First line therapy with paclitaxel (Taxol) and pegylated liposomal doxorubicin (Caelyx) in patients with metastatic breast cancer: a multicentre phase II study.
The aim of this multicentric phase II study was to investigate the efficacy and toxicity of a combination of chemotherapy containing paclitaxel (Taxol) and a novel compound, a liposomal encapsulated doxorubicin (Caelyx), as first line therapy for patients with metastatic breast cancer. Thirty-four patients with advanced breast cancer were treated with a combination of paclitaxel 175 mg/m2 and liposomal doxorubicin 30 mg/m2, every 3 weeks. The combination chemotherapy was effective in 73% of the patients (ITT) (95% CI 55-86%) (7 complete and 18 partial responses). Grade 3/4 toxicities were documented in a small number of patients. Two toxic deaths (6%) were documented, one a hepatorenal failure and another a febrile neutropenia. One patient experienced pulmonary embolism but continued on treatment after appropriate therapy. The combination of paclitaxel and liposomal encapsulated doxorubicin induces a high and durable response rate with a moderate toxicity profile.
