CAELYX/DOXIL, pegylated liposomal doxorubicin, has shown antitumour activity and reduced toxicity compared with standard doxorubicin in other tumour types. In this prospective randomised trial, 94 eligible patients with advanced soft-tissue sarcoma (STS) were treated, 50 with CAELYX (50 mg/m(2) by a 1 h intravenous (i.v.) infusion every 4 weeks) and 44 with doxorubicin (75 mg/m(2) by an i.v. bolus every 3 weeks). Histological subtypes were evenly matched, 33% were leiomyosarcoma (CAELYX: 18; doxorubicin: 13). Primary disease sites were well matched. CAELYX was significantly less myelosuppressive, only 3 (6%) patients had grade 3 and 4 neutropenia, versus 33 (77%) on doxorubicin; febrile neutropenia occurred in 7 (16%) patients given doxorubicin, but only 1 (2%) given CAELYX. 37 (86%) patients on doxorubicin had grade 2-3 alopecia, but only 3 (6%) on CAELYX, and the major toxicity with CAELYX was to the skin. Palmar-plantar erythrodysesthesia with CAELYX was grade 1: 4 (8%) patients, grade 2: 11 (22%) patients, grade 3: 9 (18%) patients and grade 4: 1 (2%) patient. Other non-haematological grade 3 and 4 toxicities were rare. Confirmed responses were observed with both agents: CAELYX: complete response (CR) 1 (uterine), partial response (PR) 4 (response rate (RR) 10%); and doxorubicin: CR 1, PR 3 (RR of 9%); with the best response being stable disease (NC) in 16 and 18 patients, respectively. The reason for the low response rate is unknown, but it may be due partly to a high proportion of gastrointestinal stromal tumours. In conclusion, CAELYX has equivalent activity to doxorubicin in STS with an improved toxicity profile and should be considered for further investigation in combination with other agents such as ifosfamide.

The aim of this study was to evaluate the safety and efficacy of liposome-encapsulated doxorubicin citrate (LEDC) in patients affected by recurrent/metastatic gynecological malignancies scheduled for palliative chemotherapy. Inclusion criteria were proven recurrent/advanced gynecological neoplasms, measurable/assessable disease, adequate organ function, left ventricular ejection fraction >50% as determined by echocardiography, informed consent. LEDC was administered intravenously over 1 h at the dose of either 75 mg/m(2) or 60 mg/m(2) (every 3 weeks until disease progression or toxicity prohibiting further therapy). From May 2003 to September 2005, 36 patients were enrolled. Primary disease was ovarian, endometrial, and cervical cancers in 15 (42%), 11 (30%), and 10 (28%) patients, respectively. LEDC was employed as third- or fourth-line chemotherapy in 25 (70%) and 11 (30%) patients, respectively. The median number of courses of LEDC received was 3 (range 2-9). Six patients (17%) achieved a partial response to treatment lasting 27 weeks and 10 patients (28%) experienced stable disease lasting 18 weeks. The predominant toxicity was hematological, especially neutropenia. Among patients receiving a dose of 75 mg/m(2), two (11%) suspended therapy for febrile neutropenia, and nine (50%) required a dose reduction of 25%. As a result, the next 18 patients were treated at a reduced dose (60 mg/m(2)) of LEDC. Severe neutropenia (G3-G4) was significantly less common in this group (61% versus 22%; P= 0.04). LEDC has shown antineoplastic activity in previously treated recurrent/metastatic gynecological cancer patients and the toxicity profile could be considered acceptable at a 60 mg/m(2) dosage.
