Bleomycin pulmonary toxicity (BPT) has been well described in Hodgkin's lymphoma (HL) patients treated with bleomycin-containing chemotherapy regimens. The influence of this pulmonary complication, along with the omission of bleomycin from further chemotherapy, on overall survival (OS) and progression-free survival (PFS) in HL remains unclear. We reviewed our experience with BPT in HL to better delineate outcome and appropriate treatment in these patients.
One hundred forty-one patients who were treated with bleomycin-containing chemotherapy for newly diagnosed HL between January 1986 and February 2003 were eligible for this retrospective review. BPT was defined by the presence of pulmonary symptoms, bilateral interstitial infiltrates, and no evidence of an infectious etiology.
BPT was observed in 18% of patients. Increasing age, doxorubicin, bleomycin, vinblastine, and dacarbazine as initial therapy, and granulocyte colony-stimulating factor use were associated with the development of BPT. Patients with BPT had a median 5-year OS rate of 63% v 90% (P = .001) in unaffected patients. The mortality rate from BPT was 4.2% in all patients and 24% in patients who developed the pulmonary syndrome. BPT incidence and mortality were highest in patients older than 40 years. The omission of bleomycin had no impact on obtaining a complete remission, PFS, or OS.
BPT results in a significant decrease in 5-year OS in patients who are treated for HL. Age > or = 40 years seems to add substantially to the risk. In patients who do not die from acute pulmonary toxicity, both OS and PFS seem equal, despite the omission of bleomycin.
博来霉素肺毒性(BPT)在接受含博来霉素化疗方案治疗的霍奇金淋巴瘤(HL)患者中已有详细描述。这种肺部并发症以及后续化疗中不再使用博来霉素对HL患者总生存期(OS)和无进展生存期(PFS)的影响仍不明确。我们回顾了我们在HL患者中处理BPT的经验,以更好地明确这些患者的预后及合适的治疗方法。
1986年1月至2003年2月间,141例接受含博来霉素化疗方案治疗新诊断HL的患者符合此次回顾性研究标准。BPT定义为存在肺部症状、双侧间质浸润且无感染病因证据。
18%的患者出现BPT。年龄增长、初始治疗使用多柔比星、博来霉素、长春碱和达卡巴嗪以及使用粒细胞集落刺激因子与BPT的发生相关。发生BPT的患者5年OS率中位数为63%,而未受影响患者为90%(P = 0.001)。所有患者中BPT的死亡率为4.2%,发生肺部综合征的患者中为24%。40岁以上患者BPT的发生率和死亡率最高。不再使用博来霉素对获得完全缓解、PFS或OS无影响。
BPT导致HL治疗患者5年OS显著降低。年龄≥40岁似乎显著增加了风险。在未死于急性肺毒性的患者中,尽管不再使用博来霉素,但OS和PFS似乎相当。
