Non Hodgkin's lymphomas following chemoradiotherapy for Hodgkin's disease. Two new cases and a review of the literature.

ABSTRACT

Two patients developed non-Hodgkin's lymphoma (NHL) six and ten years after radiotherapy and chemotherapy for Hodgkin's disease nodular sclerosis type. The histological classification of the developing NHL for the two patients was IgG (K) secreting lymphoplasmacytoid lymphoma of the stomach, and immunoblastic lymphoma of the cervical lymph nodes. Both patients responded well to conventional chemotherapy for NHL and are alive 22 and 5 months after the diagnosis of the secondary tumor. Forty eight cases of NHL after treatment for HD have been previously reported. We present a review of the literature of these cases, adding to this literature the first reported case of gastric lymphoplasmacytoid lymphoma under such circumstances.
