[Analysis of clinical characteristics of 854 patients with thyroid cancer]

Objective:The aim of this study is to summarize and analyze the clinical features of thyroid cancer surgery patients, and provide information and guidance for clinical diagnosis and treatment. Method:The medical records of 854 patients with thyroid cancer who met the inclusion criteria from January 2013 to December 2018 were collected from the hospital's medical record system. Patients were grouped by age group and their stratified studies were performed on age, gender, pathological type, and cervical lymph node metastasis. Result:The total number of patients with thyroid cancer surgery in 2013-2018 showed an increasing trend. There was no significant difference in the age composition of thyroid cancer patients between different years （P>0.05）, but the age of 20-54 years old gradually increased with age, and reached a peak at 50-54 years old, then gradually decreased. There was no significant difference in gender composition between patients with thyroid cancer surgery in 2013-2018 （P>0.05）, but in 40-44 years old, the prevalence of women in the 50-54 age group was higher than that in men （P<0.05）, The prevalence of men in the 70-74 age group was higher than that in women （P<0.05）, and the peak period of both was 50-54 years old. Papillary carcinoma accounted for a high proportion （96.8%） in the pathological types of thyroid cancer surgery patients in 2013-2018, and the incidence of women in the 40-44 age group was higher than that in men（P<0.01）, in the 70-74 age range. The incidence was higher than that of women （P<0.01）. The incidence of follicular carcinoma （1%） was higher in men than in women （P<0.05）. The incidence of lymph node metastasis in women with thyroid cancer was lower than that in men （P<0.05）. Conclusion:The incidence of thyroid cancer in different age groups has its own characteristics, and prevention and control measures should be formulated according to age groups.
