Objective. The aim of this study was to evaluate patterns of care for women with Stage 1A1 and 1A2 cervical cancer utilizing the SEER database. Methods. Review of SEER data from 11 registries from 1990 to 1995 was performed. Data from 2358 women were reviewed and stratified by substage, ethnicity, type of therapy, and age. Results. Three remarkable differences among subgroups were identified. (1) Among women ≥35 years of age, whites were more likely to have Stage 1A1 cancer than blacks or Hispanics; OR (95% CI) = 1.56 (1.05, 2.31) and 1.41 (1.04, 1.91), respectively. (2) Patients ≥35 years of age were more likely to undergo hysterectomy than younger patients both for 1A1 and 1A2 stages; OR (95% CI) = 2.31 (1.68, 3.19) and 2.78 (2.21, 3.50), respectively, with Mantel–Haenszel test of independence χ2 = 102.9943, P value < 0.001. (3) Black and Hispanic women ≥35 years of age with 1A2 disease were less likely to have a hysterectomy than whites. Only 15% of Hispanic patients and 9% of blacks over the age of 35 and with Stage 1A2 were treated via hysterectomy, compared to 76% of white women. Differences in hysterectomies for
