Purpose To compare the effectiveness and tolerability of epirubicin and paclitaxel (EP) with epirubicin and cyclophosphamide (EC) as first-line chemotherapy for metastatic breast cancer (MBC). Patients and Methods Patients previously untreated with chemotherapy (except for adjuvant therapy) were randomly assigned to receive either EP (epirubicin 75 mg/m2 and paclitaxel 200 mg/m2) or EC (epirubicin 75 mg/m2 and cyclophosphamide 600 mg/m2) administered intravenously every 3 weeks for a maximum of six cycles. The primary outcome was progression-free survival; secondary outcome measures were overall survival, response rates, and toxicity. Results Between 1996 and 1999, 705 patients (353 EP patients and 352 EC patients) underwent random assignment. Patient characteristics were well matched between the two groups, and 71% of patients received six cycles of treatment. Objective response rates were 65% for the EP group and 55% for the EC group (P = .015). At the time of analysis, 641 patients (91%) had died. Median progression-free survival time was 7.0 months for the EP group and 7.1 months for the EC group (hazard ratio = 1.07; 95% CI, 0.92 to 1.24; P = .41), and median overall survival time was 13 months for the EP group and 14 months for the EC group (hazard ratio = 1.02; 95% CI, 0.87 to 1.19; P = .8). EP patients, compared with EC patients, had more grade 3 and 4 mucositis (6% v 2%, respectively; P = .0006) and grade 3 and 4 neurotoxicity (5% v 1%, respectively; P < .0001). Conclusion In terms of progression-free survival and overall survival, there was no evidence of a difference between EP and EC. The data demonstrate no additional advantage to using EP instead of EC as first-line chemotherapy for MBC in taxane-naïve patients.

Background: We directly compared CTC detection rates and prognostic significance, using three different methods in patients with breast cancer (BC). Methods: Early (n=200) and metastatic (n=164) patients were evaluated before initiating adjuvant or first-line chemotherapy, using the CellSearchTM System, an RT-qPCR for CK-19 mRNA detection and by double immunofluorescence (IF) microscopy using A45-B/B3 and CD45 antibodies. Results: Using the CellSearchTM System, 37% and 16.5% of early BC patients were CTC-positive (at ≥1 and ≥2 CTCs/23 ml of blood), 18.0% by RT-qPCR and 16.9% by IF; no agreement was observed between methods. By the CellSearchTM 34.8% and 53.7% (at≥ 5 and ≥ 2 CTCs/7.5 ml) of metastatic patients were CTC-positive, 37.8% by RT-qPCR and 28.5% by IF. A significant agreement existed only between the CellSearchTM and RT-qPCR. In 60.8% of cases, differential EpCAM and CK-19 expression on CTCs by IF could explain the discrepancies between the CellSearchTM and RT-qPCR. CTC-positivity by either method was associated with decreased overall survival in metastatic patients. Conclusion: A significant concordance was observed between the CellSearchTM and RT-qPCR in metastatic but not in early BC. Discordant results could be explained in part by CTC heterogeneity. CTC detection by all methods evaluated had prognostic relevance in metastatic patients.

1001 Background: Chemotherapy for patients with metastatic breast cancer is not curative. Anthracyclines and taxanes are among the most active drugs. Optimal duration of chemotherapy in women with metastatic breast cancer is an open issue. Should they receive chemotherapy to progression or should chemotherapy be stopped after a fixed number of courses? The excellent safety profile of weekly paclitaxel prompted us to evaluate its role as maintenance treatment in this setting. The primary objective was to determine if addition of maintenance weekly paclitaxel prolongs progression-free survival in women with metastatic breast cancer on first-line chemotherapy. Secondary objectives included overall survival and toxicity. Methods: Following Ethical Committee approval and informed consent, from 2002 to 2006 180 women with metastatic breast cancer and no prior chemotherapy for metastatic disease were randomized 1:1 in the TASMAN phase III trial to: 3 courses of epirubicin 100 mg/m2 day 1 q 21 days, followed by 3 courses of paclitaxel 225 mg/m2 day 1 q 21 days, without further chemotherapy or hormonal therapy until progression (arm A), or 3 courses of epirubicin followed by 3 courses of paclitaxel and then maintenance with paclitaxel 60 mg/m2 day 1 q 7 days until progression or unacceptable toxicity (arm B). Results: Median age: 51 years (range: 30–73). Median performance status (ECOG): 0 (0–2). Sites of metastases: bone (36%), liver (20%), pleura and/or lung (19%), skin and/or lymph nodes (18%). No grade 3–4 toxicities were seen with maintenance chemotherapy. As of January 1, 2009, 18 patients remained progression-free and 48 were alive, with a minimum follow-up of 2 years. Median progression-free survival was 8 months for arm A versus 12 months for arm B (p = 0.1, logrank). Median overall survival was 24 months for each arm (p = 0.7). Conclusions: Maintenance chemotherapy with weekly paclitaxel following first-line chemotherapy with anthracycline and taxane is well tolerated but does not significantly increase progression-free survival. No significant financial relationships to disclose.
