Conditions

Head and neck squamous cell carcinoma, thyroid carcinoma

Brief summary

qualitative count of lesions with significant [¹⁸F]AlF-PSMA-11 uptake on PET. For each subject, all endpoints are measured within 12 months after the last trial-specific intervention (trial-specific PET/CT or blood sampling) for that subject (LTIS). For the whole trial, all endpoints are measured within 12 months after the overall last trial-specific intervention (LTI), that is, after the last of all LTISs. (analyse PET images and blood and tissue samples until 12 months after the overall LTISs)

Detailed description

semiquantitative lesion radiotracer [¹⁸F]AlF-PSMA-11 uptake values on PET. For each subject, all endpoints are measured within 12 months after LTIS. For the whole trial, all endpoints are measured within 12 months after LTI.(analyse PET images and blood and tissue samples until 12 months after the overall LTISs), semiquantitative organ-level radiotracer [¹⁸F]AlF-PSMA-11 uptake values on PET. For each subject, all endpoints are measured within 12 months after LTIS. For the whole trial, all endpoints are measured within 12 months after LTI.(analyse PET images and blood and tissue samples until 12 months after the overall LTISs)
