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.
