Abstract
INTRODUCTION Docetaxel can cause fluid retention reactions (FRRs) and hypersensitivity reactions (HSRs). The manufacturer recommends a multi-day oral dexamethasone premedication to prevent these toxicities, but steroid related side effects and regimen compliance remain a concern. This study aimed to determine if modified dexamethasone premedication regimens resulted in differences in HSRs or FRRs to docetaxel. We also examined side effects of dexamethasone and delays in chemotherapy. METHODS A retrospective chart review was conducted on 82 early breast cancer patients treated with docetaxel. Three steroid regimens were examined: IV 20 mg single-dose dexamethasone, or IV 12 mg dexamethasone with either dexamethasone 8 mg BID for three days starting the day before chemotherapy or dexamethasone 4 mg BID for three days following chemotherapy. Adverse effects, delays in chemotherapy, and reasons for delays in chemotherapy were recorded. RESULTS The incidence and severity of FRRs and HSRs was low, with less than 10% incidence of HSRs or FRRs in any group. Delays were most common in the group receiving dexamethasone 8 mg BID for 3 days starting the day before chemotherapy (63.3%) (p < 0.05) and were most commonly due to patient noncompliance (26%). CONCLUSION A single dose of intravenous dexamethasone alone or followed by lower doses of oral dexamethasone may improve patient compliance and avoid delays in chemotherapy, without an increase in docetaxel toxicity.

Abstract
Objective. To summarize the systematic development of docetaxel as a new and effective treatment option for advanced non-small cell lung cancer (NSCLC) and breast cancer patients, and to discuss the physical and chemical stability, compatibility with drugs commonly used in cancer patients, and administration issues with the new docetaxel formulation. Data Sources. A MEDLINE search was conducted using carboplatin, cisplatin, compatibility, docetaxel, doxorubicin, metastatic breast cancer (MBC), NSCLC, and stability as search terms. Reference lists, bibliographies of pertinent articles, and abstracts from the American Society of Clinical Oncology and the European Society for Medical Oncology annual meetings were also identified and reviewed. Information related to the new docetaxel formulation was obtained from the manufacturer. The clinical literature was reviewed and analyzed. Data Synthesis. Docetaxel has recently emerged as an active agent in the treatment of advanced NSCLC and MBC. Results of phase II and III studies of single-agent docetaxel and docetaxel combinations, both as first- and second-line therapy, have produced impressive response rates and improved survival times compared with current standards of care. Docetaxel has a unique toxicity profile that includes hypersensitivity reactions, skin toxicities, and fluid retention. Because docetaxel's toxicity profile differs from that of the platinum analogs and the anthracyclines, combinations with these agents for NSCLC and MBC are well tolerated. Docetaxel was recently reformulated, allowing for improved stability, shelf-life, and storage requirements. Compatibility studies of docetaxel with 81 commonly used drugs in cancer patients were recently reported, showing that docetaxel is compatible with all but three drugs studied—amphotericin B, nalbuphine hydrochloride, and methylprednisolone sodium succinate—when administered as Y-site injections into existing intravenous lines. With the increasing use of this agent, the new docetaxel formulation and compatibility data should facilitate ease of administration.

Abstract
SUMMARY The taxanes, paclitaxel, docetaxel and nab-paclitaxel, are among the most active cytotoxic agents for treatment of breast cancer. Significant progress has been made in addressing taxane dose and schedule in both early-stage and metastatic disease. Several studies have clarified the role of retreatment with taxanes in recurrent breast cancer patients previously treated with taxane-containing regimens. In addition, the advent of nab-paclitaxel, designed to reduce allergic reactions and enhance drug delivery to tumor cells, has provided additional therapeutic options. This article summarizes the uses of taxanes in the treatment of metastatic breast cancer.

Abstract
BACKGROUND Ethnic differences in drug susceptibility and toxicity are a major concern, not only in drug development but also in the clinical setting. We review the toxicity profiles of docetaxel according to dose and ethnicity. METHODS We analyzed phase II and III clinical trials that included a once-every-3-weeks single-agent docetaxel arm. Logistic regression analysis was applied to identify the significant variables affecting the reported incidence of docetaxel-induced severe neutropenia. RESULTS Multivariate logistic regression analysis identified studies conducted in Asia [odds ratio (OR) 19.0; 95% confidence interval (95% CI) 3.64-99.0] and docetaxel dose (OR 1.08; 95% CI 1.03-1.13) as independent variables for the incidence of grade 3/4 neutropenia. CONCLUSIONS There is a significant difference in the incidence of docetaxel-induced severe neutropenia between Asian and non-Asian clinical studies. Physicians and pharmacists should consider ethnic diversity in docetaxel toxicity when interpreting the results of clinical trials.

Abstract
INTRODUCTION Addition of the antiangiogenic agent bevacizumab to paclitaxel significantly improves response rates and progression-free survival for metastatic breast cancer (MBC). To assess the activity of docetaxel plus bevacizumab, a multicenter phase II trial was conducted. PATIENTS AND METHODS Patients with measurable first-line HER2/neu-negative MBC were eligible. This trial began as a 2-arm study with a docetaxel-alone arm. When bevacizumab became widely available, it was converted to a 1-arm open-label trial of docetaxel/bevacizumab. Patients enrolled in the docetaxel-alone arm were permitted to cross over to docetaxel/bevacizumab. Patients received bevacizumab 15 mg/kg and docetaxel 75 mg/m2 intravenously (I.V.) every 3 weeks until disease progression, unacceptable toxicity, or consent withdrawal. RESULTS From March 2005 to September 2006, 76 patients were enrolled. Of the 7 patients who were randomized to docetaxel alone, 6 crossed over to docetaxel/bevacizumab (included in the safety analysis only). Two patients were found to be ineligible before receiving drug. Efficacy data are based on the 67 patients who were originally enrolled in the docetaxel/bevacizumab arm and received at least 1 dose of study medication. The confirmed objective response rate is 51% (34 of 67) with 9% complete responses (6 of 67) and 42% partial responses (28 of 67). Nine additional patients (13%) had stable disease lasting >or= 6 months. With a median follow-up of 21.7 months, the median time to progression is 9.3 months, and median overall survival is 26.3 months. Common grade 3/4 adverse events included neutropenia (33%), leukopenia/lymphopenia (25%), fatigue (22%), infection (17%), pain (16%), and hypertension (9%). CONCLUSION Docetaxel/bevacizumab was generally well tolerated with manageable toxicity and promising efficacy results.

Abstract
BACKGROUND Paclitaxel and docetaxel are considered fundamental drugs in the treatment of breast cancer. OBJECTIVES To review the current role of taxanes in the treatment breast cancer, with emphasis on data from randomized trials comparing the two taxanes. METHODS We have reviewed the available evidence in the literature to gauge the results of therapy of early and advanced breast cancer with taxanes. RESULTS Clinically benefits were first shown in metastatic setting. More recently, benefits have also been seen in the therapy of early-stage disease. It seems reasonable to consider either drug as standard treatment for node-positive early stage or metastatic breast cancer. Future studies should explore the optimal way of combining taxanes with novel biological and cytotoxic drugs. CONCLUSION Based on existing evidence, clinicians should choose a taxane-based regimen for their patients, according to clinical activity, toxicity profile, pharmacokinetics, and a dosing schedule that best meets the therapeutic needs and convenience.

Abstract
Taxanes (paclitaxel and docetaxel) comprise a class of mitotic inhibitors which considered highly active chemotherapeutic agents against cancer cells, and have become a cornerstone in the treatment of patients with early and advanced breast cancer. Following the initial generation of trials conducted to prove their efficacy, investigators turned to explore which taxane is superior in terms of efficacy, side effects, and quality of life based on head-to-head comparisons of paclitaxel versus docetaxel containing regimens. Moreover, many trials conducted to evaluate the optimal taxane dosing and schedule. This commentary discusses the ERASME 3 trial which compared the quality of life after four courses of doxorubicin combination with either paclitaxel or docetaxel, and also, it reviews all trials compared paclitaxel to docetaxel in both early and metastatic disease settings, in terms of efficacy, dosing, schedule, and toxicity profile.

Abstract
The combination of docetaxel and cisplatin has shown promising results in anthracycline-pretreated patients with advanced breast cancer, but with substantial toxicity. The efficacy and safety in anthracycline-naive patients has not been evaluated. Between October 2003 and January 2006, we enrolled 39 patients. None had undergone chemotherapy for metastatic disease or been exposure to adjuvant anthracycline-based regimens earlier. Eligibility criteria included: histologically proven metastatic cancer; WHO performance status (PS) 0-2; and adequate hematological, hepatic and renal function. Docetaxel (70 mg/m) and cisplatin (50 mg/m) were administered every 3 weeks until the patient either refused to continue, or progression, or even unacceptable toxicity occurred. Tumor response was assessed every three cycles. One patient was withdrawn from response analysis because of toxicity. Thirty-eight patients had a complete tumor assessment. Median age was 50 years (range, 28-63); 5.1% had a WHO of PS of 0; 87% a PS of 1; 7.7% a PS of 2; in 69%, two or more organs were involved. A total of 291 cycles (range, 1-9) were administered. Three complete responses and 27 partial responses (intent-to-treat response rate 30/39=76.9%) resulted; disease remained stable in six patients and two had disease progression. Grade III/IV toxicities included diarrhea in 10.2%, asthenia/fatigue in 2.5%, mucositis in 5.1% and neutropenia in 87.3% of patients. Seven patients developed febrile neutropenia (17.9%). The median time to progression was 11.2 months; the timespan was not sufficient to track the median survival. Docetaxel/cisplatin is an active regimen with acceptable toxicity in the first-line treatment of metastatic breast cancer, but it is not sufficiently promising as a standard. Further randomized study is warranted.

Abstract
The efficacy and tolerability of docetaxel 100 mg/m(2) every 3 weeks as second-line chemotherapy in patients with metastatic breast cancer was investigated. In addition, the efficacy of a 3-day prophylaxis against cumulative dose-related fluid retention was examined with methylprednisolone 32 mg twice daily for 3 days starting 12 and 3 h before the docetaxel infusion together with oral cetirizine 10 mg 12 and 3 h before start of docetaxel for prevention of acute hypersensitivity reactions. According to the intent to treat-analysis 35% (95%CI: 25; 46) of the 94 patients entered responded to therapy. Their median survival was 12 months (range 0-20 months). The respective response rate for the 87 patients eligible for response evaluation was 37% (95%CI: 27; 48). Their median duration of response was 8 months (range 3-12 months), their median time to progression was 4 months (range 1-12 months). The corresponding response rate in the eligible patient cohort with anthracycline-resistant disease was 28% (95%CI: 15; 45) and increased to 44% (95%CI: 30; 59) in the cohort with non-anthracycline-resistant disease. Patients with visceral metastases responded in 36% and patients with > or = 3 organs involved in 33%. In a retrospective analysis, the 3-day premedication of corticosteroids and antihistamines proved to be as effective as the established but more toxic 5-day regimen in delaying and preventing the occurrence of docetaxel derived toxicities especially the cumulative fluid retention. In conclusion, docetaxel represents one of the most active agents for second-line treatment of metastatic breast cancer, especially for anthracycline-resistant patients. Due to comparable effectiveness of the 5-day regimen which is widely used by others and the 3-day premedication tested in this trial the latter proved to be more favourable and was therefore recommended for future therapies.

Abstract
We report a 71-year male with castration-resistant metastatic prostate cancer who was treated with weekly docetaxel for 12 weeks and developed significant eye irritation and dryness during treatment. Subsequently, the patient presented with a lower eyelid mass, which on excision was demonstrated to be a chalazion. Docetaxel induced Meibomian duct inflammation and blockage is the likely cause of this presentation in a patient with no history of eyelid masses in the past.

Abstract
The microtubule-targeting agents have made significant contributions to cancer therapy over the past 50 years. The vinca alkaloids and taxanes have been used to treat a broad range of malignancies, including leukemias and lymphomas and many types of solid tumors. The taxanes have been frequently used in the treatment of advanced ovarian, breast, lung, head and neck, and prostate cancer, and they are increasingly being used in early stage disease. This chapter reviews the pharmacology, clinical indications, and toxicities associated with the vinca alkaloids and taxanes.

Abstract
PURPOSE Preoperative chemotherapy in patients with primary breast cancer treated with anthracyclines and taxanes results in high response rates, allowing breast conserving surgery (BCS) in patients primarily not suitable for this procedure. Pathological responses are important prognostic parameters for progression free and overall survival. We questioned the impact of histologic type invasive ductal carcinoma (IDC) versus invasive lobular carcinoma (ILC) on response to primary chemotherapy. PATIENTS AND METHODS 161 patients with breast cancer received preoperative chemotherapy consisted of epidoxorubicin 75 mg/m(2) and docetaxel 75 mg/m(2) administered in combination with granulocyte-colony stimulating factor (G-CSF) on days 3-10 (ED + G). Pathological complete response (pCR), biological markers and type of surgery as well as progression free and overall survival were compared between IDC and ILC. RESULTS Out of 161 patients, 124 patients presented with IDC and 37 with ILC. Patients with ILC were less likely to have a pCR (3% vs. 20%, P < 0.009) and breast conserving surgeries (51% vs. 79%, P < 0.001). Patients with ILC tended to have oestrogen receptor positive tumors (86% vs. 52%, P < 0.0001), HER 2 negative tumors (69% vs. 84%), and lower nuclear grade (nuclear grade 3, 16% vs. 46%, P < 0.001). Patients with ILC tended to have longer time to progression (TTP) (42 months vs. 26 months) and overall survival (69 months vs. 65 months). CONCLUSIONS Our results indicate that patients with ILC achieved a lower pCR rate and ineligibility for BCS to preoperative chemotherapy, but this did not result in a survival disadvantage. Because of these results new strategies to achieve a pCR are warranted.

Abstract
BACKGROUND The objective of this phase I study was to determine the maximal tolerated dose (MTD) of the combination of weekly docetaxel and exisulind in patients with advanced solid tumors. PATIENTS AND METHODS Patients with advanced or refractory solid tumors were treated with intravenous weekly docetaxel with daily oral exisulind. The following dose levels (docetaxel/exisulind) were explored: 30-mg/m2/200 mg po bid, 35/200, 35/250 and 40/250. Docetaxel was administered weekly for 6 weeks followed by 2 weeks off, and exisulind was taken twice daily. Each cycle was 8 weeks. RESULTS Eighteen patients were enrolled in the study. All of them had received prior systemic therapy. Most patients had either melanoma or carcinomas of the upper gastrointestinal tract. A total of 31 cycles of therapy were administered. DLTs were grade 3 diarrhea, anorexia and fatigue and grade 3 cutaneous toxicity at dose level 4 (40/250). Myelosuppression was mild. Fatigue and gastrointestinal toxicity (anorexia, dyspepsia, nausea, abdominal pain and diarrhea) represented the most common toxicities. However, grade 3 and grade 4 toxicities were uncommon. There were no treatment related deaths. No objective responses were observed and five patients achieved stable disease. CONCLUSIONS The recommended dose for phase II studies is weekly docetaxel 35 mg/m2 for 6 weeks followed by 2 weeks off in combination with oral exisulind 250 mg po bid. This combination is feasible and well-tolerated at these doses.

Abstract
The objective of this pilot trial was to evaluate the safety and activity profile of epidoxorubicin, docetaxel and oral capecitabine plus pegfilgrastim (TEX+P) as preoperative first-line treatment for patients with breast cancer. Eleven consecutive patients were enrolled in this prospective clinical pilot trial. Preoperative treatment consisted of epidoxorubicin [75 mg/m2 body surface area (BSA)] and docetaxel (75 mg/m2 BSA) administered sequentially on day 1 in combination with oral capecitabine 2000 mg/m2 daily divided into two doses on days 1-14 of each 3-week treatment cycle. Pegfilgrastim 6 mg fixed dose was administered s.c. on day 2 of every treatment cycle. Patients received a total of 58 cycles (median 6 cycles, range 1-6) of this therapeutic regimen. Outpatient TEX+P was well tolerated. No WHO grade IV toxicity was observed. A pathological major response to this preoperative therapy regimen could be demonstrated in eight of nine evaluable patients leading to breast-conserving surgery in seven of nine evaluable patients. We conclude that outpatient TEX+P is safe in the neoadjuvant treatment of patients with primary breast cancer. Thus, this regimen can be considered for further clinical trials.

Abstract
The purpose of this study was to evaluate the efficacy and tolerance of combined treatment with docetaxel-cisplatin as first-line chemotherapy in patients with metastatic breast cancer (MBC). Consecutive eligible chemonaive patients received docetaxel 75 mg/m(2) on day 1 and cisplatin 75 mg/m(2) on day 2 every 3 weeks for 6 cycles, with prophylactic recombinant human granulocyte colony-stimulating factor (rHuG-CSF) on days 4-11. Thirty-two patients (64%) had received prior adjuvant chemotherapy; these included 16 (32%) who had received anthracyclines. In 50 evaluable patients with a median age (range) of 56 (31-72) years, the overall response rate was 68% (95% CI, 55-81%), with 7 (14%) complete and 27 (54%) partial responses. Stable and progressive disease was observed in 10 (20%), and 6 (12%) patients, respectively. The median duration of response was 10 months, and the median time to progression was 39 weeks. Grade 3/4 hematological toxicity included--neutropenia in 9 patients (18%), anemia in 2 (4%) and thrombocytopenia in 1 (2%). One patient (2%) with febrile neutropenia required hospitalization. Grade 3/4 nonhematological toxicities included nausea/vomiting in 18%, nephrotoxicity in 14%, asthenia (4%), and neurotoxicity (2%). Toxicity was common in older patients (>56 years). There were no treatment-related deaths. A combination of docetaxel-cisplatin with rHuG-CSF support is well tolerated and effective as first-line chemotherapy in MBC.

Abstract
PURPOSE To compare the clinical and pathologic response rates of doxorubicin and cyclophosphamide (AC) with doxorubicin and docetaxel (AD) as primary chemotherapy in women with primary or locally advanced breast cancer. PATIENTS AND METHODS Eligible patients with histologically proven breast cancer with primary tumors >/= 3 cm, inflammatory or locally advanced disease, and no evidence of metastases were randomly assigned to receive a maximum of six cycles of either doxorubicin (60 mg/m(2)) plus cyclophosphamide (600 mg/m(2)) administered intravenously (IV) every 3 weeks or doxorubicin (60 mg/m(2)) plus docetaxel (75 mg/m(2)) IV every 3 weeks, followed by surgery on completion of chemotherapy. Results A total of 363 patients were randomly assigned to AC (n = 180) or AD (n = 183). A complete clinical response was observed in 17% and 20% of patients treated with AC and AD, respectively (P = .42). Overall (complete and partial) clinical response rates for AC and AD were 61% and 70%, respectively (P = .06). There was no significant difference in either the pathologic complete response rates in the breast with AC (24%) and AD (21%; P = .61) or in the number of patients with positive axillary nodes at surgery with AC (61%) and AD (66%; P = .28). At a median follow-up of 32 months, there is no significant difference between the two groups for the number of relapses. CONCLUSION In contrast to the positive results reported for sequential docetaxel after AC as primary chemotherapy of breast cancer, our data do not suggest a benefit for simultaneous AD over AC.

Abstract
PURPOSE This is a phase II study where a novel chemotherapy combination was tested in pre-treated breast cancer patients: docetaxel and irinotecan have already been established as agents for breast and colorectal cancer, respectively. METHODS Forty-eight (median age 54 years, range 26-77 year) patients, all evaluable, were enrolled. All patients had been pre-treated with anthracycline-combined chemotherapy, 30 of whom were also treated with paclitaxel and 2 with docetaxel. World Health Organization (WHO) performance status was 0-2. The dominant metastasis was in the liver (54.17%), in the lungs (27.08%), in soft tissues (12.50%) and in the skeleton (6.25%). Treatment involved irinotecan infusion 200 mg/m(2) for 90 min and docetaxel infusion 80 mg/m(2) for 90 min, repeated once every 3 weeks. RESULTS Twenty-five (52.08%, 95% confidence interval [CI] 37.95-66.21) patients showed responses: 3 complete (6.25%, 95% CI 0-13.05) and 22 (45.83%, 95% CI 31.74-59.92) partial; the most responsive metastases were observed at the liver site (53.85%). Grade 3 and 4 neutropenia was observed in 18 patients (37.50%); 14 (29.17%) patients developed anaemia and three (6.25%), thrombocytopenia. Concerning non-haematologic toxicity, alopecia and fatigue were common; grade 3 diarrhea was observed in only one (2.08%) patient. CONCLUSION The irinotecan-docetaxel combination produces quite a high response rate in pre-treated advanced breast cancer patients.

Abstract
BACKGROUND Docetaxel and irinotecan are synergistic agents with a broad spectrum of activity but overlapping myelosuppression. The study was designed to maintain dose intensity while limiting myelosuppression. The objectives of this study were to determine the maximal tolerated dose (MTD) of the combination of docetaxel and irinotecan administered weekly for four consecutive weeks every 42 days, to describe toxicities of this regimen, and to perform a pharmacokinetic analysis to evaluate changes in drug disposition as a function of dose as well as repeated dosing. METHODS Adult patients with advanced solid tumors were treated with docetaxel followed by irinotecan. Doses of 30/50, 35/50, 35/66, 30/57, 30/65, 30/80 mg/m(2), respectively, were studied. Pharmacokinetics of docetaxel, irinotecan and SN-38 in plasma were determined on days 1 and 22 by a high-performance liquid chromatography (HPLC) assay. RESULTS A total of 35 patients were treated. The MTD was docetaxel 30 mg/m(2) plus irinotecan 65 mg/m(2). Diarrhea was the dose-limiting toxicity; myelosuppression and other non-hematological toxicities were uncommon and mild. There were no significant differences in pharmacokinetic parameters between day 1 and day 22 (n=20). Five objective responses (breast, stomach and unknown primary) were observed among 30 evaluable patients. In addition, eight patients achieved stable disease. CONCLUSIONS The combination of weekly docetaxel and irinotecan is a well tolerated regimen and should be explored in phase II trials. This schedule maintains dose intensity and has limited myelosuppression.

Abstract
BACKGROUND Docetaxel is one of the most effective antitumor agents currently available for the treatment of metastatic breast cancer (MBC). This phase II multicenter study prospectively analyzed the efficacy and toxicity of docetaxel given on a weekly schedule as first-line treatment of metastatic breast cancer. PATIENTS AND METHODS All patients received docetaxel, 35 mg/m(2) weekly for 6 weeks, followed by 2 weeks of rest. Subsequent cycles (3 weeks of treatment, 2 weeks of rest) were given until a maximum of 5 cycles or disease progression. Premedication consisted of 8 mg dexamethasone intravenously 30 min prior to the infusion of docetaxel. RESULTS Fifty-four patients at a median age of 58 years with previously untreated MBC were included in the study. A median of 10 doses (median cumulative dose 339 mg/m(2)) was administered (range: 2-18). The overall response rate was 48.1% (95% CI: 34-61%, intent-to-treat). Median survival was 15.8 months and median time to progression was 5.9 months (intent-to-treat). Hematological toxicity was mild with absence of neutropenia-related complications. Grade 3 neutropenia was observed in 3.7% of patients and grade 3 and 4 anemia was observed in 5.6 and 1.9% of patients, respectively. CONCLUSION The weekly administration of docetaxel is highly efficient and safe as first-line treatment for MBC and may serve as an important treatment option specifically in elderly patients and patients with a reduced performance status.

Abstract
Breast cancer is the most common malignancy in women, accounting for about 18% of female cancers, and over half a million new cases are diagnosed worldwide each year. Its incidence increases with age and is currently rising. Although the increased availability of screening programs has allowed earlier detection and treatment of primary breast cancers, many patients relapse with metastases after apparently successful treatment of their primary tumor and over 15,000 women in the UK and about 50,000 in the USA die from advanced disease each year. The natural course of breast cancer is very variable even after the development of metastases, and depends on a variety of tumor characteristics and prognostic factors. This is reflected in the large number of treatments currently employed. However, despite this wide choice and considerable research over the years, treatment of metastatic breast cancer (MBC) prolongs average survival times only slightly. Current therapy is aimed at achieving a balance between producing maximal tumor shrinkage to produce the most effective possible palliation of symptoms, and minimizing adverse effects. Anticancer chemotherapy is the preferred option in patients who do not respond to hormones, those with hormone-independent tumors, those with aggressive breast cancer subtypes. A variety of anticancer chemotherapy regimens, using both single and combined agents, have been shown to be effective in achieving tumor regression in MBC. Anthracyclines (doxorubicin, epirubicin) are the most active of the established monotherapies, typically producing response rates of 50-60% during initial (first-line) treatment for metastatic disease, but being effective in fewer than 25% of patients requiring second-line therapy. The drawbacks of anthracyclines include dose-limiting cumulative cardiotoxicity and the development of resistant tumor clones after the use of anthracyclines for adjuvant or first-line therapy, especially if subsequent courses are required within a year. The success of these established chemotherapeutic agents depends greatly on the number and location of metastatic sites. Lymph node and soft tissue secondaries tend to respond well, while visceral metastases (especially in the liver) carry a particularly poor prognosis despite treatment. The outlook for patients with metastases involving more than two organ systems is also bleak. Although some patients can live for years with metastatic disease, the average survival time in patients with MBC is 18-24 months, while in those with liver metastases, life expectancy averages only 6 months. High-dose anticancer chemotherapy with granulocyte-colony stimulating factor (G-CSF) or autologous bone marrow transplantation has allowed the dose intensity of anthracyclines to be increased, and has improved the response rate to about 70% in selected patients with MBC. However, this approach has not been proven to improve survival, involves the risk of greater toxicity and drug-related mortality, and patients with reduced clearance of anthracyclines due to hepatic dysfunction from liver metastases may not be suitable candidates. A number of new anticancer agents have also recently been introduced in an attempt to improve on the performance and avoid the tolerability problems associated with anthracyclines. Among these, antitubulin agents (taxoids and vinorelbine) have shown highly promising activity in MBC. This paper reviews the preclinical, phase I and phase II data for one taxoid, docetaxel. Docetaxel (Taxotere) belongs to the taxoid class of cytotoxic agents, the development of which began more than 20 years ago. In 1971, paclitaxel (Taxol) was identified as the active compound of the crude extract of the bark of the Pacific Yew tree Taxus brevifolia. However, at that time the development of paclitaxel was hampered because of the limited source of the drug and difficulties with isolation, extraction and formulation. The second active taxoid, docetaxel, was isolated by Potier et al. in 1986. Docetaxel is prepared from a non-cytotoxic precursor, extracted from the needles of the European Yew tree Taxus baccata, that is condensed with a chemically-synthesized side-chain. As the docetaxel precursor is freely available because of the regenerating capacity of the needles the development of docetaxel has thus been rapid.

Abstract
PURPOSE Docetaxel is an active agent as first-line chemotherapy in patients with advanced breast cancer at a dosage of 100 mg/m2. However, the efficacy of this agent as a first-line drug when used at a lower dosage is unclear. This study was performed to evaluate the clinical efficacy and safety of 60 mg/m2 docetaxel for the treatment of breast cancer. PATIENTS AND METHODS This study enrolled 23 patients with advanced and/or metastatic breast cancer, who had not been treated with an anthracycline or taxane previously. Treatment with docetaxel was continued in patients showing a response until there was evidence of disease progression or unacceptable toxicity. RESULTS Among 20 fully evaluated patients, the overall response rate was 50.0% and the median time to progression was 31 weeks. The most commonly observed adverse events were neutropenia (78.2%) and fatigue (60.9%). Fluid retention occurred in only 8.7% of the patients. Adverse events did not cause discontinuation of the treatment. CONCLUSION Docetaxel achieved good disease control with mild adverse events in first-line treatment at a dosage of 60 mg/m2.

Abstract
Advances in breast cancer continue to focus on the development of novel agents as well as the development of novel combinations, with the major therapeutic goal of treatment strategies revolving around improving response rates, delaying the time to disease progression, palliating symptoms, and improving quality of life. The taxanes are recognized as some of the most active single agents in breast cancer and demonstrate remarkable activity with manageable toxicity in combination with gemcitabine. Gemcitabine, a novel S-phase specific cytidine nucleoside analogue of deoxycytidine, has broad antitumor activity with significant monotherapy activity in breast cancer, with response rates ranging from 22% to 42% depending on the pretreatment characteristics of the patients. In general, gemcitabine s favorable single-agent activity and novel mechanism of action, in addition to its largely nonoverlapping toxicities, have facilitated its further development in combination with a variety of chemotherapy agents, including the taxanes. Several phase I and II trials have reported impressive activity for the gemcitabine/taxane doublet with the suggestion of clinical synergism between these 2 classes of agents. Given the remarkable and durable activity reported for this doublet, subsequent phase II trials have focused on optimizing doses and schedules. Unmistakably, these trial results are clear improvements over the single-agent activity of the taxanes in metastatic breast cancer, with the recently reported phase III trial comparing gemcitabine plus paclitaxel versus paclitaxel alone clearly reinforcing the superior outcomes demonstrated for the combination. Either as a single agent or in combination with the taxanes, gemcitabine remains a rational choice for the treatment of breast cancer.

Abstract
A 45-year-old woman underwent a modified radical mastectomy for right breast cancer in July 1996. As lymph node metastases were quite advanced, chemotherapy was started with anthracyclines. Four years after surgery, cough and dyspnea appeared. Chest radiograph and CT showed reticular shadows bilaterally and slight pleural effusion, suggesting lymphangitic lung metastasis of breast cancer. Biweekly intravenous docetaxel (TXT,45 mg/m2) was initiated. Four courses of TXT ameliorated her complaints and radiographic findings. A total of 30 continuous courses of TXT suppressed disease exacerbation for 18 months until new lesions manifested in January 2002. The main side effects were grade 2 leukopenia and alopecia. This case report describes a patient with long-term suppression of lymphangitic lung metastasis of breast cancer using biweekly TXT without severe side effects or worsening quality of life.

Abstract
Docetaxel has demonstrated activity in a broad range of solid tumors. Phase I trials have shown 100 mg/m(2) every 21 d to be the recommended dose. This phase I trial was designed to define the dose-limiting toxicities (DLTs) and maximum tolerated dose (MTD) of docetaxel with granulocyte colony-stimulating factor (G-CSF) support in patients with advanced solid tumors. Eligible patients had advanced malignancies and up to two prior chemotherapy regimens, ECOG PS = 0 1, adequate organ function, and gave written, informed consent. Docetaxel was escalated in cohorts of patients starting at 100 mg/m(2) on a 21-d schedule. Prophylactic G-CSF was administered on d 3 10. The DLT was defined as grade IV neutropenia >4 d, febrile neutropenia, grade IV thrombocytopenia, any grade III nonhematologic toxicity, or the inability to receive cycle 2 because of ongoing toxicity. Twenty-three patients were enrolled at doses up to 145 mg/m(2). The median age was 59 yr and the median number of prior chemotherapy regimens was 1. No DLT was observed at 100 mg/m(2), and 2 of 11 patients at 120 mg/m(2) experienced DLT (neutropenic fever and stomatitis). At 145 mg/m(2), one of eight patients had DLT (fatigue). Two of eight patients at 145 mg/m(2) had brief grade IV neutropenia (without fever), and none had grade III-IV thrombocytopenia or anemia. The docetaxel dose can be safely escalated to 145 mg/m(2) every 21 d with GCSF support, a 45% increase above the standard recommended phase II dose. Further studies will clarify the role of dose-intensified docetaxel.

Abstract
AIMS To assess efficacy and optimum combination dosage of intravenous docetaxel (T), epirubicin (E) and vinorelbine (N) administered every 2 weeks and without colony stimulating factor (CSF) support in patients with metastatic breast cancer (MBC). PATIENTS AND METHOD Patients (n = 5 1) with MBC were consecutively assigned to four different dose levels (DL) to receive (in mg/m2): Level I = T35 + E30 + N25; Level II = T30 + E30 + N25; Level III = T30 + E25 + N25; and Level IV = T25 + E25 + N25. Consecutive cycles were delayed if absolute neutrophil and/or platelet counts fell below 1.5 x 10(9) and 100 x 10(9) l(-1), respectively. Treatment at a given dose level was suspended if 33% or more of patients included in a given cohort had unacceptable toxicity. RESULTS The patients evaluable for toxicity (n = 48) received 448 cycles (median 9; range 1-23). There was neutropenia G 3-4 in 30 patients (63%) with fever in 3 (6%). The G 2-3 non-hematological toxicities were alopecia in 39 patients (81%), mucositis in 11 (23%), and nausea/vomiting in 8 (17%). There were no toxic deaths. Treatment delay or dose reduction after first cycle occurred in > or = 30% of patients treated in all DLs, except the fourth. Objective response was achieved in 29 of the 47 evaluable patients (58%; 95% CI: 50-66). The median duration of response, time-to-progression and overall survival were 13, 11 (range 8-14) and 20 (range 16-24) months, respectively. CONCLUSION The combination of docetaxel, epirubicin and vinorelbine without CSF support ought not to exceed 25 mg/m2 every 2 weeks. The efficacy is no greater than other existing regimens for first-line treatment of MBC.

Abstract
The purpose of the study was to determine the efficacy and safety of docetaxel plus continuous infusion of 5-fluorouracil (5-FU) in patients with metastatic breast cancer previously treated with anthracyclines. A total of 41 patients with histologically proven metastatic breast cancer and performance status 0-2, who had received at least one anthracycline-containing regimen, received docetaxel 85 mg m(-2) followed by continuous infusion of 5-FU 750 mg m(-2) day(-1) for 5 days every 3 weeks for up to eight cycles. All patients received corticosteroid premedication, but there was no prophylactic colony-stimulating factor support. The most frequent metastatic sites were the liver (61%), bone (29%), and lung (29%). All 41 patients were assessable for toxicity and 30 were eligible and assessable for efficacy. The objective response rate was 70.0% (95% CI: 53.6-86.4%) for the per protocol group and 53.7% (95% CI: 38.4-68.9%) for the intent-to-treat (ITT) population. For the ITT population, median duration of response was 8.4 months (95% CI: 6.7-12.2 months), median time to progression was 6.7 months (95% CI 5.5-8.6 months), and median survival was 17 months (95% CI: 12.3-not recorded months). Grade 3/4 neutropenia occurred in 54% of patients, with febrile neutropenia in 24% of patients and 5% of cycles, but infections were rare. Stomatitis was frequent, grade 3 in 24% of patients and grade 4 in one patient (2%), but manageable. Diarrhoea was rare, grade 3 in 7% of patients and 1% of cycles. Other grade 3/4 nonhaematological toxicities were infrequent. In conclusion, this docetaxel/5-FU regimen is highly active and well tolerated in patients with anthracycline-pretreated metastatic breast cancer. The efficacy is particularly promising, as one-third of patients were either second-line and/or anthracycline-resistant/refractory.

Abstract
PURPOSE This randomized, multicenter, phase III study compared doxorubicin and docetaxel (AT) with doxorubicin and cyclophosphamide (AC) as first-line chemotherapy (CT) in metastatic breast cancer (MBC). PATIENTS AND METHODS Patients (n = 429) were randomly assigned to receive doxorubicin 50 mg/m(2) plus docetaxel 75 mg/m(2) (n = 214) or doxorubicin 60 mg/m(2) plus cyclophosphamide 600 mg/m(2) (n = 215) on day 1, every 3 weeks for up to eight cycles. RESULTS Time to progression (TTP; primary end point) and time to treatment failure (TTF) were significantly longer with AT than AC (median TTP, 37.3 v 31.9 weeks; log-rank P =.014; median TTF, 25.6 v 23.7 weeks; log-rank P =.048). The overall response rate (ORR) was significantly greater for patients taking AT (59%, with 10% complete response [CR], 49% partial response [PR]) than for those taking AC (47%, with 7% CR, 39% PR) (P =.009). The ORR was also higher with AT in patients with visceral involvement (58% v 41%; liver, 62% v 42%; lung, 58% v 35%), three or more organs involved (59% v 40%), or prior adjuvant CT (53% v 41%). Overall survival (OS) was comparable in both arms. Grade 3/4 neutropenia was frequent in both groups, although febrile neutropenia and infections were more frequent for patients taking AT (respectively, 33% v 10%, P <.001; 8% v 2%, P =.01). Severe nonhematologic toxicity was infrequent in both groups, including grade 3/4 cardiac events (AT, 3%; AC, 4%). CONCLUSION AT significantly improves TTP and ORR compared with AC in patients with MBC, but there is no difference in OS. AT represents a valid option for the treatment of MBC.

Abstract
Docetaxel has consistently demonstrated its high activity as an antineoplastic agent in the treatment of metastatic breast cancer. However, 90% of patients receiving the recommended dose of 100 mg/m2 every 3 weeks will develop grade 3 or 4 neutropenia. Recent data suggest that the safety profile of a weekly docetaxel regimen compared favorably with the standard 3-week schedule. Thus, we initiated a phase II study to assess the efficacy and toxicity of weekly docetaxel in pretreated patients with metastatic breast cancer. Twenty patients with advanced, anthra-cycline-refractory breast cancer were included in this phase II trial. Docetaxel was administered at a starting dose of 40 mg/m2, repeated once a week for 3 consecutive weeks followed by a 1-week rest period (1 cycle). Patients were evaluated for tumor response every 8 weeks (after every other cycle). Therapy was continued for a maximum of six courses in patients showing tumor response or stable disease. Twenty patients received a total of 204 weekly infusions of docetaxel. The mean number of treatments was 10.2 (range 1-18). Eighteen patients were assessable for response. Five patients achieved a partial response and six patients showed either stable disease or a minor response. Seven patients had disease progression. The median survival was 7.8 months. Grade 3/4 leukopenia occurred in two patients. No other grade 3 or 4 hematologic toxicities were observed. The following grade 3/4 non-hematologic toxicities were seen: nausea/vomiting (one patient), infection (one patient), mucositis (two patients) and diarrhea (one patient). Three patients withdrew from the study due to dose-limiting toxicities (one due to severe neutropenia and two due to mucositis). We conclude that administration of docetaxel at a dose of 40 mg/m2 was effective and well tolerated even in heavily pretreated patients with metastatic breast cancer. This regimen is associated with only mild myelosuppression.

Abstract
This phase I was study conducted to establish the maximum tolerated dose, dose-limiting toxicity, and recommended dose of docetaxel in combination with cyclophosphamide as first-line chemotherapy for metastatic breast cancer. Twenty-six patients were treated with cyclophosphamide (600 mg m(-2), intravenous bolus) followed by docetaxel (60, 75 or 85 mg m(-2), 1-h intravenous infusion) every 3 weeks. The maximum tolerated dose was docetaxel 85 mg m(-2) with cyclophosphamide 600 mg m(-2), the dose-limiting toxicity being febrile neutropenia. Grade 4 neutropenia was experienced by all patients, but was generally brief. Otherwise, the combination was well tolerated with few acute and no chronic non-haematological toxicities of grade 3/4. Activity was observed at all dose levels and disease sites, and the overall response rate was 42% (95% confidence interval 22-61%). The pharmacokinetics of docetaxel were not modified by cyclophosphamide coadministration. These findings establish a recommended dose of docetaxel 75 mg m(-2) in combination with cyclophosphamide 600 mg m(-2) every three weeks for phase II evaluation.

Abstract
PURPOSE Vinorelbine and docetaxel are two active agents in the treatment of metastatic breast cancer. When given together, these drugs exhibit synergistic antitumor activity without significant pharmacokinetic interaction. The dose-limiting toxicities of this combination are neutropenic fever and mucositis. Adding granulocyte colony-stimulating factor (G-CSF) might lessen the toxicity and increase the maximum tolerated dose (MTD) of this combination. The aim of this study was to determine the MTD of vinorelbine and docetaxel given in combination with G-CSF. PATIENTS AND METHODS Between August 1997 and December 1998, 14 patients with metastatic breast cancer were enrolled in this study. All patients had received doxorubicin-based therapy, and 46% had received paclitaxel in the adjuvant or neoadjuvant setting. Patients were treated with vinorelbine at a starting dose of 20 mg/m2 intravenously over 10 min on days 1 and 5 and docetaxel at a starting dose of 85 mg/m2 intravenously over 1 hr on day 1, following the vinorelbine. Treatments were repeated every 21 days. Prophylactic G-CSF 5 mcg/kg was given subcutaneously on days 3-10. Toxicity was graded according to the National Cancer Institute's grading system. RESULTS A total of 65 cycles was administered at dose levels 0, -1, -2, and -3. The median absolute granulocyte count nadir for all courses was 200 mm(-3) (range, 0.1-7700 mm(-3)), and the median time to this nadir was 9 days (range, 7-30). The median platelet nadir was 163 (range, 27-401 k), and the median time to this nadir was 8 days (range, 7-30). The most common grade 3 nonhematologic toxicities for all courses were fatigue and myalgia, which occurred in 32 and 10 cycles, respectively. Neutropenic fever was encountered in 11 cycles. Three patients developed colitis-like pictures, two of whom died as a result. Consequently, the protocol was closed to accrual before a MTD was reached. CONCLUSION The combination of vinorelbine, docetaxel, and G-CSF in our hands has proven to be a toxic regimen, even when relatively low doses of vinorelbine and docetaxel are given. Meticulous observation of patients receiving this combination is warranted since the combination resulted in two deaths in this study.

Abstract
Early drug development at EORTC has always been subject to structural changes to adapt to the rapid changes that occur in oncological drug development. The expertise of early drug developers has always been cross-fertilised with disease-/tumour-oriented groups and also backwards to the laboratory research groups. This results in the establishment of a solid and dedicated network of medical oncologists with focused expertise in cancer drug development. The EORTC Data Center is fully equipped with all expertise to support clinical research activities and includes regulatory, safety, and quality assurance desks. The EORTC New Drug development Programme (NDDP) provides methodological expertise to early clinical trials and coordinates phase I and phase II studies addressing various approaches. Through NDDP, the early clinical groups and the disease-/tumour-oriented groups have created specific networks to address early drug development in specific tumour types. This results in very efficient networks which have the resources and the patients to address and conduct challenging clinical trials in a standardised fashion ensuring the highest standards in cancer treatment.

Abstract
BACKGROUND This study was conducted to investigate the efficacy and toxicity of weekly docetaxel administration in patients with metastatic breast cancer. PATIENTS AND METHODS Thirty-seven women were treated with 1 h infusions of docetaxel at 40 mg/m2/week after pre-medication with 8 mg dexamethazone. Each cycle consisted of three consecutive weekly treatments followed by a 1 week rest. All patients were assessed for toxicity; five patients were not assessable for clinical response, time to progression (TTP) and overall survival (OS) because of early treatment failure, but they were included in intention-to-treat analysis. RESULTS Patients received a median of four cycles (range, 1-9), with a median dose intensity of 28 mg/m2/week (range 22-30) and a median relative dose intensity of 0.95 (range 0.73-1.0). No patients showed complete response, whereas 14 had partial response, which accounted for 38% of objective response rate [95% confidence interval (CI) 22% to 53%]. In addition, three patients (8%, 95% CI 0% to 17%) had stable disease over 6 months. Clinical responses were achieved at a median of three cycles (range 1-4 cycles). The median TTP and OS were 5 and 12 months, respectively. The weekly docetaxel regimen was generally well tolerated. About half of the patients experienced grade > or = 1 neutropenia; only 19% had grade 3/4 neutropenia, including one case of grade 4. No febrile neutropenia was observed and fluid retention syndrome was uncommon. Non-hematologic toxicity, however, such as asthenia/fatigue, nail damage, tearing or hearing disorders, was seen with successive treatment cycles. CONCLUSIONS Weekly docetaxel at 40 mg/m2/week is an active and feasible regimen for patients with metastatic breast cancer.

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
Although docetaxel (Taxotere; TXT), a taxoid anticancer drug, is clinically and experimentally very effective against breast cancer, its antitumor effect is of very short duration. We addressed whether 5-fluorouracil (5-FU) and its derivatives can act synergistically with TXT against mammary tumors, with placing particular stress on their use by oral route. Mouse mammary tumor cell line, MM2, was propagated in culture and as ascites in mice. Carmofur (HCFU) and doxifluridine (5'-DFUR) were used as 5-FU derivatives. In vitro, the cytotoxic effects of antitumor drugs on MM2 cells were examined by MTS assay. In vivo, mice inoculated i.p. with MM2 cells were treated with i.p. injection of TXT and/or oral administration of 5-FU or its derivatives, and observed for curing tumor. In vitro, the synergistic effects were observed in the combination of TXT and 5-FU or HCFU, but not in that of TXT and 5'-DFUR. In vivo, all of these combinations cured tumors far more effectively than TXT alone. The discrepant result of the combination of TXT and 5'-DFUR between in vitro and in vivo was ascribed to up-regulation of pyrimidine phosphorylase in tumor cells in vivo by TXT. Thus, 5-FU, its masked compounds like HCFU and its prodrugs like 5'-DFUR can act synergistically with TXT in the therapy of cancer even when administered by the oral route.

Abstract
BACKGROUND Pancreatic adenocarcinoma (PAC) is generally refractory to most chemotherapeutic agents, including docetaxel (Taxotere; TXT). Specific mechanisms for TXT-related drug resistance in PAC have not been defined. The hypothesis of this study was that PAC resistance to TXT is primarily related to P-glycoprotein (P-gp), the expression product of multiple drug resistance (MDR)-1, as opposed to lung resistance protein (LRP) or multidrug resistance protein (MRP). MATERIALS AND METHODS The sensitivity of the PAC cell line SUIT-2 and its sublines to TXT, doxorubicin (DOX) and 5-fluorouracil (5-FU) was evaluated with a 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay. MDR1 (P-gp), MRP, LRP, and beta-tubulin isotype gene expressions were detected at the messenger RNA level by reverse transcription-polymerase chain reaction (RT-PCR). Verapamil and indomethacin (IMC) were used to test the functionality of P-gp and MRP, respectively. RESULTS The SUIT-2 subline S-020 and the TXT-selected SUIT-2 cell line S2/TXT were significantly resistant to TXT. Both showed cross-resistance to DOX but no resistance to 5-FU. RT-PCR demonstrated strong expression of P-gp in S-020 and S2/TXT and weaker or no expression in other cells lines. MRP and LRP expression was found in most of these cell lines but had no relationship to the TXT resistance. TXT resistance in S2-020 and S2/TXT could be reversed by verapamil but not by IMC. Levels of beta-tubulin isotype II and III were increased in S2/TXT compared with S-020 and SUIT-2. CONCLUSIONS Intrinsic and acquired TXT resistance is primarily mediated by P-gp, but not by MRP or LRP, and is markedly reversed by the P-gp modulator verapamil. Hence future related studies should focus on the use of agents that block the transporter action of P-gp.

Abstract
BACKGROUND AND PURPOSE Anthracycline-containing regimens are widely used in advanced breast cancer. However, there is a need for new, non-anthracycline regimens that are active in patients for whom anthracyclines are contraindicated. The aim of this study was to determine the maximum tolerated dose (MTD), the dose-limiting toxicities (DLTs) and recommended doses of docetaxel and vinorelbine as first-line chemotherapy in patients with metastatic breast cancer. The pharmacokinetics of both drugs was also evaluated. PATIENTS AND METHODS Thirty-four women with first-line metastatic breast cancer were treated with docetaxel, 60-100 mg/m2 (day 1), and vinorelbine, 20-22.5 mg/m2 (days 1 and 5), repeated every three weeks and administered on an outpatient basis. RESULTS Two MTDs were determined: MTD1 was defined at the dose level using docetaxel 75 mg/m2, and vinorelbine 22.5 mg/m2 DLT being a grade 3 stomatitis that was more related to the dose of vinorelbine than that of docetaxel. Therefore, the study continued with a fixed dose of vinorelbine, 20 mg/m2, and docetaxel 85-100 mg/m2. MTD2 was defined at the dose level combining docetaxel, 100 mg/m2, and vinorelbine, 20 mg/m2; DLTs were grade 3 stomatitis and severe asthenia. Fluid retention was observed in 41% of patients but was never severe or a reason for patient discontinuation. In comparison with historical experience, Daflon 500 did not seem to increase the efficacy of the three-day corticosteroid premedication by further reducing the incidence or severity of fluid retention. No significant neurotoxicity was observed and no patient discontinued the study due to this site effect. Activity was observed at all dose levels and at all metastatic sites, with an overall response rate of 71% (95% CI: 52.0%-85.8%). The median time to progression was 31.4 weeks (95% CI: 12-48 weeks) and median survival was 15.6 months (95% CI: 2.6-26.6 months). The pharmacokinetics of docetaxel and vinorelbine were not modified between day 1 and day 3 when the two drugs were combined with the day 1 administration schedule used in this study. CONCLUSION The recommended doses for phase II studies are docetaxel, 75 mg/m2 (day 1), plus vinorelbine, 20 mg/m2 (days 1 and 5), repeated every three weeks. At these doses, the combination was found to be active and well tolerated.

Abstract
STUDY AIM To report results of liver resections for breast cancer liver metastasis (BCLM) and to evaluate the rate of survival and the prognostic factors. PATIENTS AND METHOD Between 1988 and 1999, 69 patients were operated on for BCLM and 65 who had liver resection were analyzed. The selection criteria for surgery were: normal performance status and liver function test; radiological objective response to chemotherapy (and/or hormonotherapy); in cases of non-isolated BCLM, complete response of associated metastatic site (usually bone) and no brain metastases. The mean age of the 65 patients was 47 (30-70) years. BCLM was diagnosed an average of 60 (0-205) months after the initial cancer. The BCLM was more frequently solitary (n = 44). The mean diameter was 3.8 (0-12) cm. The mean number of cycles of chemotherapy before surgery was 7.5 (3-24). Liver resections included major hepatectomy (n = 31): right n = 19, extended left n = 4, left n = 8, minor hepatectomy (n = 25) and limited resection (n = 9). RESULTS There was no postoperative mortality. The 18% morbidity rate included a majority of pleural effusions with two reoperations. The median follow-up was 41 months (6-100 months). The survival rate after surgery was 90% at 1 year, 71% at 3 and 46% at 4 years. Thirteen patients are alive at 4 years. The 36-month survival rate differed according to the time to onset of BCLM: 55% before versus 86% after 48 months (p = 0.01). The other studied factors were not statistically associated with survival. The recurrence rate in the remaining liver at 36 months differed according to the lymph node status of the initial breast cancer: 40% for N0-N1 versus 81% for N1b-N2 (p = 0.01) and according to the type of liver resection: 45% for minor liver resection versus 73% for major (p = 0.02). CONCLUSION Adjuvant liver surgery should be included in multicenter treatment protocols for medically-controlled breast cancer liver metastasis.

Abstract
PURPOSE This phase III trial compared the efficacy and safety of doxorubicin and paclitaxel (AT) to 5-fluorouracil, doxorubicin, and cyclophosphamide (FAC) as first-line therapy for women with metastatic breast cancer. PATIENTS AND METHODS A total of 267 women with metastatic breast cancer were randomized to receive either AT (doxorubicin 50 mg/m(2) followed 24 hours later by paclitaxel 220 mg/m(2)) or FAC (5-fluorouracil 500 mg/m(2), doxorubicin 50 mg/m(2), cyclophosphamide 500 mg/m(2)), each administered every 3 weeks for up to eight cycles. Patients had to have measurable disease and an Eastern Cooperative Oncology Group performance status of 0 to 2. Only one prior non-anthracycline, nontaxane-containing adjuvant chemotherapy regimen was allowed. RESULTS Overall response rates for patients randomized to AT and FAC were 68% and 55%, respectively (P =.032). Median time to progression and overall survival were significantly longer for AT compared with FAC (time to progression 8.3 months v 6.2 months [P =.034]; overall survival 23.3 months v 18.3 months [P =.013]). Therapy was generally well-tolerated (median of eight cycles delivered in each arm). Grade 3 or 4 neutropenia was more common with AT than with FAC (89% v 65%; P <.001); however, the incidence of fever and infection was low. Grade 3 or 4 arthralgia and myalgia, peripheral neuropathy, and diarrhea were more common with AT, whereas nausea and vomiting were more common with FAC. The incidence of cardiotoxicity was low in both arms. CONCLUSION AT conferred a significant advantage in response rate, time to progression, and overall survival compared with FAC. Treatment was well-tolerated with no unexpected toxicities.

Abstract
PURPOSE To evaluate the efficacy of docetaxel 60 mg/m2 in metastatic breast cancer (MBC) according to the status of anthracycline resistance. PATIENTS AND METHODS Ninety-nine patients with anthracycline-resistant MBC were treated with docetaxel 60 mg/m2 intravenously for a 90-minute period every 3 to 4 weeks. Anthracycline resistance was defined as primary and secondary resistance. Primary resistance was defined as progression during or within 6 months after completion of adjuvant anthracycline, and no MBC response to a first-line regimen that contained anthracycline. Secondary resistance was defined as progression after a documented clinical response to a first-line anthracycline treatment for MBC. Secondary resistance was further divided into three categories: (1) absolute resistance, or progression during treatment with anthracycline after a period of response; (2) relative resistance, or progression within 6 months after anthracycline administration ended; and (3) sensitive regrowth, or progression more than 6 months after the conclusion of anthracycline administration. RESULTS The response rate in the 99 patients was 35.4% (95% confidence interval, 30.1% to 44.8%). The response rates according to the status of anthracycline resistance were as follows: primary resistance (n = 46), 19.6%; secondary resistance (n = 53), 49.1% (absolute resistance [n = 16], 56.3%); relative resistance (n = 17), 47.1%; and sensitive regrowth (n = 20), 45.0%. The median time to treatment failure in patients with primary resistance was 2.9 months, compared with 5.2 months in patients with secondary resistance (P = .0022). CONCLUSION Docetaxel at a dose of 60 mg/m2 seemed to be effective in MBC with secondary resistance to anthracycline. The status of anthracycline resistance is important for the prediction of response to second-line treatment with docetaxel.

Abstract
This phase I study evaluated the maximum tolerated dose, dose-limiting toxicity and recommended dose of docetaxel in combination with 5-fluorouracil (5-FU) in patients with metastatic breast cancer previously treated with anthracycline-based chemotherapy. 32 patients received docetaxel at 60, 75, 85 or 100 mg/m(2) by 1-h intravenous (i.v.) infusion, followed, after a 1-h interval, by 5-FU at 250, 350, 500 or 750 mg/m(2)/day by continuous infusion over 5 days every 3 weeks. Dose-limiting stomatitis defined the maximum tolerated dose at a docetaxel dose of 100 mg/m(2) with 5-FU 750 mg/m(2)/day. None of 5 patients treated at the previous dose level (docetaxel 85 mg/m(2) with 5-FU 750 mg/m(2)/day) had a dose-limiting toxicity in the first cycle, and this was, therefore, considered the recommended dose. The combination was generally well tolerated. Grade 4 neutropenia was common (29 patients; 91%), but no patient experienced febrile neutropenia of duration >3 days requiring i.v. antibiotics. An objective response was achieved by 18 patients overall (56%), and in 4 out of 5 patients treated with the determined recommended dose. No pharmacokinetic interaction between docetaxel and 5-fluorouracil was apparent. The activity of docetaxel 85 mg/m(2) with 5-fluorouracil 750 mg/m(2)/day will be explored more extensively in phase II studies of patients with metastatic breast cancer previously treated with anthracycline-based chemotherapy.

Abstract
The purpose of this study was a retrospective analysis of docetaxel in a cohort of anthracyclines and paclitaxel pretreated patients with metastatic breast cancer. From July 1998 to June 1999, 24 consecutive patients were included for this study. The regimen consisted of docetaxel 75 mg/m2 in combination with a 3-day schedule of dexamethasone every 3 weeks until disease progression or unacceptable toxicity. The median age of patients was 53 (ranged 32-67) years with a median performance status of 2. Twenty of the 24 patients (84%) had measurable disease. The median number of organs involved was 2 (range 1-4). A total of 146 cycles chemotherapy were given with a mean of 6. There was a 25% (six of 24) overall response rate including one complete response, 37.5% stable disease and 37.5% progressive disease. The major toxicity included grade 3-4 leukopenia (41.7%) and eight episodes of infection. No treatment-related death was observed. The responders included patients refractory to or resistant to prior paclitaxel treatment. The median survival and median time to disease progression was 12 and 9 months, respectively. We conclude that docetaxel has a modest activity in breast cancer patients pre-treated with anthracyclines and paclitaxel, indicating a partial cross-resistance between paclitaxel and docetaxel.

Abstract
Paclitaxel and docetaxel are excellent agents with a high antitumor effect for the treatment of previously anthracycline-exposed metastatic breast cancer. There has been no standard treatment for patients who undergo therapy of a taxan-resistant metastatic breast cancer. Paclitaxel has partial non-cross-resistance in vitro with docetaxel in inhibiting microtubule disaggregation. We present the case of a patient with docetaxel-refractory anthracycline-pretreated metastatic breast cancer who achieved remission with paclitaxel.

Abstract
Docetaxel has proven effective in advanced breast cancer. Myelosuppression and cumulative fluid retention syndrome are troublesome, potentially avoidable toxicities. In this consecutive cohort study, docetaxel (100 mg/m2 by 1 hour i.v. infusion, q3 weeks) activity and toxicity was explored in 56 anthracycline-pretreated patients (eligible: 55: median age: 51 years [range: 28-68 years]; median performance status: 0 [range: 0-3]) with metastatic breast cancer, using two different granulocyte colony-stimulating factor and steroid pre- and postmedication schedules. Twenty-nine patients (group A) received a 5-day oral prednisone premedication, and 26 (group B) received 4-day low-dose i.m. dexamethasone; group B patients also received prophylactic granulocyte colony-stimulating factor. All patients were evaluable for toxicity and 53 for response. Prophylactic granulocyte colony-stimulating factor significantly lowered the incidence of grade III-IV neutropenia and neutropenic fever (p = 0.0001 and 0.01, respectively). The incidence of moderate-severe fluid retention syndrome was lower in patients receiving i.m. dexamethasone (p = 0.08). Overall response rate was 53% (4 complete responses/24 partial responses, 95% confidence interval 39.4-66.2%); 32% have stable disease and 15% progressive disease. In 21 anthracycline-refractory/resistant patients, as well as in 10 paclitaxel-pretreated patients, the overall response rate was 50%. Docetaxel is highly active in anthracycline- and paclitaxel-pretreated metastatic breast cancer, with manageable toxicity. Optimal use of both granulocyte colony-stimulating factor support and steroid premedication deserves further investigation.

Abstract
The aims of this study were to evaluate the efficacy and safety of docetaxel (Taxotere) in patients with progressive locally advanced or metastatic breast cancer, previously treated with at least one chemotherapy regimen, and the effect of the number of previous chemotherapy lines on response rate, progression-free survival and overall survival. Two-hundred and fifty-three patients from 10 hospitals in The Netherlands received docetaxel as part of a compassionate use program. The majority had received prior anthracycline-containing chemotherapy (84.2%). The recommended starting dose was 100 mg/m2 i.v. every 3 weeks. All patients received corticosteroid premedication. Two-hundred and thirty patients were evaluable for response. The overall response rates (ORR) to docetaxel when used as second-, third- or fourth-line treatment were, respectively, 40.2, 26.0 and 34.6% (p value 0.30). The median progression-free survival for this population was 4.9 months and the median overall survival of the whole group was 8.5 months, and both were not related to the number of previous chemotherapy regimens (p value, respectively, 0.71 and 0.16). The toxicity of docetaxel was manageable and neutropenia was the most frequently noted toxicity. This study confirms that docetaxel is an active cytotoxic agent in pretreated patients with progressive locally advanced or metastatic breast cancer and is still active when used as third- or fourth-line treatment.

Abstract
Nineteen breast cancer patients pretreated with one or two anthracycline-containing regimens for visceral metastases received i.v. docetaxel 100 mg/m2 on day 1, q 21d. Docetaxel was administered as second-line therapy in 11 patients, whereas eight patients received docetaxel in a third-line setting. In the second-line setting, complete response (CR) was achieved in two (18%), partial response (PR) in four (36%) and stable disease (SD) in three (27%) patients resulting in a response rate (RR) of 54%. In the third-line setting three (38%) patients experienced PR (RR 38%) and two (25%) SD. In the second-line setting, median time to progression was 6.5+/-3.9 months (range 2.1-15.8) versus 4.7+/-5.5 months (range 0.6-15.9) in the third-line setting. Median overall survival was 9.6+/-8.0 months (range 2.7-25.8) versus 11.2-6.1 months (range 4.8-18.7). Overall, no patient experienced treatment-limiting toxicities. We conclude that docetaxel induced responses in 48% of anthracycline-resistant patients enrolled into the present study. The safety profile of docetaxel was manageable and tolerable. Docetaxel represented efficacious treatment in patients with metastatic breast cancer progressing despite previous anthracycline-containing chemotherapy.

Abstract
AIMS Breast cancer liver metastases (BCLM) usually indicate the presence of disseminated cancer with a very poor prognosis. However, systemic treatments now allow control of tumour progression in certain cases. We evaluated, in a group of highly selected patients with stabilization or complete response to systemic therapy, a particular management protocol for medically controlled BCLM: <<adjuvant>> liver surgery. METHODS Fifty-two patients underwent surgery between May 1988 and September 1997. Results of this strategy are reported, together with analysis of prognostic factors for survival and recurrence in the remaining liver (RRL). RESULTS The mean number of cycles of chemotherapy, before surgery, was seven (3-24). Resection was considered to be curative in 86% of cases. The median follow-up was 23 months (1-72 months). The survival after surgery, was 86% at 12 months, 79% at 24 months and 49% at 36 months. The 36-month survival rate differed according to the time to onset of BCLM: 45% before versus 82% after 48 months (P=0.023). The RRL rate at 36 months differed according to the lymph node status of the initial breast cancer: 41% for N0-N1 versus 83% for N1b-N2 (P=0.021). CONCLUSIONS Adjuvant liver surgery allowed discontinuation of chemotherapy in 46% of cases and, in this highly selected patient group, allowed good quality prolonged survival. It could be included in multicentre treatment protocols for controlled BCLM, one arm with prolonged chemotherapy, one with adjuvant liver surgery.

Abstract
PURPOSE To evaluate the safety and efficacy of weekly docetaxel in women with metastatic breast cancer. PATIENTS AND METHODS Twenty-nine women were enrolled onto a study of weekly docetaxel given at 40 mg/m(2)/wk. Each cycle consisted of 6 weeks of therapy followed by a 2-week treatment break, repeated until disease progression or removal from study for toxicity or patient preference. Fifty-two percent of patients had been previously treated with adjuvant chemotherapy; 21% had received prior chemotherapy for metastatic breast cancer, and 31% had previously received anthracyclines. All patients were assessable for toxicity; two patients were not assessable for response but are included in an intent-to-treat analysis. RESULTS Patients received a median of 18 infusions, with a median cumulative docetaxel dose of 720 mg/m(2). There were no complete responses. Twelve patients had partial responses (overall response rate, 41%; 95% confidence interval, 24% to 61%), all occurring within the first two cycles. Similar response rates were observed among subgroups of patients previously treated either with any prior chemotherapy or with anthracyclines. An additional 17% of patients had stable disease for at least 6 months. The regimen was generally well tolerated. There was no grade 4 toxicity. Only 28% of patients had any grade 3 toxicity, most commonly neutropenia and fatigue. Acute toxicity, including myelosuppression, was mild. Fatigue, fluid retention, and eye tearing/conjunctivitis became more common with repetitive dosing, although these side effects rarely exceeded grade 2. Dose reductions were made for eight of 29 patients, most often because of fatigue (n = 5). CONCLUSION Weekly docetaxel is active in treating patients with metastatic breast cancer, with a side effect profile that differs from every-3-weeks therapy.

Abstract
Among the novel chemotherapeutic drugs introduced in the last decade, taxanes have emerged as the most powerful compounds and results available to date suggest that they will be remembered in the future as the breast cancer chemotherapy of the 1990s. The two taxanes (paclitaxel, Taxol, Bristol-Myers Squibb and docetaxel, Taxotere, Rhône-Poulenc Rorer) share some characteristics, but are also significantly different both in preclinical profile and, most importantly, in clinical characteristics. The main clinical differences are related to their different efficacy-toxicity ratio in relation to dose and schedule; the differing integrability of paclitaxel and docetaxel in anthracycline-taxane containing regimens, secondary to major differences in pharmacokinetic interactions between each taxane and the anthracyclines, and; the potential differences in level of synergism between each taxane and herceptin (HeR2Neu antibody/trastuzumab, Genentech/Roche). In clinical practice, the taxanes are now standard therapy in metastatic breast cancer after prior chemotherapy, in particular anthracyclines, has failed. Their role in combination with anthracyclines in first-line therapy of advanced breast cancer is emerging and sheds new light on the potential role of taxanes in the adjuvant setting. However, the impact of taxanes on the natural history of breast cancer is yet to be defined, despite the trend of results suggesting that these agents have the potential for significant improvements in advanced and, most importantly, adjuvant therapy of breast cancer. The results of all completed or ongoing Phase III trials in first-line metastatic and the adjuvant setting will help determine if taxanes will further improve the outcome of breast cancer or not.
