Welcome
to the Image Cytometry/FISH Diagnostic Laboratory of the Division of Pathology.
Our laboratory is a full service image analysis and fluorescence in-situ
hybridization (FISH) laboratory affiliated with the Division of Pathology
at M. D. Anderson Cancer Center. The image analysis facility was originally
set up for research, but rapidly converted to a clinical service when our
urologists were interested in using it for diagnosis of their clinical
specimens, using a combined cytology-image analysis DNA approach.
We are equipped
with 3 SAMBA image analyzers, one of them with automatic stage which allows
the computer to analyze sample automatically. We are also equipped with
a fully motorized fluorescence microscope, which can be controlled using
the Openlab image acquisition software. The microscope is equipped with
an 8-position filterwheel, with filters for DAPI, spectrum aqua, FITC,
spectrum gold, rhodamine, RG dual band, and RGB triple band viewing. The
stage is motorized in x, y, and z direction, enabling automated through-focus
capturing and slide-scanning. The Openlab software provides deconvolution
(virtual confocal) capabilities, volume rendering, and custom automation
options. Custom macros are available for multi-color 3-dimensional image
acquisition and FISH dot-counting. Addidtional software for custom image
prosessing, analysis and production of publication quality images is also
available. We image about one thousand specimens a year, all cytology specimens,
mostly urologic but also a large number of lymphomas and breast FNAs, as
well as other miscellaneous non-gynecological specimens. We perform about
500 FISH tests for either diagnosis and research of different types of
lymphomas each year. Our lung cancer research project processe 200 paraffin
embedded tissue every year by using a variety of home-made probes.
In addition, we receive about 100 outside wet urological specimens from
community urologists/pathologists for processing for cytology and DNA ploidy/cytology
evaluation.
Our research
is focused on the identification of predictive image analysis feature (PIAF)
in archival histological sections which predict recurrence of lung cancer
or metastatic disease. We also perform fluorescence in-situ hybridization
for different diagnostic or research purposes. The techniques we use include
computerized image analysis, immunohistochemistry staining, and FISH. Our
staff is well trained and is certified individually by either NCA or ASCP.
We also provide,
as a service, a cytology training program for cytotechnologists as well
as a fellowship program for training of Pathologists. Additionally, our
research is based on cytometry image analysis in collaboration with other
departments within M. D. Anderson Cancer Center.
