Praxisnahe und effiziente ERP-Ausbildung im studentischen Projekt PROBAS
Mit dieser Arbeit werden Möglichkeiten aufgezeigt, eine universitäre Lehrveranstaltung so zu gestalten, dass sie einen hohen didaktischen, fachlichen und praktischen Anspruch erhält und den teilnehmenden Studenten mehr als nur ERP-spezifisches Fachwissen vermittelt. Um diesem Anspruch gerecht zu werden, wird die Lehrveranstaltung PROBAS an der TU Ilmenau als die universitäre Lehre ergänzendes SAP-Projekt organisiert. Der Beitrag zeigt auf, wie diese ERP-Ausbildung effizient aufgebaut, gemanagt und das Projektmanagement laufend verbessert wird, um kommenden Herausforderungen in der WI-Lehre zu begegnen. Es werden innovative Lehrkonzepte und fachliche Lehrinhalte an erfolgreichen, praktischen Beispielen vorgestellt, die sich im Zusammenhang mit einer universitären Ausbildung im ERP-Bereich über Jahre bewährt haben
Potential of Lesion-to-Fat Elasticity Ratio Measured by Shear Wave Elastography to Reduce Benign Biopsies in BI-RADS 4 Breast Lesions
Objectives—We evaluated whether lesion-to-fat ratio measured by shear wave
elastography in patients with Breast Imaging Reporting and Data System (BIRADS)
3 or 4 lesions has the potential to further refine the assessment of Bmode
ultrasound alone in breast cancer diagnostics.
Methods—This was a secondary analysis of an international diagnostic multicenter
trial (NCT02638935). Data from 1288 women with breast lesions categorized
as BI-RADS 3 and 4a–c by conventional B-mode ultrasound were
analyzed, whereby the focus was placed on differentiating lesions categorized as
BI-RADS 3 and BI-RADS 4a. All women underwent shear wave elastography
and histopathologic evaluation functioning as reference standard. Reduction of
benign biopsies as well as the number of missed malignancies after
reclassification using lesion-to-fat ratio measured by shear wave elastography
were evaluated.
Results—Breast cancer was diagnosed in 368 (28.6%) of 1288 lesions. The
assessment with conventional B-mode ultrasound resulted in 53.8% (495 of
1288) pathologically benign lesions categorized as BI-RADS 4 and therefore
false positives as well as in 1.39% (6 of 431) undetected malignancies categorized
as BI-RADS 3. Additional lesion-to-fat ratio in BI-RADS 4a lesions with a
cutoff value of 1.85 resulted in 30.11% biopsies of benign lesions which correspond
to a reduction of 44.04% of false positives.
Conclusions—Adding lesion-to-fat ratio measured by shear wave elastography to
conventional B-mode ultrasound in BI-RADS 4a breast lesions could help reduce
the number of benign biopsies by 44.04%. At the same time, however, 1.98% of
malignancies were missed, which would still be in line with American College of
Radiology BI-RADS 3 definition of <2% of undetected malignancies
Multicenter Prospective Cohort Study of the Patient-Reported Outcome Measures PRO-CTCAE and CAT EORTC QLQ-C30 in Major Abdominal Cancer Surgery (PATRONUS): A Student-Initiated German Medical Audit (SIGMA) Study
Background!#!The patient-reported outcomes (PRO) version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) and the computerized adaptive testing (CAT) version of the EORTC quality-of-life questionnaire QLQ-C30 have been proposed as new PRO measures in oncology; however, their implementation in patients undergoing cancer surgery has not yet been evaluated.!##!Methods!#!Patients undergoing elective abdominal cancer surgery were enrolled in a prospective multicenter study, and postoperative complications were recorded according to the Dindo-Clavien classification. Patients reported PRO data using the CAT EORTC QLQ-C30 and the PRO-CTCAE to measure 12 core cancer symptoms. Patients were followed-up for 6 months postoperatively. The study was carried out by medical students of the CHIR-Net SIGMA study network.!##!Results!#!Data of 303 patients were obtained and analyzed across 15 sites. PRO-CTCAE symptoms 'poor appetite', 'fatigue', 'exhaustion' and 'sleeping problems' increased after surgery and climaxed 10-30 days postoperatively. At 3-6 months postoperatively, no PRO-CTCAE symptom differed significantly to baseline. Patients reported higher 'social functioning' (p = 0.021) and overall quality-of-life scores (p &lt; 0.05) 6 months after cancer surgery compared with the baseline level. There was a lack of correlation between postoperative complications or death and any of the PRO items evaluated. Feasibility endpoints for student-led research were met.!##!Conclusion!#!The two novel PRO questionnaires were successfully applied in surgical oncology. Postoperative complications do not affect health-reported quality-of-life or common cancer symptoms following major cancer surgery. The feasibility of student-led multicenter clinical research was demonstrated, but might be enhanced by improved student training
