Ten patients with acute leukemia (AL) in early relapse after allo-BMT were treated with a modified MEC (mitoxantrone, etoposide and Ara-C) regimen followed by donor PBPC collected after mobilization with G-CSF. Seven patients achieved CR or had normal hemopoietic reconstitution: two had an early relapse at days +53 and +48, two patients died from acute GVHD at days +31 and +96, one died of interstitial pneumonia at day +55, and two patients experienced long-term survival. One patient with refractory disease and nodal involvement who did not respond to the first BMT had overt expansion of the leukemia at day +36; one patient with Ph+ ALL and one with ANLL evolving from MDS, both with skin involvement, had blast cells in peripheral blood at day +27 and +26, respectively. Transient cytopenia occurred in all patients; a normal granulocyte and platelet count was achieved within 3 weeks in all patients but one; acute GVHD occurred in six patients, and four had chronic GVHD. This approach is feasible in patients in early relapse after allo-BMT. It assists prompt re-establishment of normal donor hematopoiesis avoiding the prolonged cytopenia observed after donor lymphocyte infusion in AL patients relapsed after allo-BMT.

Allogeneic transplantation is a well recognized treatment strategy of leukemia. However, its use in advanced leukemia patients is a subject of some debate especially when donors are not HLA-identical siblings because of the toxicity and cost of the procedure. We reviewed retrospectively the outcome of patients (pts) who received allogeneic transplantation for advanced acute leukemia in our center between 09/86 and 11/97. Thirty-six pts (study group) who lacked a matched sibling donor received partially matched related donor (n=14: PMRD group) or matched unrelated donor transplantation (n=22: MUD group). Fifteen pts had AML and 21 ALL. Seventeen pts (47%) were in CR>1, 13 pts (36%) had refractory disease and six pts (17.7%) were in untreated relapse. The outcome was compared to that of 56 patients (AML: 45.5 %, ALL: 55.5 %, CR>1: 49.9 %, refractory disease: 37.5 %, untreated relapse 19.6 %) who received allogeneic transplantation from a matched sibling donor (control group). Various conditioning regimens and GVHD prophylaxis were used. The actuarial incidence of grade II to IV acute GVHD was significantly higher in the study group (57%) than in the control group (34%) (p=0.047). The actuarial risk of relapse at three years was 21% +/- 22% in the study group versus 65% +/- 16% in the control group (p= 0.04). The actuarial probability of transplant-related mortality at 3 years is 64 +/- 16% for the study group and 25 +/- 11% for the control group (p=0.001). The leading cause of death in the study group was infection (30%) followed by acute GVHD and relapse. Relapse was the major cause of death in the control group (54%), followed by infection, interstitial pneumonia, veno-occlusive disease and GVHD. The OS and probability of leukemia-free survival at 3 years were 28 % +/- 15% (95% CI) and 27% +/- 15% (95% CI) in the study group. The overall survival and probability of LFS at 3 years were respectively 28 +/- 12% (95% CI) and 23 +/- 12% (95% CI) in the control group (p = 0.08 and p=0.11 respectively). In multivariate analysis, transplant-related mortality was higher in the study group (p=0.04) and lower if both donor and recipient were seronegative for CMV (p=0.007). OS was significantly higher for seronegative couples (p=0.0001), and when CR was achieved before BMT (p=0.0022). These results suggest that all efforts in this field should be directed on lowering the transplant related mortality for non geno-identical transplants and the relapse rate in geno-identical transplants.

The aim of the study was to compare the therapeutic efficacy of total body irradiation (TBI)/cyclophosphamide (CY) versus BU/CY as conditioning regimen for leukemia. We electronically searched the Cochrane Central Register of Controlled Trials, Medline, Embase, CIBMTR and critically appraised all relevant articles (1990.01-2009.04). Comparative studies were evaluated on clinical therapeutic effects of TBI/CY and busulphan BU/CY regimens with assessement of engraftment, relapse, complications, and disease-free survival (DFS). Eighteen trials totaling 3172 patients have been assessed. Pooled comparisons of studies indicated that for patients with acute leukemia (ALL and AML), the TBI/CY regimen lead to lower rates of leukemia relapse, lower transplant-related mortality (TRM), and higher DFS, while for chronic myeloid leukemia (CML), the TBI/CY regimen had a higher rate of leukemia relapse, lower TRM, and similar DFS. The TBI/CY regimen was associated with similar occurrence of engraftment, acute and chronic graft-versus-host disease (GVHD), but with higher rates of cataract [odds ratio (OR) 12.69, p = 0.01], interstitial pneumonitis, later growth or development problems [OR 5.04, p = 0.008]. BU/CY regimen was associated with higher rates of complications like liver veno-occlusive disease [OR 0.43, p < 0.00001], hemorrhagic cystitis, and TRM. Our meta-analysis confirmed that different regimens and type of leukemia may affect the complications and outcome. An analysis of the effects of other regimens need to be carried out by large sample and well-designed clinical trials.

Idiopathic pulmonary fibrosis (IPF) is a high risk factor for acute exacerbation of interstitial pneumonia (IP) after pulmonary resection. Other risk factors for inducing IP exacerbation are thought to be intraoperative inhalation of high concentration of oxygen, high pressure mechanical ventilation, major thoracic surgery, massive blood transfusion and preoperative chemotherapy and irradiation. The prophylactic strategy for this phenomenon has not been established, although mechanical ventilation by low pressure and low oxygen concentration, minimum invasive surgery and prophylactic administration of steroid, ulinastatin and sivelestat sodium hydride are performed. Acute exacerbation of IP is the same concept with acute lung injury (ALI)/acute respiratory distress syndrome (ARDS). This pulmonary injury is closely associated with reactive oxygen species (ROS). In particular, high concentration of oxygen induces excessive production of ROS. ROS stimulates alveolar macrophages and neutrophils to release inflammatory cytokines, such as TNF-alpha, IL-8, IFN-gamma, IL-6 and IL-1beta. These cytokines injure pulmonary endothelium and alveolus, and atelectasis, pulmonary hemorrhage, lung edema, hyalinization and alveolar thickness occur, and this is a manifestation of ALL Therefore, although there is no evidence, high pressure ventilation and inhalation of high oxygen concentration during anesthesia should be avoided.
