PURPOSE: Asbestos exposure is the major known risk factor for mesothelioma,
but several case reports have suggested a link between radiation therapy
and subsequent development of malignant mesothelioma. This report explores
a possible association between radiation therapy for Hodgkin's disease and
mesothelioma. PATIENTS AND METHODS: Four cases of malignant mesothelioma
were observed following Hodgkin's disease at the Mesothelioma Clinic of the
Dana-Farber Cancer Institute. A fifth such patient was found after a review
of the literature. RESULTS: In all five cases, the mesothelioma arose in
the field of prior radiotherapy. No history of asbestos exposure was
elicited by careful questioning or by review of chest radiographs.
Examination of lung tissue in one patient showed 250 ferruginous bodies per
gram of lung tissue, consistent with no significant prior exposure. The
mean interval between radiation treatment for Hodgkin's disease and
development of mesothelioma was 15 years, which emphasizes the need for
continued follow-up and evaluation of these patients and supports a causal
relationship. CONCLUSION: Mesothelioma may need to be added to the list of
second malignancies that arise following radiation therapy for Hodgkin's
disease. Further support is given to a causal link between radiation
exposure and mesothelioma.
