The International Scale (Leukemia 23:1957-1963, 2009) defines MMR as 0.1% relative ratio. Results calibrated in the International Scale are comparable across laboratories. The International Scale is appropriate for monitoring response to TKI therapy in patients diagnosed with CML with the major BCR/ABL breakpoints (p210, e13a2 and e14a2). 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. proposed in 2005 to harmonize quantitative BCR–ABL1 results on an international scale (IS) anchored to the standard baseline level from the IRIS trial (100% IS), with MMR corresponding to 0.1% IS. 3 To facilitate inter-laboratory comparative assessment, an international scale (IS) for BCR-ABL1 was proposed. Methods The laboratory-specific conversion factor (CF) to the IS can be derived from the World Health Organization (WHO) genetic reference panel; however, this material is limited to the manufacturers to produce and calibrate secondary reference reagents.

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).

2016-01-19 · measure BCR-ABL1 to ABL1, expressed as a log molecular reduction (MR value) from a baseline of 100% on the International Scale, in t(9;22) positive CML patients during monitoring of treatment with Tyrosine Kinase Inhibitors (TKIs). for detecting major BCR-ABL1 mRNA on an International Scale Chikashi Yoshida 1*, Hirohisa Nakamae2, Linda Fletcher3, Daisuke Koga4, Takayuki Sogabe 4, Itaru Matsumura5, Yuzuru Kanakura6, Susan Branford3,7,8,9 and Tomoki Naoe10 Abstract Background: Detection and quantitation of BCR-ABL1 transcripts are crucial for managing patients with chronic Establishment of a standardized multiplex assay with the analytical performance required for quantitative measurement of BCR-ABL1 on the international reporting scale.

Huvuduppgiften för denna studie inkluderar analyser av BCR-ABL1 BCR-ABL1 transkriptioner kommer att övervakas enligt International Scale (IS) parallellt.

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.

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).

What does BCR-ABL1IS stand for? 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.
