Prolonged Protection From Bone Disease in Multiple Myeloma

Brief description of study

Main hypothesis: Patients who continue zoledronic acid after year 2 have longer time until progression in bone disease compared to patients who stop treatment after two years?

Secondary hypothesis: Serum will bone markers increase prior to progression in bone disease in the individual patient?

Secondary hypothesis: Low-dose CT will detect more cases of osteolytic bone disease in Multiple Myeloma compared to conventional radiography

Detailed Study Description

Newly diagnosed myeloma patients will be followed for 4 years. The first two years they will be treated with zoledronic acid monthly. At year 2 they will be randomized to A continue treatment for 2 more years or B stop treatment. The primary outcome of the study will be time to progressive bone disease from year 2 and onward.

Serum bone markers will be measured throughout the study. In patients who experience progressive bone disease, development of bone markers prior to the radiological progression will be investigated to see the if it could have been predicted with the use of serum markers

During the four year period patients will have low-dose CT superior and conventional radiography made at predefined time points. The secondary outcome of the study is to compare the sensitivity of the two modalities
