to bones. Often, bone is the only site of metastasis in these patients. Complications resulting from bone metastases include, among others, bone pain, pathologic fractures, a need for radiation or surgery to bone, spinal cord compression, and change of antineoplastic therapy to treat bone pain and hypercalcemia.
"Bone metastases and their complications can be severely debilitating for advanced cancer patients with a highly negative ...
