If you leave the tissue in the 70% for 36 hours, doesn't it cause the tissue to become extra hardened do to the alcohol?

When you have results from an outside lab, i.e. flow results, bone marrows, ect. How do you integrate this into your path report?
It is a verbatim copy inside the report in the same format as the outside lab? Or can it be a copy with the results in a different format? A discussion has occurred within in or transcription department over this matter. We do attach the outside report to the hard copy report in our paper file.

Joyce Weems in Atlanta asks:
>>If TUR is 88307 and resection is 88309, what CPT code do you use for bladder diverticuli?<<
A transurethral resection of the prostate (TURP) is coded 88305 no
matter how many blocks. A TUR of the bladder (presumably a TURBT, that
is, a TUR of a bladder tumor) is 88307. A cystectomy specimen for
cancer (resection) is 88309.
There are no specific instructions for a diverticulum of the urinary
bladder. Diverticula of the GI tract are however coded 88305, and I
would code a urinary tract diverticulum (bladder or urethra) as 88305
also.
The singular is diverticulum, the plural is diverticula. There is no
such word as *diverticuli.
If you don't have a copy of the anatomic pathology CPT codes, 2010
edition, I can send you a PDF of a scan of those pages.

We scan all outside laboratory reports (including consultations, flow
cytometry, special immunohistochemistry, molecular tests, etc) and
insert the scanned material into an addendum which is electronically
tied to the primary report. If the outside report has graphic material
(ie, material that cannot be converted into a "WORD" format) it has to
be excised because at least our vision of Cerner Millenium will not
permit non-text material to be inserted into the report document (We use
an Epson scanner and Epson program that does a very handy job of
converting PDF documents into WORD documents and allows for the excision
of non-WORD material---like fancy headers). When appropriate, ie, it is
not obvious what the results mean, we may add our own comment about how
these results should be interpreted in the setting of our other
material. This saves a lot of transcription (which use to be the way we
accomplished this) and avoids transcriptional errors. It generally
allows capture of the name and address of the outside laboratory, which
is a CLIA requirement. Incorporating the results of special tests into
the report is a CAP requirement.

How much time is the tissue in formalin prior to going in the processor?
Your total time in formalin can not exceed 48 hr. And you will still
need to validate your process if you hold your tissue longer than
"normal processing" time in 70% (ie. more than 1 hr).

Does anyone have any experience with storing formalin fixed
breast
tissue in 70% before processing? I am trying to comply with the
new
guidelines set forth by CAP and ASCO with regard to Her2 and
ER/PR and
since my lab does not operate on the weekend we have been well
above the
48 hour recommended formalin fixation time. Does 70% affect
antigenicity for either Her2 or ER/PR? Any information or

will be greatly appreciated. Thanks :)

How do you define fixation time? A half pound hunk of fat with a tumor in the middle will remain unfixed until blocked. A small biopsy will start fixing almost immediately.

If our cases are needle cores they are almost immediately put into formalin from the patient. That time is recorded by the nurse or the clinician that took the specimen.
The larger breast samples are received fresh from the OR and are immediately grossed either by a PA or resident. Those samples are examined, sliced (to expose the surface area of the specimen) and placed into formalin. That is when the fixation time is recorded for the larger specimens.

How do you define fixation time? A half pound hunk of fat with a tumor in the middle will remain unfixed until blocked. A small biopsy will start fixing almost immediately.

Hi histoworld,
I would like to repeat my staining on the slides already coverslipped but need to remove hematoxilin first.
How to remove hematoxilin? Is it need to repeat Antigen retrieval?
Thanks in advance,

Thanks for your response, Jose, I agree with your points.
I see these guidelines as the first attempt to standardize something that has numerous variables. How can we expect to have the manufacturers of these markers offer (or be required by the FDA) consistent results when our end of this process is "all over the board"?
An ER, PR Her2 that we both buy from the same manufacturer should work the exact same way in my lab as it does in yours, IF we both process in the exact same way.
I doubt very much if histology and IHC testing will ever be as exact as a clinical chemistry assay for example, but it's a start.
I forsee the time gap in formalin shortening as labs get used to this first step.
This would mean more validation, but since we should be doing validation each year, then this may not be such a giant task.

He is looking at online histology programs in the meantime. He does not have a degree in biology/chemistry (it is in literature) but he did work summers in a lab during high school and college and actually did limited histology at that time.

Hi,
I'm going to have to disagree with this approach. Lumping all specimens
into the same procedure (fixation/processing time) is in no way a step
toward individualized care that is so often discussed. Doing this ignores
the basic fundamental differences between the specimens. A liver is
different from a breast and a brain. Likewise a particularly fatty breast is
different from a fiberous one, or one that is cut smaller than the one the
other pathologist (or PA) stuffed into a cassette. Each of these situations
needs to be addressed differently from fixation to processing times and to
be entirely honest staining times in many cases. I fear you may be
oversimplifying the situation and calling it standardization.
All the best,
Amos

OK I usually do not like to chime in on this, but here I go. How can a
true validation of a specific target be obtained if the wiggle room is 6
to 48 hr, or 8 to 72 hr. Where is the precision and accuracy on the
results for this testing if you are going to be varying process for the
weekend vs weekday? This is the flaw in the guidelines in my
perspective, when this much time is allowed it is like anything else.
We are going to go the path of least resistance to change, instead of
what is right. I know that as techs we always want the best, but are
pushed to produce next day. Techs for years have been saying more
fixation is needed on tissue. Well enough of that.
What we do is we hold at 12 hours of fixation for all specimens no
matter what? We document ischemic cold time through our LIS, to include
time placed in formalin, and time of first cut. We feel that all
specimens need the same fixation times. This is imperative to
standardize the process, but once again we also have our processors set
up in such a way that they come off at different times and our
production of H an E is in sync with this. It might sound like a lot,
but we get most of our work done around 96 to 97 % of cases within 24
hours or less using conventional processing techniques.
With the future relying more and more on, patient centered care, through
personalized medicine, we need to really look on how we can do the
optimal requirements, not do the minimal requirements to reach our
goals.

Does anyone out there have an effective policy for monitoring the storage of material at 4C,-20C or -80C. At the moment if any more space is required the solution is usually to buy another fridge or freezer, which then takes up more floor space, uses more electricity and quickly fills as individuals use the space that has become available. So can anyone suggest/ or has in place a system whereby the contents of fridges/freezers can be monitored on a regular basis and old/out of date stuff is disposed off. I expect that all you GLP laboratories have it sorted, and I would welcome any input from you. Ours is a university lab where no such rules/regulations seem to exist and often when people leave they forget to throw out their stuff which can then remain for years.
Many thanks

Here here Amos. This is why I am for using multi tissue controls that have
considered a range for most of the differences in tissues, fixation and
processing encountered.

Hi,
I'm going to have to disagree with this approach. Lumping all specimens
into the same procedure (fixation/processing time) is in no way a step
toward individualized care that is so often discussed. Doing this ignores
the basic fundamental differences between the specimens. A liver is
different from a breast and a brain. Likewise a particularly fatty breast is
different from a fiberous one, or one that is cut smaller than the one the
other pathologist (or PA) stuffed into a cassette. Each of these situations
needs to be addressed differently from fixation to processing times and to
be entirely honest staining times in many cases. I fear you may be
oversimplifying the situation and calling it standardization.
All the best,
Amos

OK I usually do not like to chime in on this, but here I go. How can a
true validation of a specific target be obtained if the wiggle room is 6
to 48 hr, or 8 to 72 hr. Where is the precision and accuracy on the
results for this testing if you are going to be varying process for the
weekend vs weekday? This is the flaw in the guidelines in my
perspective, when this much time is allowed it is like anything else.
We are going to go the path of least resistance to change, instead of
what is right. I know that as techs we always want the best, but are
pushed to produce next day. Techs for years have been saying more
fixation is needed on tissue. Well enough of that.
What we do is we hold at 12 hours of fixation for all specimens no
matter what? We document ischemic cold time through our LIS, to include
time placed in formalin, and time of first cut. We feel that all
specimens need the same fixation times. This is imperative to
standardize the process, but once again we also have our processors set
up in such a way that they come off at different times and our
production of H an E is in sync with this. It might sound like a lot,
but we get most of our work done around 96 to 97 % of cases within 24
hours or less using conventional processing techniques.
With the future relying more and more on, patient centered care, through
personalized medicine, we need to really look on how we can do the
optimal requirements, not do the minimal requirements to reach our
goals.

Hi Richard,
We are a research facility and have the same issue with not always knowing where and whose stuff is in the freezer or refrigerators. Even with the best system though you still have to have people who communicate that they are taking stuff out and also replacing back where it was removed from.
We have instituted the use of a system called Freezer Pro. Here is the web address http://www.ruro.com/products/freezerpro.html
At least this is a start, hope it helps.
Kind Regards!
