What is the Sentinel Lymph Node Technique (SLN)?

The sentinel lymph node (SLN) technique is a minimally invasive procedure used to determine if the cancer has spread from the primary site to the lymph nodes. It involves the injection of a green dye ICG (indocyanine green) in the cervix to identify sentinel lymph nodes, which are the first lymph nodes where cancer is likely to spread.

Where does the technique apply?

In endometrial cancer, the SLN technique can be used to determine whether the cancer has spread beyond the uterus and to identify the lymph nodes that are most likely to contain cancer cells. The SLN technique is commonly used in cases of early-stage endometrial cancer where the risk of lymph node involvement is low to moderate.

What are the benefits of the technique?

The SLN technique has many advantages over traditional lymphadenectomy, which involves the systematic removal of a larger number of lymph nodes. The SLN technique is less invasive, has fewer complications and allows for staging of the cancer. It also reduces the risk of lymphedema, a condition in which excess fluid builds up in the hands or feet due to damage to the lymphatic system. However, the SLN technique is not suitable for all cases of endometrial cancer and the decision to use this technique should be made by your doctor in consultation with you. The benefits and risks of the SLN technique, as well as alternative treatment options, should be carefully considered before a decision is made.
