Summary
A new dynamic nomogram accurately predicts bone metastasis risk in thyroid cancer (TC) patients using age, hemoglobin (HB), and alkaline phosphatase (ALP) levels. This tool aids physicians in clinical decision-making for TC management.
Area of Science:
- Oncology
- Medical Statistics
Background:
- Thyroid cancer (TC) poses a significant risk for bone metastasis.
- Accurate prediction of bone metastasis is crucial for timely clinical intervention and improved patient outcomes.
Purpose of the Study:
- To develop and validate a dynamic nomogram for assessing bone metastasis risk in thyroid cancer patients.
- To provide physicians with a tool for enhanced clinical decision-making regarding TC management.
Main Methods:
- Retrospective analysis of clinical data from 565 thyroid cancer patients.
- Logistic regression analysis to identify predictive factors for bone metastasis.
- Nomogram construction and validation using C-index, ROC curves, calibration plots, and decision curve analysis.
Main Results:
- Bone metastasis was observed in 4.21% of patients.
- Age, hemoglobin (HB), and alkaline phosphatase (ALP) were significant predictors.
- The nomogram demonstrated good discrimination (C-index=0.825) and calibration, with clinical utility at a 1% threshold.
Conclusions:
- A dynamic nomogram incorporating age, HB, and ALP offers a reliable method for predicting bone metastasis risk in TC patients.
- The nomogram facilitates convenient and accurate risk assessment, supporting clinical decision-making.
