Objective To assess the clinical effectiveness and safety of inductive treatment with arsenic trioxide （As203） for acute promyelocytic leukemia （APL）. Methods Randomized controlled trials （RCTs） were identified from MEDLINE （1966 -July, 2005 ）, EMBASE （1984 -July, 2005 ）, The Cochrane Library （ Issue 3, 2005） and CBM- disc （1978 -July, 2005）. The references of eligible studies were handsearched. RCTs of As203 treating for APL were included. Data were evaluated and extracted by two reviewers independently with designed extraction form. RevMan 4. 2.7 software was used for data analysis. Results Six RCTs involving 323 patients were included. Two studies reported that there was no statistical difference between As2O3 group and all-transretinoic acid （ATRA） group in mortality for patients with APL or APL patients with complications of desseminated intiavascular coagulation or cerebra hemorrhage. The pooled result of 4 studies showed that there was no statistical difference with RR 0.98, 95 % CI 0.86 to 1.12 in complete remission （CR） rates between the two groups. The result of one study showed that the CR rate of patients with intravenous injection of As203 in 2 divided dosages with longer injection duration was higher with RR 1.31, 95% CI 0.86 to 1.12 compared with those with a single intravenous injection. Adverse effects in As2O3 group were less than ATRA group. Conclusions Inductive treatment with As2O3 for acute promyelocytic leukeuia has similar mortality and CR with less adverse effects compared with ATRA. More trials of high quality are required.
Mitochondrial quality control includes mechanisms such as mitochondria-derived vesicles, fusion / fission and autophagy. These processes rely on the collaboration of a variety of key proteins in the inner and outer membranes of mitochondria to jointly regulate the morphological structure and functional integrity of mitochondria, repair mitochondrial damage, and maintain the homeostasis of their internal environment. The imbalance of mitochondrial quality control is associated with leukemia. Therefore, by exploring the mechanisms related to mitochondrial quality control of various leukemia cells and their interactions with immune cells and immune microenvironment, this article sought possible targets in the treatment of leukemia, providing new ideas for the immunotherapy of leukemia.
Objectives To systematically review the relationship between indoor decoration and childhood leukemia in China. Methods CNKI, WanFang Data, VIP, CBM, PubMed, EMbase and The Cochrane Library databases were electronically searched to obtain case-control studies of the relationships between indoor decoration and childhood leukemia from inception to December 2016. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.3 software. Results A total of 13 studies involving 1 727 cases and 2 468 controls were included. The results of meta-analysis showed that indoor decoration could increase the risk of childhood leukemia in China (OR=2.69, 95%CI 1.82 to 3.98, P<0.000 01). Conclusions The current evidence suggests that indoor decoration is a risk factor for childhood leukemia in Chinese. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
Chronic lymphocytic leukemia (CLL) / small lymphocytic lymphoma (SLL) is a malignancy of mature B cells characterized by progressive lymphocytosis, lymphadenopathy, and splenomegaly. On February 21st 2019, with the accumulating of new data, the National Comprehensive Cancer Network updated the guideline for CLL/SLL. This article aims at providing a reasonable interpretation of the most important messages conveyed in the guideline.
ObjectiveTo report and analyze one case of Philadelphia chromosome-positive (Ph+) acute lymphoblastic leukemia (ALL) initially presented with skeletal destruction treated with imatinib-based personal therapy. MethodsWe described the therapeutic advancements for ALL cases initially presented as skeletal destruction and Ph+ ALL through case report and literature review. ResultsDefinite diagnosis of Ph+ ALL was made for the patient who subsequently obtained inductive remission and 17-month molecular remission with the aid of imatinib-based regimen. ConclusionWe should take potential diagnosis of ALL into consideration for patients with skeletal destruction. Imatinib-based standard chemotherapeutic regimen may improve therapeutic model and prognosis of Ph+ ALL.
Objective To assess the clinical effectiveness and safety of granulocyte colony stimulating factor (G-CSF) for patients with acute lymphoblastic leukemia (ALL). Methods We searched the Cochrane Library, PubMed, EMbase, CNKI, and VIP databases from January 2000 to October 2009. Randomized controlled trials (RCTs) about G-CSF for patients with ALL were retrieved. The methodological quality of the included studies was assessed and the data was extracted according the Cochrane Reviewer’s Handbook. Meta-analyses for overall survival, complete remission, quality of life, infections, relapse rate, and adverse events were performed using RevMan 5.0 software. Results Six RCTs involving 620 patients with ALL were included. The results of meta-analyses showed that the G-CFS group was superior to the control group in the overall survival of adult ALL patients (RR=2.24, 95%CI 1.28 to 3.90, P=0.004). Conclusion G-CSF can improve the overall survival of adult ALL patients. However, it is not demonstrated that G-CSF could improve complete remission rate and quality of life, and reduce infections and relapse rate. More high-quality and large scale RCTs are required.
Objective To search evidence in the treatment of Philadelphia chromosome （Ph）-positive acute lymphocytic leukemia （ALL） for guiding chnical practice. Methods We searched MEDLINE （February, 1970～July, 2005 ） and SUMSEAILCH （till July, 2005 ）to identify systematic reviews（SIL）, randomized controlled trials（RCTs） and controlled clinical trials （CCTs） in the treatment of Ph-positive ALL. Results One RCT and 8 CCTs were identified. The results showed that Ph-positive ALL had a very poor prognosis . Chemotherapy and bone marrow transplantation （BMT） were the two main ways to treat the disease. Outcome of conventional chemotherapy treatment for adults with the disease was poor. Outcome of treatment with hyper-CVAD and imatinib mesylate was better and BMT was the only way which could potentially cure the disease. Conclusions Treatment of Ph-positive ALL with hyper-CVAD and imatinib mesylate may induce higher remission rate and disease free survival rate. BMT is the best way to cure the disease.
Objective To systematically review the pharmacoeconomic evaluation related to relapsed or refractory B-cell acute lymphoblastic leukemia (r/r B-ALL), and to summarize its model structure, parameter inclusion and other methodological parts for future r/r B-ALL-related interventions, and to provide references for conducting pharmacoeconomic evaluations. Methods PubMed, EMbase, The Cochrane Library, CNKI and WanFang Data databases were electronically searched to collect relevant literature on the pharmacoeconomic evaluation model of r/r B-ALL from inception to August 6th, 2021. Two reviewers independently screened literature, extracted data, and assessed the quality of the included studies. The data on the model structure, methods, and parameter inclusion were then summarized. Results A total of 10 studies using different modeling methods were included. Due to the lack of head-to-head trials, most of the efficacy parameters for the intervention and control groups were derived from different clinical trials and compared indirectly. All studies used quality-adjusted life years (QALYs) as output indicators, and some used life years (LYs) as output indicators and reported the incremental cost effectiveness ratio (ICER). All studies measured the cost of treatment and hematopoietic stem cell transplantation; a few studies also conducted subgroup analysis. Conclusion The number of studies on the economic evaluation of r/r B-ALL is relatively small, and there are large differences in model types, health status, and parameter inclusion. It is suggested that researchers should guarantee the integrity of the report format and normative according to available data choice drug economics evaluation model and establish the reasonable hypothesis under the condition of the patient population heterogeneity uncertainty, perform subgroup analysis especially on the subgroup which did not receive salvage therapy. In the absence of head-to-head clinical trials, appropriate indirect comparison methods are adopted according to the data obtained to reduce methodological differences and improve the quality of relevant pharmacoeconomic research in China.
Objective To systematically review the health economic evaluation studies of medicines for the treatment of acute myeloid leukemia (AML). MethodsThe PubMed, EMbase, Cochrane Library, CBM, CNKI, and WanFang Data, as well as the CRD database specifically for health economics were electronically searched from inception to June 2022, and related journals in the field of health economics and the websites of HTA institutions in various countries were manually searched. The quality of the studies was assessed using the CHEERS checklist. The basic characteristics of health economics evaluation publications were summarized, the quality of model structures and methodologies was assessed and economic evaluation results were compared among different treatments. Results A total of 17 studies were included, and cost-effectiveness analyses were conducted from the perspectives of the health system, patients, the whole society, and medical insurance payers. The economic evaluation models were relatively unified, but there were differences in methods and results reporting, and the quality needed to be improved. The research objects were mainly the comparison of hypomethylating agents, targeted medicine and traditional chemotherapy regimens, as well as the comparison of different chemotherapy combinations and different drug dosages. Conclusion Real-world studies are mainly focused on traditional chemotherapy regimens, and model-based health economic evaluations, such as Markov models, are more frequently applied to newly developed targeted drugs and demethylation drugs. Among all treatments, the chemotherapy regimens including cytarabine, midostaurin, and decitabine are found to be more cost-effective.
ObjectivesTo systematically review the risk of arterial ischemic and metabolic adverse events in chronic myeloid leukemia (CML) patients treated with tyrosine kinase inhibitors (TKIs).MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were searched to collect clinical trials, observational studies and case reports of adverse events in CML patients treated with TKIs from inception to February 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 22 studies involving 4 223 patients were included. The incidence rates of ischemic heart disease in any grade were 2 per 100 patient-years (95%CI 2 to 3) for nilotinib, and 0 per 100 patient-years (95%CI 0 to 3) for imatinib. The incidence of ischemic heart disease in grade 3 or 4 was 1 per 100 patient-years (95%CI 0 to 2) for nilotinib. The incidence of peripheral arterial occlusive disease in any grade was 2 per 100 patient-years (95%CI 0 to 14) for nilotinib, and 0 per 100 patient-years (95%CI 0 to 2) for imatinib. The incidence of hypertension in any grade was 1 per 100 patient-years (95%CI 0 to 3) for nilotinib, and 44 per 100 patient-years (95%CI 27 to 71) for ponatinib. The incidence of hypertension in grade 3 or 4 was 2 per 100 patient-years (95%CI 0 to 15) for nilotinib, and 22 per 100 patient-years (95%CI 8 to 58) for ponatinib. The incidence of hyperlipidemia in any grade was 17 per 100 patient-years (95%CI 5 to 59) for nilotinib. The incidence of hyperglycemia in any grade was 11 per 100 patient-years (95%CI 9 to 15) for nilotinib, 2 per 100 patient-years (95%CI 1 to 4) for imatinib, 1 per 100 patient-years (95%CI 0 to 5) for dasatinib, and 19 per 100 patient-years (95%CI 19 to 20) for bosutinib. The incidence of hyperglycemia in grade 3 or 4 was 4 per 100 patient-years (95%CI 3 to 5) for nilotinib, and 1 per 100 patient-years (95%CI 1 to 2) for bosutinib.ConclusionsPatients treated with nilotinib have a greater possibility of ischemic heart and peripheral arterial occlusive disease compared with patients treated with imatinib. Patients treated with ponatinib have a high incidence rate of hypertension, and patients treated with nilotinib have a high incidence rate of hyperlipidemia. Patients treated with bosutinib and nilotinib have higher risk of hyperglycemia compared with patients treated with imatinib or dasatinib.
