Abstract
Maxillary cancers include neoplasms arising in both maxillary sinus and oral cavity (upper alveolar ridge, hard palate) according to the American Joint Committee on Cancer. Although it is universally accepted that the combination of surgery and radiotherapy seems to be the treatment of choice, there is no accordance about the treatment of clinically negative neck. We retrospectively analyzed 20 patients with maxillary sinus cancer and 37 with an upper alveolar ridge or hard palate cancer, evaluating the incidence of N-disease and the recurrence at local site. On the basis of our findings, we can affirm that elective treatment of the neck in maxillary carcinoma is not recommended. Considering only squamous cell carcinoma, cervical node metastases are most frequent in case of tumors staged as T1 o T2. High-grade squamous cell carcinomas seem to be related to a higher incidence of nodal involvement. T recurrence has demonstrated to be the most frequent neoplastic event, so that radical surgery is considered one of the most important prognostic factors. Nevertheless, other prospective studies are necessary.
