PURPOSE AND METHODS The objective of this multicenter study was to compare the therapeutic index of two different doses of paclitaxel given as a 3-hour infusion in patients with metastatic breast cancer (MBC), who had failed to respond to previous chemotherapy. A total of 471 patients with MBC were randomized to receive intravenous paclitaxel at a dose of 175 or 135 mg/m2 every 3 weeks. RESULTS Better treatment results were achieved with high-dose (HD) versus low-dose (LD) paclitaxel: overall response rate, 29% versus 22% (P = .108); complete response (CR) rate, 5% versus 2% (P = .088); median time to disease progression, 4.2 versus 3.0 months (P = .027); and median survival time, 11.7 versus 10.5 months (P = .321). Patients previously exposed or resistant to anthracyclines were as likely to respond as those without such prior exposure. Treatment was well tolerated, as documented by the number of administered treatment courses (median, six v five; range, one 17 v one to 18), the low frequency of dose reductions (14% v 7%, P = .024), and the small number of patients (n = 9 or 4% vn = 5 or 2%) who required treatment discontinuation for adverse reactions. The incidence and severity of neutropenia and peripheral neuropathy were dose-related. After quality-of-life-adjusted time-to-progression analysis, the HD arm (175 mg/m2) retained its advantage over the LD arm (135 mg/m2). CONCLUSION The results of this trial substantiate the activity of paclitaxel in the treatment of MBC. The observed superior efficacy with a dose of 175 mg/m2 over 135 mg/m2 suggests a dose-effect relationship. The clinical activity in anthracycline-resistant patients is particularly noteworthy. Paclitaxel in breast cancer needs further evaluation in large trials that use combination chemotherapy and involve earlier disease stages.

10618 Background: Successful therapeutic regimens in metastatic breast cancer must balance efficacy and tolerability. D and C is an active and commonly used doublet in this setting. D upregulates thymidine phosphorylase and thus potentiates the anti-tumor effects of C. A schedule with split, low-dose D in combination with low dose C could improve the therapeutic index of this regimen without compromising its clinical activity. Methods: Patients with previously untreated her2-neu negative metastatic breast cancer were included. A Simon 2-stage Phase II clinical trial was designed to assess the response rate (primary end-point), and toxicity of docetaxel 25 mg/m2 on days 1 and 8 in combination with capecitabine 750 mg/m2 bid on days 1–14 of a 21-day cycle. RECIST criteria were used for response assessment, which was performed every 2 cycles. Results: Thirty-one women have been enrolled. Median age was 55. Twenty patients had hormone receptor positive disease. Sites of metastasis were as follows: bone, 24 patients; liver, 14; lungs or pleura 14. A total of 189 cycles have been delivered (median: 4 cycles, range 1–33). Grade 3 and 4 toxicities were as follows: peripheral neuropathy, 2 patients; edema, 1 patient; skin, 1 patient. Two women had fever without neutropenia. Another patient had a gastric perforation but recovered without sequela. Twenty-two patients are available for response evaluation. One patient with a single bone metastasis had a complete response after chemotherapy followed by radiation. Partial responses were seen in 10 patients, for an overall response rate of 50% (95% CI, 30 to 70). Four women had stable disease and 7 had progressed at the time of first assessment. With a median follow-up of 15 months (range 1–26), the median time to treatment failure (all patients) was 7 months (range 1–26+). Median survival has not yet been reached. Out of 8 patients older than 65, seven were evaluable and 4 had a partial response. Conclusions: Split, low-dose Docetaxel and low-dose Capecitabine is an effective combination in the first-line treatment of patients with metastatic breast cancer. Toxicity with this schedule was minimal, making it an attractive regimen for further study. [Table: see text]

PURPOSE We investigated the role of high-dose chemotherapy and autologous bone marrow transplantation (ABMT) as the initial systemic treatment in patients with hormone-unresponsive metastatic breast cancer. We studied a regimen involving a split-course schedule using sequential administration of two pairs of alkylating agents separated by 5 days of rest. The rest period was intended to provide time for recovery from the treatment-immediate adverse effects, thereby allowing further dose escalation. PATIENTS AND METHODS The treatment consisted of thiotepa 225 to 300 mg/m2/d (days - 11 to -9), cisplatin 50 to 100 mg/m2/d (days - 11 and -3), and cyclophosphamide 60 mg/kg/d (days - 3 and -2). Dose escalation was performed in the initial 15 patients before reaching dose-limiting toxicities. When feasible, responding patients received posttransplant irradiation to sites of residual or prior bulky disease. Patients with bone marrow or CNS involvement, prior pelvic irradiation, or age greater than 55 years were excluded. RESULTS Thirty-nine patients with measurable or assessable tumor were enrolled: 23 with visceral metastases, 11 with only soft tissue disease, and five with skeletal involvement. Twenty-five patients had received no chemotherapy for metastatic disease before transplantation. The dose-limiting toxicities of this therapy were renal and gastrointestinal. Six patients died from complications: four of a fungal infection and two of hemorrhage. A complete response was achieved in 14 patients (36%), three of whom are free of disease at 79+, 55+, and 40+ months after transplantation. Ten of 25 patients not treated with standard-dose chemotherapy for metastatic disease achieved a complete response (40%). The three patients in continuous remission were in the untreated relapse group. CONCLUSION This single high-dose treatment achieved a relatively high complete response rate in patients with metastatic breast cancer and may have cured some of them. On the other hand, the split-course dose schedule as tested here did not permit significant dose-intensification.

To test the hypothesis of whether high doses of chemotherapy in combination achieve higher response rates and longer durations of response and survival, we treated 33 pre- and perimenopausal patients with good performance status in a prospective trial with escalating doses of fluorouracil, doxorubicin and cyclophosphamide (FAC). Patients were randomly assigned to be treated within a protected environment (laminar air flow room), with prophylactic antibiotics, or in a standard hospital room. Important patient characteristics were equally distributed in the two treatment arms. A major objective response was observed in 27 of the 32 evaluable patients (84%), and 11 (34%) achieved a complete remission (CR). There was no significant difference in overall and complete response rates between the two treatment arms, nor was there a substantial difference in times to progression or survival between the groups treated in or out of the protected environment. Comparison of the results of this study with previously reported programs of FAC chemotherapy in patients with metastatic breast cancer shows that this study achieved higher overall and complete response rates. However, neither the time to progression, nor the survival of responders or the entire patient group was different from our previous experience with standard FAC chemotherapy. When the study was initiated in 1976, the proposed dose escalation represented high-dose chemotherapy. In retrospect, even the "high" doses used in this study represent only a modest increase over standard doses of chemotherapy. Much steeper dose escalations will be needed to evaluate the efficacy of high-dose chemotherapy in breast cancer, as well as the protective value of the protected environment and prophylactic antibiotics in metastatic breast cancer.

122 Background: In recent years many drug combinations have demonstrated clinical activity in heavily pretreated patients (pts) with metastatic breast cancer (MBC). Eribulin (E) in monotherapy has shown a beneficial effect in overall survival (OS) with slight rate of objective responses (OR) and poor effect in progression free survival (PFS). The Eribulin – Carboplatin (Cb) combination has been studied in other types of tumors in a phase Ib with promising results. We initiated an exploratory program with an off-label combination of E – Cb in pts with visceral disease and ECOG < 2. Methods: We retrospectively analyzed pts with MBC previously treated with anthracyclines, taxanes, and Capecitabine. Chemotherapy regimen consisted of E 1.1mg/m2 on days 1 and 8 and Cb AUC: 5 on day 1 every 21 days. Toxicity was assessed according to CTC criteria v 4.0. OR, PFS and OS rates were also evaluated. RECIST criteria were used to appraise radiological response. Results: Treatment was delivered in 10 pts. Median (M) age was 56 (range, 39-65). Pts characteristics were defined as follows: ECOG 0 (1 pt), 1 (6 pts) and 2 (3 pts); histological subtypes: luminal 9 pts and Her-2, 1 pt. M of previous lines was 7 (3-11). M of metastatic localizations were 3 (1-4). M of administered cycles was 6’5 (1-10). Grade 2 toxicity was asthenia 40%, peripheral neuropathy 10% and nausea - vomiting 10%. G 3 anemia and thrombopenia were noted in 20%. G 3-4 neutropenia was observed in 5 pts. Two pts required hospital admission due to febrile neutropenia. OR rate: complete response 10%, partial response 50% and stable disease 40%. Biochemical response rate was 80%. M of follow-up was 11 months, with M PFS and OS of 8 (4-11) and 18 months (4-18) respectively. Conclusions: Eribulin and Carboplatin is feasible, achieving remarkable response and survival rates with an acceptable toxicity profile in heavily pretreated patients with metastatic breast cancer. Preliminary results are promising and encourage us to continue recruiting patients.

Single Treatment

To evaluate the effect of high-dose chemotherapy in the treatment of metastatic breast cancer, we performed a phase II trial of a single treatment with high-dose cyclophosphamide (5,625 mg/m2), cisplatin (165 mg/m2), and carmustine (600 mg/m2), or melphalan (40 mg/m2) and bone marrow support as the initial chemotherapy for metastatic breast cancer. Twenty-two premenopausal patients with estrogen receptor negative, measurable metastatic disease were treated. Twelve of 22 patients (54%) obtained a complete response at a median 18 days. The overall response rate is 73% (complete and partial response). Median duration of response in the patients achieving complete response was 9.0 months with a median duration of survival for complete responders that is currently undefined. Relapse occurred predominantly at sites of pretreatment bulk disease or within areas of previous radiation therapy. Toxicity was frequent and five patients died of therapy-related complications. The results indicate that a single treatment with intensive combination alkylating agents with bone marrow support can produce more rapid and frequent complete responses than conventional chemotherapy when used as initial chemotherapy for metastatic breast cancer, although median disease-free and overall survival is not improved. Three patients (14%) remain in unmaintained remission beyond 16 months.

e12014 Background: Anthracyclines have been considered the challenge of the treatment of metastatic breast cancer. Docetaxel has changed this belief. We conducted a study in previously anthracyclines treated metastatic breast cancer by the regimen docetaxel 75 mg/m2 Day 1 - capecitabine 2500 mg/m2 day split-up over 2 daily doses from Day 1 to Day 14; every 21 Days. Methods: Patients were eligible if they had metastatic breast cancer after an adjuvant setting by anthracyclines. All patients had measurable disease, PS ≤ 2, adequate organ function. Results: From April 2004 to June 2006, 18 patients were enrolled in the study and were evaluated for the toxicity and preliminary responses to the treatment. 100 % of patients had metastatic breast cancer. The sites of metastases were liver in 14 ( 77.7%), lung in 5 (27.7%) and bone in 9 (50%). 11 patients (61.1%) had 1 or 2 metastatic sites, 7 (38.9%) had 3 metastatic sites. All of 18 patients were assessed for toxicity. The main toxicities were as follows: neutropenia grade 3 in 3 patients (16.6 %), anemia grade 2–3 in 2 patients (11.1%), fatigue in 2 patients (11.1%), hand-foot syndrome in 7 patients (38.9%), vomiting-nausea in 4 patients (22.2%), diarrhea in 2 patients (11.1%), liver toxicity in 3 patients (16.6%). The objective response was obtained in 8 patients (44.4%) (Complete response in 3 patients (16.6%), partial response in 5 patients (27.7%). Median response duration was 9 months (range 4 - 17). 7 Patients (38.9%) had stable disease, progression was observed in 3 (16.6%) of patients. Conclusions: In this preliminary analysis, the combination of docetaxel - capecitabine in the treatment of previously anthracyclines treated metastatic breast cancer appears to be an active schedule. It is safe and active, with a manageable toxicity profile and a good clinical activity. No significant financial relationships to disclose.

Purpose To determine whether the addition of intravenous (IV) vinorelbine to epirubicin increased the progression-free survival in first-line treatment of metastatic breast cancer. Patients and Methods A total of 387 patients were randomly assigned to receive IV epirubicin 90 mg/m2 on day 1 and vinorelbine 25 mg/m2 on days 1 and 8, or epirubicin 90 mg/m2 IV on day 1. Both regimens were given every 3 weeks for a maximum of 1 year but discontinued prematurely in the event of progressive disease or severe toxicity. In addition, epirubicin was discontinued at a cumulative dose of 1,000 mg/m2 (950 mg/m2 from June 1999). Prior anthracycline-based adjuvant chemotherapy and prior chemotherapy for metastatic breast cancer was not allowed. Reported results were all based on intent-to-treat analyses. Results Overall response rates to vinorelbine and epirubicin, and epirubicin alone, were 50% and 42%, respectively (P = .15). The complete response rate was significantly superior in the combination arm (17% v 10%; P = .048) as was median duration of progression-free survival (10.1 months v 8.2 months; P = .019). Median survival was similar in the two arms (19.1 months v 18.0 months; P = .50). Leukopenia related complications, stomatitis, and peripheral neuropathy were more common in the combination arm. The incidences of cardiotoxicity and constipation were similar in both arms. Conclusion Addition of vinorelbine to epirubicin conferred a significant advantage in terms of complete response rate and progression-free survival, but not in terms of survival.
