Increased CD103+ T lymphocytes in lymph nodes as a marker of metastasis from non-haematopoietic malignancies

A simple blood test marker identifies hidden cancer spread in lymph nodes with near-perfect accuracy, enabling earlier detection.

Elevated CD103+ T cells in lymph node flow cytometry can distinguish metastatic carcinoma from benign/lymphoma conditions with near-perfect specificity. This simple flow cytometry marker could serve as an early alert for occult solid tumor metastasis during routine lymph node workups.
