早期霍奇金病综合治疗中受累野照射的临床疗效

目的 评价Ⅰ、Ⅱ期霍奇金病（HD）患者综合治疗时受累野照射的疗效和毒副作用,并与扩大野照射进行比较。方法 早期HD 88例,根据Ann Arbor分期,ⅠA期12例（13．7％）,ⅡA期56例（63．6％）,ⅡB期20例（22．7％）。全部患者接受化疗和放疗综合治疗,先化疗后放疗患者83例,先放疗后化疗患者5例。化疗多采用ABVD或ABVD／MOPP方案;受累野照射42例,扩大野照射46例。结果 全组有6例膈上原发HD治疗后复发,受累野组和扩大野组各3例。扩大野组有1例照射野内复发,受累野组有1例在邻近照射部位的腋窝复发,其余4例患者均表现为结外器官或膈下淋巴结受侵。全组患者1、2、3年总生存率分别为100．0％、98．6％和96．3％,受累野组患者分别为100．0％、97．1％和97．1％,扩大野组患者分别为100．0％、100．0％和95．8％,两组生存率差异无统计学意义（P=0．86）。受累野组1、2、3年无进展生存率分别为97．6％、94．8％和91．7％,扩大野组分别为97．8％、93．2％和93．2％,两组无进展生存率差异无统计学意义（P=0．65）。发生Ⅰ度和Ⅱ度白细胞减少症者,受累野组3例（7．2％）,扩大野组9例（19．5％,P=0．089）。结论 Ⅰ、Ⅱ期HD患者进行综合治疗时,采用受累野照射可获得与扩大野照射相同的疗效,且能减少并发症的发生。

Comparison of preliminary results of involved-field with extended field radiotherapy combined with chemotherapy for early stage Hodgkin's disease

OBJECTIVE: To evaluate whether involved-field (IF) radiotherapy is equally effective and less toxic in comparison with extended-field (EF) radiotherapy for patients with early-stage Hodgkin's disease (HD) who received combined modality therapy. METHODS: The data of 88 early-stage HD patients treated with combined modality therapy were retrospectively reviewed. According to Ann Arbor classification, 12 patients (13.7%) had stage IA disease, 56 stage IIA (63.6%), and 20 IIB (22.7%). Forty-two (47.7%) patients underwent involved field radiotherapy (IF group), whereas the other 46 (52.3%) received extended field radiotherapy (EF group). RESULTS: Of 6 patients who developed recurrence, 3 (7.1%) were in IF group and the other 3 (6.5%) in EF group. Only one patient's recurrence developed inside the radiation field in EF group. Three patients (7.2%) in IF group and 9 (19.5%) in EF group had WHO grade 1 and 2 leukopenia (P = 0.089). Overall survival rate at 1-, 2- and 3-year was 100.0%, 97.1%, and 97.1% in IF group versus 100.0%, 100%, and 95.8% in EF group (P = 0.86), respectively. Freedom from progression survival rate at 1-, 2- and 3-year was 97.6%, 94.8%, and 91.7% in IF group versus 97.8%, 93.2%, and 93.2% in EF group (P = 0.65), respectively. CONCLUSION: Compared with extended-field radiotherapy, involved-field radiotherapy is equally effective and less toxic for patient with early-stage Hodgkin's disease treated with combined modality therapy.
