Background  Aromatase inhibitors (AI) reduce recurrence and death in patients with early-stage hormone receptor-positive (HR +) breast cancer. Treatment-related toxicities, including AI-induced musculoskeletal symptoms (AIMSS), are common and may lead to early AI discontinuation. The objective of this study was to replicate previously reported associations for candidate germline genetic polymorphisms with AIMSS.    Methods  Women with stage 0-III HR + breast cancer initiating adjuvant AI were enrolled in a prospective clinic-based observational cohort. AIMSS were assessed by patient-reported outcomes (PRO) including the PROMIS pain interference and physical function measures plus the FACT-ES joint pain question at baseline and after 3 and 6 months. For the primary analysis, AIMSS were defined as ≥ 4-point increase in the pain interference T-score from baseline. Secondary AIMSS endpoints were defined as ≥ 4-point decrease in the physical function T-score from baseline and as ≥ 1-point increase on the FACT-ES joint pain question from baseline. The primary hypothesis was that  TCL1A  rs11849538 would be associated with AIMSS. Twelve other germline variants in  CYP19A1 ,  VDR ,  PIRC66 ,  OPG ,  ESR1 ,  CYP27B1 ,  CYP17A1 , and  RANKL  were also analyzed assuming a dominant genetic effect and prespecified direction of effect on AIMSS using univariate logistic regression with an unadjusted α = 0.05. Significant univariate associations in the expected direction were adjusted for age, race, body mass index (BMI), prior taxane, and the type of AI using multivariable logistic regression.    Results  A total of 143 participants with PRO and genetic data were included in this analysis, most of whom were treated with anastrozole (78%) or letrozole (20%). On primary analysis, participants carrying  TCL1A  rs11849538 were not more likely to develop AIMSS (odds ratio = 1.29, 95% confidence interval: 0.55–3.07,  p  = 0.56). In the statistically uncorrected secondary analysis,  OPG  rs2073618 was associated with AIMSS defined by worsening on the FACT-ES joint pain question (OR = 3.33,  p  = 0.004), and this association maintained significance after covariate adjustment (OR = 3.98,  p  = 0.003).    Conclusion  Carriers of  OPG  rs2073618 may be at increased risk of AIMSS. If confirmed in other cohorts,  OPG  genotyping can be used to identify individuals with HR + early breast cancer in whom alternate endocrine therapy or interventions to enhance symptom detection and implement strategies to reduce musculoskeletal symptoms may be needed.
