We performed a retrospective analysis of DLBCL with breast involvement to compare the prognosis of primary breast lymphoma (PBL) to secondary breast lymphoma (SBL; especially in limited stage cases). We retrospectively reviewed records of 25 diffuse large B-cell lymphoma (DLBCL) patients with breast involvement who received chemotherapy between January 2000 and August 2012. We compared clinical features and prognosis among patients with PBL ( = 11), limited stage SBL (LSBL; = 6), and advanced stage SBL (ASBL, = 8). The PBL group had significantly lesser patients with breast tumours (BTs) > 5 cm than the SBL group ( = 0.02). After a median follow-up of 71.3 months, we observed significantly better 5-year overall survival (OS) in the PBL group (90.0%) than in the LSBL (33.3%, = 0.01) group, but not for progression-free survival (PFS). Patients with BT > 5 cm had worse OS ( = 0.01) and PFS ( = 0.04) than those with BT ≤ 5 cm. PBL had a better prognosis than SBL among limited stage DLBCL.
我们对累及乳腺的弥漫性大B细胞淋巴瘤（DLBCL）进行了回顾性分析，以比较原发性乳腺淋巴瘤（PBL）与继发性乳腺淋巴瘤（SBL；尤其是局限期病例）的预后。我们回顾性分析了2000年1月至2012年8月期间接受化疗的25例累及乳腺的弥漫性大B细胞淋巴瘤（DLBCL）患者的记录。我们比较了原发性乳腺淋巴瘤（PBL，n = 11）、局限期继发性乳腺淋巴瘤（LSBL，n = 6）和晚期继发性乳腺淋巴瘤（ASBL，n = 8）患者的临床特征和预后。与继发性乳腺淋巴瘤组相比，原发性乳腺淋巴瘤组中乳腺肿瘤（BT）>5 cm的患者明显更少（P = 0.02）。中位随访71.3个月后，我们观察到原发性乳腺淋巴瘤组的5年总生存率（OS）（90.0%）明显优于局限期继发性乳腺淋巴瘤组（33.3%，P = 0.01），但无进展生存期（PFS）并非如此。乳腺肿瘤>5 cm的患者的总生存率（P = 0.01）和无进展生存期（PFS，P = 0.04）均比乳腺肿瘤≤5 cm的患者差。在局限期DLBCL中，原发性乳腺淋巴瘤的预后优于继发性乳腺淋巴瘤。
