[Adjuvant chemotherapy for extranodal non-Hodgkin's lymphoma]

From 1976 to 1982, twenty-four cases with early stages (stage IE: 18, Stage IIE: 6) of extranodal non-Hodgkin's lymphomas were treated with combined modality of local treatment (radiation or operation) and an adjuvant chemotherapy consisting of vincristine, cyclophosphamide and prednisolone. Eighty-three percent of patients were diffuse histiocytic type. The most common sites of primary origin were in stomach; 13 patients and 7 patients in nasal or paranasal cavity. The disease-free survival rates at 5 years were 74% for stage IE and 80% for stage IIE, respectively. The result has suggested that adjuvant chemotherapy is a useful modality for extranodal non-Hodgkin's lymphoma.
