Tumor volume in insignificant prostate cancer: increasing threshold gains increasing risk.

Schiffmann J1, Connan J, Salomon G, Boehm K, Beyer B, Schlomm T, Tennstedt P, Sauter G, Karakiewicz PI, Graefen M, Huland H.
The Prostate.Prostate.2015 Jan;75(1):45-9. doi: 10.1002/pros.22889. Epub 2014 Oct 4.
BACKGROUND: An increased tumor volume threshold (<2.5 ml) is suggested to define insignificant prostate cancer (iPCa). We hypothesize that an increasing tumor volume within iPCa patients increases the risk of biochemical recurrence (BCR) after radical prostatectomy (RP).METHODS: We relied on RP

Histoscanning has low sensitivity and specificity for seminal vesicle invasion.

Schiffmann J1, Beyer B2, Fischer J2, Tennstedt P2, Boehm K2, Michl U2, Graefen M2, Salomon G2.
Urology.Urology.2014 Nov;84(5):1168-71. doi: 10.1016/j.urology.2014.06.050. Epub 2014 Oct 24.
OBJECTIVE: To examine the accuracy of HistoScanning (HS) in detecting seminal vesicle (SV) invasion (SVI) within prostate cancer (PCa) patients.METHODS: We relied on our prospective institutional database. Patients who received HS before radical prostatectomy were included in the study cohort. An ex

Simultaneous subependymomas in monozygotic female twins: further evidence for a common genetic or developmental disorder background.

Noell S1, Beschorner R, Bisdas S, Beyer U, Weber RG, Fallier-Becker P, Ritz R.
Journal of neurosurgery.J Neurosurg.2014 Sep;121(3):570-5. doi: 10.3171/2014.2.JNS122179. Epub 2014 Mar 21.
In this paper, a rare case of subependymoma of the fourth ventricle in identical female twins is reported. Magnetic resonance imaging and CT showed nearly identical locations of the tumors in the fourth ventricle and similar growth patterns of the tumors in both sisters. Likewise, postoperative hist
