Background: We hypothesized that a response to pegylated liposomal doxorubicin (PLD, Caelyx/Doxil) followed by maintenance is beneficial and safe in recurrent ovarian cancer.
Patients and methods: Sixteen patients have received PLD for more than 1 year for recurrent ovarian (14) or fallopian tube (2) cancer. All had stable disease or better responses to PLD + carboplatin (5) or topotecan (9) doublets or to PLD alone (2). PLD maintenance therapy 3040 mg/m2 was given every 48 weeks. This analysis focuses on cardiac status, overall tolerance, and time to recurrence.
Results: Termination of PLD was due to progression in all patients. Noteworthy was the lack of cumulative myelosuppression and, with one exception, clinical cardiac toxicity. This patient was hospitalized with cardiogenic shock and fever complicating grade 4 pancytopenia from topotecan ten months after discontinuation of PLD. Seven patients continue to receive PLD after a median of 1680 mg/m2 (11802460 mg/m2). Four of these had documented relapses after 36 years on maintenance occurring in the setting of lengthening of the treatment interval. Maintenance PLD was reinstituted after reinduction with a platinum.
Conclusions: PLD appears to be safe as long-term maintenance in ovarian cancer and may be important for a continued response.
