J Rheumatol:儿童期起病系统性红斑狼疮患者中的恶性肿瘤发病率

2017-08-07 xiangting MedSci原创

虽然癌症仍然是儿童期起病的SLE相对罕见的结局,但这项研究数据确实表明在平均随访7.6年间癌症患者的增加。

这项研究旨在分析一个大型儿童起病系统性红斑狼疮(SLE)人群中的癌症发病率情况。

从北美12个儿童SLE登记处获得数据。患者与其所属区域的癌症登记处相关联,以识别入组后的新发癌症,定义为诊所首次诊断的日期。通过将地理位置匹配的年龄、性别和日期年特定的癌症率乘以队列中的人年(从入组到随访结束),获得预期的恶性肿瘤数。产生标准化发病率(SIR,观察到的癌症与预期的比值)和95%CI。

从登记处确定了1168例患者。入组时的平均年龄为13岁(SD 3.3),83.7%为女性。平均随访时间为7.6年,总观察时间为8839年,从1974至2009年。在随访期间,出现14例侵袭性癌症(每1000人年1例1.6例癌症,SIR 4.13,95%CI 2.26-6.93)。其中3个是血液肿瘤(全部为淋巴瘤),导致血液癌的SIR为4.68(95%CI为0.96-13.67)。男性和女性患者年龄组间SIR均升高。

虽然癌症仍然是儿童期起病的SLE相对罕见的结局,但这项研究数据确实表明在平均随访7.6年间癌症患者的增加。约五分之一的癌症是血液方面的。未来需要更长时间随访和关于药物作用和疾病活动的研究。
