Socio-demographic predictors of delayed- versus early-stage cervical cancer in California
Menée à partir des données 1996-2005 du registre des cancers de Californie portant sur 13 624 patientes atteintes d'un cancer du col de l'utérus, cette étude identifie les facteurs socio-démographiques associés au risque de détection d'un cancer du col de l'utérus de stade avancé
Purpose : We sought to evaluate and distinguish roles of socio-demographic predictors for delayed- versus early-stage cervical cancer. Methods : Demographic variables for 13,624 cervical cancers having complete data for age at diagnosis (4 categories), race/ethnicity (4 categories), socioeconomic status (SES) quintiles and marital status (3 categories) were extracted from the California Cancer Registry database for 1996–2005 and analyzed using multiple logistic regression as predictors of delayed- versus early-stage diagnosis. Results : Fifty-eight percent of cervical cancers were among women younger than age 50 years, compared to 46 percent of delayed-stage cases. Independent odds of delayed- versus early-stage cervical cancer were higher for older age categories within each race/ethnic group. Declining odds of delayed- versus early-stage diagnosis were evident for increasing SES quintiles among Asian/Other (Trend p=0.015), non-Hispanic Black (p=0.024), Hispanic (p=0.001) and non-Hispanic White (p=0.001) women. Odds of delayed versus early stage cervical cancer were highest among unmarried compared to married women. Conclusions : Our findings support evidence that older age, low SES and unmarried status predict delayed-stage cervical cancer diagnosis in each of the four major race/ethic groups. The two lowest SES quintiles independently identified larger percentages of delayed-stage cervical cancers than race/ethnicity alone, particularly among Hispanic and non-Hispanic Black women.
