Immunohistochemistry Market Disease Understanding and Treatment Algorithm
Immunohistochemistry (IHC) is a laboratory technique used to detect the presence, location, and amount of specific proteins in cells and tissues, majorly used in diagnosis and treatment of cancer and other chronic diseases such as autoimmune, neurodegenerative and infectious diseases. It involves the following steps:
1.     Sample collection: A biopsy or surgical procedure is used to obtain a tissue sample from the patient.
2.    Sample preparation: To prepare the tissue sample for IHC analysis, it is processed and embedded in a paraffin block.
3.    Antibody staining: Specific antibodies are used to target and bind to particular proteins in the tissue sample. The antibodies are typically labelled with a fluorescent or enzyme-based dye, making the proteins visible under a microscope. 
4.    Image analysis: The presence, location, and quantity of the particular proteins were further determined by examination under a microscope.
5.    Interpretation and diagnosis: A pathologist will make a diagnosis and suggest treatments based on the findings of the IHC analysis.
6.    Treatment: Based on the diagnosis, the patient will receive appropriate treatment, which may include surgery, radiation therapy, chemotherapy, immunotherapy, or a combination of these treatments.
7.    Monitoring: The patient will be closely monitored throughout the treatment process to ensure that the treatment is working and to make any necessary adjustments to the treatment plan
Note - For some cancers, molecular techniques such as Next Generation Sequencing (NGS) are widely used along with IHC to have a more detailed picture and therefore, IHC is just one such other technique not the lone one for the cancer diagnosis and evaluation.

Immunohistochemistry Drugs Key Findings
Some key findings of the IHC drugs market include:
1.    The prevalence of cancer is rising, which is fueling demand for IHC medications because they are used in cancer diagnosis and treatment. This is also causing rapid growth in emerging nations.
2.    Technological developments: Examples include the creation of imaging techniques and more sensitive and focused antibodies.
3.    Increasing public awareness of IHC's advantages: The market for IHC is expanding as more individuals, particularly in developing nations, are becoming aware of IHC's advantages in disease diagnosis.
4.    Market consolidation: A small number of dominant companies, including F. Hoffmann-La Roche, Danaher Corporation, and Merck KGaA, dominate the market, which is highly consolidated.
5.    The frequency with which IHC is used as a companion diagnostic technique to choose patients for targeted therapy has increased.
6.    The high cost of IHC tests and reagents is a barrier to the technology's wide use, particularly in underdeveloped nations.
7.    By minimising the amount of time and human error involved in the process, automated IHC systems are becoming more and more popular.
 
Immunohistochemistry Emerging Drugs
There are several emerging drugs and immunotherapies in the field of immunohistochemistry (IHC) that are currently in various stages of development and clinical trials and it’s to be noted that it will take some time to know their full potential. These include:
1.    BiTE (bispecific T-cell engager) antibodies: These antibodies are made to draw in and activate the patient's own immune cells in order to target and destroy cancer cells.
2.    Checkpoint inhibitors: These molecules on the surface of cancer cells are the target of checkpoint inhibitors, which prevent cancer cells from evading the immune system.
3.    CAR-T cells: These are T cells that have been genetically modified to specifically target and destroy cancer cells in patients.
4.    Antibody-drug conjugates (ADCs): ADCs are a subset of targeted therapy that combine the cellular lethality of cytotoxic medicines with the specificity of monoclonal antibodies.
5.    Immunomodulatory drugs: By controlling the activity of immune cells, they are intended to improve the immune system's capacity to combat cancer.
6.    RNA-based therapies: They use small interfering RNA (siRNA) or messenger RNA (mRNA) to silence or enhance the expression of specific genes in cancer cells
