A Pilot Study of 18F-FDG PET-CT Kinetic Analysis in Head and Neck Squamous Cell Carcinoma (HNSCC)

The purpose of this study is to see how useful the information provided from Positron Emission Tomography (PET) scans can be in the actual planning and delivery of radiation treatment to patients who have head and neck cancers. Patients participating in this study, will have (in addition to their routine tests) a PET scan before and during their radiation treatment. Following the intervention, patients will be followed as per standard practice.

Comparison Between 18F-FDG PET/CT and 18F-FDG PET/MRI in Detecting Locoregional Recurrence 3 Months After Chemoradiation Therapy (CRT) in Head and Neck Squamous Cell Carcinoma (SCC)

Comparing FDG PET/CT and FDG PET/MRI in the diagnostic accuracy of detecting local recurrence 12 weeks after the end of CRT in head and neck squamous cell carcinoma patients. Forty patients aged more than 18 years who have a histologically confirmed HNSCC and have received chemoradiation therapy will be recruited for the study. The patients will be scanned with both PET/CT and PET/MRI 12 weeks after the end of CRT.

A Multicenter Phase II Study of 18F-FDG PET/CT Guided Reduced-dose Radiotherapy for Nasopharyngeal Carcinoma

The purpose of this study is to explore whether 18F-FDG PET/CT guided reduced-dose radiotherapy would maintain survival outcomes in nasopharyngeal carcinoma (NPC) patients.

An Open Label Phase I PET Imaging Study to Investigate the Bio-distribution and Tumor Uptake of [89Zr]Zr-BI 765063 and [89Zr]Zr-BI 770371 in Patients With Head and Neck Squamous Cell Carcinoma, Non-small Cell Lung Cancer or Melanoma Who Are Treated With Ezabenlimab

The purpose of this study is to find out how 2 medicines called BI 765063 and BI 770371 are taken up in the tumours and how they get distributed in the body. In addition to BI 765063 or BI 770371, participants also receive ezabenlimab. BI 765063, BI 770371 and ezabenlimab are antibodies that may help the immune system fight cancer. Such therapies are also called immune checkpoint inhibitors. Participants get either BI 765063 or BI 770371 in combination with ezabenlimab as an infusion into a vein every 3 weeks. In the first weeks, doctors check how BI 765063 and BI 770371 are taken up in tumours. To do so, the doctors use imaging methods (PET/CT scans). For this, participants get BI 765063 or BI 770371 injected in a labelled form up to 2 times.

Evaluating 111In Panitumumab for Nodal Staging in Head and Neck Cancer

This phase I trial tests the safety and effectiveness of indium In 111 panitumumab (111In-panitumumab) for identifying the first lymph nodes to which cancer has spread from the primary tumor (sentinel lymph nodes) in patients with head and neck squamous cell carcinoma (HNSCC) undergoing surgery. The most important factor for survival for many cancer types is the presence of cancer that has spread to the lymph nodes (metastasis). Lymph node metastases in patients with head and neck cancer reduce the 5-year survival by half. Sometimes, the disease is too small to be found on clinical and imaging exams before surgery. 111In-panitumumab is in a class of medications called radioimmunoconjugates. It is composed of a radioactive substance (indium In 111) linked to a monoclonal antibody (panitumumab). Panitumumab binds to EGFR receptors, a receptor that is over-expressed on the surface of many tumor cells and plays a role in tumor cell growth. Once 111In-panitumumab binds to tumor cells, it is able to be seen using an imaging technique called single photon emission computed tomography/computed tomography (SPECT/CT). SPECT/CT can be used to make detailed pictures of the inside of the body and to visualize areas where the radioactive drug has been taken up by the cells. Using 111In-panitumumab with SPECT/CT imaging may improve identification of sentinel lymph nodes in patients with head and neck squamous cell cancer undergoing surgery.

Study Evaluating 111In-Panitumumab for Nodal Staging in Head and Neck Cancer

The primary purpose of the study is to assess the safety of 111In-panitumumab as a molecular imaging agent in patients with Head and Neck Squamous Cell Carcinoma. The secondary objective is to compare sensitivity and specificity of identifying sentinel lymph nodes by systemic injection of 111In-panitumumab prior to Day of Surgery versus conventional local injection with an optical dye at the time of surgery.

PET/MR of the Carotid Arteries With 68Ga DOTATATE in Patients Following Head and Neck Radiation Therapy and at Risk of Cerebrovascular Events

In this study, DOTATATE-PET/MR will be performed in up to 60 patients with a history of radiation therapy for head and neck squamous cell carcinoma over 2 years.

Radiogenomics in Aerodigestive Tract Cancers

Aerodigestive tract cancers are common malignancies. These cancers were ranked to be top-ten cancer-related deaths in Taiwan. Although many new target therapies and immunotherapies have emerged, many of the treatment eventually fail. For example, a 30-40% failure rate has been reported for target therapy, and, even higher for immune checkpoint inhibitors. A reliable model to more accurately predict treatment response and survival is warranted. The radiomic features extracted from F-18 fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) can be used to figure tumor biology such as metabolome and heterogeneity. It can therefore be used to predict treatment response and individual survival. On the other hand, genomic data derived from next-generation sequencing (NGS) can interrogate the genetic alteration of cancer cells. It can be used to feature genetic identification of the tumor and can also be used to identify target genes. However, both modalities have their weakness; a combination of the two may devise a more powerful predictive model for more precise clinical decision. The investigators plan to recruit patients aged at least 20-year with the diagnosis of aerodigestive tract cancers for radiogenomic study. Our previous studies have found that radiomic features derived from 18F-FDG PET can predict treatment response and survival in patients with esophageal cancer treated with tri-modality method. The investigators also discovered that radiomics could predict survival in patients with EGFR-mutated lung adenocarcinoma treated with target therapy. In addition, our study results showed that the level of PD-L1 expression is associated with radiomics as well. The investigators plan to add genomic data into radiomics and interrogate cancers from different aspects. The investigators seek to devise a more precise model to predict the treatment response and survival in patients with aerodigestive tract cancers.

Characterizing Dynamics of FDG Uptake With Total-Body PET for Response Assessment in Radiotherapy for Head and Neck Cancer

The overall goal of this research study is to understand how 18F-fluorodeoxyglucose (FDG), a radioactive sugar behaves in head and neck cancer (HNC) and inflammation immediately following injection and at many hours post-injection, with the world's first total-body positron emission tomography (PET)/computed tomography (CT) scanner (EXPLORER).

Phase I Trial of [212Pb]VMT-Alpha-NET in Metastatic or Inoperable Somatostatin-Receptor Positive Gastrointestinal Neuroendocrine Tumors, Pheochromocytoma/Paragangliomas, Small Cell Lung, Renal Cell, and Head and Neck Cancers

Some cancers have high levels of proteins called somatostatin receptors (SSTRs) on the surface of the tumors. These tumors can be in the lung, head and neck, digestive tract, kidneys, and in or near the adrenal glands. Researchers want to know if drug treatments that target SSTRs can help shrink these types of tumors.
