Filter by:The aim of the study was to examine the detection rate and tumor size evaluation in patients with suspected oropharynx cancer using a new technique with transoral ultrasound of the oropharynx. The new technique was compared to Magnetic Resonance Imaging (MRI). The study investigators included patients referred to a tertiary head & neck cancer center in Copenhagen, Denmark, with suspicion of oropharynx cancer. Patients supplied written informed consent and were included and ultrasound scanned with local anesthesia in the outpatient clinic. Blinded assessment of MRI's was performed for tumor detection and compared to ultrasound with the reference standard being histopathology biopsy results.
The purpose of the study is to compare the sensitivity and specificity of transoral ultrasound, transcervical ultrasound, Magnetic Resonance Imaging (MRI) and Positron Emission Tomography-Computerized Tomography (PET-CT) in terms of detecting primary oropharynx tumors.
Background: The incidence of human papilloma virus-driven oropharyngeal cancer (HPV-OPC), a type of head and neck cancer, is rapidly increasing within the US. Currently, there are no screening methods for early detection. HPV16 E6 antibodies combined with ultrasound imaging may be a promising method for early detection of HPV-OPC. However, prior to testing HPV16 E6 antibodies and ultrasound for HPV-OPC screening, larger studies are needed to further validate the utility of these methods in the diagnostic setting among patients with suspected and/or symptomatic HPV-OPC. Objective/Hypothesis: To investigate two promising screening modalities for the detection of HPV-OPC, transcervical ultrasound and HPV16 E6 antibodies. The investigators hypothesize that both ultrasound and HPV16 E6 antibodies will be highly sensitive for the detection of symptomatic HPV-OPC. Specific Aims: (1) Determine the sensitivity of ultrasound to characterize OPC tumors compared to current standard imaging modalities among patients with suspected or confirmed OPC. (2) To determine the sensitivity and specificity of HPV16 E6 antibodies for HPV-OPC. (3) Determine the sensitivity of ultrasound to detect HPV-OPC compared to current standard imaging modalities among patients that present with a neck mass and unknown primary tumor.
