Between 1990 and 1996, we conducted a randomized trial in adults with newly diagnosed acute myeloid leukemia (AML) in order to compare relapse-free interval (RFI) after double induction (arm B), timedsequential induction (arm C), or control "3 ؉ 7" induction (arm A). Patients achieving complete remission (CR) after induction ؎ salvage received the same consolidation chemotherapy, which included a dosage stratification according to patient's age (younger or older than 50 years). This long-term analysis was performed in 592 patients (arm A/B/C, 197/ 198/197 patients). Overall CR rate was 76% without differences between the 3 arms, even if a salvage course was less frequently needed in arm B. Treatmentrelated mortality, either during the induction or the postremission phase, was not significantly higher in arms B and C than in arm A. Among the 449 CR patients, 250 relapsed (arm A/B/C, 90/87/73 patients) without significant differences in RFI in arms B and C versus arm A (P ‫؍‬ .39 and .15, by the Gray test). However, when analyzing the 345 patients younger than 50, RFI was significantly improved in younger patients receiving timed-sequential induction (P ‫؍‬ .038 by the Gray test), while not in those receiving double induction. Event-free survival and overall survival were similar in the 3 randomization arms.

From 1968 to 1993, 179 newly diagnosed patients with polycythemia vera (PV) were enrolled in a prospective study using pipobroman as first chemotherapy. Among them, 140 fulfilled the Polycythemia Vera Study Group criteria for PV, and 39 patients (22%) can be considered as idiopathic erythrocytosis (IE). Vascular events occurred in 10% of IE and 20% of PV patients and solid tumors in 7.7% of IE and 12.8% of PV patients. There were no differences between PV and IE patients with regard to progression to myelofibrosis (MF), leukemic events and overall survival. Overall, 98.3% of patients initially responded to pipobroman, with very mild toxicity. A total of 164 PV patients who received more than 1 year of pipobroman were analyzed for long-term evolution. The actuarial risk of thrombosis was 15.6 and 23.8% at 10 and 18 years, respectively. In all, 21 patients developed a solid tumor during follow-up, added and/or switched drugs being a risk factor. Actuarial risk of MF was as low as 4.9 and 9.4% at 10 and 15 years, respectively. Actuarial risk of leukemia was 14.4 and 18.7% at 10 and 15 years, respectively. Hyperleukocytosis at diagnosis was the only variable significantly associated with higher risk of leukemia. The median survival was 15.5 years, with two initial adverse prognostic factors: age above 60 years and hyperleukocytosis. Despite an increasing risk of leukemia with time, survival was not lower when compared to the French matched population. Only age and hyperleukocytosis at diagnosis were found to have a prognostic value in PV.

We aimed to perform a prospective analysis of the main characteristics of deaths occurring in the oncohaematology department of a general hospital. From November 1995 to February 1997, a total of 81 patients died in our unit, 50 of whom (61.7%) were male. Their mean age was 67.8 (range 19-96) years. Underlying diseases were: multiple myeloma (9 cases), acute myeloid leukaemia (22), lymphoma (14), chronic lymphocytic leukaemia (6), acute lymphoblastic leukaemia (4), myelodysplastic syndromes (3), solid tumours (11), and other (12). The previous disease duration ranged from 5 days to 276 months (mean 31.9 months). The duration of the last hospital stay varied between 0 (death on arrival or on way to hospital) and 40 days (mean 9.3 days). Two patients died in the emergency unit just before entering our department (1 suicide). Only 15 patients had been admitted for the first time. In 70% of these cases death appeared predictable, as the consequence of refractory or end-stage disease. In these cases, all the "do not resuscitate" orders were in place at least 48 h before death. About half the patients died without any relative present. The frequencies of the clinical complaints evaluated were the following: pain necessitating opiates 27%; infection- or disease-related fever 40%; dyspnoea 44%; haemorrhage 20%; CNS disturbances 25%. The percentages of use of therapy tools chosen as indicators were: benzodiazepines 80%; chemotherapy 46%; anti-infectious agents 47%; transfusions 42%; major analgesics 27%; and steroids 40%. The circumstances and quality of patient deaths must be regularly evaluated so that palliative care in the final stages of life can be improved.

A Ph-positive CML patient who had received a peripheral blood stem cell autograft in chronic phase demonstrated a transient regression of the Ph-positive clone with the concurrent appearance of another clone with trisomy 8. This latter clone disappeared when the patient received alpha-interferon.
