    Notes: Summary Twenty-nine children with tumours that had failed to respond to conventional therapy have been treated with AMSA. There were 16 patients with haematological malignancies in whom treatment was initiated at 25 mg/m2 for 3 days, increasing to 150 mg/m2 for 5 days. There were one complete and four partial remissions in these patients, all of whom had received at least 500 mg AMSA/m2. Thirteen children with solid tumours were treated. They received single doses of 120 mg/m2 initially, increasing to 100 mg/m2 for 5 days. No complete or partial responses occurred, but some antitumour activity was noted in neuroblastoma and retinoblastoma. Dose-related severe bone marrow toxicity occurred, but gastrointestinal and other toxicity was mild. An additional patient with T cell lymphoma, who received AMSA prior to a successful autologous bone marrow transplant, is described. AMSA is an active drug in childhood leukaemia. Further studies at the maximum tolerated dose are needed to assess enough patients with any single solid tumour type. In particular, the response of neuroblastoma warrants further study. Investigation of the use of AMSA either prior to bone marrow transplantation in leukaemia or in association with autologous marrow transplant in neuroblastoma and other solid tumours may be of value.

    Notes: Summary A study was begun in 1971 at St. Bartholomew's Hospital with a combination of 4 drugs, dactinomycin (actinomycin D), adriamycin, vincristine and Endoxan (cyclophosphamide) (D.A.V.E.), together with surgery and radiation, in the treatment of stage III and stage IV Wilms' tumour. Seventy-one percent of the children treated achieved complete response. The median survival from diagnosis was 19 months, and in those children achieving complete response the median disease-free survival has not yet been reached. Toxicity was not a serious problem. The study group is compared with a group of children treated at this hospital before 1971. There is an improved survival in the children treated with D.A.V.E. Children who have relapsed with stage I or stage II disease may also respond. This four-drug combination was well tolerated and effective, and confirms recent experience suggesting that intensive multiple-drug regimens may be curative even in advanced disease.

    Notes: Summary A phase I study of human lymphoblastoid interferon (IFN-α) was undertaken in patients with acute leukaemia and other malignancies. The pharmacokinetics of intravenous IFN-α were also investigated. IFN-α was administered to two patients by intravenous (IV) bolus injection at a dose of 5×106 U/m2; and to a further 37 patients (40 cycles) by continuous intravenous infusion (IVI) for 5, 7, or 10 days at doses ranging from 5 to 200×106 U/m2/day. Pyrexia, general malaise, anorexia, and rigors were observed at all dose levels; three patients became hypotensive. Myelosuppression occurred in all patients, including seven without bone marrow infiltration. Transient rises in alkaline phosphatase and transaminases (SGOT) were observed in patients receiving daily doses greater than 30×106 U/m2. Dose-limiting central nervous system toxicity, hyperkalaemia, and hypocalcaemia were encountered at 200×106 U/m2. In six patients with acute leukaemia there was a fall in the number of circulating leukaemic blasts and in one patient with acute myelogenous leukaemia (AML) the degree of bone marrow infiltration decreased from 99% to less than 5% with cellularity returning to normal. Serum levels of IFN above 1,000 U/ml were achieved with daily doses above 30×106 U/m2 given by IVI. The maximum safely tolerated daily dose, 100×106 U/m2 administered for 7 days, is appreciably higher than that used in most previous studies, although even at this level consideralbe toxicity may be encountered.

    Notes: Summary Eight of 36 children receiving maintenance chemotherapy for acute lymphoblastic leukaemia or non-Hodgkin's lymphoma had liver biopsies on the basis of clinical abnormalities and/or elevated serum enzyme levels. Six biopsies were abnormal, including one in a boy with spider naevi who showed micronodular cirrhosis; he appeared to retain methotrexate in the blood for a prolonged period and his SGOT level did not return to normal for 19 months after maintenance chemotherapy was discontinued. The five other abnormal biopsies showed minor changes in the portal tracts. The six children with abnormal liver histology showed a wide variation in their early handling of an oral methotrexate dose. There was a statistically significant rise in mean SGOT and alkaline phosphatase during treatment, but the wide scatter in values precluded their use as accurate indicators of liver damage in these children.

    Notes: Summary Twenty-six patients with acute leukaemia and 14 with high-grade lymphoma received cytosine arabinoside (ara-C) at a twice daily dose of 2 g/m2 administered as a 3-h infusion. Thirty-four patients received 12 doses and six electively received four doses only. Complete remission was achieved in six of seven patients with acute myelogenous leukaemia (AML), one of two evaluable patients with blast crisis of chronic myeloid leukaemia and three of eight patients with acute lymphoblastic leukaemia (ALL). Three further patients with ALL had only minimal bone marrow infiltration after one cycle, toxicity precluding administration of a second. Three patients with AML who received four doses only showed no evidence of response. Four of 14 patients with lymphoma who received 12 doses, entered complete remission. Five additional patients died with minimal residual disease whilst severely neutropenic. A complete and a partial response were seen in two patients with immunoblastic and centrocytic lymphoma respectively who received four doses. These results confirm the activity of high-dose ara-C in patients with AML and suggest that it may also be a potentially useful agent in ALL and high-grade lymphoma, especially as the incidence of CNS toxicity is lower than that reported at higher doses.
