For conventional doxorubicin, achieving a concentration as high as 10,000 ng/g in the tumor microenvironment is generally not reported. The values in the 10,000 ng/g range are typically associated with specialized formulations or localized delivery methods, such as drug-eluting beads used in transcatheter arterial chemoembolization (TACE) for liver cancer, rather than with conventional systemic administration.
In conventional intravenous administration, the concentration of doxorubicin in tumor tissues usually falls within the 80 to 500 ng/g range, depending on various factors such as the tumor type, dose, and pharmacokinetic properties (AACR Journals) (AACR Journals).
If you need a reference specifically showing a concentration of 10,000 ng/g or more for conventional doxorubicin, it would not align with standard pharmacokinetic data for this method of delivery. The high concentration values are primarily associated with localized and controlled release systems, not with standard IV dosing.
