Gemcitabine and cisplatin in metastatic breast cancer

1084 Background: Gemcitabine plus cisplatin have synergistic activity and have been tested in several schedules and doses in metastatic breast cancer. Our objectives were to assesss the efficacy and toxicity of gemcitabine and cisplatin in pretreated patients. Methods: Measurable disease and at least two prior anthracycline and /or taxane-containing regimen in either metastatic or adjuvant setting was required. Treatment consisted of gemcitabine 700mg/m(2) IV infusion over 30 min plus cisplatin 30mg(2) given on day1 and 8 every 3 weeks. Results: Seventy four patients with median age of 48 years (range 26- 73) were recruited. A median of six cycles of the study treatment was delivered. The overal response rate was 30% (95% confidence interval, 12–53%). Median time to progreesion was 30.6 weeks (95%CI, 12.6–44 weeks). Median survival was 73.2 weeks (95% CI, 47.1–93.2 weeks). Toxicities included grade 3 and 4 leukopenia in 27(36.4%), anemia in 19 (25.6%) and oral mucositis in 4 (5.4%). No grade 3 or 4 peripheral neurophaty, hepatic or renal dysfunction was observed. No treatment-related death ocurred. Conclusions: Gemcitabine plus cisplatin is a well tollerated and active treatment in heavily pretreated patients with metastatic breast cancer.

Purpose In this study, two doses of temsirolimus (CCI-779), a novel inhibitor of the mammalian target of rapamycin, were evaluated for efficacy, safety, and pharmacokinetics in patients with locally advanced or metastatic breast cancer who had been heavily pretreated. Patients and Methods Patients (n = 109) were randomly assigned to receive 75 or 250 mg of temsirolimus weekly as a 30-minute intravenous infusion. Patients were evaluated for tumor response, time to tumor progression, adverse events, and pharmacokinetics of temsirolimus. Results Temsirolimus produced an objective response rate of 9.2% (10 partial responses) in the intent-to-treat population. Median time to tumor progression was 12.0 weeks. Efficacy was similar for both dose levels but toxicity was more common with the higher dose level, especially grade 3 or 4 depression (10% of patients at the 250-mg dose level, 0% at the 75-mg dose level). The most common temsirolimus-related adverse events of all grades were mucositis (70%), maculopapular rash (51%), and nausea (43%). The most common, clinically important grade 3 or 4 adverse events were mucositis (9%), leukopenia (7%), hyperglycemia (7%), somnolence (6%), thrombocytopenia (5%), and depression (5%). Conclusion In heavily pretreated patients with locally advanced or metastatic breast cancer, 75 and 250 mg temsirolimus showed antitumor activity and 75 mg temsirolimus showed a generally tolerable safety profile.

PURPOSE: We investigated 96-hour paclitaxel infusion combined with weekly (days eight and 15) vinorelbine as salvage therapy for metastatic breast cancer in anthracycline-exposed patients. All patients received scheduled support with granulocyte colony-stimulating factor (G-CSF; filgrastim). Tumor response, toxicity, time to progression (TTP), and survival were assessed. PATIENTS AND METHODS: This single-center nonrandomized trial enrolled 32 patients. Anthracycline exposure and subsequent progression were common to all patients. Paclitaxel and vinorelbine were escalated over three dosing levels, stratified by liver function. RESULTS: Seven patients (22%) achieved a complete response and nine patients achieved a partial response for an overall response rate of 50%. The median TTP was 6.1 months, and median survival time was 14.1 months. Dose-limiting toxicity was neutropenia, with dose delay or reduction in seven of 32 patients. Febrile neutropenia requiring hospitalization was uncommon (three of 32 patients; 9%). There were no treatment-related deaths. Grade 3/4 thrombocytopenia occurred in two patients (6%), and 13 patients (41%) required RBC transfusions for anemia. Grade 3 nausea and vomiting was seen in one patient, who was found to be Addisonian. Despite potentially overlapping neurologic toxicities of the two agents, only two patients (6%) were removed from the study because of progressive peripheral neuropathy. CONCLUSION: Administration of 96-hour paclitaxel infusion and subsequent weekly vinorelbine with G-CSF support is well tolerated. The response rate, TTP, and survival data are encouraging for therapy given to anthracycline pretreated patients with metastatic breast cancer. If these results can be verified in multi-institution trials, this or a similar combination of drugs would merit investigation as first-line therapy in this patient population.

Purpose Eribulin mesylate (E7389), a nontaxane microtubule dynamics inhibitor, is a structurally simplified, synthetic analog of the marine natural product halichondrin B. This open-label, single-arm, phase II study evaluated efficacy and tolerability of eribulin in heavily pretreated patients with metastatic breast cancer (MBC). Methods MBC patients who were previously treated with an anthracycline and a taxane received eribulin mesylate (1.4 mg/m2) as a 2- to 5-minute intravenous (IV) infusion on days 1, 8, and 15 of a 28-day cycle. Because of neutropenia (at day 15), an alternative regimen of eribulin on days 1 and 8 of a 21-day cycle was administered. The primary end point was overall response rate. Results Of the 103 patients treated, the median number of prior chemotherapy regimens was four (range, one to 11 regimens). In the per-protocol population (n = 87), eribulin achieved an independently reviewed objective response rate (all partial responses [PRs]) of 11.5% (95% CI, 5.7 to 20.1) and a clinical benefit rate (PR plus stable disease ≥ 6 months) of 17.2% (95% CI, 10.0 to 26.8). The median duration of response was 171 days (5.6 months; range, 44 to 363 days), the median progression-free survival was 79 days (2.6 months; range, 1 to 453 days), and the median overall survival was 275 days (9.0 months; range, 15 to 826 days). The most common drug-related grades 3 to 4 toxicities were as follows: neutropenia, 64%; leukopenia, 18%; fatigue, 5%; peripheral neuropathy, 5%; and febrile neutropenia, 4%. Conclusion Eribulin demonstrated activity with manageable tolerability (including infrequent grade 3 and no grade 4 neuropathy) in heavily pretreated patients with MBC when dosed as a short IV infusion on days 1 and 8 of a 21-day cycle.

PURPOSE To provide paclitaxel, an investigational drug at the inception of this study, to women with chemotherapy-refractory metastatic breast cancer and to evaluate response and toxicity in these patients. PATIENTS AND METHODS Two hundred sixty-seven patients with progressive disease (PD) following at least two chemotherapy regimens for metastatic breast cancer and a contraindication to further doxorubicin treatment received paclitaxel either at 175 mg/m2 intravenously (IV) over 24 hours or at 135 mg/m2 if they had prior irradiation to 30% of marrow-bearing bone or a cumulative dose of mitomycin > or = 20 mg/m2. RESULTS In a subgroup of patients (n = 172) with measurable disease, four complete responses (CRs) and 36 partial responses (PRs) occurred, for an overall response rate of 23% (95% confidence interval [CI], 17% to 30%). No differences in response rates were noted according either to the number of prior chemotherapy regimens received or to whether patients were considered refractory to doxorubicin. The dose and schedule used in this trial resulted in febrile neutropenia in 45% of patients and a hospitalization rate of 49%. CONCLUSION Paclitaxel's activity in this multiinstitutional trial in heavily pretreated patients confirms the encouraging results attained in single-institution trials. Although at this dose and schedule paclitaxel may be considered too myelosuppressive for palliative care, supportive measures such as colony-stimulating factors and antibiotics were not used prophylactically. Current research efforts are focusing on whether paclitaxel's activity against breast cancer is dose- and/or schedule-dependent, and on what role it has in patients with less advanced disease.

PurposeTo evaluate trastuzumab (H) and docetaxel (T) with or without capecitabine (X) as first-line combination therapy for human epidermal growth factor receptor 2 (HER2) -positive advanced breast cancer.Patients and MethodsPatients with HER2-positive locally advanced or metastatic breast cancer were randomly assigned to H (8 mg/kg loading; 6 mg/kg every 3 weeks) plus T (75 mg/m2in HTX arm, 100 mg/m2in HT arm, every 3 weeks) with or without X (950 mg/m2twice per day on days 1 to 14 every 3 weeks). The primary end point was overall response rate (ORR).ResultsIn 222 patients, median follow-up was approximately 24 months. ORR was high with both regimens (70.5% with HTX; 72.7% with HT; P = .717); complete response rate was 23.2% with HTX compared with 16.4% with HT. HTX demonstrated significantly longer progression-free survival: median 17.9 months compared with 12.8 months with HT (hazard ratio, 0.72; P = .045), which translates to a gain of around 5 months. Two-year survival probability was 75% with HTX compared with 66% with HT. Febrile neutropenia (27% v 15%) and grade 3/4 neutropenia (77% v 54%) incidences were higher with HT than HTX. Treatment-related grade 3 hand-foot syndrome (17% v < 1%) and grade 3/4 diarrhea (11% v 4%) occurred more commonly with HTX than HT. One case of congestive heart failure occurred in each arm.ConclusionHTX is an effective and feasible first-line therapy for HER2-positive locally advanced or metastatic breast cancer, although it should be reserved for patients with good performance status who are not receiving long-term steroids.
