        This study was performed to investigate the correlation between the primary squamous cell carcinoma in oral cavity (POSCC) and paired metastatic oral squamous cell carcinoma in cervical lymph node (MOSCC) via immunohistochemical staining with Ki-67 and p53. The subjects included ten patients (20 specimens) who were diagnosed with OSCC with metastatic lymph nodes from 2010 to 2015 and surgically treated involving neck dissection in Kyungpook National University Hospital. Twenty specimens were stained immunohistochemically with Ki-67 and p53. The degrees of immunostaining by Ki-67 and p53 was evaluated as 0 (no positive cells), weak (1~25% positive cells), moderate (26-50% positive cells) and strong (>50% positive cells). Despite the strong tendency, there was no statistically significant result between expressions of Ki-67 and p53 in POSCC or MOSCC. We found that high expression of Ki-67 was significantly correlated with poor degree of differentiation. Our results suggest that expression of Ki-67 may be a predictable factor for degree of differentiation of POSCC and MOSCC.
