[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

Background: 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. Objective: To test a study drug (\[212Pb\]VMT-Alpha-NET) in people with tumors that have SSTRs. Eligibility: People aged 18 years and older with tumors of the lung, kidneys, head and neck, digestive tract, or adrenal glands that have SSTRs. Their tumors must have spread to other organs and cannot be removed with surgery. Design: Participants will be screened. They will have a physical exam with blood and urine tests. They will have imaging scans and a test of their heart function. A sample of tumor tissue may be collected if one is not already available. \[212Pb\]VMT-Alpha-NET is given through a tube attached to a needle inserted into a vein. The drug will be given on the first day of four 8-week cycles. Participants will stay in the hospital for a few nights after each dose. They will have blood tests once a week during each cycle. Some participants will also get imaging with a related study drug (\[203Pb\]VMT-Alpha-NET). They will receive this drug within 30 days before each cycle. At 1, 4, 24, and 48 hours after each \[203Pb\]VMT-Alpha-NET infusion and 4 hours after each \[212Pb\]VMT-Alpha-NET infusion, they will have optional whole body scans. These scans will show where the study drug went in their body. Following treatment, participants will be invited to the NIH Clinical Center 8 weeks after the last study drug administration for an end of treatment (EOT) visit. After EOT, visits will continue every 12 weeks for years 1-3 and every 6 months for years 4-6 or until disease progression. Beyond 6 years (or disease progression), participants will be contacted yearly to assess health status for 10 years after EOT.

A Study of SI-B036 in Patients With Locally Advanced or Metastatic Head and Neck Tumors and Other Solid Tumors

This is an open-label, multicenter, non-randomized Phase I clinical study to evaluate the safety, tolerability, pharmacokinetic characteristics and preliminary efficacy of SI-B036 Bispecific Antibody Injection in patients with locally advanced or metastatic head and neck tumors and other solid tumors.

Comparison of NeuroEXPLORER PET/CT Versus Standard-of-care PET/CT of the Head and Neck Region.

The goal of this clinical study is to compare the current standard-of-care PET/CT scanner with the new NeuroEXPLORER PET/CT, with the aim of demonstrating the added diagnostic value of the new scanner. As this is the first device of its kind in Europe, the study will also evaluate the safety and general feasibility of the NeuroEXPLORER system for head and neck PET studies. Due to to its high resolution, the NeuroEXPLORER enables an accurate investigation of areas up to 20 times smaller than what can be visualized with standard clinical PET scanners, providing images with a very high level of detail. This scanner is specifically designed for imaging the brain, spinal cord, and neck region, to support the diagnosis and monitoring of neurological, psychiatric, and other disorders in the head and neck. The main questions this study aims to answer are: * Does the NeuroEXPLORER provide more detailed information with better diagnostic quality compared to standard clinical PET/CT scans for head and neck disorders? * Is the NeuroEXPLORER system safe and effective in performing head and neck studies? Participants will: * receive clear information about the study, including its organization, possible risks, and potential benefits. Based on this, they will be able to give their informed consent by signing an informed consent form before the study begins. * visit the clinic (UZ Leuven) once for two consecutive PET/CT scans: first the prescribed clinical scan, followed by a shorter scan with the NeuroEXPLORER. * before the start of the regular PET/CT scan, have a small catheter placed in a blood vessel in the forearm. Through this, a tracer will be administered. A tracer is a small amount of slightly radioactive material that helps to produce images of processes inside the body. Depending on the tracer used, the PET/CT scan may start immediately or after a short waiting period. * lie on their back on the scanner bed for 10 to 30 minutes during the clinical scan. * after the clinical scan, undergo a 15-20 minute scan on the NeuroEXPLORER. * leave the hospital after completing both scans. * afterwards, be asked whether they experienced any discomfort during the study. In addition, they will receive a one-time follow-up phone call within a week after the scan to check if they experienced any discomfort in the days following the study.

Sub-topic Four: Clinical Translation of Original Radioactive Drugs for Precision Diagnosis and Treatment of Gastrointestinal Tumors -Clinical Application Value of PET Imaging Targeting LRRC15 in Malignant Tumors

This project utilizes LRRC15-specific targeted PET radiotracers to perform PET/MR or PET/CT imaging on healthy volunteers and patients with clinically suspected or confirmed malignancies characterized by high LRRC15 expression-including pancreatic cancer, breast cancer, lung cancer, sarcoma, head and neck tumors, glioblastoma, colorectal cancer, and melanoma. The study aims to achieve the following objectives: For patients with malignant tumors: To diagnose and stage the disease. By comparing the imaging results against the gold standard of histopathological diagnosis, the study aims to evaluate diagnostic efficacy, ascertain the presence or absence of lesions, and characterize their anatomical location and nature. Furthermore, through comparison with \[¹⁸F\]FDG PET or \[⁶⁸Ga\]Ga-FAPI PET, the study seeks to achieve accurate disease staging, assess tumor burden, and facilitate therapeutic decision-making. For healthy volunteers: To conduct pharmacokinetic analyses to determine the in vivo biodistribution and metabolic patterns of the radiotracer, as well as to evaluate its safety profile.

Multiparametric Imaging-based Intraoperative Navigation for Guidance of Surgical Resection and Postoperative Radiotherapy in Patients With Head-and-neck Tumors

The overarching goal of the NAVIGATORR trial is the improvement of local tumor control in head-and-neck cancer (HNC) by increasing the precision of surgical resection and individualization of radiotherapy. Squamous cell carcinomas (SCC) together with salivary gland carcinomas (adenoid cysytic Carcinoma (ACC), mucoepidermoid Carcinoma (MEC), adenocarcinoma (AC)) represent the most common entities in German head and neck oncology. In localized tumors, primary tumor resection with possible adjuvant (chemo)radiotherapy is still the treatment of choice. Advances in targeted therapy and immunotherapy have greatly expanded the repertoire of medical oncology in recent years. In particular, prognosis of patients with end-stage non-small cell lung cancer (NSCLC) has been improved and even patients with advanced head and neck disease can be offered new second line regimes. Importantly, all of these advances are based on personalized and targeted therapies. Unfortunately, surgical oncology in the head-and-neck region has not yet shown such developments towards individualized treatment, so that the rates of safe oncological resections (clear resection margins) haven been stagnating. Despite advances in reconstructive surgery that allow the resection of head-and-neck tumors that would not have been operable 10 - 15 years ago, the basic principles of the resection margin and especially margin evaluation have remained unchanged. The technique of navigation-based tumor resection and the annotation of biopsies by titanium clip-markings or special annotation have been described, but only in small case series and without proving the benefit of the method concerning clinically relevant parameters. Therefore, the NAVIGATORR trial will enroll 60 patients with HNC of the midface that will undergo navigation-based surgery. Importantly, interdisciplinary data exchange of the intraoperative navigation data between surgeons, pathologists and radiation oncologists will be established. Clear surgical margins (distance between tumor cells and resection border \> 5 mm) have been defined as primary endpoint. Secondary endpoints such as dosimetric assessment of individualized radiotherapy plans, local tumor control or overall survival should then be compared to data from the literature to further assess this multidisciplinary approach.

Correlation and Predictive Research of Metal Elements in Radiation-Induced Oral Mucositis

Radiotherapy is the main treatment method for head and neck tumors. However, almost all patients with head and neck tumors will develop acute inflammatory reactions such as Radiotherapy-Induced Oral Mucositis (RIOM) after receiving Radiotherapy, resulting in a decline in the quality of life of patients, hindering the smooth implementation of the treatment plan, reducing the therapeutic effect, and increasing the economic burden of patients. However, the current treatment strategies for RIOM focus on symptomatic treatment and have little impact on the course, severity and related complications of mucositis. Therefore, exploring effective strategies, predicting the incidence and severity of RIOM in patients, and providing prevention and treatment are the clinical bottlenecks and cutting-edge issues that urgently need to be solved in the current clinical practice of radiotherapy for head and neck tumors. Previous studies have shown that the steady-state of metallic elements may be closely related to the occurrence and development of RIOM. Therefore, we plan to conduct a prospective, single-center, observational study to further explore the correlation between metal elements and severe RIOM, analyze its predictive efficacy, and observe the dynamic changes of metal elements in radiotherapy.

Study of the Contribution of Mutant p53/YAP Proteins to Therapy Resistance in Recurrent Head and Neck Cancer

Multicenter, non-interventional, retrospective/prospective study of a biological nature, on patients affected by head and neck tumors, for which the collection and use of tissue samples is planned for the study of the mutational profile, the transcriptional profile and the proteomic profile.

Breathomics in the Diagnosis and Prediction of Radiotherapy-Induced Oropharyngeal Mucositis in Head and Neck Tumors

Radiotherapy-Induced Oropharyngeal Mucositis (RIOM) is one of the most distressing side effects for patients with head and neck tumors during radiotherapy, requiring clinical physicians to manage it according to the severity of mucositis to alleviate symptoms and improve quality of life. However, traditional diagnosis of RIOM overly relies on subjective evaluation, lacks early sensitivity, and existing biomarker diagnostic methods suffer from insufficient efficacy, invasiveness, and inconsistent results. This study aims to explore the diagnostic and predictive value of exhaled breathomics in RIOM of head and neck tumors. By collecting exhaled breath samples from head and neck tumor patients undergoing radiotherapy and analyzing volatile organic compounds (VOCs) using breath detection technology, we aim to develop and validate a non-invasive diagnostic and predictive model based on exhaled breathomics. The study will identify specific VOCs as potential biomarkers, providing new tools for early diagnosis, timely prediction, and personalized treatment of RIOM.
