Abstract:
A 62-year-old man diagnosed with acute myeloid leukemia (AML) showed limited responses to two courses of azacitidine (AZA)+Venetoclax (VEN) therapy. Twenty days after being transferred to our hospital, flow cytometry with broad antigen coverage and mutation analysis confirmed the presence of a second malignancy, hairy cell leukemia (HCL). Following haploidentical combined umbilical cord blood transplantation, the patient achieved complete remission (CR) for both AML and HCL. This CR has been maintained for the past 14 months. Patients with dual hematologic malignancies may not respond well to conventional therapy regimens. Early initiation of hematopoietic stem cell transplantation is beneficial for improving prognosis and extending overall survival.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
