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.

Description:

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.
