Glossary (1/2)

        Term                               What We Mean
----------------------  --------------------------------------------------------
Primary Staining        To see the tissue under a microscope, the sections are
                        stained with one or more pigments. This is done to give
                        contrast to the tissue being examined, as without
                        staining it is very difficult to see differences in cell
                        morphology. Hematoxylin and eosin (H&E) are the most
                        commonly used stains in histology and histopathology
--------------------------------------------------------------------------------
Immunohistochemistry    IHC refers to the process of localising proteins in
(IHC)                   cells of a tissue section exploiting the principle of
                        antibodies binding specifically to antigens in
                        biological tissues. Immunohistochemical staining is
                        widely used in the diagnosis of cancer. Specific
                        molecular markers are characteristic of particular
                        cancer types
--------------------------------------------------------------------------------
In Situ Hybridisation   ISH is a type of hybridisation that uses a labelled
(ISH)                   complementary DNA or RNA strand (i.e., probe) to
                        localise a specific DNA or RNA sequence in a portion or
                        section of tissue (in situ). DNA ISH can be used to
                        determine the structure of chromosomes
--------------------------------------------------------------------------------
FISH                    Is a specific form of ISH using fluorescent probes which
                        bind only to those parts of the chromosome with which
                        they show a high degree of sequence similarity
--------------------------------------------------------------------------------
CISH                    Chromogenic ISH is a lower cost alternative to FISH, as
                        it uses conventional enzyme (peroxidase) reactions to
                        detect the probes that bind to the target sequence.
                        Because this technique does not require a fluorescent
                        microscope to analyze the binding pattern, it is easier
                        to perform and lower cost
--------------------------------------------------------------------------------

Stratifying Marker      A biomarker used to differentiate patient populations
                        according to drug response
--------------------------------------------------------------------------------
Prognostic Marker       A biomarker used to predict survival i.e. in tumor
                        staging, where the degree of progression of cancer has
                        been shown to predict survival
--------------------------------------------------------------------------------
Stratifying Dx/         A diagnostic used to stratify a clinical patient
Companion Dx            population with the purpose of delivering clinical
                        utility

Anatomical              Branch of pathology that is concerned with the diagnosis
Pathology               of disease based on the gross and microscopic
                        examination of cells and tissues
--------------------------------------------------------------------------------
Histopathology          Is a field of anatomical pathology which specializes in
                        the histologic study of diseased tissue. It used for
                        accurate diagnosis of cancer and other disease
--------------------------------------------------------------------------------
Cytopathology           Is a field of anatomical pathology which studies and
                        diagnoses diseases on the cellular level. The most
                        common use of cytopathology is the Pap smear, used to
                        detect cervical cancer at an early treatable stage
--------------------------------------------------------------------------------
Flow Cytometry          Technique for counting, examining and sorting
                        microscopic particles suspended in a stream of fluid. It
                        allows simultaneous multiparametric analysis of the
                        physical and/or chemical characteristics of single
                        cells. It is the main technology used today to diagnose
                        the different types of leukemia and lymphoma
