The main limitations of transplantation of bone marrow from donors who are matched with the recipient for only one HLA haplotype GVHD and graft failure - can be overcome. Since most patients have a relative with one haplotype mismatch, advances in this method will increase the availability of hematopoietic-cell transplantation as curative therapy for acute leukemia.

To evaluate the efficacy and safety of itraconazole oral solution for preventing fungal infections, a randomized, placebo-controlled, double-blind, multicenter trial was conducted: 405 neutropenic patients with hematologic malignancies were randomly assigned to receive either itraconazole, 2.5 mg/kg every 12 hours (201 patients), or placebo (204 patients). Proven and suspected deep fungal infection occurred in 24% of itraconazole recipients and in 33% of placebo recipients, a difference of 9 percentage points (95% confidence interval [CI], 0.6% to 22.5%; P = .035). Fungemia due to Candida species was documented in 0.5% of itraconazole recipients and in 4% of placebo recipients, a difference of 3.5 percentage points (95% CI, 0.5% to 6%; P = .01). Deaths due to candidemia occurred in none of the itraconazole recipients compared with 4 placebo recipients, a difference of 2 percentage points (95% CI, 0.05% to 4%; P = .06). Aspergillus infection was documented in four itraconazole recipients (one death) and one placebo recipient (one death). Side effects causing drug interruption occurred in 18% of itraconazole recipients and 13% of placebo recipients. Itraconazole oral solution was well-tolerated and effectively prevented proven and suspected deep fungal infection as well as systemic infection and death due to Candida species.

Hospitalization and empirical broad-spectrum, intravenous antibiotics are the standard treatment for febrile cancer patients. Recent evidence supports the suggestion that febrile episodes in a low-risk population can be managed successfully in an outpatient setting, but the optimal drug regimen is unknown. In a prospective randomized clinical trial we compared ciprofloxacin 750 mg p.o. twice a day with ceftriaxone 2 g i.v. as a single daily dose for the empiric domiciliary treatment of febrile episodes in low-risk neutropenic and nonneutropenic cancer patients. A total of 173 patients, accounting for 183 febrile episodes, were enrolled in the study. Overall, successful outcomes were recorded for 76 of 93 (82%) febrile episodes in patients who were randomized to the oral regimen and for 68 of 90 (75%) febrile episodes in patients randomized to the i.v. regimen: this difference was not statistically significant. The success rate was similar in all subgroups of patients: neutropenic and nonneutropenic, with documented infection and with fever of unknown origin. There were 3 deaths in the group of patients treated with the parenteral regimen, and two of these were related to treatment failure. Both treatments were well tolerated, and the cost of the oral regimen was lower. This prospective study suggests that domiciliary antibiotic empiric monotherapy is feasible in febrile nonneutropenic or low-risk neutropenic outpatients in whom a bacterial infection is suspected, and that either an oral or a parenteral regimen can be used. A number of factors may influence the choice between an orally and an i.v.-administered antibiotic, but owing to the easier administration and lower cost, the oral regimen seems to be preferable.
