Predicting Prognosis and Recurrence of Thyroid Cancer Via New Biomarkers, Urinary Exosomal Thyroglobulin and Galectin-3

Rövid összefoglaló (regiszter, angolul)

Although thyroid cancers are low-grade endocrine malignancy, most patients usually received thyroidectomy with ablative radioactive iodine therapy. Such patients were followed with thyroid ultrasonography and serial serum thyroglobulin evaluation. Prior researches indicated that one-third well-differentiated thyroid cancers could transform to poorly-differentiated patterns, even to be anaplastic thyroid cancer (ATC), a fatal malignancy, and no effective therapeutic strategies was noted, including surgical intervention, chemotherapy and radiotherapy. The poorly-differentiated or anaplastic change of thyroid cancer cells proliferates rapidly and always invades local tissues with distant metastasis. Cellular de-differentiation is the most pivotal cause for malignant transformation and invasion. De-differentiation usually in papillary thyroid cancer and follicular thyroid cancer, and definitely in ATC. Therefore, the investigators try to find the biological markers and therapeutic targets via the exosomal expression in urine. On the continuing basis of prior ATC cells culture experiments. Exosomes are nanovesicles secreted into extracellular environments. Cancer cell-derived exosomes could be found in plasma, saliva, urine and other body fluid of patients with cancer. The investigators try to analyze the urinary exosomal proteins, including thyroglobulin and galectin-3, to find the early prognostic biological markers in urine via this prospective study. The investigators expected to enroll 150 post-operative patients with papillary, follicular or anaplastic thyroid cancer, and collect the urine samples in outpatient clinic per year. The investigators will analyze the urine exosomal proteins and probable biological markers, including thyroglobulin and galectin-3. The investigators hope to find the prognostic biological markers via this prospective study. The investigators further hope to find newly therapeutic and follow-up pathway for such patients with well-differentiated or anaplastic thyroid cancer.
