Testicular tumors are uncommon in black compared to white patients but several reports have indicated that this disease is more lethal in black patients. We reviewed the records of 840 post-puberal patients with primary tumors of the testis seen between 1949 and 1979. There were 17 black and 823 white patients. The predominant tumor in both groups of patients was seminmona. Ten black (58.5 per cent) and 329 white patients (29 per cent) had a non-seminomatous germ cell testicular tumor, while 494 white patients (60 per cent) had such a tumor. These observations alone suggest an over-all better prognosis in black than in white patients. The data demonstrate again the rarity of this disease black patients but our survey shows that black patients with testicular tumors have a better prognosis than has been reported previously.
与白人患者相比，睾丸肿瘤在黑人患者中并不常见，但有几份报告表明，这种疾病在黑人患者中更具致命性。我们回顾了1949年至1979年间840例青春期后原发性睾丸肿瘤患者的记录。其中有17名黑人患者和823名白人患者。两组患者中最主要的肿瘤都是精原细胞瘤。10名黑人患者（58.5%）和329名白人患者（29%）患有非精原细胞瘤性生殖细胞睾丸肿瘤，而494名白人患者（60%）患有此类肿瘤。仅这些观察结果就表明黑人患者的总体预后比白人患者好。数据再次证明了这种疾病在黑人患者中的罕见性，但我们的调查显示，患有睾丸肿瘤的黑人患者的预后比之前报道的要好。
