Are 90% of deaths from cancer caused by metastases?
Dillekås, Hanna; Rogers, Michael S.; Straume, Oddbjørn (Peer reviewed; Journal article, 2019)Numerous publications have stated that metastases are responsible for 90% of cancer deaths, but data underlying this assertion has been lacking. Our objective was to determine what proportions of cancer deaths are caused ... -

Pelissier; Tiron, Crina Elena; Villadsen, René; Miyano, Masaru; Lotsberg, Maria Lie; Madeleine, Noëlly; Panahandeh, Pouda; Dhakal, Sushil; Tan, Tuan Zea; Peters, Stacey D'Mello; Grøndal, Sturla Magnus; Aziz, Sura Mohammed; Nord, Silje; Herfindal, Lars; Stampfer, Martha R.; Sørlie, Therese; Brekken, Rolf A; Straume, Oddbjørn; Halberg, Nils; Gausdal, Gro; Thiery, Jean Paul; Akslen, Lars A.; Petersen, Ole W.; LaBarge, Mark A.; Lorens, James (Journal article; Peer reviewed, 2020)The receptor tyrosine kinase AXL is associated with epithelial plasticity in several solid tumors including breast cancer and AXL-targeting agents are currently in clinical trials. We hypothesized that AXL is a driver of ... -
Baseline microvessel density predicts response to neoadjuvant bevacizumab treatment of locally advanced breast cancer
Krüger, Kristi; Silwal-Pandit, Laxmi; Wik, Elisabeth; Straume, Oddbjørn; Stefansson, Ingunn Marie; Borgen, Elin; Garred, Øystein; Naume, Bjørn; Engebråten, Olav; Akslen, Lars Andreas (Journal article; Peer reviewed, 2021)A subset of breast cancer patients benefits from preoperative bevacizumab and chemotherapy, but validated predictive biomarkers are lacking. Here, we aimed to evaluate tissue-based angiogenesis markers for potential ... -
ctDNA detected by ddPCR reveals changes in tumour load in metastatic malignant melanoma treated with bevacizumab
Forthun, Rakel Brendsdal; Hovland, Randi; Schuster, Cornelia; Puntervoll, Hanne Eknes; Brodal, Hans Petter; Namløs, Heidi Maria; Aasheim, Lars Birger; Meza, Leonardo Zepeda; Gjertsen, Bjørn Tore; Knappskog, Stian; Straume, Oddbjørn (Peer reviewed; Journal article, 2019)Bevacizumab is included in an increasing number of clinical trials. To find biomarkers to predict and monitor treatment response, cancer and angiogenesis relevant mutations in tumour and circulating tumour DNA (ctDNA) were ... -
Differences in metastatic patterns in relation to time between primary surgery and first relapse from breast cancer suggest synchronized growth of dormant micrometastases
Dillekås, Hanna Elisabet; Transeth, Monica; Pilskog, Martin; Assmus, Jørg; Straume, Oddbjørn (Peer reviewed; Journal article, 2014-08)A significant variation in the metastatic pattern among breast cancer patients exists. Clinical observations suggest that these differences are related to time to recurrence (TTR), thus suggesting a common systemic growth ... -
Distant metastasis dynamics following subsequent surgeries after primary breast cancer removal
Demicheli, Romano; Dillekås, Hanna; Straume, Oddbjørn; Biganzoli, Elia (Peer reviewed; Journal article, 2019)Background: The aim of the research was to separate the distant metastasis (DM) enhancing effect due to breast tumour removal from that due to surgical manoeuvre by itself. Methods: DM dynamics following surgery for ... -
Elevated plasma interleukin 6 predicts poor response in patients treated with sunitinib for metastatic clear cell renal cell carcinoma
Pilskog, Martin; Nilsen, Gry Hilde; Beisland, Christian; Straume, Oddbjørn (Peer reviewed; Journal article, 2019)Introduction: Clear cell renal cell carcinoma (ccRCC) is the most common type among renal cell carcinomas, and anti-angiogenic treatment is currently first line therapy in metastatic ccRCC (mccRCC). Response rates and ... -

Tzoulis, Charalampos; Schwarzlmüller, Thomas; Søfteland, Eirik; Neckelmann, Gesche; Biermann, Martin; Haroche, Julien; Straume, Oddbjørn; Gjerde, Ivar Otto; Vintermyr, Olav Karsten (Peer reviewed; Journal article, 2015-04-30)Background: Erdheim-Chester disease is a rare histiocytosis characterized by multi-systemic organ involvement. Immune-modulating agents such as interferon-alpha have limited success and the disorder is progressive and ... -
Expression of Heat Shock Protein 27 in Melanoma Metastases Is Associated with Overall Response to Bevacizumab Monotherapy: Analyses of Predictive Markers in a Clinical Phase II Study
Schuster, Cornelia; Akslen, Lars A.; Straume, Oddbjørn (Journal article, 2016-05-11)The aim of this study was to identify potential predictive biomarkers in 35 patients with metastatic melanoma treated with anti-angiogenic bevacizumab monotherapy in a clinical phase II study. The immunohistochemical ... -
HSP27 Expression as a Novel Predictive Biomarker for Bevacizumab: is it Cost Effective?
Seo, Mikyung Kelly; Straume, Oddbjørn; Akslen, Lars A.; Cairns, John Alexander (Journal article; Peer reviewed, 2020)Background: Despite the extensive use of bevacizumab in a range of oncology indications, the US FDA revoked its approval for breast cancers, and multiple negative trials in several solid malignancies have been reported, ... -
Ki-67 expression is superior to mitotic count and novel proliferation markers PHH3, MCM4 and mitosin as a prognostic factor in thick cutaneous melanoma
Ladstein, Rita Grude; Bachmann, Ingeborg M.; Straume, Oddbjørn; Akslen, Lars A. (Peer reviewed; Journal article, 2010-04-14)Background: Tumor cell proliferation is a predictor of survival in cutaneous melanoma.
