Inclusion criteria

Inclusion criteria: Study Population: Patients newly diagnosed with higher-risk MDS according to the IPSS-R scoring system, with bone marrow blasts >5%, and peripheral blood RARA expression higher than the 25th percentile of RARA expression in higher-risk MDS-negative patients. Participants must meet all of the following criteria to be enrolled: 1. Age >= 18 years; expected survival >= 3 months; 2. Within 30 days prior to enrollment, confirmed as newly diagnosed higher-risk MDS with bone marrow blasts >5% according to IPSS-R scoring system, after blood cell counts, bone marrow examination, and cytogenetic testing; 3. ECOG performance status 0-2; 4. Female participants of childbearing potential agree to use physician-approved contraception during treatment with decitabine and all-trans retinoic acid, within 1 month after the last dose of decitabine, and within 1 year after the last dose of retinoic acid; male participants with female partners who may become pregnant must agree to use physician-approved contraception throughout the study and avoid causing pregnancy in their partners during the study and for 2 months after the last dose of decitabine; 5. Adequate hepatic and renal function (creatinine <= 1.5*ULN, BUN <= 1.5*ULN, ALT <= 2*ULN, AST <= 2*ULN, total bilirubin <= 1.5*ULN); 6. Voluntarily sign the informed consent form.

Exclusion criteria

Exclusion criteria: 1. Patients who have undergone hematopoietic stem cell transplantation in the past year, or those who have a recent plan to undergo hematopoietic stem cell transplantation; 2. Patients who have previously undergone transplantation or cytotoxic therapy for the treatment of MDS, including azacitidine, decitabine, and chemotherapy; 3. Patients who have received other therapeutic drugs (besides basic treatment) within 30 days prior to Day 1 of Cycle 1, including Compound Huangdai tablets, valproate sodium, anti-thymocyte globulin, arsenic trioxide, and retinoic acid therapy; 4. Participants who have participated in other clinical trials within 30 days; 5. Patients with a history of tumors and who have received any treatment for this tumor in the past 3 years, except for superficial bladder cancer, basal cell or squamous cell carcinoma of the skin, cervical intraepithelial neoplasia (CIN), "in situ" breast cancer, or prostatic intraepithelial neoplasia (PIN); or other localized malignant tumors that have a high probability of cure after surgical excision or radiotherapy; 6. Patients with uncorrected folate deficiency or vitamin B12 deficiency; 7. Patients with active viral or bacterial infections that cannot be controlled with appropriate anti-infective therapy; 8. Patients with known positive serological response for HIV; 9. Patients with mental disorders or other conditions that prevent cooperation with the study treatments and monitoring requirements; 10. Patients with uncontrolled heart disease; 11. Bone marrow aspiration; 12. Bone marrow fibrosis Grade 2-3; 13. Patients known to be allergic to decitabine, retinoic acid, or other investigational drugs; 14. Other conditions that the investigator believes make the patient unsuitable to participate in this clinical trial.
