Purpose:
To determine the interrelationships of p53, MDM2, and p14(ARF) protein expression in primary esophageal squamous cell carcinoma (ESCC) and their prognostic value in ESCC.
Methods:
In total, 119 patients treated for ESCC with esophagectomy were enrolled in this study. Demographic and clinical data including gender, age, depth of tumor invasion, lymph node involvement, and 5-year survival rate were collected by chart review. p53, MDM2, and p14(ARF) were detected immunohistochemically in the resected tumors to evaluate their usefulness as biomarkers of clinical outcome.
Results:
p53, MDM2, and p14(ARF) were expressed in 61 (51.3%), 34 (28.6%), and 22 (18.5%) of 119 tumor specimens, respectively. Overall, p53 protein expression was positively correlated with MDM2 (P = 0.024) and p14(ARF) expression (P = 0.026). In addition, p14(ARF) expression was most often found in specimens that were positive for both p53 and MDM2. Changes in the p53, MDM2, and p14(ARF) protein levels were not correlated with 5-year survival rate.
Conclusions:
Expression of p53 protein correlates with increased MDM2 and p14(ARF) protein levels in ESCC. In addition, status of p53 (wild-type versus mutant) rather than expression level of p53, MDM2, or p14(ARF) is likely to be the more critical determinant of clinical outcome.
