Bolus chemotherapy with vincristine, actinomycin D, and cyclophosphamide was administered to 31 patients with solid tumors. Among 12 patients with measurable disease who had not received prior treatment, a complete response was achieved in one with Ewing's sarcoma and a partial response was achieved in another with rhabdomyosarcoma. The dose-limiting toxicity was granulocytopenia.

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.

Purpose. This study investigates the efficacy and toxicity of daily oral etoposide in chemotherapy for non-heavily pretreated advanced and metastatic soft tissue sarcoma (STS).Subjects. Twenty-seven patients with progressive and measurable disease were treated. Median age was 53 years (range 20-71 years) and performance status WHO 0 or 1. Histologies included mainly leiomyosarcoma (8), malignant fibrous histiocytoma (4), rhabdomyosarcoma (4), liposarcoma (2) and synovial sarcoma (2). Fifteen patients had received prior radiotherapy, of whom three included sites with haematopoiesis. All patients had received prior chemotherapy, including adjuvant therapy (7) and mostly consisted of one two-drug schedule (ifosfamide and doxorubicin) or two single-drug regimens.Methods. Chemotherapy consisted of etoposide (VP16-213), 50 mg m(-2) day(-1) x 21 q 4 weeks. Blood cell counts were done weekly. Dose reductions and a maximum delay of 2 weeks was allowed depending on cell counts during treatment and at the start of a new 4-week treatment cycle.Results. No objective response was observed. Progressive disease was observed after two treatment cycles in 17/27 patients (68%) and after three cycles in 22/27 patients (81%). The other patients received three to five cycles. Twenty-four patients went off study due to progressive disease. Grade 3 and 4 neutropenia was observed in eight and one patients, respectively. Thrombocytopenia grade 3 was seen in two patients. Non-haematological toxicity grade 3 (nausea, diarrhoea or alopecia) was observed in three patients, and grade 4 (dyspnea, hypotension or haemorrhage) in three patients.Discussion. No objective response was obtained. Oral etoposide at a dose of 50 mg m(-2) day(-1) x 21 q 4 weeks is inactive in chemotherapy of pretreated STS. Disease progression occurred within three cycles in the majority (81%) of patients. Toxicity of this regimen in non-heavily pretreated patients is low.
