The Clinical Utility Of Liposomal Doxorubicin In Recurrent Ovarian Cancer.
Published 2001 · Medicine
OBJECTIVES The aim of this study was to determine the efficacy and toxicity of single agent off-protocol, liposomal doxorubicin (Doxil Alza), in consecutive patients with recurrent ovarian cancer and to investigate the influence of HER-2/neu expression on response to liposomal doxorubicin. PATIENTS AND METHODS Retrospective analysis of 72 consecutive patients treated, typically with liposomal doxorubicin 40 mg/m(2) q28 days between January 1997 and December 1998. Results. Twenty-nine patients (40%) had platinum- and taxane-resistant tumors. Nineteen patients (27%) responded with clinical or radiological evidence of response with reduction in CA-125 of >50%. One complete response (CR) and 7 partial responses (PRs) occurred in platinum- and taxane-resistant patients (radiological response (RR) 29%) and 8 PRs occurred in patients with visceral metastases (RR 28%). Time to progression was 5.3 (2.1-12.1) months. Only 7 dose delays (3%) and 20 dose reductions (8%) were necessary in 265 cycles of treatment. Hematological toxicity was generally mild with grade (Gr) > or =III neutropenia in 1 (2%), Gr > or =III thrombocytopenia in 1 (1%), and Gr > or =III anemia in 8 patients (11%). One patient (1%) was admitted with fever and neutropenia. Other toxicity was minimal with Gr > or =III mucositis occurring in 3 patients (4%). Gr > or =III cutaneous toxicity was seen in 6 patients (8%). Three patients (4%) had a >10% fall in ejection fraction but there was no unequivocal clinical heart failure. CONCLUSIONS The data suggest that liposomal doxorubicin is an active drug in both taxane- and platinum-sensitive and resistant recurrent ovarian cancer. Liposomal doxorubicin is associated with tolerable toxicity and is particularly well tolerated in patients with multiple prior lines of treatment.
