Methods： Immunohistochemical method （EliVision） was used to detect the expression of AQP1 in samples from 106 patients [20 with normal cervical tissue, 30 with cervical intraepithelial neoplasia （stage Ⅰ and Ⅱ） and 56 with CSC]. Survival analysis was performed by Kaplan-Meier method. Results： AQP1 protein was expressed in vascular endothelia of all samples. It showed upregulation of AQP1 expression in CSC. There was a significant difference between CSC and normal cervical tissues （P〈0.05）. AQP1 was expressed in some tumor cells and unexpressed in normal squamous epithelial cells. And APQl-expressing tumor cells were positively related to lymph node metastasis. Patients with APQl-expressing tumor cells had the lower survival rate than the ones without. Conclusion： Abnormal expression of AQP1 plays an important role in the development of CSC. Positive expression of AQP1 in tumor cells maybe enhances tumor metastasis and could be used as a marker for tumor prognosis.展开更多

METHODS Immunohistochemical staining of tissue microarrays and Western blot analysis were conducted to detect the expression of HMGB1 in the following tissue samples： 30 carcinoma in situ, 90 invasive CSEC without metastasis, 30 invasive CSEC with metastasis, 30 cases of normal cervical squamous epithelia. RESULTS The positive-expression rate of HMGB1 was 58.7% （88/150） in CSEC, showing a significant difference compared to normal cervical squamous epithelia. The expression of HMGB1 was correlated with tumor size, invasion and metastasis of CSEC （respectively, P〈0.01）, but had no relationship with the degree of differentiation （P〉0.05）. CONCLUSION The over-expression of HMGB1 in CSEC might be a useful parameter as an indication of tumor invasion, metastasis, prognosis and overall biological behavior of human CSEC, as well as a noval target site for gene therapy.展开更多

However, the expression and function of CDC42 in cervical squamous cell carcinoma remains unclear. This study aimed to investigate the expression of CDC42 in cervical squamous cell carcinoma and its correlation with clinicopathologic characteristics. Methods： The expression of CDC42 in 162 cervical squamous cell carcinoma tissue samples and 33 normal cervical tissue samples was investigated by immunohistochemistry. The CDC42 mRNA expression was detected by reverse transcription-polymerase chain reaction （RT-PCR）. Results： The cervical squamous cell carcinoma group showed a significantly higher CDC42 positive rate, compared to the normal cervical tissues （P〈0.05）. Fttrthermore, the tissues of stage Ⅱ-Ⅳ carcinoma patients showed higher CDC42 expression levels compared to stage I patients （P=0.05）. In addition, the expression of CDC42 was not correlated to age of patients, differentiation degree of cancer cells, or lymph node metastasis （P〉0.05）. Furthermore, compare with normal cervical tissues, the CDC42 mRNA expression in cervical cancer had no significant difference. Conclusions： CDC42 was up-regulated at protein level, but not mRNA level, in cervical squamous cell carcinoma. The high expression of CDC42 was correlated to the clinical stage of the patients, indicating that CDC42 might contribute to the progression of cervical squamous cell carcinoma.展开更多

Results The overexpression of cyclin D1 and P53 in invasive cervical carcinomas was 70% and 50%, respectively. There was no overexpression of them in the control group. The overexpression of cyclin D1 in grade Ⅱ and Ⅲ was much higher than that in gradeⅠ(P<0.05). The overexpresson of cyclin D1 in stage Ⅲ of cervical carcinoma was significantly higher than that in stage Ⅱ (P<0.05). The overexpression of P53 in grade Ⅱ and grade Ⅲ of cervical carcinoma was remarkably higher than that in grade Ⅰ (P<0.05).Conclusion The action point of both cyclin D1 and P53 may be at G1/S transition. The overexpression of them was associated with development and progression of cervical carcinoma probably in different mechanisms and different pathways.展开更多

Methods The cell proliferation and apoptosis of cervical epithelial cells in archival formalin-fixed, paraffin-embedded tissue sections of normal cervix, cervical intraepithelial neoplasms (GIN) and cervical squamous carcinoma were tested by using immunohistochemistry assay and DNA nick end-labeling technigue. The proliferation index (PI) and apoptosis index (AI) were calculated and their correlation with clinical and pathological data was analyzed.Results PI was gradually increased, but the AI and AI/PI ratio decreased from normal cervical epithelium, GIN to cervical carcinoma. There was no significant relationship among cell proliferation, apoptosis, clinical stages and pathological grades. High AI was always associated with a poor prognosis of the patients.Conclusion Cell proliferation and apoptosis allow to distinguish among normal epithelium, GIN and cervical carcinoma and are useful for the assessment of the malignant potential of tumor tissues.展开更多

METHODS Real time quantitative polymerase chain reaction （qRT-PCR） was employed to examine the expression of HMGB1 （high mobility group box protein1）, and RAGE （receptor for advanced glycation endproducts） in 60 cervical squamous epithelial carcinomas （CSEC）, their paraneoplastic tissues （PS） and 30 normal cervix tissues （NCS）. RESULTS The expression of HMGB1 in the CSEC samples and PS was similar （P〉0.05）, but higher compared to NCS （P〈0.05）. Overexpression of HMGB1 in the CESC tissues was significantly correlated with the tumor （P〈0.05）, and the presence of metastasis （P〈0.01）, but not correlated with the tumor diameter or tumor grade.RAGE expression was not significantly different among these tissue types, and showed no significant correlation with the the tumor stage, diameter or grade. But there was a significant positive correlation between RAGE expression and CSEC metastasis. CONCLUSION The results suggest that HMGB1 may be related to the proliferation, progression and metastasis of CSEC. The relationship of HMGBI/RAGE may be of importance for CSEC metastasis. HMGB1 presents a new potential gene target for prevention and treatment of CSEC. Study of HMGBI/RAGE expression will offer an experimental foundation for understanding the pathogenesis of CSES.展开更多

CONCLUSION The results suggest that HMGB1 may be related to the proliferation, progression and metastasis of CSEC. The relationship of HMGBI/RAGE may be of importance for CSEC metastasis. HMGB1 presents a new potential gene target for prevention and treatment of CSEC. Study of HMGBI/RAGE expression will offer an experimental foundation for understanding the pathogenesis of CSES.
文摘Background：Pelvic lymph node metastasis （LNM） is an important prognostic factor in cervical cancer.Cervical squamous cell carcinoma accounts for approximately 75-80% of all cervical cancers.Analyses of the effects of the number of positive lymph nodes （LNs）,unilateral vcrsus bilateral pelvic LNM and a single group versus multiple groups of pelvic LNM on survival and recurrence of cervical squamous cell carcinoma are still lacking.The study aimed to analyze the effects of the number of positive pelvic LNs and a single group versus multiple groups of pelvic LNM on survival and recurrence.Methods：We performed a retrospective review of 296 patients diagnosed with Stage ⅠA-ⅡB cervical squamous cell carcinoma who received extensive/sub-extensive hysterectomy with pelvic lymphadenectomy/pelvic LN sampling at Peking University People＇s Hospital from November 2004 to July 2013.Ten clinicopathological variables were evaluated as risk factors for pelvic LNM：Age at diagnosis,gravidity,clinical stage,histological grade,tumor diameter,lymph-vascular space involvement （LVSI）,depth of cervical stromal invasion,uterine invasion,parametrial invasion,and neoadjuvant chemotherapy.Results：The incidence of pelvic LNM was 20.27% （60/296 cases）.Pelvic LNM （P =0.00） was significantly correlated with recurrence.Pelvic LNM （P =0.00）,the number of positive pelvic LNs （P =0.04） and a single group versus multiple groups of pelvic LNM （P =0.03）had a significant influence on survival.Multivariate analysis revealed that LVSI （P =0.00）,depth of cervical stromal invasion （P =0.00）and parametrial invasion （P =0.03） were independently associated with pelvic LNM.Conclusions：Patients with pelvic LNM had a higher recurrence rate and poor survival outcomes.Furthermore,more than 2 positive pelvic LNs and multiple groups of pelvic LNM appeared to identify patients with worse survival outcomes in node-positive ⅠA-ⅡB cervical squamous cell carcinoma.LVSI,parametrial invasion,and depth of cervical stromal invasion were identified as independent clinicopathological risk factors for pelvic LNM.
文摘Background Tumor intrinsic chemoradiotherapy resistance is the primary factor in concomitant chemoradiotherapy failure in advanced uterine cervical squamous cell carcinoma. This study aims to identify a set of genes and molecular pathways related to this condition.
