What is it about?
Our study evaluated 119 luminal early breast cancer patients in whom preoperative Letrozole 2.5mg OD was given for a period of 2-4 weeks. The initial Ki67 was noted from the core biopsy specimen, and a post-therapy Ki67 value was obtained from the surgical specimen. The percentage fall was calculated and the factors affecting the same were analysed.

This can help differentiate between good responders and poor responders to endocrine therapy, thus allowing us to tailor adjuvant therapy for each patient
