Background: Thyroid cancer (TC) overall survival at 5 years was estimated at 97% in mainland France over 2010–2015. Its prognosis is known to be affected by patient age, tumor histology, size, and extension. This study aims to describe overall survival of thyroid cancer patients diagnosed between 2008 and 2018 in Martinique. Methods: We included in this retrospective analytical study all patients who were diagnosed with thyroid cancer. An overall survival analysis at 1, 3 and 5 years of thyroid cancer patients diagnosed in Martinique from 2008 to 2018 was conducted. Prognostic factors associated with survival have been identified. Stage at diagnosis and patterns of care among thyroid cancer patients were analyzed. Results: A total of 323 thyroid cancer patients were registered between 2008 and 2018. Papillary carcinomas represented 83% of diagnoses. Local stage or locally advanced invasion was found in 264 (88%) patients. 221 Multidisciplinary Teams reports files were reviewed. The overall survival observed in this population is 97% [93–99] at 1 year, 93% [88–97] at 3 years and 91% [85–95] at 5 years. Anaplastic, poorly differentiated and medullar tumors had lower survival rates at 5 years (39% [13–65]) compared to papillary tumors (93% [89–96]). We found that metastatic stage at diagnosis (HR = 3.1[1.3–7.6]; p = 0.01) and tumor size > 3 cm (HR = 2.7 [1.1–6.3]) were independent prognostic factors for OS in our population. Conclusions: The survival rates of thyroid cancer in Martinique are comparable to those observed in France. [ABSTRACT FROM AUTHOR]
