Overall survival of patients with thyroid cancer in Martinique (2008-2018).

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.

Cancer burden in the Caribbean: an overview of the Martinique Cancer Registry profile.

BACKGROUND: Cancer indicators are essential information for cancer surveillance and cancer research strategy development. The Martinique Cancer Registry (MCR) is a population-based cancer Registry (PBCR) that has been recording cancer data since its creation in 1981. This article provides cancer incidence and mortality data for all cancers and for major tumor sites. METHODS: The registry collects all new cancer cases, details of the individual affected, tumor site and follow-up. World-standardized incidence and mortality rates were calculated, by tumor site and sex for solid tumors from the MCR database for the study period 2001-2015. RESULTS: Over the period 2001-2015, a total of 22,801 new cases were diagnosed; 13,863 in men (60.8%) and 8938 in women (39.2%). In 2011-2015, 1631 new cases were diagnosed per year. Age-standardized (to the world population) incidence rates for all cancers, were 289.8 per 100,000 men and 171.0 per 100,000 women. Breast, colon-rectum and stomach were the most common cancer sites in women. Prostate, colon-rectum and stomach were the main sites in men. Martinique has higher incidence rates of prostate and stomach cancer than mainland France. CONCLUSIONS: Prostate and stomach cancers have high incidence and rank first among the four major tumor sites. Providing data for the French zone of the Caribbean is essential to contributing to the development of high-priority public health measures for the Caribbean zone.
