[Injections of mitoxantrone, VUFB Praha, in the treatment of acute myeloid leukemia and non-Hodgkin's lymphoma]. / Mitoxantron injekce VUFB Praha v lécbe akutních myeloidních leukémií a nehodgkinovských lymfomu.

Mitoxantrone injections (Mx), VUFB Prague, were administered to 24 patients with acute myeloid leukaemia (AML) and non-Hodgkin lymphoma (NHL). Patients with NHL were treated by monotherapy with Mx or by polychemotherapy in combination with CMOP (cyclophosphamide, mitoxantrone, vincristine, prednisone). To patients with AML Mx was administered 1x during induction treatment as monotherapy, in the remaining nine patients as post-remission treatment or re-induction treatment in combination with medium doses of cytosine arabinoside (IDAC + Mx). A positive therapeutic effect was observed in NHL with a high or medium degree of malignity during primary as well as during secondary treatment. Very good therapeutic results with Mx were achieved in AML in induction, post-remission and even re-induction treatment with a minimal haematological and non-haematological toxicity.

[Treatment of medium and highly malignant non-Hodgkin's lymphoma with combined chemotherapy using methotrexate, adriamycin, cyclophosphamide, vincristine, prednisone and bleomycin (protocol MACOP-B)]. / Lécba stredne a vysoce maligních nehodgkinských lymfómu kombinovanou chemoterapií metotrexátem, adriamycinem, cyklofosfamidem, vinkristinem, prednisonem a bleomycinem (protokol MACOP-B).

Combined chemotherapy, protocol MACOP-B, was administered to 21 patients with non-Hodgkin lymphoma (NHL) with a medium or high grade of malignity, clinical stage II-IV. Complete remission was achieved in 17 patients (81%), in one instance partial remission was induced. One patient died from a cardiovascular and one from a thromboembolic complication during treatment. In one patient the results were not evaluated. Three patients developed severe granulocytopenia which called for reduction or delay of treatment and a septic condition developed. In addition to myelosuppression the main complications were stomatitis and mycosis. No death caused by infectious or haemorrhagic complications was recorded. The described chemotherapy is recommended in particular in immunoblastic lymphomas, diffuse lymphomas from cleaved and non-cleaved cells and diffuse lymphomas with mixed cellularity.
