Ultrasound-Guided Photoacoustic Imaging for the Detection of Metastases in Inguinal Lymph Nodes

Malignant Neoplasm Clinical Trial

Official title: The Role of Ultrasound-Guided Photoacoustic Imaging in Detection of Metastases in Inguinal Lymph Nodes

Status Active, not recruiting

Clinical Trial Summary

This early phase I trial studies how well ultrasound-guided photoacoustic imaging works in telling the difference between healthy and cancerous inguinal (groin) lymph nodes and how well it can detect certain features of lymph nodes, including size and shape in patients with cancer. Ultrasound-guided photoacoustic is a non-invasive imaging method that can detect and display characteristics of lymph nodes based on the level of oxygen in the cells. This imaging method may provide more accurate tumor staging and prevent unnecessary surgical interventions.

Clinical Trial Description

PRIMARY OBJECTIVE: I. To estimate the mean difference in oxygen saturation (%sO2) between healthy and malignant inguinal lymph nodes using ultrasound-guided photoacoustic imaging (PAI) in cancer patients. SECONDARY OBJECTIVE: I. To examine the role of ultrasound-guided PAI in detecting metastases in the inguinal lymph nodes and ultrasound features of lymph nodes such as the size, shape of the lymph nodes. OUTLINE: Patients undergo standard of care ultrasound of the lymph nodes, then undergo ultrasound-guided PAI over 3-5 minutes. Patients then undergo standard of care ultrasound-guided fine needle aspiration (FNA) or biopsy a suspicious lymph node. After completion of study, patients are followed up for 3 months. ;
