Abstract
PURPOSE Vinorelbine-trastuzumab combination proved to be an effective first-line treatment for patients with locally advanced or metastatic breast cancer (MBC). Oral chemotherapy represents a step forward in MBC management. To improve patients' comfort using the oral form of vinorelbine, we conducted a multicenter phase II study to investigate the efficacy and safety of the oral vinorelbine-trastuzumab combination in women with MBC with human epidermal growth factor receptor 2 (HER2) overexpression. METHODS Main eligibility criteria: HER2-positive disease, no adjuvant chemotherapy within the last 6 months and no prior chemotherapy for MBC. Patients were treated with oral vinorelbine 80 mg/m(2) D1, D8, D15 (following first 3 administrations at 60 mg/m(2) during the first cycle) for a total of 8 cycles (1 cycle = 3 weeks), in combination with trastuzumab 6 mg/kg on D1 (loading dose: 8 mg/kg) every 3 weeks or 4 mg/kg (loading dose: 6 mg/kg) weekly. Response was evaluated every 2 cycles using RECIST 1.0. PRIMARY ENDPOINT objective response rate (ORR); secondary endpoints: duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety. RESULTS In the full population (n = 26), median age was 50.7 years and median WHO PS 0. Median disease-free interval was 50.7 months [95 % CI (43.6-57.9)]. In the evaluable patients population, ORR was 56 % [95 % CI (34.9-75.6)], including 3 complete responses (12 %) and 11 partial (44 %); 8 (32 %) patients had stable disease resulting in a clinical benefit (or disease control) rate of 88 % [95 % CI (68.8-97.5)]. Median DOR was 7.1 months [95 % CI (3.9-10.2)], median PFS 6.7 months (95 % CI 3.5-10), and median OS 27.9 months (95 % CI 17.4-38.3). Treatment was generally well tolerated with main observed grade 3/4 hematological toxicities being neutropenia (46 %) and anemia (4 %). Grade 3-4 nausea-vomiting were observed in 11.5 % of patients. CONCLUSIONS Our results confirm the efficacy of oral vinorelbine-trastuzumab combination as a first-line treatment in HER2-positive locally advanced or MBC patients with an acceptable safety profile. Oral vinorelbine-trastuzumab optimizes the convenience of this chemotherapy regimen, especially for patients receiving trastuzumab every 3 weeks.

Abstract
No standard chemotherapy has been defined for metastatic breast cancer (MBC) patients pretreated with anthracyclines and taxanes. A multicenter phase 2 study was conducted to evaluate the safety and efficacy of oral etoposide in patients with MBC.Eligible patients were treated with repeated cycles of oral etoposide (60 mg/m/d on days 1-10, followed by 11 days of rest). The primary endpoint was progression-free survival (PFS). The secondary endpoints were objective response rate, clinical benefit rate (CBR), and toxicity profiles.Seventy-five women with MBC were enrolled at 10 centers in China. Seven (9.3%) patients achieved partial response (PR) and 29 (38.7%) had stable disease (SD). Nine patients (12%) had SD for >24 weeks and the CBR was 21.3% (16/75). The median PFS was 4.5 (range, 1.3-7.7) months. Of the 38 patients who received ≥3 regimens prior to this study, 2 (5.3%) had PR and 3 (7.9%) had SD for >24 weeks, with a CBR of 13.2%. The reported grade 3/4 adverse events included leukopenia (13.3%, n = 10), neutropenia (17.9%, n = 14), anemia (2.7%, n = 2), vomiting (2.6%, n = 2), and alopecia (1.3%, n = 1).Oral etoposide was effective and well tolerated in Chinese women with pretreated MBC.

Abstract
BACKGROUND Docetaxel and vinorelbine have demonstrated efficacy in the treatment of metastatic breast cancer (MBC). This prospective feasibility study compared the efficacy of these two treatments in MBC. METHODS Patients with MBC progressing following anthracycline treatment were randomly assigned to either docetaxel (100 mg/m(2)day 1 q3W) or vinorelbine (25mg/m(2) day 1 q2W). Patients were eligible to cross over at progression. Objective response rates (ORR), time to progression (TTP) and overall survival (OS) were measured. RESULTS 37 patients were randomised. 2 patients were excluded due to protocol violations. Of 35 remaining patients 17 received docetaxel and 18 received vinorelbine per protocol. ORR was 12.5% and 6.0% respectively for docetaxel and vinorelbine. The median time to progression was 10.4 weeks (range 6-14 weeks) in docetaxel arm and 7.6 weeks (range 4-11 weeks) in vinorelbine arm (p = .82). The clinical benefit rate (defined as complete response, partial response plus stable disease) was 44% in the docetaxel arm and 12% in the vinorelbine arm. Based on intent to treat the median OS in the docetaxel arm was 34 weeks (95% CI, 20.7-48) and 21.2 weeks (95% CI, 17-25.4) in vinorelbine arm (p = .388). 16 patients crossed over, 5 from docetaxel to vinorelbine and 11 from vinorelbine to docetaxel. At cross over the ORR was 0% and 18% on cross over to vinorelbine and docetaxel respectively with a median TTP of 17.3 weeks (95% CI, 16.3-18.1) and 18.7 weeks (95% CI, 13.9-23.4) for those receiving vinorebine and docetaxel at cross over respectively. Vinorelbine however was much better tolerated with fewer grade 3-4 toxicity events (n = 4) than docetaxel (n = 27). DISCUSSION While docetaxel resulted in a longer TTP and OS in this study it did not reach statistical significance. TTP duration for those patients who crossed over was similar, but overwhelmingly vinorelbine had fewer significant grade 3-4 toxicities than docetaxel. Only two previous randomized studies have compared the efficacy of single agent docetaxel and vinorelbine following prior anthracycline exposure, one in an unselected population [16], and the other, HERNATA, in HER2 positive disease with trastuzumab used in both arms [17]. The patients randomized in this study were relatively heavily pretreated with the majority having received 2-3 lines of prior treatment for their metastatic disease. The lower response rates with vinorelbine as compared to docetaxel in this study concur with results reported in other studies [16]. However, the numbers in both this study and the other unselected study [16] are small and need to be interpreted with caution. With regard to toxicity, in the present study, grade 3-4 hematological adverse events and infection were tenfold greater with docetaxel as compared with vinorelbine, consistent with results in HERNATA [17]. While others have reported a significantly higher number of overall grade 3-4 toxicities with vinorelbine [16], the fact that, as in HERNATA, discontinuations due to toxicities in that study [16] were significantly greater with docetaxel as compared to vinorelbine suggests either the toxicity data collected did not reflect the true toxicities on treatment or that docetaxel toxicities were in some way more severe or protracted leading to more numerous discontinuations [16]. Larger randomized studies are needed to determine (1) the efficacy of docetaxel versus vinorelbine in anthracycline pretreated disease and (2) the efficacy of vinorelbine after prior taxane exposure, and particularly how it may compares both with regard to efficacy and tolerability with other possible regimens that may utilized such as carboplatin-gemcitabine [20] or eribulin [21]. The longer as well as comparable TTP at cross over for both agents compared to that upfront suggests there may be enrichment at cross over of a group of patients who are not only fit for further treatment but are more likely to a derive continued benefit from additional treatment.

Abstract
BACKGROUND To evaluate the efficacy and safety of oral and i.v. vinorelbine plus trastuzumab as first-line regimen in a patient-convenient application for human epidermal growth factor receptor 2 (HER2)-overexpressing patients with metastatic breast cancer. PATIENTS AND METHODS Forty-two women were enrolled in a multicenter study. The patients received i.v. vinorelbine at a dose of 25 mg/m(2) on day 1 followed by oral vinorelbine at a dose of 60 mg/m(2) on days 8 and 15 in a 3-week cycle. Standard dose trastuzumab was given at 3-week intervals. RESULTS Complete response was observed in 7 patients (18.9%) and partial response in 19 patients (51.4%), for an overall response rate of 70.3% [95% confidence interval (CI) 53.0-84.1]. The disease control rate reached 91.9% (95% CI 78.1-98.3). The median time to progression was 9.3 months, while median overall survival reached 35.6 months. Hematological and non-hematological toxic effects were acceptable with grade 3-4 leukopenia of 14% and neutropenia of 38%; cardiac toxicity did not reach the level of clinical relevance. CONCLUSION The combination of i.v. and oral vinorelbine plus trastuzumab demonstrates high activity and good tolerability in first-line treatment of HER2-overexpressing metastatic breast cancer. In addition, it offers convenience for the patients with only one i.v. treatment every 3 weeks.

Abstract
Trastuzumab has shown activity in early breast cancer patients that overexpress HER2. Significant resources have to be allocated to finance this therapy, underlining the need for cost-effectiveness analysis. A model was set up, societal costs were calculated and the discount rate was 3%. Life expectancy data were based on the literature and prolonged according to qualified guess (10% and 20% absolute improvement in overall survival (OS)). The comparator was the FEC(100) regimen. The median additional health care cost per patient treated was 33,597 euros. The yielding cost per life year gained (LYG) was 15,341 euros with a 20% improved OS and 35,947 euros with 10% improved OS. The corresponding net health care cost per quality adjusted life year (QALY) was 19,176 euros and 44,934 euros. Including all resource use the figures were 8148 euros and 30,290 euros per LYG. Sensitivity analyses documented survival gain, price of trastuzumab, production gain and discount rate to be the major factors influencing cost-effectiveness ratio. Trastuzumab is indicated cost effective in Norway.

Abstract
BACKGROUND It is not clear what the optimal treatment of chemotherapy is for patients with heavily treated metastatic breast cancer (MBC). We have retrospectively examined the efficacy and safety of S-1 in patients with MBC who had been previously treated with anthracycline, taxane, and capecitabine. METHODS Patients with MBC who had been administered S-1, an oral modulated compound containing a fluoropyrimidine derivative, between November 2001 and June 2003 at the Cancer Institute Hospital were retrospectively reviewed. S-1 at a standard dose of 50 mg/body was administered twice daily for four weeks, followed by a two-week rest period. This was repeated every six weeks until disease progression or unacceptable toxicity. RESULTS Thirty-five patients were assessed. The patients were heavily pretreated with anthracycline (100%), taxane (paclitaxel or docetaxel) (100%), capecitabine (100%), vinorelbine (71%), and mitomycin (69%). Median follow-up time of patients was 9.6 months (range, 1.2-26.6). ORR was 3% (95% confidence interval: 0-9%), and CBR was 20% (95% confidence interval: 6-33%). Time to treatment failure was 2.8 months. Overall survival was 21.4 months. Grade 1 or 2 adverse events were observed in 17% and 13%, respectively. Grade 3 events occurred as anorexia (9%), nausea (9%), vomiting (9%), diarrhea (14%), fatigue (3%), and elevation of AST/ALT (3%). No grade 3 was seen as hand-foot syndrome. Neither grade 3 nor 4 was observed in bone marrow suppression. CONCLUSIONS S-1 was fairly well tolerated, but demonstrated very limited activity in capecitabine-pretreated patients who had already been exposed to anthracycline and taxane. It was suggested that S-1 clinically exhibited cross-resistance to capecitabine.

Abstract
The treatment of advanced breast cancer is continually evolving, with the aim of improving the quality and duration of remission and, in some instances, survival. In this setting, the importance of quality of life cannot be underestimated, and growing attention is being paid to treatment convenience and compliance. New anticancer agents have improved efficacy, but for many of them, toxicity often remains a problem. Vinorelbine seems to represent both an active and a well tolerated treatment for metastatic breast cancer. In particular, the oral formulation has similar efficacy to that of the injectable formulation and has demonstrated generally favourable tolerability, with a high degree of acceptance by both patients and physicians. The availability of this and other novel, well tolerated and effective treatments provides greater potential to tailor treatment to meet individual patient needs and, therefore, also provide the potential to improve patient outcomes. Preliminary data suggest that oral vinorelbine may permit continued, effective chemotherapy when further parenteral therapy with more intensive and more toxic agents is considered inappropriate. Early findings also suggest that oral vinorelbine, when administered together with another new oral agent, capecitabine, may be a valid choice in metastatic breast cancer treatment. Furthermore, vinorelbine plus the monoclonal antibody trastuzumab, with or without oral capecitabine, appears to be another regimen that may be worthy of additional study in patients with human epidermal growth factor-2 positive advanced breast cancer.

Abstract
OBJECTIVES The aim of this retrospective study was to evaluate the activity and toxicity of a combined chemotherapy containing mitomycin, folinate, and 5-fluorouracil (MiFoFU) in patients with advanced metastatic breast cancer and reduced performance status, ie, elderly patients or heavily pretreated patients. METHODS We studied the charts of 76 patients with progressive metastatic breast cancer who received MiFoFU chemotherapy at our institution between 1997 and 2003. Primary end points were response and time-to-progression (TTP); secondary end points were overall survival (OAS) and tolerability. RESULTS Median age was 57 years. Seventeen patients had > or =2 palliative cytostatic treatments before; 19 patients were older 65 years. Patients received a median of 6 cycles. Clinical benefit rate was 58%. After MiFoFU, median TTP and OAS were 8 months and 14 months, respectively. Main nonhematologic toxicity was stomatitis (grade I/II, 21%) and diarrhea (grade I/II, 37%). Grade III/IV hematotoxicity was seen in 18 patients (24%). CONCLUSIONS A combined MiFoFU chemotherapy is a well-tolerated treatment option in the palliative therapy for patients with metastatic breast cancer. In particular, the favorable efficacy/toxicity ratio in intensively pretreated or elderly patients makes this combination a reasonable alternative within these settings.

Abstract
The emergence of trastuzumab has drastically changed therapy for breast cancer. Trastuzumab (Herceptin; Genentech) is a recombinant humanized monoclonal antibody that targets an epitope in the extracellular domain of the human epidermal growth factor receptor 2 (HER2) protein. HER2 is a member of a family of four transmembrane receptor tyrosine kinases that regulate cell growth, survival, and differentiation via multiple signal transduction pathways. Overexpression of HER2 or amplification of the HER2 gene occurs in 20%-30% of human breast cancers. Preclinical models have demonstrated that this antibody has significant antitumor activity as a single agent, and it also has a synergy with certain chemotherapeutic drugs. Phase II and III clinical trials performed in women with metastatic breast cancers that overexpress HER2 have shown trastuzumab to have clinical activity when used as monotherapy, while also improving survival when used as a first-line therapy in combination with chemotherapy. At present, clinical investigations are focusing attention on the efficacy of trastuzumab in both the adjuvant and neoadjuvant setting, as well as in the metastatic setting. In this review, we describe the developments and current status of trastuzumab-based treatment for breast cancer.

Abstract
BACKGROUND A one-stage phase II trial was conducted to assess the tumor response rate and toxicity profile of single agent oral vinorelbine as first or second-line chemotherapy for women at least 65 years of age with metastatic breast cancer. PATIENTS AND METHODS Twenty-five patients with metastatic breast cancer aged > or = 65 years of age were enrolled to receive oral vinorelbine on a weekly basis. The oral vinorelbine was given at 60 mg/m2 weekly for the first four doses and was increased to 70 mg/m2 for the subsequent administrations if there was no grade 4 neutropenia or no more than one episode of grade 3 neutropenia. Therapy was continued until progression or intolerable toxicity. RESULTS Twenty-five patients were included and evaluable for analysis. One patient (4%) achieved a partial response (PR) that lasted for more than 13 months. Two additional patients remained stable for at least 6 months for a clinical benefit rate (PR + stable disease) of 12%. The 1-year survival rate was estimated to be 48% (95% CI 30% to 74.5%). Median time to progression was estimated to be 4.7 months (95% CI 2.0-5.5 months) and the 9-month disease progression-free rate was estimated to be 8% (95% CI 30.9% to 74.5%). The treatment was fairly well tolerated with grade 3 neutropenia in 12.5%, fatigue in 12.5% of the patients, and grade 2 neuromotor and neurosensory toxicities in 12.5% and 8.3%, respectively. CONCLUSION Oral vinorelbine as a single agent at these dose and schedule in this population of women > or = 65 years is well tolerated but has a low level of objective efficacy for the treatment of metastatic breast cancer.

Abstract
Vinorelbine is a semi-synthetic vinca alkaloid that has been shown active in many tumour types and is currently registered for the treatment of advanced breast cancer (ABC) and non-small cell lung cancer (NSCLC). This agent has a generally favourable safety profile, and may be suitable for use in special populations such as the elderly and/or frail patient. However, with the taxanes firmly established as standard second line treatment for ABC after failure of an anthracycline, vinorelbine has been generally relegated for use as third line therapy, in competition with the oral compound capecitabine. More recently, the exciting results observed with the combination of vinorelbine and trastuzumab in patients with Her-2 overexpressing/amplified tumours, as well as the development of a reliable formulation and revised schedule of oral vinorelbine with proven activity in ABC appear to have revived the interest in this compound in the management of this disease. There are still a number of unanswered questions that will have to be addressed by properly designed, adequately powered randomised clinical trials.

Abstract
PURPOSE To observe whether in pretreated metastatic breast cancer patients with HER2-positive disease vinorelbine plus trastuzumab can produce different overall response rate (ORR), time to progression (TTP), and overall survival (OS) from women with HER2-negative tumors treated with vinorelbine alone. METHODS Between June 2000 and January 2004, 68 consecutive women were enrolled: 33 patients received vinorelbine (V) alone, while 35 patients were given trastuzumab plus vinorelbine (T+V) according to HER2 expression determined by immunohistochemistry. In tumors scored +2, HER2 gene amplification was determined by fluorescence in situ hybridization. RESULTS In patients treated with V (HER2-negative tumors) the ORR was 27.3%, while in those given T+V (HER2 positive tumors) the ORR was 51.4%. The median duration of response was 8 months for women treated with V and 10 months for those who received T+V. Patients given T+V had a longer TTP (9 months) and OS (27 months) than those receiving V alone (6 months and 22 months respectively). Toxicity was mild in both groups. Concerning cardiotoxicity in T+V group, 7 patients (20%) had left ventricular systolic disfunction. CONCLUSION Our data suggest that trastuzumab can change the natural history of HER2-positive metastatic breast cancer. In fact, when treated with trastuzumab, women with HER2-positive disease had better prognosis than patients with HER2-negative tumors. Conducting a formal phase III trial comparing vinorelbine alone vs vinorelbine plus trastuzumab in HER2-positive metastatic breast cancer women could be debatable.

Abstract
The efficacy of vinorelbine given as a continuous infusion was evaluated in 47 patients with breast cancer who had received previous treatment with first-line, second-line, and third-line chemotherapy including taxanes and/or anthracyclines. For inclusion into the study, patients were required to have histology-proven bi-dimensionally measurable disease. The treatment schedule was a bolus injection of vinorelbine 8 mg/m(2) administered over 5-10 minutes on day 1 followed by vinorelbine 8 mg/m(2) continuous infusion on days 1-4, every 21 days for 6 cycles. On an intent-to-treat basis, a 2% complete response rate and a 17% partial response rate were observed. The median time to progression was 2.4 months (95% CI, 1.83-2.97). Median survival was 7.73 months (95% CI, 4.48-10.98; range, 0.33-55.0 months). Major toxicities included febrile neutropenia in 40 cycles (24%) affecting 24 patients (51%) and 1 toxic death. Other nonhematologic toxicities included stomatitis (13%) and asthenia (13%). We conclude that this treatment shows considerable therapeutic activity, albeit at considerable toxicity costs, even in patients who have had multiple lines of prior chemotherapy. However, the results do not indicate clear advantages compared to the conventional weekly scheme of administration.

Abstract
As combinations and sequences of anthracyclines and taxanes increasingly become standard adjuvant treatment for early breast cancer, a major need for new treatment options for metastatic breast cancer will arise. Vinorelbine is highly active in the treatment of metastatic breast cancer, both as a single agent and in combination regimens. Furthermore, it is well tolerated, with a low incidence of subjective toxicities. It is anticipated, therefore, that vinorelbine will become increasingly utilized for treating metastatic breast cancer due to its favorable safety profile, good tolerability, and promising results in combination with other chemotherapy agents. Combinations with trastuzumab and newer molecular targeting agents are being explored. Doublets or triplets of vinorelbine with drugs other than anthracyclines and taxanes could be considered in the next generation of adjuvant and neoadjuvant trials, where it is anticipated that anthracycline/taxane combinations are likely to replace anthracycline/cyclophosphamide combinations as the mainstay of adjuvant treatment.
