Area of Science:

  • Oncology
  • Surgical Oncology
  • Diagnostic Tools

Background:

  • Detecting central lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC) is challenging.
  • Accurate prediction of CLNM is crucial for effective treatment planning in PTC patients.

Purpose of the Study:

  • To develop and validate a predictive nomogram for CLNM in PTC.
  • To provide clinicians with a tool for quantifying CLNM risk.

Main Methods:

  • A large cohort of 10,763 PTC patients undergoing total thyroidectomy and central neck dissection (CND) was used.
  • Patients were divided into training (n=7,535), internal validation (n=3,228), and external validation (n=2,514) sets.
  • A nomogram was designed based on clinicopathological factors to predict CLNM.

Main Results:

  • The nomogram demonstrated good predictive performance.
  • Area under the receiver operating characteristic curve (AUC) values were 0.721 (training), 0.706 (internal validation), and 0.706 (external validation).
  • These results indicate the nomogram's reliability across different patient cohorts.

Conclusions:

  • The developed nomogram effectively predicts CLNM in PTC patients.
  • It enables personalized risk assessment for both pre- and postoperative periods.
  • Clinicians can utilize the nomogram to guide decisions on prophylactic CND and postoperative surveillance.
