摘要 目的探讨弥漫大B细胞淋巴瘤(DLBCL)骨髓SHP-1基因启动子甲基化检测的意义。方法收集初治DLBCL患者骨髓标本37例,以正常骨髓标本20例作为对照,采用甲基化特异性PCR方法检测SHP-1基因启动子区域CpG岛甲基化状态,动态监测研究组骨髓细胞形态学、骨髓活检及SHP-1基因甲基化状态,并随访观察。结果 20例正常骨髓SHP-1基因启动子甲基化检测均为非甲基化状态,37例DLBCL患者骨髓11例检出SHP-1基因启动子甲基化,两者甲基化率比较存在统计学差异(P<0.05);比较甲基化组和非甲基化组接受3个疗程CHOP后的缓解率及1 a复发率,Ⅲ/Ⅳ期病例甲基化组缓解率低于非甲基化组,1 a复发率高于非甲基化组(P<0.05);随访期间,共12例患者最终出现骨髓SHP-1基因甲基化,其中4例经骨髓活检证实存在淋巴瘤细胞骨髓浸润,其他25例患者最终未出现骨髓SHP-1基因甲基化,且骨髓活检均未发现淋巴瘤细胞浸润,差异具有统计学意义(P<0.05)。SHP-1基因甲基化与骨髓受累相符率达33.3%。结论 SHP-1基因甲基化检测可能为预测DLBCL患者预后和复发倾向及早期评价DLBCL骨髓受累的有效方法。
