摘要
乳腺植入物相关性间变性大细胞淋巴瘤(breast implant-associated anaplastic large cell lymphoma, Bl-ALCL)是一种罕见的、发生在乳腺植入物周边的T细胞淋巴瘤。大多数患者的临床表现为假体周边积液,部分患者也可出现乳腺肿块或发生淋巴结累犯(lymph node involvement, LNI)。本研究的目的是描述BI-ALCL患者淋巴结的病理特征并评估LNI对患者预后的影响。本研究评估了 70例BI-ALCL患者淋巴结的临床表现和组织病理学特征。LNI是指在淋巴结中出现ALCL的组织形态。14例(20%) BI-ALCL患者存在 LNI,均为局部淋巴结,以腋窝淋巴结的发生率最高(93%)13例(92.9%)患者的累犯模式为窦性,通常呈滤泡周、滤泡间和弥漫性分布。2例患者的肿瘤细胞呈霍奇金淋巴瘤样分布。伴有LNI患者的5年总生存率为75%,未发生LNI患者的5年总生存率为97.9% (P= 0.003)。49例肿瘤局限在包 膜内的患者中有6例(12.2%)伴有LNI,与之相比,21例肿 瘤浸润至包膜外的患者中有8例(38%)伴有LNI。大多数发 生LNI患者在接受各种治疗后可得到完全缓解。与56例不伴有LNI患者无死亡率(0/56)相比,14例伴有LNI患者中有 2例(14.3%)死于该病变。20%的BI-ALCL患者存在LNI, 多数呈窦性分布。我们得出结论,BI-ALCL浸润至包膜外的患者发生LNI的风险更高。LNI与患者缩短的总生存率相关。诊断该病需要注意不要误诊为霍奇金淋巴瘤。
