Metastatic and sentinel lymph node mapping using intravenously delivered Panitumumab-IRDye800CW.

Theranostics 2021 24;11(15):7188-7198. Epub 2021 May 24.

Department of Otolaryngology - Division of Head and Neck Surgery, Stanford University School of Medicine, Stanford, CA, United States.

Sentinel lymph node biopsy (SLNB) is a well-established minimally invasive staging procedure that maps the spread of tumour metastases from their primary site to the regional lymphatics. Currently, the procedure requires the local peri-tumoural injection of radiolabelled and/or optical agents, and is therefore operator dependent, disruptive to surgical workflow and restricted largely to a small subset of malignancies that can be readily accessed externally for local tracer injection. The present study set out to determine whether intravenous (IV) infusion of a tumor-targeted tracer could identify sentinel and metastatic lymph nodes (LNs) in order to overcome these limitations.

High endothelial venules (HEVs) in immunity, inflammation and cancer.

Angiogenesis 2021 May 6. Epub 2021 May 6.

Institut de Pharmacologie et de Biologie Structurale, IPBS, Université de Toulouse, CNRS, UPS, Toulouse, France.

High endothelial venules (HEVs) are specialized blood vessels mediating lymphocyte trafficking to lymph nodes (LNs) and other secondary lymphoid organs. By supporting high levels of lymphocyte extravasation from the blood, HEVs play an essential role in lymphocyte recirculation and immune surveillance for foreign invaders (bacterial and viral infections) and alterations in the body's own cells (neoantigens in cancer). The HEV network expands during inflammation in immune-stimulated LNs and is profoundly remodeled in metastatic and tumor-draining LNs. Read More

CD169 lymph node macrophages have protective functions in mouse breast cancer metastasis.

Cell Rep 2021 Apr;35(2):108993

Institute of Pharmaceutical Sciences, ETH Zurich, Zurich, Switzerland. Electronic address:

Although the contribution of macrophages to metastasis is widely studied in primary tumors, the involvement of macrophages in tumor-draining lymph nodes (LNs) in this process is less clear. We find CD169 macrophages as the predominant macrophage subtype in naive LNs, which undergo proliferative expansion in response to tumor stimuli. CD169 LN macrophage depletion, using an anti-CSF-1R antibody or clodronate-loaded liposomes, leads to increased metastatic burden in two mouse breast cancer models. Read More
