    ABSTRACT: This multicenter phase II trial was conducted to analyze the clinical activity and toxicity of the combination of pegylated liposomal doxorubicin and vinorelbine as first-line treatment in elderly patients with metastatic breast cancer. From August 2002 to August 2004, 42 patients with metastatic breast cancer were recruited for treatment with pegylated liposomal doxorubicin 40 mg/m(2) intravenously (i.v.) on day 1 and vinorelbine 30 mg/m(2) i.v. on days 1 and 15 every 4 weeks. The median age of the patients in this trial was 68 years (range 60-82). 40% of patients had 2 or more sites of metastasis, 33 (78%) had predominantly visceral metastasis, and 7 (16%) mostly bone metastasis. Just 2 (5%) patients had only lymphogenous or soft tissue metastasis. All patients had an ECOG performance status of 0-1, but 70% of the patients had relevant comorbidities. In an intention-to-treat analysis, the overall clinical response rate was 36%, the complete response rate was 2%, and the rate of partial remissions was 34%; stable disease occurred in 30%, and progressive disease was observed in 36%. Median duration of response was 10 months. Median time to progression was 4 months, and median overall survival time was 24 months. The combination of pegylated liposomal doxorubicin and vinorelbine is an active and well tolerated regimen in elderly patients with metastatic breast cancer in first-line treatment.

    ABSTRACT: Fulvestrant (Faslodex) is an oestrogen receptor (ER) antagonist with demonstrated efficacy in patients with advanced and pretreated breast cancer. We present a single-centre experience with fulvestrant administered under the compassionate use programme (CUP) to a total of 54 postmenopausal women with metastatic breast cancer progressing on multiple endocrine and cytotoxic therapies. Patients received 250 mg fulvestrant i.m. once monthly as second- (n = 8), third- (n = 30), fourth- (n = 14) and fifth-line (n = 2) hormonal treatment. The median number of previous endocrine therapies was 2 (range 1-4). Most of the patients also had multiple palliative chemotherapies with a median of 1.7 (range 0-6) prior therapies. The median duration of fulvestrant treatment was 6.3 months (range 1-39 months) and the median duration of follow-up was 19.4 months (range 1-63 months). Objective response was achieved by five patients (9.3%): one complete remission (CR) (1.9%) and four partial remissions (PR) (7.4%). Stable disease (SD) lasting > or =6 months was achieved by 16 patients (29.6%). Thus in all, fulvestrant conferred clinical benefit (CB) on 21 women (38.9%). The median time to progression (TTP) was 6.4 months. In all patients with CR and PR, tumour cells were positive for both ER and progesterone receptor (PgR), but lacked HER2/neu overexpression; one patient with PR had an unknown HER2/neu status. Overall, the drug was well tolerated. No grade 3/4 toxicities were reported. Fulvestrant appears to be an efficient and well-tolerated drug even in women with advanced breast cancer progressing after multiple endocrine and/or cytotoxic treatments.

    ABSTRACT: Aim of this study was to evaluate the clinical benefit and the toxicity of pegylated liposomal doxorubicin. Patients with metastatic breast cancer (n = 30) who failed a prior chemotherapy regimen for metastatic disease received 45 mg/m2 pegylated liposomal doxorubicin (PLD) every 4 weeks following prophylactic administration of metoclopramide (10 mg) and dexamethasone (8 mg). 29 of 30 patients were assessed for clinical benefit and time to progression. All patients were assessed for toxicity and analysis of overall survival. 9 patients (31%) had a partial response, and 16 patients (55%) responded with stable disease, resulting in a clinical benefit rate of 86% (n = 25). Median time to progression was 4 months (95% CI: 2.8-5.2), median duration of response was 7 months (95% CI: 4.7-8.2), and median survival was 12 months (95% CI: 6.7-17.2). Skin toxicity was the most common adverse event (30%, all < or = grade 2). Other toxicities were remarkably low in occurrence. PLD is a well-tolerated, second-line monotherapy with a high rate of clinical benefit.
