Abstract
AIMS AND BACKGROUND Sequential docetaxel and gemcitabine following initial docetaxel plus epirubicin or vinorelbine association could be worthwhile as first-line treatment of metastatic breast cancer. METHODS Fifty-eight patients entered a phase II study that included two sequential phases. In the first phase, 36 and 22 patients previously unexposed or exposed to adjuvant anthracyclines received the association of docetaxel (75 mg/m2, day 1) with epirubicin (75 mg/m2, day 1) or vinorelbine (20 mg/m2, days 1 and 5), respectively, every 21 days for 4 courses. In the second phase, patients who had a response (R) or stable disease (SD) received docetaxel (35 mg/m2) and gemcitabine (800 mg/m2) on days 1, 8 and 15 every 28 days for 4 courses. RESULTS In the first phase, grade > or = III neutropenia occurred in 51% and 37% of patients during docetaxel-epirubicin and docetaxel-vinorelbine, respectively. In the second phase, it occurred in the 27% and 15% of patients initially treated with docetaxel-epirubicin and docetaxel-vinorelbine, respectively. On an intention to treat basis, the complete (CR) + partial response (PR) rate to the first phase was 71%, and 22% of patients had SD, without a significant difference between the docetaxel-epirubicin and docetaxel-vinorelbine arms. After the second phase, the CR + PR rate was 65%, and 14% of patients had SD. Median time to progression and survival were 12.1 and 22.0 months, respectively, without a significant difference between patients initially treated with docetaxel-epirubicin and docetaxel-vinorelbine. CONCLUSIONS Following an initial docetaxel-based treatment, weekly docetaxel and gemcitabine maintains high percentages of R and SD, with improved toxicity. Survival was similar in patients previously untreated and treated with adjuvant anthracyclines.

Revisiting dosing regimen using PK/PD modeling: the MODEL1 phase I/II trial of docetaxel plus epirubicin in metastatic breast cancer patients. Breast Cancer Res Treat 2016; 156:331-41. [PMID: 27002506 DOI: 10.1007/s10549-016-3760-9] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2016] [Accepted: 03/15/2016] [Indexed: 11/24/2022]
Abstract
The MODEL1 trial is the first model-driven phase I/II dose-escalation study of densified docetaxel plus epirubicin administration in metastatic breast cancer patients, a regimen previously known to induce unacceptable life-threatening toxicities. The primary objective was to determine the maximum tolerated dose of this densified regimen. Study of the efficacy was a secondary objective. Her2-negative, hormone-resistant metastatic breast cancer patients were treated with escalating doses of docetaxel plus epirubicin every 2 weeks for six cycles with granulocyte colony stimulating factor support. A total of 16 patients were treated with total doses ranging from 85 to 110 mg of docetaxel plus epirubicin per cycle. Dose escalation was controlled by a non-hematological toxicity model. Dose densification was guided by a model of neutrophil kinetics, able to optimize docetaxel plus epirubicin dosing with respect to pre-defined acceptable levels of hematological toxicity while ensuring maximal efficacy. The densified treatment was safe since hematological toxicity was much lower compared to previous findings, and other adverse events were consistent with those observed with this regimen. The maximal tolerated dose was 100 mg given every 2 weeks. The response rate was 45 %; median progression-free survival was 10.4 months, whereas 54.6 months of median overall survival was achieved. The optimized docetaxel plus epirubicin dosing regimen led to fewer toxicities associated with higher efficacy as compared with standard or empirical densified dosing. This study suggests that model-driven dosage adjustment can lead to improved efficacy-toxicity balance in patients with cancer when several anticancer drugs are combined.

[PMID: 24091128 DOI: 10.1016/j.breast.2013.08.017] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2012] [Revised: 07/01/2013] [Accepted: 08/29/2013] [Indexed: 12/21/2022] Open
Abstract
PURPOSE To assess the efficacy and toxicity of docetaxel (D) plus epirubicin (E) in combination with bevacizumab (B) [DEB regimen] as front-line treatment in patients with metastatic breast cancer (MBC). PATIENTS AND METHODS Women with previously untreated HER2-negative MBC received B (15 mg/kg), E (75 mg/m2) and D (75 mg/m2) with prophylactic G-CSF support every 3 weeks (q3w) for up to 9 cycles followed by B (15 mg/kg q3w) until disease progression. Primary endpoint was the overall response rate (ORR). Circulating tumor cells (CTCs) were evaluated using the CellSearch system at different time points during therapy. RESULTS Eighty-three women were enrolled with median age 62 years, performance status 0-1 in 93%, triple negative disease in 12% and liver metastases in 47%. In an intention to treat analysis, complete response was achieved in 13 (15.7%) and partial response in 42 (50.6%) (overall response rate 66.3%; 95% CI 56.09-76.44%). The median time to progression was 20.1 months and the 1-year overall survival rate 82.3%. Grade 3-4 neutropenia occurred in 37%, febrile neutropenia in 10%, anemia in 4%, thrombocytopenia in 2% and diarrhea in 2% of patients. There were two deaths possibly related to study treatment (sigmoid perforation n = 1; sudden death n = 1). Moreover, one patient developed pulmonary embolism and another one myocardial infarction while on treatment. Although DEB administration significantly reduced the proportion of patients presenting CTCs, the detection of ≥5 or ≥1 CTCs before treatment initiation was significantly associated with worse progression-free survival (p = 0.001 and p = 0.004) and overall survival (p = 0.001 and p = 0.027), respectively. CONCLUSIONS The DEB regimen is a very active but also potentially toxic combination in MBC. Detection of CTCs before treatment is associated with worse outcome. CLINICALTRIALSGOV NCT00705315.

Abstract
BACKGROUND We conducted a phase II study to evaluate the efficacy and toxicity of weekly docetaxel combined with epirubicin on D15 as second-line chemotherapy in Taiwanese patients with advanced non small cell lung cancer (NSCLC) who failed or relapsed after the frontline platinum-based chemotherapy. PATIENTS AND METHODS Patients with histologically confirmed advanced NSCLC (Stage IIIB-IV) were entered into this Phase II trial. Eastern Cooperative Oncology Group performance status was 0 to 2 and adequate organ function was required. Docetaxel, 30 mg/m, was given intravenously on days 1, 8, and 15 for 30 minutes and epirubicin, 60 mg/m, was given intravenously on day 15, then following one week of rest. Treatment was repeated every 4 weeks for a maximal total of 6 cycles. RESULTS Of the 43 eligible patients, 39 patients were evaluated for response, and all were evaluated for toxicity. The overall response rate was 11.6% [95% confidence interval (CI), 1.6-21.6%]. The median time to disease progression for all patients was 2.8 months (95% CI 1.3-4.3%). The median survival time for all patients was 7.7 months (95% CI 5.5-9.9%). The 1-year survival was 32.6% (95% CI 25.4%-39.7%). The major hematologic toxicities were neutropenia, 8/43 (19%) with grade 3-4 neutropenia, as well as anemia, 6/43 (14%) with grade 3-4 anemia. Nonhematological toxicities were modest. Fatigue was common, 77.8% in all, but only 3 (7%) patients with grade 3-4 toxicities. Diarrhea was also common but not severe, 7/43 (16%) with grade 1-2 episodes, and 1/43 (2%) with grade 3-4 episodes. Nail changes, peripheral edema, lacrimation, and alopecia were mild. Hepatic and renal impairment was also only mild. CONCLUSION Combining weekly doses of docetaxel 30 mg/m with epirubicin 60 mg/m on D15 was not shown to improve both efficacy and tolerability for advanced NSCLC patients who have relapsed disease after frontline platinum-based chemotherapy.

Abstract
BACKGROUND The purpose of this study was to compare docetaxel plus epirubicin versus docetaxel plus capecitabine combinations as front-line treatment in women with advanced breast cancer (ABC). PATIENTS AND METHODS Previously untreated patients with ABC were randomly assigned to receive docetaxel 75 mg/m(2) plus epirubicin 75 mg/m(2) (DE) on day 1 or docetaxel 75 mg/m(2) on day 1 plus capecitabine 950 mg/m(2) orally twice daily on days 1-14 (DC) in 21-day cycles. Previous anthracycline-based (neo)-adjuvant chemotherapy was allowed if completed >1 year before enrollment. The primary objective of the study was to compare time to disease progression (TTP). RESULTS One hundred and thirty-six women were treated on each arm and median TTP was 10.6 versus 11.0 months (P = 0.7), for DE and DC, respectively. According to RECIST criteria we observed 15 (11%) versus 11 (8%) complete responses and 55 (40%) versus 61 (45%) partial responses (P = 0.8), with DE and DC, respectively. Severe toxicity included grade 3-4 neutropenia (57% versus 46%; P = 0.07), febrile neutropenia (11% versus 8%; P = 0.4), hand-foot syndrome (0% versus 4%; P = 0.02), grade 2-3 anemia (20% versus 7%; P = 0.001) and asthenia (12% versus 6%; P = 0.09) with DE and DC, respectively. CONCLUSIONS The DE and DC regimens have similar efficacy but different toxicity. Either regimen can be used as front-line treatment of ABC.

Abstract
This multicentre phase II study was aimed at investigating the activity and safety of pegylated liposomal doxorubicin (PLD) and gemcitabine (GEM) as front-line therapy in a large series of chemotherapy-naïve recurrent/metastatic breast cancer patients. From June 2003 to December 2006, a total of 71 recurrent/metastatic breast cancer patients were enrolled. Median age was 63 years (range=37-79), and 31 patients (43.7%) were > or =65 years old. Patients received PLD, 25 mg m(-2), day 1, followed by GEM, 800 mg m(-2), days 1 and 8, q21. Response was evaluable in 64 cases. Eight complete (12.5%) and 17 partial responses (26.6%) were registered, with an overall response rate of 39.1%. Thirty patients (46.9%) experienced stable disease, with an overall clinical benefit of 85.9%. Median time to progression (TTP) was 11 months, whereas median overall survival (OS) was not reached. The rate of 1- and 2-year OS was 79 and 61%, respectively. A total of 443 courses were evaluable for toxicity: grade 3 and 4 neutropaenia affected 14 patients (20.3%) and 3 patients (4.3%), respectively. Grade 3 and 4 palmar-plantar erythrodysesthesia syndrome was documented in five cases (7.2%) and one case (1.4%), whereas grade 3 and 4 mucositis occurred in six cases (8.7%) and two cases (2.9%), respectively. Grade 2 cardiac toxicity was observed in only one case. Interestingly enough, there was no difference in the percentage and severity of either haematological or non-haematological toxicity according to the age of the patients (<65 vs > or =65 years). We confirmed in a large, very homogenous study sample of chemotherapy-naïve recurrent/metastatic breast cancer patients the efficacy and safety of PLD/GEM combination, providing response rates, median TTP and OS values comparable with those achieved with more toxic combinations.

Abstract
This study was designed to evaluate the efficacy and tolerability of a weekly schedule of epirubicin in combination with docetaxel in the first-line treatment of patients with metastatic breast cancer (MBC). A total of 43 women with MBC not previously treated with chemotherapy for metastatic disease received weekly epirubicin 25 mg m−2 and docetaxel 25 mg m−2 for a maximum of five cycles (total cumulative epirubicin dose of ⩽900 mg m−2). Dose reduction was not permitted. Objective response and evaluation of toxicity profile were the primary study end points; time to progression and overall survival were secondary end points. Patients were followed for a median of 21 (4–38) months. Analysis was by intent to treat; 33 patients completed five cycles of therapy, and the median dose of epirubicin administered to the 43 patients was 23 mg m−2. Twenty-five patients (58%) achieved a partial response and one (2%) achieved a complete response. An additional 12 patients (28%) had stable disease. The median time to progression was 11 months (95% confidence intervals (CI) 7–14) overall, and 13 months (95% CI 12–14) in the 26 patients who responded to treatment. Median overall survival was 25 months for responders and 14 months for nonresponders. Grade 3/4 neutropenia occurred in 16% of patients and in 6% of cycles. One patient developed cardiac toxicity (20% reduction in left ventricular ejection fraction). The combination of epirubicin plus docetaxel is highly active in MBC, with a manageable toxicity profile. Such a weekly schedule might provide a valuable treatment option for MBC.

Abstract
PURPOSE The PACS 01 trial compared six cycles of fluorouracil, epirubicin, and cyclophosphamide (FEC) with a sequential regimen of three cycles of FEC followed by three cycles of docetaxel (FEC-D) as adjuvant treatment for women with node-positive early breast cancer. PATIENTS AND METHODS Between June 1997 and March 2000, 1,999 patients with operable node-positive breast cancer were randomly assigned to either FEC every 21 days for six cycles, or three cycles of FEC followed by three cycles of docetaxel, both given every 21 days. Hormone-receptor-positive patients received tamoxifen for 5 years after chemotherapy. The primary end point was 5-year disease-free survival (DFS). RESULTS Median follow-up was 60 months. Five-year DFS rates were 73.2% with FEC and 78.4% with FEC-D (unadjusted P = .011; adjusted P = .012). Multivariate analysis adjusted for prognostic factors showed an 18% reduction in the relative risk of relapse with FEC-D. Five-year overall survival rates were 86.7% with FEC and 90.7% with FEC-D, demonstrating a 27% reduction in the relative risk of death (unadjusted P = .014; adjusted P = .017). The incidence of grade 3 to 4 neutropenia, the need for hematopoietic growth factor, and incidence of nausea/vomiting were higher with FEC. Docetaxel was associated with more febrile neutropenia in the fourth cycle, stomatitis, edema, and nail disorders. Though rare overall, there were fewer cardiac events after FEC-D (P = .03), attributable mainly to the lower anthracycline cumulative dose. CONCLUSION Sequential adjuvant chemotherapy with FEC followed by docetaxel significantly improves disease-free and overall survival in node-positive breast cancer patients and has a favorable safety profile.

Abstract
Among the novel chemotherapeutic agents introduced in the last decade, the taxanes have emerged as the most powerful group of compounds, and results available so far confirm that they will be remembered in the future as the breast cancer chemotherapy of the 1990s. Two taxanes are available (paclitaxel and docetaxel) and they share some characteristics, although they do have some significant differences both in terms of their preclinical profile and, most importantly, their clinical characteristics. There are three main clinical differences: different efficacy-toxicity ratio in relation to dose and schedule; different integrability in anthracycline- and taxane-containing regimens, secondary to differences in pharmacokinetic interactions with anthracyclines; and different level of synergism between each taxane and trastuzumab. In clinical practice, the taxanes are now standard therapy in metastatic breast cancer. Their role as monochemotherapy or in combination with anthracyclines in advanced breast cancer has suggested their potential therapeutic impact in the treatment of patients with early breast cancer. Recent results in the adjuvant setting show that taxanes, used either in combination or in sequential therapy, possess the capability to induce significant improvements, in particular in terms of survival; thus confirming the positive impact of taxanes on the natural history of breast cancer. However, further results of all completed or ongoing Phase III trials in the early setting will help define the optimal use of taxanes and maximise the induced benefits for breast cancer patients.

Abstract
The aim of the study was to demonstrate the superiority of docetaxel and epirubicin vs docetaxel alone as first-line therapy in metastatic breast cancer patients pretreated with adjuvant or neoadjuvant epirubicin. We compared single agent docetaxel 100 mg m-2 (D) with the combination of docetaxel 80 mg m-2 and epirubicin 75 mg m-2 (ED). The response rate (72 vs 79%), the progression-free survival (median 9 vs 11 months) and the overall survival (median 18 vs 21 months) were not significantly different between the ED (n=26) and D arms (n=25), respectively. Leucopaenia, nausea and stomatitis were significantly worse with ED. In conclusion, epirubicin should not be administered in combination with taxanes in metastatic breast cancer patients relapsed after an anthracycline-based adjuvant or neoadjuvant therapy.

Abstract
It has become clear over the past 10 years that docetaxel, a semisynthetic taxoid antineoplastic agent, is among the most promising compounds to have been developed in the 1990s for the treatment of breast cancer. Data indicate that this drug became standard therapy in the treatment of patients with metastatic disease who have failed anthracycline treatment, and secondarily showed very encouraging results in the first-line metastatic setting either in monochemotherapy or when docetaxel was combined with an anthracycline. More recently, docetaxel also became one of the standard therapies in the adjuvant and neoadjuvant settings, and a promising partner for novel biologic therapies. Current research is further exploring the effect of docetaxel on outcome of early breast cancer in order to fully determine the extent that this chemotherapeutic agent will change the natural history of breast cancer.

Abstract
Purpose The aims of the present study were (1) to characterize the pharmacokinetics of both component drugs and (2) to describe the relationship between the pharmacokinetics and the dose-limiting hematologic toxicity for the epirubicin (EPI)/docetaxel (DTX) regimen in breast cancer patients. Patients and Methods Forty-four patients with advanced disease received EPI and DTX every 3 weeks for up to nine cycles. The initial doses (EPI/DTX) were 75/70 mg/m2. Based on leukocyte (WBC) and platelet counts, the subsequent doses were, stepwise, either escalated (maximum, 120/100 mg/m2) or reduced (minimum, 40/50 mg/m2). Hematologic toxicity was monitored in all patients, whereas pharmacokinetics was studied in 16 patients. A semiphysiological model, including physiological parameters as well as drug-specific parameters, was used to describe the time course of WBC count following treatment. Results In the final pharmacokinetic model, interoccasion variability was estimated to be less than interindividual variability in the clearances for both drugs. The sum of the individual EPI and DTX areas under concentration-time curve correlated stronger to WBC survival fraction than did the corresponding sum of doses. A pharmacokinetic-pharmacodynamic (PK-PD) model with additive effects of EPI and DTX could adequately describe the data. Conclusion The final PK-PD model might provide a tool for calculation of WBC time course, and hence, for prediction of nadir day and duration of leukopenia in breast cancer patients treated with the EPI/DTX regimen.

Abstract
OBJECTIVE To evaluate the docetaxel-gemcitabine combination administered every 2 weeks in women with untreated metastatic breast cancer (MBC). METHODS Fifty-two patients with MBC received docetaxel 65 mg/m2 as front-line chemotherapy intravenously over 1 h followed by gemcitabine 1,500 mg/m2 intravenously over 30 min on days 1 and 14. Cycles were repeated every 28 days without prophylactic growth factor support. Twenty-eight (54%) patients had previously received chemotherapy as adjuvant or neoadjuvant treatment. Thirty-six (69%) patients had visceral disease including 20 (38%) with liver metastases. All patients were evaluated for toxicity and 45 for response. RESULTS In an intention-to-treat analysis, a complete response occurred in 7 (13%) patients and partial response in 24 (46%) for an overall response rate of 59% (95% CI: 46.3-73.0%). The response rate was 68% for the 28 patients who had previously received adjuvant or neoadjuvant chemotherapy and 67% for the 36 patients with visceral metastases. The median duration of response was 6.1 months and the median time to disease progression 10.9 months. A total of 254 cycles were administered with dose reduction in 26 (10%) cycles and no lethal toxicity. Grade III-IV neutropenia occurred in 17 (33%) patients and thrombocytopenia in 3 (6%). Febrile neutropenia developed in 3 (6%) patients. Nonhematological toxicity was generally mild. CONCLUSION The docetaxel-gemcitabine combination is an active and well-tolerated front-line treatment for patients with MBC. This regimen represents a suitable option especially for women relapsing after anthracycline-based adjuvant chemotherapy.

Abstract
The taxanes and anthracyclines have emerged as the most active agents for treating women with advanced breast cancer. As such, investigation of the two drug classes in combination regimens has been eagerly pursued. The rationale for combining docetaxel with an anthracycline includes high clinical activity of each individual agent, lack of complete clinical cross resistance, and non-overlapping toxicity profiles. Phase II trials of the docetaxel combinations with either doxorubicin or epirubicin showed high activity, with acceptable tolerability in patients with metastatic breast cancer. Consequently, three randomized trials have compared docetaxel-anthracycline-based regimens with standard anthracycline-based polychemotherapies as first-line therapy for women with advanced breast cancer. Improved outcome was reported in favor of the docetaxel-anthracycline combinations, with manageable hematologic toxicity and favorable non-hematologic safety profiles. Therefore, docetaxel-anthracycline combinations represent a validated option in first-line treatment for women with advanced breast cancer, and are further evaluated as adjuvant treatment for early stage breast cancer, with already promising prospects and the potential to change the natural history of breast cancer.

Abstract
PURPOSE In this multicentre phase II study, the efficacy and safety profile of the combination of docetaxel and epirubicin as first-line chemotherapy for metastatic breast cancer (MBC) were evaluated. METHODS Epirubicin (75 mg/m(2)) and docetaxel (75 mg/m(2)) were given intravenously once every 3 weeks for six cycles to 133 patients with MBC. RESULTS The overall clinical response rate was 67% (complete and partial responses were 23% and 44%, respectively). The median time to progression was 10.8 months (95% CI 9.7-12.6) and the median overall survival was 19.5 months. Granulocyte colony-stimulating factor support was administered to 32% of patients and in 22% of cycles. Grade 3/4 neutropenia occurred in 35% of patients and febrile neutropenia in 19%. The most frequent grade 3/4 non-haematological toxicities (as percent of patients) were asthenia (6%), vomiting (5%) and nausea (5%). No patients developed congestive heart failure. CONCLUSIONS The combination of docetaxel and epirubicin was highly active as first-line treatment for MBC and showed a manageable toxicity profile.

Abstract
BACKGROUND The objective of this study was to evaluate the activity and safety of oral capecitabine in combination with docetaxel and epirubicin (TEX) as first-line treatment for patients with locally advanced/metastatic breast carcinoma. METHODS This open-label, Phase II study was conducted at six Italian centers. Treatment consisted of epirubicin, 75 mg/m(2) (intravenous bolus), and docetaxel, 75 mg/m(2) (1-hour infusion), both administered on Day 1, plus oral capecitabine, 1000 mg/m(2) twice daily, on Days 1-14 of each 3-week treatment cycle. RESULTS A total of 67 patients received 392 cycles of treatment, with a median of 6 cycles in patients with Stage III disease (n = 34 patients) and a median of 8 cycles in patients with Stage IV disease (n = 33 patients). The objective response rate was 82%, including complete responses in 21% of patients. A greater proportion of patients with Stage III disease achieved tumor responses compared with patients who had Stage IV disease (97% vs. 67%, respectively). Among 34 patients with Stage III disease, pathologic complete responses were confirmed in 10 patients (29%). TEX chemotherapy demonstrated an acceptable safety profile. There was a low incidence of Grade 3 adverse events, and Grade 4 adverse events were particularly rare (4%). The most common Grade 3-4 adverse event was febrile neutropenia, which occurred in 16% of patients. CONCLUSIONS TEX combination therapy has important antitumor activity and an acceptable safety profile in this setting. A large, randomized, Phase III trial is ongoing to compare TEX chemotherapy with an epirubicin plus docetaxel regimen in patients with untreated, advanced breast carcinoma.

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 this investigation was to evaluate the efficacy and toxicity of 6 months' treatment with the combination of epirubicin and docetaxel in metastatic breast cancer. Thirty-eight women (mean age 51 years, range 35-72) with metastatic breast cancer were treated with a regimen of epirubicin 75 mg/m and docetaxel 75 mg/m every 3 weeks, given 4 times if progression was seen upon evaluation after 4 courses or 8 times in responding/stable patients. The patients received 285 cycles of combination treatment and two treatments with docetaxel or epirubicin alone. When neutropenia with fever was observed, further cycles were given with dose reduction. The median cumulative docetaxel dose was 462 mg/m (range 199-600) and that of epirubicin 476 mg/m (range 199-740). The overall response rate was 54% (95% CI 37-71), with a median duration of response of 14.8 months (95% CI 8.8-27.8). Median time to progression was 12 months, median survival 26 months. Neutropenia below 0.5 x 10 /l occurred following 113 (39%) of the total of 285 cycles given; 21 patients (55%) were hospitalized for febrile neutropenia. We conclude that dose tailoring is required in treatment with an epirubicin and docetaxel regimen to avoid grade 3/4 adverse effects in a significant number of patients treated for metastatic breast cancer.

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 Capecitabine is an oral fluoropyrimidine with considerable activity and minimal myelosuppression and alopecia. This phase I study evaluated the addition of capecitabine to epirubicin/docetaxel combination therapy as first-line treatment for advanced breast cancer. PATIENTS AND METHODS Twenty-three female patients with advanced breast cancer received capecitabine (765-1060 mg/m2 twice daily on days 1-14 of a 3-week treatment cycle) in combination with epirubicin and docetaxel (75 mg/m2 i.v. on day 1). RESULTS The maximum tolerated dose of capecitabine was 985 mg/m2 and the principal dose-limiting toxicity was febrile neutropenia. No grade 3/4 anemia or thrombocytopenia occurred. There were no grade 4 non-hematological events and grade 3 events other than alopecia were rare. Alopecia occurred in all patients and treatment cycles, and asthenia occurred in all patients and in 84% of treatment cycles. Other frequent adverse events included nausea, vomiting, fever, paresthesia and elevated transaminase levels. An objective response to treatment was observed in 91% (95% confidence interval 72% to 99%) of patients. CONCLUSIONS The addition of capecitabine to docetaxel/epirubicin combination therapy provides a well-tolerated and active first-line chemotherapy regimen in patients with advanced breast cancer, and merits phase II/III evaluation.

Abstract
Adjuvant treatment of early breast cancer has experienced major changes in the last 25 years. Since the mid 1970s, when cyclophosphamide, methotrexate and fluorouracil (CMF) resulted in statistically significant and clinically meaningful improvements in disease-free and overall survival, the use of adjuvant chemotherapy has become common practice worldwide. Anthracyclines are considered to be among the most active available agents to treat breast cancer and have become core components of adjuvant regimens. Anthracycline-containing polychemotherapy regimens provide a significant benefit over CMF. Regimens containing epirubicin are generally associated with prolongation in relapse-free and overall survival rates compared with standard therapies including CMF. Epirubicin-taxane combinations are active in treating metastatic breast cancer and do not appear to be associated with any pharmacokinetic interactions. Ongoing research is focusing on combining anthracyclines with taxanes in an effort to continue to improve outcomes following adjuvant therapy.

Abstract
Anthracyclines and taxanes are to date the most active cytotoxic agents in the treatment of breast cancer, and a combination of these is therefore considered to result in the highest response rates in the neoadjuvant, as well as in palliative treatment. These two phase II studies aimed to evaluate the feasibility, toxicity and activity of a cytostatic regimen combining epidoxorubicin and docetaxel in outpatient patients suffering from breast cancer. In total, 104 consecutive patients were enrolled in these prospective clinical trials. The chemotherapeutic regimen consisted of epidoxorubicin [75 mg/m2 body surface area (BSA)] and docetaxel (75 mg/m2 BSA) on day 1 accompanied by the administration of granulocyte colony stimulating factor on days 3-10, repeated every 3 weeks (ED+G). Sixty-six patients received ED+G as neoadjuvant and 38 patients as palliative treatment, respectively. Patients received a total of 566 cycles (median: 6 cycles, range: 2-11 cycles) of this therapeutic regimen. Outpatient ED+G was well tolerated. A major response to preoperative ED+G could be demonstrated in 54 of 66 patients (82%) and in 22 of 38 palliative treated patients (58%). We conclude that outpatient ED+G is safe in the neoadjuvant and palliative treatment of patients suffering from breast cancer by showing a favorable side effect and activity profile. Thus, this regimen can be considered for further clinical trials.

Abstract
A large body of data on systemic therapy has been presented and published in the past year, including new information on primary risk reduction, patient selection for adjuvant systemic therapy, and anthracycline-analogs. New data on ongoing adjuvant trials (including taxane studies), unpublished updates from the fourth Oxford Overview in September 2000, and provocative data on ovarian ablation were important features of the November 2000 National Institutes of Health Consensus Development Conference on Adjuvant Therapy for Breast Cancer. Important new data on anti-estrogen therapy, including aromatase inhibitors and pure antiestrogens, further expand the role of the oldest targeted breast cancer therapy. Trastuzumab and other novel compounds are being investigated as single-agents and in combination with conventional systemic approaches. Discussions on the long-term effects of adjuvant therapy have taken center stage also. These and other important ongoing developments since 2000 are examined in this review article.
