Abstract:Objective To study the clinical significance of immunohistochemistry technology in tumor pathological diagnosis.Methods One hundred suspected tumor patients admitted in Jiyuan Maternal and Child Health Hospital from June 2020 to June 2022 were studied by conventional techniques and immunohistochemistry. With the pathological results of surgery as the gold standard, the diagnostic efficacy of patients with these two examination techniques was calculated, and SPSS software was used for comparison.Results Of the 100 patients with suspected tumor, 72 patients were diagnosed as tumor by surgical pathological examination. The sensitivity, specificity and accuracy of immunohistochemistry were 97.22%, 96.43% and 97.00%, respectively, higher than 77.78%, 71.43% and 76.00% of conventional techniques (P<0.05).Conclusion Immunohistochemical technology has high clinical value in tumor pathological diagnosis.
