Rapid Profiling of Bone Marrow, at Presentation and After 5 Days of Induction Therapy

2014-07-23 22:00:30 | BioPortfolio

Summary

Personalization of AML therapy, require a reliable mechanism for accurate characterization of patient specific leukemia phenotype and genotype. Patient's specific leukemic phenotype or in practical clinical term, patient's leukemia sensitivity to induction therapy, should best investigated in-vivo during induction. Elimination of circulating leukemic blasts from peripheral blood by day 5 was shown to discriminate between good responders with superior long term survival and poor responders with poor outcome. However, many AML patients have no circulating blasts at diagnosis and even in those who have, elimination rate of it from peripheral blood was never correlated with actual response in bone marrow.

Currently, the only available source for patient's specific leukemia profile, is the bone marrow sample at diagnosis. Since leukemic blasts are heterogeneous and come from multiple different clones, "on diagnosis" marrow consist a spectrum of chemotherapy sensitive and resistance clones. Clones may vary by their molecular abnormalities and results from "on diagnosis" marrow may overlook minor resistant but existing clones. Long term prognosis is determined by those resistant clones and though our interests should be focused into the abnormalities of these clones. Residual blasts on day 5 marrow may better represent the profile of patient's leukemic resistant clones.
