文摘Conditioning regimens employed in autologous stem cell transplantation have been proven useful in various hematological disorders and underlying malignancies;however,despite being efficacious in various instances,negative consequences have also been recorded.Multiple conditioning regimens were extracted from various literature searches from databases like PubMed,Google scholar,EMBASE,and Cochrane.Conditioning regimens for each disease were compared by using various end points such as overall survival(OS),progression free survival(PFS),and leukemia free survival(LFS).Variables were presented on graphs and analyzed to conclude a more efficacious conditioning regimen.In multiple myeloma,the most effective regimen was high dose melphalan(MEL)given at a dose of 200/mg/m2.The comparative results of acute myeloid leukemia were presented and the regimens that proved to be at an admirable position were busulfan(BU)+MEL regarding OS and BU+VP16 regarding LFS.In case of acute lymphoblastic leukemia(ALL),BU,fludarabine,and etoposide(BuFluVP)conferred good disease control not only with a paramount improvement in survival rate but also low risk of recurrence.However,for ALL,chimeric antigen receptor(CAR)T cell therapy was preferred in the context of better OS and LFS.With respect to Hodgkin’s lymphoma,mitoxantrone(MITO)/MEL overtook carmustine,VP16,cytarabine,and MEL in view of PFS and vice versa regarding OS.Non-Hodgkin’s lymphoma patients were administered MITO(60 mg/m2)and MEL(180 mg/m2)which showed promising results.Lastly,amyloidosis was considered,and the regimen that proved to be competent was MEL 200(200 mg/m2).This review article demonstrates a comparison between various conditioning regimens employed in different diseases.
文摘BACKGROUND Although chemotherapy is effective for treating advanced gastric carcinoma(aGC),it may lead to an adverse prognosis.Establishing a highly effective and low-toxicity chemotherapy regimen is necessary for improving efficacy and outcomes in aGC patients.AIM To determine the efficacy and safety of cetuximab(CET)combined with the FOLFOX4 regimen(infusional fluorouracil,folinic acid,and oxaliplatin)as firstline therapy for patients with aGC,who received evidence-based care(EBC).METHODS A total of 117 aGC patients who received EBC from March 2019 to March 2022 were enrolled.Of these,60 in the research group(RG)received CET+FOLFOX4 as first-line therapy,whereas 57 in the control group(CG)received FOLFOX4.The efficacy[clinical response rate(RR)and disease control rate(DCR)],safety(liver and kidney dysfunction,leukopenia,thrombocytopenia,rash,and diarrhea),serum tumor marker expression[STMs;carbohydrate antigen(CA)19-9,CA72-4,and carcinoembryonic antigen(CEA)],inflammatory indicators[interleukin(IL)-2 and IL-10],and quality of life(QOL)of the two groups were compared.RESULTS A markedly higher RR and DCR were observed in the RG compared with the CG,with an equivalent safety profile between the two groups.RG exhibited notably reduced CA19-9,CA72-4,CEA,and IL-2 levels following treatment,which were lower than the pre-treatment levels and those in the CG.Post-treatment IL-10 was statistically increased in RG,higher than the pre-treatment level and the CG.Moreover,a significantly improved QOL was evident in the RG.CONCLUSION The CET+FOLFOX4 regimen is highly effective as first-line treatment for aGC patients receiving EBC.It facilitates the suppression of STMs,ameliorates the serum inflammatory microenvironment,and enhances QOL,without increased adverse drug effects.

文摘BACKGROUND Patients with resectable gastric adenocarcinoma accompanied by vascular cancer thrombus(RGAVCT)have a poor prognosis,with a 5-year survival rate ranging from 18.42%-53.57%.These patients need a reasonable postoperative treatment plan to improve their prognosis.AIM To determine the most effective postoperative chemotherapy regimen for patients with RGAVCT.METHODS We retrospectively collected the clinicopathological data of 530 patients who un-derwent radical resection for gastric cancer between January 2017 and January 2022 and who were pathologically diagnosed with gastric adenocarcinoma with a choroidal cancer embolus.Fur-thermore,we identified the high-risk variables that can influence the prognosis of patients with RGAVCT by asse-ssing the clinical and pathological features of the patients who met the inclusion criteria.We also assessed the significance of survival outcomes using Mantel-Cox univariate and multivariate analyses.The subgroups of pa-tients with stages Ⅰ,Ⅱ,and Ⅲ disease who received single-,dual-,or triple-drug regimens following surgery were analyzed using SPSS 25.0 and the ggplot2 package in R 4.3.0.RESULTS In all,530 eligible individuals with RGAVCT were enrolled in this study.The median overall survival(OS)of patients with RGAVCT was 24 months,and the survival rates were 80.2%,62.5%,and 42.3%at 12,24,and 59 months,respectively.Preoperative complications,tumor size,T stage,and postoperative chemotherapy were identified as independent factors that influenced OS in patients with RGAVCT according to the Cox multivariate analysis model.A Kaplan-Meier analysis revealed that chemotherapy had no effect on OS of patients with stage Ⅰ or Ⅱ RGAVCT;however,chemotherapy did have an effect on OS of stage Ⅲ patients.Stage Ⅲ patients who were treated with chemotherapy consisting of dual-or triple-agent regimens had better survival than those treated with single-agent regimens,and no significant difference was observed in the survival of patients treated with chemo-therapy consisting of dual-or triple-agent regimens.CONCLUSION For patients with stage Ⅲ RGAVCT,a dual-agent regimen of postoperative chemotherapy should be recom-mended rather than a triple-agent treatment,as the latter is associated with increased frequency of adverse events.
文摘Objective:To systematically evaluate the clinical effects of the follicular phase long regimen and the luteal phase long regimen on ovulation induction in IVF-ET treatment.Methods:Databases including PubMed,Embase,Cochrane Library,CNKI,Chinese Biomedical Literature(CBM),VIP,Wanfang,and others were searched up to January 2021.Clinical studies on ovulation induction using the follicular phase long regimen and luteal phase long regimen in IVF-ET treatment were identified.Literature screening,data extraction,and quality evaluation were conducted based on inclusion and exclusion criteria.Meta-analysis was performed using RevMan 5.3 software.Results:After screening,a total of 11 studies were included,comprising 21,544 patients:9,974 in the follicular phase long regimen group and 11,570 in the luteal phase long regimen group.The meta-analysis results were as follows:(1)The number of Gn days and the total amount of Gn in the follicular phase long regimen were higher than those in the luteal phase long regimen(P<0.05);(2)The number of eggs obtained in the follicular phase long regimen was higher than that in the luteal phase long regimen(P<0.05).There were no significant differences in the rate of embryo optimization and cycle cancellation between the two groups(P>0.05);(3)The embryo implantation rate and clinical pregnancy rate in the follicular phase long regimen were higher than those in the luteal phase long regimen(P<0.05),while the abortion rate in the follicular phase long regimen was lower than that in the luteal phase long regimen(P<0.05).Conclusion:Compared to the luteal phase long regimen,the follicular phase long regimen involves more Gn days and a higher total amount of Gn.The optimal embryo rate and cycle cancellation rate were similar between the regimens,but the follicular phase long regimen resulted in more eggs,significantly improved the implantation and clinical pregnancy rates,and reduced the abortion rate.However,these conclusions require further validation through more multicenter,large-sample RCT studies.
