Two patients with solid tumors were treated with 21-day continuous infusion topotecan as palliation therapy. Case 1: A 10-year-old girl was diagnosed with progressive, metastatic hepatocellular carcinoma. Twenty-one–day continuous infusion topotecan was started and she has had a partial response. Case 2: A 17-year-old girl developed a malignant fibrous histiocytoma as a second malignant neoplasm. After partial resection and failure of multiagent chemotherapy, she started continuous infusion topotecan and was disease-free for 58 months when she died of pneumonia. These cases suggest that topotecan given as 21-day continuous infusion is efficacious for palliation care.
