Real-world Evaluation of Patient Outcomes and Experiences With Ribociclib Early Adopters.

Summary

This non-interventional study (NIS) aims to evaluate effectiveness, persistence, treatment patterns, adverse events (AEs), and patient-reported experience (including adherence, treatment satisfaction, health-related quality of life \[HRQoL\], work productivity, and etc.), among HR+/HER2- stage II and III eBC patients treated with ribociclib + ET, and to evaluate AEs and patients-reported experience among HR+/HER2- stage II and III eBC patients treated with abemaciclib + ET, as per local label.

Eligibility

Inclusion Criteria:

* Males or females.

  * Tested positive for estrogen receptor (ER+), or
  * Tested positive for progesterone receptor (PR+), or
  * Tested positive for both.
* Tested negative for HER2 (HER2-) using the closest biomarker test on or before the adjuvant therapy initiation date.

Exclusion Criteria:
