Cancer Research and Clinic 2008;20(6):400-402
Objective To discuss the relationship age and pathologic type, tumor size (≥4 cm) and pelvic lymph metastasis in cervical cancer, and the relative factors of cervical cancer with metastasis of pelvic lymphaden and the possibility of ovarian conservation. Methods 166 cases of cervical cancer accepted radical hysterectomy and pelvic lymphadenectomy in our hospital from June 2002 to June 2007, and were analyzed retrospectively. 166 cases of cervical cancer were divided into two groups, the age in group A was less than 35, while in group B was more than 35. Results The possibility of adenocarcinoma, the tumor size (≥4 cm) and the metastasis of pelvic lymphaden were higher in group A than in group B. The higher the clinical stage, the higher the pathological type and grade were. The greater the tumor size were ,the higher the rate of pelvic lymphatic metastasis (P <0.01). The more tissue infiltrate were, the higher the rate of pelvic lymphatic metastasis (P <0.01). Conclusion The possibility of adenocarcinoma carcinoma, the tumor size (≥ 4 cm) and the metastasis of pelvic were more higher in young women. The rate of pelvic metastasis is closely related to clinical stage, pathological type and grade, tumor size, and tissue infitration.

Journal of Practical Obstetrics and Gynecology 2010;26(2):124-127,插1
Objective:To investigate the amplification of the telomerase RNA component (TERC) gene in cervical cancer and cervical intraepithelial neoplasia (CIN) using dual-color interphase fluorescence in situ hybridization (FISH) and its significance in screening of cervical lesion. Methods:Cervical cast-off cell specimens were screened from 120 outpatients with cervical lesion, including normal cell from liquid based cytology (20 cases), CIN Ⅰ , Ⅱ , Ⅲ and cervical cancer cell from liquid based cytology (each of 25 cases). The amplification of TERC gene in cervical cast-off cells was detected by dual-color interphase FISH. The results of normal samples were used to set up the threshold. Results:①The percentages of abnormal cells in CIN Ⅰ , Ⅱ , Ⅲ and cervical cancer were significantly higher than threshold value ( P<0.05), and the percentage of abnormal cells was increased with the serious degree of pathological grade (P<0.01) ; ②The percentagesof 2:3,2:4,2:5 and great than or equal to 4:4 types in CIN Ⅰ , Ⅱ , Ⅲ and cervical cancer were significantdifferences (all P<0.01). The percentages of 2:4,2:5 and great than or equal to 4:4 types in cervical cancer were significant higher than that in CIN Ⅰ (P<0.001) while the percentage of 2:3 type was significant lower than that in it (P<0.001);③The percentage of abnormal cells was increased with the serious degree of cytological grade (P<0.01) in different cytological grades. The percentages of 2:3,2:5 and great than or equal to 4:4 types in atypical squamous cell of undetermined significance (ASCUS), low-grade squamous intraepithe-lial lesions (LSIL) and high-grade squamous intraepithelial lesions (HSIL) were significant differences (all P <0.01), and the percentages of 2:5 and great than or equal to 4:4 types in HSIL were significant higher than that in ASCUS( P <0.01) while the percentage of 2:3 type was significant lower than that in it ( P <0.01);④The detection rates of LSIL and HSIL with cytological examination in low grade and high grade CIN were 40% (10/25) and 62% (31/50) respectively, which were significant lower than the detection rates of FISH which was 100%(P<0.05).Conclusions:There is an abnormal amplification of TERC gene in CIN Ⅰ , Ⅱ , Ⅲ and cervical cancer, and its copy numbers are increased with the serious degree of pathological and cytological grades. Detection of amplification of TERC gene in cervical cast-off cells with FISH has a certain value for screening cervival lesion and prediction of lesion progression.
