  5. 4. Monitoring of neuroendocrine tumor patients undergoing systemic therapies

    Författare :Olof Pettersson; Anders Sundin; Håkan Geijer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Therapy monitoring; NET; neuroendocrine tumor; computed tomography; CT; PRRT; 177Lu-DOTATATE; TGR; tumor growth rate; theranostics; DOTATOC-PET CT; Radiology; Radiologi; Endokrinologi och Diabetologi; Endocrinology and Diabetology; Oncology; Onkologi;

    Sammanfattning : Monitoring of neuroendocrine tumor (NET) patients undergoing systemic therapies is troublesome as biomarkers capable of detecting tumor responses have been difficult to establish. Changes in the sum of target lesion diameters are used to evaluate the effects of therapy according to the response evaluation criteria in solid tumors (RECIST 1.1). LÄS MER

  7. 5. Studiesituationen för elever med särskilda matematiska förmågor
