Neoadjuvant pegylated liposomal doxorubicin in combination with cisplatin and infusional fluoruracil (CCF) with and without endocrine therapy in locally advanced primary or recurrent breast cancer

PurposeTo explore the activity of pegylated liposomal doxorubicin (PLD) as neoadjuvant therapy of breast cancer.MethodsThe 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).ResultsForty 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.ConclusionsOur 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.
