ClinConnect Summary

Plasma concentrations of doxorubicin will be determined and venous blood samples will be obtained from each patient for SNP genotyping of genes involved in doxorubicin transport and metabolism on its pharmacokinetics and toxicity in Egyptian breast cancer patients \[prospective study\].

A complete blood count was carried out at baseline for patients receiving neoadjuvant chemotherapy. The neutrophil to lymphocyte ratio (NLR) was calculated as the ratio between the absolute count of neutrophils and the absolute count of lymphocytes \[ retrospective study\].
