SEGURA MORENO, Yenifer Yamile e SERRANO LOPEZ, Martha Lucía. Protocol Standardization for Detection of TMPRSS2 Fusions: ERG and Gene Expression of EZH2, SPINK-1 and NKX3.1 in Prostate Cancer (PCa). Acta biol.Colomb. [online]. 2016, vol.21, n.3, pp.533-542. ISSN 0120-548X. https://doi.org/10.15446/abc.v21n3.50477.
At present doesn't exist tool to differentiate patients with prostate cancer (PCa) of poor prognosis of those with indolent disease that only require a controlled monitoring of the disease. Because of the coexistence of different premalignant and malignant foci in CaP, the understanding of the carcinogenesis process requires a better understanding. Currently, the morphological heterogeneity in PCa is evaluated with Gleason score, which is closely related to the prognosis of the disease, but this is insufficient so it is currently to work on identifying molecular alterations to identify subtypes that can establish more precisely the patient's prognosis. This preliminary study aimed to standardization of the method of quantification in prostatic samples of FFPE of expression of transcripts of possible biomarkers, such as the oncogenes, SPINK-1 y EZH2, the tumour suppressor, NKX3.1, together with the determination of the presence/absence of gene fusion, TMPRSS2:ERG, being that these transcripts are involved in apparent exclusive events of the natural evolution of PCa, that support the possibility of a molecular classification for this disease.
