Results of a recent Greek study show that high levels of the protein sclerostin in the blood are associated with advanced disease and poor bone formation in multiple myeloma patients.

In addition, the results indicate that Velcade may be effective in reducing sclerostin levels in myeloma patients.

“Our study has shown that sclerostin is increased in myeloma patients, and together with the [laboratory] data presented at the last ASH meeting, suggests that sclerostin inhibits the function of [bone-building cells] in myeloma,” said Dr. Evangelos Terpos of the Alexandra General Hospital…

Multiple myeloma is the most frequent cancer to involve the skeleton, with up to 80 percent of patients having bone disease. Although fewer patients appear to have bone involvement more recently, it is still a major source of both complications and death among patients with myeloma.

Bone disease is so severe in myeloma because the normal bone remodeling process is disrupted. In normal individuals, damaged bone is removed by bone-destroying cells, the osteoclasts, and then bone is replaced by bone-forming cells, the osteoblasts. In myeloma, the number and activity of…

This past Sunday was the third day of the American Society of Clinical Oncology (ASCO) 2011 annual meeting, and it was a particularly busy day for meeting attendees interested in multiple myeloma.

The Beacon published an update yesterday covering two sets of presentations made at Sunday’s oral session about multiple myeloma.  This article covers the other set of presentations, which was about myeloma bone disease, as well as material from an afternoon education session focused on myeloma.

The results from a clinical trial, called the ZMAX trial, suggest that administering Zometa intravenously over a longer period does not increase the drug’s safety compared to shorter infusion times.

Dr. James Berenson, from Berenson Oncology and lead author of the study, stated in email correspondence with The Myeloma Beacon that he hopes these study results will reassure patients that a 15-minute infusion time is safe.  Ultimately, the study authors suggested that infusion duration should be based on individual patient considerations.

Zometa (zoledronic acid) is an intravenous bisphosphonate that reduces…

A group of leading myeloma specialists, known as the International Myeloma Working Group, recently collaborated to develop guidelines for the proper management of bone disease in multiple myeloma. The group recommended that patients with bone disease should be treated with standard dosages of intravenous bisphosphonates. A minimally invasive procedure called kyphoplasty may also be considered to reduce bone pain and improve functional ability.

Dr. David Roodman of the University of Pittsburgh presented these findings at the International Myeloma Workshop (IMW) on May 6 in Paris.
