Description

The International Scale (IS) was established in 2005 to standardize quantitative BCR-ABL1 measurements across tests and laboratories. (Hughes et al., Blood 2006). The IS is anchored to the baseline BCR-ABL1 expression level from the International Randomized Study of Interferon vs STI571 (IRIS) trial (100% IS) with a major molecular response (MMR) corresponding to 0.1% IS. (Hughes et al., N Engl J Med 2003). The IRIS trial and follow up studies have demonstrated that achieving MMR, or a 3-log reduction in BCR-ABL1 expression from the standardized baseline level, is a key clinical outcome. Percent ratios on the IS are obtained by multiplying the percent ratio (100 x BCR-ABL1/control gene) determined at local labs by a test-specific conversion factor (IS % ratio = local % ratio x conversion factor).
