Myeloid/lymphoid neoplasm with fibroblast growth factor receptor 1 (FGFR1) rearrangement

Myeloid/lymphoid neoplasm with fibroblast growth factor receptor 1 (FGFR1) rearrangement, historically recognized as 8p11 myeloproliferative syndrome or stem cell leukemia/lymphoma, is an ultra-rare, aggressive hematologic malignancy originating from a multipotent hematopoietic stem cell Pathophysiologically, chromosomal translocations involving the *FGFR1* gene at chromosome band 8p11 generate constitutively active tyrosine kinase fusion oncoproteins that drive uncontrolled cellular proliferati...

Myeloid/lymphoid neoplasm with fibroblast growth factor receptor 1 (FGFR1) rearrangement, historically recognized as 8p11 myeloproliferative syndrome or stem cell leukemia/lymphoma, is an ultra-rare, aggressive hematologic malignancy originating from a multipotent hematopoietic stem cell

It primarily affects the bone marrow, peripheral blood, and lymphatic systems across a broad range of adult and pediatric populations Clinically, it frequently presents with peripheral eosinophilia, lymphadenopathy, or splenomegaly, and can manifest as a chronic myeloproliferative neoplasm, acute myeloid leukemia, T- or B-cell lymphoblastic lymphoma/leukemia, or mixed-phenotype acute leukemia, characteristically exhibiting a rapid propensity for transformation into refractory blast-phase disease

Pathophysiologically, chromosomal translocations involving the *FGFR1* gene at chromosome band 8p11 generate constitutively active tyrosine kinase fusion oncoproteins that drive uncontrolled cellular proliferation and survival

Pathophysiologically, chromosomal translocations involving the *FGFR1* gene at chromosome band 8p11 generate constitutively active tyrosine kinase fusion oncoproteins that drive uncontrolled cellular proliferation and survival Clinically, it frequently presents with peripheral eosinophilia, lymphadenopathy, or splenomegaly, and can manifest as a chronic myeloproliferative neoplasm, acute myeloid leukemia, T- or B-cell lymphoblastic lymphoma/leukemia, or mixed-phenotype acute leukemia, characteri...
