Epidemiological investigation and analysis of cervical cancer in 18 365 elderly women in rural area of Dongying

OBJECTIVE To investigate the epidemiological condition of cervical carcinoma in elderly women in rural areas of Dongying City in Shandong Province.METHODS A total of 18 365 women were collected and analyzed by gynecological examination,color ultrasound,vaginal and cervical secretions smear microscopy examination,cervical exfoliated cells of liquid based cytology(TCT)detection.The women with suspicious or abnormal results were examined by colposcopy and cervical tissue multipoint biopsy.RESULTS Totally 4 796 cases out of 18 365 women were detected with gynaecologic diseases(26.11%),including genital tract inflammation 16.23%(2 980/18 365),cervical intraepithelial neoplasia(CIN)3.79%(680/18 365),cervical cancer 0.15%(28/18 365).The median ages of CIN and invasive cancer were both located in the 41 to 50age group.The incidence of invasive cancer in 35-40 and 41-50years-old group were not significantly higher than that of 51-60years-old group(P0.05).The median age of CIN Ⅰ,Ⅱ,Ⅲand invasive cervical carcinoma were respectively in 42.5,45.5,48.5and 49.5years-old groups.CONCLUSIONS CIN and cervical cancer incidence of Dongying is still high.Intensify efforts to free screening,targeted to develop cervical cancer check for different age groups can improve the efficiency of CIN and cervical cancer diagnosis.Correct treatment and follow-up of screened cervical cancer and CIN can effectively decrease the occurrence of cervical cancer.
