    Notes: Abstract A frequent change of drug combinations may circumvent drug resistance in the treatment of patients with acute lymphoblastic leukaemia (ALL). In study COALL 85/89 201 children with high-risk ALL were randomized to receive over a period of 8 months rotational chemotherapy with six drug combinations given either in slow rotation (SR) (each combination given twice in succession) or in rapid rotation (RR) (cach combination given once with a repetition of the drug combinations). Treatment of central nervous system leukaemia consisted of cranial irradiation and intrathecal methotrexate. Both SR and RR treatment groups were then given continuation chemotherapy of oral 6-mercaptopurine and methotrexate until 2 years after the date of diagnosis. The 9-year eventfree survival (EFS) rate for the whole group is 69%±3%, and the survival rate 75%±3% at a median follow up of 5.8 years. Failure to achieve remission at day 28 was the most important prognostic factor (EFS 12%±7% vs. 75%±3% in the remission group). In the RR group, 11/100 patients were not in remission at day 28 opposed to 7/101 patients in the SR group. Children aged 〈1 year (6/6 relapses) or aged 〉=10 years had a worse prognosis (EFS 64%±5% vs. 77%±4% in patients 1–10 years old). After 5 years EFS was inferior in the RR group attributable to a significantly higher relapse rate in children with a WBC〉=100/nl. The EFS at 9 years for all patients, however, is similar in both groups (SR 72%±5% vs. RR 67±5%).

In the RR group, 11/100 patients were not in remission at day 28 opposed to 7/101 patients in the SR group. Children aged 〈 1 year (6/6 relapses) or aged ^ 10 years had a worse prognosis (EFS 64% ± 5% vs. 77% ± 4% in patients 1–10 years old). After 5 years EFS was inferior in the RR group attributable to a significantly higher relapse rate in children with a WBC ^ 100/nl. The EFS at 9 years for all patients, however, is similar in both groups (SR 72% ± 5% vs. RR 67 ± 5%). Conclusion The COALL 85/89 treatment protocol with early intensive therapy and rotation of different drug combinations offers long-term disease-free survival for children with high-risk ALL. A continuous 4-week exposure to one drug combination may be necessary to achieve optimal results, especially in children with a high leukaemic cell burden.

    Notes: Abstract We report a case of congenital Langerhans cell histiocytosis (LCH), presenting with a generalized varicelliform rash in an otherwise well newborn. No signs of organ involvement were found on repeated skeletal radiography, abdominal ultrasonography and laboratory studies. A diagnosis of “pure cutaneous” LCH was established. Skin manifestation was unusually severe and recurred during the first 20 months of life, but responded well to combination chemotherapy (methylprednisone, vinblastine) while the child continued to thrive. At the age of 2 years the patient presented with acute onset diabetes insipidus due to infiltration of the hypothalomo-pituitary stalk region. He died for reasons unknown at the age of 28 months. Conclusion“Pure cutaneous” LCH, frequently also referred to as congenital self-healing LCH, is a variable disorder which may be complicated by late organ involvement. Close follow up and thorough diagnostic evaluation is therefore mandatory.

    Intermediate-dose methotrexate in the treatment of childhood acute lymphocytic leukaemia: lack of benefit during maintenance therapy following intensive induction therapy (1986)

    Notes: Abstract One hundred and fifty-one children with acute lymphocytic leukaemia (ALL) received multiple agent induction chemotherapy followed by intensive phase treatment. One hundred and thirty-seven patients were randomised for the first year of maintenance treatment to receive reinforcement therapy (pulses) with either intermediate-dose methotrexate (ID-MTX) and prednisone (PRED) or vincristine (VCR) and PRED. The probablity of continuous complete remission (CCR) at 5.5 years is 0.80 for the ID-MTX group and 0.84 for the VCR group. Extramedullary relapses were not prevented either in the ID-MTX group nor in the VCR group. Since in previous studies VCR/PRED pulses did not increase CCR rates when given after intensive combination chemotherapy, it can be concluded from this study that neither did ID-MTX reinforcement therapy further improve treatment results in our patients with ALL when given after aggressive chemotherapy.

    Description / Table of Contents: Summary Two children developed multiple melanocytic naevi after polychemotherapy administered for acute lymphoblastic leukaemia in one and for non-Hodgkin lymphoma in the other. Induction of naevi does not seem to be related to specific agents used in chemotherapy, but rather to the immunosuppression resulting from multiple-agent chemotherapy. There are reports in the literature of both intrinsically and iatrogenically immunosuppressed patients who have developed multiple melanocytic naevi.
    Notes: Zusammenfassung Es wird über 2 Kinder berichtet, bei denen es nach Einsatz unterschiedlicher Polychemotherapieschemata aufgrund onkologischer Erkrankungen (akute lymphoblastische Leukämie bzw. Non-Hodgkin-Lymphom) zum Auftreten zahlreicher NZN kam. Ursächlich für die Induktion der Naevuszellnaevi scheint kein substanzspezifischer Mechanismus zu sein, sondern die durch die Chemotherapie bedingte Immunsuppression. In der Literatur finden sich Mitteilungen über ein vermehrtes Auftreten melanozytärer Neubildungen im Zusammenhang mit Therapie -oder Erkrankungs-bedingten Zuständen von Immunsuppression.

    T-cell acute childhood lymphoblastic leukemia with chromosome 14q11 anomaly: a morphologic, immunologic, and cytogenetic analysis of 10 patients (1988)

    Notes: Summary Ten patients with T-cell acute lymphoblastic leukemia (ALL) and a chromosome anomaly involving band 14q11 are described. Mitotic index of bone marrow blasts was high in all patients (average 3.0%). Lymphoid morphology of the leukemic blasts, however, varied somewhat among the patients. The leukemic cells of 5 patients showed an immunophenotypic profile corresponding to early or common thymic differentiation stages whereas 5 children showed strong expression of CD3 suggesting a more mature thymic phenotype. Leukemic karyotypes revealed a modal chromosome number of 46 in 9 cases, 92 in one case. A chromosome translocation t(11; 14) (p13; q11) was found in 5 cases, a t(1; 14) (p32; q11) in 2 cases, a t(10; 14) (q24; q11) in one case, a (hitherto undescribed) t(12; 14) (q22; q11) in one case, and an inv(14) (q11 q32) in one patient. Additional abnormalities were t(3; 10), t(7; 9), dup (7q), del (6q), del (10q), and del (1 q). Of 32 cases with T-cell ALL successfully karyotyped in our laboratory 15 (=47%) had structural aberrations involving chromosomes 1, 3, 6, 7, 9, 10, 12, 14. Ten of these 15 patients (=67%) had a chromosome 14q11 anomaly. It is concluded that chromosome band 14q11, the gene locus of the T-cell receptor α-chain, is the most common site for structural chromosome aberrations in T-cell ALL.
