MSLN (Margin Status in Lymph Node)

MSLN, or Margin Status in Lymph Node, refers to whether cancer cells have spread to nearby lymph nodes and if those nodes are free of cancer or not. It's an important factor in cancer staging and treatment planning. A “negative” status means no cancer found in the lymph nodes, indicating a potentially better prognosis. A “positive” status indicates cancer presence, suggesting a higher chance of spread and may influence additional treatment decisions. MSLN helps doctors understand the extent of the disease and determine the most appropriate care.
