Spots Global Cancer Trial Database for Panitumumab-IRDye800 and 89Zr-Panitumumab in Identifying Metastatic Lymph Nodes in Patients With Squamous Cell Head and Neck Cancer

Study Description

Brief Summary: This study evaluates how well panitumumab-IRDye800 and 89Zr-panitumumab work in identifying cancer that has spread to the lymph nodes in patients with squamous cell head and neck cancer. Panitumumab-IRDye800 is a drug that contains a dye molecule that fluoresces during surgery to indicate cancerous tissue. 89Zr-panitumumab is a drug that contains a small amount of radiation, which makes it visible in positron emission tomography (PET) scans. PET scans make detailed, computerized pictures of areas inside the body where the drug is used. Giving panitumumab-IRDye800 and 89Zr-panitumumab to patients with head and neck cancer may help doctors find metastatic lymph nodes better than current methods \[positron emission tomography (PET); computed tomography (CT); magnetic imaging resonance (MRI), or combinations\].

Detailed Description: For patients with head and neck cancer, detection of malignant cells within nearby lymph nodes (LNs) is an important measure of the extent and severity of the cancer. LNs are a key immunologic organ involved in overall immune surveillance. Historically, LN or LNs were harvested before the surgery of curative intent, evaluated pathologically, and then tumor status of the harvested LNs were utilized to inform the individual surgical plan. These LNs became known as "sentinel lymph nodes." In recent years, techniques have been developed to utilize peritumoral injection (around the tumor) of tumor labels that could identify tumor in the LNs without biopsy, ie, only LNs that were tumor-positive would be removed. However, in some patients, this technique could be limited by the location of the primary cancer. Effective and sensitive systemically-administered labels would be a significant advancement. The systemically-administered label 18F-fluorodeoxyglucose (18F-FDG), detected by positron emission tomography / computed tomography (PET/CT) and/or PET / magnetic imaging resonance (PET/MRI) radiologic scans and representing current regular medical care, has provided improvement in detection of cancer-positive LNs. However, further enhancements may be possible. Participants with squamous cell carcinoma of the head and neck (SCCHN) and scheduled to undergo regular medical care surgery with curative intent, were assigned to 2 study groups on the basis of whether regular medical care scans using 18F-FDG PET/CT or PET/MRI had indicated that cancer was suspected in the lymph nodes (LN+ or cN+), or without suspected cancer in the lymph nodes (LN- or cN0). Following the 18F-FDG, and prior to surgery, 89Zr-panitumumab was systemically administered by intravenous infusion, and a PET-CT imaging scan was conducted. Research imaging will be performed intraoperatively using optical imaging devices and a high-energy gamma probe. Subsequently, the excised tissue will evaluated ex vivo (back table) using radioactive (89Zr-panitumumab) and fluorescence (panitumumab-IRDye800) imaging techniques. Regular medical care surgical excision of the tumor and adjacent LN was conducted on Day 2 to 5. After surgery, patients are followed up at 15 and 30 days. PRIMARY OBJECTIVES: I. Determine the sensitivity and specificity of zirconium(89Zr)-panitumumab (89Zr-panitumumab) for the detection of tumor-involved regional lymph nodes. SECONDARY OBJECTIVES: I. Determine the number (proportion) of lymph nodes determined to be tumor positive by histological and/or pathological evaluation that were NOT predicted tumor-positive by 89Zr-panitumumab labeling. EXPLORATORY OBJECTIVES: I. Determine the sensitivity and specificity of panitumumab-IRDye800 for the detection of tumor-involved regional lymph nodes. II. Determine the number (proportion) of lymph nodes determined to be tumor positive by histological and/or pathological evaluation that were NOT predicted tumor-positive by panitumumab-IRDye800 labeling.
