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. BCR-ABL1 e13a2 or e14a2 fusion transcripts corresponding to the translocation (9;22) are present in >95% of chronic myeloid leukemia (CML) patients.

Although an International Scale (IS) was developed for standardized reporting of BCR-ABL1 RNA levels, IS adoption has been slow in the United States, but is now used by the vast majority of laboratories. 2020-01-01 · Aimed at these problems, many efforts have been made to standardize BCR-ABL1 testing to reduce variation and improve accuracy, such as definition of the standardized baseline [11,12], proposal of the international scale (IS) , establishment of conversion factors (CFs) by sample exchange programs , and development of primary and secondary reference reagents 14, 15, 16, among which the establishment of the World Health Organization (WHO) primary panel was an important milestone in A scale established in 2005 to standardize quantitative BCR-ABL1 measurements across tests and laboratories, so as to facilitate interlaboratory studies, patient portability, and a harmonized definition of treatment response. 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.

If positive, the quantitative level is reported as the normalized ratio of BCR/ABL1 (p210) to endogenous ABL1 mRNA with conversion to a percentage referenced to the international scale (IS), on which 0.1% BCR/ABL1:ABL1 (also represented on a log scale as Molecular Response 3, or MR3) is designated as a major In 2005, standardization of BCR-ABL1 reporting across tests and laboratories was established through a common international scale (IS) anchored to the baseline BCR-ABL1 expression levels of the IRIS study (International Randomized Study of Interferon vs STI571) (4, 5). The International Scale (Leukemia 23:1957-1963, 2009) defines MMR as 0.1% relative ratio.
