| Sumario: | Objective: Cytoreductive surgery as a basis of therapy in epithelial ovarian carcinomas (EOC) provides the primary tumor and metastatic tumor samples from a same patient. This gives an excellent opportunity for evaluation of metastatic factors by excluding inter-individual differences. Therefore, we aimed to define changes at mRNA levels of NM23-H1, KAI1 and MKK4 metastasis-related genes in the paired normal tissue, primary tumor and omental metastatic tumor samples obtained from a same patient. Material and Methods: mRNA levels were quantified by quantitative reverse transcription polymerase chain reaction (Q-RT-PCR) following total RNA extraction in normal tissues, primary malign tissues of EOC, and its metastatic lesions on omentum for 41 patients with stage III-C (FIGO) EOC. Results: We found that mRNA level of NM23-H1 was significantly higher in metastatic samples compared to primary tumors (p=0.009). On the other hand, MKK4 was found to be significantly lower in primary tumor samples compared to normal tissues (p=0.024). There was no significant change at mRNA level of KAI1 among normal tissues, primary tumors and omental metastatic tumor samples. Conclusion: We suppose that in detailed functional studies, approaches that suppress NM23-H1 gene and restore MKK4 gene would make these genes important molecular targets for treatment of metastatic EOC in the future.
