Dose-intensified treatment strategies for Hodgkin lymphoma (HL) have demonstrated improvements in cure but may increase risk for acute and long-term toxicities, particularly in children. The Children's Oncology Group assessed the feasibility of a dose-intensive regimen, BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone) in children with high-risk HL (stage IIB or IIIB with bulk disease, stage IV). Rapidity of response was assessed after 4 cycles of BEACOPP. Rapid responders received consolidation therapy with guidelines to reduce the risk of sex-specific long-term toxicities of therapy. Females received 4 cycles of COPP/ABV (cyclophosphamide, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, vinblastine) without involved field radiation therapy (IFRT). Males received 2 cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) with IFRT. Slow responders received 4 cycles of BEACOPP and IFRT. Ninety-nine patients were enrolled. Myelosuppression was frequent. Rapid response was achieved by 74% of patients. Five-year event-free-survival is 94%, IFRT with median follow-up of 6.3 years. There were no disease progressions on study therapy. Secondary leukemias occurred in 2 patients. Overall survival is 97%. Early intensification followed by less intense response-based therapy for rapidly responding patients is an effective strategy for achieving high event-free survival in children with high-risk HL.

剂量强化治疗策略在霍奇金淋巴瘤(HL)中已经证明可以提高治愈率,但可能会增加急性和长期毒性的风险,尤其是在儿童中。儿童肿瘤学组评估了剂量强化方案 BEACOPP(博来霉素、依托泊苷、多柔比星、环磷酰胺、长春新碱、丙卡巴肼、泼尼松)在高危 HL(IIB 期或 IIIB 期有肿块疾病、IV 期)患儿中的可行性。在接受 4 个周期的 BEACOPP 治疗后评估了快速反应。快速反应者接受巩固治疗,指南旨在降低治疗的性别特异性长期毒性风险。女性接受 4 个周期的 COPP/ABV(环磷酰胺、长春新碱、丙卡巴肼、泼尼松、多柔比星、博来霉素、长春碱),无需接受受累野放射治疗(IFRT)。男性接受 2 个周期的 ABVD(多柔比星、博来霉素、长春碱、达卡巴嗪)加 IFRT。缓慢反应者接受 4 个周期的 BEACOPP 和 IFRT。共有 99 名患者入组。骨髓抑制很常见。74%的患者达到快速反应。中位随访 6.3 年后,5 年无事件生存率为 94%,IFRT。研究治疗期间无疾病进展。2 例发生继发性白血病。总生存率为 97%。快速反应患者早期强化治疗,然后进行基于反应强度较低的治疗,是一种在高危 HL 患儿中实现高无事件生存率的有效策略。该试验在 http://www.clinicaltrials.gov 注册,编号为 #NCT00004010。
