Summary

Detection of lymph nodes starting to be involved by cancer spreading from the thyroid gland during operation is useful. It saves the patient from having a second operation to remove these nodes later on when they become obvious. The problem is that there are many lymph nodes around the gland. The theory is that only one node will get the first spill of the tumour cells.

In this study the investigators are trying to use an inert colored material to inject into the tumour. This should run in the same path as the tumour cells and should therefore stain the one lymph node that will be affected first should the tumour spread.

The stained lymph node is excised and examined instantaneously for tumour affection. If it is found to be affected by the tumour, then the operation is extended to include removal of all its fellow lymph nodes. If it is found to be free from the tumour, then this patient does not have tumour spread.

Conditions

Interventions

PROCEDURE

detecting lymph node metastasis by staining

this started by collar incision, development of sub-platysmal skin flaps and separation of strap muscles in the midline. This was followed by exposure of the thyroid gland; identification of the thyroid tumour; injection of the dye into the tumour; waiting for the dye to reach the lymph nodes; identifying the stained node; labeling it as the sentinel node (SLN); performing total thyroidectomy and bilateral central neck dissection.
