Abstract:
BACKGROUND: Incidence of thyroid cancer has been rapidly increased, in not only small sizes with improved detection devices but also large size of tumors whose underlying mechanisms remain unclear. Body size and weight change in adulthood were examined as the potential risk factors for thyroid cancer development. METHODS: A large scale case-control study was conducted with constructed questionnaire for their height, weight (current, 2 years ago, at the age of 20 and 35 years old) and confounders. Medical charts were reviewed for cancer histology, tumor aggressiveness and BRAF mutation status. A total of 2,003 cases (1,611 females and 392 males) and individually matched 17,700 controls (13,983 females and 3,717 males) by age, sex, 12-year education and birth year were included. Logistic regression model were used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Having a tall height and heavy weight was associated with increased risk in both females [OR and 95%CI for height and weight: 1.46 (1.25-1.71) and 2.66 (2.24-3.15), respectably] and males [OR and 95%CI for height and weight: 1.71 (1.25-2.34) and 2.80 (2.00-3.92), respectably] compared to those in the lowest quartile for the body sizes. This study observed approximated tripled the risk of thyroid cancer [OR and 95%CI: 3.03 (2.10-4.37)] when female subjects gained 10kg or more within recent 2 years. Males who gained 10 kg or more after 35 years old were more likely to have a greater tumor size [ & lt;1cm vs. ≥1cm: 3.76 (2.62-5.38) vs. 6.87 (4.38-10.77)]. However, other factors were not significantly related to increased tumor aggressiveness (tumor size, lymph node metastasis, and mutlifocality) and BRAF mutation affected carriers. CONCLUSION: The results support plausible hormonal and metabolic factors related height, weight, and rapid weight gain in adulthood increase thyroid carcinogenesis.
