Objectives:
To evaluate the role of rapid immunohistochemistry (RIHC) based on ultrasonic thermal steam heating in improving diagnostic accuracy of intraoperative frozen section diagnosis and to recommend RIHC antibody panels for pathologic differential diagnosis.
Materials And Methods:
RIHC based on ultrasonic thermal steam heating was tested for intraoperative frozen diagnosis with difficulty in diagnosis, and all slides were reviewed and compared with the final diagnosis. Ninety-three cases of surgical specimens involving RIHC examination were studied. Discordance rates with paraffin immunohistochemistry were calculated.
Results:
In 93 cases where RIHC was performed, 85 cases (91%) were proven to be helpful for the diagnosis. A total of 58 antibodies were used for RIHC 276 times, of which 19 antibodies were not effective 25 times. Fifteen RIHC antibody panels are recommended based on staining stability and utilization frequency.
Conclusion:
After improving the staining method, ultrasonic thermal steam heating RIHC is practical, convenient, and cost-effective, making it suitable for use in any pathology department with routine immunohistochemistry reagents. It plays an important auxiliary role in improving the accuracy of intraoperative rapid pathologic diagnosis.
