An Observational Study on Postoperative Symptoms After Thyroidectomy (POS-T)

Study Overview
=================
Brief Summary
-----------------
This observational study aimed to evaluate the safety and efficacy of postoperative management in patients with thyroid cancer who received subtotal or total thyroidectomy.

Detailed Description
-----------------
Characteristic analysis of improvement in quality of life and symptoms after surgery in cancer patients Multifaceted symptom evaluation of cancer patients visiting medical institutions Evaluation of effectiveness and safety of treatment for postoperative symptoms in thyroid cancer patients Analysis of the effectiveness and prognosis of cancer-related treatment for each patient with cancer Analysis of prognostic factors for disease-free survival and overall survival of cancer patients Among adult men and women aged 19 years or older who have been diagnosed with thyroid cancer, who have undergone partial or total thyroidectomy and visited the hospital for postoperative management, the characteristics of the visiting patient, quality of life, characteristics of cancer-related symptoms, and treatment effectiveness, We intend to conduct a prospective observational study to evaluate safety and its relationship with prognosis. In addition, we aim to form the basis for follow-up research through the establishment of an Oriental medicine cancer cohort and database.
