Autor: Anders B. Olin, Adam E. Hansen, Jacob H. Rasmussen, Björn Jakoby, Anne K. Berthelsen, Claes N. Ladefoged, Andreas Kjær, Barbara M. Fischer, Flemming L. Andersen

Publikováno v: EJNMMI Physics, Vol 9, Iss 1, Pp 1-13 (2022)

Abstract Background Quantitative whole-body PET/MRI relies on accurate patient-specific MRI-based attenuation correction (AC) of PET, which is a non-trivial challenge, especially for the anatomically complex head and neck region. We used a deep learn

Background and purpose: In cancer treatment precise definition of the tumor volume is essential, but despite development in imaging modalities, this remains a challenge. Here, pathological tumor volumes from the surgical specimens were obtained and c

Outcome in patients with isolated regional recurrence after primary radiotherapy for head and neck cancer

Autor: Ivan R. Vogelius, Nina Claire Woller, Giedrius Lelkaitis, Lena Specht, Jacob H. Rasmussen, Jeppe Friborg, Anne Marie Lindegaard, Martin Zamani, Christian von Buchwald

Publikováno v: Head & Neck. 42:3161-3170

Background Isolated regional recurrences following head-neck squamous-cell carcinomas (HNSCC) are often accessible for curatively intended salvage treatment. Factors prognostic for outcome were investigated in a large cohort of HNSCC patients. Method

Intratumor heterogeneity may contribute to the ambiguous clinical results on PD-L1 status as a predictor for immunotherapy response in patients with HNSCC. This decreases the utility of PD-L1 expression from single tumour biopsies as a predictive bio
