Retrospective Evaluation of Survival and Prognostic Factors in Immune Thrombocytopenia: A Single-Center and Cross-Sectional Study.

Immune thrombocytopenia (ITP) is an autoimmune disease characterized by the autoantibody-mediated destruction of platelets. The treatment of ITP aims to maintain a sufficient platelet count to prevent bleeding. First-line treatment options include corticosteroids and intravenous immunoglobulin (IVIg), while second-line treatments include splenectomy, rituximab and other immunosuppressive agents, and thrombopoietin (TPO) receptor agonists.

The prognostic significance of CD117-positive mast cells and microvessel density in colorectal cancer.

The prognostic significance of angiogenesis has been demonstrated in various types of cancer. However, in colorectal cancer (CRC), there are conflicting results regarding the relationship between angiogenesis and clinical-histopathological prognostic factors. Mast cells are immune system cells found in the inflammatory microenvironment; their role in carcinogenesis and prognosis remains unclear although they are considered to cause cancer development and progression.

The Impact of Hematologic Parameters on Histopathologic Features of Colorectal Cancer.
