[Involved-node radiotherapy combined with deep-inspiration breath-hold technique in patients with Hodgkin lymphoma].

PURPOSE: To assess the clinical outcome of the involved-node radiotherapy (INRT) concept with the use of deep-inspiration breath-hold (DIBH) technique in patients with localized supra-diaphragmatic Hodgkin lymphoma.

PATIENTS AND

METHODS

All were patients with stage I-II Hodgkin lymphoma and they were treated with chemotherapy prior to irradiation. Radiation treatments were delivered using the involved-node radiotherapy concept according to the European Organization for Research and Treatment of Cancer Guidelines and a spirometer dedicated to DIBH radiotherapy was used for every patient.

RESULTS

Twenty-seven patients with Hodgkin lymphoma (26 patients with primary Hodgkin lymphoma, one with refractory disease), treated from November 2004 to October 2010, were retrospectively analysed. The median age was 27 years (range 16 to 54). Seventeen (63%) patients had stage I-IIA and 10 (37%) had stage I-IIB disease. All patients received two to six cycles of adriamycin, bleomycin, vinblastine and dacarbazine. The median radiation dose to patients was 30,6 Gy (range: 19,8-40). Protection of various organs at risk was satisfactory. Median follow-up, 3-year progression-free and 3-year overall survival were 38 months (range: 7-70), 96% (95%CI: 79-99%) and 95% (95%CI: 75-99%), respectively. Recurrence occurred in one patient (mediastinal in-field relapse). There was one grade 3 acute toxicity (transient pneumonitis).

CONCLUSIONS

Our results suggest that patients with localized Hodgkin lymphoma can be safely and efficiently treated using deep-inspiration breath technique and the involved-node radiotherapy concept. Longer follow-up is needed to assess late toxicity, especially for the heart and the coronary arteries.
