Does increased expression of vascular endothelial growth factor C in papillary thyroid carcinoma correlate with cervical lymph node metastases?
The VEGF-C immunoreactive protein is overexpressed in PTC lesions, which correlates with lymph node metastases. VEGF-C expression may play a role in lymphangiogenesis of PTC and further study is necessary to evaluate the clinical application of VEGF-C as a molecular marker for tumor metastases to cervical lymph nodes.
Overall physical health status and asthma-specific quality of life predict subsequent ED utilization. Health-related quality of life may be useful in identifying patients at increased risk for asthma exacerbation requiring emergency care.
