Official title
A Multicenter Study on Developing a Multimodal Deep Learning Model Based on Color Doppler Ultrasound for Predicting Lymph Node Metastasis and Cancer Staging in Papillary Thyroid Carcinoma
Overview
Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy in clinical practice, accounting for approximately 85% of all thyroid malignancies. The occurrence of cervical lymph node metastasis further increases the risk of local tumor recurrence and distant metastasis, thereby reducing patient survival rates. Pathological examinations reveal that approximately 30-80% of PTC patients have lymph node metastasis. Early detection of metastatic lymph nodes and the development of individualized treatment plans are crucial for improving patient prognosis. Currently, the primary method for diagnosing lymph node metastasis is ultrasound-guided fine-needle aspiration, but its accuracy is limited by sample quality and carries a risk of false-negative results. In recent years, deep learning technology has demonstrated significant potential in the field of medical image analysis. Therefore, the investigators aim to develop a deep learning model based on neck ultrasound to more accurately predict lymph node metastasis.
Interventions
- Other not intervention
This is a retrospective observational study in which participants will not undergo any interventions, and only data collection and analysis will be performed on the participants.
Primary outcome measures
- Area Under the Receiver Operating Characteristic Curve for a Multimodal Deep Learning Model Based on Cervical Ultrasound in Predicting Lymph Node Metastasis [Time frame: Within 2 months after the completion of subject enrollment]
- Sensitivity of a Multimodal Deep Learning Model Based on Cervical Ultrasound for Predicting Lymph Node Metastasis [Time frame: Within 2 months after the completion of subject enrollment.]
- Specificity of a Multimodal Deep Learning Model Based on Cervical Ultrasound for Predicting Lymph Node Metastasis [Time frame: Within 2 months after the completion of subject enrollment.]
Secondary outcome measures (3)
- The pathologically confirmed lymph node metastasis rate in the study cohort [Time frame: Within 2 months after the completion of subject enrollment]
- Adjusted Odds Ratios for Clinical Factors Associated with Pathologically Confirmed Lymph Node Metastasis [Time frame: Within 2 months after the completion of subject enrollment]
- The weighted Kappa coefficient for the consistency between model-predicted pTNM stage and pathological stage [Time frame: Within 2 months after the completion of subject enrollment]
