Twenty patients with advanced abdominal dissemination of ovarian carcinoma and 7 patients with intra-abdominal disseminated lymphoma were treated with moving strip therapy techniques, administering 3,000 r depth dose in 10 days time to each strip area. This dose is probably close to the maximum tolerated dose in the average case and unfortunately beyond that in some cases. This method is clinically more effective than, and the results, although poor enough, are more encouraging than those obtained when using large abdominal field techniques. The inherent dangers of this method are significant hematopoietic and acute gastrointestinal reactions.
