Research paper on positive results treatment for advanced breast cancer with the fetal estrogen estetrol (E4) has been accepted for publication in the Journal of Cancer Research and Clinical Oncology

Pantarhei Oncology proudly announces that its paper ‘Tumor Suppression, Dose Limiting Toxicity and Wellbeing with the Fetal Estrogen Estetrol (E4) in patients with advanced breast cancer’ has been accepted for publication in the Journal of Cancer Research and Clinical Oncology after comprehensive review. The Journal of Cancer Research and Clinical Oncology is an international peer-reviewed scientific journal in the field of oncology.

The research paper states that treating postmenopausal women diagnosed with advanced breast cancer can be treated safely with high doses of E4. All 12 patients enrolled had progressive, heavily pre-treated advanced breast cancer. No treatment-related serious adverse events  or doses of limiting toxicity (DLTs) occurred during the first 4 weeks of E4 treatment allowing further investigation of all three doses. Five of nine patients completing 12 weeks of E4 treatment showed objective anti-tumor effects and six of nine patients reported improved wellbeing.
