The incidence and mortality rates from primary hepatocellular carcinoma (HCC) are higher in black Americans compared to whites. The goal of this study was to determine if there are racial disparities in HCC stage at diagnosis and treatment.
We compared patient age, tumor stage, rates of surgical intervention and survival in black (n=1718) and white (n=9752) HCC cases between 1992 and 2001 in the Surveillance, Epidemiology and End Results (SEER)-11 + Alaska database.
Black HCC cases were significantly younger at diagnosis (p < 0.0001). Black cases were more likely to have regional and distant metastasis at presentation (p < 0.0005) and were less likely to have surgery performed (p < 0.001). The racial difference in surgery treatment was significant among patients with localized (p = 0.001) and regional (p = 0.012) HCC, but not with distant HCC. Overall survival rates were lower in blacks (p = 0.0033). Survival was similar in blacks and whites with regional and distant disease. Yet, among patients with localized HCC, survival rates were lower in blacks (p = 0.0030).
Black HCC patients have more advanced tumor stage at diagnosis and lower rates of both surgical intervention and survival. The racial disparities in surgical treatment utilization and survival were most striking between black and white HCC patients with localized HCC.
与白人相比,美国黑人原发性肝细胞癌(HCC)的发病率和死亡率更高。本研究的目的是确定在HCC诊断和治疗阶段是否存在种族差异。
我们在监测、流行病学和最终结果(SEER)-11 +阿拉斯加数据库中比较了1992年至2001年间黑人(n = 1718)和白人(n = 9752)HCC病例的患者年龄、肿瘤分期、手术干预率和生存率。
黑人HCC病例诊断时明显更年轻(p < 0.0001)。黑人病例在就诊时更有可能出现区域和远处转移(p < 0.0005),且进行手术的可能性较小(p < 0.001)。手术治疗的种族差异在局限性(p = 0.001)和区域性(p = 0.012)HCC患者中显著,但在远处HCC患者中不显著。黑人的总体生存率较低(p = 0.0033)。患有区域和远处疾病的黑人和白人的生存率相似。然而,在局限性HCC患者中,黑人的生存率较低(p = 0.0030)。
黑人HCC患者在诊断时肿瘤分期更晚,手术干预率和生存率更低。在局限性HCC的黑人和白人HCC患者之间,手术治疗利用率和生存率的种族差异最为显著。
