Abstract: INTRODUCTION: The goal of the 2008 updated guideline: early detection of breast cancer in Germany is to support physicians as well as healthy and affected women in the decision-making process involved in the diagnostic chain for the early detection of breast cancer by providing them with evidence- and consensus-based recommendations. The updated guideline replaces the guideline issued in 2003. MATERIALS AND METHODS: The guideline forms the basis for developing an effective and efficient national early breast cancer detection program that meets the standards set by the Council of Europe and WHO for cancer control programs. The guideline presents the current, evidence- and consensus-based state of scientific knowledge in a multidisciplinary approach for the entire diagnostic chain, consisting of history taking and risk consultation, information on health behavior, clinical breast examination, diagnostic imaging, image-guided percutaneous tissue-acquisition techniques, open surgical excisional biopsy and pathomorphological tissue evaluation. The guideline recommends a set of quality indicators to assure resource availability, performance quality and outcomes enhancing total quality management for early breast cancer diagnosis. CONCLUSION: Currently, early detection of breast cancer offers the most promising possibility to optimize the diagnosis and treatment of breast cancer and, as a result, reduce breast cancer mortality and improve health related quality of life in women.

Abstract: A system for quality-of-life diagnosis and therapy (QoL system) was implemented for breast cancer patients. The system fulfilled the criteria for complex interventions (Medical Research Council). Following theory and modeling, this study contains the exploratory trial as a next step before the randomised clinical trial (RCT) answering three questions: (1) Are there differences between implementation sample and general population? (2) Which amount and type of disagreement exist between patient and coordinating practitioners (CPs) in assessed global QoL? (3) Are there empirical reasons for a cutoff of 50 points discriminating between healthy and diseased QoL? Implementation was successful: 74% of CPs worked along the care pathway. However, CPs showed preferences for selecting patients with lower age and UICC prognostic staging. Patients and CPs disagreed considerably in values of global QoL, despite education in QoL assessment by outreach visits, opinion leaders and CME: Zero values of QoL were only expressed by patients. Finally, the cutoff of 50 points was supported by the relationship between QoL in single items and global QoL: no patients with values above 50 dropped global QoL below 50, but values below 50 and especially at 0 points in single items, induced a dramatic fall of global QoL down to below 50. The exploratory trial was important for defining the complex intervention in the definitive RCT: control for age and prognostic stage grading, support for a QoL unit combining patient's and CP's assessment of QoL and support for the 50-point cutoff criterion between healthy and diseased QoL.

Abstract: BACKGROUND AND AIMS: A system for quality of life (QoL) diagnosis and therapy in breast cancer patients was developed according to the Medical Research Council (MRC) framework of complex interventions. Along MRC's five phases in the continuum of evidence, the present paper deals with phase I: modeling (i.e., delineating the conceptual, methodological, and logistic requirements). BASIC ELEMENTS: Theoretical background is a new conceptualization of QoL that provides a rational basis to diagnose "diseased" QoL. A care pathway as the central part of modeling is composed of the following interrelated structural elements: patients (n = 170), clinicians (n = 10), experts in a quality of life unit (n = 5), coordinating practitioners (n = 38), local opinion leaders (n = 12), and professional therapists for QoL enhancing therapies (n = 75). Networking of these structural elements was achieved by clinical algorithm. In the clinical center, the patient and doctor delivered a questionnaire (EORTC) and health status report. The QoL unit transformed it into a profile and experts' report. The coordinating practitioner transformed the latter into a decision on QoL therapy and the care pathway ended with the professional therapists. Implementation of this system used a multifaceted strategy including educational outreach visits, local opinion leaders, and quality circles. CONCLUSION: The suffering cancer patient is the main focus of this QoL diagnosis and therapy system. It will have to pass the rigorous test of a definitive randomized trial.

Abstract: BACKGROUND: The project conducted at the Tumour Centre in Regensburg aims to integrate quality of life (QL) diagnostics with the therapy of breast cancer patients and to evaluate the efficacy of QL diagnostics in the context of a randomized clinical trial. METHODS: The Regensburg Tumour Centre provides the infrastructure of the present project (telemedicine, project groups, quality circle). The treatment of breast cancer patients is based on the recent national breast cancer therapy guideline, including assorted QL-enhancing therapy options such as pain therapy, physiotherapy and lymphatic drainage, psychotherapy, social counselling and rehabilitation, nutrition and sports. During an implementation phase a new method of QL diagnostics has been developed. Five experts with varying professional background use the individual patient's QL profile and clinical and socio-demographic information in order to generate a QL report including a treatment recommendation. The study is designed as a two- arm randomized clinical trial with one test group (communication of the QL findings to the co-ordinating physician) and a control group (no communication). Patients with newly diagnosed breast cancer who are treated in the study region by one of the co-ordinating doctors will be included in this randomized study. At designated points in time QL assessments (EORTC QLQ-C30 plus BR23) will be conducted over a 12-months period. EXPECTED RESULTS: We expect that patients in the test group will experience a lower amount of QL deficits at the end of the study period (M = 1, SD = 2) than patients in the control group (M = 2, SD = 2). The statistical confirmation of this expected effect requires a total sample size of N = 200 (n = 100 vs. n = 100, alpha = 5% [two-tailed], beta = 10%). CONCLUSIONS: This is the first study to evaluate a new form of QL diagnostics in the complexity of a real patient care environment, and it promises to make the inclusion of the quality of life concept into the current breast cancer treatment guideline more tangible.

Abstract: OBJECTIVES: Improvements in the life expectancy of women with breast cancer raise important questions how to improve quality of life (QoL) for women sustaining complications and side effects of cancer treatment. The presented study examined the prevalence of arm morbidity in a cohort of primary breast cancer patients over time as a result of the extent of axillary lymph node dissection. Of particular interest is the question of using a recognized QoL assessment instrument at defined assessment points as an endpoint criteria of oncological treatment. METHODS: A prospective, population-based, longitudinal cohort study of patients with primary breast cancer was performed (n = 389). QoL data (EORTC QLQ C30 + BR23) and clinical data were assessed at designated time points. Primary endpoint of this analysis was patient reported arm morbidity assessed with the three-idem scale in the BR 23 (swelling, moving, pain). RESULTS: 20% of the patients evidenced considerable impairments in arm functioning. Arm morbidity was significantly related to the number of lymph nodes dissected (P < 0.002 entire cohort, P < 0.001 lymph node negatives) and was independent of age, stage of the disease, kind of breast surgery and radiation treatment. Early impairments in arm functioning (below 50 score values) assessed within 6 months after axillary surgery was a good predictor for late arm morbidity at 12 months RR 11.5 (CI 95% 4.7-28.4), 24 months RR 6.0 (CI95% 2.8-13.3) and 36 months RR 3.8 (CI 95% 1.8-7.9). CONCLUSIONS: Arm morbidity after axillary surgery is a severe and chronic condition affecting many breast cancer patients. The recognized QoL assessment instrument depict patients with severe impairments in arm functioning after axillary lymph node dissection and predict late arm morbidity. To increase patients' quality of life it thus may serve as a valid assessment tool for screening, allowing early referral for treatment and monitoring.

Abstract: The aim of this evidence-, consensus- and outcome-based good clinical practice guideline is to help physicians, and women in making appropriate healthcare decisions about the early detection of breast cancer. The principle of early detection of breast cancer comprises the detection and diagnosis of pre-malignant breast tumours (UICC stage 0, carcinoma in situ) with a possible cancer risk reduction and the detection and diagnosis of breast cancer at an early stage (UICC stage 1) with a scientifically proven 90% chance of cure. By establishing a nation-wide comprehensive quality assurance program for the early detection of breast cancer this guideline lays the foundation for a timely reduction of breast cancer mortality and achievement of cure with less impairment of patient's quality of life. It would appear that this guideline makes major improvements in women's healthcare feasible.

Abstract: Systematically developed, evidence- and consensus-based guidelines are important tools for improving health care services. The effectiveness of a guideline does not only relate to its methodological quality but also to the implementation strategy used. The following paper describes the systematic development of a strategy for implementing and evaluating the guideline "Early Detection of Breast Cancer in Germany" as part of a national project. A multi-faceted systematic implementation strategy has been developed addressing existing barriers and building on projects that have recently been introduced in Germany to improve the early detection and management of breast cancer. The aim is to induce behavioural changes in women as healthcare recipients and physicians as healthcare providers, both involved in the medical decision-making process within the scope of the guideline. Furthermore, it supports organisational changes to assure compliance with the guideline by means of quality assurance and quality management. To ensure evaluation of the implementation process a set of quality indicators have been identified for the baseline assessment of structures, provider performance and outcomes. Both the effectiveness of the implementation process and the effectiveness of the guideline itself will be measured by using the same set of indicators for reevaluation within a pre-defined time interval of 18 months. The quasi-experimental design of this uncontrolled before and after implementation study outlined in the present paper allows the assessment of clinically relevant changes using quality indicators that measure the effectiveness of the guideline on a national level.

Abstract: OBJECTIVE: Quality of life (QoL) is increasingly considered as an important endpoint in clinical studies but difficult to use in clinical practice. For daily clinical practice, we developed a computer program that is able to calculate and draw QoL profiles for individual cancer patients. METHODS: The computer program was developed in several steps during the course of studies with different patient populations (prospective cohort study, randomised surgical trial, breast cancer patients, all tumour patients of a clinic) and using different software packages. RESULTS: The current version is based on Microsoft ACCESS and combines QoL data and medical data. Automated QoL profile output comprises 10 scores that are of clinical relevance. Scores range from 0 (worst) to 100 (best), with 50 considered as the threshold for intervention. CONCLUSIONS: Practitioners found QoL-profiles comprehensible and clinically useful. QoL profiles are the crucial link between the QoL concept and QoL enhancing treatment decisions.

Abstract: BACKGROUND: The present analysis focuses on the long term psychological reactions to early stage breast cancer. Two hypotheses were formulated. The first hypothesis draws a direct link between tumour size/survival chances and Quality of life (QoL): The better the survival chances, the better QoL ('biological danger model'). The second hypothesis assumes that localized early breast cancer has excellent prognosis (> 90% five year survival rate), and that therefore QoL differences between various forms of early breast cancer should be minimal ('medico-pragmatic model'). PATIENTS AND METHODS: In a defined rural area with 252.000 inhabitants (small-area-analysis), a total of n = 389 patients with primary breast cancer were recruited. For the present analysis we selected a subgroup (n = 269) from the cohort by tumour size (pTis, pT1a,b, pT1c, and pT2). QoL scores for global quality of life, emotional functioning and future perspective were computed according to the EORTC manual and compared to age-matched norm data of the German population. RESULTS: A total of 690 QoL questionnaires were obtained from n = 269 patients with comparable completion rates within the four subgroups (pTis, pT1a,b, pT1c, and pT2).For all four groups and in all scores there were improvements over time. Generally, pTis always scored highest, pT2 always lowest, the other two groups in between.After one year pTis patients had higher mean scores in global quality of life than the norm. In contrast, pT1a,b were considerably lower than the norm and the difference between these two was 17.2 score points. It seems that the small difference (3.5%) in five year survival chances between pTis and T1 a,b tumours transforms into marked differences regarding quality of life, thus supporting a biological danger model of the survival/QoL relationship. CONCLUSIONS: Our results show that physicians have to realise although their early breast cancer patients have excellent survival chances, psychological distress is present. From a clinical perspective we would recommend that early stage breast cancer patients, and especially patients with occult, pT1a,b tumours be informed about their excellent prognosis. In addition, cognitive therapy might help patients stop worrying about their cancer.

Abstract: Implementation is the stepwise introduction of a concept with the goal to change the behaviour of health care providers. The concept of quality of life (QL) was implemented in order to improve the regional care for cancer patients. The following steps were taken: creating a quality circle, teaching the concept QL, listing QL-enhancing therapy options, graphically presenting individual patients in the form of QL-profiles. In the course of an implementation study QL-profiles of individual patients were sent to their respective practitioners. Doctors judged these profiles as comprehensible (100%) and informative (55%). QL-profiles influenced doctor-patient communication (42%), but had no impact on therapeutic decisions (0%). Acceptance of QL-profiles was higher in doctors treating breast cancer patients (67% response rate) than in doctors treating rectal cancer patients (25%). Reasons for this difference as well as driving and restraining forces for implementing the QL-concept were analysed through a barrier analysis.

Abstract: BACKGROUND AND OBJECTIVES: Breast-conserving surgery requires excision of all gross tumor and subsequent radiation therapy. It is generally accepted that the presence of microscopically positive margins requires reexcision. The goal of this study was to identify characteristics that distinguish breast biopsy specimens with positive margins that when reexcised are free from residual tumor. This population of patients may benefit from breast irradiation only, without the need for another surgical procedure. METHODS: One hundred and fifteen of 395 cancer-proven biopsies had positive surgical margins and were treated with reexcision or mastectomy. Sixty-seven of these were negative for residual tumor and 48 were positive for residual tumor. Evaluation for tumor type, tumor size, grade, presence of vascular invasion, volume of the biopsy specimen, true positivity and the number of positive margins, multifocality of the tumor, and type of anesthesia was done by univariate and multivariate analysis. RESULTS: Univariate and multivariate analysis revealed that factors associated with a positive reexcision included margin status, method of detection, histologic appearance, and type of anesthesia used. CONCLUSION: These results suggest that small, clinically detectable unifocal tumors could be treated without the need for a further excision. Eradication of microscopic residual tumor could be done by irradiation only, sparing the patient an additional surgical procedure.
