Management of occult neck metastases in oral cavity squamous carcinoma

Abstract

A large experience with patients who had radical neck dissection for oral squamous carcinoma has been reviewed in order to compare elective lymphadenectomy results with those achieved when neck dissection was delayed until metastases appeared or was performed initially for limited N1 neck disease. No significant difference in survival rates was observed, but neck failure was a more significant problem when treatment was delayed. This was most obvious in patients treated for tongue cancer. Although the impact of elective neck treatment on "cure" rates will require prospective studies, it seems clear that elective lymphadenectomy can enhance regional control of cancer and improve the quality of the patients' survival.
