Abstract
BACKGROUND The activity of the combination of carboplatin and liposomal doxorubicin was tested in a Phase II study of patients with recurrent cervical carcinoma. METHODS The combination of carboplatin (area under the concentration curve [AUC], 5) and liposomal doxorubicin (Doxil®; starting dose, 40 mg/m2) was administered intravenously every 28 days to 37 patients with recurrent squamous cell cervical carcinoma to determine antitumor activity and toxicity profile. RESULTS Twenty‐nine patients were assessable for response, and 35 patients were assessable for toxicity. The overall response rate was 38%, the median time to response was10 weeks, the median duration of response was 26 weeks, and the median survival was 37 weeks. The main toxic effect was myelosuppression, with Grade 3 and 4 neutropenia in 16 patients, anemia in 12 patients, thrombocytopenia in 11 patients, and neutropenic fever in 3 patients. Four patients had five infusion‐related reactions during the infusion of liposomal doxorubicin, leading to treatment discontinuation in three patients. Grade ≥ 2 nonhematologic toxicity included nausea in 17 patients, emesis in 14 patients, fatigue in 9 patients, mucositis and/or stomatitis in 8 patients, constipation in 6 patients, weight loss in 5 patients, hand‐foot syndrome in 2 patients, and skin reactions in 3 patients. CONCLUSIONS The combination of carboplatin and liposomal doxorubicin has modest activity in patients with recurrent cervical carcinoma. Cancer 2001;92:2327–33. © 2001 American Cancer Society.
