Purpose : To determine the incidence and Prognostic effect of p53 expression in
Patients with advanced suprag1ottic cancer.
Materials and Methods ; Twenty-one cases of total 48 advanced supraglottic cancer
Patients who received postoperative adjuvant radiation therapy were evaluated by
immunohistochemical staining employing p53 monoclonal antibody.
Result : Three out of six stave ¥² Patients and four out of fifteen stage ¥³ patients
showed p53 expression without statistically significant difference(p=0.608) Five year
survival rates are 93% in P53 negative, 86% in 53 positive patients and there was no
significant difference(P=0.776). p53 expression does not show statistically significant
correlation with primary tumor status(p= 0.877), lymph node status(¥â=0.874) and age(P=
0.64).
Conclusion : There was no statistically no statistically significant correlation between
traditionally known risk factors and p53 expression.
