Abstract
Background and objective: Tongue squamous cell carcinoma (TSCC) is the most prevalent oral cancer. Despite considerable advancements in treatment, the 5-year survival rate remains relatively unchanged. Langerhans cells (LCs) play an important role in antitumor immunity. Therefore, we attempt to evaluate the correlation between the LC count and disease prognosis.
Materials and methods: Histopathologic slides from 24 cases, with at least 2 years of follow-up, were selected and categorized into early-stage (12 cases) and advanced-stage (12 cases) groups. An additional 12 slides of normal tissue comprised the control group. Immunohistochemical staining with the CD1a marker was performed to analyze the density of LCs. Statistical analysis assessed the impact of CD1a immune expression on patient survival and other variables such as age, gender, stage, and histopathological grade.
Results: Comparison of CD1a+ cell counts across the three groups revealed a significant decrease in the advanced group. Furthermore, a lower count of CD1a+ cells correlated with poorer disease-free survival (DFS) (p < 0.001) and overall survival (OS) (p = 0.049). Although the CD1a+ cell count did not independently affect OS significantly (p = 0.210), it did show a significant impact on DFS as an independent variable (p = 0.002).
Conclusion: The significant correlation between CD1a expression and patients' prognosis and survival rates suggests that CD1a+ cells could serve as a crucial prognostic factor in the management and treatment of TSCC.
期刊介绍：
Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
