Estramustine, a unique combination of estradiol and nitrogen mustard, presents a multifaceted approach to the treatment of advanced prostate cancer. By incorporating both hormonal and cytotoxic mechanisms of action, estramustine targets prostate cancer cells through multiple pathways, offering distinct benefits in terms of tumor regression and disease control. Estradiol, a form of estrogen, acts as a competitive inhibitor of androgen receptors, disrupting the signaling cascade that promotes prostate cancer cell proliferation. Additionally, estradiol may induce apoptosis in prostate cancer cells and suppress angiogenesis, further inhibiting tumor growth and metastasis. The nitrogen mustard component of estramustine functions as an alkylating agent, causing DNA damage and interfering with DNA replication and cell division, ultimately leading to cell death.

Furthermore, estramustine demonstrates efficacy in both hormone-sensitive and hormone-refractory prostate cancer, offering a therapeutic option for patients at various stages of the disease. Its dual mechanism of action makes it particularly valuable in the management of prostate cancer that has become resistant to standard hormonal therapies, providing an alternative treatment approach to overcome resistance mechanisms and prolong disease control. Moreover, estramustine’s oral formulation enhances patient convenience and compliance compared to intravenous chemotherapy regimens, allowing for outpatient treatment and minimizing the need for frequent clinic visits.
