Introduction: Obesity is a serious health problem worldwide, especially in well developed countries. It is a cause of various diseases, including thyroid cancer. The relationship between obesity and prognostic factors of thyroid cancer is uncertain.
Aim of the study: Evaluation of relationship between the body mass index (BMI) and clinicopathological features increasing the risk of poor clinical course, treatment response and clinical outcome in patients with differentiated thyroid cancer (DTC).
Material: The study included 1,181 patients with DTC (88% women and 12% men) who were treated at a single center from 2000 to 2016, who underwent retrospective assessment of BMI and clinicopathological features before surgery. The relationship between clinical features of treatment response (excellent, indeterminate, biochemically incomplete, structurally incomplete) or final status of the disease (remission, persistent disease, death) and BMI was evaluated. Patients were stratified according to BMI (underweight, normal weight, overweight and obesity according to World Health Organization classification). Statistical analysis was performed using univariate and multivariate logistic regression analysis.
Results: Median follow-up was 7.7 years (1–16 years). BMI did not affect the response to treatment or outcome of the disease (remission, persistent disease, death). Obesity was more prevalent in men (P=0.033) and was more common in patients ≥45 years of age (P=0.001). We found statistically significant relationship of advanced TNM stage (III-IV) with increases in BMI (P=0.029), however this association disappeared after adjusting for age of ≥45 years (P=0.832).
Conclusions: Obesity in our study is not associated with more aggressive clinicopathological features of cancer, it is not a risk factor for higher clinical stage of cancer, it is not a prognostic factor for poorer treatment response and clinical outcome in DTC patients.
