N/A Objective: The human MAGE 3 gene encodes tumor specific antigens that are recognized by autologue cytotoxic T lymphocytes (CTL). The MAGE 3 gene is expressed not only in melanoma but in the other malignant tumors as well. There is, however, little information on the expression of the gene in uterine cervical carcinomas. The author thus studied the expression of the MAGE 3 gene products in uterine cervical carcinoma and discuss the possibility of specific immunologic diagnosis using MAGE 3 gene products. Methods: The expression of MAGE 3 gene product in 17 normal tissues of the cervix, 32 cervical intraepithelial neoplasia (8 CINⅠ, 10 CINⅡ, 14 CIS), and 43 invasive cervical carcinomas was studied by immunohistochemistry using anti-MAGE 3 mAb 57B in paraffin sections. Results: No expression of MAGE 3 gene product was detected in normal cervical tissues and in cervical intraepithelial neoplasias. The expression of MAGE 3 gene product was detected in 30.2% (13/43) of invasive cervical carcinomas. The MAGE 3 gene product was stained as a cytoplasmic protein in cancer cells. No statistically significant differences were observed between MAGE 3 gene product expression status and clinicopathologic parameters. Conclusions: The MAGE 3 gene products was expressed in invasive cervical carcinoma tissues.

Objective : Mycoplasmas have been implicated in many diseases including cervicitis, urethritis, salpingitis, endometritis... and functioning as cofactors catalyzing the HIV disease state. The oncogenic potentiality of mycoplasma was only recently realized when they were shown causing chromosomal changes and in vitro cell transformations through gradual progressive chromsomal loss and translocation. Few study has been reported the prevalence of mycoplasma infection in human cancers and suggested that there was a connection between these organisms and human cancers. The objective of this study was to determine the relationship between Ureaplasma urealyticum infection and cervical cancer. Methods : The detection frequency of Ureaplasma urealyticum in 52 invasive cervical cancer tissues and 17 normal cervical tissues was studied using PCR. Results : U. urealyticum DNA was detected in 8 out of 52(15.4%) invasive cervical cancer tissues and 1 out of 17(5.9%) normal cervical tissues. No statistic significance was observed between the detection frequency of Ureaplasma urealyticum and clinicopathologic parameters. The prevalence of Ureaplasma urealyticum in invasive cervical tissues was 15.4% and this rate was higher than 5.9% in normal cervical tissues but there was no statistic significance. Conclusions : With respect to clinicopathologic parameters of cervical cancer, there was no significant relation between U. urealyticum infection and cervical cancer. There is, however, few study and case on cervical cancer internally and externally. It is considered that more studies on the subject with much cases should be made.
