Immunocytochemical methods in haematology and oncology

Area of Science:

• Hematology
• Oncology
• Cell Biology

Background:

• Immunocytochemical investigations of fixed cells are crucial for improving diagnostic accuracy in hematology and oncology.
• Established methods include alkaline-phosphatase/anti(alkaline phosphatase), immunoperoxidase, and avidin-biotin techniques.
• Tyramide-enhanced immunostaining represents a novel and potent advancement in the field.

Purpose of the Study:

• To review the applications and results of immunocytochemistry in diagnosing various hematological and oncological disorders.
• To highlight the utility of tyramide-enhanced immunostaining for cell analysis.
• To demonstrate the supportive role of immunocytochemistry in morphological cell analysis.

Main Methods:

• Analysis of peripheral blood smears and cytospins of mononuclear blood leukocytes.
• Application of immunocytochemical techniques including alkaline-phosphatase/anti(alkaline phosphatase), immunoperoxidase, and avidin-biotin.
• Utilizing novel tyramide-enhanced immunostaining for enhanced sensitivity.

Main Results:

• Immunocytochemistry is effective in analyzing bone marrow, cerebrospinal fluid, serous effusions, and fine-needle aspirates.
• The review details immunocytochemistry results in B- and T-lymphoproliferative disorders, acute leukaemias, and Hodgkin's disease.
• These methods successfully detect epithelial malignant cells, supporting morphological analysis.

Conclusions:

• Immunocytochemistry significantly aids in the accurate diagnosis of hematological and oncological conditions.
• Tyramide-enhanced immunostaining offers a powerful new tool for immunocytochemical analysis.
• The integration of immunocytochemistry with morphological analysis improves diagnostic outcomes for various cancers and blood disorders.
