    Abstract:
    OBJECTIVE: To analyze the reported data of national rural cervical cancer screening project from 2012 to 2013 and to evaluate the project implementation condition. METHODS: Data of the national breast carcinoma and cervical cancer (two-cancer) screening project for rural women were collected from the online report system of key women and children's public health service programs.The screening items included: preliminary screening of cervical lesions (cervical cytology, using Traian Bethesda System(TBS) or Pap grading for classification and reporting), acetate/iodide staining (VIA/VILI), colposcopy, histopathological examination, and pathological diagnosis. The study collected the quarterly reported data from 1 183 counties of 30 provinces in 2014 and 1 130 counties of 30 provinces in 2013. Chi-square test was used to test the difference of positive detection rate, as well as precancerous cervical lesions, and cervical cancer detection rates among difference preliminary screening methods in 2012 and 2013. RESULTS: In 2012 and 2013, the number of cervical cancer screening was 10 621 482 and 10 321 835. The percentage of using ThinPrep cytological test as the screening method was 77.17% (n=8 196 627) and 77.07% (n=7 954 949) in 2012 and 2013, respectively. Among these ThinPrep cytological tests in these two years, 65.49% (n=5 368 194) and 71.67% (n=5 701 033) used TBS report system. The abnormality rate of colposcopy increased from 27.29% (170 063/623 161) to 31.15% (203 397/652 935) (χ(2)=2 295.94,P<0.001). The abnormality rate of histopathology test increased from 19.54% (37 992/194 394) to 35.43% (59 004/166 518) (χ(2)=11 523.58, P<0.001). All together, 27 341 cervical cancer or precancerous lesions have been detected in these two years. The detection rate of invasive cervical cancer increased from 18.02/100 000 in 2012 to 19.71/100 000 (χ(2)=7.90,P=0.005) in 2013 and that of precancerous lesions rose from 106.85/100 000 to 119.26/100 000 (χ(2)=70.82,P<0.001). The early detection rate was 89.60% (11 883/13 263), and 89.57% (12 609/14 078), respectively in 2012 and 2013. In these two years, the rank of the detection rate of each cervical lesion were CIN1, CIN2, CIN3, invasive carcinoma, adenocarcinoma in situ, and microinvasive carcinoma, from the highest rate to the lowest rate. CONCLUSION: The program has achieved certain screening effect and the screening method has been improved. However, the quality of colposcope and histopathology should be enhanced.
