Abstract
Objectives: To determine the occurrence of Activated Leukocyte Cell Adhesion Molecule (ALCAM) and its predictive factors in patients with oral squamous cell carcinoma (OSCC). Methods: This cross sectional study was concocted on 102 patients with OSCC referred to Imam Khomeini Hospital of Tehran during 1997-2015. The data collection tool a checklist consisted of demographic and pathologic (lymph node involvement, differentiation, tumor size and tumor location) characteristics which extracted from patients’ medical records. To evaluate ALCAM, a new sample of tumor tissue was prepared from archive. Finally, the multivariable logistic regression model was used to determine the predictive factors of ALCAM by STATA14. Results: the number (%) of men and women were 70 (68.6) and 32 (31.4%), respectively. The mean age (S.D) of participants was 61.7 (15.6) years. Of the total samples, 32 (38.2), 19 (18.6), 36 (35.3) and 8 (7.8%) samples were related to the tongue, oral mucosa, skin and lips, respectively. More than half of the tumors had good differentiation and lymph node involvement and 74.5% were ≥20 mm. Also, 79.41% of the samples were positive for the overall incidence of ALCAM. The most important predictors of the overall incidence of ALCAM were tumor size (OR: 3.46, 95% CI: 1.71 - 7.01) and tumor location (OR: 3, 95% CI: 1.03 - 8.72). Similarly, for incidence of cytoplasmic ALCAM were age (OR: 2.56, 95% CI: 1.38 - 4.76) and location of the tumor (OR: 3.23, 95% CI: 1.08 - 9.64). However, the only predictor of membranous ALCAM incidence was lymph node involvement (OR: 0.36, 95% CI: 0.19 - 0.66). Conclusion: The results of our study suggest preliminary evidence for the potential clinical application of ALCAM as a prognostic biomarker for OSCC which may be the basis for future clinical application, however further studies are recommended.
