Analysis of Body Mass Index and Clinicopathological Factors in Patients with Papillary Thyroid Carcinoma.

OBJECTIVE

To analyze the correlation between body mass index (BMI) and clinicopathological factors of papillary thyroid cancer (PTC).

METHODS

The clinical data of patients with PCT who were hospitalized in the Department of Thyroid Surgery of the Affiliated Hospital of Guizhou Medical University from March 2023 to September 2023 were retrospectively collected, including age, gender, height, weight, BMI, v-raf murine sarcoma viral oncogene homolog B () gene mutation, tumor size, multifocus, Hashimoto's thyroiditis, lymph node metastasis and other clinicopathological factors. According to the World Health Organization (WHO) definition for Asian population, BMI≥25kg/m was obese group, 23≤BMI≤24.9kg/m was overweight group, 18.5≤BMI≤22.9kg/m was normal weight group, and BMI≤18.5kg/m was low weight group. The clinicopathological factors of overweight and obese patients with PTC were analyzed.

RESULTS

A total of 164 PTC patients were included, with an average BMI of (24.44±3.57) kg/m. Age of overweight and obese PTC patients (=1.978, =0.083); Gender of overweight and obese PTC patients ( value: 11.570, =0.004); Tumor size in overweight and obese PTC patients (=0.894, =0.411); gene mutation in overweight and obese PTC patients ( value: 1.452, =0.623); Multifocal lesions were found in overweight and obese patients ( value: 1.653, =0.201). Hashimoto's thyroiditis was found in overweight and obese PTC patients ( value: 1.147, =0.298). Overweight and obese patients with PTC had lymph node metastasis ( value: 1.690, =0.251).

CONCLUSION

Overweight and obesity in PTC patients are correlated with male, but not with age, tumor size, mutation, multifocality, Hashimoto's thyroiditis and lymph node metastasis.
