1.  Side Effects of Standard Adjuvant and Neoadjuvant Chemotherapy Regimens According to Age Groups in Primary Breast Cancer 
Breast Care  2013;8(1):60-66.
Summary
Background
Elderly breast cancer patients are underrepresented in clinical trials and this leads to a lack of knowledge regarding the tolerance and side effects of modern chemotherapy regimens, especially in dose-dense (dd) or dose-intensified combination.
Patients and Methods
In this analysis, data from 4 German, randomized (neo-)adjuvant trials, including anthracycline-based chemotherapy, were evaluated for toxicity, compliance and feasibility. Patients were grouped according to age.
Results
Of the 4,775 patients, 73.6% were < 60 years, 15.8% were 60–64 years and 10.6% were > 64 years. The patients’ compliance decreased with increasing age, the rate of therapy discontinuations was 10.3%; 16.0% were > 64 years old (p < 0.001). The rate of dose reductions also increased with increasing age in the docetaxel/doxorubicin/cyclophosphamide (TAC) (p overall = 0.02) and 5-fluorouracil/epirubicin-cyclophosphamide (FE120C) (p overall < 0.001) treatment groups. Neutropenia grade 3 + 4 in patients of > 64 years was 77% in FE120C- compared to 55% in TAC-treated patients (with primary granulocyte colony-stimulating factors (G-CSFs)). The incidence of febrile neutropenia (FN) was lowest in the regimens without additional taxanes. FN in patients aged > 64 years was lower in the FE120C- than in TAC-and dd-doxorubicin/docetaxel-treated groups.
Conclusion
The range and intensity of toxicity increased with age. Neutropenia did not increase significantly in the dd groups; the highest rate was seen in FE120C-treated patients. FE120C without G-CSFs is not an option in patients older than 64 years.

2.  Toxicity Analysis in the ADEBAR Trial: Sequential Anthracycline-Taxane Therapy Compared with FEC120 for the Adjuvant Treatment of High-Risk Breast Cancer 
Breast Care  2012;7(4):289-295.
Background
Data from meta-analyses have shown taxane-containing therapies to be superior to anthracycline-based treatments for high-risk breast cancer.
Patients and Methods
The ADEBAR trial was a multicenter phase III trial in which patients with lymph node-positive breast cancer were prospectively randomized for either sequential anthracycline-taxane or FEC120 therapy. Patients received 4× epirubicin (90 mg/m2) and cyclophosphamide (600 mg/m2) every 3 weeks (q3w), followed by 4× docetaxel (100 mg/m2) q3w (EC-Doc arm), or 6× epirubicin (60 mg/m2) and 5-fluorouracil (500 mg/m2) on days 1 and 8 and cyclophosphamide (75 mg/m2) on days 1–14, q4w (FEC arm). We compared both arms with respect to toxicity and feasibility.
Results
Hematological toxicity was found significantly more often in the FEC arm. Febrile neutropenia was seen in 11.3% of patients in the FEC arm and in 8.4% of patients in the EC-Doc arm (p = 0.027). Non-hematological side effects of grade 3/4 were rarely seen in either arm. Therapy was terminated due to toxicity in 3.7% of the patients in the EC-Doc arm and in 8.0% of the patients in the FEC arm (p = 0.0009).
Conclusion
The sequential anthracycline-taxane regimen is a well-tolerated and feasible alternative to FEC120 therapy.

3.  Recurrent Mastitis after Core Needle Biopsy: Case Report of an Unusual Complication after Core Needle Biopsy of a Phyllodes Tumor 
Breast Care  2012;7(3):240-244.
Background
In the routine work-up of suspect breast lesions, ultrasound-controlled core needle biopsy (CNB) is the most common tool to acquire tissue for histopathologic analysis in a safe, quick and convenient way. Complications are generally rare. The most common complications are hematoma and infection, each with less than 1 in 1000 cases.
Case Report
Here, we present a case of a 48-year-old patient who underwent CNB for several lesions that were assessed as Breast Imaging Report and Data System (BI-RADS) IV in breast ultrasound and mammography. In the past, she had had 2 bilateral breast reduction surgeries and 1 open biopsy of a fibroadenoma. Histology revealed a phyllodes tumor. Following this, mastitis occurred which was resistant to common conservative measurements such as intravenous antibiotics over months. Finally, mastectomy was performed, followed by adequate wound healing.
Conclusions
In the presented case, the prolonged course of breast infection after CNB was not as expected. If this occurs, conservative treatment with antibiotics can be initiated. Possible additional risk factors such as diabetes mellitus, steroid therapy, or immunosuppression should be identified. However, in case of missing recovery, wide surgical excision is recommended.

4.  ABC1 Consensus Conference – a German Perspective 
Breast Care  2012;7(1):52-59.
A group of German breast cancer experts (medical oncologists and gynaecologists) reviewed and commented on the results of the first international ‘Advanced Breast Cancer First Consensus Conference’ (ABC1) for the diagnosis and treatment of advanced breast cancer. The ABC1 Conference is an initiative of the European School of Oncology (ESO) Metastatic Breast Cancer Task Force in cooperation with the EBCC (European Breast Cancer Conference), ESMO (European Society of Medical Oncology) and the American JNCI (Journal of the National Cancer Institute). The main focus of the ABC1 Conference was metastatic breast cancer (stage IV). The ABC1 consensus is based on the vote of 33 breast cancer experts from different countries and has been specified as a guideline for therapeutic practice by the German expert group. It is the objective of the ABC1 consensus as well as of the German comments to provide an internationally standardized and evidence-based foundation for qualified decision-making in the treatment of metastatic breast cancer.

5.  The German SUCCESS C Study – The First European Lifestyle Study on Breast Cancer 
Breast Care  2010;5(6):395-400.
Summary
Cohort trials have shown evidence that obesity and a low level of physical activity are not only associated with a higher risk of developing breast cancer, but also with an increased risk for recurrence and reduced survival in breast cancer patients. The SUCCESS C study is the first European trial to evaluate the effect of an intensive lifestyle intervention program on disease-free survival in women with early breast cancer and to examine the predictive value of selected biomarker candidates. A total of 3,547 women with early-stage, Her2/neu-negative breast cancer will be included. The first randomization will compare disease-free survival in patients treated with either 3 cycles of FEC (epirubicine, fluorouracil, cyclophosphamide), followed by 3 cycles of docetaxel or 6 cycles of docetaxel-cyclophosphamide, and thus assess the role of anthracycline-free chemotherapy. The second randomization compares disease-free survival in patients with a body mass index of 24–40 kg/m2 receiving either a telephone-based individualized lifestyle intervention program aiming at moderate weight loss or general recommendations for a healthy lifestyle alone. In addition, the study will evaluate the predictive role of cancer-associated and obesity-related biomarkers for the prediction of disease recurrence and survival. This SUCCESS C trial will provide valuable information on the effects of a lifestyle intervention program on the prognosis of early breast cancer patients.

6.  Clinical Recommendations of DEGRO and AGO on Preferred Standard Palliative Radiotherapy of Bone and Cerebral Metastases, Metastatic Spinal Cord Compression, and Leptomeningeal Carcinomatosis in Breast Cancer 
Breast Care  2010;5(6):401-407.
Summary
Background
To provide guidance for clinical practice on preferred standard palliative radiotherapy (RT) of different sites of metastasis for breast cancer patients based on current published evidence complemented by expert opinion.
Methods
The breast cancer expert panel of the German Society for Radiation Oncology (DEGRO) and members of the Working Party of Gynecologic Oncology (AGO) Breast Committee formulated recommendations based on the panel's interpretation of the level of evidence referring to the criteria of evidence-based medicine added to the AGO grades of recommendation.
Results
For different types and sites of metastasis, distinct therapeutic goals (alleviation of symptoms, pain relief, local tumor control, prevention or improvement of neurological deficits, stabilization of the spine or other bones) require complex approaches considering individual factors (i.e. life expectancy, tumor progression at other sites). With regard to different therapeutic goals, different dose concepts and fractionation schedules, and single-versus multi-fraction palliative RT should be adapted individually.
Conclusions
RT is an effective tool in palliation treatment of bone metastasis (BM), cerebral metastasis (CM) and metastatic spinal cord compression (MSCC), or leptomeningeal carcinomatosis (LC) and plays a central role in an interdisciplinary approach. Preferred technique, targeting, and different dose schedules are described in detail in the DEGRO guidelines, which are also integrated in the updated 2010 AGO recommendations.

7.  Zurich Consensus: German Expert Opinion on the St. Gallen Votes on 15 March 2009 (11th International Conference at St. Gallen: Primary Therapy of Early Breast Cancer) 
Breast Care  2009;4(2):109-116.
Summary
A German working group of 23 breast cancer experts discussed the results from the vote at this year's St. Gallen Consensus Conference on Primary Therapy for Early Breast Cancer (March 11–14, 2009) and came up with some concrete recommendations for day-to-day therapeutic decisions in Germany. Due the fact that the concept of the St. Gallen Consensus Conference merely allows for a minimal consensus, the objective of the working group was to provide practice-related recommendations for day-to-day clinical decisions in Germany. One area of emphasis at St. Gallen was tumor biology as a starting point for reaching individual therapeutic decisions. Intensive discussion was necessary with respect to the clinical relevance of predictive and prognostic factors. A new addition to the area of systemic therapy was a first-ever discussion of the adjuvant administration of bisphosponates and the fact that therapy with trastuzumab in HER2 overexpressing breast cancer has been defined as the standard for neoadjuvant therapy. The value of taxanes as a component of (neo)adjuvant chemotherapy as well as the value of aromatase inhibitors for the endocrine adjuvant treatment of postmenopausal patients were affirmed.

8.  Node-positive Breast Cancer: Which Are the Best Chemotherapy Regimens? 
Breast Care  2008;3(4):244-250.
Summary
Breast cancer-associated mortality has been significantly reduced since the 1990s, mainly because of early diagnosis and systemic therapeutic interventions. All three therapy components – cytostatic therapy, endocrine therapy and targeted antibody therapy – are at present necessary tools for the curative treatment of primary breast cancer. This article reviews the evidence base for the use of various chemotherapy schedules in patients with primary, node-positive breast cancer, including schedules in combination with targeted HER2/neu therapy.

10.  Manual of Recommendations for the Diagnosis, Therapy, and Follow-Up of Patients with Breast Cancer of the Tumor Center Munich — a Regional Hands-On Publication 
Breast Care  2008;3(2):100-107.
Summary
The revised 11th edition of the Manual of Recommendations for the Diagnosis, Therapy, and Follow-Up of Patients with Breast Cancer of the publications series of the Tumor Center Munich (Tumorzentrum München, TZM) is an excellent example of a regional hands-on publication which, while based on national and international guidelines, does not replace these. By virtue of countless additions and revisions in the course of 10 editions, the ‘blue tumor manual for breast cancer’ has matured into a hands-on reference work which throughout Germany has found its place on the desks of physicians, and has thus gained a reputation reaching far beyond the TZM. The reputation of this manual is on the one hand founded on the professional competence of the individual authors and project group members. The great strength of the project group, however, surely lies in the broad spectrum of expertise of more than 180 experts of all kinds of specialties, whose continuing interdisciplinary exchange in the course of the present revision has again led to a result which is arousing interest far beyond Munich. This article summarizes some of the TZM project group's own positions on data collection, prevention, adjuvant systemic therapy, and follow-up treatment in an exemplary fashion.
