AIMS: This study was conducted to analyze the clinical significance of ASAP1 in epithelial ovarian cancer (EOC).

METHODS: A total of 95 patients with EOC were included in the study. The expression profile of ASAP1 in 10 pairs of ovarian cancer and normal ovary tissues were detected by Real-time PCR. The expression level of ASAP1 in 95 paraffin-embedded EOC specimens was measured by immunohistochemistry staining. Statistical analysis was performed to evaluate the clinicopathologic significance of ASAP1.

RESULTS: Levels of ASAP1 mRNA were higher in EOC than in normal ovary tissues. Patients with higher ASAP1 expression had shorter overall (P=0.019) and recurrence-free (P=0.030) survival time, whereas those with lower ASAP1 expression survived longer. In addition, high expression of ASAP1 was correlated with poor overall (P=0.044) and recurrence-free (P=0.006) survival in patients with advanced carcinomas. Moreover, statistical analysis displayed a significant correlation in ASAP1 expression with pelvic metastasis (P=0.015). Multivariate analysis revealed that an elevated ASAP1 expression was a significant independent prognostic factor for the overall (P=0.039) and recurrence-free (P=0.028) survival of EOC patients.

CONCLUSION: These results indicated that elevated expression of ASAP1 plays an important role in the progression and metastasis of ovarian cancer, and that ASAP1 may be used as a biomarker in predicting patient outcome in EOC patients.
