I asked for the references:
The exact study I referred to is not specified in my previous response. However, there are several studies that have investigated the pharmacokinetics and tissue distribution of doxorubicin, including its concentration in tumors versus plasma.
One frequently referenced study is:
Matsumura, Y., & Maeda, H. (1986). A new concept for macromolecular therapeutics in cancer chemotherapy: mechanism of tumoritropic accumulation of proteins and the antitumor agent smancs. Cancer Research, 46(12 Part 1), 6387-6392.
This seminal paper introduced the concept of the Enhanced Permeability and Retention (EPR) effect, which explains why macromolecules and nanoparticles, such as liposomal doxorubicin, accumulate in tumor tissues more than in normal tissues.
Another relevant study is:
Gabizon, A., Shmeeda, H., & Barenholz, Y. (2003). Pharmacokinetics of pegylated liposomal Doxorubicin: Review of animal and human studies. Clinical Pharmacokinetics, 42(5), 419-436.
This review discusses the distribution of pegylated liposomal doxorubicin (Doxil) in tumors and plasma, highlighting the higher concentration of the drug in tumors compared to plasma.
