I have worked with whole slide scanners and digital image analysis since 1998. We currently own scanners from 3 different vendors. Also, I have participated in whole slide scanner marketing research, sitting at a discussion table with a dozen people from different hospitals.
My experience has been that most departments purchase scanners without a clear need. For example, some want to scan and archive slides, to make them available for review. That makes some sense in theory. However, in every institution I've talked to, they end up paying for the scanner, a tech to do the work, the service contract and the server space to store the images, which can be huge, up to 20 *giga*bytes per *slide... then find that it is rare for anyone to ever actually look at the scanned images. Most pathologists find it is more expedient to simply pull the glass slides out of the archive. In New York, we are required by law to archive glass slides for at least 10 years anyway. So, my advice, for what it's worth, is not to purchase any whole slide scanner unless you have a clear and well defined need (we have 3 giant systems, rarely used, taking up space and gathering dust). For example, if you need to store images from consultation slides before returning them to another institution, why not just snap a few photomicrographs? Being able to view a couple of small, representative pictures is better than having to wade through an entire scanned slide. ------------------------------------------------------------------------------- Scott Ely, MD MPH Associate Director, Hematopathology Fellowship Program Section of Hematopathology Department of Pathology Weill Medical College of Cornell University New York Presbyterian Hospital Room: Starr 715 525 E. 68th Street New York, NY 10065 PH: 212-746-2442 FAX: 212-746-2009 http://www.cornellphysicians.com/scottely/ Legal Confidentiality Notice: This e-mail message, including any attachments, is for the sole use of the original intended recipient(s) selected by Dr. Ely and may contain confidential and privileged information.

Keith Kaplans site also has a lot of information - http://tissuepathology.com/ There are other scanners that I would considers - Phillips, Hamamatsu, etc. you should look at those too. I know that Hamamatsu also scans fluorescent but not sure about Phillips or Ventana. Leica scanners use Slide Path for their database, I'm not sure what the others use for their database. We have an Aperio ScanScope XT but it only scans brightfield. Some companies that sell scanners also have analysis tool boxes and databases that you can purchase with the scanner and some companies only sell the scanner and you will have to figure out what you are going to do for your database, storage and analysis. If you are looking at analysis and if you are in the clinical setting I would definitely pick a company that has had some of their software 510K cleared for specific analysis (ER/PR, Her2, etc) that will help your internal validation process.

We are looking for labs who can help us test the effectiveness of this process. If you are having difficulty getting good IHC or ISH results from 10+ or even 20+ year old specimens, let me know, and we will gladly treat some of your slides for free, if you will share the resulting images with us. We posted this request here once before, and we did get some interest, but we are still not convinced that we have adequate independent verification.

This is how we deal with dry chemicals and stains. A lot of times they do not come with an expiration date. If no expiration date/retest date is listed we give them an expiration date/retest date of 5 years post receipt. After that date we place them in a special area that is marked - Past Retest Date - Do not use until retested. We have a reagent control SOP that explains all of this. I'm not familiar with the "Good until used" designation. For retest we just run a special stain that contains a solution prepared from the chemical and if it stains appropriately we give that chemical a new expiration/retest date and just make sure we document the process appropriately. We just initiated this SOP recently so have not yet had to perform any retests. We update our chemical inventory as new chemicals are ordered, but once a year we review and check all our chemicals for inventory and that we have updated MSDS's available. I can send a pdf of our reagent control SOP if you would like it. If you are striving to be a GLP compliant lab and are heading to NSH convention this year I'll be giving a workshop on GLP compliance in the histology lab with our Facility Quality Assurance Manager.

They're dated 'Good until used'. ? Would someone elaborate on how we came to have outdates on things that never had them before, and how those outdates are determined? ? Is there a procedure or policy you might share so we can keep our old but good items in service until we run out rather than in 12 months (EEEK!!!) ? Many thanks! ?

The reason is first that less fixation does not preserve the tissue and antigens as well (more extraction of proteins in the processing steps), and second, antigen retrieval of any type is more damaging to under-fixed tissue. Studies have shown that 6 hours is a minimum to achieve formalin cross-linking of peptides and inactivate enzymes. After that time period antigen retrieval will be reproducible. Longer fixation is ok. Many studies have shown good antigen retrieval for the vast majority of antigens even after months of fixation when buffer-based heat antigen retrieval is used (as opposed to enzyme digestion). An optimum time is probably in the neighborhood of 16 to 24 hours. But most labs don't do that (clinical labs) and usually 6-12 hours fixation is used. Her2 and ER/PR guidelines specify minimum 6 hours fixation for bx cores and trimmed tissue.
