The Value of PET / MRI for the Assessment of Lymph Node Metastasis and Other Prognostic Factors in Patients With Rectal Cancer
The combination of FDG-PET/CT and MRI at staging of rectal cancer in diagnosis is currently very little studied. The investigator have a unique opportunity to study this. Hypothetically, with PET/MR as one hybrid imaging method, alternatively as an additional method, it could increase the accuracy of rectal cancer of moderate and high risk type, especially at primary N-staging, but also in assessing other important prognostic factors such as T-staging, peritoneal involvement, metastasis to lateral lymph nodes, EMVI and MRF involvement. The same reasoning applies to the assessment of tumor regression after CRT. In the study, PET/MR is compared with PET/CT, diagnostic CT and MRI to evaluate the additional value of the hybrid imaging PET/MRI. The investigator also plan to evaluate how immunological, proliferative and prognostic biomarkers in blood and tumor tissue correlate with the radiological findings, and if the combination biomarker and radiology can provide additional prognostic information.

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.

A Phase I Study of Actinium-225 Labeled Humanized Anti-CEA M5A Antibody in Patients With CEA Producing Advanced Colorectal Cancer
This phase I study tests the safety, side effects, and best dose of Ac225-DOTA-M5A in treating patients with CEA positive colorectal cancer that has spread to other places in the body (advanced). Ac225-DOTA-M5A is a humanized monoclonal anti-CEA antibody, linked to a radioactive agent called actinium 225. M5A attaches to CEA positive cancer cells in a targeted way and delivers actinium 225 to kill them.

68Ga-FAPI-04 PET Imaging in Early Response Evaluation of Rectal Cancer Patients Treated With Immunotherapy: A Single-center Clinical Study
This study is a prospective monocentric study aimed to explore the value of 68Ga-FAPI-04 PET imaging in early response evaluation of rectal cancer patients treated with immunotherapy. Patients with histopathologically confirmed diagnosis of rectal cancer will be recruited and undergo 68Ga-FAPI-04 and 18F-FDG PET imaging before treatment and after short-course radiotherapy and two cycles of neoadjuvant chemotherapy plus immunotherapy. The two imaging intervals will be completed two days apart. The efficacy of 68Ga-FAPI-04 in early response evaluation will be compared with the general imaging agent 18F-FDG. The general information, clinical data, mpMRI data, 68Ga-FAPI-04 and 18F-FDG PET imaging results and other imaging data of the patients will be collected. The histopathology of the biopsy or surgical specimen after 2 cycles of therapy and follow-up data will be taken as evaluation references. This study plans to set the sample size as 20 cases

68Ga-NOTA-PEG2-RM26 PET/CT: Tracer Biodistribution and Uptake in Different Kinds of Cancer With Gastrin-Releasing Peptide Receptor (GRPR) Overexpression
The gastrin-releasing peptide receptor (GRPR), also known as bombesin receptor subtype II (BB2), is a member of the G protein-coupled receptor family of bombesin receptors. GRPR is over-expressed in various types of human tumors. RM26, a GRPR antagonist with high affinity, was discovered by peptide backbone modification of bombesin analogues. To target gastrin-releasing peptide receptor in human neoplastic cells NOTA-PEG2-RM26 was synthesised and then labeled with 68Ga. An open-label whole-body PET/ CT study was designed to investigate the safety and dosimetry of 68Ga-NOTA-PEG2-RM26 and to assess its clinical diagnostic value in patients with cancer.

The Safety, Tolerability and Biodistribution of a Single Intravenous Administration of Two Zirconium-89 Labelled Vartumabs (F8scFV or C9scFv) in Patients with Solid Tumors - a Phase 0, Open Label, PET/CT Molecular Imaging Basket Trial
VARTUTRACE is a first-in-human PET/CT molecular imaging study in patients with solid tumors. This study will investigate the biodistribution and pharmacology of two antibody fragments binding oncofetal Chondroitin Sulfate (CS). Oncofetal CS are tumor-specific carbohydrate motifs present in proteoglycans and identified by VAR2 Pharmaceuticals as expressed during fetal development. Oncofetal CS reappears in the vast majority of cancers while remaining largely absent from normal tissues. VAR2 Pharmaceuticals recently developed antibodies specific for oncofetal CS. VARTUTRACE uses two of these as radiolabeled antibody fragments to study biodistribution, tumor accumulation, pharmacodynamics and clearance pathways in a diverse patient population.
