Abstract:
BACKGROUND AND OBJECTIVES: We analyzed the clinicopathologic differences of thyroid cancer by diagnosis periods, diagnostic motives, residence history and clinical risk factors in thyroid cancer patients. MATERIALS AND METHODS: Total 1599 thyroid cancer patients who answered the questionnaires about family history of thyroid cancer, residence history including duration of residence and location were enrolled from two hospitals, Seoul National University Hospital and National Cancer Center in Korea. Demographics and environmental information were collected via questionnaires and clinical data were reviewed via electronic medical records. RESULTS: More thyroid cancer has been diagnosed in 2011 to 2013 by screening test without specific symptom than before 1990. The size of cancer at diagnosis was significantly smaller and multifocal tumor was more frequently found in 2011 to 2013 than before 1990 as well. The tumors of obese or overweight patients tended to harbor extrathyroidal extension and lymph node metastasis than normal weight subjects with statistical significance. However, there were no differences in clinicopathologic characteristics according to residence and smoking history. CONCLUSION: In this study, there were some different clinicopathologic characteristics according to the diagnosis era, diagnostic motives, family history of thyroid cancer and body mass index.
