Differences among young adults, adults and elderly chronic myeloid leukemia patients
2014
Abstract BACKGROUND: The incidence of chronic myeloid leukemia (CML) increases with age, but it is unclear how the characteristics of the disease vary with age. In children, where CML is very rare, it presents with more aggressive features, including huge splenomegaly, higher cell count and higher blast cell percentage. PATIENTS AND METHODS: To investigate if after childhood the disease maintains or loses these characteristics of aggressiveness, we analyzed 2784 adult patients, at least 18 years old, registered by GIMEMA CML WP over a 40-year period. RESULTS: Young adults (YAs: 18-29 years old) significantly differed from adults (30-59 years old) and elderly patients (at least 60 years old)…
A Retrospective Analysis about Frequency of Monitoring in Italian Chronic Myeloid Leukemia Patients after Discontinuation
2019
Background: Successful tyrosine-kinase inhibitors (TKIs) discontinuation has been obtained in some patients (pts) with chronic-phase chronic myeloid leukemia (CP-CML). Careful molecular monitoring after discontinuation is the key to guarantee the safety, in terms of prompt resumption of therapy according to retreatment threshold criteria. It was observed that the majority of relapses usually occur during the first 6 months after TKI discontinuation [Saussele S, Lancet Oncol 2018; Etienne G, JCO 2017], accounting for the monthly quantitative PCR (qPCR) that all prospective protocols included in the trial design at least during the first half-year. Two studies [Kong HJ, Cancer 2017; Shanmugan…
A Retrospective Analysis about Frequency of Monitoring in Italian Chronic Myeloid Leukemia Patients after Discontinuation.
2020
Successful discontinuation of tyrosine kinase inhibitors has been achieved in patients with chronic-phase chronic myeloid leukemia (CML). Careful molecular monitoring after discontinuation warrants safe and prompt resumption of therapy. We retrospectively evaluated how molecular monitoring has been conducted in Italy in a cohort of patients who discontinued tyrosine kinase inhibitor (TKI) treatment per clinical practice. The outcome of these patients has recently been reported&mdash
High BCR-ABL/GUSIS Levels At Diagnosis Are Associated With Unfavorable Responses To Imatinib
2013
Abstract The approval of three tyrosine kinase inhibitors (TKIs) for the first line treatment of Chronic Myeloid Leukemia (CML) has generated an urgent need for molecular parameters predictive of unfavorable therapeutic outcomes. Recent evidence suggests that failure to achieve early molecular responses (i.e. BCR-ABL/ABLIS levels <10% after 3 months or <1% after 6 months of TKI treatment) results in inferior rates of both overall and progression-free survival. With the current study, we wanted to establish if high BCR-ABL transcripts at diagnosis would be associated with unfavorable responses to Imatinib Mesylate (IM). Thus, we correlated quantitative determinations of BCR-ABL levels …
Observational study of chronic myeloid leukemia Italian patients who discontinued tyrosine kinase inhibitors in clinical practice.
2018
It is judged safe to discontinue treatment with tyrosine kinase inhibitors (TKI) for chronic myeloid leukemia (CML) in experimental trials on treatment-free remission (TFR). We collected a total of 293 Italian patients with chronic phase CML who discontinued TKI in deep molecular response. Seventy-two percent of patients were on treatment with imatinib, and 28% with second generation TKI at the time of discontinuation. Median duration of treatment with the last TKI was 77 months [Interquartile Range (IQR) 54;111], median duration of deep molecular response was 46 months (IQR 31;74). Duration of treatment with TKI and duration of deep molecular response were shorter with second generation TK…
Flow Cytometric Immunobead Assay for Detection of BCR-ABL1 Fusion Proteins in Chronic Myleoid Leukemia: Comparison with FISH and PCR Techniques
2015
Chronic Myeloid Leukemia (CML) is characterized by a balanced translocation juxtaposing the Abelson (ABL) and breakpoint cluster region (BCR) genes. The resulting BCR-ABL1 oncogene leads to increased proliferation and survival of leukemic cells. Successful treatment of CML has been accompanied by steady improvements in our capacity to accurately and sensitively monitor therapy response. Currently, measurement of BCR-ABL1 mRNA transcript levels by real-time quantitative PCR (RQ-PCR) defines critical response endpoints. An antibody-based technique for BCR-ABL1 protein recognition could be an attractive alternative to RQ-PCR. To date, there have been no studies evaluating whether flow-cytometr…
High BCR-ABL Levels At Diagnosis Are Associated with Unfavorable Responses to Imatinib Mesylate.
2012
Abstract Abstract 2790 The approval of second-generation tyrosine kinase inhibitors (TKIs) for the first line treatment of Chronic Myeloid Leukemia (CML) has generated a need for early molecular parameters associated with inadequate responses to Imatinib Mesylate (IM). Recent evidence suggests that CML patients presenting BCR-ABL/ABLIS levels >10% after 3 months of IM or >1% after 6 months of treatment have inferior outcomes in terms of both overall survival (OS) and progression-free survival. We wanted to establish if high BCR-ABL transcripts at diagnosis would also be associated with unfavorable responses to IM. To this end, we correlated quantitative determinations of BCR-ABL measu…
