[Clinical and pathologic analysis of 2684 cases of papillary thyroid carcinoma in 8 years]

Objective:To study the clinicopathological and annual features of PTC patients in the past 8 years. Method: Review the clinicopathological data of PTC patients treated by surgery for the first time in the First Affiliated Hospital of Xi'an Jiaotong University from 2010 to 2017. Result: The total number of PTC patients was 2684, which was increasing from 2010 to 2017. The peak age of onset of PTC was 31-60 years old, and the highest peak age was 41-55 years old, including 41-45 years for men and 46-50 years for women. There was no significant difference in the average age of PTC patients during the 8 years(P>0.05). The total male/female ratio oscillated between 1.00：2.91 and there was no significant difference(P>0.05). The increase in the number of male and female patients was approximately parallel. Both had an upward trend(P<0.05). The proportions of multifocal and singletumor cancers were nearly parallel in the 8 years, and there was no significant difference(P>0.05). The percentage of PTC combined with HT increased year by year(P<0.05). The percentage of PTMC showed an increasing trend year by year(P<0.05). The rate of lymph node metastasis in the central area of PTMC was 15.81%. Conclusion: During the past 8 years, the growing number of PTC patients with different genders was approximately parallel. There was no significant difference in the average age and total male/female ratio of PTC patients. The proportions of multifocal and single-tumor cancers were nearly parallel. The percentage of PTC combined with HT has been increasing year by year. The percentage of PTMC showed an increasing trend. .
