Background: The Union for International Cancer Control and American Joint Committee on Cancer tumor staging system is used globally for treatment planning. As it may be insufficient for tumor staging of lower gingival carcinomas, we proposed the mandibular canal tumor staging system. In this study, we aimed to compare the two systems for such tumor staging and to identify prognostic markers.

- The 8th edition of the cancer staging system incorporates depth of invasion (DOI) and extranodal extension (ENE) for assessing oral cavity cancer, enhancing its prognostic accuracy compared to the 7th edition.
- A review of 2,118 patients showed that the new system allowed for a significant number of cases to be upstaged, leading to better differentiation and understanding of the disease's progression.
- Overall, the updated staging system improved survival prediction and highlighted patients at higher risk of mortality, making it a more effective tool for clinicians.
Background: The purpose of this retrospective study was to investigate the prognosis of patients with oral cavity cancer with positive margin (PM) or close margin (CM) divided into pN- and pN+ groups.
Methods: The evaluated endpoints were local control and disease-specific survival (DSS) rates.
Results: Higher T classification, lymphovascular space invasion (LVSI), and older age were significant risk factors for DSS in the pN- groups.
The association between the pretreatment body mass index (BMI) and oral squamous cell carcinoma (SCC) outcomes is controversial. We aimed to examine the association between BMI and cause-specific mortality due to cancer of the oral cavity and patterns of failure that correlate with increased mortality. We enrolled 2,023 East Asian patients in this multicenter cohort study.

- A multicenter retrospective study examined 69 patients with mucosal malignant melanoma (MM) of the oral cavity in Japan to analyze demographics and treatment outcomes from 2000 to 2020.
- The study found that most patients were older men, with a mean age of about 70, and many had advanced disease stages, with 79.7% undergoing radical therapy.
- Results indicated that early detection and radical treatment significantly improved survival rates, highlighting advanced T classification as a key prognostic factor for overall survival.
