Thirty-one elderly patients with measurable advanced breast cancer entered this phase II study. A dose of 15 mg/m2/day of Idarubicin (IDA) for 3 consecutive days every 3 weeks was given orally. Mean total cumulative dose of IDA received was 175 mg/m2 (range: 45-475 mg/m2). Mean number of cycles given was four (range: 1-15). Out of 27 evaluable patients, three achieved a complete response (CR), four had a partial response (PR) (CR + PR = 26 +/- 17%), nine showed no change, and 11 had a progressive disease. Median time to progression was 83 days (range: 19-728 days). Out of 26 patients evaluable for toxicity, hematologic toxicity at day 21 was moderate: neutropenia grades 3 and 4 = 16% of cycles: two patients had grade 1 thrombopenia; and three patients, grade 3. No cumulative hematologic toxicity was detected. Nonhematologic toxicities consisted of nausea and vomiting in 72% of patients [World Health Organization (WHO) grades 3 and 4 = 8%)] and alopecia in 76% (WHO grades 2-3 = 38%). Grade 1 stomatitis occurred in 4% of cycles. Chemotherapy was discontinued in one patient because of drop of left ventricular ejection fraction (LVEF) from 0.62 to 0.44 at a cumulative IDA dosage of 322 mg/m2. The results of this study show that IDA is an active drug in elderly patients with advanced breast cancer. Due to its simplicity of administration IDA deserves further investigations in combination with other drugs.

Twenty-one adult patients with refractory solid tumors were treated on a phase I study of idarubicin (4-demethoxydaunorubicin) administered daily for 3 days every 3 weeks. Nineteen of the patients had received previous chemotherapy (including 13 with prior anthracyclines), and 12 had received prior radiotherapy. Idarubicin dose levels of 10, 15, 17.5, 20, and 25 mg/m2 were explored. Hematological toxicity was dose-related. Other toxicity was acceptable. Only one patient (treated with an idarubicin dose of 17.5 mg/m2/day) developed neutropenic fever, from which he recovered. Further dose escalations beyond 25 mg/m2 were not carried out because of the increasing length of time required for recovery from granulocytopenia at higher doses. No patient experienced a major response, but minor responses were seen in 3 patients with carcinomas of the colon, breast, and kidney respectively. Further phase II studies of oral idarubicin at a starting dose of 20-25 mg/m2 daily times 3 days in patients with good bone marrow reserves are recommended. Because of the degree of neutropenia expected, patients would have to be observed carefully.

Idarubicin (IDR) is a new anthracycline that can be administered orally. Oral IDR was given at a dose of 30 mg/m2 daily for 3 d in 20 patients aged 65 to 79 yr with previously untreated acute myeloid leukemia (AML). 5 patients whose marrow remained blastic at d 14 received a second course. 8 patients achieved complete remission (6 after one single course). There were: 1 early death, 4 deaths in aplasia, 7 failures. The hematologic toxicity was high. All but 1 patient had to stay in hospital and the duration of neutropenia was 12 to 34 d (median 19). Oral IDR is an effective therapy for AML in elderly patients but the total dose of 90 mg/m2 is too aggressive to be administered safely outside the hospital.

We report the results of a recent trial in elderly acute lymphoblastic leukemia (ALL) patients (> or = 60 years). Initial chemotherapy consisted of one 14-day course with single-dose idarubicin plus vincristine-prednisone-L-asparaginase. Idarubicin was preferred to other anthracyclines because of its shorter time to response. Sequential outpatient postremission therapy included single-dose idarubicin plus vincristine-cyclophosphamide-L-asparaginase pulses, cranial irradiation with intrathecal methotrexate-cytarabine, flexible weekly vincristine-cyclophosphamide alternating with cytarabine-teniposide, and two-year standard maintenance with mercaptopurine-methotrexate. Granulocyte colony-stimulating factor (G-CSF) was added to induction and early consolidation courses. Twenty-two patients mainly with high-risk features entered the study: median age was 64 years (60-73), 40% of cases were CD10- B-lineage and T-lineage ALL, 38% of CD10+ B-lineage ALL carried a BCR-ABL rearrangement, while 23% coexpressed myeloid antigen, 86% had L2 morphology, 50% had a blast count greater than 10 x 10(9)/1, 54% had hepato-splenomegaly and lymphadenopathy. The complete remission (CR) rate after induction therapy was 59%. A partial remission was obtained in two cases. There were four early deaths (18%) and three refractory ALL (14%). Median time to response was 21 days. With G-CSF, the median duration of absolute neutropenia was 10.5 days. Flexible postremission therapy was very well tolerated, causing no major toxicity. With a median follow-up of 2.6 years, 3 patients remain alive in first CR (23%), 2 of whom at 21.3 months and 39.6 months, respectively. Median survival of responders was 12 months compared to only 1.2 months for nonresponders (p < 0.001). This moderate-dose idarubicin-containing and G-CSF-supported regimen was associated with a high early remission rate in elderly ALL. Postremission therapy results were modest, though not appreciably different from the general experience in this patient population. Because further escalation of drug intensity appears unjustified, attempts to document and reverse drug resistance patterns and restore a dysregulated apoptosis must be considered.

Twenty three patients with relapsing (n = 11) or refractory (n = 12) non-Hodgkin's lymphoma (NHL) to one or two prior anthracycline based combination chemotherapy regimens were treated as second or third line regimen with 3 induction cycles of Idarubicin (IDA) (7 mg/m2/d i.v. d1-d3) and high dose cytarabine (HD Ara-C) (1 g/m2/12 h i.v. d1-d3), each cycle was repeated every 3 weeks. Responding patients received a maintenance therapy with monthly cycles of IDA: 15 mg/m2 d1-d3, Etoposide 100 mg/m2 d1-d3, both by oral route. Twenty two patients are evaluable and we observed 13 CR and 1 PR with an overall response rate of 61% (14/23: 95% Cl = 38.5% 80.3%). The median time to progression was 32 months (6.5 - 63 + m.). The response rate to IDA-HD Ara C was not different for patients with (n = 14) or without (n = 9) objective response to the last prior therapy. The main toxicity was hematological: all patients experienced grade 4 neutropenia and 22 patients had grade 4 thrombopenia, but there were no toxic deaths. IDA and HD-Ara-C combination is highly effective in refractory or relapsed. NHL. As hematological toxicity was the limiting factor for further escalation of dose-intensity, further studies might include hematopoietic growth factors support in the therapeutic scheme.

The GOELAM group conducted 2 consecutive trials on the treatment of de novo acute myeloblastic leukemia (AML) in adults. In the GOELAM1 protocol 786 patients aged 15-65 were randomized between two induction treatments (ARA-C 200 mg/m2/day for 7 days plus either Idarubicin 8 mg/m2/day for 5 days or Rubidazone 200 mg/m2/day for 4 days). Out of 731 evaluable patients, 521 (71%) achieved complete remission (CR) without significant difference between the 2 anthracyclines. For patients aged 51-65, the CR rate was significantly higher with Idarubicin (75%) than with Rubidazone (61%) (p = 0.03). In this group of patients the post-remission therapy consisted in only one course of high dose ARA-C plus m-Amsa and the 6 year disease free survival (DFS) was 24% (intention to treat analysis). For patients aged 15-50 years, the post remission therapy was either allogeneic bone marrow transplantation (BMT) (patients up to 40 years of age with an HLA identical sibling) or a first course of intensive consolidation chemotherapy (ICC) followed by a randomization between autologous unpurged bone marrow transplantation (ABMT) and a second course of ICC. There was no significant difference in the 4 year DFS between allogeneic BMT (42%) and the other types of intensive post remission-therapy (40%). The 4 year DFS was 42% for ABMT and 38% for ICC (p = 0.46) (intention to treat analysis). However the median duration of thrombocytopenia was much longer after ABMT (109.5 days versus 18.5 days p = 0.0001). The GOELAM SA3 randomized placebo-controlled protocol tested the impact of GM-CSF given during and after induction treatment for elderly patients (55-75 years). In this study, 232 evaluable patients received induction chemotherapy (Idarubicin 8 mg/m2/day for 5 days plus ARA-C 100 mg/m2/day for 7 days) plus placebo or GM-CSF 5 micrograms/kg/day from day 1 until the end of neutropenia. The CR rate was 61.5%. The median duration of neutropenia was shorter in the GM-CSF arm (22 days versus 27 days p = 0.0001). There was no overall significant advantage for the GM-CSF arm, in terms of CR rate and survival. However for patients age 55-64 the 2 year DFS was significantly higher in the GM-CSF arm (43% vs 17% p = 0.0013).

A 43-year-old female with a peripheral white cell count of 118.0 x 10(9)/L and 96% blasts was diagnosed with acute myeloid leukemia (AML), FAB M4. Cytogenetics, performed on a bone marrow sample, revealed the following abnormal karyotype: 46,XX,ins(16)(q22p13.1p13. 3). Fluorescence in situ hybridization (FISH) confirmed the inter-arm insertion using a probe for 16p. The result of this structural rearrangement was the fusion of CBF beta to MYH11 seen commonly in inv(16)(p13q22). The patient commenced high-dose intensive combination chemotherapy (big ICE; Idarubicin, Cytarabine, and Etopiside). Five days post chemotherapy, she developed febrile neutropenia. Despite broad spectrum intravenous antibiotics and antifungal therapy, the patient died at day nine post chemotherapy. This case demonstrates a previously unreported structural abnormality of chromosome 16 in a patient with AML M4, which represents a third mechanism to inv(16)(p13q22) and t(16;16)(p13q22) in producing the CBF beta-MYH11 fusion. CBF beta-MYH11 fusions masked by cryptic translocations at the cytogenetic level have been detected by FISH and PCR techniques. Due to the improved prognosis associated with CBF beta-MYH11 fusions compared to the standard risk group for AML, its detection remains important.

Idarubicin (IDR) is an anthracycline that can be administered orally. Low dose cytarabine (LDARAC) has been commonly used in the treatment of acute myeloid leukemia (AML) in elderly patients. A comination of oral IDR (20 mg/m(2) for 3 days) and LDARAC (10 mg/m(2) q12 hours for 10 days) was given in 32 patients aged 65 to 82 years (median 76) with de novo AML. Eight patients whose marrow remained blastic by day 20 received a second course (IDR for 2 days and LDARAC for 5 days). Complete remission (CR) was achieved in 13 cases (40.5%), (one course 12, two courses 1). There was 1 early death, 3 deaths in aplasia, 2 partial remissions and 13 failures. All but 5 patients were entirely managed in hospital. The median duration of neutropenia was 18 days and only 1 patient obtained CR without therapeutic aplasia. The extrahematologic toxicity was mild with 3 reversible cardiac events. These results are comparable to those obtained with conventional chemotherapy and this regimen could be proposed as induction treatment of AML in elderly patients.

Treatment of primary central nervous system lymphoma (PCNSL) in elderly patients remains unsatisfactory. To develop a new high-dose methotrexate (HD-MTX)-based regimen including idarubicin, a phase 1 multicenter dose escalation study was conducted to determine the maximum-tolerated dose (MTD) of idarubicin. Thirty-five immunocompetent patients with PCNSL were enrolled. The median age was 65 years (range, 60-70 years). MTX and vindesine (VDS) were given at the fixed dose of 3 g/m(2) (6-hr intravenous [IV]) and 3 mg/m(2) IV on day 1, respectively. Prednisolone (PRED) was given at the fixed dose of 60 mg/m(2) (IV or orally) on days 1-5. Idarubicin was escalated in increments of 2 mg/m(2) with doses ranging from 12-18 mg/m(2) IV on day 1. Treatment was repeated three times every 3 weeks. Dose-limiting toxicity (DLT) was defined as grade 4 neutropenia for more than 7 days, thrombocytopenia grade 4 or nonhaematological toxicity more than grade 2. The MTD of idarubicin was reached at 16 mg/m(2) . At this level, the main haematological toxicities were thrombocytopenia grade 4: 5% and neutropenia grade 3 or 4 (52%); the main nonhaematological toxicities were grade 3 or 4 infectious disease (5%) and grade 2 renal failure (9%). For the study population, median overall and progression-free survival were 19 and 13 months, respectively. Our study suggests that the MTD of idarubicin in combination with HD-MTX, VDS, and PRED, should be 16 mg/m(2) . Further studies will be necessary to challenge a standard treatment in elderly patients with PCNSL.
