[Half-body irradiation and XXXX . Apropos of 9 cases].

@entity1 @entity1893 @entity3894
Nine @entity1 , aged 19 to 57 years (mean: 37 years) with @entity1893 ( @entity1893 ) secondarily resistant to chemotherapy (8 stages CS IV involving the bone marrow and 1 stage III) were studied. Histologic forms according to the Lennert classification were as follow: 1 nodular centrocytic which developed into a diffuse centroblastic, 3 diffuse immunoblastic, 4 diffuse centrocytic-centroblastic, and 1 T cell lymphoblastic. The nine @entity1 were managed by external irradiation of the lower half of the body (LHBI), followed six weeks later by irradiation of the upper half of the body (UHBI). A single dose of 8.00 Gy in 7 cases and 6.00 Gy in 2 cases was delivered. Three @entity1 developed severe medullary @entity3894 . Each of these @entity1 had received 8.00 Gy and been given a course of chemotherapy between the two radiation sessions. The @entity3894 was fatal in two @entity1 . Overall apparent clinical remission rate was 5/9, with one iatrogenic death at 3.5 months; one lost to follow-up after 8 months; for three other cases, the duration of apparent complete remission was 15, 22 and 36 months. One @entity1 was alive in partial remission 30 months after irradiation. Three @entity1 who failed to respond to treatment, were died between 4 and 11 months.
