Objective: To examine trends and characteristics of single women with malignancy of the uterine cervix.
Methods: This is a retrospective observational study examining the United States population-based tumor registry (the Surveillance, Epidemiology, and End Results program). Time-specific trends in single marital status were examined in 3,294,208 women among 12 common female malignancies including 87,151 women with uterine cervical malignancy between 1973 and 2013.
Results: While the proportion of single women in the majority of malignancies increased during the study time, the proportion of single women with cervical malignancy significantly increased more than in other malignancies (29.3% in 2013 from 6.3% in 1973). There was a surge in the proportion of single women with cervical malignancy starting in the early 1990s, exhibiting the largest annual percentage rate change (APC) among all examined malignancies (1.8%; 95% confidence interval [CI]=1.6, 2.0; p<0.001). There was a significant decrease in the proportion of women aged <40 years with cervical malignancy between 1989 and 2013 (APC, ?1.2%; 95% CI=?1.4, ?1.0; p<0.001). However, when stratified by age, the proportion of single women aged ≥40 years increased significantly during the time (APC, 2.7%; 95% CI=2.3, 3.2; p<0.001) but did not in those who were <40 years (APC, 0.1%; 95% CI=?0.7, 0.6; p=0.850).
Conclusion: The proportion of single women with malignancy of the uterine cervix has significantly increased in the past 4 decades. This increase was most dramatic in single women aged ≥40 years. Improving screening strategies in single women aged ≥40 years may help reduce the incidence of this malignancy.
