Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The combined pharmacogenetic score was strongly correlated with the original Cmin (r= -0.748; p = 0.002) and was the only independent predictor of initial Cmin (after adjusting the dose and the route of administration). In addition, none of the patients having a genetic score \<2 (ie metabolizing capacity of reduced VRC) did not show an initial Cmin below 1 mg/L, while the initial Cmin was below this threshold efficiency in 47% of patients with a genetic score \>2. The aim of this new study is to confirm the impact of the pharmacogenetic score on the initial VRC Cmin over a larger prospective cohort of 60 adult patients with onco-hematological diseases.
