BACKGROUND: For solitary papillary thyroid carcinoma on the isthmic (SPTCI), there are currently no specific guidelines for the extent of resection and lymph node dissection. This study aims to explore the surgical strategies suitable for patients with SPTCI.
METHODS: Firstly, they were divided into the large-scale thyroidectomy (LT) group and the small-scale thyroidectomy (ST) group according to different surgical methods. After balancing the baselines of the two groups using the PSM method, the postoperative complications and recurrence were compared. In addition, a clinical prediction model was constructed with whether central lymph node metastasis (CLNM) occurred as the outcome indicator. The performances of the traditional logistic regression model and four machine learning models were compared, and the optimal model was visualized.
RESULTS: After 1:1 PSM, there was no statistically significant difference in postoperative complications and recurrence rate between the ST group and the LT group (p > 0.05). In addition, CLNM occurred in 65 patients. Finally, the traditional logistic regression model was selected. The area under the curve (AUC) was 0.752, the Youden index was 0.391, the sensitivity was 0.708, and the specificity was 0.683. There are six predictors, including age, BMI, TSH, aspect ratio, calcification and tumor size. The internal verification results show that the prediction model has a high degree of repeatability.
CONCLUSIONS: According to the CLNM risk prediction model we developed, for those SPTCI patients evaluated as high-risk, small-scale thyroidectomy combined with preventive central lymph node dissection may be a feasible alternative approach.
