Abstract

Background The administration of endocrine therapy for 5 years substantially reduces recurrence rates during and after treatment in women with early-stage, estrogen-receptor (ER)–positive breast cancer. Extending such therapy beyond 5 years offers further protection but has additional side effects. Obtaining data on the absolute risk of subsequent distant recurrence if therapy stops at 5 years could help determine whether to extend treatment. Methods In this meta-analysis of the results of 88 trials involving 62,923 women with ER-positive breast cancer who were disease-free after 5 years of scheduled endocrine therapy, we used Kaplan–Meier and Cox regression analyses, stratified according to trial and treatment, to assess the associations of tumor diameter and nodal status (TN), tumor grade, and other factors with patients’ outcomes during the period from 5 to 20 years. Results Breast-cancer recurrences occurred at a steady rate throughout the study period from 5 to 20 years. The risk of distant recurrence was strongly correlated with the original TN status. Among the patients with stage T1 disease, the risk of distant recurrence was 13% with no nodal involvement (T1N0), 20% with one to three nodes involved (T1N1–3), and 34% with four to nine nodes involved (T1N4–9); among those with stage T2 disease, the risks were 19% with T2N0, 26% with T2N1–3, and 41% with T2N4–9. The risk of death from breast cancer was similarly dependent on TN status, but the risk of contralateral breast cancer was not. Given the TN status, the factors of tumor grade (available in 43,590 patients) and Ki-67 status (available in 7692 patients), which are strongly correlated with each other, were of only moderate independent predictive value for distant recurrence, but the status regarding the progesterone receptor (in 54,115 patients) and human epidermal growth factor receptor type 2 (HER2) (in 15,418 patients in trials with no use of trastuzumab) was not predictive. During the study period from 5 to 20 years, the absolute risk of distant recurrence among patients with T1N0 breast cancer was 10% for low-grade disease, 13% for moderate-grade disease, and 17% for high-grade disease; the corresponding risks of any recurrence or a contralateral breast cancer were 17%, 22%, and 26%, respectively. Conclusions After 5 years of adjuvant endocrine therapy, breast-cancer recurrences continued to occur steadily throughout the study period from 5 to 20 years. The risk of distant recurrence was strongly correlated with the original TN status, with risks ranging from 10 to 41%, depending on TN status and tumor grade.

Abstract

BACKGROUND: Neoadjuvant chemotherapy (NACT) for early breast cancer can make breast-conserving surgery more feasible and might be more likely to eradicate micrometastatic disease than might the same chemotherapy given after surgery. We investigated the long-term benefits and risks of NACT and the influence of tumour characteristics on outcome with a collaborative meta-analysis of individual patient data from relevant randomised trials. METHODS: We obtained information about prerandomisation tumour characteristics, clinical tumour response, surgery, recurrence, and mortality for 4756 women in ten randomised trials in early breast cancer that began before 2005 and compared NACT with the same chemotherapy given postoperatively. Primary outcomes were tumour response, extent of local therapy, local and distant recurrence, breast cancer death, and overall mortality. Analyses by intention-to-treat used standard regression (for response and frequency of breast-conserving therapy) and log-rank methods (for recurrence and mortality). FINDINGS: Patients entered the trials from 1983 to 2002 and median follow-up was 9 years (IQR 5-14), with the last follow-up in 2013. Most chemotherapy was anthracycline based (3838 [81%] of 4756 women). More than two thirds (1349 [69%] of 1947) of women allocated NACT had a complete or partial clinical response. Patients allocated NACT had an increased frequency of breast-conserving therapy (1504 [65%] of 2320 treated with NACT vs 1135 [49%] of 2318 treated with adjuvant chemotherapy). NACT was associated with more frequent local recurrence than was adjuvant chemotherapy: the 15 year local recurrence was 21·4% for NACT versus 15·9% for adjuvant chemotherapy (5·5% increase [95% CI 2·4-8·6]; rate ratio 1·37 [95% CI 1·17-1·61]; p=0·0001). No significant difference between NACT and adjuvant chemotherapy was noted for distant recurrence (15 year risk 38·2% for NACT vs 38·0% for adjuvant chemotherapy; rate ratio 1·02 [95% CI 0·92-1·14]; p=0·66), breast cancer mortality (34·4% vs 33·7%; 1·06 [0·95-1·18]; p=0·31), or death from any cause (40·9% vs 41·2%; 1·04 [0·94-1·15]; p=0·45). INTERPRETATION: Tumours downsized by NACT might have higher local recurrence after breast-conserving therapy than might tumours of the same dimensions in women who have not received NACT. Strategies to mitigate the increased local recurrence after breast-conserving therapy in tumours downsized by NACT should be considered-eg, careful tumour localisation, detailed pathological assessment, and appropriate radiotherapy.

Abstract

BACKGROUND: After breast-conserving surgery, radiotherapy reduces recurrence and breast cancer death, but it may do so more for some groups of women than for others. We describe the absolute magnitude of these reductions according to various prognostic and other patient characteristics, and relate the absolute reduction in 15-year risk of breast cancer death to the absolute reduction in 10-year recurrence risk. METHODS: We undertook a meta-analysis of individual patient data for 10,801 women in 17 randomised trials of radiotherapy versus no radiotherapy after breast-conserving surgery, 8337 of whom had pathologically confirmed node-negative (pN0) or node-positive (pN+) disease. FINDINGS: Overall, radiotherapy reduced the 10-year risk of any (ie, locoregional or distant) first recurrence from 35.0% to 19.3% (absolute reduction 15.7%, 95% CI 13.7-17.7, 2p/=20%), intermediate (10-19%), or lower (, link_to_OA_fulltext

Abstract

Aims, results, advantages and possible disadvantages of preoperative chemotherapy (pCHT) for breast cancer are discussed in this review. Established chemotherapeutic regimens are described with respect to new drugs that are added to combinations now and in the future. Illustrating the potential of new components, trastuzumab and cytotoxic chemotherapy, were combined in neoadjuvant trials for the first time. This approach yielded impressing and unprecedented high pathological response rates. An overview regarding current neoadjuvant cytostatic and immunotherapy trials is given.Established prognostic factors like axillary lymph-nodal status are altered during pCHT, which causes the need for new prognostic markers. The consequences of these changes for clinical decision making are demonstrated. It seems possible that the advances of gene array and protein expression profile technologies will lead to improved prognostic and predictive statements. Tumor tissue can be analyzed before during and after treatment in this regard recent studies investigating the response to specific, chemotherapeutics in correlation to molecular markers are reviewed. These approaches might enable us to identify chemoresistance of specific tumors. Furthermore pCHT allows testing of chemosensitivity in vivo in an early stage, which might lead to a more individualized cancer therapy.We discuss radiotherapy after neoadjuvant therapy and the risk of local relapse after breast conserving surgery, which was made feasible by pCHT. It is shown how the evaluation of efficacy of new cancer drugs, using the neoadjuvant situation, can be done more rapidly than in the metastatic and adjuvant setting. Diese Übersichtsarbeit beschäftigt sich mit Zielen, Resultaten, Vorteilen, Kontraindikationen und möglichen Nachteilen der präoperativen Chemotherapie (pCHT) des Mammakarzinoms. Etablierte chemotherapeutische Kombinationen werden mit neuen Pharmaka verglichen, welche momentan und zukünftig in neoadjuvante Regime integriert werden. Das Potential neuerer Komponenten illustrieren erstmals unternommene neoadjuvante Studien, in welchen Trastuzumab und konventionelle Chemotherapeutika kombiniert wurden. Die Raten an pathohistologischen Ansprechraten waren beeindruckend und unerwartet hoch. Ein Überblick über aktuelle präoperative chemotherapeutische und immunotherapeutische klinische Studien wird in dieser Übersichtsarbeit vermittelt. Aufgezeigt werden die therapeutisch bedingten Veränderungen etablierter Prognosefaktoren wie der des axillären Lymphknotenstatus während der pCHT, die sich daraus ergebende Notwendigkeit neue Prognosemarker zu finden und die hieraus erwachsenden Konsequenzen für die klinische Entscheidungsfindung. Es erscheint möglich, dass die Fortschritte der Gene Array und Protein Expressionsprofil Technologie verbesserte prognostische and prädiktive Aussagen ermöglichen. Tumorgewebe kann vor, während und nach der Therapie analysiert werden. Diesbezüglich werden aktuelle Arbeiten, die das Ansprechen der Tumoren auf bestimmte Chemotherapeutika mit molekularen Markern korrelieren, diskutiert. Diese Ansätze könnten uns die frühzeitige Identifikation chemoresistenter Tumoren ermöglichen. Darüber hinaus handelt es sich bei der pCHT um einen in vivo Chemosensitivitätstest, der in Zukunft zu einer individualisierteren und maßgeschneiderteren Krebsbehandlung führen könnte. Wir diskutieren die Strahlentherapie nach neoadjuvanter Therapie und das Risiko eines Lokalrezidivs nach brusterhaltender Chirurgie, welche erst durch die präoperative Applikation der Chemotherapie ermöglicht wurde.Es wird aufgezeigt, wie die Evaluation und Zulassung neuerer Krebstherapeutika im Rahmen von präoperativen Behandlungskonzepten viel schneller als in der metastasierten oder adjuvanten Situation erfolgen kann.

Abstract

Purpose of investigation: The pleiotropic factor Y-box binding protein-1 (YB-1) is clinically correlated with breast cancer patients' poor outcome. Due to the intereference of YB-1 with the estrogen receptor, the authors examined the antiproliferative efficacy of 4-hydroxytamoxifen (4-OHT) and fulvestrant (FUL) in the presence of low and high levels of YB-1. Materials and Methods: The human breast cancer cell line MCF-7 was transfected to overexpress YB-1 protein. 4-OHT and FUL incubation experiments were performed and cell growth behaviour of YB-1 overexpressing MCF-7 cells were compared to unmodified MCF-7 cells expressing endogenous YB-1 levels. Results: The incubation of MCF-7 cells with 100 nM 4-OHT and 1 nM FUL over a period of 120 hours clearly demonstrated the antiproliferative properties of both antiestrogens as expected. Notably, high levels of YB-1 led to an increase of antiproliferative properties in the presence of 4-OHT and FUL. Conclusion: The data presented here demonstrated YB-1 enhances the antiestrogenic efficacy of 4-OHT and FUL. Thus, the group of high level YB-1 mamma carcinoma patients might increasingly benefit from endocrine therapy. [ABSTRACT FROM AUTHOR]

Abstract

Patients with high-risk breast cancer may benefit from dose-escalated chemotherapy. We studied toxicity and therapeutic efficacy of sequential high-dose therapy consisting of two cycles of ifosfamide 12,000 mg/m2, carboplatin 900 mg/m2, and epirubicin 180 mg/m2 (ICE) with peripheral blood stem cell support. Ninety-one patients with advanced breast cancer were included. Fifty-one patients with stage II/III disease and 10 or more tumor-positive axillary lymph nodes received high-dose therapy as adjuvant treatment; the remaining 40 patients were treated for metastatic disease. Peripheral blood stem cells were collected following granulocyte colony-stimulating factor-supported induction chemotherapy. In 68 patients, induction chemotherapy included two cycles of ifosfamide 7,500 mg/m2 and epirubicin 120 mg/m2, while 23 patients received one cycle of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) 135 mg/m2, ifosfamide 6,000 mg/m2, and epirubicin 90 mg/m2. One hundred ninety-two cycles of ICE were supported with a median of 3.5 x 10(6) CD34+ cells/kg body weight (range, 1.7 to 38 x 10(6) CD34+ cells/kg body weight), which resulted in rapid hematologic reconstitution with recovery times, for a median neutrophil count of 0.5 x 10(9)/L of 13 days (range, 6 to 20 days) and for a median platelet count greater than 20 x 10(9)L of 9 days (range, 5 to 24 days). Seven patients received only one cycle of ICE because of progressive disease (in two patients with metastatic disease), central nervous system toxicity (one patient), cardiac toxicity (one patient), severe enterocolitis (one patient), development of human leukocyte antigen antibodies (one patient), and wish to withdraw from the study (one patient). Seventeen patients with metastatic disease received an additional high-dose cycle consisting of the non-cross-resistant agents thiotepa 600 mg/m2, etoposide 1,500 mg/m2, and paclitaxel 165 mg/m2. In patients treated adjuvantly, the probability of disease-free survival was 64% at 47 months, which compares favorably with results of conventional treatment protocols, with a 47% event-free probability at the same time period. The probability of progression-free survival in patients with metastatic disease was 18% at 44 months. In conclusion, sequential high-dose therapy with peripheral blood stem cell support in patients with high-risk breast cancer can be administered safely and offers a potential benefit in the adjuvant setting.

Abstract

Abstract: Osteonecrosis of the jaw (ONJ) is a rare but severe disease which has been diagnosed in women with breast cancer on a bisphosphonate (BP) therapy. Thus, the German society of senology appointed a multidisciplinary task force to establish a consensus on the use of bisphosphonates in breast cancer patients with bone metastases, considering in particular the possible risk of ONJ. This report summarizes the results and recommendations for the prevention and treatment of ONJ in breast cancer patients receiving BP. [Copyright &y& Elsevier]

Abstract

Objective Progesterone influences mammary gland development and probably breast cancer tumorigenesis and functions by regulating a broad spectrum of physiological processes. We investigated receptor membrane-initiated actions of progesterone in MCF-7 breast cancer cells via progesterone receptor membrane component 1 (PGRMC1). Design and method The expression of PGRMC1 in breast cancer was verified by immune fluorescent analysis of paraffin sections. MCF-7 cells were transfected with PGRMC1 (wild type) or PGRMC1 variants. These cells were stimulated with a membrane-impermeable progesterone (P4) conjugate (P4-BSA-fluorescein isothiocyanate, P4-BSA-FITC, 10-6 mol/l) or unconjugated progesterone (P4, 10-6 mol/l) in the presence or absence of the progesterone receptor blocker RU-486 (10-6 mol/l). Additionally, the effects on the expression of vascular endothelial growth factor A (VEGF-A) were determined using quantitative real-time polymerase chain reaction. Results PGRMC1 is perinuclearly localized in breast cancer cells. Western Blot analysis suggests that PGRMC1 is phosphorylated at serine 180. MCF-7-PGRMC1 (S180A) cells show an approximately 35% increase in proliferation after incubation with P4-BSA-FITC compared to MCF-7 control and MCF-7-PGRMC1 (wild type) cells. This effect cannot be blocked by RU-486. P4 reduced proliferation of MCF-7-PGRMC1 cells by approximately 10% compared to untreated controls. P4-BSA-FITC treatment led to a roughly three-fold activation of VEGF-A gene expression compared to MCF-7 cells. Conclusion PGRMC1 is expressed in breast cancer tissue and mediates an RU-486-independent proliferative signal. It might also contribute to VEGF-induced neovascularization in tumor tissue. Thus, screening for PGRMC1 expression might be of interest to identify women with a higher expression of PGRMC1 and who might thus be susceptible for breast cancer development under hormone replacement therapy. H. Neubauer and G. Adam contributed equally to this manuscript. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: In the field of estrogen therapy breast cancer risk is one of the most controversially discussed topic. Actually, the as yet largest placebo-controlled study, the Women''s Health Initiative, rather showed a risk reduction, in contrast to observational studies. In the present study we have investigated the effect of estradiol on TNF-α-induced changes of various markers in human breast cancer cells and compare it with the effect of the antiestrogens tamoxifen and 2-methoxyestradiol. MCF-7 cells were used for the experiments, the incubation time was 96 h. TNF-α elicited a 3–4-fold increase of monocyte-attracting protein-1 (MCP-1) and interleukin-8 (IL-8) as compared to the control value, matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF) were enhanced by 30 to 40%. E2 alone had no effect on MCP-1, slightly reduced the synthesis of MMP-9 and increased VEGF concentrations by about 20%. In combination with TNF, E2 induced a further stimulation of MCP-1, IL-8 and VEGF, whereby the MMP-9 synthesis was not changed. Tamoxifen and the endogenous estradiol metabolite 2-methoxyestradiol seem to be able to partly inhibit the action of TNF-α and estradiol. Our results suggest that estrogens may slightly increase tumor growth and spreading beyond the effect of chemokines such as TNF-α. However, the magnitude of this E2 effect seems to be marginal as compared to the effect of TNF-α alone. The risk of recurrence of breast cancer in patients taking hormone therapy after breast cancer may be slightly enhanced by estrogens, but seems mainly to be driven by the potency of still existing tumor cells to secrete chemokines which can stimulate tumor growth and spreading.

Abstract

Objectives So far, most epidemiological studies investigating breast cancer risk and hormone replacement therapy have been conducted with conjugated equine estrogens (CEE). Recent trials indicate that the addition of progestogens may increase breast cancer risk. In the present study, we compared the effects of the human estrogen 17β-estradiol (E2) with those of the main equine components of CEE, i.e. equilin (Eq) and 17a-dihydroequilin (Dheq) on the proliferation of human breast cancer cells. The proliferative effect of progestogen addition was also investigated. Results All three estrogens increased the proliferation of MCF-7 cells by between 40 and 180%. The most proliferatively potent estrogen was E2, followed by Eq and Dheq, which showed a slightly lower proliferative activity than E2. The addition of progesterone inhibited E2-induced proliferation by about 30%, but only at the high non-physiological concentration of 10 μmol/l. All three progestogens inhibited Eq-induced proliferation, although their effect tended to be low, with values between 5 and 40%. No progestogen reduced Dheq-induced proliferation by more than 20%. In contrast, MPA slightly increased the proliferation rate by about 5% at the high physiological concentration of 0.1 μmol/l when combined with Dheq. The same held true when MPA and NET were added at the high pharmacological concentration of 10 mmol/l, causing increases of about 10%. Conclusions Our results indicate that equine estrogens have a proliferative action similar to that of 17β-estradiol. Continuous addition of progestogens does not result in any major reduction of proliferative potency. Some progestogens may even enhance the estrogen-induced proliferation of pre-existing breast cancer cells, particularly when combined with certain equine estrogens. However, in one of the tested circumstances do progestogens increase the proliferative effect of estradiol, and progesterone has no deleterious effect even at pharmacological levels, in contrast to progestogens.

Abstract

Tibolone is a synthetic progestin with estrogenic and progestogenic properties, used to alleviate menopausal syndromes and for osteoporosis prophylaxis in postmenopausal women. However, only little data are available on tibolone and breast cancer risk and on the effects of tibolone on the cardiovascular system. Therefore, in the present in vitro study, we investigated the effect of tibolone on the growth of the human breast cancer cell line, MCF-7, and on the direct effects of tibolone on the vasculature, i.e. human female coronary endothelial and smooth muscle cells. In the breast cancer cell experiments, tibolone was examined alone and in the presence of 0.1 nM estradiol in the concentration range from 0.001 µM to 1 µM. Tibolone lead to significant cell growth in the concentration range of 0.01 µM to 1 µM and was not able to inhibit estradiol-induced proliferation at the concentrations of 0.01 µM and 0.1 µM. In the vascular endothelial cell culture experiments, tibolone was tested at the concentrations 0.1 µM, 1 µM and 10 µM. Tibolone reduced the synthesis of endothelin as well as the concentrations of E-selectin, PAI-1 and pro-MMP-1. The magnitude of the effects on these markers varied and was in the range of 11%–42%. Concerning smooth muscle cells, tibolone elicited no changes in the proliferation compared to control values. These data suggest that tibolone does have tumour cell-growth promoting effects in vitro. However, tibolone can positively influence the synthesis of markers in cell cultures of human female coronary artery, which modulate vascular tone and which play a decisive role in the various stages of atherosclerosis. Drawing a clinical consequence from our experiments would result in not recommending the use of tibolone in postmenopausal women at high risk for breast cancer development until long-term controlled clinical studies have been performed on the effect of tibolone administration and breast cancer risk. Experimental studies, such as the present one, are useful to explore mechanisms, but clearly cannot replace clinical studies. [ABSTRACT FROM AUTHOR]

Abstract

Purpose: Large-core needle biopsy (LCNB) has become a more widely used technique in the evaluation of breast lesions. This study was undertaken to access the accuracy of percutaneous LCNB on breast lesions and the impact on further proceeding. Methods: A retrospective review of imaging-guided LCNB of 159 breast lesions was done. 143 LCNB were taken with ultrasound guided automated spring gun biopsy and 16 stereotactic-guided with vacuum-assisted biopsy device. Histology and morphobiological parameters were compared with subsequent material from surgery. Results: In 113 core biopsies (71%), an infiltrating breast cancer was diagnosed, 5 biopsies (3%) yielded in-situ/atypical lesions and a benign lesion was shown in 38 cases (24%). In 3 cases, insufficient/necrotic material was obtained. 108 patients underwent subsequent surgery. In 100/108 cases (93%), histology on LCNB and surgery was identical. LCNB was false negative in 5 core biopsies (5%). Immunhistochemical stains of hormone receptors, bcl-2, c-erbB-2, p53 and MIB-1 was comparable on LCNB and on surgical material. Based on the results of LCNB, 17/113 patients (15%) with infiltrating carcinoma were primarily treated with hormones or with neoadjuvant therapy. 32/38 patients (84%) with benign lesions were followed up by imaging control. Conclusions: In patients with benign lesions on imaging, open biopsies can be avoided by LCNB. In patients with biopsy proven carcinoma, therapy planning is improved.The addition of morphobiological parameters allows early individual treatment. [ABSTRACT FROM AUTHOR]

Abstract

Background The presence of disseminated tumor cells (DTCs) in bone marrow of patients with early breast cancer (EBC) has been correlated with increased risk of metastatic disease or locoregional relapse. Zoledronic acid (ZOL) treatment has reduced DTCs in the bone marrow of patients with EBC in several studies. This controlled study sought to confirm these observations. Patients and methods Patients with EBC and DTC-positive bone marrow were randomized (N = 96) to treatment with ZOL plus adjuvant systemic therapy or adjuvant systemic therapy alone. The change in DTC numbers at 12 months versus baseline was measured. Results DTC-positive patients treated with ZOL were more likely to become DTC-negative after 12 months of treatment compared with the controls (67% versus 35%; P = 0.009). At 12 months, DTC counts decreased to a mean of 0.5 ± 0.8 DTCs in the ZOL group and to 0.9 ± 0.8 DTCs in the control group. In addition, ZOL was generally well tolerated. Conclusions Treatment with ZOL improves elimination of DTCs. Further studies are needed to determine whether the reduction in DTCs by ZOL provides clinical benefit. [ABSTRACT FROM PUBLISHER]

Abstract

Abstract: Objective: Since 2003, multiple cases of bisphosphonate-induced osteonecrosis of the jaw (ONJ) were reported. The aim of this study was to describe the incidence and risk factors of ONJ in patients with breast cancer or gynecological malignancies receiving bisphosphonates (BP). Methods: ONJ was recorded for all patients with breast cancer or gynecological malignancies treated with intravenous bisphosphonates at the Department of Gynecology and Obstetrics, University Hospital Tuebingen during April, 1999 and May, 2006. Results: 10 of 345 (2.9%) patients with breast cancer or gynecological malignancies developed ONJ while receiving bisphosphonate therapy. Six patients with ONJ had a history of recent dental procedures. All patients had received zoledronic acid as part of their bisphosphonate regimen. Time of exposure to bisphosphonates and the number of treatment cycles were significant risk factors for the development of ONJ (p <0.001). In patients diagnosed with ONJ the mean number of treatment cycles was 27±18 cycles. However, the mean number of treatment cycles in patients without manifestation of ONJ was 12±12 cycles. Conclusion: Length of exposure to BPs and the cumulative dose of given BPs seem to be the most important risk factors for the development of ONJ followed by dental procedures.

Abstract

Developing primary systemic chemotherapy (PST) regimens that induce higher pathological complete response (pCR) rates remains a challenge in operable breast cancer. We recruited 77 eligible patients into a multicentre phase I/II study to evaluate the maximum tolerated dose (MTD), toxicity and efficacy of preoperative gemcitabine day 1 and 8 (800 mg/m2 fixed dose), epirubicin and docetaxel on day 1 (doses escalated from 60 mg/m2) (GEDoc), repeated 3-weekly for 6 cycles with filgrastim support. MTD for epirubicin was 90 mg/m2 and for docetaxel 75 mg/m2. Dose-limiting toxicities (DLTs) included febrile neutropenia and grade 3 diarrhoea. Clinical response rate was 92%, pCR rate was 26%. 79% of patients had breast-conserving surgery. Grade 3/4 leucopenia was the main toxicity, occurring in 55 (87%) of 63 patients treated at the MTD. Non-haematological toxicity caused no serious clinical problems. In conclusion, GEDoc is highly active as PST. Efficacy and toxicity compare favourably with other effective combinations.

Abstract

The aim of this prospective trial was to evaluate if 3-D ultrasound (US) brings any advantage to breast diagnostics. A total of 65 women with breast lesions (42 malignant, 23 benign) were examined preoperatively with 2-D and 3-D US. The impact of the use of the 3-D coronal plane for the visualization of the infiltrative zone in comparison to 2-D US was evaluated. Additionally, 3-D surface imaging and volumetry were performed. The coronal plane was of benefit when the infiltrative zone was unclear (6 of 8 cases) or not visible (17 of 39 cases; 43.6%) using 2-D imaging. The surface mode was advantageous for imaging complex structures (e.g., a multinodular fibroadenoma). Volumetry yielded a highly significant correlation between 2-D and 3-D US. 3-D US of breast lesions as adjunct to 2-D sonography can offer a better assessment of the infiltrative zone. Moreover, it enables accurate documentation of data. (E-mail: ) [Copyright &y& Elsevier]

Abstract

This prospective, parallel-group, dose-escalation study evaluated the cardiac safety of trastuzumab (Herceptin®) plus epirubicin/cyclophosphamide (EC) in women with human epidermal growth factor receptor-2 (HER2)-positive metastatic breast cancer (MBC) and determined an epirubicin dose for further evaluation. HER2-positive patients received standard-dose trastuzumab plus epirubicin (60 or 90 mg/m2)/cyclophosphamide (600 mg/m2) 3-weekly (EC60+H, n=26; EC90+H, n=25), for four to six cycles; 23 HER2-negative patients received EC alone (90/600 mg/m2) 3-weekly for six cycles (EC90). All patients underwent thorough cardiac evaluation. Two EC90+H-treated patients experienced symptomatic congestive heart failure 4.5 and 6 months after the end of chemotherapy. One EC60+H-treated patient experienced an asymptomatic decrease in left ventricular ejection fraction (LVEF) to <50% 6 months after the end of chemotherapy. No such events occurred in control patients. Asymptomatic LVEF decreases of >10% points were detected in 12 (48%), 14 (56%) and 5 (24%) patients treated with EC60+H, EC90+H, and EC90. Objective response rates with EC60+H and EC90+H were >60%, and 26% for EC90 alone. These results indicate that trastuzumab may be combined with EC with manageable cardiotoxicity and promising efficacy. [Copyright &y& Elsevier]

Abstract

Endocrine therapy is widely accepted for the treatment of hormone receptor-positive breast cancer. However, in many cases eventually resistance will develop and tumor regrows. Combination therapy may be one way to resolve this problem. In the present study we investigated the effect of a combination of the widely used antiestrogen tamoxifen with the endogenous estradiol metabolite 2-methoxyestradiol (2-ME) on the proliferation of human estrogen receptor-positive and receptor-negative breast cancer cells.The receptor-positive cell line MCF-7 and the receptor-negative cell line BM were treated with 4-hydroxytamoxifen (4-OHTam) and 2-methoxyestradiol in the concentration range of 0.8–25 μM alone and equimolar combinations for 4 days. The proliferation of the cells was determined using the ATP-chemosensitivity test.4-Hydroxytamoxifen inhibited proliferation of MCF-7 and BM cells with IC50 values of 31 and 10 μM, the corresponding figures for 2-methoxyestradiol were 52 and 8 μM. The combination showed IC50 values of 6 μM and 4 μM.These results indicate that a combination of tamoxifen with 2-methoxyestradiol showed an additive inhibitory effect concerning the proliferation of estrogen receptor-positive and receptor-negative breast cancer cell lines. Thus a combination of these substances may allow ameliorating of adverse events of tamoxifen by reducing its concentrations and probably also drug resistance and should be tested in clinical trials.
