Background. Currently the choice of breast cancer therapy is based on prognostic factors. The proliferation marker Ki-67 is used increasingly to determine the method of therapy. The current study analyses the predictive value of Ki-67 in foreseeing breast cancer patients' responses to neoadjuvant chemotherapy. Methods. This study includes patients with invasive breast cancer treated between 2008 and 2013. The clinical response was assessed by correlating Ki-67 to histological examination, mammography, and ultrasonography findings. Results. The average Ki-67 value in our patients collectively (n = 77) is 34.9 ± 24.6%. The average Ki-67 value is the highest with 37.4 ± 24.0% in patients with a pCR. The Ki-67 values do not differ significantly among the 3 groups: pCR versus partial pathological response versus stable disease/progress (P = 0.896). However, Ki-67 values of patients with luminal, Her2 enriched, and basal-like cancers differed significantly from each other. Furthermore, within the group of luminal tumors Ki-67 values of patients with versus without pCR also differed significantly. Conclusion. Our data shows that the Ki-67 value predicts the response to neoadjuvant chemotherapy as a function of the molecular subtype, reflecting the daily routine concerning Ki-67 and its impressing potential and limitation as a predictive marker for neoadjuvant chemotherapy response. © 2014 Juhasz-Böss Ingolf et al.

Purpose: Teaching ultrasound procedures to undergraduates has recently been proposed to improve the quality of medical education. We address the impact of applying standardized ultrasound teaching to our undergraduates. Methods: Medical students received an additional theoretical and practical course involving hands-on ultrasound screening during their mandatory practical training week in obstetrics and gynecology. The students’ theoretical knowledge and fetal image recognition skills were tested before and after the course. After the course, the students were asked to answer a course evaluation questionnaire. To standardize the teaching procedure, we used Peyton’s 4-Step Approach to teach the skills needed for a German Society of Ultrasound in Medicine Level 1 ultrasound examiner. Results: The multiple-choice question scores after the course showed statistically significant improvement (50 vs. 80 %; P < 0.001). The questionnaire revealed that students were satisfied with the course, felt that it increased their ultrasound knowledge, and indicated that they wanted more sonographic hands-on training in both obstetrics and gynecology and other medical fields. Conclusion: Using practical, hands-on medical teaching is an emerging method for undergraduate education that should be further evaluated, standardized, and developed. © 2016 Springer-Verlag Berlin Heidelberg Source
