Purpose: To determine the value of a breast ultrasound (US) examination in addition to mammography in cases of American College of Radiology (ACR) tissue pattern III and IV in symptomatic women and women at risk.Materials and Methods: A prospective cohort was initiated between 2001 and 2005 with a total of 59,514 patients and 102,744 mammograms. Documentation was available for 102,557 diagnostic procedures. Breast US was indicated in all women with ACR III and IV in addition to a suspicious clinical examination and in cases of masses and focal asymmetries in mammography.Results: In total, 62,006 additional USs were performed, in which 116 mammographically and clinically occult breast cancers were diagnosed (detection rate: 1.9/1,000 examinations), while mammography alone (40,551 examinations) revealed 903 cancers (22.3/1,000). Of all 1,019 breast cancer findings, 12.8% were detected because of the combination of mammography and US. In the group with ACR III/IV, 15.9% of cancers were found by supplemental US compared with mammography alone.Conclusion: The addition of US to mammography vs. mammography alone resulted in a significant (P < 0.01) increase in breast cancer detection rate.

Background: An increasing proportion of patients are exposed to anthracyclines and/or taxanes in the adjuvant or neoadjuvant setting. Re-exposure in the metastatic stage is limited by drug resistance, thus evaluation of non-cross-resistant regimens is mandatory.Methods: Anthracycline-pretreated patients were randomly assigned to three gemcitabine-based regimens. Chemotherapy consisted of gemcitabine 1.000 mg m(-2) plus vinorelbin 25 mg m(-2) on days 1+8 (GemVin), or plus cisplatin 30 mg m(-2) on days 1+8 (GemCis), or plus capecitabine 650 mg m(-2) b.i.d. orally days 1-14 (GemCap), q3w. The primary end point was response rate.Results: A total of 141 patients were recruited on the trial. The overall response rates were 39.0% (GemVin), 47.7% (GemCis) and 34.7% (GemCap). Median progression-free survival was estimated with 5.7, 6.9 and 8.3 months, respectively. Corresponding median survival times were 17.5 (GemVin), 13.0 (GemCis) and 19.4 months (GemCap). Neutropenia ≥grade 3 occurred in 16.7% (Gem/Vin), 4.4% (GemCis) and 0% (Gem/Cap), whereas non-haematological toxicities were rarely severe except grade 3 hand-foot syndrome in 2.0% of the GemCap patients (per patient analysis).Conclusions: This randomised phase II trial has revealed comparable results for three gemcitabine-based regimens regarding treatment efficacy and toxicity. Gemcitabine-based chemotherapy appears to be a worthwhile treatment option for pretreated patients with metastatic breast cancer. [ABSTRACT FROM AUTHOR]

Problem: As recent studies have suggested abnormalities in the regulation of specific genes in the development of endometriosis, we investigated differentially expressed genes in endometriosis compared to endometrium. Method of study: Gene expression profiles using the Atlas microarray were performed in endometriotic tissue and endometrium. Nine of the 13 genes of endometriotic tissue showed an up-regulation in relation to endometrium and four of the 13 genes a down-regulation. Results: Of the 1176 genes on the Atlas Human 1,2 array, only 13 differentially expressed identical genes were detected after repeating the gene analysis three times. Conclusion: According to our c-DNA analysis some differentially expressed genes may be involved in the pathogenesis of endometriosis. An imbalance in the genes responsible for the reproductive process may lead to a decrease in embryo implantation in patients with endometriosis. [ABSTRACT FROM AUTHOR]

Purpose: The majority of breast cancers are diagnosed at an early stage, and treatment is focused on cure and prolonging disease-free survival. Local therapy (surgery and/or radiation treatment) is standard, along with systemic adjuvant therapy that may effectively prevent or delay relapse and death in early-stage disease. In premenopausal women, adjuvant therapeutic approaches include combination cytotoxic chemotherapy and endocrine therapy. Cyclophosphamide, methotrexate and 5-fluorouracil (CMF) was the established chemotherapy regimen; however, newer regimens have more recently been introduced that may offer some benefit over CMF including anthracycline-containing regimens [e.g. cyclophosphamide, epirubicin and 5-fluorouracil (CEF)], and taxane-containing regimens. For women with oestrogen receptor (ER)-positive disease, a second option is endocrine therapy that aims to suppress mitogenic oestrogen signalling. Until recently, 5 years of tamoxifen was regarded as the standard adjuvant endocrine treatment in ER-positive disease. Ovarian ablation is also effective in premenopausal women, and can be achieved by surgery, radiotherapy, or via the use of a luteinising hormone-releasing hormone analogue such as goserelin. Combining tamoxifen and goserelin treatment provides more effective oestrogen blockade than either drug alone. However, as the third-generation aromatase inhibitors (AIs) have demonstrated improved efficacy over tamoxifen in postmenopausal women with early and advanced disease, combination treatment with goserelin plus an AI may provide optimal oestrogen blockade in premenopausal patients. Conclusions: This review assesses the relative merits of chemotherapeutic and endocrine approaches for the treatment of early breast cancer, and summarises relevant ongoing clinical trials, with an emphasis on the premenopausal setting.

Current standard adjuvant therapies for premenopausal women with early breast cancer include ovarian ablation by surgery or irradiation, chemotherapy and tamoxifen. The value of ovarian ablation in prolonging the survival of premenopausal patients with early breast cancer was clearly established by the analyses performed by the Early Breast Cancer Trialists' Collaborative Group in 1996. More recently, the value of ovarian suppression using the luteinizing hormone releasing hormone analogue goserelin as adjuvant therapy in pre-/perimenopausal women with early breast cancer has been confirmed in a series of studies involving over 8000 patients. The results from these studies provide evidence that goserelin, alone or in combination with tamoxifen, is at least as effective as cytotoxic chemotherapy in patients with hormone receptor-positive tumours and is effective when used after adjuvant chemotherapy. The use of goserelin in the management of early breast cancer presents an option which can avoid the side-effects experienced with cytotoxic chemotherapy and may offer unique benefits to premenopausal patients. The consolidation of these emerging results should help in defining the optimal role for goserelin in pre-/perimenopausal patients with early breast cancer. [ABSTRACT FROM AUTHOR]

This pilot study includes 115 consecutive patients admitted in the period from 1978 to 1981. Patients eligible for this study were at high risk according to the TNM classification with stages pT1-pT3 and pN+, MO. Primary therapy included modified radical mastectomy and axillary-node clearance, one or more ipsilateral nodes being involved in routine histology. All tumors were assayed for estrogen and progesterone receptors. According to the result of the estrogen receptor assay, estrogen-receptor-positive patients were treated with Tamoxifen 30 mg/day for a period of 2 years. Estrogen-receptor-negative patients were treated with cytoxan, methotrexate, and 5-fluorouracil or adriblastin, cytoxan. After a median observation time of 36 months, overall there have been 31 recurrences: 9=17.3% in the estrogen-receptor-positive group and 22=34.9% in the estrogen-receptor-negative group. The analysis of different subgroups showed no significant differences, either in relation to axillary lymph-node status or in relation to menopausal status in the endocrine-treated compared with the polychemotherapy group. This result suggests, especially in the subgroup of patients with involvement of one to three axillary nodes, that estrogen-receptor-positive and estrogen-receptor-negative patients should be considered as separate groups when adjuvant therapy is indicated. Possibly hormone-receptor-positive patients may benefit from endocrine therapy and do not need polychemotherapy. [ABSTRACT FROM AUTHOR]

A sample of 114 primary breast tumors and corresponding constitutional DNA were tested for loss of heterozygosity (LOH) of the YNZ22 and p53 genes, both located in the 17p13 region. Loss of the p53 allele was found in 28 of 44 primary breast carcinomas (64%). In contrast LOH in only 26 of 61 tumors (43%) was detected with the variable number of tandem repeats (VNTR) probe YNZ22 mapping at 17p13.3 close to the p53 locus at 17p13.1. Among 19 tumors informative for both probes allele loss at 17p13.3 never occurred without p53 involvement. These data suggest, that p53 is the target of 17p13 allelic deletions in human breast cancer. Immunohistochemistry showed overexpression of the p53 protein in 25 of 50 cases (50%) presumably reflecting activating point mutations. Overexpression was not correlated with allele loss but seemed to be closely related to the presence of point mutations in this study. No homozygous deletions or rearrangements of the p53 gene were detected. This would argue for an important role of heterozygous p53 mutations in human breast cancer. [ABSTRACT FROM AUTHOR]

Preliminary data of an ongoing phase II-study in metastatic breast cancer patients are presented. Patients with metastatic breast cancer entered the study after hormone therapy had failed; prior treatment with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) was also allowed. The patients were treated with three cycles of 40 mg/m epirubicin i. v. on days 1-3 and 4×120 mg oral verapamil on days 0-3, given every 3-4 weeks. After three chemotherapy courses, ifosfamide was given as a short infusion of 3 g/m on days 1-3. Mesna (20% of the total ifosfamide dose) was given 0, 4 and 8 h after ifosfamide administration. Response was evaluated after three cycles of epirubicin/verapamil and after the last (third) cycle of ifosfamide. The side effects of this treatment were tolerable. The epirubicin/verapamil combination was no more toxic than epirubicin alone. Despite the high dose of verapamil, systolic blood pressure remained above 80 mm Hg, and patients never had a period of strict bed rest. Alopecia was almost complete after induction therapy with epirubicin/verapamil, and nausea and vomiting were absent or mild during epirubicin/verapamil chemotherapy and were easily controlled by antiemetics during ifosfamide treatment. Stomatitis and mucositis, the main toxic effects, could be ameliorated by intensive mouth-washing procedures. The haematological toxicity was greater after epirubicin/verapamil treatment than after ifosfamide therapy, but neither bleeding nor infections due to thrombocytopenia or leucopenia were observed.
