An Ultrasonographic Tumor Location-Based Model for Predicting Central Lymph Node Metastasis in Unifocal Papillary Thyroid Microcarcinoma
To create and authenticate a nomogram that combines tumor spatial positioning with clinical and ultrasonographic characteristics to forecast central lymph node metastasis (CLNM) in unifocal papillary thyroid microcarcinoma (PTMC).
Key Findings:
Age ≤ 38 years, tumor size > 0.95 cm, presence of microcalcifications, suspicious central/lateral lymph nodes, tumor located in the isthmus, and tumor situated in the middle/inferior pole adjacent to the posterior capsule are independent risk factors for CLNM.
Hashimoto's thyroiditis is identified as a protective factor against CLNM.
The nomogram achieved AUCs of 0.772 in training and 0.728 in validation.
Interpretation:
The nomogram effectively predicts CLNM risk based on tumor characteristics, aiding in surgical decision-making.
Limitations:
Retrospective nature may introduce selection bias.
External validation is needed to confirm generalizability.
Conclusion:
The nomogram based on spatial location is a valuable preoperative tool for assessing CLNM risk, facilitating tailored surgical planning and reducing overtreatment in unifocal PTMC.
When Alexander Shifrin, MD, reflects on his 20 years as an endocrine surgeon, what stands out most is not the technical complexity of the operations he performs, but the consistency with which he can offer something rare when it comes to cancer care.
