Role of modern imaging in decision-making for elective neck dissection.
This study examines patterns of early metastatic spread as recorded in 19 clinically negative, histologically positive (occult) neck dissection specimens. Microscopic metastatic deposits were detected in this study in nodes measuring 10 mm and less. No nodes with extension of tumor beyond the capsule and into adjacent structures were noted. Central necrosis was detected in only one node. We suggest that the first stages of metastatic disease as evaluated by the pathologist in clinically occult nodes are minimal and may easily evade the eyes of both pathologists and radiologists. Imaging proved to be efficacious in upstaging clinically occult necks that were previously irradiated.
