Multiple familial trichoepitheliomas (MFT) is an autosomal dominantly inherited disease characterized by multiple skin appendage tumors. We describe a patient showing a continuous spectrum of follicular differentiated neoplasms including classical trichoepitheliomas but also infiltrative growing and finally metastasizing malignant follicular differentiated tumors. Germline mutation analysis revealed a nonsense mutation in the cylindromatosis (CYLD) gene.

Background: In oncology clinical trials, crossover is used frequently but may lead to uncertainties regarding treatment effects.

Objective: To investigate the handling of evidence from crossover trials by the European Medicines Agency (EMA) and the German Federal Joint Committee (G-BA).

Methods: For oncology medicines with early benefit assessments before January 2015, presence of crossover, clinical data, EMA requests for additional data, and G-BA benefit ratings/evidence levels were analyzed from manufacturers' dossiers, G-BA appraisals, European Public Assessment Reports, and original publications.

Background: Previous evaluations of oncological medicines in the German early benefit assessment (EBA) procedure have demonstrated inconsistent acceptance of endpoints by regulatory authorities and the Federal Joint Committee (G-BA). Accepted standard endpoints for regulatory purposes are frequently not considered as patient-relevant in the German EBA system. In this study the acceptance of clinically acknowledged primary endpoints (PEPs) from regulatory trials in EBAs conducted by the G-BA was evaluated across three therapeutic areas.

Therapists and administrative bodies consider a pathological complete remission as an independent and relevant endpoint in evaluations of the clinical utility of neoadjuvant therapy for early breast cancer. The present study aims to investigate which treatment outcomes of a neoadjuvant therapy are considered by the patients themselves to be relevant. With the help of analytic hierarchy process (AHP) methods patient preferences about the treatment targets of neoadjuvant therapy were assessed quantitatively.
