Objective:
To evaluate the correlation between ultrasound (US) examination parameters and pathological characteristics of papillary thyroid carcinomas (PTC).
Methods:
A retrospective analysis was conducted using clinical data from 89 patients with PTC (malignant group) and 89 patients with benign thyroid nodules (benign group) who underwent US at Chengdu Shuangliu Hospital of Traditional Chinese Medicine between February 2021 to February 2023. The correlation between ultrasound parameters and pathological features of PTC was analyzed.
Results:
Ultrasound parameters in the malignant group were significantly different from those in the benign group (P<0.05). Peak systolic blood flow velocity (PSV), pulsation index (PI), and resistance index (RI) were significantly higher in patients with malignant lymph node metastasis (LNM) and stage III-IV PTC. In contrast, peak intensity (Peak), mean transit time (MTT), time to peak (TTP), and area under curve (AUC) were significantly lower than those in patients without LNM and stage I-II (P<0.05). Spearman's analysis revealed significant correlations between ultrasound parameters, LNM, disease staging, and gene mutations (P<0.05). Of the 89 PTC patients, 27 had disease recurrence, and five died during the follow-up. The poor prognosis group had significantly higher PSV, PI, and RI and lower Peak, MTT, TTP, and AUC compared to the good prognosis group (P<0.05).
Conclusions:
Ultrasound is a valuable tool for diagnosing and evaluating papillary thyroid carcinoma (PTC). It shows strong correlations between ultrasound parameters and pathological features, including lymph node metastasis and disease staging, aiding early diagnosis and prognosis prediction.
