ABSTRACT
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a currative treatment modality for diffuse large B-cell lymphoma (DLBCL) because of the intrinsic graft-versus-lymphoma effect. However, limited information is available regarding which patients with relapsed or refractory DLBCL are likely to benefit from allo-HSCT. We retrospectively analyzed data from 1268 DLBCL patients who received allo-HSCT. The overall survival and progression-free survival (PFS) rates were 30.3% and 21.6% at 3 years, respectively. Multivariate analysis revealed that stable or progressive disease at transplantation, male patient, poorer performance status at transplantation, and shorter intervals from previous transplantation were associated independently with a lower PFS. Four prognostic factors were used to construct a prognostic index for PFS, predicting 3-year PFS of 55.4%, 43.7%, 20.4% and 6.6%, respectively. The prognostic model predicted relapse rates following allo-HSCT accordingly (P < 0.0001), whereas did not predict transplantation-related mortality (P = 0.249). The prognostic index can identify a subgroup of DLBCL patients who benefit from allo-HSCT and it is worthwhile to evaluate whether this model is also applicable to patients undergoing allo-HSCT in cases of relapse after chimeric antigen receptor engineered T-cell therapy, although the application of allo-HSCT has been declining with the increase of novel immunotherapies.

Background: Cancer survival is associated with body mass index (BMI). However, the impact of patients' baseline characteristics on allogeneic hematopoietic stem cell transplantation (allo-HSCT) outcomes remains unclear. This study aimed to examine the baseline clinical factors associated with 5-year survival rates in patients undergoing allo-HSCT. Material and Methods: This was a retrospective exploratory observational study. Patients (n = 113, 52 women; average age: 55 years) who underwent allo-HSCT at the Division of Hematology and Stem Cell Transplantation, Shizuoka Cancer Center, between January 2008 and March 2015, were included in the present study. Results: Patients with low BMI (<18.5 kg/m2) had significantly lower 5-year survival rates than those with normal (18.5-24.9 kg/m2) and high (⩾25.0 kg/m2) BMI. The 5-year survival rate was poorer for patients with sarcopenia (41.5%) than that for those without sarcopenia prior to allo-HSCT (P = .05). The 5-year survival rate was poorer for patients with geriatric nutritional risk index (GNRI < 98) (34.5%) than that for those without GNRI prior to allo-HSCT (P < .01). Conclusions: Low BMI before allo-HCST pre-treatment was a predictor of 5-year survival rates in this study. Patients undergoing allo-HSCT may require nutritional interventions during pre-treatment to reduce the risk of sarcopenia and GNRI (<98), which affects their survival rates.
ABSTRACT
INTRODUCTION: This study aimed to validate hematopoietic stem cell transplantation (HSCT) treatment via a tailored nutritional pathway in myeloablative conditioning (MAC), determine its efficacy in terms of remission, and explore associations between clinical outcomes and nutritional indicators. METHODS: We included patients who underwent MAC for HSCT at the Shizuoka Cancer Center Stem Cell Transplantation between 2015 and 2019. We evaluated outcomes from the day before treatment initiation (transplant date: day 0) to day 42. RESULTS: Among the 40 MAC cases (participant characteristics: 20/40 males, mean age of 52 years, and mean body mass index of 21.9 kg/m2), we found that the percent loss of body weight and loss of skeletal muscle mass were correlated with the basal energy expenditure rate (BEE rate; r = 0.70, p<0.001 and r = 0.49, p<0.01, respectively). Based on the receiver operating characteristics curves, the cutoff value for the BEE rate in terms of weight loss was 1.1. Salivary amylase levels did not significantly change during the treatment course. Continuous variables, including oral caloric intake and performance status, showed statistically significant correlations with nutrition-related adverse events during treatment (r = -0.93, p<0.01 and r = 0.91, p<0.01, respectively). Skeletal muscle mass before treatment initiation was an independent predictive variable for reduced 2-year survival (p = 0.04). CONCLUSION: Our results support the validity of a safe nutritional pathway with a BEE rate of 1.1 for HSCT patients pretreated with MAC. Specifically, we found that this pathway could prevent weight loss in response to nutrition-related adverse events. Skeletal muscle mass before treatment was identified as an independent risk factor for reduced 2-year survival.

BACKGROUND: This retrospective, historically controlled investigative study examined the benefit of a nutritional support pathway that included nutritional education before the start of conditioning and emphasized oral nutrition in response to nutrition-related adverse events in patients undergoing hematopoietic stem cell transplantation (HSCT). MATERIAL AND METHODS: Participants were patients undergoing allogeneic HSCT; 46 were in the control group (i.e., did not follow our nutritional pathway) and 36 were in the group that underwent nutritional intervention (enhanced nutrition group). We compared the following parameters between groups from the day before the start of conditioning to the day after completion of parenteral nutrition (PN): percent loss of body weight (%LBW), percent loss of skeletal muscle mass (%LSMM), and estimated basal energy expenditure (EBEE) sufficiency rate. The relationship between each parameter and %LBW was also examined. We also compared nutritional indices, gastrointestinal graft versus host disease (GvHD) grade, oral energy intake, and %LBW between groups. RESULTS: There was a relationship between %LBW, %LSMM, and EBEE sufficiency rate in both groups. Compared with the control group, the enhanced nutrition group had significantly improved energy intake amount, EBEE sufficiency rate, PN duration, and oral energy intake over time. The enhanced nutrition group also had increased oral energy intake, no difference in gastrointestinal GvHD grade, and improved %LBW compared with the control group. CONCLUSIONS: Use of our nutritional support pathway in patients undergoing HSCT may be beneficial for %LBW and gastrointestinal GvHD grade, enabling early enhanced nutritional intervention after HSCT.

Hematopoietic stem cell transplantation carries nutrition-related risks. Therefore, nutritional therapy needs to be initiated before transplantation even takes place. We assessed nutritional risk among patients who underwent allogeneic stem cell transplantation. We assessed nutrient supply (calorie supply and protein supply) by chart review. Assessments were made from the pretreatment phase of transplantation to after the end of parenteral nutrition in 51 patients who underwent allogeneic stem cell transplantation at Shizuoka Cancer Center between 2007 and 2012. We compared nutrition-related adverse events and parameters between two groups: those in whom % loss of body weight was ≥7.5 and those in whom % loss of body weight was <7.5. A correlation was observed between changes in weight and skeletal muscle mass (r = 0.89; P < 0.0001). A weak correlation was observed between % loss of body weight and nutrient supply of calories (r = 0.517; P = 0.0001). There were significant differences between the % loss of body weight ≥7.5 group and the % loss of body weight <7.5 group in the following variables: % loss of body weight, nutrient supply from calories and protein; orally ingested nutrient supply from calories and protein; start day of oral intake; and acute graft-versus-host disease. Orally ingested calories were negatively correlated with nutrition-related adverse events in both groups. Early and customized nutritional intervention may be optimal for all patients who undergo allogeneic stem cell transplantation to ameliorate body weight loss associated with nutrition-related adverse events.

Adult-onset hemophagocytic lymphohistiocytosis (HLH) has features that are distinct from that of HLH in pediatric patients. The clinical records at the Japanese Red Cross Kumamoto Hospital were reviewed. We retrospectively analyzed 34 patients who fulfilled the diagnostic criteria of HLH-2004. The median age of patients was 60.0 (range 15-86). Underlying diseases were diagnosed in 17 patients. They consisted of malignant lymphoma (n=3), other neoplastic disease (n=3), viral infection (n=4), collagen vascular disease (n=3), Kikuchi's disease (n=3) and drug (n=1). Underlying diseases were not diagnosed in 17 patients despite examination. The treatments were steroids (n=18), dexamethasone + cyclosporine A (CSA) + etoposide (n=4), multidrug chemotherapy (n=2), steroids and CSA (n=3). Eleven patients died during observation. In a multivariate analysis, the significant predictor for death was age at onset (hazard ratio, 1.22; 95%CI, 1.02-1.44; P=0.027). Autopsy was performed in 4 cases, but the underlying disease remained unknown in 3 of those cases. Adult-onset HLH has high diversity and various outcomes. The mechanism of adult-onset HLH is not fully understood and further research is required.
ABSTRACT
A 28-year-old man undergoing treatment for hemophagocytic syndrome developed Paecilomyces lilacinus infection in skin ulcers on the face and in the tracheotomy stoma. While his bone marrow was suppressed by chemotherapy with dexamethasone, cyclosporin and etoposide for hemophagocytic syndrome, dental infection led to subacute necrotizing fasciitis caused by Pseudomonas aeruginosa on the right side of the face, resulting in a large area of soft tissue defects. Etoposide was discontinued, and prophylactic treatment with itraconazole was initiated. The ulcers resulting from necrotizing fasciitis were treated conservatively using trafermin and alprostadil alfadex ointment 0.003 %, and near-complete re-epithelialization occurred, except on the right lower eyelid, right buccal mucosa and perioral area. However, 6 weeks later, pustules/crusts started to form and break down repeatedly, leading to expansion of tissue defects on the face. Direct microscopic examination revealed fungal elements, and fungal culture identified Paecilomyces lilacinus suspicious twice some other day. Based on DNA extraction from the isolated fungus, this fungal strain was identified as Paecilomyces lilacinus. Cyclosporin and itraconazole were discontinued, and treatment with liposomal amphotericin B and a tapering dose of steroids was initiated. Cure was achieved in approximately 2.5 months after treatment initiation, and no relapse has been observed. The most important factor that ultimately contributed to the resolution of fungal infection might have been release of immunosuppression by discontinuing cyclosporin and tapering steroids.
