Resum: We aimed to evaluate the prognostic and predictive value of the nucleotide excision repair-related gene GTF2H5, which is localized at the 6q24. 2-26 deletion previously reported by our group to predict longer survival of high-grade serous ovarian cancer patients. In order to test if protein levels of GTF2H5 are associated with patients' outcome, we performed GTF2H5 immunohistochemical staining in 139 high-grade serous ovarian carcinomas included in tissue microarrays. Upon stratification of cases into high- and low-GTF2H5 staining categories (> and ≤ median staining, respectively) Kaplan-Meier and log-rank test were used to estimate patients' survival and assess statistical differences. We also evaluated the association of GTF2H5 with survival at the transcriptional level by using the on-line Kaplan-Meier plotter tool, which includes gene expression and survival data of 855 high-grade serous ovarian cancer patients from 13 different datasets. Finally, we determined whether stable short hairpin RNA-mediated GTF2H5 downregulation modulates cisplatin sensitivity in the SKOV3 and COV504 cell lines by using cytotoxicity assays. Low expression of GTF2H5 was associated with longer 5-year survival of patients at the protein (hazard ratio [HR], 0. 52; 95% CI, 0. 29 to 0. 93; p=0. 024) and transcriptional level (HR, 0. 80; 95% CI, 0. 65 to 0. 97; p=0. 023) in high-grade serous ovarian cancer patients. We confirmed the association with 5-year overall survival (HR, 0. 55; 95% CI, 0. 38 to 0. 78; p=0. 0007) and also found an association with progression-free survival (HR, 0. 72; 95% CI, 0. 54 to 0. 96; p=0. 026) in a homogenous group of 388 high-stage (stages III-IV using the International Federation of Gynecology and Obstetrics staging system), optimally debulked high-grade serous ovarian cancer patients. GTF2H5- silencing induced a decrease of the half maximal inhibitory concentration upon cisplatin treatment in GTF2H5 -silenced ovarian cancer cells. Low levels of GTF2H5 are associated with enhanced prognosis in high-grade serous ovarian cancer patients and may contribute to cisplatin sensitization.
