Limited field radiotherapy for early stage, infra-diaphragmatic Hodgkin's lymphoma.
OBJECTIVE
To analyse the treatment outcome for patients with stage I and II infra-diaphragmatic Hodgkin's lymphoma.


METHODS
A retrospective review of case notes for 33 consecutive patients treated between 1988 and 2000. Twenty-five out of 33 patients received radiotherapy alone, three out of 33 patients received minimal initial chemotherapy (MIT) (4 weeks VAPEC B) and five patients received six cycles of ChlVPP EVA hybrid chemotherapy before radiotherapy. Radiotherapy was given as a limited field in 32 out of 33 patients.


RESULTS
Twenty-seven out of 33 patients were men (82%), and the median age was 47 years. Fifteen of the 33 patients were stage IA, 15 were IIA, 1 was IB and 2 were IIB. The median follow-up was 71 months. Histological subtype was lymphocyte predominant (15/33), nodular sclerosis (11/33), mixed cellularity (4/33), lymphocyte-rich classical (1/33) and unclassifiable (2/33). The 5-year overall survival was 89% and 5-year relapse-free survival was 85%. The median time to relapse was 37 months (range 7-65 months). One out of five relapses was within the previous radiotherapy field. All five relapses had received radiotherapy alone and four were salvaged with chemotherapy. There have been four second malignancies and one patient transformed to high-grade non-Hodgkin's lymphoma. No patient has died of Hodgkin's lymphoma.


CONCLUSIONS
In our cohort of patients with infra-diaphragmatic stage I and II Hodgkin's lymphoma treated with limited-field radiotherapy, no patients died from uncontrolled disease. The use of MIT may reduce the risk of relapse and obviate the need for conventional salvage chemotherapy. Late relapses may occur, and second malignancies are a cause for concern underlining the need for long-term follow-up.
