Prognostic Significance of Regional Disease in Young Patients with Oral Cancer: A Comparative Study

Abstract

BackgroundRegional metastases are considered the most important prognostic factor in OSCC patients. We aimed to investigate the impact of regional disease among different age groups with OSCC.MethodsA retrospective comparison between patients 40 years old or younger, 41–69 years old, and 70 years or older treated for OSCC between 2000 and 2020 in a tertiary‐care center.Results279 patients were included. The mean age was 65 ± 17.7 and 133 were male (47.7%). Thirty‐six (12.9%) were 40 years old or younger, 101 (36.2%) were 41–69 years and 142 (50.9%) were 70 years or older. Five‐year overall survival and disease‐specific survival (DSS) were significantly better among patients younger than 40 compared to the mid‐age group and patients 70 years or older (76.7% vs. 69.4% vs.48.2%, Log‐rank p < 0.001, and 76.7% vs. 75.3% vs. 46.5%, Log‐rank p < 0.001, respectively). While an association between regional spread and overall survival and DSS was demonstrated among all age groups, the odds ratio (OR) for death of any cause and death of disease regarding cervical metastasis was much higher among patients younger than 40 compared with the 41–69 and 70+ age groups (death of any cause‐OR = 23, p‐value = 0.008, OR = 2.6, p‐value = 0.026, OR = 2.4, p‐value = 0.13, respectively. Death of disease‐OR = 23, p‐value = 0.008, OR = 2.3, p‐value = 0.082, OR = 4.1, p‐value = 0.001, respectively). In univariate  analysis, regional metastasis was associated with disease‐free survival only among patients younger than 40 (p‐value = 0.04).ConclusionsRegional metastases correspond with worse prognosis in young patients compared to older patients. These patients may benefit from a comprehensive treatment approach with close post‐treatment follow‐up.Level of Evidence3 Laryngoscope, 2023
