Active clinical trials for "Tonsillar Neoplasms"

The objective of this trial is to study the efficacy of treatment of human papilloma virus (HPV) related oropharyngeal cancer with chemotherapy followed by Transoral Robotic Surgery (TORS) as definitive treatment. Current treatment of oropharyngeal cancer are chemo-radiotherapy. There is significant lifelong side effects associated with this approach related to tissue effects of radiotherapy. The side effects results in significant quality of life deterioration among the patients. Overall there is 20% failure rate with this treatment approach. The study hypothesis is that treatment with upfront (neoadjuvant) chemotherapy followed by transoral surgery and neck dissection is highly effective treatment allowing competitive cure rate compared to chemo-radiotherapy with less than 10% failure rate, while avoiding radiotherapy in majority of cases. It is also hypothesized that better functional and quality of life outcome maybe achieved with this approach.

In this trial, patients with early squamous cell carcinoma of the tonsil with clinical stage T1-2 (p16-positive or p16-negative) N0-1 (p16-positive)/N0-N2b (p16-negative) according to American Joint Committee on Cancer (AJCC) 8th edition, aimed for unimodal and ipsilateral treatment with radiotherapy with curative intent will be included. The patients will be randomized to in a 1:1 ratio to receive radiotherapy with either photons (conventional radiotherapy) versus radiotherapy with protons.

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.

The goal of this observational longitudinal study is to learn about circulating tumor Human Papilloma Virus-DNA (ctHPV-DNA) as a biomarker for HPV positive oropharyngeal cancer and cancer of unknown primary of the head and neck. The main questions it aims to answer are: Can ctHPV-DNA be used for treatment evaluation in HPV positive oropharyngeal cancer and cancer of unknown primary of the head and neck? Can circulating HPV-DNA be used as a biomarker for recurrent disease during surveillance? Participants will be asked to leave plasma samples at diagnose, at the end of treatment and at every clinical follow-up. The patients are there own controls.

Open-label, Phase I-II, first-in-human (FIH) study for A166 monotherapy in HER2-expressing or amplified patients who progressed on or did not respond to available standard therapies. Patients must have documented HER2 expression or amplification. The patient must have exhausted available standard therapies. Patients will receive study drug as a single IV infusion. Cycles will continue until disease progression or unacceptable toxicity.

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.

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.
