Malignant tumours of the testis are reported to be rare in negroes. All cases reported in the records of the University Hospital of the West Indies and the Jamaica Cancer Registry over the period June 1958 to December 1976 were studied. There were 26 cases, giving a world standardised incidence of 0.40 per 100,000 per year. This incidence is higher than that seen in African negroes but lower than that of negroes in North America. The peak age incidence is a decade later than that commonly seen in high incidence countries.
据报道,睾丸恶性肿瘤在黑人中较为罕见。对西印度群岛大学医院记录以及牙买加癌症登记处1958年6月至1976年12月期间报告的所有病例进行了研究。共有26例,每年的世界标准化发病率为每10万人中有0.40例。这一发病率高于非洲黑人,但低于北美的黑人。发病年龄高峰比高发病率国家常见的发病年龄高峰晚十年。
