This study aimed to evaluate the expression of mTOR pathway genes as a prognostic factor for distant recurrence-free survival (DRFS) in triple-negative breast cancer (TNBC). Methods: An observational, analytical, cohort, retrospective study was conducted. The study population consisted of patients from the public database GSE25066 of the Gene Expression Omnibus repository (https://www.ncbi.nlm.nih.gov/geo/) who met the eligibility criteria. The Cox regression test was used to determine the genes whose expression is associated with DRFS, and a gene signature was constructed with them by multiplying the expression value by the regression coefficient. Results: In total, 172 patients were included, 86 cases in each group. PIK3CD and RHEB genes were determined to be independent prognostic factors of DRFS, and the mTOR signature [(0.461x PIK3CD) + (0.687xRHEB)] was constructed. Using the median mTOR score (0.0592) as the cut-off point, it was determined that there are significant differences in SLRD (p=0.002); patients with high scores have a worse prognosis (HR=2.453; 95% CI: 1.435-4.194) compared to those with low scores. In addition, the mTOR signature is a prognostic factor independent of age, histological grade, and clinical stage. Conclusion: mTOR pathway genes are a prognostic factor for DRFS in TNBC.
