Endometrial Adenocarcinoma: Analysis of Circulating Tumour Cells by RT-qPCR

Anticancer Res. 2016 Jun;36(6):3205-9.

Abstract

Background: Endometrial adenocarcinoma is a frequently occurring cancer in women, accounting for 42,000 deaths every year. Despite treatment with standard therapy, occurrence of remote metastases and local recurrences is high. Through help of RT-qPCR minimal residual disease could be detected and characterized, facilitating therapeutic decision making.

Materials and methods: A number of marker genes were first tested in model systems and genes that performed best, were consequently used for the examination of 13 blood samples from endometrial carcinoma patients.

Results: Cytokeratin 19 and MIG7 were chosen for the analysis in patient samples. Both genes were found up-regulated in small tumours and in one large tumour, but no statistical correlations could be revealed between expression levels of these two genes and tumour characteristics.

Conclusion: There seems to be a coherence between gene expression and the stage of tumorigenesis, but the number of samples is still too small, to be able to obtain statistical significant differences.

Keywords: Endometrial adenocarcinoma; circulating tumour cells; marker genes; real-time PCR.
