Schmitz International Scale (IS)-Standardized BCR-ABL1 Digital Polymerase Chain Reaction (dPCR) Assays Using ABL1, BCR, and GUS Control Genes for Measuring Deep Molecular Response (MR) in Chronic Myeloid Leukemia (CML) BCR-ABL1 tyrosine kinase inhibitors (TKIs) are the standard therapy for Ph-positive CML. Achievement of deep molecular responses (typically defined as ≥4-log reduction in BCR-ABL1 RNA levels) is an emerging treatment goal becoming attainable for more patients due to the availability of second-generation TKIs. BCR-ABL1 IS: BCR-ABL1 measured on the International Scale; CCyR: complete cytogenetic response; ELN: European LeukemiaNet; EMR: early molecular response (BCR-ABL1 IS ≤ 10%); MMR: major molecular response (BCR-ABL1 IS ≤ 0.1%); NCCN: National Comprehensive Cancer Network; Ph +; Philadelphia chromosome-positive; TKI: tyrosine kinase inhibitor. 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-ABL1IS abbreviation stands for BCR-ABL1 ≤ 0.1% On The International Scale. 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 BCR-ABL1 International Scale reporting Serial analysis of BCR-ABL1 mRNA levels by real-time quantitative polymerase chain reaction (QRT-PCR) during and/or after therapy (Imatinib, Dasatinib, Nilotinib, or stem cell transplantation) accurately reflects the level of disease suppression and is an effective method for monitoring treatment efficacy. 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. Since 2006, BCR‐ABL1 IS standardization is propagated along reference laboratories by calculating a laboratory‐specific conversion factor (CF), co‐ordinated in Europe through the European Treatment and Outcome Study project.

CONTEXT: Monitoring BCR-ABL1 expression levels relative to clinically validated response criteria on the International Scale (IS) is vital in the optimal management of patients with chronic myeloid leukemia, yet significant variability remains across laboratories worldwide. 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. 2016-07-01 · Here, we compared the BCR-ABL1 levels determined using international scale (IS)-based commercially available assays.
