PURPOSE: To determine whether pegylated liposomal doxorubicin (PLD) has antitumor activity in pretreated patients with persistent or recurrent endometrial carcinoma and to define the nature and degree of toxicity of PLD. PATIENTS AND METHODS: Women with histologically documented recurrent or persistent measurable endometrial carcinoma and with failure of one prior treatment regardless of prior anthracycline therapy were enrolled. PLD was administered intravenously over a 1-hour period at a dose of 50 mg/m2 every 4 weeks; the dosage was modified in accordance with observed toxicity. RESULTS: Of 46 patients entered, 42 were assessable for response, as three were declared ineligible on central pathology review and one was not assessable for response. Forty had received prior chemotherapy, 11 hormonal therapy, and 29 radiation therapy. Doxorubicin had been given to 32 patients, carboplatin with paclitaxel to six, carboplatin to one, and fluorouracil to one. Four patients had partial responses lasting 1.1, 2.1, 3.3, and 5.4 months; the overall response rate was 9.5% (95% confidence interval, 2.7% to 22.6%). Three of these responses (in liver and in lymph node) occurred in patients who had progressed after doxorubicin with either paclitaxel or cisplatin. The median number of courses was 2.5 (range, one to 14). Toxicity was generally mild: only 25 patients experienced leukopenia, with a median WBC count of 2,900 (range, 800 to 3,900) at nadir. The only grade 4 toxicities were one episode each of esophagitis, hematuria, and vomiting. The median overall survival was 8.2 months. CONCLUSION: PLD has only limited activity in pretreated advanced, recurrent endometrial cancer, but further trials in anthracycline-naive patients and in previously untreated patients are ongoing. Its toxicity profile should permit its use in combination with myelosuppressive drugs.
