NATURAL ESTROGENIC SUBSTANCE-ESTRONE vs TACE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Estrone binds to and activates estrogen receptors (ERα and ERβ), leading to modulation of gene transcription and subsequent estrogenic effects on target tissues.
TACE (Transcatheter Arterial Chemoembolization) is not a drug but a procedure combining intra-arterial chemotherapy and embolization. Chemotherapeutic agents (e.g., doxorubicin, cisplatin) are delivered directly to tumor-feeding arteries, inducing cytotoxicity, while embolic agents (e.g., lipiodol, microspheres) occlude blood flow, causing ischemia and enhancing drug retention.
0.1 to 0.5 mg intramuscularly 2 to 3 times per week for estrogen replacement therapy
Transarterial chemoembolization (TACE) with doxorubicin: 50-75 mg/m² or up to 150 mg total dose, administered via hepatic artery injection, repeated every 4-6 weeks as tolerated.

Terminal half-life: 24-48 hours (prolonged due to enterohepatic recirculation and tissue distribution).
Variable depending on the drug; for doxorubicin, terminal half-life is 24-36 hours, clinically relevant for systemic toxicity.
Renal: ~50% (as glucuronide and sulfate conjugates), Biliary/Fecal: ~50% (enterohepatic recirculation).
TACE is not a specific drug but a procedure (transarterial chemoembolization). The chemotherapeutic agents used (e.g., doxorubicin, cisplatin, mitomycin C) are typically eliminated via hepatic metabolism and biliary excretion, with renal excretion as a minor route (<10% for doxorubicin).
