Are There Clinical or Pathological Parameters of Maxillary Oral Squamous Cell Carcinoma With an Influence on the Occurrence of Neck Node Metastasis? An Appraisal of 92 Patients

Purpose: To determine the proportion of patients with cervical metastases caused by maxillary oral squamous cell carcinoma (OSCC) and to identify any clinical or pathologic parameters that might be associated with the occurrence of metastatic neck disease. Materials and Methods: A retrospective cohort study of all patients managed with primary surgical resection of maxillary OSCC at the authors’ institution from 2006 through 2013 was performed. Cervical lymph node dissection and adjuvant therapy were performed as warranted by preoperative staging examinations or histopathologic evaluation or as recommended after multidisciplinary consultation, and regular follow-up protocols were followed. In this analysis, each maxillary OSCC was assigned to an anterior or a posterior anatomic group based on the location of the primary lesion, with the anatomic tumor location serving as the predictor variable and the occurrence of cervical lymph node metastases as the outcome variable. Descriptive and inferential statistics were calculated with a significance level set at a P value less than .05 and post hoc power analyses were performed.
