Expression of NRG1 and its receptors in human bladder cancer

BACKGROUND: Therapies targeting ERBB2 have shown success in the clinic. However, response is not determined solely by expression of ERBB2. Levels of ERBB3, its preferred heterodimerisation partner and ERBB ligands may also have a role. METHODS: We measured NRG1 expression by real-time quantitative RT–PCR and ERBB receptors by western blotting and immunohistochemistry in bladder tumours and cell lines. RESULTS: NRG1a and NRG1b showed significant coordinate expression. NRG1b was upregulated in 78 % of cell lines. In tumours, there was a greater range of expression with a trend towards increased NRG1a with higher stage and grade. Increased expression o

ESUR prostate MR guidelines 2012

The aim was to develop clinical guidelines for multi-parametric MRI of the prostate by a group of prostate MRI experts from the European Society of Urogenital Radiology (ESUR), based on literature evidence and consensus expert opinion. True evidence-based guidelines could not be formulated, but a compromise, reflected by “minimal” and “optimal” requirements has been made. The scope of these ESUR guidelines is to promulgate high quality MRI in acquisition and evaluation with the correct indications for prostate cancer across the whole of Europe and eventually outside Europe. The guidelines for the optimal technique and three protocols for “detection”, “staging” and “node and bone” are presented. The use of endorectal coil vs. pelvic phased array coil and 1.5 vs. 3 T is discussed. Clinical indications and a PI-RADS classification for structured reporting are presented
