RESUMEN
To examine whether the endometrial cancer (EC) survival disadvantage among Black populations is US-specific, a comparison between African descent populations from different countries with a high development index is warranted. We analyzed 28,213 EC cases from cancer registries in Florida (2005-2018) and Martinique (2005-2018)/Guadeloupe (2008-2018), French Caribbean islands. Kaplan-Meier and all-cause Cox proportional hazards models were used to compare survival. Models were stratified by EC histology type and the main predictor examined was race/ethnicity [non-Hispanic White (NHW) and Black (NHB) women in the US versus Black women residing in the Caribbean]. For endometrioid and non-endometrioid EC, after adjusting for age, histology, stage at diagnosis, receipt of surgery, period of diagnosis, and poverty level, US NHB women and Caribbean Blacks had a higher risk of death relative to US NHWs. There was no difference between US NHBs and Caribbean Blacks (HR 1.07, 95% CI: 0.88-1.30) with endometrioid EC. However, Caribbean Black women with non-endometrioid carcinomas had a 40% (HR 1.40, 95% CI: 1.13-1.74) higher risk of death than US NHBs. The low EC survival among US Black women extends to foreign populations of African descent. For the aggressive non-endometrioid ECs, survival in Caribbean Blacks outside of the US is considerably worse.
RESUMEN
BACKGROUND: Endometrial cancer (EC) is the fourth most common cancer among Black women in the United States, a population disproportionately affected by aggressive nonendometrioid subtypes (e.g., serous, carcinosarcoma). To examine EC vulnerability among a wider spectrum of African descent populations, a comparison between Black women residing in different countries, rather than in the United States alone, is needed. METHODS: The authors analyzed 34,789 EC cases from Florida (FL) (2005-2018), Martinique (2005-2018), and Guadeloupe (2008-2018) based on cancer registry data. Age-adjusted incidence rates, incidence rate ratios (IRRs), and annual percent changes (APC) in trends were estimated for Black populations residing in the United States (non-Hispanic Blacks [NHB]) and Caribbean. The US non-Hispanic White (NHW) population was used as a reference. RESULTS: Caribbean Black women had the lowest rates for endometrioid and nonendometrioid subtypes. Nonendometrioid types were most common among US (FL) NHBs (9.2 per 100,000), 2.6 times greater than NHWs (IRR, 2.60; 95% confidence interval [CI], 2.44-2.76). For endometrioid EC, rates increased 1.8% (95% CI, 0.1-3.5) yearly from 2005 to 2018 for US (FL) NHBs and 1.2% (95% CI, 0.9-1.6) for US (FL) NHWs whereas no change was observed for Caribbean Blacks. For nonendometroid carcinomas, rates increased 5.6% (95% CI, 4.0-7.2) among US (FL) NHB, 4.4% (95% CI, 0.3-8.6) for Caribbean Black, and 3.9% for US (FL) NHW women (95% CI, 2.4-5.5). CONCLUSIONS: Lower rates of nonendometrioid EC among Caribbean Black women suggest that vulnerability for these aggressive tumor subtypes may not currently be an overarching African ancestry disparity. Most importantly, there is an alarmingly increasing trend in nonendometrioid across all populations studied, which warrants further surveillance and etiological research for this particular subtype. PLAIN LANGUAGE SUMMARY: We analyze population-based incidence rates and trends of endometrial cancer (EC) for African descent populations residing in different countries (i.e., United States, Martinique, Guadeloupe) to examine whether EC vulnerability among Black women is socio-environmental or more ancestry-specific in nature. The increased EC risk was not uniform across all Black women since the Caribbean had the lowest rates (for endometrioid and nonendometrioid histology subtypes). Regardless, from 2005 to 2018, there was an increasing trajectory of nonendometrioid EC for all groups, regardless of race.

OBJECTIVES: Data from population-based cancer registries contribute to improving our knowledge of digestive cancer trends worldwide. In this study, we present cancer incidence and mortality in Guadeloupe, French Guiana and Martinique for the periods 2008-2014, 2010-2014 and 2007-2014, respectively. DESIGN: Data were extracted from population-based cancer registries. World-standardised incidence (WSI) and mortality (WSM) rates were calculated. Main digestive cancers were analysed, including oesophagus, stomach, colorectum, liver and pancreas cancers. SETTING: This study was performed based on data from French Territories in the Caribbean. RESULTS: We observed a lower-incidence compared with mainland France, except for stomach cancer for which the incidence is high, with significant standardised incidence ratios in men and women at 1.90 vs 2.29 for Guadeloupe and French Guiana and 1.58 vs 2.31 for Martinique. We found a lower-mortality, except for stomach cancer for which the mortality remains high, with significant mortality ratios in men and women at 2.10 vs 2.74 for Guadeloupe, 1.64 vs 1.79 for French Guiana and 2.05 vs 2.53 for Martinique. Overall, these three regions have similar WSI and WSM rates which remain lower than those in mainland France. We noticed an overall high incidence and high mortality in men compared with women as in France. CONCLUSIONS: There is a high incidence of stomach cancer in French overseas territories. Publication of these data contributed to expanding knowledge on the epidemiology of world cancers with data from the Caribbean zone.

PURPOSE: Prostate cancer is the most common cancer in the Caribbean. We present world-standardized incidence (WSI) and mortality (WSM) rates for urological cancers for French overseas territories. MATERIALS AND METHODS: Standardized incidence ratio (SIR) and standardized mortality ratio (SMR) were calculated for 2008-2014, 2007-2014 and 2010-2014 in Guadeloupe, Martinique and French Guiana. RESULTS: For prostate cancer, in Guadeloupe and Martinique, the WSI rates are among the highest in the world (173.0 and 164.5 per 100,000 person-years) and 94.4 in French Guiana. Mortality remains more than twice that observed in mainland France, at 23.0 in Guadeloupe and Martinique, and 16.9 in French Guiana. For bladder cancer, WSI rates were 5.9, 4.9 and 4.1 in men, and 1.9, 1.4 and 1.3 in women, in French Guiana, Guadeloupe and Martinique. WSM rates from bladder varied from 1.5 in French Guiana to 1.8 in Guadeloupe and 2.0 in Martinique in men. In women, it ranges from 0.2 in French Guiana to 0.5 in Guadeloupe and 1.1 in Martinique. Regarding kidney, WSI rates in men are 4.3 in Martinique, 5.2 in Guadeloupe and 6.1 in French Guiana, and 2.3, 2.5 and 3.4, respectively, in women. Mortality rates in men were 1.7 in Guadeloupe, 1.4 in Martinique, and 1.5 in French Guiana, while in women, rates were 0.8 in Guadeloupe and Martinique and 0.6 in French Guiana. All these rates are lower than in mainland France. CONCLUSIONS: Identifying the profile of patients with urological cancers is key to understanding the needs of patients in these regions.

BACKGROUND: Africa and the Caribbean are projected to have greater increases in Head and neck cancer (HNC) burden in comparison to North America and Europe. The knowledge needed to reinforce prevention in these populations is limited. We compared for the first time, incidence rates of HNC in black populations from African, the Caribbean and USA. METHODS: Annual age-standardized incidence rates (IR) and 95% confidence intervals (95%CI) per 100,000 were calculated for 2013-2015 using population-based cancer registry data for 14,911 HNC cases from the Caribbean (Barbados, Guadeloupe, Trinidad & Tobago, Nâ¯=â¯443), Africa (Kenya, Nigeria, Nâ¯=â¯772) and the United States (SEER, Florida, Nâ¯=â¯13,696). We compared rates by sub-sites and sex among countries using data from registries with high quality and completeness. RESULTS: In 2013-2015, compared to other countries, HNC incidence was highest among SEER states (IR: 18.2, 95%CIâ¯=â¯17.6-18.8) among men, and highest in Kenya (IR: 7.5, 95%CIâ¯=â¯6.3-8.7) among women. Nasopharyngeal cancer IR was higher in Kenya for men (IR: 3.1, 95%CIâ¯=â¯2.5-3.7) and women (IR: 1.5, 95%CIâ¯=â¯1.0-1.9). Female oral cavity cancer was also notably higher in Kenya (IRâ¯=â¯3.9, 95%CIâ¯=â¯3.0-4.9). Blacks from SEER states had higher incidence of laryngeal cancer (IR: 5.5, 95%CIâ¯=â¯5.2-5.8) compared to other countries and even Florida blacks (IR: 4.4, 95%CIâ¯=â¯3.9-5.0). CONCLUSION: We found heterogeneity in IRs for HNC among these diverse black populations; notably, Kenya which had distinctively higher incidence of nasopharyngeal and female oral cavity cancer. Targeted etiological investigations are warranted considering the low consumption of tobacco and alcohol among Kenyan women. Overall, our findings suggest that behavioral and environmental factors are more important determinants of HNC than race.

BACKGROUND: Cervical cancer is the fourth cancer worldwide. The Human Papilloma Virus is responsible for 99% of the cases but the distribution of its genotypes varies among populations. We aimed to identify HPV genotypes distribution in women with grade 2/3 cervical intraepithelial dysplasia or invasive cervical cancer in Guadeloupe, a French Caribbean territory with a population mainly of African descent. METHODS: We used paraffin-embedded tumors for viral DNA extraction from women diagnosed between 2014 and 2016 and identified by the population-based cancer registry. The HPV Genotyping was performed with the InnoLIPA HPV Genotyping Extra kit®. RESULTS: Overall, 213 samples out of the 321 eligible records were analyzed. The HPV status was positive for 94% of the cases. The five most common oncogenic HPV genotypes were HPV31 (47%), HPV33 (38%), HPV16 (32%), HPV44 (31%) and HPV26 (28%). HPV18 was found in only in 5% of the cases. Among the studied cases, 94% had multiple infections. More than 60% of single infections were HPV16-related, accounting for 35% of HPV16 infections. CONCLUSIONS: These results show a different distribution of oncogenic HPVs in Guadeloupe with "31 > 33 > 16" and a high frequency of multiple infections. Despite a lower coverage, the nine-valent vaccine is nevertheless adequate.

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.

End stage renal disease is a major public health problem in the French Departments of Guadeloupe and Guiana because of the high prevalence of both type 2 diabetes and hypertension. We investigated factors associated with an emergency start of dialysis, 3 months' quality of life for patients starting a first replacement therapy in Guadeloupe and French Guiana using the data of the Réseau épidémiologie et information en néphrologie network, completed with data from the quality of life questionnaires SF-36 and KDQoL. A total of 242 patients (184 in Guadeloupe and 58 in Guiana) were included. An emergency start was found for 112 (46.5%) patients (Guiana: 74.1%; Guadeloupe: 37.7%). In the multivariate model, an emergency start was associated with the number of nephrology consultations in the year before dialysis and the creation of an arteriovenous fistula prior to the first dialysis. The quality of life scores did not differ between the groups emergency start or not but were higher than those measured in mainland French studies on dialyzed population. Lack of nephrology consultations and dialysis preparation are the main factors associated with an emergency start of the first dialysis, highlighting the need to adapt the provision of care for chronic kidney disease in these departments.
