Prognostic nomogram for patients with tongue squamous cell carcinoma: A SEER ‐based study

Abstract Objectives In order to predict the patients' prognosis with tongue squamous cell carcinoma (SCC), this study set out to develop a clinically useful and trustworthy prognostic nomogram. Subjects and Methods The Surveillance, Epidemiology, and End Results (SEER) Program was used to compile clinical information on patients with tongue SCC between 2010 and 2015. The likelihood of Cancer‐Specific Survival (CSS) and Overall Survival (OS) for specific patients was predicted using a prognostic nomogram created with the help of the RStudio software. The nomogram's predictive ability was evaluated using the consistency index (C‐index) and decision curve analysis, and the nomogram was calibrated for 1‐, 2‐, 3‐, 5‐, and 10‐year CSS and OS. Results Patients numbering 6453were enrolled in this study. The primary cohort (3895) and validation cohort (2558) were each randomly assigned. Sex, age, tumor‐node‐metastasis (TNM) stage, surgery, chemotherapy, and radiation were significant risk factors for OS, whereas age, TNM stage, surgery, chemotherapy, and radiotherapy were significant risk factors for CSS. Additionally, C‐index and calibration curves indicated that the prognostic nomogram prediction and the actual observation in both cohorts would be very coherent. Conclusions The predictive nomogram created in this study can offer patients with tongue SCC customized treatment and survival risk assessment.
