Официальное название
Towards Improved Therapy Selection and Targeted Treatment for Nasopharyngeal Carcinoma: a Proof-of-concept Pilot Study for Somatostatin Receptor 2 Imaging With [68Ga]Ga-DOTA-TOC PET/CT.
Обзор
This is an investigator-initiated, single-center clinical trial designed to evaluate the feasibility of \[68Ga\]Ga-DOTA-TOC positron emission tomography (PET) scan in patients with Epstein-Barr virus (EBV) related nasopharyngeal carcinome (NPC) prior to and three weeks after the start of induction chemotherapy or concurrent chemoradiotherapy (CRT). Archival tumor tissue from the diagnostic biopsy will be used to perform somatostatin receptor 2 (SSTR2) immunohistochemistry (IHC). Blood samples will be drawn at baseline, after three weeks, after completion of induction chemotherapy if applicable, and after CRT.

- Другое [68Ga]Ga-DOTA-TOC PET imaging
Patients will undergo \[68Ga\]Ga-DOTA-TOC PET imaging before and 3 weeks after start of standard of care treatment with induction chemotherapy or CRT, unless the baseline scan shows no tracer uptake in the tumor, in that case the scan will not be repeated. Patients will receive 120 MBq \[68Ga\]Ga-DOTA-TOC intravenously and will be scanned up to 20 minutes, 60 minutes after tracer injection, after acquisition of a low dose CT for attenuation correction. The investigators will use archival tissu
