A randomized trial of induction therapy (daunorubicin, vincristine, prednisone versus daunorubicin, vincristine, prednisone, cytarabine and 6-thioguanine) in adult acute lymphoblastic leukemia with long-term follow-up: an Eastern Cooperative Oncology Group Study (E3486).

In this study of previously untreated adult acute lymphocytic leukemia (ALL) performed by the Eastern Cooperative Oncology Group, patients were randomized to induction therapy with either DVP (daunorubicin 45 mg/m2 daily, days 1, 2 and 3; prednisone 60 mg/m2 daily orally days 1-35; and vincristine 2 mg intravenously on days 1, 8, 15 and 22) or DATVP (daunorubicin 60 mg/m2 daily, days 1, 2 and 3; cytarabine 25 mg/m2 intravenous bolus followed by 200 mg/m2 daily as a continuous infusion on days 1-5; 6-thioguanine 100 mg/m2 orally every 12 h on days 1-5; vincristine 2 mg intravenously on days 1 and 8; and prednisone 60 mg/m2/day orally, days 1-7. Complete responders to both regimens received the same post-remission therapy, which consisted of a single course of cytarabine 3 gm/m2 infused over 1 h every 12 h for 12 doses. One month later those patients still in remission received six cycles of consolidation therapy with MACHO (cyclophosphamide 650 mg/m2, doxorubicin 40 mg/m2 vincristine 2mg all intravenously on day 1 with prednisone 100 mg/m2 orally daily on days 1-5. Methotrexate 200 mg/m2 intravenously and L-asparaginase 6000 U/m2 were given on day 22 and each course was given every 5 weeks. A single dose of intrathecal methotrexate was also given with each MACHO course. There were 276 evaluable patients randomized in this study. Complete response rates were 71% for DVP and 58% for DATVP. Median durations of complete response were 5.5 and 6.8 months, respectively. Median survival of all randomized patients was 14.4 months in each group. DATVP was more toxic than DVP. Intensification of treatment for adults with ALL may not improve outcome. Progress in the treatment of adults with ALL will require the identification of new agents for this neoplasm.

Neutropenic colitis after treatment of acute myelogenous leukemia with idarubicin and cytosine arabinoside.

OBJECTIVE: To determine the gastrointestinal toxic effects of idarubicin and cytosine arabinoside combination therapy in patients with newly diagnosed acute myelogenous leukemia (AML). PATIENTS AND METHODS: We performed a single-institution retrospective analysis of the incidence of neutropenic colitis in patients with newly diagnosed AML receiving idarubicin and cytosine arabinoside combination therapy. Using pharmacy records, we identified 78 patients who received idarubicin during the study period of January 1997 to September 1998 and who agreed to a review of their medical records. Patients with preexisting bowel conditions were excluded from this analysis. We used a strict definition of neutropenic colitis that included clinical findings (severe abdominal pain, diarrhea, hematochezia, and/or peritoneal signs) plus radiographic evidence of bowel inflammation in the absence of an identified bacterial pathogen. RESULTS: Of the 78 patients receiving idarubicin and cytosine arabinoside for treatment of AML, 65 were included in this study. We observed neutropenic colitis in 10 of these 65 AML patients. This complication was followed by sepsis in 3 patients and was the major cause of death in 4 of the 8 patients who died. CONCLUSION: This analysis suggests that neutropenic colitis is a frequent and serious complication of idarubicin and cytosine arabinoside treatment.

Veno-occlusive disease of the liver after blood and marrow transplantation: analysis of pre- and post-transplant risk factors associated with severity and results of therapy with tissue plasminogen activator.

We reviewed our blood and marrow transplantation (BMT) database from April 1982 to July 1996 and identified 111 of 474 patients with serum bilirubin concentration (SBR) > or = 34 micromol/l for two consecutive days within the first 20 days after related allogeneic or autologous BMT. Of the 111, 73 fulfilled the Seattle criteria for veno-occlusive disease of the liver (VOD) and had no other obvious cause for liver dysfunction. The patients were 16-60 years old (median, 39 years), and 41 were male (56%). Fourteen patients (19%) had autologous BMT, and 59 (81%) had allogeneic BMT. Twenty-eight (38%), 12 (16%), and 33 (45%) patients had severe, moderate, and mild VOD, respectively, by Seattle criteria. None of 23 patients with maximum (max) SBR > or = 257 micromol/l survived, all patients with max SBR < or = 128 micromol/l survived, and 7 of 15 patients (47%) with max SBR 128-257 micromol/l survived. The only pre-transplantation risk factor predictive of severe VOD was advanced disease state (P = 0.035), and the only transplant factors that predicted severe VOD were max SBR (P = 0.01) and maximum blood urea level (P = 0.03). Ten patients (all with creatinine levels > or = 150 micromol/l) were treated with tissue plasminogen activator; only two had a significant response and only one survived beyond day 120.
