Treatment and outcomes of patients in the Brain Metastases in Breast Cancer Network Registry.

BACKGROUND: Brain metastases (BMs) have a major impact on life expectancy and quality of life for many breast cancer patients. Knowledge about treatment patterns and outcomes is limited. METHODS: We analysed clinical data of 1712 patients diagnosed with BMs from breast cancer between January 2000 and December 2016 at 80 institutions. RESULTS: Median age at diagnosis of BMs was 56 years (22-90 years). About 47.8% (n = 732) of patients had HER2-positive, 21.4% (n = 328) had triple-negative and 30.8% (n = 471) had hormone receptor (HR)-positive, HER2-negative (luminal-like) primary tumours. The proportion of patients with HER2-positive BMs decreased comparing the years 2000-2009 with 2010-2015 (51%-44%), whereas the percentage of patients with luminal-like tumours increased (28%-34%; p = 0.0331). Patients with BMs in the posterior fossa were more often HER2 positive (n = 169/314, 53.8%) than those diagnosed with triple-negative (n = 65/314, 20.7%) or luminal-like primary breast cancer (n = 80/314, 25.5%), (p < 0.0001). Median overall survival (OS) time after development of BMs for the overall cohort was 7.4 months (95% confidence interval [CI]: 6.7-8.0 months). One-year survival rate was 37.7% (95% CI: 35.2-40.1). Patients with HER2-positive tumours had the longest median OS of 11.6 months (95% CI: 10.0-13.4) compared with 5.9 months (95% CI: 5.0-7.2) for patients with luminal-like and 4.6 months (95% CI: 3.9-5.4) for patients with triple-negative tumours. Patients with HER2-positive tumours who received anti-HER2 treatment had longer median OS than those without (17.1 months versus 7.2 months, p < 0.0001). CONCLUSIONS: Prognosis of patients after developing BMs varies significantly according to the subtype. The outcome in this cohort is similarly poor in triple-negative and HR-positive/HER2-negative patients. Our results underline the high medical need for improvement of treatment and prevention strategies for BMs in breast cancer patients.

[Evaluation of the nationwide DEGUM breast ultrasound training program]. / Evaluation der DEGUM-Mammasonografiekurse nach objektivierbaren Kriterien.

PURPOSE: The aim of this study was to evaluate the quality standard of the nationwide breast ultrasound training program of the German Society of Ultrasound in Medicine (DEGUM) through objective parameters. MATERIALS AND METHODS: 10 quality criteria, based on the recommendations of The National Association of Statutory Health Insurance Physicians (KBV), were defined for this study. All training units of the DEGUM received a questionnaire. The questionnaires and training material were analyzed. RESULTS: All units met the required criteria pertaining to the trainer's qualification, duration per training course and the maximum number of participants per ultrasound machine. Only 1 course did not fulfill the required 50 % practical training time. The requirements to participate in the graduate course (200 self-made and documented cases) were not clearly conceived and a defined training log could be improved. CONCLUSION: DEGUM breast ultrasound training offers trainees a high level of education based on the requirements of the KBV. Despite the high quality of training, the content of course announcements could be improved and an official and structured educational index could be meaningful.

Evaluation of Therapy Management and Patient Compliance in Postmenopausal Patients with Hormone Receptor-positive Breast Cancer Receiving Letrozole Treatment: The EvaluateTM Study.

Introduction: The EvaluateTM study (Evaluation of therapy management and patient compliance in postmenopausal hormone receptor-positive breast cancer patients receiving letrozole treatment) is a prospective, non-interventional study for the assessment of therapy management and compliance in the routine care of postmenopausal women with invasive hormone receptor-positive breast cancer receiving letrozole. The parameters for inclusion in the study are presented and discussed here. Material and Methods: Between January 2008 and December 2009 a total of 5045 patients in 310 study centers were recruited to the EvaluateTM study. Inclusion criteria were hormone receptor-positive breast cancer and adjuvant treatment or metastasis. 373 patients were excluded from the analysis for various reasons. Results: A total of 4420 patients receiving adjuvant treatment and 252 patients with metastasis receiving palliative treatment were included in the study. For 4181 patients receiving adjuvant treatment, treatment with the aromatase inhibitor letrozole commenced immediately after surgery (upfront). Two hundred patients had initially received tamoxifen and started aromatase inhibitor treatment with letrozole at 1-5 years after diagnosis (switch), und 39 patients only commenced letrozole treatment 5-10 years after diagnosis (extended endocrine therapy). Patient and tumor characteristics were within expected ranges, as were comorbidities and concurrent medication. Conclusion: The data from the EvaluateTM study will offer a good overview of therapy management in the routine care of postmenopausal women with hormone receptor-positive breast cancer. Planned analyses will look at therapy compliance and patient satisfaction with how information is conveyed and the contents of the conveyed information.

European experience with a novel noninvasive sensor for intra-amniotic or extra-amniotic evaluation of fetal oxygen saturation.

OBJECTIVE: We evaluated the feasibility of a new instrument for continuous fetal pulse oximetry during labor. The measuring sensor can be placed on the fetal back before or after rupture of membranes. METHODS: One hundred adult women who had completed 32 weeks of gestation and had an anticipated duration of labor greater than 30 minutes were included in the study. Patients with premature rupture of membranes for 24 hours or more, low placental localization, placenta previa or abruption, vaginal bleeding, acute infection, polyhydramnios, oligohydramnios, or uterine or congenital abnormalities were excluded. RESULTS: All sensors were placed successfully. The mean continuous recording time was 276 minutes. Peripheral oxygen saturation as measured by pulse oximeter values were obtained during a median of 64.05% of the recording time. No chorioamnionitis or endometritis was noted. CONCLUSION: The new sensor instrumentation was safe for mother and fetus and was well accepted by parents and physicians.

Topotecan chemotherapy in patients with breast cancer and brain metastases: results of a pilot study.

BACKGROUND: Symptomatic brain metastases occur in approximately 10-15% of patients suffering from breast cancer and are linked to a clear deterioration of the patient's condition. Although radiotherapy is recommended as a primary therapy, the optimal management remains controversial. To evaluate the role of topotecan as a primary chemotherapy for brain metastases, we performed a pilot study in patients with metastatic breast cancer. PATIENTS AND METHODS: 24 patients with newly diagnosed, bidimensionally measurable brain metastases received topotecan, 1.5 mg/m(2) day, 30-min infusion for 5 days every 3 weeks. A total of 93 courses of therapy were administered (range 1-11, median 3 courses per patient). Prior radiotherapy was excluded. Most of the patients had received prior adjuvant or palliative chemotherapy. RESULTS: 3/24 patients were withdrawn from the study for various reasons, 16/24 patients could be evaluated in terms of their response to therapy; 1 and 5 patients showed complete and partial response to therapy, respectively, and 5 patients had a stable condition. The median time of survival was 6.25 months. Hematologic toxicity was the major side effect, nonhematologic side effects occurred rarely and were tolerable. CONCLUSIONS: Our results demonstrate that primary chemotherapy with topotecan is an effective and well-tolerated treatment for patients with breast cancer and CNS metastases. Based on this pilot study, future clinical protocols should be developed including multimodal treatment strategies (i.e. radiotherapy).
