Abstract
The authors have tried to verify whether some clinical or pathological features of laryngeal cancer may favor the occurrence of occult metastases in the lymph nodes of the neck in N0 cases. The purpose of the investigation was to define the possible existence of tumors, where elective neck dissection, in the absence of palpable nodes, could be done without, thus contributing to settlement of a long debated problem. Different parameters, both clinical and pathological, have been considered. The result of a cross comparison of such parameters in 237 cases of cancer of the larynx without palpable nodes, submitted to surgery on the primary and elective neck dissection, indicates that, although the frequency of occult metastases is significantly related to the site and size of the tumor, its grading, and the degree and type of stromal reaction, the favorable concurrence of all said parameters occurs in 2% of cases only. However, if only clinical parameters, viz. site and size of tumor, are taken into account, a favorable concurrence occurs in 18% of cases with an incidence of occult metastases lower than 2%. These cases are almost exclusively represented by T1N0 supraglottic and T2N0 glottic tumors. We can conclude by saying that clinical and pathological preoperative findings may offer a useful clue in evaluating the risk of occult metastases, and hence advising, or not, an elective neck dissection in N0 cases. Nevertheless, in the vast majority of cases, an elective functional neck dissection still offers the best guarantee of oncologic safety while avoiding unnecessary mutilation.Keywords
