[MICROSATELLITE INSTABILITY AND SURVIVAL IN PATIENTS WITH ENDOMETRIAL CANCER.]

Microsatellite-unstable genotype associated with deficiency mismach repaired enzymes leads to the accumulation of a series of mutations in the coding and regulatory regions of the genes having a role in carcinogenesis in endometrial cancer (ECs). The aim of this study was to investigate the correlation between the expression of four main mismach repaired enzyme (MLH-1, MSH-2, MSH-6 and PMS-2) with patients survival. ECs from 70 women (median of 63 years, range of 43-79 years) were assessed immunohistochemically for microsatellite instability (MSI). In our study we found that the presence of MSI, determined by the absence of immunohistochemically expression of at least one of the test four of the enzyme mismach repaired system is associated, not statistically significant, with longer survival (p = 0.558). In conclusion we may state that the immunohistochemical analysis who indicates MSI in biopsy tissue is a one step forward for the determination of survival and progression of endometrial carcinoma.
