title: Profile of women 45 years of age and younger with endometrial cancer.
abstract: OBJECTIVE
  The clinical characteristics and outcomes of endometrial cancer patients 45 years of age and younger were compared with those of patients older than 45 years of age.
  
  
  METHODS
  We performed a cross-sectional study of 301 consecutive endometrial cancer patients referred to our center from 1989 to 1994. Of the 289 patients eligible for study, 40 were 45 years of age or younger (group A) and 249 were older than 45 years of age (group B).
  
  
  RESULTS
  The majority of patients in both groups presented with stage I disease. Of the women with stage I disease, patients in group A were more likely than those in group B to have low-grade disease localized to the endometrium (P < .001; relative prevalence 3.39; confidence interval [CI] 1.88, 6.12). However, the distribution of stages I to IV overall was the same for the two groups (P = .269). Although univariate analysis revealed that 11% of the patients in group A and 2% in group B had synchronous ovarian malignancies (P = .007; relative prevalence 5.42; CI 1.39, 21.14), multivariate logistic regression found that nulliparity, not age, was an independent risk factor for synchronous ovarian malignancy (P = .017; relative prevalence 6.15; CI 1.52, 25.61). There were no statistically significant differences by age in the prevalence of high-risk endometrial histology (serous and clear cell carcinoma) or in survival.
  
  
  CONCLUSIONS
  The overall distribution of tumor stage and survival were the same for the younger and older women; this finding contradicts previous reports that suggest that young women with endometrial cancer are at lower risk. Additionally, nulliparity, which occurs with a higher prevalence in younger women who develop endometrial cancer, is associated statistically with the development of synchronous ovarian malignancies.
