The CHTN mission is to provide prospectively procured biospecimens to scientific investigators with the ability to modify procurement and specimen processing procedures to suit the individual protocol of each investigator. Basic demographic information and clinicopathologic data abstracted from pathology reports are provided to investigators. More detailed clinical annotation may be obtained by arrangement.
Most tissue specimens procured by the CHTN are distributed to investigators as fresh/viable aliquots or snap-frozen. Quality control (QC) for all tissue samples consists of histologic analysis of a paired formalin-fixed paraffin-embedded (FFPE) tissue segment that is examined by a board-certified anatomic pathologist ensuring the delivery of correct tissue type and the elimination of highly necrotic specimens (Fig. A).
For tumor specimens, tumor cellularity, percent stroma and percent necrosis are also recorded (Fig. B). The histologic QC procedures created by the... Read more

The NIH Data Science Special Interest Group is proud to host the webinar Global Perspective on Biobanking and Access to Samples on Friday June 23, 2017 at 10 am EDT. Biobanking leaders from around the world will discuss the challenges and obstacles in sharing and accessing samples and their associated data. The discussion will also address samples that are scarce and how to overcome challenges associated with obtaining these samples. The online audience will be able to send questions directly to the panelists through the GoToWebinar interface. We hope the webinar will facilitate further discussion on these issues and generate new ideas for possible solution and collaboration.Panelists include:
Jonathan Pevsner, Professor, at the Dept. of Neurology, Kennedy Krieger Institute, Dept. of Psychiatry and Behavioral Sciences, Johns Hopkins Medicine. Presentation:... Read more
