Background: To evaluate the prognostic value of tumor growth patterns on magnetic resonance (MR) images in patients with locally advanced cervical cancer (LACC) treated with definitive radiotherapy or concurrent chemoradiotherapy (RT/CCRT).
Methods: We retrospectively reviewed 102 patients with LACC who received definitive RT/CCRT and who underwent MR imaging before RT/CCRT. Growth patterns on pretreatment T2-weighted MR images were classified into expansive or infiltrative type according to tumor morphologic patterns in the myometrium and/or parametrial space.
Background: A proper balance between the activator and the repressor form of GLI3, a zinc-finger transcription factor downstream of hedgehog signaling, is essential for proper development of various organs during development. Mutations in different domains of the GLI3 gene underlie several congenital diseases including Greig cephalopolysyndactyly syndrome (GCPS) and Pallister-Hall syndrome (PHS).
Case Presentation: Here, we describe the case of an overlapped phenotype of these syndromes with agenesis of the gallbladder and the pancreas, bearing a c.
Article Synopsis
- Primary extranodal malignant lymphoma of the thyroid is rare and typically involves neoplastic transformation of B cells, particularly germinal center-like or memory B cells.
- An autopsy of an 83-year-old Japanese woman revealed a non-GCB subtype of diffuse large B-cell lymphoma (DLBCL) that lacked common mutations usually found in more aggressive forms.
- This case highlights a unique subtype of DLBCL, categorized as type 3, which exhibits extremely aggressive local behavior without typical genetic markers associated with activated B-cell types.
