Analysis of diagnosis and treatment of 750 patients with cervical intraepithelial neoplasia / 中国综合临床

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.
