Risk factors in women 40 years of age and younger with endometrial carcinoma.
OBJECTIVE
To identify and compare risk factors among endometrial cancer patients ≤40 years of age, postmenopausal women with the same malignancy and women ≤40 years without malignancy.


METHODS
Retrospective case-control study.


METHODS
Athens University, department of obstetrics and gynecology of a tertiary hospital serving a mainly urban population.


METHODS
Endometrial cancer patients ≤40 years (study group, n = 40), postmenopausal women with the same malignancy (positive controls, n = 40) and women ≤40 (negative controls, n = 40) without endometrial cancer.


METHODS
Clinical history, treatment and follow-up of patients were evaluated. Factors studied included age, histology, stage, grade, lymphovascular space involvement, body mass index (BMI), cytology, lymph node status, parity, smoking, family history, hypertension recurrence and survival.


METHODS
Differences in risk factors and characteristics.


RESULTS
Nulliparity, smoking and hypertension were significantly related with endometrial cancer in the study group compared to positive controls (p = 0.001, p < 0.01 and p < 0.001, respectively). BMI >30 significantly characterized patients in the study group compared to negative controls (p = 0.006). Finally, irregular menstruation and family history of cancer were observed more often in the study group compared to both control groups. Stage, grade, myometrial invasion, lymphovascular space involvement and lymph node status were comparable between the study and positive control groups.


CONCLUSIONS
Nulliparity, obesity, unstable menstruation, smoking and cancer in the family are strongly correlated with endometrial cancer risk in women ≤40 years.
