title: Treatment of acute non lymphoid leukemia (ANLL) in elderly patients. The GIMEMA experience.
abstract: The results of four consecutive trials designed by the GIMEMA group for the treatment of ANLL in elderly patients are reviewed. Complete remission (CR) has been achieved in 20.8% of patients older than 60 years treated with 5-day courses of ARA-C plus thioguanine, in 22.7% of patients treated with high dose ARA-C (HDARAC) plus Asparaginase, in 39.5% of patients aged 55 to 80 receiving either Idarubicin or Daunorubicin in combination with Cytarabine in a standard 3+7 protocol and in 51% of patients older than 60 years treated with intermediate dose ARA-A (IDARAC) plus Mitoxantrone. From 1988, patients ineligible for aggressive chemotherapy entered a study of palliative treatment with Thioguanine and ARA-C. This 18 year GIMEMA experience showed that: CR can be obtained only with regimens producing marrow aplasia, the inclusion of anthracyclines or Mitoxantrone improves the CR rate, without prohibitive toxicity, haematological toxicity is very high in elderly patients and account for the most frequent cause of treatment failure namely death in aplasia, palliative treatment does not improve the quality of life and prolongs median survival only slightly. When comparing the results of these trials, it appears that in the GIMEMA group the capability of offering effective treatment to elderly patients with ANLL has continuously improved and that IDARAC plus Mitoxantrone is so far the most active and best tolerated regimen. Death in aplasia remains a major problem and future trials will be aimed at exploiting the possibility of reducing the haematological toxicity by using recombinant colony stimulating factors.
