摘要
Background: Enterococci role in the microbiome remains contro-versial, and researches regarding enterococcal infection (EI) and its sequelae are limited. The gut microbiome has shown to play an im-portant role in immunology and cancer. Recent data have suggested a relationship between the gut microbiome and breast cancer (BC). Methods: Patients in a Health Insurance Portability and Account-ability Act (HIPAA) compliant national database (2010 -2020) were used for this retrospective study. International Classification of Dis-ease (ICD) Ninth and Tenth Codes, Current Procedural Terminology (CPT), and National Drug Codes were used to identify BC diagnosis and EI. Patients were matched for age, sex, Charlson comorbidity index (CCI), antibiotic treatment, obesity, and region of residence. Statistical analyses were implemented to assess significance and esti-mate odds ratio (OR).Results: EI was associated with a decreased incidence of BC (OR = 0.60, 95% confidence interval (CI): 0.57 -0.63) and the difference was statistically significant (P < 2.2 x 10-16). Treatment for EI was controlled for in both EI and noninfected populations. Patients with a prior EI and treated with antibiotics were compared to patients with no history of EI and received antibiotics. Both populations subse-quently developed BC. Results remained statistically significant (P < 2.2 x 10-16) with an OR of 0.57 (95% CI: 0.54 -0.60). In addition to standard matching protocol, obesity was controlled for in both groups by exclusively containing obese patients, but one group with prior EI and the other without. In obese patients, a lower incidence of BC was shown in the infected group compared to the noninfected group.Results were statistically significant (P < 2.2 x 10-16) with an OR of 0.56 (95% CI: 0.53 -0.58). Age of BC diagnosis with and without a prior EI was analyzed and demonstrated increased BC incidence with increasing age in both groups, but less in the EI group. Incidence of BC based on region was analyzed, which showed lower BC incidence across all regions in the EI group.Conclusion: This study shows a statistically significant correlation between EI and decreased incidence of BC. Further exploration is needed to identify and understand not only the role of enterococcus in the microbiome, but also the protective mechanism(s) and impact of EI on BC development.
