Metabolic flux analysis of 3D spheroids reveals significant differences in glucose metabolism from matched 2D cultures of colorectal cancer and pancreatic ductal adenocarcinoma cell lines
Tidwell, Tia R.; Røsland, Gro Vatne; Tronstad, Karl Johan; Søreide, Kjetil; Hagland, Hanne Røland (Peer reviewed; Journal article, 2022-05)Background Most in vitro cancer cell experiments have been performed using 2D models. However, 3D spheroid cultures are increasingly favored for being more representative of in vivo tumor conditions. To overcome the ... -
Metformin treatment response is dependent on glucose growth conditions and metabolic phenotype in colorectal cancer cells
Alhourani, Abdelnour H.; Tidwell, Tia R.; Bokil, Ansooya Avinash; Røsland, Gro V.; Tronstad, Karl Johan; Søreide, Kjetil; Hagland, Hanne R. (Peer reviewed; Journal article, 2021-05)Cancer cells exhibit altered metabolism, a phenomenon described a century ago by Otto Warburg. However, metabolic drug targeting is considered an underutilized and poorly understood area of cancer therapy. Metformin, a ... -
Molecular subtypes in stage II-III colon cancer defined by genomic instability: Early recurrence-risk associated with a high copy-number variation and loss of RUNX3 and CDKN2A
Berg, Marianne; Nordgård, Oddmund; Kørner, Hartwig; Oltedal, Satu; Smaaland, Rune; Søreide, Jon Arne; Søreide, Kjetil (Journal article; Peer reviewed, 2015)Abstract Objective We sought to investigate various molecular subtypes defined by genomic instability that may be related to early death and recurrence in colon cancer. Methods We sought to investigate various ... -
A multilevel, step-based model to evaluate progress in procedure efficiency for laparoscopic appendicectomy in surgical training: structured evaluation using 'ebb-and-flow' and 'string-of-pearls' concepts
Søreide, Kjetil; Skjold-Ødegaard, Benedicte (Peer reviewed; Journal article, 2022)Background Surgical training is aimed towards entrusted professional activity to obtain operative independence. Laparoscopic appendicectomy is performed early in training but except for simulators, real-life evaluation ... -
The overriding role of surgery and tumor grade for long-term survival in patients with gastroenteropancreatic neuroendocrine neoplasms: A population-based cohort study
Søreide, Jon Arne; Kvaløy, Jan Terje; Lea, Dordi; Sandvik, Oddvar M.; Al-Saiddi, Mohammed; Haslerud, Torjan M.; Garresori, Herish; Karlsen, Lars Normann; Gudlaugsson, Einar; Søreide, Kjetil (Peer reviewed; Journal article, 2021-06)Background Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) comprise a heterogeneous disease group. Factors that affect long-term survival remain uncertain. Complete population-representative cohorts with long-term ... -
Prevalence of PD‑L1 expression is associated with EMAST, density of peritumoral T‑cells and recurrence‑free survival in operable non‑metastatic colorectal cancer
Watson, Martin Matthew Christian; Lea, Dordi; Gudlaugsson, Einar; Skaland, Ivar; Hagland, Hanne Røland; Søreide, Kjetil (Peer reviewed; Journal article, 2020-08)Introduction Microsatellite instability (MSI) predict response to anti-PD1 immunotherapy in colorectal cancer (CRC). CRCs with MSI have higher infiltration of immune cells related to a better survival. Elevated Microsatellite ... -
Priorities for research in trauma care: creating a bucket list
Søreide, Kjetil; Weber, Clemens; Thorsen, Kenneth (Peer reviewed; Journal article, 2020)Trauma represents a major global health burden, yet receives disproportionally less funding compared to other medical conditions. One report found that injury research constituted only 6% of all research grants provided ... -
Refined TNM-staging for pancreatic adenocarcinoma – Real progress or much ado about nothing?
Roalsø, Marcus Thomas Thor; Aunan, Jan Rune; Søreide, Kjetil (Peer reviewed; Journal article, 2020-08)In order to provide optimal cancer care and prognostication, it is necessary to stage the disease. The 8th edition of the TNM-staging for exocrine pancreatic ductal adenocarcinoma (PDAC) system has refined size-based ... -
A template to quantify the location and density of CD3 + and CD8 + tumor-infiltrating lymphocytes in colon cancer by digital pathology on whole slides for an objective, standardized immune score assessment
Lea, Dordi; Watson, Martin Matthew Christian; Skaland, Ivar; Hagland, Hanne Røland; Lillesand, Melinda; Gudlaugsson, Einar; Søreide, Kjetil (Peer reviewed; Journal article, 2021)Background In colon cancer, the location and density of tumor-infiltrating lymphocytes (TILs) can classify patients into low and high-risk groups for prognostication. While a commercially available ‘Immunoscore®’ exists, ...
