Colonic ischemia (CI) is a rare complication of high-dose interleukin-2 (IL-2) immunotherapy. This complication occurred in three of 141 patients (2.1%) with metastatic cancer treated with high-dose IL-2 therapy; CI only developed in patients receiving interferon-alpha (IFN) with IL-2 (three of 21, 14%) compared with none of 120 in those patients receiving IL-2 alone (P equals 0.0009). Severe diarrhea (greater than or equal to 7 bowel movements/day) also was significantly more common in patients receiving IFN with IL-2 (six of 21, 29%) than in those receiving IL-2 alone (three of 120, 2.5%, P equals 0.001) and preceded the clinical diagnosis of CI in all three patients. Three of nine patients with severe diarrhea had CI. Hematochezia occurred in four patients, all of whom received IFN with IL-2; three had CI, and the other patient had nonspecific colitis. Differences in vasopressor use did not explain the increased risk of CI in patients receiving IFN; those receiving IFN with IL-2 required phenylephrine less often than patients receiving IL-2 alone (P equals 0.01). The administration of lymphokine-activated killer (LAK) cells had no significant effect on the incidence of CI, severe diarrhea, peritonitis, or vasopressor use; two of three patients with CI, however, had their ischemic episode within 24 hours after the last of three LAK cell infusions. In conclusion, CI is an unusual complication of high-dose IL-2 and IFN immunotherapy. In patients receiving such combination therapy, severe diarrhea is a risk factor for the subsequent occurrence of CI.

From 1987 to 1995, 22 children with refractory solid tumors entered a phase II study of high-dose thiotepa (HDT) (900 mg/m2) followed by stem cell transplantation (SCT) in the Pediatrics Department of the Institut Gustave Roussy. Tumor types were rhabdomyosarcoma (eight), osteosarcoma (seven), neuroblastoma (three), Ewing's sarcoma (three) and Burkitt's lymphoma (one). Before HDT, all had been extensively treated with conventional chemotherapy, surgical resection of the primary tumor (13/22) and of metastases (6/22), and radiotherapy of the primary tumor in three patients. All had measurable disease, at the site of the primary tumor (3 patients), of the metastases (9 patients) or both (10 patients). Toxicity from the HDT was severe but acceptable. No toxicity-related death occurred. The median duration of neutropenia and thrombocytopenia was 18 days (5-37) and 30 days (7-377), respectively. Septicemia was documented in four patients. Severe diarrhea was observed in seven patients. Mild hepatic toxicity occurred 18 times. No CR and 11/22 PR were documented: osteosarcoma 4/7, rhabdomyosarcoma 4/8, Ewing's sarcoma 2/3; 1/1 Burkitt's lymphoma progressed. We conclude that at a dose of 900 mg/m2 followed by SCT support in these heavily pretreated children, the main toxicity induced by thiotepa was digestive. The response rate observed, especially in sarcoma, is particularly encouraging. Thiotepa should be further evaluated in HDC regimens either in combination with other alkylating agents or in rapidly cycled courses of HDC with SCT.
