Objective : Okinawa Prefecture is one of the regions of Japan with a high incidence of cervical cancer and also a high mortality associated with the disease. We changed the cytological screening procedure from the conventional method to the LBC method and validated the effectiveness of introducing LBC by comparing the two methods.
Study Design : The subjects were 90750 women who had participated in the cervical cancer screening program from 2011 to 2015 in the Okinawa Chubu District of the main island of Okinawa. We examined the unsatisfactory specimen rate, “close examination required” rate and the CIN detection rate in each fiscal year : conventional method in 2011 & 2012, and the LBC method (BD SurePathTM) in 2013 & 2014.
Results : After introduction of the LBC method, the unsatisfactory specimen rate reduced from 0.12% to 0.03% ; furthermore, the “close examination required” rate and detection rate of over CIN1 and CIN2 lesions were twice as high with the LBC method as with the conventional method (p<0.001).
Conclusion : Our findings demonstrated the high effectiveness of introducing the LBC method for cervical cancer screening in Okinawa.
