Résumé
Objective To evaluate the clinicopathological characteristics and prognosis of cervical adenocarcinoma patients with stage Ⅰ b1-Ⅱ b treated with radical hysterectomy and systematic lymphadenectomy.Methods The clinical,pathologic and follow-up data of 118 cases of cervical adenocarcinoma with stage Ⅰ b1-Ⅱ b treated with radical hysterectomy and systematic lymphadenectomy in Cancer Hospital of Shantou University Medical College from Dec.2003 to Nov.2015 were analyzed retrospectively.Results 118 patients of cervical adenocarcinoma with stage Ⅰ b1-Ⅱ b had a median age of 46 years at diagnosis.28 cases were postmenopausal and 90 cases were premenopausal.There were 77 cases in phase Ⅰ b1,25 in stage Ⅰ b2,4 in stage Ⅱ a1,7 in stage Ⅱ a2,5 in stage Ⅱ b.The rate of ovarian metastasis was 3.39％.The 3-year recurrence-free survival rate of the patients was 81.6％.The 3-year overall survival rate of the patients was 83.9％,and 89.10％ for stage Ⅰ b1,73.7％for stage Ⅰ b2,100％ for stage Ⅱ a1,83.3％ for stage Ⅱ a2,60.0％ for stage Ⅱ b.The 3-year overall survival rates of the patients who receive non-chemoradiotherapy,chemotherapy,radiotherapy and chemoradiotherapy after operation were 90.6％,100％,84.6％ and 70％ respectively.The result of Cox proportional hazards regression model analysis indicated that lymph lode metastasis and ovarian metastasis was the independent prognostic factor of desease-free survival,ovarian metastasis and deep myometrial invasion was the independent prognostic factor of overall survival.Conclusions Premenopausal cases are more common than postmenopausal cases in cervical adenocarcinoma with stage Ⅰ b1-Ⅱ b.Ovarian presevation is feasible for early-stage cervical denocarcinoma after full assessment.Pelvic irradiation with concurrent chemotherapy can lead a better prognosis for the patients with pathological risk factors.
Résumé
Objective To discuss about the relationship between the occurrence of the uterine cervix cancer and the risk factors.MethodsAmong the patients we collected,92 patients were diagnosed to have the cervical cancer,63 patients were diagnosed as CINⅢ (the cervical intraepithelial neoplasia,CIN),and 252 patients belonged to the control group.All patients had not been cured before.We used the questionnaire to investigate them about the dietary habit and other information.Through using different statistical Methods ,we explored the relationship between the cervical cancer and the potential factors.ResultsWe found out that many factors contributed to the happening of the cervical cancer,such as gynecopathy(χ2=19.31,P＜0.01),the first time of the menses(F＝11.62,P＜0.01),the first time of the sex life(F＝25.76,P＜0.01),the first time of the parturition (F＝28.02,P＜0.01),the times of the pregnancy and the parturition(F1＝13.98,P1＜0.01;F2＝4.78,P2＜0.01),the culture degree(χ2＝10.70,P＜0.05),the infection of HPV(χ2＝179.95,P＜0.01),the level of the folic acid (F＝3.39,P＜0.05) and so on.The result of the logistic regression analysis showed that keeping the habit of drinking tea(OR＝0.321,β＝-1.136,P＜0.05),paying attention to the sanitation of the sex life(OR＝0.387,β＝-0.950,P＜0.05),putting off the first time of the sex life(OR＝0.551,β＝-0.596,P＜0.05),and the higher level of the folic acid (OR＝0.502,β＝-0.688,P＜0.05) were the protective factors tothe occurrence of the uterine cervix cancer.Meanwhile,the infection of the HPV(OR＝27.215,β＝3.304,P＜0.01),many times of the parturition(OR＝1.846,β＝0.613,P＜0.05) and the passive smoking (OR＝1.673,β＝0.515,P＜0.05) were the risk factors.ConclusionsWith the higher level of the folic acid,the less possibility you will get the cervical cancer.There exists many measures to prevent the happening of the cervical cancer,like keeping the healthy sex life,keeping far away from the passive smoking,not to give birth too early or too many and preventing being infected the HPV.What's more,having the good habit of drinking tea and paying attention to the supplement of the folic acid and Vitamin B12 may be the effective method to prevent the occurrence of the cervical cancer.
Résumé
Objective The cell proliferation, cell cycle, apoptosis and the impact of senescence after RNAi were performed. This research provided a theoretical and experimental basis of the prevention and treatment of cervical cancer. Methods According to DEK nucleotide sequence in G enebank, 56 nt o1igonucleotide fragment containing specific target DEK sequence was designed with computer software, and the fragnent was synthesized and cloned into the eukaryotic expressed plasmid vector psiRNA-hH ineo.Then it was transfected into CaSki cells by lipofectamine. DEK mRNA and protein expression were detected to verify the gene silence effect by RT-PCR and Western blot analysis. CaSki cell proliferative inhibition rates were accessed by MTT assay at the 48th hour after DEK siRNA transfection, at the same time cell cycle and cell apoptosis were analyzed by flow cytometry, and SA - β-galactosidase enzyme cytochemiatry was used to identify cell senescence. Results DEK mRNA and protein expression was significantly reduced in psiRNA- hHDEK transfected CaSki cells(0. 28 ±0. 02). Cell proliferation was decreased, cell cycle was inhibited, and cell apoptosis and senescent cells were increased afar DEK gene was silenced. Concluslon DEK siRNA eukaryotic expression vector was successfully constructed and DEK gene expression of CaSki cells was effectively silenced. DEK gene silencing could induce CaSki cells into apoptosis and senescence.DEK gene played an important role in the occurrence and evolution of cervical cancer, which was not only a senescence suppressor gene but also an apeptosis suppressor gene.
