BCR-ABL1 e13a2 or e14a2 fusion transcripts corresponding to the translocation (9;22) are present in >95% of chronic myeloid leukemia (CML) patients. This molecular signature is thus useful to monitor tumor burden and tyrosine kinase inhibitor treatment response in CML. INTRODUCTION: Standardization of BCR-ABL1 messenger RNA quantification by real-time PCR on the International Scale (IS) is critical for monitoring therapy response in chronic myelogenous leukaemia. BCR-ABL1, t(9;22) Source: 31208-2: 2005012: BCR-ABL1, Major (p210) Result: 42714-6: 2005014: BCR-ABL1, International Scale (Percent) 69380-4: 2005015: EER BCR-ABL1, Major (p210) 11526-1 In this programme participants are provided with lyophilised cell-lines for quantitative BCR-ABL1 analysis. Participants are asked to submit quantitative results, either as %BCR-ABL1/control gene or %BCR-ABL1/control gene on the international scale (IS) together with details of the methodology. 2013-09-01 · Achieving defined levels of BCR-ABL1 on the International Scale within specific time frames is an important measure for assessing patient response and probability for relapse and progression. However, extensive variation in quantitative RT-PCR procedures and reporting makes it difficult to interpret these results.

Clonal distribution of BCR-ABL1 mutations and splice isoforms by single-molecule long-read RNA sequencing.

The IRIS trial established a standard baseline for measurement – (100% BCR-ABL1 on the ‘international scale’) and a major molecular response (good response to therapy) was defined as a 3-log reduction in the amount of BCR-ABL1 – 0.1% BCR-ABL1 on the international scale.

BCR-ABL1 fusion transcripts detected below the limit of quantitation. BCR-ABL1 to ABL1 ratio cannot be calculated.

of BCR-ABL1 transcripts to control gene is less than or equal to 0.1% according to the International Scale (IS), a consensus standardized measurement scale

Unique to the leukemic clone, BCR-ABL1 FG transcripts could serve as both therapeutic and prognostic targets.

Molecular monitoring of chronic myeloid leukemia patients using robust BCR-ABL1 tests standardized to the International Scale (IS) is key to proper disease management, especially when treatment cessation is considered. Most laboratories currently use a time-consuming sample exchange process with reference laboratories for IS calibration.
