Abstract
Background Combined neoadjuvant chemotherapy with trastuzumab and pertuzumab is the standard regimen for human epidermal growth receptor 2 (HER2)-positive breast cancer (BC). However, pertuzumab is not available because it is not on the market or covered by medicare in some regions or poor economy. Anthracyclines and taxanes are cornerstones in BC chemotherapy, and their combination contributes to satisfactory efficiency in neoadjuvant settings. Nonetheless, concomitant administration of trastuzumab and an anthracycline is generally avoided clinically due to cardiotoxicity. Pegylated liposomal doxorubicin (PLD) is less cardiotoxic compared with traditional anthracyclines. Here, we conducted this prospective study to evaluate the efficacy, safety, and potential biomarkers for PLD plus trastuzumab and docetaxel as neoadjuvant treatment in HER2-positive BC. Patients and Methods Patients with stage II or III HER2-positive BC were recruited in this multicenter, open-label, single-arm, phase II study. Eligible patients were given 6 cycles of PLD plus docetaxel and trastuzumab. Primary endpoint was total pathological complete response (tpCR, ypT0/is ypN0). Secondary endpoints were breast pathological complete response (bpCR, ypT0/is), objective response rate (ORR), operation rate, breast-conserving surgery rate, and safety. Metadherin (MTDH), glutaminyl-peptide cyclotransferase (QPCT), topoisomerase II alpha (TOP2A), programmed death ligand 1 (PD-L1), and tumor-infiltrating lymphocytes (TILs) were evaluated in BC tissues pre-neoadjuvant for potential biomarkers. Results Between March 2019 and February 2021, 54 patients were enrolled, 50 were included in the analysis, and 35 (70.0%) completed 6 cycles of neoadjuvant treatment. Forty-nine (98.0%) patients underwent surgery with a breast-conserving rate of 44.0%. The tpCR rate, bpCR rate, and ORR were 48.0% (95% CI, 33.7%–62.6%), 60.0% (95% CI, 45.2%–73.6%), and 84.0% (95% CI, 70.9%–92.8%), respectively. tpCR was associated with MTDH (p = 0.002) and QPCT (p = 0.036) expression but not with TOP2A (p = 0.75), PD-L1 (p = 0.155), or TILs (p = 0.76). Patients with HR-negative status were more likely to achieve bpCR compared with those with HR-positive status (76.2% vs. 48.3%, p = 0.047). Grade ≥3 adverse events occurred in 38.0% of patients. Left ventricular ejection fraction decline by ≥10% was reported in 18.0% of patients, and no patient experienced congestive heart failure. Conclusions PLD plus docetaxel and trastuzumab might be a potential neoadjuvant regimen for HER2-positive BC with a high tpCR rate and manageable tolerability. MTDH and QPCT are potential predictive markers for tpCR.

Abstract
Breast cancer (BC) is the second most common cancer in women globally after lung cancer. Presently, the most important approach for BC treatment consists of surgery, followed by radiotherapy and chemotherapy. The latter therapeutic methods are often unsuccessful in the treatment of BC because of their various side effects and the damage incurred to healthy tissues and organs. Currently, numerous nanoparticles (NPs) have been identified and synthesized to selectively target BC cells without causing any impairments to the adjacent normal tissues or organs. Based on an exploratory study, this comprehensive review aims to provide information on engineered NPs and their payloads as promising tools in the treatment of BC. Therapeutic drugs or natural bioactive compounds generally incorporate engineered NPs of ideal sizes and shapes to enhance their solubility, circulatory half-life, and biodistribution, while reducing their side effects and immunogenicity. Furthermore, ligands such as peptides, antibodies, and nucleic acids on the surface of NPs precisely target BC cells. Studies on the synthesis of engineered NPs and their impact on BC were obtained from PubMed, Science Direct, and Google Scholar. This review provides insights on the importance of engineered NPs and their methodology for validation as a next-generation platform with preventive and therapeutic effects against BC.

Abstract
Remarkable advances in nano delivery systems have provided new hope for tumor prevention, diagnosis and treatment. However, only limited clinical therapeutic effects against solid tumors were achieved. One of the main reasons is the presence of abundant physiological and pathological barriers in vivo that impair tumoral penetration and distribution of the nanodrugs. These barriers are related to the components of tumor microenvironment (TME) including abnormal tumor vasculature, rich composition of the extracellular matrix (ECM), and abundant stroma cells. Herein, we review the advanced strategies of TME remodeling to overcome these biological obstacles against nanodrug delivery. This review aims to offer a perspective guideline for the implementation of promising approaches to facilitate intratumoral permeation of nanodrugs through alleviation of biological barriers. At the same time, we analyze the advantages and disadvantages of the corresponding methods and put forward possible directions for the future researches.

Bispecific antibody (HER2 × mPEG) enhances anti-cancer effects by precise targeting and accumulation of mPEGylated liposomes. Acta Biomater 2020; 111:386-397. [PMID: 32417267 DOI: 10.1016/j.actbio.2020.04.029] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2019] [Revised: 04/13/2020] [Accepted: 04/14/2020] [Indexed: 12/17/2022]
Abstract
Targeted antibodies and methoxy-PEGylated nanocarriers have gradually become a mainstream of cancer therapy. To increase the anti-cancer effects of targeted antibodies combined with mPEGylated liposomes (mPEG-liposomes), we describe a bispecific antibody in which an anti-methoxy-polyethylene glycol scFv (αmPEG scFv) was fused to the C-terminus of an anti-HER2 (αHER2) antibody to generate a HER2 × mPEG BsAb that retained the original efficacy of a targeted antibody while actively attracting mPEG-liposomes to accumulate at tumor sites. HER2 ×mPEG BsAb can simultaneously bind to HER2-high expressing MCF7/HER2 tumor cells and mPEG molecules on mPEG-liposomal doxorubicin (Lipo-Dox). Pre-incubation of HER2 × mPEG BsAb with cells increased the endocytosis of Lipo-DiD and enhanced the cytotoxicity of Lipo-Dox to MCF7/HER2 tumor cells. Furthermore, pre-treatment of HER2 × mPEG BsAb enhanced the tumor accumulation and retention of Lipo-DiR 2.2-fold in HER2-high expressing MCF7/HER2 tumors as compared to HER2-low expressing MCF7/neo1 tumors. Importantly, HER2 × mPEG BsAb plus Lipo-Dox significantly suppressed tumor growth as compared to control BsAb plus Lipo-Dox in MCF7/HER2 tumor-bearing mice. These results indicate that HER2 × mPEG BsAb can enhance tumor accumulation of mPEG-liposomes to improve the therapeutic efficacy of combination treatment. Anti-mPEG scFv can be fused to any kind of targeted antibody to generate BsAbs to actively attract mPEG-drugs and improve anti-cancer efficacy. STATEMENT OF SIGNIFICANCE: Antibody targeted therapy and PEGylated drugs have gradually become the mainstream of cancer therapy. To enhance the anti-cancer effects of targeted antibodies combined with PEGylated drugs is very important. To this aim, we fused an anti-PEG scFv to the C-terminal of HER2 targeted antibodies to generate a HER2×mPEG bispecific antibody (BsAb) to retain the original efficacy of targeted antibody whilst actively attract mPEG-liposomal drugs to accumulate at tumor sites. The present study demonstrates pre-treatment of HER2×mPEG BsAb can enhance tumor accumulation of mPEG-liposomal drugs to improve the therapeutic efficacy of combination treatment. Anti-mPEG scFv can be fused to any kind of targeted antibody to generate BsAbs to actively attract mPEG-drugs and improve anti-cancer efficacy.

Abstract
Breast cancer (BC) is a highly prevalent disease, accounting for the second highest number of cancer-related mortalities worldwide. The anthracycline doxorubicin (DOX), isolated from Streptomyces peucetius var. caesius, is a potent chemotherapeutic drug that is successfully used to treat various forms of liquid and solid tumors and is currently approved to treat BC. DOX exerts its effects by intercalation into DNA and inhibition of topoisomerases I and II, causing damage to DNA and the formation of reactive oxygen species (ROS), resulting in the activation of caspases, which ultimately leads to apoptosis. Unfortunately, DOX also can cause cardiotoxicity, with patients only allowed a cumulative lifetime dose of 550 mg/m2. Efforts to decrease cardiotoxicity and to increase the blood circulation time of DOX led to the US Food and Drug Administration (FDA) approval of a PEGylated liposomal formulation (L-DOX), Doxil® (known internationally as Caelyx®). Both exhibit better cardiovascular safety profiles; however, they are not currently FDA approved for the treatment of metastatic BC. Here, we provide detailed insights into the mechanism of action of L-DOX and its most common side effects and highlight results of its use in clinical trials for the treatment of BC as single agent and in combination with other commonly used chemotherapeutics.

Abstract
Patients with HER2-positive breast cancer and brain metastases have limited treatment options, and, as a result of their poor performance status and worse prognosis, they are underrepresented in clinical trials. Not surprisingly, these patients may not be fit enough to receive any active treatment and are offered supportive therapy. BRCA2 mutations are reported to be rarely associated with HER2-overexpressing advanced breast cancer and even more rarely with brain metastases at diagnosis. We report on a BRCA2-positive breast cancer patient with metastatic disease in multiple sites, including the brain, and poor performance status who exhibited an extraordinary clinical and imaging response to the novel anti-HER2 therapy pertuzumab after multiple lines of therapy including anti-HER2 targeting. To our knowledge, the clinicopathologic and therapeutic characteristics of this patient point to a unique case and an urgent need for further investigation of pertuzumab in patients with brain metastases.

Abstract
Treatment for metastatic breast cancer still remains to be a challenge since the currently available diagnostic and treatment strategies fail to detect the micro-metastasis resulting in higher mortality rate. Moreover, the lack of specificity to target circulating tumor cells is also a factor. In addition, currently available imaging modalities to identify the secondaries vary with respect to various metastatic anatomic areas and size of the tumor. The drawbacks associated with the existing clinical management of the metastatic breast cancer demands the requirement of multifunctional nanotheranostics, which could diagnose at macro- and microscopic level, target the solid as well as circulating tumor cells and control further progression with the simultaneous evaluation of treatment response in a single platform. However, without the understanding of the biology as well as preferential homing ability of circulating tumor cells at distant organs, it is quite impossible to address the existing challenges in the present diagnostics and therapeutics against the breast cancer metastasis. Hence this review outlines the severity of the problem, basic biology and organ specificity with the sequential steps for the secondary progression of disease followed by the various mechanistic approaches in diagnosis and therapy at different stages.

Abstract
BACKGROUND CLEOPATRA is a phase 3 study to compare the efficacy and safety of pertuzumab, trastuzumab, and docetaxel with placebo, trastuzumab, and docetaxel in patients with HER2-positive first-line metastatic breast cancer. The results of the primary analysis showed significantly longer median progression-free survival in the pertuzumab group than in the placebo group. Interim analysis of overall survival favoured the pertuzumab group but was not significant. Here, we report results for overall survival after an additional year of follow-up. METHODS The study was a double-blind randomised trial undertaken at 204 centres in 25 countries. Patients with HER2-positive metastatic breast cancer who had not received previous chemotherapy or biological treatment for their metastatic disease were randomly assigned to receive either pertuzumab, trastuzumab, and docetaxel (n=402) or the same regimen with a matching placebo replacing pertuzumab (n=406). Randomisation was in a 1:1 ratio, stratified by geographical region and previous treatment status. The primary endpoint was progression-free survival (assessed independently), which has been reported previously; no follow-up data were gathered for the primary endpoint. Secondary endpoints included overall survival, progression-free survival (assessed by investigator), objective response rate, and safety. Median follow-up was 30 months in both groups. Efficacy endpoints were analysed in the intention-to-treat population and safety was analysed by treatment received. The study is completed but safety and survival data continue to be followed up. This trial is registered with ClinicalTrials.gov, number NCT00567190. FINDINGS In the intention-to-treat population, 267 patients died by data cutoff (May 14, 2012), 154 (38%) of 406 in the placebo group and 113 (28%) of 402 in the pertuzumab group. Median overall survival was 37.6 months (95% CI 34.3-NE [not estimable]) in the placebo group but had not been reached (95% CI 42.4-NE) in the pertuzumab group (hazard ratio 0.66, 95% CI 0.52-0.84; p=0.0008). Investigator-assessed median progression-free survival was 12.4 months (95% CI 10.4-13.5) in the placebo group and 18.7 months (16.6-21.6) in the pertuzumab group (hazard ratio 0.69, 95% CI 0.58-0.81). Serious adverse events were reported in 115 (29%) of 396 patients who received placebo, trastuzumab, and docetaxel and 148 (36%) of 408 who received pertuzumab, trastuzumab, and docetaxel, and included febrile neutropenia, neutropenia, diarrhoea, pneumonia, and cellulitis. Overall, adverse events were similar to those reported at the primary analysis with respect to frequency, severity, and specificity. INTERPRETATION Our analysis shows a significant improvement in overall survival with pertuzumab, trastuzumab, and docetaxel in patients with HER2-positive metastatic breast cancer, compared with placebo, trastuzumab, and docetaxel. Since this effect was not achieved at the expense of adverse events, this regimen represents a substantial improvement on the standard of care for this population of patients.

Abstract
Drug delivery systems can provide enhanced efficacy and/or reduced toxicity for anticancer agents. Liposome drug delivery systems are able to modify the pharmacokinetics and biodistribution of cytostatic agents, increasing the concentration of the drug released to neoplastic tissue and reducing the exposure of normal tissue. Anthracyclines are a key drug in the treatment of both metastatic and early breast cancer, but one of their major limitations is cardiotoxicity. One of the strategies designed to minimize this side effect is liposome encapsulation. Liposomal anthracyclines have achieved highly efficient drug encapsulation and they have proven to be effective and with reduced cardiotoxicity, as a single agent or in combination with other drugs for the treatment of either anthracyclines-treated or naïve metastatic breast cancer patients. Of particular interest is the use of the combination of liposomal anthracyclines and trastuzumab in patients with HER2-overexpressing breast cancer. In this paper, we discuss the different studies on liposomal doxorubicin in metastatic and early breast cancer therapy.

Abstract
Trastuzumab is a humanized monoclonal antibody against the extracellular domain of hEGF receptor-2 (HER2). Trastuzumab in combination with chemotherapy has proven efficacy in treating both early and metastatic HER2-positive breast cancer. In the metastatic setting, the addition of trastuzumab to chemotherapy is associated with a statistically significant longer time to disease progression, higher rate of objective response and improvement in overall survival. Trastuzumab efficacy is not influenced by hormone receptor status, but differences in median overall survival exist between HER2-positive and HER2-negative states. Reassessment of the benefit of re-exposing patients with metastatic breast cancer to trastuzumab following relapse in the adjuvant setting is necessary. Ongoing research into new HER2-targeted therapies and trials involving combination anti-HER2 drug therapy without chemotherapy show promise. This review is focused on the available results obtained with the use of trastuzumab in the subset of HER2-positive breast cancer patients with metastatic disease.

Abstract
Breast cancer is one of the most common cancers in women worldwide and metastasis is the major cause of breast cancer death. Development of new therapeutic agents for inhibiting breast cancer metastasis is therefore an urgent need. We previously demonstrated that recombinant DNA-derived viral capsid protein VP1 (rVP1) of foot-and-mouth disease virus-induced apoptosis of MCF-7 breast cancer cells in vitro. Here, we investigated whether rVP1 exhibits any inhibitory effects on migration/metastasis and human epidermal growth factor receptor 2 (HER-2), a well-known biomarker for poor prognosis of breast cancer. The effects of rVP1 on cancer cell migration/invasion and metastasis were evaluated using Transwell migration assay and animal cancer models of metastasis. Western blotting, RT-PCR, flow cytometry, immunohistochemistry, and immunofluorescence staining techniques were used to investigate the effects of rVP1 on HER-2 and signal transduction mediators. Non-cytotoxic concentrations of rVP1-induced mesenchymal-epithelial transition and significantly suppressed AP-2α and HER-2 expression as well as the migration and invasion of a variety of breast cancer cell lines in a β1-integrin-dependent manner in vitro. Gross and histopathologic examinations showed that rVP1 also suppressed metastasis of several breast cancer cell lines, including HER-2-overexpressing SK-BR-3 and BT-474 cells to lung, liver, or peripheral lymph node in orthotopic allograft/xenograft murine models. In addition, rVP1 significantly prolonged survival in breast cancer-bearing mice. Notably, no apparent side effects of rVP1 were detected, as shown by normal complete blood count levels and serum biochemistry profiles, including AST, ALT, BUN, and creatine. This study demonstrates that rVP1 suppresses the migration, invasion, and metastasis of breast cancer cells via binding to β1 integrin receptor and down-regulation of AP-2α and HER-2 expression. The effectiveness of rVP1 on inhibiting migration/metastasis of breast cancer and HER-2 expression suggests that it may be suitable for serving as potential therapeutics for metastatic breast cancer particularly HER-2-overexpressing cancer.

Abstract
BACKGROUND We determined the objective response rates produced by pegylated liposomal doxorubicin (PLD) plus carboplatin with/without trastuzumab (Herceptin). PATIENTS AND METHODS Patients with measurable disease were stratified by taxane treatment history and human epidermal growth factor receptor-2 status. TREATMENT PLD 30 mg/m(2) followed by carboplatin, day 1 of each 28-day cycle; human epidermal growth factor receptor-2 (HER2)-positive patients also received trastuzumab. RESULTS Arm 1 received PLD plus carboplatin (N = 41 arm 1a, taxane naive; N = 42 arm 1b, taxane pretreated); Arm 2 patients received PLD plus carboplatin + Herceptin (N = 46). Overall response rates: 31%, 31%, and 56%, respectively. Median overall survival durations were not reached in arm 1a and were 13 and 33 months for arms 1b and 2. Median progression-free survival: 8, 5, 10 months, respectively. Grades 3-4 treatment-related toxic effects for arms 1a, 1b, 2, respectively, were neutropenia 22%, 31%, 35%; thrombocytopenia 34%, 26%, 17%; and fatigue 2%, 14%, 13%. CONCLUSIONS PLD plus carboplatin has moderate antitumor activity and excellent tolerability. Herceptin and PLD plus carboplatin in HER2-positive patients have antitumor activity without significant cardiac toxicity. Toxicity results suggest that PLD can be combined with Herceptin with minimal cardiac toxicity.

Abstract
PURPOSE Prognostic impact of nodal status or lymphadenectomy in advanced ovarian cancer is still unclear. Known best prognostic impact in advanced ovarian cancer has the residual tumor mass. The aim of this retrospective study is to examine the importance of nodal status in correlation with residual tumor mass. METHODS One hundred and fifty-seven consecutive patients with primary stage III ovarian cancer underwent surgery between 01/2000 and 06/2007 at the Department of gynecology and obstetrics, University Hospital, Tübingen, Germany. All patients got stage-related surgery and platin-based chemotherapy. Median follow-up time was 53.5 months, and all patients were included in the study. RESULTS Resection status and nodal status are significant prognostic factors in our study (P < 0.001). In FIGO III, patients without residual tumor (R0) had significant best OS and PFS independent to node status (N0/N+; P = 0.002) compared to patients with residual tumor. In contrast, node status had significant positive impact on PFS in patients without residual tumor and node negativity. With the increase in residual tumor, the influence of lymphnode metastases on prognosis is decreasing. CONCLUSION Main intention of primary surgery is R0 resection with best prognosis in advanced stages. A systematic lymphadenectomy in cases with R0 resection or residual tumor <1 cm seems to be reasonable with positive impact on prognosis. Node status has impact on prognosis in patients with negative node after R0 resection with best PFS in FIGO III. Further prospective studies had to show whether systematic lymphadenectomy in suboptimally tumor-reduced patients can improve prognosis.

Kinetic targeting of pegylated liposomal doxorubicin: a new approach to reduce toxicity during chemotherapy (CARL-trial). BMC Cancer 2011; 11:337.

Abstract
BACKGROUND The therapeutic success of chemotherapeutic agents is often limited by severe adverse effects. To reduce toxicity of these drugs, nanoscale particle-based drug delivery systems (DDS) are used. DDS accumulate to some extent in tumor tissues, but only a very small portion of a given dose reaches this target. Accumulation of DDS in tumor tissues is supposed to be much faster than in certain other tissues in which side effects occur ("Kinetic Targeting"). Once saturation in tumor tissue is achieved, most of the administered DDS still circulate in the plasma. The extracorporeal elimination of these circulating nanoparticles would probably reduce toxicity. METHODS For the CARL-trial (Controlled Application and Removal of Liposomal chemotherapeutics), pegylated liposomal doxorubicin (PLD) was used as chemotherapeutic agent and double filtration plasmapheresis (DFPP) was performed for extracorporeal elimination of liposomes. PLD was given as 40 mg/m2 every 3 weeks in combination with vinorelbine 2 × 25 mg/m2 (neoadjuvant treatment of breast cancer, 12 patients), or as 40 mg/m2 every 4 weeks (recurrent ovarian cancer, 3 patients). Primary endpoints were the efficiency and safety profile of DFPP, and secondary endpoints were side effects and tumor response. RESULTS DFPP eliminated ~62% of circulating PLD, corresponding to ~45% of the total dose (n = 57 cycles). AUC of doxorubicin was reduced by 50%. No leakage of doxorubicin was detected during elimination, and no relevant DFPP-related side effects occurred. Reduction in tumor size > 30% occurred in 10/12 (neoadjuvant) and in 1/3 patients (recurrent). Only five grade 2 events and one grade 3 event (mucositis, neutropenia or leucopenia) and a single palmar-plantar erythrodysesthesia grade 2 were reported. CONCLUSION Extracorporeal elimination of PLD by DFPP is safe and efficient. CARL can diminish the main dose-limiting side effects of PLD, and probably many different DDS alike.

Abstract
INTRODUCTION Anthracyclines are widely prescribed anticancer agents that cause a dose-related cardiotoxicity, often aggravated by nonanthracycline chemotherapeutics or new generation targeted drugs. Anthracycline cardiotoxicity may occur anytime in the life of cancer survivors. Understanding the molecular mechanisms and clinical correlates of cardiotoxicity is necessary to improve the therapeutic index of anthracyclines or to identify active, but less cardiotoxic analogs. AREAS COVERED The authors review the pharmacokinetic, pharmacodynamic and biochemical mechanisms of anthracycline cardiotoxicity and correlate them to clinical phenotypes of cardiac dysfunction. Attention is paid to bioactivation mechanisms that converted anthracyclines to reactive oxygen species (ROS) or long-lived secondary alcohol metabolites. Preclinical aspects and clinical implications of the "oxidative stress" or "secondary alcohol metabolite" hypotheses are discussed on the basis of literature that cuts across bench and evidence-based medicine. Interactions of anthracyclines with comorbidities or unfavorable lifestyle choices were identified as important cofactors of the lifetime risk of cardiotoxicity and as possible targets of preventative strategies. EXPERT OPINION Anthracycline cardiotoxicity is a multifactorial process that needs to be incorporated in a translational framework, where individual genetic background, comorbidities, lifestyles and other drugs play an equally important role. Fears for cardiotoxicity should not discourage from using anthracyclines in many oncologic settings. Cardioprotective strategies are available and should be used more pragmatically in routine clinical practice.

Abstract
BACKGROUND In order to determine the feasibility of substituting pegylated liposomal doxorubicin (PLD) for doxorubicin in combination with cyclophosphamide and trastuzumab as adjuvant therapy, we conducted a phase II study of the combination as first-line therapy in human epidermal growth factor receptor 2 (HER2) overexpressing metastatic breast cancer (MBC). METHODS PLD 50 mg/m(2) and cyclophosphamide 600 mg/m(2) were administered every 4 weeks for six cycles; trastuzumab (4 mg/kg loading dose, then 2 mg/kg) was administered weekly for 24 weeks. The primary end point was objective response rate (ORR), and the secondary end points included time to progression (TTP), overall survival (OS), and safety. RESULTS Among the 48 evaluable patients, ORR was 68.8% [95% confidence interval (CI) 55.69% to 81.91%], with 6 patients (12.5%) achieving a complete response and 27 (56.2%) a partial response. The median TTP was 12 months (95% CI 9-15.1 months), and the median OS was 34.2 months (95% CI 27.2-41.2 months). Febrile neutropenia was seen in three patients, grade 3 hand-foot syndrome in 29.2% of patients, and grade 3-4 mucositis in 22.9% of patients. Symptomatic congestive heart failure was not observed, and 16.7% of patients experienced grade 2 asymptomatic left ventricular systolic dysfunction. CONCLUSION The combination of PLD-cyclophosphamide-concurrent trastuzumab is a feasible, safe, and effective first-line regimen for HER2-overexpressing MBC.

Abstract
BACKGROUND Pegylated liposomal doxorubicin (PLD) was shown as active but less toxic compared to doxorubicin in advanced breast cancer. Given its low cardiotoxicity, the combination of PLD and trastuzumab appears most attractive in the treatment of human epidermal factor receptor 2 (HER2)-positive breast cancer. PATIENTS AND METHODS We investigated the activity of 8 courses of PLD in combination with cisplatin and infusional 5-fluorouracil (CCF) plus 3-week trastuzumab in patients with primary or recurrent cT2-T4 a-d, N0-3, M0 any estrogen receptor (ER), HER2-positive breast cancer. Patients with ER and/or progesterone receptor (PgR) ≥ 10% tumors received also letrozole (plus triptorelin if premenopausal). The principal endpoint was clinical response rate; secondary endpoints were the pathologic complete response rate (pCR) and the cardiac safety of the combination. RESULTS Thirty-two patients were enrolled in the study and all are evaluable for response and toxicity. Fifteen patients (47%) had ER-positive tumors, 15 patients and 2 patients had ER absent and ER poor tumors, respectively. Thirteen patients (41%) had inflammatory breast cancer (IBC) and 84% of patients had clinically positive nodes. A clinical response rate of 94% (95% CI, 79%-99%) and a pCR rate of 41% (95% CI, 24%-59%) were observed. Fifty-four percent of patients with IBC obtained a pCR. Eleven patients discontinued treatment before completing 8 courses as planned. No patient developed relevant cardiac toxicity. CONCLUSION In this series of very locally advanced breast cancer, the combination of CCF and trastuzumab was very active obtaining an impressive rate of pCR, particularly in IBC, which merits further investigation in larger series.

Abstract
Anthracyclines have probably been considered to be the most active agents for the treatment of breast cancer and some other solid tumors and hematological malignancies. However, they are associated with dose-related cardiotoxicity, which can lead to progressive myocardial damage and limits the maximal cumulative dose that can be given. This review focuses on the non-pegylated liposome-encapsulated doxorubicin (Myocet®), which has been developed to increase the therapeutic index of free doxorubicin. The encapsulation of doxorubicin within a macromolecular vector, such as a liposome ("nanoparticle based drug delivery system") reduces its distribution volume, diminishing its toxicity for healthy tissues while increasing the concentration within the neoplastic tissue. The most common adverse event is neutropenia, which is consistent with previous experience with free doxorubicin. Available evidence suggests that the incidence of hematological toxicity is lower than with conventional doxorubicin. Myocet® both as a single agent and in combination is effective and safe with an associated reduction in incidence and severity of cardiac events. Nagykálnai T.

Abstract
Breast cancer is a major health issue in developed countries. Overexpression of HER2, a member of epidermal growth factor receptor family, occurs in 20%-30% of breast cancers. HER2 drives the cancer cells to develop a more aggressive phenotype, to metastasize to viscera and central nervous system, and to be less sensitive to chemotherapeutic agents. Trastuzumab (Herceptin®) is a monoclonal antibody directed against the extracellular domain of HER2. As single agent or with chemotherapy, trastuzumab improves survival of HER2-positive breast cancers. In the past years, trastuzumab has completely revolutionized the scenario of the treatment of HER2-positive breast cancer, representing one of the most remarkable examples of targeted therapy in oncology. However, issues such as the best chemotherapeutic companion to associate with trastuzumab, cardiac toxicities, and clinical resistance still require tremendous efforts by researchers. Here, we review pharmacology, efficacy studies, and toxicities of trastuzumab in metastatic breast cancer. Moreover, we provide some insights on resistance to therapy. Finally, we briefly discuss trastuzumab's place in the clinical setting.

Abstract
Novel therapies are emerging for treatment of patients with localized or advanced breast cancer. Targeted therapies such as trastuzumab, lapatinib, and bevacizumab have demonstrated significant clinical benefit in the metastatic setting, and trastuzumab has also improved patient outcome as adjuvant therapy in HER2+ breast cancer. Novel chemotherapies are also being developed to improve drug delivery, enhance efficacy, or decrease drug toxicity. These novel cytotoxic agents are being combined with established targeted therapies and are showing early promise for the treatment of patients with advanced breast cancer. Finally, new targeted therapies have shown clinical benefit, either as single agents or in combination with established targeted therapy or chemotherapy.

Abstract
This article examines how discouraging the use of anthracyclines in combination with trastuzumab in patients with human epidermal growth factor receptor 2 positive metastatic breast cancer because of fears of cardiotoxicity has influenced the use of these agents in this patient setting. Anthracyclines are among the most active drugs in breast cancer. Because of excessive cardiotoxicity, their use in combination with trastuzumab has been discouraged in patients with human epidermal growth factor receptor (HER)-2+ metastatic breast cancer. We sought to describe how this treatment paradigm influenced the use of anthracyclines in this patient setting. We analyzed a multi-institutional database containing the treatment history of 450 patients who received at least one trastuzumab-based regimen for HER-2+ metastatic breast cancer. Patients were considered eligible for anthracyclines for metastatic disease if they were never exposed (NE) or had been previously exposed (PE) to an anthracycline in the neoadjuvant or adjuvant setting and had relapsed after 12 months from the last dose. We then assessed the use of anthracycline-based therapy after failure with the first trastuzumab-based regimen in eligible patients. Three-hundred twenty-one patients were considered eligible for anthracyclines. In total, 190 eligible patients developing disease progression during the initial trastuzumab-based therapy were analyzed. An anthracycline was administered as first salvage treatment in 14 NE and two PE patients. Another 15 NE and nine PE patients received an anthracycline as a further line of therapy. Of 119 eligible patients who died from breast cancer, only 30 received an anthracycline for metastatic disease. In conclusion, despite the fact that two thirds of the patients receiving trastuzumab-based therapy for HER-2 metastatic breast cancer are eligible for anthracyclines, these drugs are infrequently used nowadays to treat trastuzumab-refractory disease. A role for these compounds should be redefined in this patient subset.

Abstract
The purpose of this trial was to determine cardiac toxicity and overall efficacy of the pegylated liposome doxorubicin (PLD)-docetaxel couplet alone if HER2-negative metastatic breast cancer (internal control) or with trastuzumab if HER2-positive disease. Upon central HER2 confirmation, 84 eligible patients received induction with PLD (30 mg/m(2)) and docetaxel (60 mg/m(2)) every 3 weeks (maximum eight cycles), alone if HER2-negative (arm A; N = 38) or plus trastuzumab (4 mg/kg once, then 2 mg/kg weekly) if HER2-positive disease (arm B; N = 46) as first-line therapy. Maintenance therapy (without PLD) allowed. Primary objectives were to determine whether congestive heart failure (CHF) rate >3% and the efficacy/toxicity of each arm. CHF rate was <3% in each arm. Response rate, median progression-free-, and overall survival in arms A and B were 47.4 and 45.7%, 11 and 10.6 months, and 24.6 and 31.8 months, respectively. Trastuzumab arm was associated with higher rates of hand foot syndrome (grade 3: 22 vs. 38%; P = 0.16; overall 51 vs. 75%, P = 0.03) and treatment discontinuation due to toxicity/patient withdrawal (13 vs. 28%; P = 0.11). Febrile neutropenia occurred in approximately 10% of patients. In conclusion, concurrent administration of trastuzumab with PLD-docetaxel was not associated with higher risk of cardiac toxicity compared with PLD-docetaxel alone, but led to excessive hand-foot syndrome.
