How Image-Guided Pathology Can Improve the Detection of Lymph Node Metastases in Prostate Cancer.

Clin Nucl Med 2022 Jun 19;47(6):559-561. Epub 2022 Apr 19.

From the Department of Medical Imaging, Nuclear Medicine.

Abstract: Detection of lymph node (LN) metastases in prostate cancer (PCa) is pivotal for accurate staging and determining treatment options. To date, the reference standard for nodal staging is histopathological examination of all harvested surgical specimens from extended pelvic LN dissections. However, this is a labor-intensive process, and small metastatic foci can be missed due to sampling effects. Read More
