Complications of total abdominal and spleen irradiation in patients with lymphomas.

Fifty patients with non-Hodgkin's lymphoma were treated with total abdominal irradiation to a dose of 3000 rad by anterior and posterior fields treated the same day. Fourteen patients developed complications, four with intestinal obstruction due to stenosis and three with total or partial intestinal irradiation damage. These bowel complications were only seen in patients who had previously had a laparotomy. The ways of preventing these complications are discussed. We have studied renal function by means of clinical examination, biologic and radiologic investigations, and scanning in 75 patients who have received splenic irradiation to a dose of 4000 rad. With a mean follow-up time of 36 months, this study has shown that there was no significant change in blood pressure or in biochemical measurements. However, at the 17th month, nephrotomograms demonstrated cortical atrophy of the upper role of the kidney; at the 8th month, low uptake in the irradiated area was seen on 197Hg neohydrine scanning and a decrease in renal plasma flow in the left kidney during dynamic studies with Hippuran.
