Purpose: The aim of this study was to clarify the role of VEGF expression as an independent prognostic factor and to identify the patients at high risk for poor prognosis in stage IB cervical cancer. Materials and methods: A total
of
118
patients with stage IB cervical cancer who had radical hysterectomy and pelvic lymph node dissection were included in the study. All known high risk factors of the patients were pathologically confirmed from the surgical specimen. Of the 118
patients,
88 patients were treated with postoperative radiotherapy and/or chemotherapy. VEGF expression was examined using immunohistochemistry in formalin-fixed, paraffin-embedded specimens of post-hysterectomy surgical materials. A semiquantitative
analysis was
made using a scoring system of 0, £«, £«£«, and £«£«£« for increasing intensity of stain. We classified the patients with scores from 0 to £«£« as low VEGF expression and the patients with a score of £«£«£« as high VEGF expression.
Results:
Of
the 118 patients, 35 patients (29.7%) showed high VEGF expression. Strong correlations were found between the high VEGF expression and both deep stromal invasion (p=0.01) and the positive pelvic node (p=0.03). The 5-year overall and disease-free
survival rates for all 118 patients were 95.5% and 93.8%. The 5-year overall (p=0.03) and disease-free survival (p<0.001) rates were 98.5% and 100% for low VEGF expression (0, £«, and £«£«) and 85.5% and 79.7% for high VEGF expression,
respectively.
Pelvic and distant failures for low versus high VEGF expression were 1.2% versus 17.1%, (p=0.001) and 0% versus 14.3% (p<0.001), respectively. In a Cox multivariate analysis of survival, the high VEGF expression (p=0.02) and the bulky mass
(p=0.02)
were
significant prognostic factors for overall survival. The high VEGF expression (p=0.002), and bulky mass (p=0.01) demonstrated as significant prognostic indicators for disease free survival. Conclusion: These results showed that VEGF
expression
was a highly significant predictor for pelvic and distant failure and the most significant prognostic factor of overall and disease free survival for the patients with stage IB cervix cancer treated with radical surgery. We strongly suggest that
the
immunohistochemistry for VEGF expression be performed in a routine clinical setting in order to identify the patients at high risk for poor prognosis in early stage cervical cancer. Furthermore, postoperative and/or chemotherapy did not reduce
the
pelvic failure and distant metastasis. To improve the cure rate for the patients with high VEGF expression in stage IB cervical cancer, antiangiogenic therapy including anti-VEGF Ab may be a new treatment option.
