Purpose: To explore the activity of pegylated liposomal doxorubicin (PLD) as neoadjuvant therapy of breast cancer.
Methods: The combination of PLD with cisplatin and infusional fluorouracil (CCF) for 8 courses was investigated in patients with primary or recurrent T2-T4a-d N0-3 M0 breast cancer. Patients with ER and/or PgR ≥10% tumors also received letrozole (±triptorelin).
Results: Forty patients entered the study. Four patients had recurrent tumors and 13 had cT4d tumors. Overall, clinical response rate was 77.5% whereas a pathological complete response (pCR) was obtained in 3 patients (7.7%), 4 when considering bilateral tumors. Noticeably 3 pCR were observed among the 10 patients with T4d ER positive tumors (33%). Eleven patients discontinued treatment before completion of the 8 planned courses.
Conclusions: Our results indicated that CCF yielded an appreciable rate of clinical responses in a series of very locally advanced tumors and an unusually high rate of pCR in T4d ER positive tumors, suggesting an enhanced cutaneous activity of PLD.
