Abstract
Simple Summary Chemotherapy is the gold standard treatment option for metastatic cancers. However, the efficacy of chemotherapy is limited due to the development of resistance. The aberrantly expressed Wnt/β-catenin signaling pathway acts as one of the major cancer drivers that also causes the development of resistance. Therefore, in this study, we explored the combinatorial approach of downregulating the Wnt/β-catenin pathway along with using a chemotherapeutic agent as a strategy to overcome drug resistance and improve cancer therapy. We evaluated the combinatorial efficacy of Niclosamide (an antihelminthic repurposed as a Wnt signaling inhibitor) and Doxorubicin (first-line treatment for multiple cancers in the clinic) against breast cancer. The combination showed synergistically enhanced death of all three clinical subtypes of breast cancer cells in both the sequential and concurrent treatment regimens and holds the potential to be developed as an efficient therapeutic option for breast cancer irrespective of its clinical subtype. Abstract Drug resistance is one of the major hurdles in the success of cancer chemotherapy. Notably, aberrantly expressed Wnt/β-catenin signaling plays a major role in the initiation and maintenance of oncogenesis along with development of chemoresistance. Therefore, the combinatorial approach of targeting Wnt/β-catenin pathway along with using a chemotherapeutic agent seems to be a promising strategy to improve cancer therapy. In the present study, we evaluated the combination of niclosamide (Nic), an FDA-approved antihelminthic drug repurposed as a Wnt signaling inhibitor, and doxorubicin (Dox), a conventional anticancer agent, in all clinical subtypes of breast cancer viz. triple negative breast cancer, HER2 positive breast cancer, and hormone receptor positive breast cancer. The results demonstrated that the combination induced apoptosis and caused synergistically enhanced death of all breast cancer cell types at multiple combinatorial concentrations using both the sequential and concurrent treatment regimens. Mechanistically, downregulation of Wnt/β-catenin signaling and cell cycle arrest at G0/G1 phase by Nic and increase in reactive oxygen species by both Nic and Dox along with the inherent cytotoxicity of Dox mediated the synergism between the two drugs in both the treatment regimens. Overall, the combination of Nic and Dox holds promise to be developed as an efficient therapeutic option for breast cancer irrespective of its clinical subtype.

Abstract
Porphyrin iron molecules (hemin) were successfully grafted on the channeled mesoporous silica of SBA-15 (FeIX-SBA-15), in which attached hemin molecules acted as the enzyme mimic for catalyzing oxidation reactions. In the presence of H2O2, the prepared FeIX-SBA-15 composite effectively degraded industrial dye Orange II and catalyzed tetramethylbenzidine hydrochloride (TMB) both in the solution and on the membrane, from which the colorimetric H2O2 detection was achieved. Moreover, the hemin-grafted composites showed high loading content of anticancer drug of doxorubicin hydrochloride (DOX) displaying the sustained releasing behavior as monitored by real-time cell analysis, which resulted in improved inhibitory effect on cancer cells growth compared with that DOX/SBA-15. The hemin-modified mesoporous silica nanocomposite provides an integrated nanoplatform with promising biomedical applications.

Abstract
PURPOSE OF REVIEW Cancer and heart disease are the leading causes of mortality in the USA. Advances in cancer therapies, namely, the development and use of chemotherapeutic agents alone or in combination, are becoming increasingly prevalent. RECENT FINDINGS Many chemotherapeutic agents have been associated with adverse cardiovascular manifestations. The mechanisms of these sequelae remain incompletely understood. In particular, microtubule inhibitor (MTI) agents have been related to the development of heart failure, myocardial ischemia, and conduction abnormalities. At present, there are no guidelines for patients undergoing MTI therapy as it pertains to both preventative and mitigatory strategies for cardiovascular complications. We conducted a literature review focusing on content related to the use of MTIs and their effect on the cardiovascular system. MTIs have been associated with various forms of cardiotoxicity, and fatal cardiotoxicities are rare. The most well-described cardiotoxicities are brady- and tachyarrhythmias. The co-administration of anthracycline-based agents with MTIs can increase the risk of cardiotoxicity.

Abstract
Core-shell nanostructures are promising platforms for combination drug delivery. However, their complicated synthesis process, poor stability, surface engineering, and low biocompatibility are major hurdles. Herein, a carboxymethyl chitosan-coated poly(lactide-co-glycolide) (cmcPLGA) core-shell nanostructure is prepared via a simple one-step nanoprecipitation self-assembly process. Engineered core-shell nanostructures are tested for combination delivery of loaded docetaxel and doxorubicin in a cancer-mimicked environment. The drugs are compartmentalized in a shell (doxorubicin, Dox) and a core (docetaxel, Dtxl) with loading contents of ∼1.2 and ∼2.06%, respectively. Carboxymethyl chitosan with both amine and carboxyl groups act as a polyampholyte in diminishing ζ-potential of nanoparticles from fairly negative (-13 mV) to near neutral (-2 mV) while moving from a physiological pH (7.4) to an acidic tumor pH (6) that can help the nanoparticles to accumulate and release the drug on-site. The dual-drug formulation was found to carry a clinically comparable 1.7:1 weight ratio of Dtxl/Dox, nanoengineered for the sequential release of Dox followed by Dtxl. Single and engineered combinatorial nanoformulations show better growth inhibition toward three different cancer cells compared to free drug treatment. Importantly, Dox-Dtxl cmcPLGA nanoparticles scored synergism with combination index values between 0.2 and 0.3 in BT549 (breast ductal carcinoma), PC3 (prostate cancer), and A549 (lung adenocarcinoma) cell lines, demonstrating significant cell growth inhibition at lower drug concentrations as compared to single-drug control groups. The observed promising performance of dual-drug formulation is due to the G2/M phase arrest and apoptosis.

Abstract
Doxorubicin (Dox) is an anthracycline antibiotic widely used in clinics as an anticancer agent. However, the use of Dox is limited by its cardiotoxicity. We have previously shown that a Danshensu (DSS) derivative, ADTM, displayed strong cardioprotective effects. With improved chemical stability and activity, a novel DSS derivative, D006, based on the structure of ADTM, was synthesized. In the present study, the protective effects of D006, indexed by attenuation of the cardiotoxicity induced by Dox as well as chemosensitizing effects that increase the antitumor activity of Dox, were investigated. Our results showed that D006 was more potent than either parental compound, or their use in combination, in ameliorating Dox-induced toxicity in H9c2 cells. In our zebrafish model, D006, but not DSS, alone significantly preserved the ventricular function of zebrafish after Dox treatment. Moreover, D006 upregulated mitochondrial biogenesis and increased mtDNA copy number after Dox treatment of H9c2 cells. D006 promoted the expression of HO-1 protein in a time-dependent manner while the HO-1 inhibitor, Znpp, reversed the protective effects of D006. In human breast tumor MCF-7 cells, D006 enhanced Dox-induced cytotoxicity by increasing apoptosis. In conclusion, our results indicate that a new DSS derivative exhibits promising protective effects against Dox-induced cardiotoxicity both in vivo and in vitro, an effect at least partially mediated by induction of HO-1 expression and the activation of mitochondrial biogenesis. Meanwhile, D006 also potentiated the anti-cancer effects of Dox in breast tumor cells.

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
Previously synthesized amphiphilic diblock copolymers with pendant dendron moieties have been investigated for their potential use as drug carriers to improve the delivery of an anticancer drug to human breast cancer cells. Diblock copolymer (P71 D3 )-based micelles effectively encapsulate the doxorubicin (DOX) with a high drug-loading capacity (≈95%, 104 DOX molecules per micelle), which is approximately double the amount of drug loaded into the diblock copolymer (P296 D1 ) vesicles. DOX released from the resultant P71 D3 /DOX micelles is approximately 1.3-fold more abundant, at a tumoral acidic pH of 5.5 compared with a pH of 7.4. The P71 D3 /DOX micelles also enhance drug potency in breast cancer MDA-MB-231 cells due to their higher intracellular uptake, by approximately twofold, compared with the vesicular nanocarrier, and free DOX. Micellar nanocarriers are taken up by lysosomes via energy-dependent processes, followed by the release of DOX into the cytoplasm and subsequent translocation into the nucleus, where it exert its cytotoxic effect.

Abstract
PURPOSE Pegylated granulocyte-colony-stimulating factor (G-CSF) is frequently used to prevent febrile neutropenia (FN) in patients undergoing chemotherapy with a high risk of myelosuppression. This phase II/III study was conducted to determine the adequate dose of pegteograstim, a new formulation of pegylated G-CSF, and to evaluate the efficacy and safety of pegteograstim compared to pegfilgrastim. METHODS In the phase II part, 60 breast cancer patients who were undergoing DA (docetaxel and doxorubicin) or TAC (docetaxel, doxorubicin, and cyclophosphamide) chemotherapy were randomly selected to receive a single subcutaneous injection of 3.6 or 6.0 mg pegteograstim on day 2 of each chemotherapy cycle. The phase III part was seamlessly started to compare the dose of pegteograstim at selected in phase II with 6.0 mg pegfilgrastim in 117 breast cancer patients. The primary endpoint of both the phase II and III parts was the duration of grade 4 neutropenia in the chemotherapy cycle 1. RESULTS The mean duration of grade 4 neutropenia for the 3.6 mg pegteograstim (n = 33) was similar to that for the 6.0 mg pegteograstim (n = 26) (1.97 ± 1.79 days vs. 1.54 ± 0.95 days, p = 0.33). The 6.0 mg pegteograstim was selected to be compared with the 6.0 mg pegfilgrastim in the phase III part. In the phase III part, the primary analysis revealed that the efficacy of pegteograstim (n = 56) was non-inferior to that of pegfilgrastim (n = 59) [duration of grade 4 neutropenia, 1.64 ± 1.18 days vs. 1.80 ± 1.05 days; difference, -0.15 ± 1.11 (p = 0.36, 97.5 % confidence intervals = 0.57 and 0.26)]. The time to the absolute neutrophil count (ANC) recovery of pegteograstim (≥2000/μL) was significantly shorter than that of pegfilgrastim (8.85 ± 1.45 days vs. 9.83 ± 1.20 days, p < 0.0001). Other secondary endpoints showed no significant difference between the two groups. The safety profiles of the two groups did not differ significantly. CONCLUSIONS Pegteograstim was shown to be as effective as pegfilgrastim in the reduction of chemotherapy-induced neutropenia in the breast cancer patients who were undergoing chemotherapy with a high risk of myelosuppression.

Abstract
The importance of the size of targeted, spherical drug carriers has been previously explored and reviewed. Particle shape has emerged as an equally important parameter in determining the in vivo journey and efficiency of drug carrier systems. Researchers have invented techniques to better control the geometry of particles of many different materials, which have allowed for exploration of the role of particle geometry in the phases of drug delivery. The important biological processes include clearance by the immune system, trafficking to the target tissue, margination to the endothelial surface, interaction with the target cell, and controlled release of a payload. The review of current literature herein supports that particle shape can be altered to improve a system's targeting efficiency. Non-spherical particles can harness the potential of targeted drug carriers by enhancing targeted site accumulation while simultaneously decreasing side effects and mitigating some limitations faced by spherical carriers.

Abstract
This trial compared 6 cycles of fluorouracil, epirubicin, and cyclophosphamide (FEC) with a sequential regimen of 3 cycles of FEC followed by 3 cycles of docetaxel (FEC-D) as adjuvant treatment for women with node-positive or/and T3 or T4 breast cancer. Between January 2006 and January 2010, 657 patients with operable breast cancer were randomly assigned to either FEC every 21 days for 6 cycles, or 3 cycles of FEC followed by 3 cycles of docetaxel, both given every 21 days. Radiotherapy was mandatory for all patients who had undergone breast conserving surgery. Radiation to the chest wall, supraclavicular area, was recommended following mastectomy. Hormone-receptor-positive patients received tamoxifen for 5 years after chemotherapy. The primary end point was 5-year disease-free survival (DFS). Median follow-up was 61 months. Five-year DFS rates were 74 % with FEC and 78 % with FEC-D (P = 0.013). Multivariate analysis adjusted for prognostic factors showed a 17 % reduction in the relative risk of relapse with FEC-D. Five-year overall survival rates were 85 % with FEC and 89.4 % with FEC-D, demonstrating a 27 % reduction in the relative risk of death (P = 0.014). The incidence of grade 3-4 neutropenia, the need for hematopoietic growth factor, and incidence of nausea/vomiting were higher with FEC. Docetaxel was associated with more febrile neutropenia, stomatitis, edema, and nail disorders. Though rare overall, there were fewer cardiac events after FEC-D, attributable mainly to the lower anthracycline cumulative dose. Sequential adjuvant chemotherapy with FEC followed by docetaxel significantly improves disease-free and overall survival in node-positive or/and T3 or T4 breast cancer patients. Although the magnitude of the benefit observed with FEC-D, differences in the toxicity profiles of FEC and FEC-D may influence the choice of treatment for patients.

Abstract
The introduction of taxanes in the armamentarium against breast cancer in the 1990s has been one of the landmarks in the treatment of this disease. Docetaxel in particular is considered one of the most active cytotoxic agents in metastatic breast cancer and has also been tested as adjuvant postsurgical therapy in earlier stages. A regimen including docetaxel, doxorubicin and cyclophosphamide (the TAC regimen) was the first combination that demonstrated the efficacy of docetaxel in the adjuvant setting. This combination has been approved by regulatory agencies for adjuvant therapy of node-positive breast cancer and is presently used worldwide. TAC is more toxic than the traditional anthracycline-containing combinations, but many of its side effects can be ameliorated with colony-stimulating growth factor support.

Abstract
AIM Non-pegylated liposomal doxorubicin (NPLD) has demonstrated equivalent antitumour activity to conventional doxorubicin and a significantly lower risk of cardiotoxicity when given as a single agent or in combination with cyclophosphamide. This phase II trial was performed to evaluate the efficacy and the safety of NPLD and docetaxel combination in patients with metastatic breast cancer previously exposed to adjuvant anthracyclines. PATIENTS AND METHODS Thirty-four patients received NPLD 60 mg/m(2) and docetaxel 75 mg/m(2) in a 21-day cycle as first-line therapy of metastatic breast cancer. Treatment was planned for six cycles and was continued until progression or toxicity. RESULTS Objective response rate among response-assessable patients was 79% (95% CI (confidence interval), 64-94%) and 27% (95% CI, 11-43%) presented a complete response. Median progression free survival was 11.3 months (95% CI, 6.2-13.3 months) and median overall survival was 28.2 months (95% CI, 16-36.4 months). Symptomatic grade 3 cardiotoxicity occurred in 15% of cases and febrile neutropenia in 47% of the patients. CONCLUSIONS The combination of NPLD and docetaxel demonstrated high antitumour activity in a population of metastatic breast cancer patients exposed to adjuvant anthracyclines and showed an unexpected and unexplained 15% symptomatic left ventricular systolic dysfunction rate.

Abstract
We revealed that pre-treatment with docetaxel (DOC) 12 h before adriamycin (ADR) administration significantly reduced ADR-induced toxic death compared with the simultaneous dosing schedule that was commonly used in previous studies. We considered that pre-treatment with DOC relieves ADR-induced cardiotoxicity. In this study, we investigated the influence of DOC on the pharmacokinetics and pharmacodynamics of ADR in order to clarify the mechanism by which DOC pre-treatment relieves ADR-induced cardiotoxicity. When ADR and/or DOC was intravenously administered, the DOC pre-treatment (DOC-ADR) group showed significantly less toxic death than the ADR-alone group. We examined hepatopathy, nephropathy, leukopenia, and cardiotoxicity, all of which can cause toxic death. Of these toxicities, ADR-induced cardiotoxicity was significantly relieved in the DOC-ADR group. To elucidate the mechanism by which DOC pre-treatment relieved ADR-induced cardiotoxicity, lipid peroxidation as a proxy for the free radical level and the pharmacokinetics of ADR were measured. There was no difference in the pharmacokinetics of ADR between the ADR and DOC-ADR groups. On the other hand, the DOC-ADR group showed significantly inhibited lipid peroxidation in the heart compared with the ADR group. It was considered that DOC pre-administration inhibited ADR-induced free radicals and decreased cardiotoxicity.

Abstract
Chemotherapy-induced neutropenia is a major risk factor for infection-related morbidity and mortality and also a significant dose-limiting toxicity in cancer treatment. Patients developing severe (grade 3/4) or febrile neutropenia (FN) during chemotherapy frequently receive dose reductions and/or delays to their chemotherapy. This may impact the success of treatment, particularly when treatment intent is either curative or to prolong survival. In Europe, prophylactic treatment with granulocyte-colony stimulating factors (G-CSFs), such as filgrastim (including approved biosimilars), lenograstim or pegfilgrastim is available to reduce the risk of chemotherapy-induced neutropenia. However, the use of G-CSF prophylactic treatment varies widely in clinical practice, both in the timing of therapy and in the patients to whom it is offered. The need for generally applicable, European-focused guidelines led to the formation of a European Guidelines Working Party by the European Organisation for Research and Treatment of Cancer (EORTC) and the publication in 2006 of guidelines for the use of G-CSF in adult cancer patients at risk of chemotherapy-induced FN. A new systematic literature review has been undertaken to ensure that recommendations are current and provide guidance on clinical practice in Europe. We recommend that patient-related adverse risk factors, such as elderly age (≥65 years) and neutrophil count be evaluated in the overall assessment of FN risk before administering each cycle of chemotherapy. It is important that after a previous episode of FN, patients receive prophylactic administration of G-CSF in subsequent cycles. We provide an expanded list of common chemotherapy regimens considered to have a high (≥20%) or intermediate (10-20%) risk of FN. Prophylactic G-CSF continues to be recommended in patients receiving a chemotherapy regimen with high risk of FN. When using a chemotherapy regimen associated with FN in 10-20% of patients, particular attention should be given to patient-related risk factors that may increase the overall risk of FN. In situations where dose-dense or dose-intense chemotherapy strategies have survival benefits, prophylactic G-CSF support is recommended. Similarly, if reductions in chemotherapy dose intensity or density are known to be associated with a poor prognosis, primary G-CSF prophylaxis may be used to maintain chemotherapy. Clinical evidence shows that filgrastim, lenograstim and pegfilgrastim have clinical efficacy and we recommend the use of any of these agents to prevent FN and FN-related complications where indicated. Filgrastim biosimilars are also approved for use in Europe. While other forms of G-CSF, including biosimilars, are administered by a course of daily injections, pegfilgrastim allows once-per-cycle administration. Choice of formulation remains a matter for individual clinical judgement. Evidence from multiple low level studies derived from audit data and clinical practice suggests that some patients receive suboptimal daily G-CSFs; the use of pegfilgrastim may avoid this problem.

Abstract
To compare the long-term outcome of women with primary or locally advanced breast cancer randomised to receive either doxorubicin and cyclophosphamide (AC) or doxorubicin and docetaxel (AD) as primary chemotherapy. Eligible patients with histologic-proven breast cancer with primary tumours > or = 3 cm, inflammatory or locally advanced disease, and no evidence of distant metastases, were randomised to receive a maximum of 6 cycles of either doxorubicin (60 mg/m(2)) plus cyclophosphamide (600 mg/m(2)) i/v or doxorubicin (50 mg/m(2)) plus docetaxel (75 mg/m(2)) i/v every 3 weeks, followed by surgery on completion of chemotherapy. Clinical and pathologic responses have previously been reported. Time to relapse, site of relapse, and all-cause mortality were recorded. This updated analysis compares long-term disease-free (DFS) and overall survival (OS) using stratified log rank methods. A total of 363 patients were randomised to AC (n = 181) or AD (n = 182). A complete pathologic response was observed in 16% for AC and 12% for AD (P = 0.43). The number of patients with positive axillary nodes at surgery with AC was 61% and AD 66% (P = 0.36). At a median follow-up of 99 months there is no significant difference between the two groups for DFS (P = 0.20) and OS (P = 0.24). Deaths were due to metastatic breast cancer in 96% of patients. Our data do not support a clinical benefit for simultaneous administration of AD compared with AC. However, the data do not exclude a smaller benefit than the study was powered to detect and are consistent with an increase in both disease-free and overall survival of about 5% for AD compared with AC. Outcome is consistent with the pathologic complete response following surgery.

Abstract
The pertinent literature on clinical studies comparing the respective value of myeloid colony stimulating factors to pegfilgrastim as a prevention of febrile neutropenia in chemotherapy-treated cancer patients has been reviewed. Pegfilgrastim is definitely not inferior to filgrastim or other myeloid colony stimulating agents with respect to duration of grade IV neutropenia and delivery of full chemotherapy dose on time; several comparative studies indicate a trend to less frequent febrile neutropenia with pegfilgrastim.

Abstract
Male breast cancer is an uncommon condition. It often occurs in settings in which there is an imbalance between androgens and oestrogens. Genetics plays an important role, as many cases are associated with mutations in BRCA2 or other genes. Male breast cancer occurs at an older age than female breast cancer and is frequently diagnosed at a later stage. Tumors are predominantly oestrogen and progesterone positive. Prognosis is approximately equivalent to that of breast cancer in females when matched for age, stage and hormonal receptors. The recommended treatment for male breast cancer is similar to that for breast cancer in postmenopausal females. However, the presence of androgens in males has a strong effect on the hormonal milieu and the ability of male patients to respond to hormonal agents. When pharmacologic treatment is required, tamoxifen is effective for first-line therapy. Other hormonal approaches such as orchiectomy, aromatase inhibitors and androgen ablation may be useful in later lines of therapy.

Abstract
PURPOSE The combination of doxorubicin and cyclophosphamide (AC) is a standard adjuvant regimen. Doxorubicin and docetaxel (AT) is one of the most active cytotoxic regimens for metastatic breast cancer. The purpose of this trial was to determine whether adjuvant AT improved disease-free survival compared with AC in operable breast cancer. PATIENTS AND METHODS Women with invasive breast cancer were eligible if there were one to three positive lymph nodes or if the node-negative tumor was greater than 1 cm. Patients were randomly assigned after surgery to receive doxorubicin (60 mg/m(2)) plus either cyclophosphamide (600 mg/m(2); AC) or docetaxel (60 mg/m(2); AT) given every 3 weeks for four cycles, followed by hormone therapy for patients with estrogen receptor (ER) and/or progesterone receptor (PR)-positive tumors. RESULTS There were 2,882 eligible patients enrolled. After a median follow-up of 79.5 months, there was no significant difference in disease-free survival (DFS; 85% in both arms) or overall survival (91% v 92%) at 5 years. The hazard ratio for AC versus AT was 1.02 (95% CI for DFS, 0.86 to 1.22; P = .78). In an exploratory analysis of prespecified stratification factors by ER and PR expression there were trends toward improved DFS for AT in ER/PR-negative disease. Grade 3 neutropenia associated with fever or infection occurred more often with AT (26% v 10%; P < .05). CONCLUSION AT did not improve DFS or overall survival in this population, and was associated with more toxicity.

Abstract
As reflected in its varied clinical behavior, appearances under the light microscope, and differential patterns of gene expression, metastatic breast cancer (MBC) is a heterogeneous disease. Systemic treatment decisions are guided by specific tumor characteristics and individual patient factors. For patients with hormone receptor (HR)-negative MBC and for those whose HR-positive disease has become refractory to hormonal therapies, cytotoxic chemotherapy has been the mainstay of systemic treatment. For hormone-insensitive, HER2-positive MBCs, the addition of trastuzumab to chemotherapy has resulted in improved outcomes. Hormone-insensitive MBC lacking HER2 overexpression includes the subset of patients with estrogen receptor/ progesterone receptor/HER2-negative (so-called triple-negative) disease, which represents a significant minority of all breast cancers. Therapeutic options for such patients are limited by the lack of specific targeted approaches, and this heterogeneous group will be considered collectively as well as separately in this overview of existing and emerging treatment strategies. Conventional cytotoxic chemotherapy, alone or in combination, has been the standard first-line treatment for patients with MBC not amenable to antiestrogen or trastuzumab therapy. The recent evaluation of new targeted therapies in combination with cytotoxic agents has created a new type of combination regimen. Agents targeting angiogenesis, the epidermal growth factor receptor, and various signal transduction pathways have been combined with chemotherapy and possess biologic activity in MBC. As these combinations are being investigated, parallel correlative studies aimed at enriching the population who will benefit most are under way.

Abstract
The impact of first- and subsequent-cycle growth factor use in the community setting has not been studied extensively. We conducted this large, prospective, noncomparative study to assess neutropenia and related complications in patients receiving myelotoxic chemotherapy with pegfilgrastim support in community practices. Patients > or = 18 years old with cancers other than leukemia or myelodysplastic syndrome, including those with major comorbidities, were eligible. Pegfilgrastim (6 mg) was to be administered approximately 24 hours after chemotherapy in all cycles (minimum, four cycles). A total of 2,112 patients was included in the analyses. The most common tumor types were breast cancer (46%), non-Hodgkin's lymphoma (15%), and non-small cell lung cancer (13%). Chemotherapies administered most often were a platinum plus a taxane (18%), and anthracycline plus an alkylating agent (18%), and a taxane plus an anthracycline plus an alkylating agent (16%). The percentage of patients with neutropenia-related hospitalization was 2.9% in cycle 1 and 5.6% across all cycles. Chemotherapy dose reductions and delays were attributed to neutropenia in 1.8% and 0.9% of patients, respectively, in cycle 2 and 2.9% and 2.1% of patients, respectively, across all cycles. Febrile neutropenia (absolute neutrophil count <1.0 x 10(9)/l with temperature > or = 38.2 degrees C) occurred in 3.6% of patients in cycle 1 and in 6.3% of patients across all cycles. The most frequently reported serious adverse events were febrile neutropenia (3.4%), neutropenia (2.6%), and dehydration (2.6%). Bone pain (0.1%) was the only related serious adverse event reported in more than one patient. Data from this community-based study suggest that patients undergoing chemotherapy benefit from pegfilgrastim support beginning in the first cycle of chemotherapy.

Abstract
BACKGROUND The aim of the study was to identify reliable predictive biological markers for treatment outcome following neoadjuvant adriamycin/docetaxel (AT) chemotherapy in locally advanced breast cancer patients. MATERIALS AND METHODS This study was a phase II study on AT neoadjuvant chemotherapy in locally advanced breast cancer patients. Patients received 50 mg/m(2) of doxorubicin intravenously (IV) over 15 min followed by docetaxel 75 mg/m(2) infused over 1 h, repeated every 3 weeks for three cycles. Surgery was performed within 3-4 weeks following the last cycle of chemotherapy. We analyzed the pre-treatment and post-treatment expression levels of ER, PgR, HER-2, Ki-67 proliferation index, and p53 and examined the correlation between the markers and clinical parameters with treatment response, overall survival and relapse-free survival following neoadjuvant treatment. RESULTS From July 2001 to September 2004, 61 patients were enrolled. The meaningful parameters adversely influencing survival were post-treatment ER(-) status (P = 0.013) and post-treatment Ki-67 index above 1.0% (P = 0.013). At the multivariate level, the post-treatment Ki-67 proliferation index < or = 1.0 was the only meaningful prognostic factor for better survival (P = 0.033). Notably, tumors with Ki-67 index < or = 1.0 were more likely to express ER with statistical significance (P = 0.002). Tumors with ER(+) and Ki-67 index < or = 1.0 showed the highest survival rate, followed by ER(+) and Ki-67 index > 1.0%, ER(-) and Ki-67 < or = 1.0%, and ER(-) and Ki-67 > 1.0% with the worst survival (P = 0.033). CONCLUSION Collectively, post-treatment ER status and Ki-67 proliferation index were prognostic of overall survival following neoadjuvant AT chemotherapy.

Abstract
Over the past decade the taxanes have proved to be fundamental in the treatment of breast cancer. Initially found to have efficacy in metastatic breast cancer, the taxanes are now vital components in the treatment of early-stage disease, in which their addition to adjuvant treatment of early breast cancer has been shown to improve overall survival. In addition, the taxanes have demonstrated a role in first-line therapy for metastatic disease, with some of the highest efficacy of any class of chemotherapy. Targeted therapies in combination with the taxanes have further improved survival for both early and metastatic disease. New formulations of taxanes may both improve antitumor activity and reduce toxicity.

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
Doxorubicin is one of the most prescribed anticancer drugs, due to its important activity in hematological malignancies as in solid tumors. However, its important cardiac toxicity still limits its long-term use and prevents from reaching optimal benefits. Numerous ways have been proposed to avoid cardiac toxicity, such as protracted infusions or special formulations, development of less cardiotoxic analogues and of cardioprotectors. There is a need for preclinical models able to screen rapidly these various approaches and to provide rational bases for clinical trials. The first model is the long-term rabbit model. Weanling rabbits given weekly injections of doxorubicin for 4 months developed a cardiomyopathy which was obvious from a clinical (cardiac failure) and from a pathological point of view. This model has been widely used afterwards for the discovery of cardioprotective molecules. Models in other animals such as rats or mice were similarly implemented, also with long-term exposures to the drug, resulting in cardiac failure and severe pathological alterations which could be graded for comparison. Starting from the evidence that the damage caused by anthracyclines on cardiomyocytes was immediate after each injection and that the functional efficiency of the myocardium should be affected by the anthracyclines long before the morphological alterations become detectable, we developed a short-term model studying the cardiac performances of isolated perfused hearts of rats that had been treated within 12 days by repetitive administrations of the molecule(s) to be tested. This model appeared easy to implement and provided the data expected from clinical experience: epirubicin appeared less cardiotoxic than doxorubicin; liposomal formulations appeared less cardiotoxic than free drug formulations; dexrazoxane strongly protected against doxorubicin cardiotoxicity. We were then to show that paclitaxel could potentiate doxorubicin cardiotoxicity, but that docetaxel did not so; or that a high dose of dexrazoxane brought significantly higher protection than a conventional dose. Based upon these various contributions, we can encourage the use of the short-term model of isolated perfused rat heart to screen the preclinical cardiotoxicity of anthracycline molecules, formulations and combinations.

Abstract
OBJECTIVE The primary aim of this study was to estimate the rate of clinical and pathologic response to preoperative docetaxel, doxorubicin, and infusional 5-fluorouracil in patients with locally advanced breast cancer. Secondary objective included the determination of toxicity profile. PATIENTS AND METHODS Thirty-nine patients (median age 49 years) with histologically confirmed locally advanced breast cancer (stage IIIA or IIIB) were studied. Patients received 4 courses of chemotherapy with docetaxel (75 mg/m2 iv over 1 hour), doxorubicin (50 mg/m2 iv bolus), and 5-fluorouracil (300 mg/m2/d as continuous iv infusion on days 1-5). Treatment cycles were repeated every 21 days. Prophylactic filgastrim 5 microg/kg s/c QD was administered to all patients. Definitive surgery was performed after the completion of 4 cycles of therapy. Pathologic complete response was defined as the absence of invasive cancer in both the breast and ipsilateral axillary lymph nodes. RESULTS The clinical objective response rate (partial plus complete) was 87% (95% confidence interval [CI]: 76-98%). Three patients (8%) had complete pathologic response. Two patients progressed preoperatively. Thirteen patients (33%) developed neutropenic fever. Fifty-three percent of the patients were hospitalized for treatment related complications. No cardiotoxicity or treatment related deaths were observed. CONCLUSIONS Triple cytotoxic therapy based on concurrent doxorubicin and docetaxel with infusional 5-flourouracil (5-FU) does not appear to significantly improve the pathologic response in patients with locally advanced breast cancer.

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
Chemotherapy-induced neutropenia is not only a major risk factor for infection-related morbidity and mortality, but is also a significant dose-limiting toxicity in cancer treatment. Patients developing severe (grade 3/4) or febrile neutropenia (FN) during chemotherapy frequently receive dose reductions and/or delays to their chemotherapy. This may impact on the success of treatment, particularly when treatment intent is either curative or to prolong survival. The incidence of severe or FN can be reduced by prophylactic treatment with granulocyte-colony stimulating factors (G-CSFs), such as filgrastim, lenograstim or pegfilgrastim. However, the use of G-CSF prophylactic treatment varies widely in clinical practice, both in the timing of therapy and in the patients to whom it is offered. While several academic groups have produced evidence-based clinical practice guidelines in an effort to standardise and optimise the management of FN, there remains a need for generally applicable, European-focused guidelines. To this end, we undertook a systematic literature review and formulated recommendations for the use of G-CSF in adult cancer patients at risk of chemotherapy-induced FN. We recommend that patient-related adverse risk factors such as elderly age (>or=65 years), be evaluated in the overall assessment of FN risk prior to administering each cycle of chemotherapy. In addition, when using a chemotherapy regimen associated with FN in >20% patients, prophylactic G-CSF is recommended. When using a chemotherapy regimen associated with FN in 10-20% patients, particular attention should be given to patient-related risk factors that may increase the overall risk of FN. In situations where dose-dense or dose-intense chemotherapy strategies have survival benefits, prophylactic G-CSF support is recommended. Similarly, if reductions in chemotherapy dose intensity or density are known to be associated with a poor prognosis, primary G-CSF prophylaxis may be used to maintain chemotherapy. Finally, studies have shown that filgrastim, lenograstim and pegfilgrastim have clinical efficacy and we recommend the use of any of these agents to prevent FN and FN-related complications, where indicated.

Abstract
The most common chemotherapeutic agents in the treatment of breast cancer are anthracyclines and taxanes. The major dose-limiting toxicities associated with these agents are myelosuppression and associated febrile neutropenia (FN). FN can significantly impact the ability to deliver full-dose chemotherapy on schedule and as a result may increase the risk of disease recurrence and eventual disease-related mortality. The use of granulocyte colony stimulating factors (G-CSFs) significantly improves the management of FN, both in a therapeutic and in a prophylactic approach. Nevertheless, the high cost of these agents limits their widespread prophylactic use. Therefore, the identification of patients who are at a higher risk of developing FN and who will benefit from the prophylactic use of G-CSFs has become the subject of several clinical and cost-effectiveness studies. Recently, new data have been accumulated concerning the risk of FN in different chemotherapy regimens, and different risk models have been developed to assess the neutropenic risk with all its complications. This article reviews and summarizes cutting-edge, disease-specific data as well as national and international guidelines regarding the use of G-CSFs to prevent chemotherapy-induced FN, with focus on the treatment of breast cancer.

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
Granulocyte colony-stimulating factors such as filgrastim (Neupogen, Amgen, Inc.) and pegfilgrastim (Neulasta, Amgen, Inc.) are frequently used in clinical practice for the prevention of chemotherapy-induced neutropenia and its potentially life-threatening complications. Due to its unique neutrophil-mediated clearance, pegfilgrastim can be administered once per chemotherapy cycle. Clinical trials have shown that a single, fixed subcutaneous dose of pegfilgrastim 6 mg is comparable in safety and efficacy to daily injections of filgrastim for decreasing the incidence of infection following myelosuppressive chemotherapy in patients with cancer. Postregistrational trials have been conducted to evaluate the use of pegfilgrastim with emerging dose-dense regimens, in myeloid cancers and for mobilisation and engraftment of autologous stem cells. Ongoing clinical trials continue to explore further potential uses for pegfilgrastim.

Abstract
Neutropenia is the most important dose-limiting toxicity of myelotoxic chemotherapy. Current guidelines recommend primary prophylactic use of granulocyte colony stimulating factor (G-CSF) with chemotherapy regimens associated with an incidence of febrile neutropenia (FN) of at least 40% and in patients at high risk of infections, such as the elderly. Using prophylactic G-CSF support, planned chemotherapy doses are administered on time more frequently. Pegfilgrastim is a rationally designed recombinant human G-CSF with a sustained duration of action. A once-per-cycle 6-mg fixed dose of pegfilgrastim reduced the duration of severe neutropenia and the incidence of FN as efficiently as daily filgrastim in standard or dose-dense chemotherapy regimens in young and elderly patients with breast cancer, non-small-cell lung cancer and lymphomas. The safety profile of onceper- cycle pegfilgrastim is comparable with that of daily filgrastim. In conclusion, a fixed-dose of pegfilgrastim given once per cycle is a suitable substitute for body weight-based daily dosing of G-CSF, an improvement which should be particularly beneficial for outpatients receiving myelotoxic chemotherapy.

PurposeTo compare the efficacy and safety of doxorubicin and docetaxel (AT) with fluorouracil, doxorubicin, and cyclophosphamide (FAC) as first-line chemotherapy for metastatic breast cancer (MBC).Patients and MethodsPatients (n = 216) were randomly assigned to either AT (doxorubicin 50 mg/m2and docetaxel 75 mg/m2) or FAC (fluorouracil 500 mg/m2, doxorubicin 50 mg/m2, and cyclophosphamide 500 mg/m2); both regimens were administered on day 1, every 3 weeks.ResultsA median number of six cycles was delivered in both arms, with a median relative dose-intensity of more than 98%. Median time to progression (TTP) and median overall survival (OS) were significantly longer for patients on AT compared with FAC (TTP: 8.0 v 6.6 months, respectively; P = .004; and OS: 22.6 v 16.2 months, respectively; P = .019). The overall response rate (ORR) was significantly higher in patients on AT compared with FAC (58% v 37%, respectively; P = .003). The ORR on AT was also higher in patients with visceral disease compared with FAC patients with visceral disease (59% v 36%, respectively; P = .003). There were no differences in grade 3 to 4 neutropenia and infections (AT 89% v FAC 84% and AT 12% v FAC 9%, respectively). Neutropenic fever was more common in AT-treated patients than FAC-treated patients (33% v 9%, respectively; P < .001). Grade 3 to 4 nonhematologic toxicity was infrequent in both arms. Congestive heart failure was observed in 3% and 6% of patients on AT and FAC, respectively.ConclusionIn this phase II to III study, AT resulted in a significantly longer TTP and OS and a higher objective ORR than FAC. First-line AT is a valid treatment option for patients with 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 We conducted a phase I trial to determine the safety and maximum tolerated dose (MTD) of non-pegylated liposome-encapsulated doxorubicin (Myocet; D-99) administered with weekly docetaxel in metastatic breast cancer (MBC) patients. PATIENTS AND METHODS Twenty-one patients with no prior chemotherapy for MBC received D-99 (60 or 50 mg/m2) intravenously (i.v.) on day 1 and escalating doses of docetaxel (25, 30 and 35 mg/m2 i.v. on days 1 and 8 in cohorts of three to six patients. Treatment cycles were repeated every 21 days for a maximum of six cycles. RESULTS The maximum tolerated dose (MTD) was 50 mg/m2 of D-99 in combination with 25 mg/m2 of weekly docetaxel. The most common grade 4 toxicity was neutropenia that occurred in 42 (41%) of treatment cycles, with 10 hospitalizations for febrile neutropenia. Serious protocol-defined cardiac events occurred in three (14%) patients, with two (10%; 95% confidence interval [CI] 1% to 30%) developing congestive heart failure (CHF) after a total cumulative anthracycline dose (adjuvant doxorubicin + D-99) of 540 mg/m2. CONCLUSIONS D-99 in combination with weekly docetaxel, at the doses and schedule as administered in this trial, is not recommended for phase II testing. Additional trials, using different doses and schedules, are required to evaluate the potential side-effects and efficacy of D-99 and docetaxel.

Abstract
PURPOSE We evaluated the efficacy of pegfilgrastim to reduce the incidence of febrile neutropenia associated with docetaxel in breast cancer patients. PATIENTS AND METHODS Patients were randomly assigned to either placebo or pegfilgrastim 6 mg subcutaneously on day 2 of each 21-day chemotherapy cycle of 100 mg/m(2) docetaxel. The primary end point was the percentage of patients developing febrile neutropenia (defined as body temperature >/= 38.2 degrees C and neutrophil count < 0.5 x 10(9)/L on the same day of the fever or the day after). Secondary end points were incidence of hospitalizations associated with a diagnosis of febrile neutropenia, intravenous (IV) anti-infectives required for febrile neutropenia, and the ability to maintain planned chemotherapy dose on time. Patients with febrile neutropenia were converted to open-label pegfilgrastim in subsequent cycles. RESULTS Nine hundred twenty-eight patients received placebo (n = 465) or pegfilgrastim (n = 463). Patients receiving pegfilgrastim, compared with patients receiving placebo, had a lower incidence of febrile neutropenia (1% v 17%, respectively; P < .001), febrile neutropenia-related hospitalization (1% v 14%, respectively; P < .001), and use of IV anti-infectives (2% v 10%, respectively; P < .001). The percentage of patients receiving the planned dose on time was similar between patients receiving pegfilgrastim and patients who initially received placebo (80% and 78%, respectively), as would be expected of the study design. Pegfilgrastim was generally well tolerated and safe, and the adverse events reported were typical of this patient population. CONCLUSION First and subsequent cycle use of pegfilgrastim with a moderately myelosuppressive chemotherapy regimen markedly reduced febrile neutropenia, febrile neutropenia-related hospitalizations, and IV anti-infective use.

Abstract
PURPOSE This randomized, multicenter, phase III trial evaluated whether sequential doxorubicin and docetaxel (A-->T) reduced hematological toxicity, especially febrile neutropenia, compared with concomitant (AT) administration as first-line chemotherapy in metastatic breast cancer (MBC). PATIENTS AND METHODS One hundred forty-four patients were randomly assigned to receive three cycles of doxorubicin 75 mg/m(2) every 21 days followed by three cycles of docetaxel 100 mg/m(2), every 21 days (A-->T) or six cycles of the combination doxorubicin 50 mg/m(2) and docetaxel 75 mg/m(2) (AT) every 21 days. Patients previously treated with anthracyclines received two cycles of doxorubicin followed by four cycles of docetaxel (A-->T), or three cycles of AT followed by three cycles of docetaxel 100 mg/m(2) every 21 days. RESULTS Febrile neutropenia was less common in the A-->T arm (29.3% of patients, 6.9% of cycles) compared with the AT arm (47.8% of patients, 14.8% of cycles; P =.02 and P =.0004, respectively). Asthenia, diarrhea, and fever occurred more frequently in the AT arm. The overall responses rates were 61% in the A-->T arm (95% CI, 50% to 72%) and 51% in the AT arm (95% CI, 39% to 63%). The median duration of response was 8.7 months (A-->T) and 7.6 months (AT); the median time to progression was 10.5 months (A-->T) and 9.2 months (AT); the median overall survival was 22.3 months (A-->T) and 21.8 months (AT); and no significant differences were found. CONCLUSION A-->T significantly reduced febrile neutropenia compared with AT in MBC patients and maintains comparable antitumoral efficacy. A-->T represents a valid option for the treatment of MBC.

Abstract
Chemotherapy-induced neutropenia is a frequent complication in cancer patients receiving myelosuppressive chemotherapy. Chemotherapy-induced neutropenia can result in febrile neutropenia and potentially life-threatening infections requiring hospitalization and intravenous anti-infectives. Chemotherapy dose may be reduced or delayed as a result of chemotherapy-induced neutropenia, which can negatively impact treatment outcomes. Granulocyte colony-stimulating factors, such as filgrastim, stimulate neutrophil production and can therefore reduce the incidence and severity of chemotherapy-induced neutropenia. Filgrastim undergoes rapid renal clearance and needs to be administered daily. The development of pegfilgrastim represents a significant advance in the management of chemotherapy-induced neutropenia as the longer serum half-life allows once-per-chemotherapy administration, and evidence supports increased prophylactic effectiveness in reducing the incidence of febrile neutropenia. This paper reviews the development of pegfilgrastim and summarizes recent clinical data on the use of this simple, effective and well-tolerated option for the management of chemotherapy-induced neutropenia in patients with cancer.

Abstract
BACKGROUND The present study was designed with the aim of evaluating the tolerability and activity of pegylated liposomial doxorubicin (PLD) in combination with weekly docetaxel as first line treatment of advanced breast cancer. PATIENTS AND METHODS Fifty-seven patients entered the study. PLD was administered at escalating doses starting from 30 mg/m2, on day 1; docetaxel was administered at the fixed dose of 35 mg/m2 on days 2 and 9. A cycle of therapy consisted of 21 days. RESULTS The MTD was achieved at the dose of 40 mg/m2 of PLD, being febrile neutropenia and palmar-plantar-erythrodisesthesia (PPE) the dose-limiting toxicities (DLTs), so that the fixed dose of PLD for the Phase II study was 35 mg/m2. Forty-two consecutive patients received treatment at the established dose for a total of 194 cycles: among these, three patients were withdrawn for severe allergic reaction at the first administration of PLD. Hematological toxicity was moderate, the most common grade 1-3 non-hematological toxicities were stomatitis and PPE, occurring in 20 (47.5%) and 16 (38%) patients, respectively. No cardiac toxicity was recorded. According to the intent to treat analysis a major objective response was observed in 59.5% of patients (95% CI, 43.3-74.4%), with a median time to progression of 9 months and an estimated overall survival at 18 months of 62%. CONCLUSION The combination of PLD and weekly docetaxel is an effective first-line therapy for patients with advanced breast cancer. PPE and mucositis are the most relevant side effects of such a combination.
