Idarubicin in combination with cytarabine and VP-16 in the treatment of post myelodysplastic syndrome acute myeloblastic leukemia (MDS-AML).

Fifteen patients with a primary myelodysplastic syndrome (MDS) transformed into acute myeloblastic leukemia (AML) were treated with an intensive chemotherapy regimen containing idarubicin. A complete response (CR) was obtained in 10 patients (66.6%). In five of them this was achieved after a single course of chemotherapy. The median time to achieve a CR was 32 days (range 16-42). A partial remission (PR) was obtained in 2 patients after two induction courses of chemotherapy. One patient died during the first induction course following acute respiratory distress syndrome (ARDS) complication, whereas the chemotherapy regimen failed in 2 patients. A short interval between MDS and transformation into AML was associated with a better chance of achieving a CR. Age, karyotype, type of MDS, peripheral blood or bone marrow findings appeared to have no influence on the response to treatment. The median event free survival for patients who achieved CR was 15 months and the median actuarial survival 18 months. These preliminary results need to be confirmed in a multicentre prospective study comparing idarubicin with other anthracyclines.

[Clinical course of refractory anemia. Study of a case series of 56 patients]. / Considerazioni sulla evoluzione clinica delle anemie refrattarie. Studio di una casistica di 56 pazienti.

We analysed the course and clinical features of a series of refractory anaemias (RA, RAEB, RAEBt). We could not find evidence to support the hypothesis that these three MDS classes are inevitably subsequent events of a single disease. Therefore aggressive treatment of RA, aimed at avoiding its evolution to RAEB or RAEBt, does not seem justified.

[Multiple myeloma. Role of prognostic factors and staging in a therapeutic program]. / Il mieloma multiplo. Ruolo dei fattori prognostici e della stadiazione in un programma terapeutico.

Patients affected with multiple myeloma constitute an heterogeneous population with very different clinical patterns, varying from asymptomatic to very compromised patients with severe and uncontrolled disease. Most common clinical and biological staging systems have been in use for many years. Recently new prognostic factors have been identified; among them, serum levels of beta-2 microglobulin, C-reactive protein and interleukin-6 employed with already known parameters have been useful in the new staging system, permitting a more focalized therapy. As today is not yet possible to define the best treatment schedule, as the most common treatments are incapable to eradicate myeloma neoplastic clone even in responsive patients. Nevertheless extensive use of biologic response modifiers in the last years, as alpha interferon, have added new powerful and hopeful therapeutic tools even if the results need to be confirmed in future trials. It is important to remind the primary role of bone marrow transplantation associated with high dose polychemotherapy even if just a minority of patients is eligible for this therapeutic chance.
