Prostate cancer is the most common male cancer in industrialized countries, including France, with over 60,000 new cases each year, and represents the third leading cause of cancer-related death in men. The only known risk factors are age, ethnic origin and family history of prostate cancer. Indeed, there are considerable ethnic disparities in prostate cancer risk, with an incidence rate 60% higher in African-American men than in European-American men (Evans 2008). Similarly, in the French West Indies, where over 90% of the population is of Afro-Caribbean origin, the incidence of prostate cancer is twice as high as in mainland France. In 2015, the annual incidence was 88.5 cases per 100,000 in mainland France (Defossez 2021), while it was 184.1 cases per 100,000 in Guadeloupe, over the period 2008-2013 (Desloumeaux 2017), and 161.1 cases per 100,000 in Martinique, over the period 2005-2014 (Joachim 2019). The incidence rates observed in the French West Indies are of the same order as those observed in Afro-Caribbean populations in the UK and African-American populations in the USA (Ben Schlomo 2008, Evans 2008). The reasons for these ethnic disparities in incidence are still poorly understood, but the role of genetic factors has been suggested. Indeed, certain genetic polymorphisms have been associated with an increased individual risk of prostate cancer in men of sub-Saharan African origin (Conti 2021; Karunamuni 2021; Marlin 2021). In addition, certain environmental facto…
