Résumé : One hundred and sixty-two patients with advanced solid tumors were treated with oral dianhydrogalactitol 30 mg/m2 daily for 10 days every 4-6 weeks. Dose limiting toxicity was hematopoietic. Eight objective responses were seen in 136 evaluable cases. Patients with gastro-intestinal cancer ( 2 13 gastric, 1 3 pancreatic, 2 23 colorectal) showed objective regressions lasting 1-12 + months. Short lasting partial remissions occurred in 2 20 lung epidermoid and 1 18 breast carcinomas. Dianhydrogalactitol has limited chemotherapeutic activity against adult solid tumors but deserves further trial in gastro-intestinal malignancies. © 1979.
