Methods:
Twelve patients with AML who were hospitalized in the Affiliated Cancer Hospital of Zhengzhou University from August 2013 to May 2019 were selected. These patients were previously treated with thalidomide combined with IFN and IL-2, and then treated with combined with IFN and IL-2. According to the Frence-American-British (FAB) classification system, there was 1 case of M0, 1 case of M1, 4 cases of M2a, 3 cases of M2b, 1 case of M4EO, and 2 cases of M5b. There were 2 cases with FLT3-ITD mutation-positive, 1 case with c-kit mutation-positive. There were 2 cases in the low-risk group, 7 cases in the intermediate-risk group, and 3 cases in the high-risk group. Three cases were refractory AML, 7 cases were relapsed AML (including 3 cases of recurrence once, 4 cases of recurrence twice; 5 cases of recent recurrence, 2 cases of long-term recurrence), 2 cases were MRD-positive. The efficacy and adverse reactions of 12 cases were evaluated.
Results:
Twelve patients had received more than one cycle therapy of lenalidomide combined with IFN and IL-2, of which 4 patients achieved morphological complete remission (CR), 2 patients had CR with incomplete recovery of blood cells (CRi), 4 patients had no remission, 1 case had a decrease in MRD, and 1 case had an increase in MRD, and the total effective (CR+ CRi+ partial remission+ MRD decreased) was in 7 cases. There were no adverse reactions such as rash, constipine, bradycardia and peripheral neuritis; six patients had grade Ⅲ or higher experienced myelosuppression. No patients died of complications during the treatment, and the duration of remission of all patients was 2-20 months.
Conclusion
Lenalidomide combined with IFN and IL-2 for treatment of refractory/relapsed or MRD-positive AML is effective, and it can reduce the MRD value in MRD-positive patients, it could be a new treatment method for AML.

BACKGROUND:Clinical treatment for colon cancer mainly includes fluorouracil,irinotecan and oxaliplatin-based therapy.Studies have shown that membrane transport proteins such as ATP-binding cassette transport protein of G2(ABCG2)mediate the transport of these drugs.However,when patients develop resistance to these chemotherapeutic drugs,the high expression of ABCG2 leads to a significant decrease in the therapeutic effect and raises the problem of drug resistance in colon cancer.New drugs and treatments are urgently needed to improve the efficacy.Lycium barbarum polysaccharide has a wide range of biological activities.It can be used as anti-tumor drug to overcome the damage to normal cells in the process of chemotherapy and radiotherapy in tumor patients. OBJECTIVE:To explore the reversal effect of Lycium barbarum polysaccharide in combination with oxaliplatin on colon cancer drug-resistant cells through in vitro experiments to investigate the possible molecular mechanism of Lycium barbarum polysaccharide reversal on colon cancer drug-resistant cells. METHODS:Colon cancer cell line HCT116 and oxaliplatin-resistant cell line HCT116-OXR were selected for in vitro experiments.The optimal intervention concentration and intervention time of Lycium barbarum polysaccharide and oxaliplatin were determined by CCK8 assay of cell proliferation.Samples were further divided into the HCT116 control group,HCT116-OXR blank treatment group,Lycium barbarum polysaccharide group(2.5 mg/mL Lycium barbarum polysaccharide),and oxaliplatin group(10 μmol/L oxaliplatin),and Lycium barbarum polysaccharide + oxaliplatin group(2.5 mg/mL Lycium barbarum polysaccharide +10 μmol/L oxaliplatin).Cell apoptosis was detected by flow cytometry.The protein expression levels of phosphomannose isomerase(PMI)and ABCG2 were detected by immunofluorescence and western blot assay.Phosphatidylinositol3-kinase(PI3K),protein kinase B(AKT),B-cell lymphoma 2(Bcl-2)and BCL2-Associated X(Bax)were detected by western blot assay. RESULTS AND CONCLUSION:(1)HCT116-OXR was more sensitive to Lycium barbarum polysaccharide compared to HCT116(P<0.05).(2)Compared with the HCT116-OXR blank group,Lycium barbarum polysaccharide + oxaliplatin could promote apoptosis of HCT116-OXR cells(P<0.05).The protein expression of Bcl-2 was significantly down-regulated(P<0.05);the protein expression of Bax was significantly up-regulated(P<0.05);the protein expression of ABCG2,PMI,PI3K and AKT was significantly down-regulated(P<0.05).(3)These results indicate that Lycium barbarum polysaccharide reverses drug resistance in colon cancer by inhibiting PMI/PI3K/AKT signaling pathway,which lays the foundation for studying the molecular mechanism of Lycium barbarum polysaccharide's sensitizing chemotherapeutic effects.
