Gynaecological cancer in Caribbean women: data from the French population-based cancer registries of Martinique, Guadeloupe and French Guiana (2007–2014)

Abstract

Background For the first time, we present regional-level cancer incidence and world-standardized mortality rates for cancers for Martinique, Guadeloupe and French Guiana. Methods For Martinique, Guadeloupe and French Guiana, incidence data come from population-based cancer registries, and cover the periods 2007–2014, 2008–2014 and 2010–2014 respectively. Standardized incidence and mortality rates were calculated using the world population. Results In the 3 regions, all cancers combined represent 3567 new cases per year, of which 39.8% occur in women, and 1517 deaths per year (43.4% in women). Guadeloupe and Martinique present similar world-standardized incidence rates. Among gynaecological cancers, breast cancer, the second most common cancer type in the 3 regions, has an incidence rate 35 to 46% lower than in mainland France. On the other hand, cervical cancer has a higher incidence rate, particularly in French Guiana. For both endometrial cancer and ovarian cancer, no significant differences in incidence rates are found compared to mainland France. Regarding mortality, world-standardized mortality rates are similar between Guadeloupe and Martinique, and higher than in French Guiana. This situation compares favourably with mainland France (all cancers). Among gynaecological cancers, the mortality rate is lower for breast cancer in all regions compared to mainland France, and also lower for ovarian cancer in Martinique and Guadeloupe, but higher (albeit non-significantly) in French Guiana. Conclusion The ethno-geographic and socio-demographic characteristics in this population of mainly Afro-Caribbean origin could partially explain these disparities. Major disparities exist for certain cancer sites: excess incidence and excess mortality for cervical cancer; lower, but increasing incidence of breast cancer.

Pathological Significance of GLUT-1 Expression in Breast Cancer Cells in Diabetic and Obese Patients: The French Guiana Study

“…The Department of Pathology of Cayenne Hospital Center is the only specialist laboratory in French Guiana, which analyses the majority of samples from the city of Cayenne and adjacent towns, as well as from the isolated communes’ health centers known as CDPS (Centres Délocalisés de Prévention et de Soins). Nevertheless, between 2014 and 2020, we had only 199 patients with invasive breast cancer, which is lower than the reported incidence in French Guiana [ 33 ]. In fact, some analyses from hospitals of Kourou and West Guiana in Saint Laurent du Maroni are sent to laboratories in mainland France, resulting in a false lower incidence in our study for these two cities.…”

The Repository for Caribbean Cancer Publications (ReCCaP): Database Development and Publication Trends 2004–2019

“…Martinique demonstrates its focus on cancer research through robust data collection through the Martinique Cancer Registry and publication of results. [16][17][18] Of note, Jamaica -an upper-middle-income country of 2.95M people and three universities -has the third highest PR overall 5438 but has experienced a steady decline since 2012. In 2012, Jamaica experienced negative economic growth (−0.30%), with their goods and service sector declining or showing no growth.…”

Gemcitabine cationic polymeric nanoparticles against ovarian cancer: formulation, characterization, and targeted drug delivery

“…These types of malignancies among women are challenging to treat, and therefore they are very much incurable (Gatenby & Brown, 2020 ; Shen et al., 2020 ; Annaji et al., 2021 ). It is the second most common gynecological cancer in females, with a registered incidence of about 15 cases per 100,000 women in western countries(Joachim et al., 2020 ). Early menopause, heavy consumption of saturated fats and refined carbohydrates intensively increase the risk of ovarian cancer (Cazzaniga et al., 2021 ).…”
