After pegylated liposomal doxorubicin (PEG-LD) (Doxil) was shown to be active in ovarian tumors, several trials were developed at the University of Southern California to determine its safety and efficacy in a variety of gynecologic and peritoneal malignancies. Completed phase I and phase II trials have found PEG-LD to be safe and effective in the treatment of platinum- and paclitaxel-refractory epithelial ovarian carcinoma. A new phase II trial is currently underway in similarly refractory patients with ovarian and other related cancers and various degrees of pretreatment. In addition, the efficacy of PEG-LD is being explored in combination with paclitaxel (Taxol), with cisplatin, and with hyperthermia. [ONCOLOGY 11(Suppl 11):38-44, 1997]
