ABSTRACT

Objective To explore the different probability of carcinoma and the necessity of treatment in cervical columnar ectopy (CCE),normal smooth cervix and cervical intraepithelial neoplasia(CIN) by investigating the different expression of matrix metalloproteinase-9(MMP-9).Methods The expression of MMP-9 was detected by using immunohistochemical method in 30 cases of CCE,28 cases of CIN and 30 cases of normal smooth cervix from 2007 to 2012.Results The positive expression of MMP-9protein in CIN was 96.4% (27/28),CCE was 23.3% (7/30) and normal smooth cervix was 20.0% (6/30)respectively.The positive expression of MMP-9 protein was higher in CIN than CCE and normal smooth cervix,the difference has statistical significance (P< 0.01),there was no significant difference between CCE and normal smooth cervix (P > 0.05).Conclusions CCE,which was a physiological performance of cervical erosion,should not be overtreated.But the women of childbearing age should be routinely performed in cervical cancer screening.

ABSTRACT

Objective To investigate the diagnosis and treatment of cervical intraepithelial neoplasia and their clinical effect Methods The cases who were diagnosed as CIN through cytology, colposcopy biopsy and histopathological diagnosis were collected from January 2004 to June 2009 in Songjiang Hospital Affiliated to Shanghai Jiaotong University School. Drug therapy, physical therapy, cervical conization and hysterectomy were performed according to the lesion degree of CIN and patients' willingness. Some cases were further treated with surgery, radiotherapy or chemotherapy according to the pathological findings of the initial excision specimens. With long-term follow-up at 6,24 months after the treatment,we performed a comparative analysis on pathological diagnosis and therapeutic effects. Results Seven hundred and fifty cases of CIN were diagnosed after cervical cancer screening,among which,460 cases of CIN Ⅰ ,180 cases of CINⅢⅡ and 110 cases of CIN Ⅲ. Five hundred and Senventy-eight cases received treatment, among which, 46 cases received drug treatment After 6 months, focus disappeared in 32 cases, sustained in 10 cases, upgraded in 2 cases and canceration occurred in 2 cases. 13 cases received physical therapy,no recurrence occured. Four hundred and thirty-five cases received conization treatment, 34 cases with focus upgraded and 4 case recurred after the operation. 84 cases received hysterectomy, of which, 11 cases focus upgraded after the operation and no recurrence. The cases with focus upgraded or recurred all received additional treatment. The effective rate of physical therapy,conization treatment and hysterectomy on all grades of CIN was more than 98% at 2 years, and 69. 7% of drug treatment. The omission diagnostic rate of colposcopy guided biopsy on invasive carcinoma was 2. 2% , and the residual rate of focus of hysterectomy specimens after conization was 16. 2% . Conclusion Colposcopy including multi-point biopsy has high accuracy and specificity in early diagnosis of CIN . Cervical conization is the main method of the treatment of CIN. Patients with CIN Ⅲ and without desire of fertility should consider the removal of the uterus after cervical conization. Drug conservative therapy of CIN should be chosen carefully.

ABSTRACT

One hundred and twenty-two patients with confirmed cervical intraepithelial neoplasia (CIN), as a result of occasional screening for uterine cervix cancer in our out-patient clinic between July 2006 and August 2007, and 122 control patients with cervicitis who received colposcopy during the same period were enrolled in this study. Our results showed that 72% participants didn't receive uterine cervix cancer screening during the past 2 years; 55% women had premarital sexual behavior. CIN was most commonly seen in 30 to 34 year old women. Occasional screening could identify 75% CIN. In comparison with the control group, the incidence of earlier first sexual behavior, marriage, and delivery, multiple pregnancy, and frequent abortion was significantly increased in the study group (P < 0.05). We suggest that increased access to uterine cervix cancer screening might be more important than technical improvement.
