This study assessed whether the expressions of both WEE1 and phosphorylated CDK1 in specimens of oral squamous cell carcinoma (OSCC) might predict the OSCC recurrence and progression. Materials and methods: This study used immunohistochemistry to examine the expressions of WEE1 and phosphorylated CDK1 proteins in 75 specimens of OSCC and 30 specimens of normal oral mucosa (NOM). Results: The mean WEE1 labeling index (LI) was significantly lower in 75 OSCC samples than in 30 NOM samples (P < 0.001), whereas the mean phosphorylated CDK1 LI was significantly higher in 75 OSCC samples than in 30 NOM samples (P < 0.001). We found a significant association of low WEE1 LI (<21%) with OSCC recurrence (P = 0.047) and a significant association of low phosphorylated CDK1 LI (<10%) with larger tumor size (P = 0.011) and more advanced clinical stages (P = 0.021) of OSCC. Conclusion: Combined evaluation of WEE1 and phosphorylated CDK1 LI in specimens of OSCC may predict the OSCC recurrence and progression. |
