ABSTRACT
Objective@#To explore the indication and surgery scope for laparoscopic extraperitoneal lymphadenectomy in locally advanced cervical cancer.@*Methods@#Laparoscopic extraperitoneal lymphadenectomy was initially performed on patients with locally advanced cervical cancer. The results of preoperative computed tomography (CT) images and serum level of squamous cell carcinoma antigen (SCC-Ag) were analyzed, and the diagnostic efficiencies of the minimum axial diameter (MAD) of lymph node on CT≥0.5 cm, ≥1.0 cm, serum level of SCC-Ag alone or combined to predict the extraperitoneal lymph node metastases were compared. The high-risk factors of common iliac lymph node (CILN) and para-aortic lymph node (PALN) metastases were also analyzed.@*Results@#The lymph node metastasis rate of 81 patients who received the laparoscopic extraperitoneal lymphadenectomy was 59.3% (48/81). The CILN and/or PALN metastasis rate was 24.7%(20/81), and among them, the MAD of CILN and/or PALN ≥0.5 cm on CT images were in only 7 patients. The threshold of SCC-Ag for evaluating lymph node metastasis was 4.8 ng/ml. The accuracy, specificity and Youden index of SCC-Ag≥4.8+ MAD≥1.0 cm group for predicting lymph node metastasis were 78.3%, 100% and 0.6, respectively, and were significantly higher than 57.9%, 12.1% and 0.1 of MAD≥0.5 cm group, 71.1%, 75.8% and 0.4 of MAD≥1.0 cm group, 65.0%, 57.7% and 0.3 of SCC-Ag≥4.8 ng/ml group and 68.3%, 65.4% and 0.4 of SCC-Ag≥4.8 ng/ml+ MAD≥0.5 cm group (P<0.05). All of the 21 patients in SCC-Ag≥4.8 ng/ml+ MAD≥1.0 cm group were detected to occur lymph node metastases, and the metastasis rate of CILN and/or PALN was 38.1%. While only 4 cases of 17 patients in SCC-Ag<4.8 ng/ml+ MAD<1 cm group were confirmed to occur CILN metastases. The difference of lymph node metastasis rate between these two groups was statistically significant (P<0.001). The pathological type, the number of PLN with MAD≥1.0 cm, at least one of the PLN MAD≥1.0 cm and/or MAD of CILN and/or PALN was 0.5~1.0 cm were associated with the CILN and/or PALN metastases (all P<0.05).@*Conclusions@#Those patients with MAD≥1.0 cm+ SCC-Ag≥4.8 ng/ml and with high-risk factors of CILN and/or PALN metastases should undergo laparoscopic extraperitoneal lymphadenectomy to provide explicit guidance for the subsequent therapy. However, the incidence of lymph node metastasis of patients with SCC-Ag<4.8 ng/ml combined with MAD<1.0 cm is low, therefore these patients can accept concurrent chemoradiotherapy directly.
ABSTRACT
Objective@#To introduce the laparoscopic type C1 hysterectomy based on the anatomic landmark of the uterus deep vein and its branched and to evaluate its feasibility and safety for cervical cancer and its effect to bladder function and to provide some reference to simplify the surgical procedures of laparoscopic type C1 hysterectomy.@*Methods@#The clinicopathologic data of the patients with stage ⅠA2~ⅡB cervical cancer and who underwent the laparoscopic C1 hysterectomy based on anatomic landmark of the uterus deep vein and its branches between March 2010 and December 2015 was retrospectively analysed.@*Results@#A total of 99 patients received laparoscopic type C1 hysterectomy based on the anatomic landmark of the uterus deep vein and its branches, in which 93 patients reserved unilateral or bilateral pelvic autonomic nerve successfully, the other 6 patients were transfered to receive type C2 hysterectomy due to adhesions, bleeding or the low possibility of curative resection. The failure rate of the surgery was 6.1% (6/99). The average age of these 93 patients was 44.4±8.2 years (range 25~61 years) and there was one case of stage ⅠA2, 84 stage ⅠB1, 2 stage ⅠB2, 5 stage ⅡA1 and 1 stage ⅡB. The number of patients with squamous cell carcinoma was 67, adenocarcinoma was 19, adenosquamous carcinoma was 3, small cell neuroendocrine carcinoma was 3 and mixed type was 1. The average operation time was 4.1±0.5 h, the average amount of intraoperative blood loss was 103.8±84.0 ml and the mean number of excisional pelvic lymph nodes was 29.7±8.9. There was no patient with positive parametrial margin, positive vaginal margin or intraoperative ureteral injury. The postoperative catheter extraction time was 20.3±8.4 d. The median follow-up time was 20 months (rang 5~44 months), the long-term bladder dysfunction rate was 8.6% (8/93). The numbers of locally uncontrolled and distantly metastasis case were both one and both patients died. The fatality rate were 2.2% (2/93). The two-year disease-free survival and overall survival rate were 97.6% and 96.2%, respectively.@*Conclusion@#Laparoscopic type C1 hysterectomy based on the anatomic landmark of the uterus deep vein and its branches is a safe and feasible treatment method for cervical cancer and it provides a new approach for simplifying the surgical procedures of laparoscopic type C1 hysterectomy.
ABSTRACT
Objective To investigate the relationship between adhesion molecule CD44v6,intercellular adhesion molecule-1 (ICAM-1) and lymph node metastasis in early stage of cervical squamous cell carcinoma.Methods Seventy-four specimens of cervical cancer stage Ⅰ b1,20 specimens of normal cervical tissue and 20 specimens of cervical squamous cell in situ carcinoma were collected from Jiangxi Provincial Maternal and Child Health Care Hospital.The expression of CD44v6 and ICAM-1 in cervical tissue was detected by real-time PCR and immunohistochemistry.The lymphatic vessel density (LVD) labeled by D2-40 was detected by immunohistochemistry.The relationship of CD44v6,ICAM-1 and LVD with the differentiation degree and lymph mode metastasis was investigated.Results The positive expression rate of CD44v6 and ICAM-1 in normal cervix,cervical squamous cell carcinoma in situ,and cervical carcinoma tissues was gradually increased,which were 0,75.00％,87.84％ and 10.00％,45.00％,81.08％ respectively.Their mRNA expression amount was gradually increased,which were 0,0.24±0.02,1.02±0.11 and 0.10 ± 0.00,0.19±0.02,1.03 ± 0.10 respectively,the differences were statistically significant (P＜0.01).LVD was gradually increased in normal cervix,cervical squamous cell carcinoma in situ,and cervical carcinoma (P＜0.01).The expression of CD44v6,ICAM-1 and LVD in low differentiated cervical carcinoma tissue was higher than that in high and middle differentiated cervical carcinoma (P＜0.01).The expression of CD44v6,ICAM-1and LVD in lymph node metastasis was higher than that in non-lymph node metastasis (P＜0.01).The expression of CD44v6,ICAM-1 and LVD in cervical cancer tissue had each two positive correlation (P＜0.01).Conclusion CD44v6 plays a promoting role in the progression of cervical cancer,which with ICAM-1 and LVD synergically promote the cervical cancer development,and could be used as an effective indicator for judging lymph node metastasis and diagnosis of cervical cancer.
ABSTRACT
Objective Compare the complications between laparoscopic and abdominal cervical cancer surgery, and investigate the safety of laparoscopic cervical cancer surgery and complications classified by Clavien-Dindo classification, then analyze the risk factors. Method Clinical data of 215 cases of cervical cancer received surgery from March 2011 to October 2014 was collected, which include intraoperative, postoperative and postoperative fol﹣low-up data. All the cases were divided into two groups: LRH group (n= 116) and ARH group (n= 88), then ana﹣lyze and compare the difference of intraoperative, postoperative complications and postoperative follow-up data be﹣tween the two groups, assess the safety of the two groups, and statistically concluded related independent risk factors. Results The complications of 204 patients were classified into 4 grades. The criticality and morbidity of intraopera﹣tive and postoperative complications have no significant difference between the two groups (P> 0.05). Logistic re﹣gression analysis show that over criticality grade Ⅱ of LRH intraoperative complication related to operating time, over criticality grade Ⅱ of ARH intraoperative complication related to aged over 50 yr, over criticality grade Ⅱ of ARH intraoperative complication related to BMI> 25. Conclusions Through the analysis of laparoscopic operation and the criticality of complications, the safety of the two groups were no difference. The patients with high risk fac﹣tors should be evaluated comprehensively. And strictly grasp the contraindication and indication.
ABSTRACT
Objective To investigate the risk factors of cervical cancer in Chinese married women in recent 10 years in order to provide evidence based approaches for cervical cancer prevention and control Methods Eight case-control studies from 2002 to 2011 were selected from research literatures by using keywords such as cervical cancer, risk factors, influential factors and case-control study, cancer, risk factors, factors andcase-control study as the search term.We adopted the Mentel-Haensel fixed effect model and Dersimonion-Laird random effect model to gain a comprehensive and quantitative assessment of cervical cancer and its risk factors.Results Among the 8 case-control studies,the total number of cases and controls were 2868 and 8045,respectively.The risk factors included human papilloma virus (HPV) (RR =5.47,95 ％ CI:3.40-8.82),family history of cervical cancer (RR =2.40,95 ％ CI:1.39-4.16),number of abortions (RR =1.74,95％ CI:1.49-2.03),first sexual intercourse age number of sexual partners (1.72,95％ CI:1.36-2.16),low cultural level (RR =1.68,95％ CI:1.18-2.40).Conclusion The major risk factors for cervical cancer among married women in China included HPV,family history of cervical cancer,number of abortions,first sexual intercourse age number of sexual partners and low cultural level.
ABSTRACT
Objective To analyze the clinicopathologic features of mucinous cervical adenocarcinoma (ADC) and supply some reference for its diagnosis,treatment and prognosis.Methods Totally 88 cases with primary mucinous ADC diagnosed between January 2003 and December 2007 in Jiangxi Maternal and Child Health Hospital were retrieved.Their clinical and pathological data were reviewed and analyzed.Results Among 88 patients,70 cases of them were endocervical ADC,11 cases were minimal deviation adenocarcinoma (MDA),2 cases were intestinal subtype and 5 cases were villoglandular ADC.The positive rate of cervical Pap smear cytology was only 28％ (10/36).There were 10 cases were performed several times of cervical Pap smear cytology test and biopsies,while still no abnormality was found.Finally,7 cases of them were diagnosed by cervical excisional biopsy and endocervical curettage,including 5 cases with endocervical ADC and 2 cases with MDA; 2 cases (1 case with stage Ⅰ b1 endocervical ADC and 1 case with Ⅰ b1 MDA) were diagnosed by cold knife conization,and 1 case with stage Ⅰ b1 endocervical were diagnosed by uteroscopically directed biopsy.The overall 5-year survival rate was 60.0％.Using univariate analysis results showed that age (P =0.046),stage (P =0.007),tumor size (P =0.007) and therapeutic methods (P =0.009) were significant prognostic factors.Multivariate analysis showed that therapeutic methods was an independent predictor for survival (P =0.013).Stage Ⅱ b-Ⅲ b MDA patients occupied 7/11 of all MDA patient,while there was only one such patient of 5 cases with villoglandular ADC.The overall HPV infection rate was 65％ (57/88),and there was no obvious differences about the HPV infection rates among different types of mucinous ADC.Conclusions Cervical smear cytology is of little significance to the diagnosis of mucinous cervical adenocarcinoma.Early stage mucinous ADC is difficult to be detected,especially for MDA.Cervical excisional biopsy,endocervical curettage,cold knife conization,uteroscope are beneficial to its diagnosis.Therapeutic methods is an important prognostic factor for mucinous ADC and comprehensive treatment should be given to those patients with risky postsurgical factors.
ABSTRACT
Objective To compare the clinical effects and side events between simple synchronal radiochemotherapy(group A) and cervical local implantation chemotherapy combined with synchronal radiochemotherapy(group B) in advanced cervical cancer.Methods Sixty patients with primary cervical cancer,admitted to our hospital from January 2009 to December 2009,were enrolled into the study.The clinical staging of these patients ranged from Ⅱb to Ⅲb.The patients were randomly divided into two different therapy groups.In group A,patients received external irradiation by X-rays and intracavitary by 192 Ir and PT chemotherapy(n=30).In group B,patients received cervical local implantation of fluorouracil palliative 400-500 mg in addition of external irradiation by X-rays and intracavitary by 192 Ir and PT chemotherapy(n=30).The short-term effect and complications were compared between the two groups.Results The effective rate of group A was significantly higher than the second group(97% vs.80%,x2=4.706,P＜ 0.05).The most common complication was myelosuppression.In group A we observed 8 cases had grade Ⅰ,10 cases had grade II,9 cases had grade Ⅲ,3 cases had grade Ⅳ myelosuppression.In group B we observed 8 cases had grade Ⅰ,12 cases had grade Ⅱ,7 cases had grade Ⅲ,3 cases had grade Ⅳ myelosuppression.There were no significantly differences in the comparisons of this complication between the two groups(x2=0.432,P＞0.05).Conclusion The cervical local implantation chemotherapy combined with synchronal radiochemotherapy might improve the prognosis in advanced cervical cancer patients without increasing toxic side effects.

ABSTRACT
Objective To evaluate the feasibility and safety of vaginal enlarged amputation of cervix to treat patients with cervical cancer of stage Ⅰ a1 and cervical intraepithelial neoplasia grade Ⅲ(CIN Ⅲ)who were unfit for conization surgery.Methods From July 2002 to May 2007,patients with cervical cancer at stage Ⅰ a1,diagnosed by pathology after loop electrosurgical excision procedure(LEEP),large area CIN Ⅲ(the area of lesion≥3/4 on colposcopy),CIN Ⅲ coexisted with vaginal intraepithelial neoplasia (VAIN)in the superior segment of vagina,CIN Ⅱ-Ⅲ recurrence or with residual lesion,positive margin after conization of cervix,who wanted to preserve fertility and(or)corpus uteri were selected to receive vaginal enlarged amputation of cervix.Results Forty-eight eases including 5 with cervical cancer in stage Ⅰ a1,38 with large area CIN Ⅲ(9 with gland involvement),2 with residual lesion and 2 with positive margin after LEEP,1 recurrence after cold knife conization,received the procedure successfully.The median age was 34 years(range 27-40),median operation time was 60 minutes(range 30-100),median blood loss was 40 ml(range 5-300),and median hospital stay was 10 days(range 7-17).After follow-up 1-39 months,no patient had postoperative complications and recurrence,and all patients resumed normal menstrual cycle and sexual life.Condusion Vaginal enlarged amputation of cervix appears to be a safe and feasible procedure for patients with cervical cancer at stage Ⅰ a1 and CIN Ⅲ who are unfit for conization surgery.
ABSTRACT
Objective To investigate the risk factors for ovarian metastasis and the possibility of ovarian preservation in patients with endometrial carcinoma.Methods The clinicopathological features of endometrial carcinoma patients who were diagnosed and treated initially with a surgical staging procedure from Jan 1997 to Dec 2006 in our hospital were retrospectively reviewed.Results Of the 638 cases reviewed,36(5.6%,36/638)had ovarian metastasis.Univariate analysis revealed that histological type and grade,myometrial invasion,positive peritoneal fluid cytology,pelvic lymph node metastasis,invasion of parauterine,para-aortic node metastasis and invasion of uterine serosa were significantly associated with ovarian metastasis(P＜0.05);while age,lymph-vascular invasion and cervical invasion wen not significantly associated with ovarian metastasis(P＞0.05). Factors predictive of ovarian metastasis by multivariate analysis were ranked as follows according to risk intensity:pelvic lymph node metastasis,positive peritoneal cytology,and histological grade.Conclusion In young patients with grode 1 endometrioid carcinoma,with no pelvic lymph node metastasis,no para-aortic lymph node metastasis,no myometrial invasion and with negative peritoneal fluid cytology,ovarian preservation could be considered.
ABSTRACT
Objective To analyze the changes in epidemiology and treatment of hospitalized patients with cervical cancer during 1990-2007.Methods Overall.4648 patients witIl cervical cancer were diagnosed in our hospital from Jan 1990 to Nov 2007.but only 4223 patients with initial treatment in Oily hospital were studied retrospectively.Pearson Chi-square test was used to compare tlle age,stage,histopathologie type and treatment metheds between different times.Results (1)The meal]age of cervical cancer patients gradually decreased over the past 18 years,from 54.4 years during 1990-1999 to 47.2 years during 2000-2007:the proportion of young patients aged≤35 years increased from 4.77%(89/1865)during 1990-1999 to 11.75%(277/2358)during 2000-2007.(2)The proportion of patients with cervical cancer(stage I a-H a)increased from 14.32%(267/1865)during 1990-1999 to 40.75%(961/2358)during 2000-2007,whereas the proportion of patients with cervical cancer(stage Ⅱ b-lV)decreased from 85.68%(1598/1865)during 1990-1999 to 59.25%(1397/2358)during 2000-2007.(3)There was no significant change in histopathologie type of cervical cancer,and squamous cell careinoma of cervix remained the main type of cervical cancer.(4)The treatment pattern of cervical cancer changed significantly:radiotherapy was the main method(75.28%)for eervical cancer during 1990-1 999.but during 2000-2007.it was replaced by concurrent chemoradiotherapy(35.79%).Conclusions The proportion of young women with cervical cancer was increased during 1990-2007.and at the same period early stage cervical cancer increased.but late stage cervical cancer decreased.It is obvious that chemotherapy has become the important therapy in cervical cancer.
