Influencing Factors and Prediction Model of False-negative Central Lymph Nodes in Thyroid Cancer Patients
Influencing Factors and Prediction Model of False-negative Central Lymph Nodes in Thyroid Cancer Patients: a Cohort Study
Source: ClinicalTrials.gov · Last updated 23 May 2024
Brief summary (registry, in English)
The problem of false-negative lymph nodes in the central region (CLN) refers to the inability to detect lymph nodes (LN) metastasis during preoperative ultrasound examination but is confirmed by surgical and postoperative pathological examination. According to this study, the false-negative rate of CLN of patients with TC was relatively high at approximately 71.7%. The high proportion of false-negatives indicates limitations in the sensitivity of ultrasound examination, especially for detecting small LN or small metastases. The presence of false-negative CLN directly affects clinical practice. First, it may lead to insufficient selection of treatment strategies for patients with TC, thereby affecting their prognosis. Second, such false-negative results may lead surgeons to overly trust ultrasound examination during preoperative evaluation, neglecting the importance of comprehensive clinical information, and thus affecting the formulation of treatment plans. This study aimed to explore the factors influencing false-negative CLN through a cohort study and to establish a predictive model.
