Trends in Uterine Cervical Cancer Screening at Physical Health Checkups for Company Employees in Japan.

The consultation rate for uterine cervical cancer screening in Japan is markedly low in comparison with other developed countries. The purpose of this study is to investigate the trends in uterine cervical cancer screening during regular company checkups and to identify potential problems. Questionnaires were sent to occupational health physicians through Sansuiken (Alumni Association of the University of Occupational and Environmental Health, Japan). Overall, 127 valid responses showed that Papanicolaou (Pap) tests are conducted in 100 companies (79%). The detailed information from 50 of the 100 responses was analyzed. Mandatory cervical cancer screenings are performed at just 6 companies (12%). Pap test are started at 30 years of age at 9 of 49 companies, and only 18 of 49 companies (37%) start Pap tests for employees at 20 years old. Of the 86,695 women, 31,294 (36%) received cervical cancer screening. Abnormal Pap test results were detected in 3.0%. Although cervical cancer screening rates have slightly increased compared to our previous studies (17% in 2004, 23% in 2008), it remains at a low level. Complete examinations with colposcopy and punch biopsy were carried out in 70% (61 of 87 women) of those with an abnormal Pap test. Twelve of 26 companies had no information about detailed examination results. It is important to note that cervical cancer incidence and mortality are increasing among young women in Japan. Occupational physicians and health nurses should manage female health education and care at the workplace, by including uterine cervical cancer screening in the growing female working population.
