Intensive remission induction therapy for chronic myeloid leukemia in blast phase with a goal of post-remission bone marrow transplant--a pilot study.

An intensive protocol utilizing mitoxantrone, high-dose cytarabine, vincristine, etoposide and methylprednisolone as induction therapy for chronic myeloid leukemia in blast transformation is described. Fourteen patients were treated, with a remission/second chronic phase achieved in 64%. None of the 3 patients older than 50 yr responded. Complete hematological responses were seen in 9 of the 11 younger patients, 4 of whom also became BCR-ABL negative by Southern Blot analysis. Four patients went on to allogeneic bone marrow transplant. Median remission durations were 4.5 (1-5) and 8.5 (5-16) months in the non-transplanted and transplanted cohorts, respectively. Median survival is 1.5 (0.5-3), 9.5 (7-14) and 17 (14-61+) months in the non-responding, responding non-transplanted and transplanted cohorts, respectively. Toxicity, particularly gastrointestinal, was significant. This represents an aggressive protocol that should be reserved for patients who are potential transplant candidates.

[AML-6 and AML-7 studies on the treatment of acute myelocytic leukemia. Cyclic alternating chemotherapy during remission, and induction of remission and survival of elderly patients].

Twenty-five institutions are participating in the AML-6-trial designed to improve remission incidence and to delay the time of relapse. Therefore, an intensive cyclic therapy is employed early after achievement of remission using either the same drugs of the induction regimen or rotating combinations of alternative drugs, e.g. AMSA, 5-AZA and HD-araC. So far, 266 patients entered the trial. The overall C.R. rate is 71%. 58 patients are randomized to 'maintenance' arm I, 54 to arm II, 79/112 patients are still being studied. Toxicity was in 7% and 3% respectively a reason to interrupt the study during induction or 'maintenance'. Since the intensity of modern protocols for remission induction of AML presents a major problem in elderly patients due to toxicity, and since most studies indicate low remission rates with an increasing death rate in this age group, the AML-7-study was initiated to prospectively compare survival and quality of life of two different therapeutic strategies: immediate intensive remission induction versus supportive care, 'wait and see' policy, and palliative cytoreduction with hydroxyurea and ara C when necessary. During the first 8 months after activating this study, 27 patients entered, 13 were randomized to branch I, and 14 to branch II.

Remission induction therapy for adults with acute myelogenous leukemia: towards the ICE age?

The primary goal of acute myeloid leukemia chemotherapy is to obtain a complete remission. In adults with de novo disease, response rates reach between sixty and seventy per cent with classical '3 + 7' or DAT schemes. Curative postinduction treatments are now available for responsive patients, which makes it mandatory to look for more effective modalities of induction therapy. Experience gathered in recent years shows that idarubicin, cytosine arabinoside, and etoposide together might contribute to the modeling of an improved remission induction regimen: ICE. Because ICE and similar programs are being used with increasing frequency worldwide, we decided to review critically the underlying issues and the evidence supporting this change.

Bone marrow transplantation or chemotherapy after remission induction for adults with acute nonlymphoblastic leukemia. A prospective comparison.

We compared the outcome of marrow transplantation with that of continued chemotherapy for adults with acute nonlymphoblastic leukemia who achieve a first remission. From May 1977 to July 1982, 111 consecutive adults (ages 17 to 50) with newly diagnosed acute nonlymphoblastic leukemia were treated with induction chemotherapy. Ninety patients (81%) had a complete remission. Forty-four remission patients had available donors: 33 received a transplant and 11 did not. Forty-six patients in remission without matched donors were treated with continued chemotherapy. Kaplan-Meier estimates of 5-year, disease-free survival from complete remission are 49% +/- 18% for the transplant group and 20% +/- 13% for the chemotherapy group. When compared to the chemotherapy group, patients undergoing transplantation had a higher risk of dying during the first 6 months after remission induction but a lower risk of dying thereafter. Within the transplant group, only age influenced survival. Within the chemotherapy group, a leukocyte count of greater than 10 000 mm3 at diagnosis, a French-American-British (FAB) Cooperative Group morphologic status of M-4, M-5, or M-6, and the presence of infection at diagnosis were all associated with shorter survival.

High-dose methylprednisolone for remission induction in children with acute nonlymphoblastic leukemia.

The effectiveness of high-dose intravenous methylprednisolone (HIVMP) in inducing an initial remission was examined in a child with acute nonlymphoblastic leukemia (ANLL). Dramatic clinical and hematological improvement with 7% marrow blasts was obtained in 3 weeks with HIVMP treatment without giving any other antileukemic drugs. Based on the results of this preliminary observation we suggest that high-dose methylprednisolone (20-30 mg/kg) might be a useful approach when applied as an initial short treatment in childhood ANLL.

Recombinant human interleukin-3 (rH IL-3) in combination with remission induction chemotherapy in patients with relapsed acute myelogenous leukemia (AML): a phase I/II study.

Patients with AML who relapse after an initial remission, have a poor prognosis. Administration of hemopoietic growth factors (HGFs) such as interleukin-3 (IL-3) during chemotherapy may result in an increased cell kill by cytotoxic agents. In addition, administration of IL-3 following chemotherapy may potentially accelerate hemopoietic recovery from chemotherapy-induced bone marrow hypoplasia. We performed an open labelled, phase I/II study in which patients received IL-3 by continuous infusion from 24 h before the beginning of chemotherapy until day 28. Chemotherapy included daunorubicin or mitoxantrone days 1-3 and cytarabine 200 mg/m2 days 1-7. IL-3 was given at a dose of 5 microgram(s)/kg/day in 10 patients, 7.5 microgram(s)/kg /day in six patients and 10 microgram(s)/kg/day in four patients. Complete remissions (CR) after one cycle of this treatment were obtained in 5/10 patients and 5 microgram(s)/ kg group, 2/6 in the 7.5 microgram(s)/kg group and 3/4 in the 10 microgram(s)/kg group). Thus, 50% (10/20) of all individuals and 45% (5/11) of the elderly patients attained CR. Eight of 20 patients entered PR, and 2/20 patients died during the hypoplastic phase from infectious complications. Neutrophils and platelets recovered to 0.5 x 10(9)/l at day 25 (median) and to 50 x 10(9)/l at day 32, respectively. Adverse events during IL-3 and concomitant chemotherapy were fluid retention (4/20), rash (14/20), bone pain (2/20), headache (10/20), chest pain (1/20), arthritis (1/20), fever and nausea. IL-3 (at the dose of 10 microgram(s)/kg) was discontinued in two patients because of side-effects (fluid retention, fever, rash and chest pain), and in two other patients the high IL-3 dose was tolerated with no problems for 29 days. Thus, IL-3 applied to patients with high-risk AML at dosages of 5-10 microgram(s)/kg is tolerated with acceptable toxicity and results in a satisfactory frequency of complete responses following a single treatment cycle.

[Differentiation therapy of acute promyelocytic leukemia: two successful cases of remission induction by all-trans retinoic acid].

We described two pediatric patients with acute promyelocytic leukemia (APL) who were successfully induced into complete remission with all-trans retinoic acid (ATRA, 45 mg/m2 per day) after failing on conventional chemotherapy. Initial response was observed as correction of DIC within a week of treatment. Hematologically, initial increase of maturing leukocytes reached a peak peripheral WBC count on the 16th and 20th day, respectively. However, these seemingly differentiated leukocytes retained Auer body and dysplastic features and there was no concomitant recovery of erythroid and megakaryocytic lineages at this point. A sudden drop of leukocyte counts after this peak made a brief period of leukopenia before the complete remission was finally attained morphologically in 4-5 weeks. Thus, remission of APL by ATRA therapy consisted of a two-phase course. In one patient, we observed an increase of histiocytes phagocytizing leukocytes in the marrow during the recovery from leukopenia. It is, therefore, postulated that the two-phase course of recovery may reflect the differentiation of leukemic cells by ATRA and subsequent clearance of senescent cells by the reticuloendothelial system followed by regeneration and differentiation of residual normal hematopoietic stem cells.

Idarubicin (4-demethoxydaunorubicin) as single agent for remission induction of previously untreated acute promyelocytic leukemia: a pilot study of the Italian cooperative group GIMEMA.

Because of the reported high sensitivity of acute promyelocytic leukemia to daunorubicin, we treated 27 consecutive, newly diagnosed, acute promyelocytic leukemia (APL) patients with the new anthracycline idarubicin (IDA) as induction therapy. IDA dosage ranged from 0.25 to 0.30 mg/kg/day and the drug was administered as single agent during a single induction course of 6 days. A total of 22/27 patients (81%) achieved complete remission, 4 (15%) died during induction and 1 patient was resistant to IDA. Extrahematological toxicity was acceptable. A total of 13/22 patients having achieved CR are still alive and in first CR after a median follow-up of 12 months. As for the treatment of the coagulopathy present in APL: 17/27 (63%) received tranexamic acid (6 g/daily) in continuous infusion for total of 7 d. None of the patients treated with tranexamic acid experienced thromboembolic complications. In conclusion, this multicentric pilot study confirms the antileukemic potency of IDA and the high sensitivity of APL to anthracycline derivatives.

Determinants of complete remission induction and maintenance in chemotherapy with or without irradiation of small cell lung cancer.

The possible influence of pretreatment patient characteristics upon the probabilities of complete remission (CR) induction and maintenance was investigated in a series of 815 nonresected patients with small cell lung cancer. All patients underwent pretreatment staging which enabled allocation of 391 patients to trials for limited stage disease and 424 patients to trials for extensive disease. Three controlled trials for each disease stage were conducted between 1973 and 1981. All therapeutic regimens consisted of combinations of between three and six agents (lomustine, cyclophosphamide, methotrexate, vincristine, doxorubicin, etoposide) with or without irradiation. Thirty-five % of the limited stage patients and 18% of the extensive stage patients were alive and had achieved a complete remission 16 weeks after initiation of the treatment, i.e., after four cycles of chemotherapy. Relationships between pretreatment characteristics and the probability to pass this benchmark were examined by logistic regression analysis. The probability of CR was negatively related to increased serum lactate dehydrogenase and male sex in both disease stages. Pretreatment anemia (less than 12 g/liter) and poor performance status were associated with a reduced CR rate in limited and extensive stage disease, respectively. Factors related to the maintenance of complete remission were subsequently examined in the 211 complete responders by use of Cox's regression analysis. Complete responders with extensive disease prior to treatment had greater cumulative risk of relapse than those with limited disease (P less than 0.01). Hyponatremia had a significant negative influence on the remission duration in limited disease while age greater than 60 years and bone marrow metastases had significantly negative influence in extensive disease. Using the models it was possible to identify subgroups of patients with CR rates ranging from 5 to 55% and to stratify complete responders according to estimated risks of subsequent relapse.

Early intensification of chemotherapy for childhood acute nonlymphoblastic leukemia: improved remission induction with a five-drug regimen including etoposide.

We tested the value of early intensification of chemotherapy in 68 consecutive children with acute nonlymphocytic leukemia (ANLL) who were admitted to St. Jude Children's Research Hospital from November 1983 through March 1987. Fifty-eight patients (85%) entered complete remission after treatment with etoposide (VP-16)/cytarabine (ara-C) (A), followed by daunorubicin (Dauno)/ara-C/thioguanine (6-TG) (B) and then VP-16/azacytidine (5-AZ) (C). Thirty percent of the complete responders, mainly those with an M4 or M5 leukemia subtype, attained M1 marrow status after component A, 60% after A + B, and 10% after A + B + C. Induction failures resulted primarily from absolute or relative drug resistance; there was only one death during this phase of therapy. Postremission treatment consisted of three pairs of drugs (vincristine [VCR]/amsacrine [m-AMSA], or doxorubicin [Doxo]/6-TG/ara-C, and VP-16/cyclophosphamide [CTX]) administered sequentially in 6-week cycles for 22 months. Despite the high rate of remission induction, only 33% +/- 7% SE of the patients are expected to be failure-free survivors at 2 years. Remission durations were not significantly affected by the majority of factors examined in this study, with the exception of marrow cellularity after VP-16/ara-C induction therapy. Patients with less than or equal to 5% leukemic cells survived relapse-free for a median of 36.1 months, compared with 11.3 months for the group with a larger infiltrate (P = .01). Although postremission therapy did not improve the percentage of long-term failure-free survivors, the induction regimen we used appears highly effective, and its components should be considered for inclusion in other treatment programs.

Non-anthracycline based remission induction therapy for newly diagnosed patients with acute myeloid leukemia aged 60 or older.

We assessed remission rates and toxicity in 24 consecutive elderly (age>or=60) patients with untreated Acute myeloid leukemia (AML) who received the anthracycline-free combination of fludarabine, cytosine arabinoside and G-CSF (FLAG) as initial induction chemotherapy at our center. CR was achieved following one cycle of FLAG in 14 patients (58%). Another four patients cleared blasts from their bone marrow by day 30 without complete platelet recovery. Three patients died from infections prior to neutrophil recovery (12%). No other grade 3/4 toxicities and no clinically significant mucositis were seen. No significant association was found between age, WBC and cytogenetic risk group with likelihood of achieving CR. Fifteen patients proceeded to consolidation therapy and seven patients received a stem cell transplant (six autologous, one allogeneic). Primary induction with FLAG in elderly AML patients achieves a high remission rate without prohibitive mucosal or cardiac toxicity and may thus be considered as an alternative to standard anthracycline-based regimens in this setting.

Remission induction in refractory Crohns disease using a high calorie whole diet.

Eleven patients with severe refractory Crohns disease were treated with a high calorie, whole diet. Eight patients achieved remission with a drop in DAS from 13 to 4 (t = 6.31, p less than 0.001) and reversal of subacute obstruction in all cases. Nutritional parameters including weight, triceps skinfold thickness, arm muscle area, and serum albumin increased in all patients. The diet was well tolerated with a mean treatment period of 20 days. Clinical relapse of disease occurred in all cases within 9 months (mean 6 +/- 2 months). The mechanism of action of a high calorie diet (HCD) is unclear and warrants further study but antigen or specific food exclusion does not appear to be required as judged by this study.

Treatment of acute myelogenous leukaemia in patients aged 50-65: idarubicin is more effective than zorubicin for remission induction and prolonged disease-free survival can be obtained using a unique consolidation course. The Goelam Group.

From December 1987 to June 1992, 251 patients aged 50-65 with de novo acute myelogenous leukaemia (AML) were recruited to a multi-institutional randomized clinical trial. Induction therapy consisted of Ara-C (200 mg/ m2, continuous infusion, days 1-7) with either zorubicin (ZRB) (200 mg/m2, i.v., days 1-4) or idarubicin (IDR) (8 mg/ m2, i.v., days 1-5). Consolidation therapy consisted of a single course of intensive chemotherapy with high-dose Ara-C (3 g/m2, 3 h infusion, q 12 h, days 1-4) and m-Amsa (100 mg/m2/d, i.v., days 5-7). The complete remission (CR) rate was (73%) with Ara-C/ IDR versus (60%) with Ara-C/ZRB (P = 0.033). In multivariate analysis, factors found to be significant in predicting CR were normal karyotype and treatment with IDR. With a median follow-up of 73 months, the median disease-free survival (DFS) duration of all CR patients and the probability of CR at 6 years were 17 months and 29%. In multivariate analysis the only factor associated with an increased DFS duration was a normal karyotype. The median event-free survival (EFS) duration for all evaluable patients and the median overall survival duration for all eligible patients were respectively 7 and 12 months without any difference between induction arms. The study shows that in patients aged 50-65 idarabicin is more effective than zorubicin for remission induction. However, the type of anthracycline did not influence overall survival duration. Using a unique consolidation course, we observed a prolonged DFS which compares favourably with results obtained with more prolonged consolidation therapy or maintenance treatment.

Remission induction in a Jehovah's witness patient with acute myeloid leukaemia using gemtuzumab ozogamicin.

A 40-year-old patient, who was a Jehovah's Witness, with acute myeloid leukaemia entered remission using a chemotherapeutic based regime aided by the addition of gemtuzumab ozogamicin without requiring any blood product support. The use of gemtuzumab ozogamicin may have helped avoid fatal pancytopenia. The use of gemtuzumab ozogamicin might be considered in similar situations.
