Economics and Outcome After Hematopoietic Stem Cell Transplantation: A Retrospective Cohort Study.

ABSTRACT: Hematopoietic stem cell transplantation (HSCT) is a lifesaving expensive medical procedure. Hence, more transplants are performed in more affluent countries. The impact of economic factors on patient outcome is less defined. We analyzed retrospectively a defined cohort of 102,549 patients treated with an allogeneic (N = 37,542; 37%) or autologous (N = 65,007; 63%) HSCT. They were transplanted by one of 404 HSCT centers in 25 European countries between 1999 and 2006. We searched for associations between center-specific microeconomic or country-specific macroeconomic factors and outcome. Center patient-volume and center program-duration were significantly and systematically associated with improved survival after allogeneic HSCT (HR 0·87; 0·84-0·91 per 10 patients; p < 0·0001; HR 0·90;0·85-0·90 per 10 years; p < 0·001) and autologous HSCT (HR 0·91;0·87-0·96 per 10 patients; p < 0·001; HR 0·93;0·87-0·99 per 10 years; p = 0·02). The product of Health Care Expenditures by Gross National Income/capita was significantly associated in multivariate analysis with all endpoints (R(2) = 18%; for relapse free survival) after allogeneic HSCT. Data indicate that country- and center-specific economic factors are associated with distinct, significant, systematic, and clinically relevant effects on survival after HSCT. They impact on center expertise in long-term disease and complication management. It is likely that these findings apply to other forms of complex treatments.

Project description:BackgroundHematopoietic stem cell transplantation (HSCT) is a standard therapy strategy for most malignant disorders in children. However, transplant-related pneumonia remains a major therapy challenge and mesenchymal stromal cells (MSCs) are rarely reported in HSCT-related pneumonia. The aim of our study was to assess the efficacy of MSC for HSCT-related pneumonia in children.MethodsWe retrospectively retrieved HSCT-related (severe and non-severe) pneumonia cases (aged < 18 years), which underwent MSC treatment (MSC group) or non-MSC treatment (non-MSC group) in Guangzhou Women and Children's Medical Center, from December 2017 to December 2019. We investigated outcomes of the two different treatments among severe cases and non-severe cases, respectively. The primary endpoints were differences in overall cure rate and time to cure between MSC and non-MSC groups. The secondary endpoints were 180-day overall survival and cumulative cure rate.ResultsFinally, 31 severe pneumonia cases (16 in MSC group, 15 in non-MSC group) and 76 non-severe cases (31 in MSC group, 45 in non-MSC group) were enrolled in this study. Among severe pneumonia cases, overall cure rate in MSC group was significant higher than that in non-MSC group (12[75.0%] vs. 5[33.3%]; OR = 6.00, 95% CI [1.26-28.5]; p = 0.020); the time (days) to cure in MSC group was dramatically reduced compared with that in non-MSC group (36 [19-52] vs. 62 [42-81]; OR = 0.32, 95% CI [0.12-0.88]; p = 0.009); the 180-day overall survival in MSC group was better than that in non-MSC group (74.5% [45.4-89.6] vs. 33.3% [12.2-56.4]; p = 0.013). Among non-severe pneumonia cases, the time (days) to cure in MSC group was notably decreased compared with that in non-MSC group (28 [24-31] vs. 33 [26-39]; OR = 0.31, 95% CI [0.18-0.56]; p = 0.003). Compared with non-MSC group, MSC-treated patients achieved significant improvements of cumulative cure rate not only in severe pneumonia cases (p = 0.027), but also in non-severe cases (p < 0.001).ConclusionsThis study revealed that MSC treatment could contribute to improving outcomes in children with pneumonia post-HSCT, especially in severe cases. These findings suggest MSC treatment as a promising therapy for HSCT-related pneumonia in children.

Project description:BackgroundBronchiolitis obliterans (BO) is one of the most common late non-infectious pulmonary complications after hematopoietic stem cell transplantation (HSCT). Lung transplantation (LT) is the only cure for patients with end-stage BO, but the overall efficacy is rarely reported. Our study aims to conclude and elucidate the clinical experience of our single center and provide a reference for the current selection of treatment.MethodsWe retrospectively analyzed the medical records of six patients with post-HSCT BO who received LT in our center from 2015 to 2019. The collected information included demographic data, surgery-related conditions, and postoperative follow-up data, which covered blood tests, infection status assessment, lung function assessment, anesthesia assessment, function assessment of other organs and so on. All patients were regularly followed up after discharge, which in the first year, was performed every 3 months. Over the next 2 years, patients were assessed every 6 months, and after 3 years, the frequency was once annually.ResultsThe mean age of patients at LT time was 28±13 years, with an interval of 72±48 months from HSCT. All patients developed hypercapnia with an average carbon dioxide partial pressure (pCO2) of 71.1±20.8 mmHg. Preoperative pulmonary function tests showed the mean actual forced expiratory volume in 1 second (FEV1) was 16.7%±5.9% of the predicted value in four patients. After assessment, four patients adopted sequential bilateral LT and two adopted right-sided LT. Due to hemodynamic instability, five patients adopted intraoperative assistance of extracorporeal membrane oxygenation (ECMO). One patient died of septic shock 9 days after surgery, and the other five survived healthy for 53±23 months. The actual value of FEV1 at 3 months postoperatively accounted for 57.9%±15.3% of the predicted value. No patients had recurrence of BO.ConclusionsLT may be a treatment worthy of consideration in patients with post-HSCT end-stage BO because it can improve lung function, quality of life and prolong survival of these selected patients.
