摘      要：Objective： To investigate the relationship between the expression of Fas and Fas ligand （FasL） and its biological behavior in human cervix carcinoma. Methods： Immunohistochemisty technique was used to detect the expression of Fas and FasL in 47 cases of cervical carcinoma, 16 cases of cervical interaepithelial neoplasia, 10 cases of chronic cervicitis and 10 cases of normal cervix. TUNEL technique was used to observe the apoptic cells in 47 cases of cervical carcinoma. Retrospective study was carried out to find the relationship between the expression of Fas and FasL and cell apoptosis, clinical stage, pathological classification, lymph node metastasis, prognosis and age. Results： The expression of Fas and FasL was significantly different in different cervix （P 〈 0.01）, and also related to the degree of differentiation, lymph node metastasis and prognosis （P 〈 0.05）. But had no relation with clinical stage or age （P 〉 0.05） ; Cervix carcinoma cells apoptosis in different pathological classification appeared negative relation （Rs=-0.35, P 〈 0.05 ）. Cervix carcinoma cell apoptosis was significantly higher in Fas-positive and FasL- positive than that in Fas-negative and FasL-negative （P 〈 0.05）. By retrospective investigation, Fas-negative and FasL-positive were related to poor prognoses of the patients with cervical carcinoma （P 〈 0.05 ）. Conclusion： The development of apoptosis in cervix carcinoma has a promoting regulation function in Fas and FasL expression. Gene treatment can alter apoptosis abnormality, thus induce apoptosis in cancerous cell expressing Fas and FasL. Fas or FasL may be taken as a marker in the prognostic character- ization.
