Dye is injected into the breast, one to four of the nodes is identified with a probe and removed to see if cancer cells are present. Lymph nodes are small organs, typically ranging from the size of a ...

Trials evaluating the omission of completion axillary-lymph-node dissection in patients with clinically node-negative breast cancer and sentinel-lymph-node metastases have been compromised by limited ...

Sentinel-lymph-node biopsy is associated with increased melanoma-specific survival (i.e., survival until death from melanoma) among patients with node-positive intermediate-thickness melanomas (1.2 to ...

Tumors, such as melanoma, release nanovesicles called exosomes (gray) that travel and lodge in the lymph nodes. There they corrupt the behavior of lymph cells. The lymphatic vessels (green) branch out ...

Importantly, the sentinel nodes are evaluated intensively using serial sectioning and a combination of routine histopathology and immunohistochemistry staining for melanoma-associated antigens such as ...

The Melanoma Institute of Australia (MIA) previously developed a risk calculator for sentinel lymph node (SLN) metastasis risk to help clinicians and patients with primary cutaneous melanoma decide ...

The intraoperative molecular tests (RD‑100i OSNA system and Metasin test) are used during breast cancer surgery to detect the presence of 1 or 2 biological markers that are associated with metastatic ...
