      Paulsen, Erna-Elise; Andersen, Sigve; Rakaee, Mehrdad; Pedersen, Mona Irene; Lombardi, Ana Paola; Pøhl, Mette; Kilvær, Thomas Karsten; Rasmussen Busund, Lill-Tove; Pezzella, Francesco; Dønnem, Tom (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-04-26)
      Introduction: Non-small cell lung carcinomas (NSCLC) exhibit different microvessel patterns (MVPs). Basal (BA), diffuse (DA) and papillary (PA) patterns show signs of angiogenesis (new blood vessels), while an alveolar pattern indicates that tumors are co-opting existing normal vessels (non-angiogenic alveolar, NAA). NAA tumor growth is known to exist in NSCLC, but little is known about its prognostic ...
