Popis: e15133 Background: In the US, colorectal cancer is the third most common malignancy in women. Postmenopausal hormone use has been associated with decrease in incidence of colorectal cancer however few studies have evaluated the relationship between hormone use and molecular profiles of advanced colorectal cancer. The aim of this study is to evaluate correlations between female hormonal supplementation use and colorectal cancer molecular, clinical, and pathologic features. Methods: We conducted a retrospective case-case study of female patients with metastatic or unresectable, locally advanced colorectal cancer on the Assessment of Targeted Therapies Against Colorectal Cancer (ATTACC) protocol from 2010 to 2017. Post-menopausal hormone use was self-reported in an environmental survey as part of the ATTACC protocol. Molecular, clinical, and pathologic features were obtained through medical record review. Results: Among 258 female patients, 163 (63%) patients reported ever use of female hormonal supplementation. Ever use was significantly associated with BRAF V600E mutant tumors (OR 2.63, p-value 0.04). There was no association with KRAS, NRAS, PIK3CA mutations, microsatellite instability, or CpG island methylation. The mean age at diagnosis of ever users was 54.4 and mean of no supplement was 56.5 (p-value 0.07), indicating no age difference between ever and never users. Conclusions: Despite the overall protective effects of postmenopausal hormone use on colorectal cancer incidence, among those who develop colorectal cancer, our data suggest an association between female hormonal supplementation and BRAF mutation. Further studies are needed to evaluate this relationship in additional cohorts, interrogate the biological basis, and identify whether there is an association with survival of patients with metastatic or locally advanced colorectal cancer with estrogen or progestin supplement use.
