A research team led by the Medical University of Vienna has demonstrated in a recent study that the biological characteristics of a subgroup of head and neck tumours – which are very aggressive in many cases – are reflected in modern imaging techniques. PET/CT scans can thus provide clues to particularly active and prognostically unfavourable tumour types, thereby opening up new prospects for personalised treatment strategies for a type of cancer that has hitherto been difficult to treat. The results were published in the journal Molecular Cancer.
Medical imaging routinely used in cancer care may hold far more biological information than previously thought. An international study involving Umeå University guest professor Lukas Kenner shows that PET/CT scans can capture the molecular activity of particularly aggressive head and neck tumours, opening new possibilities for more precise diagnosis and treatment planning.
Immune checkpoint inhibitors are widely used in elderly cancer patients, but data on tumor-specific immune-related adverse events (irAEs) remain limited. A Chinese Medical Journal study analyzed 407 elderly patients with gastrointestinal (GI) tumors or lung cancer. Results showed higher irAE incidence in lung cancer patients, skin toxicity more prevalent in GI tumor patients, and thyroid dysfunction more common in lung cancer patients. This study provides evidence for personalized safety management of immunotherapy in elderly patients.
