A Feasibility Study of Hypoxia Imaging in Patients With Lung Cancer Using Positron Emission Tomography (PET) With 18F-Fluoroazomycin Arabinoside (18F-FAZA)

The purpose of this study is to look for low levels of oxygen (hypoxia) in lung cancer using a positron emission tomography (PET) scan. Hypoxia can influence how lung cancer grows and responds to treatments like radiotherapy and chemotherapy. The use of PET scans to measure hypoxia may be better and simpler than the approaches used previously. This study will assess whether or not PET scans can provide useful information about hypoxia in lung cancer. In this study, a radiotracer called Fluoroazomycin Arabinoside (FAZA) will be used to measure hypoxia in the patient's tumour. FAZA has already been used in many cancers including lung cancer. Patients who consent to participate in this trial will receive 1 FAZA PET Scan prior to their first radiotherapy treatment

Evaluation of 89Zr-DFO-nimotuzumab for Non-invasive Imaging of EGFR Positive Cancers by Positron Emission Tomography (PET)

Over-expression of Epidermal Growth Factor Receptor (EGFR) on cells occurs in all aggressive cancers of epithelial origin. Existing tests for monitoring EGFR expression are invasive and not reliable. There needs to be a better way to measure EGFR expression in cancerous tumors to better tailor cancer treatments. This clinical trial aims to demonstrate the feasibility of imaging cancers that express EGFR using 89Zr-DFO-nimotuzumab and Positron Emission Tomography (PET)/Computerized Tomography (CT). By non-invasively imaging the status of EGFR, 89Zr-DFO-nimotuzumab could be used to assist in the identification of patients who are likely to respond to anti-EGFR treatments, including nimotuzumab. The hypothesis is that 89Zr-DFO-nimotuzumab will accumulate to tumors over-expressing EGFR making them visible when imaged with PET/CT. This hypothesis will be tested in this study, along with the optimal imaging time and diagnostic ability.

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.

Assessments will include medical history, physical examinations, laboratory tests, and imaging. Cancer cachexia will be diagnosed based on weight loss, reduced food intake, and inflammation markers. Psychological stress will be evaluated using questionnaires and biomarkers. Metabolic changes will be assessed using positron emission tomography-computed tomography (PET-CT) scans. The primary objective is to determine differences in metabolic activity between cachectic and non-cachectic patients. Secondary objectives include evaluating changes in brain activity and exploring the relationship between stress, inflammation, and metabolism.

Prognostic Value of Combined Approach Based on KEAP1/NFE2L2 Mutations and Pre-therapeutic FDG-PET/CT Radiomic Analysis in Advanced Non-small-cell Lung Cancer PDL1 ≥ 50% Treated With Pembrolizumab.

Pembrolizumab has been approved for first-line locally advanced or metastatic NSCLC with a tumor proportion score (TPS) ≥50% for PDL1, based on the results of KEYNOTE-024. However, even with a positive PDL1 status, only a fraction of patients respond to immunotherapy. In the KEYNOTE-024 study evaluating pembrolizumab versus chemotherapy in first-line advanced NSCLC with PDL1 TPS ≥50%, the response rate in the pembrolizumab arm alone was 45%. NFE2L2 is a transcription factor that directs the expression of free radical defense genes that may interfere with radiation-induced DNA damage. KEAP1 is an adaptor protein that targets NFE2L2 for ubiquitination and proteasomal destruction as part of normal homeostasis. These new biomarkers are of clinical interest, as KEAP1/NFE2L2 mutations predict radiation resistance in patients with localized NSCLC treated with radiotherapy but not surgery. Some data also suggest a role for the KEAP1/NFE2L2 axis in response to immunotherapy. Establishing a predictive model for the presence of the KEAP1/NFE2L2 mutation would provide a tool for predicting survival (progression-free and overall), even before the patient starts immunotherapy.
