Preemptive therapy is the standard strategy for preventing CMV disease after allogeneic hematopoietic SCT. In this study, unrelated BMT recipients were randomly assigned to a plasma real-time PCR group or an antigenemia group to compare the value of these monitoring tools for CMV reactivation. Ganciclovir (GCV) was started at 5 mg/kg/day when PCR reached 300 copies per ml or when antigenemia reached three positive cells per two slides. A total of 88 patients were randomized into the antigenemia group (n45) or the PCR group (n43). A significantly higher number of patients reached the threshold in the antigenemia group than in the PCR group (73.3 vs 44.2%, P0.0089). However, only three patients (one in the antigenemia group and two in the PCR group) developed early CMV disease. These patients exclusively had colitis and were successfully treated with GCV or foscarnet. The median number of antigenemia-positive cells at the start of GCV was 47 in the PCR group. These findings suggest that antigenemia assay with the current cutoff was too sensitive and led to unnecessary use of GCV. However, the appropriateness of the threshold may be different by the methodology used, and therefore, it is difficult to generalize. © 2010 Macmillan Publishers Limited All rights reserved. Source

Background: Human immunodeficiency virus (HIV)-infected patients are surviving longer since the advent of antiretroviral therapy. Therefore, more patients are developing non-AIDS-defining cancers which increasingly determine mortality. Case Reports: Here we present 2 cases of locally advanced non-small cell lung cancer treated initially with concomitant chemoradiotherapy and antiretroviral therapy. Both patients were male, ages 69 and 66, with known HIV infection and immunologically stable on antiretroviral therapy. Presenting symptoms included superior sulcus tumor with left arm immobility and sensory disturbance in case 1 and right lower bronchus constriction in case 2. Symptoms were controlled by chemoradiotherapy. Conclusion: These cases illustrate that intensive anticancer therapy administered to the HIV-infected population can be tolerated even though these patients seem to be too fragile for both chemotherapy and radiotherapy, especially since the potential benefit remains uncertain. Recent improvements in chemoradiotherapy and supportive care have enhanced tolerance for such therapy. © 2013 S. Karger GmbH, Freiburg. Source

Background and Aims: Bleeding is a major complication after gastric endoscopic submucosal dissection (ESD). An evidence-based strategy for postoperative care related to delayed bleeding is required. We conducted a multicenter survey to assess the current status of management after gastric ESD. Methods: A total of 1,814 gastric epithelial neoplasms in 2009 at ten tertiary referral centers were enrolled. The current status of the management after gastric ESD (use of an antisecretory drug, food intake, and second-look endoscopy) at participating hospitals was assessed. Furthermore, the rate of post-ESD bleeding and the differences in each parameter were retrospectively analyzed. Results: Postoperative bleeding occurred in 100 cases (5.5%), which included 62 cases of bleeding within 24 h after ESD. In all of the hospitals, proton pump inhibitors (PPIs) were used. The median administration period was 56 days (range 14-60 days). Food intake was resumed from postoperative day (POD) 1 in 4 hospitals and from POD 2 in 6 hospitals. Second-look endoscopy was performed for almost all cases, fewer cases, and rarely or none in 6, 2, and 2 hospitals, respectively. The day of second-look endoscopy varied among hospitals. There was no statistical relationship between the postoperative bleeding rate and the differences in these three parameters. Conclusions: Post-ESD management (duration of PPI use, resumption of food intake, and performance of second-look endoscopy) varied among the medical centers; thus, randomized controlled trials are required for an optimal strategy after gastric ESD. © 2011 Springer Science+Business Media, LLC.

To elucidate the impact of pretransplant body mass index (BMI) on the clinical outcome, we performed a retrospective study with registry data including a total of 12 050 patients (age ≥18 years) who received allogeneic hematopoietic SCT (HSCT) between 2000 and 2010. Patients were stratified as follows: BMI<18.5 kg/m 2, Underweight, n=1791; 18.5≤BMI<25, Normal, n=8444; 25≤BMI<30, Overweight, n=1591; BMI≥30, Obese, n=224. The median age was 45 years (range, 18-77). A multivariate analysis showed that the risk of relapse was significantly higher in the underweight group and lower in the overweight and obese groups compared with the normal group (hazard ratio (HR), 1.16, 0.86, and 0.74, respectively). The risk of GVHD was significantly higher in the overweight group compared with the normal group. The risk of non-relapse mortality (NRM) was significantly higher in the overweight and obese group compared with the normal group (HR 1.19 and HR 1.43, respectively). The probability of OS was lower in the underweight group compared with the normal group (HR 1.10, P=0.018). In conclusion, pretransplant BMI affected the risk of relapse and NRM after allogeneic HSCT. Underweight was a risk factor for poor OS because of an increased risk of relapse. Obesity was a risk factor for NRM. © 2014 Macmillan Publishers Limited. Source

Leukemia | Year: 2011

Clinical studies using genetic randomization cannot accurately answer whether adult patients with Philadelphia chromosome-negative acute lymphoblastic leukemia (ALL) who have a human leukocyte antigen (HLA)-matched sibling should undergo allogeneic hematopoietic stem cell transplantation (HSCT) or chemotherapy in first remission, as, in these studies, patients without a sibling donor undergo alternative donor transplantation or chemotherapy alone after a relapse. Therefore, we performed a decision analysis to identify the optimal strategy in this setting. Transition probabilities and utilities were estimated from prospective studies of the Japan Adult Leukemia Study Group, the database of the Japan Society for Hematopoietic Cell Transplantation and the literature. The primary outcome measure was the 10-year survival probability with or without quality of life (QOL) adjustments. Subgroup analyses were performed according to risk stratification on the basis of white blood cell count and cytogenetics, and according to age stratification. In analyses without QOL adjustments, allogeneic HSCT in first remission was superior in the whole population (48.3 vs 32.6%) and in all subgroups. With QOL adjustments, a similar tendency was conserved (44.9 vs 31.7% in the whole population). To improve the probability of long-term survival, allogeneic HSCT in first remission is recommended for patients who have an HLA-matched sibling. © 2011 Macmillan Publishers Limited All rights reserved.
