It has been identified by the authors that there are three errors in this paper.

Table 4: Criteria listed under subheading ‘Definitions for measurable disease’ should also include:

‘Bone marrow plasma cells 30%.

Table 5: Bone marrow criteria for CR should be ‘<5% plasma cells’ and not ‘5% plasma cells’.

Table 6: Relapse criteria for progressive disease should state ‘Increase of 25% from lowest response level’ and not ‘Increase of 25% from baseline’.

The authors apologize for these errors.
