Abstract
Introduction: The most prevalent endocrine malignancy is thyroid carcinoma. Thyroid cancer is much more common than it was previously. The prognosis of people with this condition can be impacted by a number of factors.
Objectives: The purpose of this study was to assess the prognosis and survival rates of thyroid cancer patients in western Iran.
Patients and Methods: This retrospective cohort study was performed on all patients (n = 312) with diagnosing thyroid cancer based on pathology results between 2011 and 2021. Demographic and clinical information and disease staging of patients based on TNM (tumor, node, and metastasis) system were extracted from patients’ medical records. Kaplan-Meier method, log-rank test, and Cox regression were used for the analysis of the data. The obtained data were analyzed in SPSS version 22.
Results: Our findings showed that the mean survival time for all participants in the study was 39.9 months. Additional analysis revealed that the mean survival time is significantly lower in people who residence in urban areas. Furthermore, men, people aged 50-80 years old, and those who were in the TNM stage I had the highest mean survival time. Based on the univariate analysis age, TNM stage are associated with risk of death in patient with thyroid cancer.
Conclusion: Death from thyroid cancer is correlated with patients’ age, gender, and disease stage. Age is important risk of death. Additionally, overall survival of the patients decreases with increasing time.
