Abstract
Breast cancer is the most common malignancy affecting females worldwide and is also among the top causes of all cancer-related deaths. Cardiovascular disease (CVD) is known to have the highest rate of mortality in women. There are several risk factors for both CVD and breast cancer that overlap, such as diet, smoking, and obesity, and also the current breast cancer treatment has a significant detrimental effect on cardiovascular health in general. Patients with exposure to potentially cardiotoxic treatments, including anthracyclines, trastuzumab, and radiation therapy, are more likely to develop CVD than non-cancer controls. Early detection and treatment may reduce the risk of the development of cardiac morbidity and mortality and would increase the number of breast cancer survivors. This article provides a comprehensive overview of breast cancer, identifies shared risk factors among breast cancer and CVD, and the cardiotoxic effects of therapy. It also reviews possible prevention and treatment of CVD in breast cancer patients and reviews literature about chemoprevention of cardiac disease in the setting of breast cancer treatment.

Abstract
Aims and Background To evaluate feasibility and efficacy of paclitaxel as a single agent or in combination with epirubicin in breast cancer taxane-naive patients who have failed previous high-dose chemotherapy. Methods Since February 1995, we have treated 32 patients in first relapse or progression after high-dose chemotherapy. Nineteen patients had metastatic breast cancer, 12 more than 3 involved axillary lymph nodes, and 1 inflammatory breast cancer at inclusion to the program. The median time to relapse after high-dose chemotherapy was 12 months (range, 2-43). At relapse, 12 patients were treated with epirubicin (90 mg/m2) plus paclitaxel (175 mg/m2) administered on day 1 every 21 days. In 20 patients who had previously received more than 350 mg/m2 of a cumulative dose of epirubicin and in one patient pretreated with chemotherapy containing mitoxantrone, we employed paclitaxel (175 mg/m2) alone. A median number of five courses was administered (range, 2-10). Results The overall response rate after 3 courses (29 of 32 patients were assessable) was 55% and after 6 courses (21 of 32 patients were assessable) was 57%. The median time to progression was 7 months (95% CI, 5.7-9.2), and median survival was 27.5 months (95% CI, 17.8-37.0). Toxicity was recorded for 180 cycles (epirubicin + paclitaxel for 62 cycles and paclitaxel alone for 118 cycles). The main toxicity in both regimens was hematologic. We observed WHO grade 3-4 neutropenia (in 8 patients, 25%), for which G-CSF (5 μg/kg/day sc) was employed. WHO grade 3-4 thrombocytopenia occurred in 2 patients (6%) and WHO grade 3 anemia in 1 patient (3%). Conclusions Our study showed that paclitaxel (alone or in combination with epirubicin) is feasible as salvage treatment in heavily pretreated patients.

Abstract
PURPOSE Neoadjuvant chemotherapy (NC) is yet to be established as the definitive treatment regimen for locally advanced breast cancer (LABC). The aim of this study was to determine the efficacy and toxicity of NC with epirubicin and paclitaxel. METHODS Between March 2007 and January 2009, 50 patients with LABC were enrolled in an open-label, phase II, multicenter study carried out at five distinct institutions. All patients were scheduled to receive four cycles of 60 mg/m(2) epirubicin and 175 mg/m(2) paclitaxel every 3 weeks, preoperatively, unless they developed profound side effects or disease progression. After curative surgery, two additional cycles of chemotherapy were administered to patients who had shown a positive response to NC. RESULTS In all, 196 cycles of chemotherapy were administered preoperatively; 47 of the 50 patients (94%) underwent all four cycles of designated treatment. Complete disappearance of invasive foci of the primary tumor, and negative axillary lymph nodes were confirmed in eight patients (16.0%), post operation. The cumulative 5-year disease-free survival rate was 70.0% for patients with complete remission (CR) and partial remission (PR), and 33.3% for patients with stable disease (SD) and progressive disease (PD) (p=0.018). The cumulative 5-year overall survival was 90.0% for patients who achieved CR and PR and 55.6% for patients who had SD and PD (p=0.001). Neutropenia (42.0%) was the most common grade 3/4 toxicity. However, none of the toxicities resulted in cessation of the treatment. CONCLUSION The encouraging pathologic response observed in the patients treated with epirubicin plus paclitaxel NC in this study suggests that epirubicin could be a substitute for doxorubicin, which is the most cardiotoxic agent.

Abstract
Relatively few cases of splenic metastases have been reported in the literature. Metastases to the spleen generally occur in the context of multivisceral involvement during the late stage of disease, while isolated splenic metastases are far less frequent. The primary cancer types commonly leading to splenic metastases are skin melanoma and gynecologic, colorectal and gastric cancers. Breast cancer is considered a rare source of splenic metastases, with few cases being reported in the literature. As a contribution to the literature, we report here on a case of splenic metastasis in a patient with breast cancer treated at the Department of Medical Oncology at our institution (Bellaria-Maggiore Hospital, Azienda USL of Bologna, Italy).

Abstract
BACKGROUND AND OBJECTIVES The modern management of locally advanced breast cancer includes a multimodal approach consisting of neoadjuvant chemotherapy (usually given as initial treatment), surgery, radiotherapy and adjuvant hormone therapy. This therapeutic approach converts many patients with initially unresectable disease to reasonable surgical candidates, with acceptable rates of loco-regional disease control. Induction of a pathological complete response (pCR) with modern chemotherapy agents or combined with immunotherapy, when applicable, should be one of the primary goals of neoadjuvant therapy in order to achieve better disease-free and overall survival in this subset of patients. Neoadjuvant chemotherapy is now standard for patients with locally advanced breast cancer, and this method of treatment has been extended to patients with earlier disease without affecting the treatment outcome. The objectives of this study were: (1) to conduct a phase II study to assess the efficacy and availability of epirubicin and paclitaxel in the neoadjuvant setting in women with locally advanced or high tumour-to-breast ratio breast cancer (no patient in either of these subgroups was a candidate for breast-conserving surgery prior to chemotherapy); (2) to evaluate the incidence of clinically relevant toxicity and, in particular, cardiac toxicity after treatment with an epirubicin + paclitaxel regimen in this group of patients. METHODS In this open-label, phase II, single-centre trial carried out in a university-affiliated tertiary-care municipal hospital, the rate of objective response, evaluated by clinical and pathological examinations, was the primary endpoint of the study. Other endpoints were the rates of breast-conserving surgery, local recurrence, disease-free survival and overall survival. Sixty patients were enrolled from September 1998 to September 2003 with a median follow-up of 56 months (range 16-96). All 60 women met the criteria for inclusion and agreed to participate in the study. They were diagnosed as having locally advanced or high tumour-to-breast ratio breast cancer that did not initially permit breast-conserving surgery. Epirubicin 75 mg/m(2) and paclitaxel 175 or 200 mg/m(2) were administered for five courses. Rates of adverse events were also analysed. RESULTS Eight patients experienced a pCR, five had a pathological partial response with an almost complete pathological response, and 39 were able to undergo breast-conserving surgery. Adverse effects were mostly of grade 1 or 2 severity. The most common adverse reactions were fatigue and neutropenic fever. One patient developed local recurrence during the median 56-month follow-up. Among examined biological markers, only estrogen receptor negativity was a strong predictor of a pCR. The rates of disease-free and overall survival following the neoadjuvant combination were similar for those who had tumours positive for the estrogen receptor and those who were negative for this. CONCLUSION Treatment with a combination of epirubicin and paclitaxel enabled lumpectomy in a substantial proportion of women who were previously deemed to not be suitable candidates for breast-conserving surgery. Clinical responses were not influenced by the initial tumour volume, and the only statistically significant predictor of pCR was the estrogen receptor status of the tumour.

Abstract
BACKGROUND Cardiac function impairment is a known side effect of epirubicin-based chemotherapy. Activation of natriuretic peptides is demonstrated in patients with heart failure. AIMS To identify prospectively the cardiotoxic profile of epirubicin-based chemotherapy in breast cancer patients and to evaluate the sensitivity of proANP and NT-proBNP as early biochemical markers of cardiac dysfunction. METHODS Forty cancer patients divided in two nonrandomized groups received either epirubicin and paclitaxel (Group A, n=26) or mitoxantrone and docetaxel (Group B, n=14). Control groups, Group C (n=13) and Group D (n=20), consisted of female patients with heart failure and healthy women respectively. Natriuretic peptides and LVEF were determined in all patients. RESULTS A statistically significant difference was recorded regarding LVEF before and after treatment in Group A patients (p=0.0001). Three patients had a significant LVEF decline between 10% and 18% from baseline values, while three reached an LVEF value below 50%. All of them presented an increase in proANP and NT-proBNP values (mean increase 270.31+/-124 fmol/ml and 303.57+/-108 fmol/ml, respectively). A significant correlation between the increase in plasma proANP (r=0.8, p<0.0001), as well as NT-proBNP (r=0.7, p<0.0001) and the decrease in LVEF was observed. Regarding Group A, levels of proANP increased from 192.25 fmol/ml before treatment to 287.84 fmol/ml after treatment (p=0.0001), whereas NT-proBNP increased from 152.50 to 242 fmol/ml (p<0.0001) respectively. During follow up, two Group A patients developed congestive heart failure twelve and fourteen months after the completion of chemotherapy respectively. A significant LVEF decline was recorded in both patients during the episode. Regarding Group B, no statistically significant differences were demonstrated. CONCLUSION ProANP and NT-proBNP levels might be used as reliable and sensitive markers in the detection of early cardiac impairment caused by epirubicin-based chemotherapy.

Abstract
Increased serum level of troponin-T and myoglobin has been recently reported to be related to cumulative anthracycline exposure. Left ventricular ejection fraction seems accurate in monitoring systolic function according to the latest version of Toxicity Criteria by chemotherapeutics 3.0. From January 2002, 20 patients with untreated advanced breast cancer received epirubicin (25 mg/m/week) and paclitaxel (80 mg/m/week) for 24 weeks. Troponin-T, myoglobin and biochemical serum enzymes circulating levels were measured immediately before and 4 h after epirubicin administration every week. Patients underwent electrocardiography and echocardiography at weeks 0, 8, 16 and 24. The number of courses administered was 352 (median 18, range 4-24). Epirubicin median dose administered was 600 mg/m and paclitaxel median dose administered was 1760 mg/m. Troponin-T never overcame the upper normal limit; one patient experienced troponin-T elevation without any clinical or instrumental sign of cardiac failure. Myoglobin never significantly increased with the exception of a patient who underwent several abdominal fluid drainages. Creatine kinase MB and C-reactive protein never moved outside the upper normal limit. No symptomatic cardiac event was recorded. In 55 performed echocardiograms at weeks 0, 8, 16 and 24, neither left ventricular ejection fraction nor early peak flow/atrial flow velocity registered any significant decrease. No troponin-T or myoglobin serum elevations and Left ventricular ejection fraction/early peak flow/atrial flow velocity changes were registered in our series of nonsymptomatic women during epirubicin/paclitaxel weekly chemotherapy in the absence of clinical cardiac toxicity. Longer follow-up is needed, however, to understand whether the troponin-T or myoglobin circulating level measurement is able to detect subclinical, early-stage doxorubicin-induced cardiotoxicity.

Abstract
Anthracyclines are a well-known cause of cardiotoxicity, but a number of other drugs used to treat cancer can also result in cardiac and cardiovascular adverse effects. Cardiotoxicity can result in the alteration of cardiac rhythm, changes in blood pressure and ischemia, and can also alter the ability of the heart to contract and/or relax. The clinical spectrum of these toxicities can range from subclinical abnormalities to catastrophic life-threatening, and sometimes fatal, sequelae. These events may occur acutely or may only become apparent months or years following completion of oncological treatment. Ischemia and rhythm abnormalities are treated symptomatically in most cases. Knowledge of these toxicities can aid clinicians to choose the optimal and least toxic regimen suitable for an individual patient.

Abstract
PURPOSE It was the aim of this study to evaluate the activity and tolerance of gemcitabine and oxaliplatin in pretreated metastatic breast cancer patients. METHODS Thirty-one patients who had disease relapse or progression after completion of an anthracycline- and/or taxane-based front-line regimen were treated with gemcitabine 1,500 mg/m(2) on days 1 and 8 as a 30-min intravenous infusion and oxaliplatin 130 mg/m(2) on day 8 as a 4-hour intravenous infusion, in cycles of 21 days. RESULTS Complete response occurred in 1 patient (3%) and partial response in 4 patients (13%) (overall response rate 16%; 95% confidence interval 3.2-29.1). Nine patients (29%) had stable disease and 17 (55%) progressive disease. Three partial responses (13%) were achieved among 23 patients receiving the regimen as third-line treatment. The median duration of response was 6 months (range 3-44.8), the median time to tumor progression 4.6 months (range 0.8-43.8), and the median survival 14.4 months (range 2.1-44.8). Grade 3 and 4 neutropenia occurred in 14 patients (45%), grade 3 and 4 thrombocytopenia in 6 patients (20%), and grade 2 and 3 asthenia in 4 patients (13%). There was no episode of febrile neutropenia. CONCLUSION The gemcitabine-oxaliplatin combination is a relatively active and well-tolerated salvage regimen in patients with heavily pretreated metastatic breast cancer.

Abstract
Purpose This randomized study compared maintenance paclitaxel with control in metastatic breast cancer patients not experiencing progression after first-line anthracycline/paclitaxel combination chemotherapy. Methods Between April 1998 and October 2003, 459 metastatic breast cancer patients received first-line combination chemotherapy with epirubicin or doxorubicin plus paclitaxel. Of these, 255 who had a response or stable disease were then randomly assigned onto the Maintenance Paclitaxel 1 (MANTA1) study, comparing eight courses of maintenance paclitaxel versus control (ie, no additional chemotherapy administration). The primary end point was progression-free survival. Results The study was prematurely concluded after a futility analysis, which was performed on 215 of the 238 patients randomly assigned within December 2002. Of these, 109 patients were assigned to maintenance paclitaxel and 106 were assigned to stopping chemotherapy. No significant difference in median progression-free survival was observed (8.0 months for maintenance paclitaxel and 9.0 months for control). There was no significant difference in median survival time (28.0 v 29.0 months). When the Bayesian method for monitoring clinical trials was applied to these data, even under an enthusiastic prior distribution, in the posterior distribution there was only an 8.6% chance of observing a 3-month improvement in median progression-free survival in the group receiving maintenance paclitaxel. After these results study accrual was closed. Conclusion Compared with control, the administration of additional courses of paclitaxel in patients who achieve disease control after six to eight courses of first-line anthracycline plus paclitaxel combination chemotherapy does not improve progression-free survival.

Abstract
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.

Abstract
BACKGROUND The expectation of improvement in patient survival with administration of new chemotherapy agents for metastatic breast carcinoma (MBC) is not consistently supported by data from clinical trials, which are often underpowered and have not detected moderate survival advantage. The aim of this study was to evaluate the impact of new agents on prognosis of MBC patients enrolled in clinical trials of first-line chemotherapy. METHODS Between 1983 and 2001, 640 MBC patients were entered into 6 consecutive trials; the present analysis was limited to patients. The date of diagnosis of metastatic breast disease was used to define 5 arbitrarily chosen 3-year time cohorts, 1983-1986, 1987-1989, 1992-1994, 1995-1997, and 1998-2001. Multivariate proportion of hazard (PH) models were used to evaluate changes in overall survival (OS) and progression-free survival (PFS) over time and to detect changes associated with the use of taxanes, while adjusting for differences in baseline factors among 5 cohorts. RESULTS Patient characteristics were evenly distributed across the 5 cohorts. Median OS was 18 months, 17.2 months, 19.2 months, 26.1 months, and 23.6 months, respectively, in cohorts 1983-1986, 1987-1989, 1992-1994, 1995-1997, 1998-2001 (P < 0.0001). Age, performance status, relapse-free survival, type of adjuvant treatment, metastatic site, and taxane first-line chemotherapy were all associated with survival. These data failed to provide an indication of temporal trend and suggested a reduction in hazard of death in two cohorts (1995-1997 and 1998-2001) where taxane was added to first-line chemotherapy. CONCLUSIONS The analysis provided evidence of improvement in prognosis of MBC patients that was associated with use of modern chemotherapeutic agents independent of time.

Abstract
The aim of the study was to evaluate cardiac safety of two different schedules of Epirubicin and Paclitaxel in advanced breast cancer patients enrolled into a multicenter randomized phase III trial. Patients received Epirubicin 90 mg m−2 plus Paclitaxel 200 mg m−2 (3-h infusion) on day 1 every 3 weeks for eight courses (arm A), or Epirubicin 120 mg m−2 on day 1 every 3 weeks for four courses followed by four courses of Paclitaxel 250 mg m−2 on day 1 every 3 weeks (arm B). Left ventricular ejection fraction was evaluated by bidimesional echocardiography at baseline, after four and eight courses of chemotherapy and every 4 months during follow-up. Baseline median left ventricular ejection fraction was 60% in arm A and 65% in arm B; after four courses, figures were 57 and 60%, respectively. After eight courses, the median left ventricular ejection fraction in arm A declined to 50% while no further reduction was detected in arm B by adding four courses of high-dose Paclitaxel. Seven episodes of congestive heart failure were observed during treatment in arm A. Present monitoring demonstrated that the risk of congestive heart failure or impairment in the cardiac function correlated only with the cumulative dose of Epirubicin; no impact on cardiotoxicity can be attributed to high-dose Paclitaxel.

Abstract
UNLABELLED We investigated myocardial fatty acid metabolism in taxan-induced myocardial damage in patients with advanced lung cancer. PATIENTS AND METHODS Twenty-five patients with non-small-cell lung cancer were treated with taxan combined with carboplatin intravenously for three cycles. Myocardial SPECT imaging using 99mTc-methoxyisobutyl isonitrile (MIBI) and 123I-15-(p-iodophenyl)-3-(R,S)-methylpentadecanoic acid (BMIPP) was performed successively before and after chemotherapy. Regional uptake scores of BMIPP and MIBI were visually assessed and total uptake scores and the number of abnormal segments were calculated. Left ventricular ejection fraction (LVEF) was obtained by first-pass radionuclide angiocardiography using MIBI. Postmortem pathological examination was performed in 5 patients. RESULTS Total BMIPP uptake scores after chemotherapy were significantly lower than those before chemotherapy (23.4 +/- 3.4 vs. 26.6 +/- 0.8; p < 0.001). Mean LVEF showed a significant decrease after chemotherapy. Of the 25 patients, 4 exhibited a decrease in LVEF of more than 10%, 1 had a decrease in LVEF to below 50%, and 1 developed congestive heart failure. These 6 patients had significant decreases in total BMIPP uptake scores and increases in the number of abnormal segments as compared with the other 19 patients. Histopathological examination of myocardial tissue showed interstitial edema and disarrayed myocardial cells. CONCLUSION Taxan impairs myocardial fatty acid metabolism. 123I-BMIPP myocardial SPECT is useful for evaluating the cardiotoxicity induced by taxan.

Abstract
To evaluate the impact of prior adjuvant chemotherapy on response rate (RR), progression-free (PFS) and overall survival (OS) of metastatic breast cancer patients treated with epirubicin/paclitaxel (ET) regimens. In all, 291 patients enrolled in five studies in metastatic breast cancer were analysed: 101 (35%) were chemonaive, 109 (37%) had received adjuvant CMF and 81 (28%) adjuvant anthracyclines. Response rate to ET was 66%. Response rate was 63% for cyclophosphamide plus methotrexate plus 5-fluorouracil (CMF), 67% for prior anthracyclines and 68% in chemonaive patients (P=0.5). By multivariate analysis, adjusted odds ratio for response was 0.81 (95% CI: 0.37-1.79) for CMF and 0.92 (95% CI 0.43-2.01) for anthracyclines (P=0.86). The CR rates were 14% for both CMF and anthracyclines and 22% for chemonaive patients (P=0.2). By multivariate analysis, the relative odds of CR for CMF or anthracyclines were 0.40 and 0.39 as compared to chemonaive patients (P=0.036). The median PFS was 11.0 months for prior CMF, 10.2 months for anthracyclines and 12.5 months in chemonaive patients (P=0.33). In multivariate Cox's model, a nonsignificant increase in the risk of progression was seen in patients treated with adjuvant CMF or anthracyclines. The median OS was 23.8 months for CMF, 20.2 months for anthracyclines and 27.5 months in chemonaive patients (P=0.61). The same, nonsignificant, association was seen in multivariate analysis. The ET regimens provide satisfactory results in metastatic breast cancer, regardless of previous adjuvant chemotherapy.

Abstract
The objective of this study was to compare the safety and efficacy of carboplatin plus epirubicin and paclitaxel (TEC) to carboplatin and paclitaxel (TC), in the treatment of epithelial ovarian, peritoneal, or tubal carcinoma. Between March 1999 and August 2001, 887 patients were randomized to receive six to nine cycles of paclitaxel (175 mg/m2, 3 h intravenously) followed by carboplatin (AUC 5, Calvert formula) with or without epirubicin (75 mg/m2 intravenously prior to paclitaxel), on a 3-weekly schedule. The primary endpoint was progression-free survival. Demographic information: Residual disease <1 cm was reported on 41% of patients. At the end of treatment, 65% in the TEC and 55% in the TC arm had achieved a clinical complete response, and 18 and 25% a clinical partial response resulting in an overall response rate of 83% in the TEC and 80% in the TC arm, whereas 7 and 9% had progressive disease, respectively. The three-drug combination produced a markedly higher myelotoxicity, resulting in a higher frequency of febrile neutropenia (12.5% of the TEC and 1.5% of the TC patients) and a higher number of dose reductions and treatment delays. Cycle prolongation above seven days was seen in 7 and 5% of cycles in the TEC and TC arm, respectively. Stomatitis > or = grade 3 was also higher with TEC (4% TEC and 0.5% TC). Reductions in left ventricular ejection fraction of more than 15% after six courses were slightly more common with the TEC regimen (3% versus 1.5%), but the difference was not statistically significant (P = 0.2). In conclusion, treatment with the TEC combination produced a higher rate of complete responses than treatment with the TC combination. Toxicity was manageable. Long-term survival data are awaited.

Abstract
In this phase II, multicentre trial, patients with metastatic breast cancer (MBC) were treated with a combination of gemcitabine, epirubicin and paclitaxel (GET). The primary objective of this study was to determine the tolerability and activity in terms of complete responce (CR) and overall response rate of the GET combination in this patient population. Patients with no prior treatment for MBC, and at least one bidimensionally measurable lesion received gemcitabine 1000 mg m−2 intravenously (i.v.) over 30 min on days 1 and 4, followed by epirubicin i.v. at 90 mg m−2 on day 1, and paclitaxel 175 mg m−2 over 3 h on day 1, every 21 days, up to eight courses. From May 1999 to June 2000, 48 patients were enrolled from seven Italian institutions. A total of 297 chemotherapy courses were administered with a median of six cycles patient−1 (range 1–8). Seven patients (15%) obtained CR and 27 patients (56%) had partial responce, for an overall response rate of 71% (95% CI: 58.3–83.7). After a median follow-up of 23.7 months (range 7.0–34.4), median progression-free survival was 10.5 months (95% CI: 9.2–11.7), and median overall survival 25.9 months. The main haematological toxicity consisted of grade 3 or 4 neutropenia that occurred in 62% of cycles (22% grade 4 and 40% grade 3). The GET combination is active and well tolerated as first-line chemotherapy for MBC.

Abstract
BACKGROUND The authors performed a randomized trial comprising patients with metastatic breast carcinoma (MBC). They used a noninferiority design to evaluate whether the results of sequential administration of epirubicin and paclitaxel were not markedly worse than the concomitant administration in terms of objective response rates (ORRs). Toxicity profile, quality of life (QOL), and pharmacoeconomic evaluations were evaluated as well. METHODS In the current study, 202 patients with MBC were randomized to receive either the combination of epirubicin at a dose of 90 mg/m2 plus paclitaxel at a dose of 200 mg/m2 for 8 cycles (concomitant arm, n = 108) or epirubicin at a dose of 120 mg/m2 for 4 cycles followed by paclitaxel at a dose of 250 mg/m2 over 3 hours for 4 cycles every 21 days (sequential arm, n = 94). RESULTS The authors rejected the null hypothesis that the sequential treatment is less active than the standard concomitant regimen (ORRs: concomitant = 58.5%, sequential = 57.6%). The median progression-free and overall survival periods were 11.0 months (95% confidence interval [95% CI], 9.7-12.3) and 20.0 months (95% CI, 17.2-22.6), respectively, in the concomitant arm and 10.8 months (95% CI, 7.9-13.6) and 26 months (95% CI, 18.1-33.8), respectively, in the sequential arm (P = not significant). Patients who received the sequential regimen experienced a higher incidence of Grade 3/4 (according to the World Health Organization grading system) neutropenia (62.2% of courses vs. 50.62%; P = 0.003) and Grade > or = 2 neuropathy (45.5% vs. 30.4% of patients; P = 0.03), whereas 6 patients who received the concomitant regimen developed Grade II cardiotoxicity according to New York Heart Association criteria. QOL analyses failed to provide clear differences. CONCLUSIONS The sequential administration of epirubicin and paclitaxel at full doses was found to be as active as their association. Therefore, both the sequential and the combined administration were acceptable options.

Abstract
PURPOSE The efficacy of anthracyclin-containing adjuvant chemotherapy of node-positive breast cancer can be further improved by adding sequential paclitaxel (T). There is also clinical evidence that replacing cyclophosphamide (C) with vinorelbin (V) might further reduce toxicity. In order to assess the safety of these options, we initiated a clinical cohort study of epirubicin/cyclophoshamide and epirubicin/vinorelbine with or without sequential paclitaxel. METHOD Patients with node-positive (1-3) breast cancer were assigned to open-label epirubicin/vinorelbine (EV), epirubicin/vino-relbine and sequential paclitaxel (EV/T), epirubicin/cyclophosphamide (EC) or epirubicin/cyclophosphamide plus sequential paclitaxel (EC/T) therapy. RESULTS Fifty four outpatients received a total of 304 chemotherapy cycles. There were significant differences in grade III/IV anemia only between the EV/T and EC/T groups, in favor of the EC/T group (P=0.002). CONCLUSIONS The safety of paclitaxel is not impaired when given sequentially after administration of the two anthracyclin-containing regimens. The exchange of cyclophosphamide against vinorelbine leads to deteriorating safety of the EC/T regimen.

Abstract
OBJECTIVE We conducted a multi-institutional phase II study to evaluate the tolerability and activity of a sequential schedule of treatment with doxorubicin and docetaxel in chemotherapy-naive women with advanced breast cancer. METHODS A total of 73 patients with PS (ECOG) 0-2, aged <70 years and adequate bone marrow, renal, liver and cardiac functions were included in the study (13 stage III B and 60 stage IV). The schedule of administration was doxorubicin 50 mg/m2 by intravenous (i.v.) 30 min injection on day 1 followed the day after by docetaxel 75 mg/m2, by i.v. 60 min infusion. Cycles were repeated every 28 days. RESULTS Overall, the median number of administered cycles was 6 (range 1-14). The most common toxicity was hematological, with 56.2% of the patients who experienced grade 3-4 neutropenia. However, febrile neutropenia occurred only in 2.8% of the cases. The median cumulative dose of doxorubicin was 350 mg/m2 (range 50-700 mg/m2). Eleven patients (15.4%) were documented to have >10% but <20% decrease in the left ventricular ejection fraction. No case of congestive heart failure was recorded. No patient experienced treatment-related death. Among the 68 evaluable patients, the overall objective response rate was 73.5% (95% confidence limits: 63-84%): 10 patients (14.7%) obtained a complete remission and 40 (58.8%) had a partial response. Only 10 patients (14.7%) experienced progressive disease. The median duration of response was 10 months (2-54+). CONCLUSION This sequential treatment with doxorubicin and docetaxel is an effective, feasible and a well-tolerated regimen. The main toxicity was neutropenia. The lack of cardiotoxicity is an important advantage of such a doxorubicin-docetaxel combination and it justifies phase III comparative studies with other anthracyclines/taxanes containing schedules in both advanced and early-stage breast cancer.

Abstract
The purpose of our study was to evaluate the feasibility and efficacy of weekly docetaxel/paclitaxel in pretreated advanced breast cancer patients. Twenty-six patients with metastatic breast cancer were included in this study. Three different schedules of treatment were administered. The starting schedule, A1, consisted of docetaxel 60 mg/m2 on day 1 plus paclitaxel 60 mg/m2 over 1 hour, weekly for 18 weeks; this schedule was considered feasible if at least 70% of the planned doses were given on time and without reduction. Schedule A2 consisted of the same doses administered on days 1 and 8 every 3 weeks, and schedule B consisted of docetaxel 25 mg/m2 followed by paclitaxel 40 mg/m2 for 1 hour on days 1 and 8 every 3 weeks for a total of 6 cycles. All patients had received prior anthracyclines, and 19 patients were pretreated with taxanes. Seventy-seven percent of patients had received at least 2 prior lines of chemotherapy. Twenty-five patients are assessable for toxicity and efficacy. A total of 109 cycles of chemotherapy have been administered, with a median of 4 cycles per patient (range, 1-8 cycles). The median delivered dose intensity was 27 mg/m2/week for paclitaxel (range, 18-50 mg/m2/week) and 17 mg/m2/week (range, 12-39 mg/m2/week) for docetaxel. Six patients received schedule A1. This schedule was considered not feasible due to neutropenia grade > 2, mucositis, and diarrhea grade 2, which required dose reduction/omission in 33% of administrations. For this reason, treatment in the following 5 patients was omitted on day 15 (schedule A2). Schedule B was found to be more feasible with 16% of dose reductions/omissions. The overall response rate was 68% (95% CI, 50%-86%) with a median duration of response of 10 months (range, 2-18+ months). Treatment was well tolerated; myelosuppression was rare and grade 3 cutaneous toxicity was observed in only 2 patients. In conclusion, weekly docetaxel/paclitaxel is active at low dosages and was well tolerated as salvage chemotherapy in metastatic breast cancer. This regimen represents a valid option as a salvage treatment in taxane- and anthracycline-pretreated patients.

Abstract
The anthracycline glycoside antibiotics represent a group of potent anticancer agents with a wide spectrum of activity against solid tumours and haematological malignancies, and are the mainstay of a large number of clinical protocols for the treatment of adult and childhood neoplastic diseases. Their clinical activity is limited, however, by acute and chronic adverse effects. Myelosuppression, predominantly neutropenia and leucopenia, is the dose-limiting toxicity; in addition to this, mucositis, nausea, vomiting and alopecia are frequent, whereas hepatopathy, characterised by elevated bilirubin concentrations, occurs less frequently. Cardiotoxicity is a major adverse effect of the anthracycline antibiotics and can be acute or chronic; in the acute setting, electrocardiographic abnormalities may be seen, including ST-T elevations and arrhythmias, but chronic cardiotoxicity represents a serious adverse effect that may be lethal due to the development of irreversible, cumulative dose-dependent, congestive cardiomyopathy. The occurrence of toxicity displays a marked interindividual variation, and for this reason the pharmacokinetics and pharmacodynamics of anthracyclines have been extensively investigated in order to identify integrated models that can be used in the clinical setting to prevent the development of serious toxicity, mainly leucopenia, and maximise tumour exposure. Pharmacokinetics has been recognised to influence both the toxicity and the activity of anthracyclines; in particular, there is increasing evidence that the mode of administration plays an important role for cumulative cardiotoxicity and data indicate that bolus administration, rather than continuous infusion, appears to be an important risk factor for anthracycline-induced cardiomyopathy, thus implying that this type of toxicity is maximum concentration-dependent. On the contrary, exposure to the drug, as measured by area under the curve, seems best related to the occurrence of leucopenia. Finally, the development of pharmacokinetic-pharmacodynamic models allows the simulation of drug effects and ultimately dose optimisation in order to anticipate important toxicities and prevent their occurrence by the administration of prophylactic treatments.

Abstract
The efficacy and safety of docetaxel-epirubicin chemotherapy in the treatment of metastatic breast cancer was investigated in Chinese women. Three-weekly cycles comprised epirubicin 75 mg/m2 i.v. followed 1 h later by docetaxel 75 mg/m2 i.v. After 3 cycles, responding patients received a further 3 cycles, followed by 3 cycles of docetaxel alone. Forty-six patients entered the study, of whom 37% had received prior adjuvant chemotherapy. Three patients withdrew due to toxicity and were not evaluable for response. There were five complete responses and 31 partial responses, giving an overall response rate of 83.7% (95% CI 72.7-94.8%). The median time to progression was 10.96 months (95% CI 7.76-12.86) and median survival was 24.2 months (95% CI 16.6-). The most common grade 3/4 adverse events were neutropenia (96% of patients) and neutropenia with fever (39%). Hepatotoxicity occurred in six patients, two being attributable to hepatitis B virus reactivation. No patients suffered grade 3/4 cardiac toxicity and there were no treatment-related mortalities. Quality of life aspects deteriorated after 3 cycles, but there was a trend towards improved emotional aspects after 9 cycles. We conclude that docetaxel-epirubicin chemotherapy is highly effective for recurrent metastatic/locoregional breast cancer, with myelosuppression being the main toxicity.

Abstract
PURPOSE This phase II multicenter trial was aimed at investigating the activity of epirubicin-vinorelbine combination as first-line chemotherapy in metastatic breast cancer patients. PATIENTS AND METHODS Ninety-seven patients with metastatic breast cancer and no prior exposure to anthracyclines received the following regimen: epirubicin 100 mg/m(2) by intravenous (IV) bolus infusion on day 1 plus vinorelbine 25 mg/m(2) by 30-minute IV infusion on days 1 and 5, every 3 weeks for up to eight cycles. All patients also received granulocyte colony-stimulating factor (G- CSF) on days 7 to 12 of every cycle. RESULTS Objective responses, confirmed at least 4 weeks after the first documentation, were observed in 65 out of 92 assessable patients (70.6%; 95% CI, 62% to 80%). Disease remained stable in 17 patients (18.5%). Responses were observed in all disease sites, being 94% in soft tissue, 60% in bone, and 66% in visceral disease. Median time to response, median duration of response, median time to progression, and median overall survival were 2, 9, 10, and 26 months, respectively. The dose-limiting toxicity was neutropenia, which was grade 4 in 36% of the patients, and was accompanied by fever in 26% of the cases. Grade 3 to 4 mucositis was encountered in 28% of the patients. Other toxicities were mild to moderate. No cardiotoxicity was observed. CONCLUSION The epirubicin-vinorelbine combination with G-CSF support has been shown in this study to be highly active as first-line treatment of metastatic breast cancer patients, with significant although transient toxicity. This justifies further evaluation in the neoadjuvant setting and in early-stage breast cancer.

Abstract
BACKGROUND The objectives of this study were to investigate the disposition of gemcitabine, epirubicin, paclitaxel, 2',2'-difluorodeoxyuridine and epirubicinol, and characterize the pharmacokinetic and pharmacodynamic profile of treatment in patients with breast cancer. PATIENTS AND METHODS The drug dispostion in 15 patients who received gemcitabine 1000 mg/m2, epirubicin 90 mg/m2 and paclitaxel 175 mg/m2 (GEP) on day 1 of a 21-day cycle, was compared with that of patients treated with epirubicin 90 mg/m2 and paclitaxel 175 mg/m2 (EP, n = 6) and epirubicin 90 mg/m2 alone (n = 6). Drug and metabolite levels in plasma and urine were assessed by high-performance liquid chromatography and parameters of drug exposure were related to hematological toxicity by a sigmoid-maximum effect (Emax) model. RESULTS Paclitaxel administration significantly increased the epirubicinol area under the concentration-time curve, from 357+/-146 (epirubicin) to 603+/-107 (EP) and 640+/-81 h x ng/ml (GEP), and reduced the renal clearance of epirubicin and epirubicinol by 38 and 52.2% and 34.5 and 53% in GEP- and EP-treated patients, respectively, compared with epirubicin alone. Gemcitabine had no apparent effect on paclitaxel and epirubicin pharmacokinetics, and renal clearance of epirubicin and epirubicinol. The only pharmacokinetic/pharmacodynamic relationship observed was between neutropenia and the time spent above the threshold plasma level of 0.1 micromol/l (tC0.1) of paclitaxel, with the time required to obtain a 50% decrease in neutrophil count (Et50) of GEP being 7.8 h, similar to that of EP. CONCLUSIONS Paclitaxel and/or its vehicle, Cremophor EL, interferes with the disposition and renal excretion of epirubicin and epirubicinol; gemcitabine has no affect on epirubicin and paclitaxel plasma pharmacokinetics and renal excretion of epirubicin, while neutropenia is not enhanced by gemcitabine.

Abstract
AIMS To investigate the pharmacokinetics and pharmacodynamics of epirubicin and paclitaxel in combination, as well as the effects of paclitaxel and its vehicle Cremophor EL on epirubicin metabolism. METHODS Twenty-seven female patients with metastatic breast cancer received epirubicin 90 mg m-2 i.v. followed 15 min or 30 h later by a 3 h i.v. infusion of paclitaxel 175, 200 and 225 mg m-2. Plasma concentrations of paclitaxel, epirubicin and epirubicinol were measured and the relationship between neutropenia and drug pharmacokinetics was evaluated using a sigmoid maximum effect (Emax) model. Finally, the influence of paclitaxel and Cremophor EL on epirubicin metabolism by whole blood was examined. RESULTS An increase in epirubicinol plasma concentrations occurred after the start of the paclitaxel infusion, resulting in a significant increase in the area under the plasma concentration-time curve (AUC) of epirubicinol (+0.5 micromol l-1 h [95% CI for the difference: 0.29, 0.71],+0.66 micromol l-1 h [95% CI for the difference: 0.47, 0.85] and +0.82 micromol l-1 h [95% CI for the difference: 0.53, 1.11] at paclitaxel doses of 175, 200 and 225 mg m-2, respectively), compared with epirubicin followed by paclitaxel 30 h later (0.61+/-0.1 micromol l-1 h). A significant increase in epirubicin AUC (+0.74 micromol l-1 h [95% CI for the difference: 0.14, 1.34] and +1.09 micromol l-1 h [95% CI for the difference: 0.44, 1.74]) and decrease in drug clearance (CLTB) (-25.35 l h-1 m-2[95% CI for the difference: -50.18, -0.52] and -35.9 l h-1 m-2[95% CI for the difference -63,4,-8,36]) occurred in combination with paclitaxel 200 and 225 mg m-2 with respect to the AUC (3.16+/-0.6 micromol l-1 h) and CLTB (74.4+/-28.4 l h-1 m-2) of epirubicin followed by paclitaxel 30 h later. An Emax relationship was observed between neutropaenia and the time over which paclitaxel plasma concentrations were equal to or greater than 0.1 micromol l-1 (tC0.1). The tC0.1 value predicted to yield a 50% decrease in neutrophil count was 7.7 h. Finally, Cremophor EL markedly inhibited the metabolism of epirubicin to epirubicinol in whole blood. CONCLUSIONS Paclitaxel/Cremophor EL affects the disposition of epirubicinol and epirubicin. Furthermore, the slope factor of the Emax relationship between neutropenia and tC0.1 of paclitaxel suggests that the drugs might also interact at the pharmacodynamic level.

Abstract
In order to explore activity and pharmacokinetic data of a docetaxel-epirubicin combination we analyzed a population of 60 metastatic breast cancer patients. All the patients had an ECOG performance status < 3; 41 patients (68%) had visceral metastases as dominant site of disease, including 33% with liver metastases. Three or more involved organs were present in 43% of patients; 35% had received prior hormonotherapy; 10% for metastatic disease. Twenty-five patients (42%) had received prior adjuvant chemotherapy; 15% a CAF regimen. Twenty per cent of patients had less than 12 months disease-free interval. Docetaxel and epirubicin were both given at a dose of 75 mg/m2 i.v. d. 1 every 3 weeks. After a median of six cycles we had 5 CR (8.3%), 40 PR (66.6%), 7 NC (11.6%), and 8 PD (13.3%). Response rates in patients with visceral and liver metastases were 78% and 55% respectively. Premenopausal status, < 1 year disease free survival and > 3 metastatic sites were associated with a lower response rate. After a median follow-up of 19 months (12-36), median disease-free survival is 11 months and median overall survival has not been reached. Grade 4 neutropenia was observed in 75% of courses but with febrile neutropenia in 6.2% of courses only. Non-hematologic toxicity wasn't clinically important. A NYHA class III reversible cardiac failure was observed in one patient (1.6%). The pharmacokinetic evaluation in 16 patients has shown that docetaxel transiently interfered with epirubicin plasma level when docetaxel was administered 1 h after epirubicin.

Abstract
The purpose of this study was to evaluate the activity and tolerance of high-dose leucovorin (LV) and infusional 5-fluorouracil (5-FU) in combination with conventional doses of cyclophosphamide (CPM) as salvage chemotherapy in patients with metastatic breast cancer (MBC) pretreated with anthracyclines and taxanes. 41 patients (median age 59 years) with MBC refractory or resistant to anthracyclines and taxanes were enrolled. The patients' performance status (WHO) was 0 in 10 patients (24%), 1 in 22 (54%), and 2 in 9 (22%). 30 (73%) patients had received 2 or more prior chemotherapy regimens. Cyclophosphamide (600 mg m(-2)) was given i.v. bolus on day 1 and LV (500 mg m(-2) d(-1)) as a 2-h infusion followed by 5-FU (1.5 g m(-2) d(-1)) over a 22 h c.i. for 2 consecutive days. Cyclophosphamide was administered every 28 days while 5-FU/LV every 14 days. In an intention-to-treat analysis, complete response (CR) was achieved in 2 (4.9%) patients and partial response (PR) in 9 (22%) (overall response rate 26.9%; 95% CI: 13.27-40.39%). Stable disease (SD) and progressive disease (PD) were observed in 9 (22%) and 21 (51%) patients, respectively. The overall response rate was 6% and 40% in patients with primary and secondary resistance to anthracyclines/taxanes, respectively (P = 0.047). The median duration of response and the median time to disease progression was 8 and 9.5 months, respectively. The median overall survival was 13 months and the probability for 1-year survival 51%. Grade 3/4 neutropenia occurred in 9 (22%) patients and 4 (9%) patients developed grade 3/4 thrombocytopenia. Non-haematological toxicity was mild. There were no cases of febrile neutropenia, toxic deaths or treatment-related hospital admissions due to toxicity. The combination of high-dose 5-FU/LV with conventional doses of cyclophosphamide is a well tolerated and effective salvage regimen in patients with MBC heavily pretreated with both anthracyclines and taxanes.

Abstract
PURPOSE To determine the maximum tolerated dose (MTD) and the dose limiting toxicity (DLT) of docetaxel in combination with fixed doses of epirubicin. PATIENTS AND METHODS Women with locally advanced or metastatic breast cancer were given docetaxel, 60 mg/m2 in escalated doses by steps of 10 mg/m2, in association with two fixed doses of epirubicin (90 mg/m2, and 75 mg/m2). Since neutropenia was foreseen to be the most likely DLT, a third group with prophylactic G-CSF support was planned to define the MTD of docetaxel with 90 mg/m2 of epirubicin. Selected patients underwent pharmacokinetic evaluation of docetaxel. RESULTS Fifty-eight patients entered the study. At the first step (90 mg/m2 of epirubicin) the MTD was obtained at 60 mg/m2 of docetaxel. At the second step (75 mg/m2 of epirubicin) the MTD of docetaxel was 80 mg/m2. At the third step (epirubicin 90 mg/m2) G-CSF allowed a safe escalation of docetaxel up to 90 mg/m2. Neutropenia was the most common hematological adverse event. Without G-CSF, grade 4 neutropenia occurred in 69% of cycles, of which 11% was complicated by fever. In G-CSF group, grade 4 neutropenia and neutropenic fever occurred in 31% and 3%, respectively. Most frequent non-hematological adverse effects were asthenia (45%), nausea (39%) and mucositis (36%). No patient developed congestive heart failure. Two toxic deaths occurred. Overall response rate was 73% in 42 out of 58 patients, with no apparent epirubicin dose-related effect. No statistically significant effect of the two doses of epirubicin was observed in docetaxel pharmacokinetics. CONCLUSIONS On the basis of the toxicity profile, the docetaxel pharmacokinetics and the response rate observed, epirubicin 75 mg/m2 combined with docetaxel 80 mg/m2 can be recommended for further studies.

Abstract
PURPOSE To investigate the activity of the combination of gemcitabine (G) plus epirubicin (E) and taxol (T), (GET), in metastatic breast cancer, to evaluate the feasibility of this regimen as induction before high dose chemotherapy and to study the pharmacokinetic interactions of these three drugs. PATIENTS AND METHODS Metastatic breast cancer patients, with bidimensionally measurable disease were eligible. Treatment consisted of G 1000 mg/sqm days 1 and 4 plus E 90 mg/sqm day 1 plus T 175 mg/sqm/3 h day 1, every 21 days. After six courses of GET, patients aged less than 60 years, in complete or partial remission or stable disease entered a programme of high dose chemotherapy (HDCT), as consolidation treatment. RESULTS Thirtysix patients were included in this study. Grade 4 neutropenia was observed in 64% of the patients, with four episodes of febrile neutropenia; 39% of the patients experienced mild to moderate peripheral neuropathy; grade 2 and 3 mucositis occurred respectively in 9 (25%) and 6 (17%) patients. The overall response rate to GET was 92% (95% CI, 77.53%-98.25%); CR 31% and PR 61%. After six courses of GET, 25 patients received HDCT, leading to an overall response rate of 96% with 58% CR. At a median follow up of 25 months (range 8-39), 13 out of 36 patients are progression free and 26 alive. Median progression free survival is 21 months, while median overall survival has not yet been reached. The pharmacokinetic data show that G does not influence the interactions between E and T, while gemcitabine kinetics remains unchanged. CONCLUSIONS The results of the present study indicate that the addition of G to E plus T as front line treatment for advanced breast cancer is well tolerated with an ORR of 92%. On the basis of the high activity and interesting progression free and overall survival rates, the GET combination deserves further evaluation in randomized trials.

Abstract
The purpose of this study was to evaluate the activity and toxicity profile of dose-dense sequential chemotherapy with epirubicin (EPI) and paclitaxel in advanced breast cancer (ABC). From January to September 1997, 41 patients with recurrent or metastatic (stage IV) breast cancer were enrolled in the study. Their median age was 57 (range, 33-77) years and median performance status 0 (range, 0-2). Twenty patients had received adjuvant chemotherapy. The chemotherapeutic regimen consisted of 4 cycles of EPI 110 mg/m2 every 2 weeks followed by 4 cycles of paclitaxel, 225 mg/m2 over 3 hours every 2 weeks. G-CSF was administered prophylactically on days 2-10 of each cycle. 34 (83.0%) patients completed all 8 cycles of chemotherapy. A total of 304 cycles were administered, 259 (85.0%) of them at full dose. Thirty (10.0%) cycles were delivered with a delay. The relative median dose intensities of EPI and paclitaxel were 0.95. Most common grade 3-4 side effects were anemia (15.0%) neutropenia (12.0%), thrombocytopenia (5.0%), nausea/vomiting (10.0%), febrile neutropenia (7.5%), and alopecia (90.0%). Overall, 8 (19.5%) patients achieved a complete and 15 (36.5%) a partial response. Median duration of response was 8.4 (range, 3.1-15.5+) months. After a median follow-up of 18.5 months, median time to progression was 8.7 (range, 0.5-21+) months; median survival has not been reached yet. Dose-dense sequential chemotherapy with EPI and paclitaxel shows promising activity as first-line treatment in ABC. Randomized studies comparing this type of chemotherapy with the classical administration of the two drugs together every 3 weeks are ongoing.

Abstract
The taxanes' interaction with other anticancer drugs have been extensively investigated in in vitro and in animal models as well as in humans due to the outstanding antitumor activity in a broad range of malignancies. Paclitaxel and docetaxel are endowed of a rich and complex pharmacology whereby different pharmacodynamic effects are observed depending on the sequence of their administration in respect with the companion drug, and the type of drug that is combined. Pharmacokinetic interference is often but not always a basis of the pharmacodynamic effect. In addition, the vehicle of clinical formulation, especially Cremophor EL for paclitaxel, influence the pharmacological effect. Finally, new interaction based on as yet unknown mechanisms drive the two taxanes to multiple additive/synergistic relationships with new signal transduction drugs, such as modulators of the epidermal-growth-factor family of receptors and farnesyl-transferase inhibitors. The ongoing effort to better understanding such a rich pharmacology is worth continuing in view of designing new and better combinations of the taxanes.

Abstract
BACKGROUND Treatment of metastatic breast cancer (MBC) with paclitaxel (T) and doxorubicin has yielded high response rates but the regimen is associated with significant cardiac toxicity. Epirubicin (E) is a less cardiotoxic anthracycline which has also been combined with paclitaxel in the treatment of MBC. MATERIALS AND METHODS This paper is a review of studies evaluating the pharmacokinetics, toxicity profile, and efficacy of the ET combination in MBC. RESULTS The ET combination has been studied extensively in Europe. The unique pharmacokinetics of the combination do not lead to the accumulation of cardiotoxic metabolites as in the case of the doxorubicin-paclitaxel combination. In terms of efficacy, the ET combination yields an overall response rate of 50%-70% and complete response rate (CR) 10%-15% in MBC in the same range as the more recent doxorubicin paclitaxel studies. CONCLUSION In summary the ET combination is safe and effective in MBC. It is less cardiotoxic than the doxorubicin paclitaxel combination. Further studies with ET in both the adjuvant setting and in MBC are in progress.

Abstract
PURPOSE A pharmacokinetic interaction may cause increased cardiotoxicity of paclitaxel (PTX) and high cumulative dose of doxorubicin. We tested antitumor activity, tolerability, and pharmacokinetics of the lesser cardiotoxic epirubicin (EPI) and PTX (ET combination). PATIENTS AND METHODS Twenty-seven women with untreated metastatic breast cancer, median age of 56 years, and prominent visceral involvement (74%) were studied. Three-weekly EPI (90 mg/m(2)) and PTX (200 mg/m(2) over 3 hours) were given for a maximum nine cycles. EPI was administered 24 hours before PTX (E --> T) in cycle 1, and 15 minutes before PTX (ET) thereafter. EPI, epirubicinol (EOL), EPI-glucuronide (EPI-glu), EOL-glucuronide (EOL-glu), PTX, and 6alpha-OH-PTX were measured in plasma and urine in 14 women. RESULTS Patients received 205 cycles of ET and a median EPI dose of 720 mg/m(2). Grade 4 neutropenia (49% of cycles) was the most frequent toxicity. Cardiac contractility was decreased in five patients. Mild congestive heart failure occurred in two (7.4%). Response rate was 76% (28% complete). Median overall survival was 29 months. On the basis of intrapatient comparison in the first 24 hours of E --> T and ET cycles, PTX did not affect EPI disposition, but significantly increased plasma exposure to EOL (by 137%), EPI-glu (threefold) and EOL-glu (twofold). Urinary excretion of EPI dose went from 8.2% in E --> T to 11.8% in ET cycles. Clearance of PTX was 30% slower in ET than E --> T. ET cycles caused lower neutrophil nadir than E --> T (644 +/- 327 v 195 +/- 91, P <.05) CONCLUSION ET is feasible, devoid of excessive cardiac toxicity, and active. A reciprocal pharmacokinetic interference between the two drugs has pharmacodynamic consequences, and suggests a direct effect of PTX on EPI metabolism requiring ad hoc investigation.

Abstract
PURPOSE To compare the efficacy of two different schedules of epirubicin and paclitaxel, as first-line chemotherapy, in patients with advanced breast cancer (ABC). PATIENTS AND METHODS From October 1997 until May 1999, 183 eligible patients with ABC entered the study. Chemotherapy in group A (93 patients) consisted of four cycles of epirubicin at a dose of 110 mg/m(2) followed by four cycles of paclitaxel at a dose of 225 mg/m(2) in a 3-hour infusion. All cycles were repeated every 2 weeks with granulocyte colony-stimulating factor support. The therapeutic regimen in group B (90 patients) consisted of epirubicin (80 mg/m(2)) immediately followed by paclitaxel (175 mg/m(2) in a 3-hour infusion) every 3 weeks for six cycles. RESULTS In total, 79 patients (85%) in group A and 72 patients (80%) in group B completed treatment. The median relative dose-intensity of epirubicin was 0.96 in both groups, and that of paclitaxel was 0.96 and 0.97 in groups A and B, respectively. The complete response rate was higher in group A (21.5% v 9% P =.02). Nevertheless, there was no significant difference in the overall response rate between the two groups (55% v 42%, P =.10). Severe neutropenia was more frequently observed with concurrent treatment. After a median follow-up of 16.5 months, median time to progression was 10 months in group A and 8.5 months in group B (P =.27), and median survival was 21.5 and 20 months, respectively (P =.17). CONCLUSION The present study failed to demonstrate a significant difference in overall response rate between dose-dense sequential administration of epirubicin and paclitaxel compared with the combination of the two drugs given on the same day, even though the sequential treatment resulted in a significantly higher complete response rate.

Abstract
Anthracyclines are the gold standard monotherapy for metastatic breast cancer. Higher response rates are seen with drug combinations, especially with newer agents such as taxanes. The purpose of this study was to evaluate the toxicity and activity of the combination of paclitaxel and epirubicin in patients with advanced breast cancer. Thirty-five women with locally advanced or metastatic breast cancer (first and second relapse) were treated with epirubicin 75 mg/m2 and paclitaxel 200 mg/m2 3-weekly. Six centres recruited 35 patients; 34 (97%) were assessable for response. Eighteen had undergone prior chemotherapy, including six (17%) with anthracycline-containing regimens. Grade 4 neutropenia was found in 33 patients (94%), which was of 4 days' average duration; however, infective complications were rare, with only nine cycles (6%) complicated by neutropenic sepsis. There were two sepsis-related deaths. Symptomatic cardiotoxicity was infrequent, although a >15% decline in cardiac function was recorded in five patients (14%). Grade 3 peripheral neuropathy occurred in three patients (9%). The overall response rate was 50% (95% confidence interval 33-67) (complete response 12%; partial response 38%), with a median duration of response of 31 weeks. The median time to progression was 27 weeks, with a median survival of 48 weeks. This regimen appears to be a relatively safe, tolerable and effective treatment for advanced breast cancer. A United Kingdom Co-ordinating Committee for Cancer Research Phase III trial (AB-01) comparing this combination of epirubicin and paclitaxel with cyclophosphamide and paclitaxel completed accrual in November 1999.

Abstract
BACKGROUND Preliminary data from phase III randomized studies have failed to show benefit of HDC given as consolidation after anthracycline and alkylating-based chemotherapy in metastatic breast cancer (MBC). Moderate activity of induction regimens and selection of chemoresistant clones are among the possible reasons for these disappointing results. We therefore have designed a phase II study where high-dose alkylating agents are given as consolidation after an induction treatment including the most active agents (epirubicin and paclitaxel) without alkylating agents. PATIENTS AND METHODS Patients with MBC not previously treated with chemotherapy for metastatic disease were eligible. After six courses of epirubicin-paclitaxel +/- gemcitabine patients received a course of thiotepa 600 mg/m2 + melphalan 160 mg/m2 with hemopoietic support. Pharmacokinetic parameters of thiotepa and melphalan were measured and related to treatment outcomes. The L-VEF of the patients was monitored before and after treatment. RESULTS Forty-eight patients have been treated. Before HDC 14 patients were in CR, and 34 in PR. A median of 6.92 x 10(6) (range 1.53-16.6) CD34+ cells/kg were reinfused after HDC. Median days (range) to neutrophils > 0.5 x 10(9)/l and platelets > 20,000 x 10(9)/l were 9.5 (9-33) and 10 days (9-32), respectively. Symptomatic CHF was observed in two patients (4.1%). Cmax and AUC of thiotepa showed a linear relationship with time to progression (TTP) and overall survival (OS): r2 = 0.6. After HDC the conversion rate from PR to CR was 44.1%. At five years progression-free and overall survival rates are 37.5% and 65%, respectively. A treatment-related death was observed. CONCLUSIONS High-dose thiotepa and melphalan after an epirubicin-paclitaxel-containing treatment is feasible, devoid of significant cardiotoxicity and very active. Pharmacokinetic parameters of high-dose thiotepa might be linked to treatment outcome.

Abstract
The present trial was designed to determine the efficacy of the combination of gemcitabine/doxorubicin/paclitaxel (GAT) delivered every other week as first-line therapy in patients with metastatic breast cancer. From February 1998 to September 1999, 41 patients were included in this trial. Doses delivered were doxorubicin 30 mg/m2 on day 1 and paclitaxel 135 mg/m2 plus gemcitabine 2500 mg/m2 both given on day 2, every 14 days. Doses were selected from a previous phase I trial conducted at our institution. Eligibility criteria for the phase II trial included histologically confirmed metastatic breast cancer with bidimensionally measurable lesions; no prior therapy for metastatic disease; adjuvant or neoadjuvant chemotherapy was allowed if given more than 1 year before and cumulative doses of doxorubicin or epirubicin were less than 200 mg/m2 or 360 mg/m2, respectively; Eastern Cooperative Oncology Group (ECOG) performance status of 2 or less; and adequate hematological, hepatic, and renal function. Prophylactic use of granulocyte colony-simulating factor (G-CSF) was allowed if patients were not fully recovered (absolute neutrophil count greater than 1500/microL) from chemotherapy administration before the next dose. Left ventricular ejection fraction was determined initially, at the end of the study, and every 6 months thereafter. The patients' median age was 55 years (range, 33-68 years), and their median ECOG performance status was 0 (range, 0-1). Twenty-eight patients had received adjuvant therapy, 17 with epirubicin (none with doxorubicin). Metastases were present in the bone (19 patients), lung (19 patients), liver (11 patients), and soft tissues (18 patients). Twenty patients had one metastatic site and 21 had two or more sites. Efficacy was assessed on an intent-to-treat basis. A total of 216 cycles of GAT were given. Twenty-two percent of the courses were delayed or given at reduced doses mostly due to neutropenia or thrombocytopenia. G-CSF was required in 58% of the cycles. Grade 3/4 neutropenia was the main toxicity and appeared in 17 patients, one of whom had an episode of febrile neutropenia. Nonhematological toxicities consisted mainly of neurotoxicity and myalgias. A drop of 10%-20% in the left ventricular ejection fraction was detected in two patients and another patient had a decrease greater than 20%, although none developed symptoms of heart failure. Overall response rate was 80.4% (95% confidence interval: 68.3-92.5), with 15 patients (36.6%) achieving a complete response. Median survival time was 27 months and median time to progression was 15 months. The GAT combination is feasible and very active in patients with metastatic breast cancer, with an encouraging response rate including a high rate of complete responses. No congestive heart failure was documented and other toxicities were mild, with the exception of neutropenia.

Abstract
The sequential use of a doxorubicin combination followed by paclitaxel has been reported to improve disease-free and overall survival in patients with node-positive breast cancer beyond that obtained with doxorubicin/cyclophosphamide combinations. Epirubicin is associated with less cardiotoxicity than doxorubicin and can be used at cumulative dose levels or intensities that cannot be safely achieved with doxorubicin. Epirubicin/taxane combinations have exhibited significant activity when used in the treatment of metastatic breast cancer. Based on these safety and efficacy data, a phase III adjuvant trial will compare the efficacy of a concurrent epirubicin/taxane regimen with sequential epirubicin/cyclophosphamide followed by taxane treatment in patients with operable node-positive breast cancer.

Abstract
Clinical trial data indicate that epirubicin-based adjuvant treatment of breast cancer is associated with marked improvement in relapse-free and overall survival compared with traditional cyclophosphamide/methotrexate/5-fluorouracil. The outcomes are comparable to those achieved with sequential use of doxorubicin/cyclophosphamide and paclitaxel. Dose intensification of epirubicin is feasible, with tolerable side effects and no increased risk of cardiotoxicity beyond that expected. Clinical trial data coupled with pharmacokinetic evidence provide a strong foundation and rationale for current and future investigation of epirubicin in combination with the taxanes in the adjuvant setting. An ongoing German study is evaluating epirubicin/cyclophosphamide in combination with trastuzumab as first-line therapy of metastatic breast cancer in patients whose tumors overexpress HER2/neu protein. These results, particularly the tolerability of this regimen, will form the basis for future adjuvant and neoadjuvant studies of epirubicin/trastuzumab-based regimens.

Abstract
Anthracyclines were first introduced for the treatment of metastatic breast cancer in the 1970s and are still among the most active single agents for the treatment of this disease. Unfortunately, their clinical value is limited by late-onset ventricular dysfunction. Epirubicin, an anthracycline analogue, does not eliminate the risk of cardiotoxicity but is less cardiotoxic and myelotoxic than doxorubicin at equimolar doses, thereby allowing the safe administration of cumulative doses between 950 and 1000 mg/m2. The inclusion of epirubicin in combination regimens, such as fluorouracil/epirubicin/cyclophosphamide (FEC), has been shown to be safe and active as first-line treatment for metastatic breast cancer. In the past few years, new drugs, including taxanes, have shown a high level of activity as single agents in the treatment of advanced breast cancer. Doxorubicin/paclitaxel combinations have shown high overall response rates (90%) as first-line chemotherapy of advanced breast cancer; however, congestive heart failure has been reported in up to 20% of patients. Epirubicin/paclitaxel combinations have been associated with grade 3 cardiotoxicity (6%) in only one study. We report findings of a trial of combination epirubicin/paclitaxel as first-line treatment of advanced breast cancer, with overall response rates (ORRs) of 84% and a complete response (CR) rate of 19%. Achieving a CR to first-line chemotherapy for advanced breast cancer appears to predict survival, and adding an active drug with a different mechanism of action and nonoverlapping toxicity might increase the percentage of CRs. We therefore tested the feasibility and activity of 6 to 8 courses of first-line treatment with a three-drug combination (gemcitabine 1000 mg/m2 days 1 and 4, epirubicin 90 mg/m2 day 1, and paclitaxel 175 mg/ m2 over 3 hours on day 1) in a phase II study of 36 metastatic breast cancer patients. Treatment was well tolerated, with an ORR of 92% (95% confidence interval: 77.53%-98.25%) and a CR of 31%. In considering retreating patients who progress or relapse after receiving an anthracycline-/taxane-containing regimen with the same active drugs, epirubicin appears ideal in both the adjuvant and metastatic breast cancer settings.

Abstract
Initial trials of paclitaxel and doxorubicin in advanced breast cancer yielded high response rates but significant cardiac toxicity was observed. In this phase II trial we investigated the efficacy and safety of paclitaxel combined with epirubicin. Patients with advanced breast cancer, performance status 0-2, measurable disease, and a normal left ventricular ejection fraction, who may have received adjuvant chemotherapy were treated with epirubicin 75 mg m(-2) followed by a 3-h infusion of paclitaxel 175 mg m(-2) repeated every 3 weeks. Forty-three eligible patients were treated at six centres. 67% patients received the maximum of six cycles. The response rate was 54% (95% CI 38-69%), 12% CR and 42% PR. Estimated median progression-free survival was 6.9 months (95% CI 5.4-10.0) and estimated median overall survival was 17.9 months (95% CI 14.2-25.7). Four patients had a decrease in the left ventricular ejection fraction (LVEF) of > or =20% of baseline value, and in two patients the LVEF decreased to below the lower limit of normal, but no patient developed clinical evidence of cardiac failure. Grade 4 neutropenia occurred in 56% cycles, but only 4% of cycles were complicated by febrile neutropenia. Grade 3 or 4 non-haematologic toxicity was uncommon. In conclusion, paclitaxel 175 mg m(-2) and epirubicin 75 mg m(-2) is a well tolerated, promising regimen for the treatment of advanced breast cancer.

Abstract
BACKGROUND The combination of paclitaxel and epirubicin has shown a favorable interaction in patients with advanced breast carcinoma. Therefore the efficacy and toxicity of this regimen was evaluated in a Phase II study of patients with metastatic nonsmall cell lung carcinoma (NSCLC). METHODS Thirty-two chemotherapy-naive patients with AJCC Stage IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0-1 were entered into the study. Patients received epirubicin, 90 mg/m(2), followed by paclitaxel, 175 mg/m(2) by 3-hour infusion, on Day 1. The treatment was repeated every 3 weeks. Granulocyte-colony stimulating factor (G-CSF) was not used routinely. RESULTS A total of 116 treatment cycles was delivered. All patients could be assessed for response, toxicity, and survival. There were 16 partial responses and no complete responses, giving rise to an overall response rate of 50% (95% confidence interval, 31. 9-68.1%). The median time to progression in responders was 7 months. The median survival was 8 months, and the 1-year survival rate was 37%. World Health Organization Grade 4 neutropenia occurred in 69% of patients, but could be managed easily with G-CSF, which was used in 35% of cycles. Cumulative peripheral neuropathy was the main nonhematologic toxicity and was observed in 7 of 8 patients who received 6 treatment courses (Grade 2-3 in 3 cases) and in 6 of 11 patients who received 4 cycles (Grade 2 in 2 patients). One patient died shortly after the first course of chemotherapy from a ventricular arrhythmia. CONCLUSIONS The combination of paclitaxel and epirubicin was found to be effective and well tolerated in chemotherapy-naive patients with metastatic NSCLC and warrants further evaluation in a multicenter trial of a larger number of patients. Careful cardiac evaluation before treatment is indicated.

Abstract
PURPOSE It has been shown in vitro that both cisplatin and epirubicin increase the antitumor activity of paclitaxel. Weekly administration could give a substantial improvement in the therapeutic index of cisplatin and paclitaxel. This study was aimed at defining the antitumor activity of a weekly cisplatin-epirubicin-paclitaxel (PET) administration in locally advanced or metastatic breast cancer patients. PATIENTS AND METHODS Sixty-eight breast cancer patients with advanced disease, who had not received prior chemotherapy (except adjuvant), received weekly cisplatin 30 mg/sqm, paclitaxel 120 mg/sqm and epirubicin 50 mg/sqm plus G-CSF (day 3-5), for a maximum of 12 cycles. Thirty-five patients had stage IIIB and 33 stage IV disease (14 with visceral metastases). RESULTS All patients were evaluable for response on an intent to treat basis. Overall, 21 complete and 38 partial responses have been recorded for an 87% ORR (95% CI = 76-94%). Fourteen CRs and 19 PRs have been registered in the 35 patients with locally advanced disease for a 94% ORR (95% CI = 81-99%) while 7 CRs and 19 PRs were observed in the 33 patients with metastatic disease for a 79% ORR (95% CI-61-91%). Surgery was performed in 33/35 women with locally advanced disease. Four of these patients (11%) showed no invasive cancer on pathologic examination, and in an additional 8 patients tumor < 1 cm was found in the breast. Only 4/33 patients who underwent surgery relapsed. The projected one-year RFS was greater than 80%. At an 11-month median follow-up (range, 3-19), 11 patients had progressed and 5 had died among the 33 patients with metastatic disease, the median progression-free survival in this group being 14 months. Severe hematologic toxicity was uncommon, grade 3-4 neutropenia and thrombocytopenia occurring in 32% and 4% of patients, respectively. Only 2 episodes of neutropenic sepsis were registered. Packed red blood cell transfusions were required in 7 patients. Vomiting, diarrhoea, mucositis and skin toxicity were severe in 6%, 9%, 10%, and 9% of patients, respectively. Peripheral neuropathy was observed in 47% of patients. CONCLUSIONS The weekly PET administration is a well tolerated and very effective approach in advanced breast cancer patients. It can produce a 40% clinical complete response rate, with a more than 10% pCR rate in patients with T4 disease, and an about 80% ORR in those with distant metastases. A phase III trial comparing PET with a standard every 3 weeks epirubicin-taxol administration is underway.

Abstract
We investigated the role of 2-[18F]-fluorodeoxyglucose (FDG) positron emission tomography (PET) in the early evaluation of response to chemotherapy in metastatic breast cancer patients. Breast cancer patients who received an epirubicin/paclitaxel--containing regimen as first-line treatment for metastatic disease were included in this study. A PET study was performed within 1 week before the start of treatment, at day 8 after the first course, and at the end of the planned program of chemotherapy. Tumor response was determined clinically and radiographically every 2 courses of treatment. Thirteen patients with metastatic breast cancer who were referred for treatment protocols with gemcitabine/epirubicin/paclitaxel or epirubicin/paclitaxel chemotherapy regimens were included in this study. All metastatic sites were easily visualized on the baseline FDG-PET images, obtained 50 to 60 minutes after tracer injection. Nine patients who completed the planned courses of chemotherapy and the FDG-PET studies were available for analysis. In the six patients who achieved a response to treatment, median glucose standard uptake value (SUV) (semiquantitative analysis) was 7.65 (range, 3.4-12.3) at baseline, 5.7 (range, 2.8-7.6) at day 8 after the first course, and 1.2 (range, 0.99-1.3) at the end of the 6 planned courses of chemotherapy. Three patients who obtained a stable disease as best response had no significant decrease in tumor glucose SUV compared to baseline levels. Qualitative visual analysis in the six responding patients showed a decrease in delineation of tumor mass from background activity soon after the first course, while the nonresponding patients had no significant modification from basal levels. Semiquantitative FDG-PET scanning of metastatic breast cancer sites showed a rapid and significant decrease in tumor glucose metabolism soon after the first course of treatment in patients who achieved a response to first-line chemotherapy. On the contrary, no significant decrease was observed in nonresponding patients.
