Abstract: Objective To investigate the clinical characteristics of patients with different gender who diagnosed as differentiated thyroid cancers(DTC).Methods A cohort of patients with DTC underwent surgery in Chinese PLA General Hospital from October 2001 to may 2011 was retrospectively studied.Results (1) A total of 1 756 patients with DTC were enrolled in the study and a marked female preponderance was found with the female/male ratio of 2.32∶ 1.The peak incidence was 35-45 years old in both genders.Higher prevalence of DTC was observed in the male patients with a single nodule than in the males with multinodulars (36.42% vs 28.90%,P < 0.01),while no statistical difference was found in the female patients(33.60% vs 31.77%,P > 0.05).(2) Ultrasound examination revealed that,the female DTC patients with microcalcification thyroid nodules were more than the male patients (69.26% vs 62.62%,P <0.05),while less in female patients with undefined boundary thyroid nodules (57.79% vs 72.01%,P < 0.01).The tumor size was shown to be smaller in the women than in the men [(1.6 ± 1.3) cm vs (1.8 ± 1.5) cm,P < 0.01].(3) Higher rates of Ⅲ/Ⅳ TNM Stage,lymph node metastasis and extrathyroidal invasion were found in the men than in the women (21.74% vs 14.51%,P <0.01,33.27% vs 23.80%,P <0.01 and 10.59% vs 7.17%,P < 0.01).Conclusion There is significant gender-related difference of clinical characteristics in the patients with DTC.
