[Malignant insuloma. Evaluation of the response to treatment with streptozotocin, using selective arteriography of the celiac axis].

A patients with metastatic insulin-producing islet-cell carcinoma has been treated with Streptozotocin intravenously and studied by selective celiac angiography during treatment. A 50% decrease of the tumor's size has been demonstrated by this technique after a total dose of 19 grams of the drug together with return to normal of the serum-insulin and blood-glucose values. The usefulness of angiography in evaluating the tumor response to Streptozotocin and in managing chemotherapy is discussed.
