Brief summary: CORALLEEN is a two-arm, randomized, multicentric study in postmenopausal women with primary HR+/HER2 negative Luminal B breast cancer that will explore if the combination of ribociclib with letrozole offers clinical benefit at least comparable to that of standard chemotherapy.

Detailed description: This is a parallel, two-arm, randomized 1:1, stratified by tumor size and nodal involvement, open-label, multicenter, exploratory study in postmenopausal women with primary operable HR+/HER2-negative Luminal B breast cancer according to PAM50 intrinsic subtype to evaluate the clinical benefit and biological effects of ribociclib combined with letrozole.

The primary trial objective is to evaluate the ability of each treatment strategy to provide ROR-low score at surgery.

Luminal B patients will be randomized 1:1 to either letrozole plus ribociclib or chemotherapy.Two weeks after the first administration of the assigned treatment, patients will undergo a biopsy to assess early biological response to treatment, at Ki67 protein and gene expression level. After finalization of the assigned neoadjuvant treatment, patients will undergo surgery.

The primary endpoint, Rate of ROR-low (at surgery) after neoadjuvant treatment, according to the Prosigna test will be centrally assessed.

Baseline, Day 15 and post-treatment (surgical) primary breast tumor tissue samples should be available for each patient for molecular characterization A post-surgery visit will be performed within 28 days (7 days) from surgery, and will mark the end of the study for that patient

Eligibility criteria: Inclusion Criteria

1. Signed Informed Consent Form prior to any study-specific procedure.
2. Female patients.
3. Post-menopausal status and age ≥18 years.
4. Histologically confirmed invasive breast carcinoma, with all the following characteristics:

   * Primary tumor ≥ 2cm in largest diameter as measured by breast MRI

   * No evidence of distant metastasis (M0)
5. Breast cancer eligible for primary surgery.
6. Available pre-treatment FFPE core (Tru-cut) biopsy evaluable for PAM50 or possibility to obtain one. Minimal sample requirements are to have at least 2 tumor cylinders with a minimal tissue surface of 10 mm2 tissue, containing at least 10% tumor cells and having enough tissue to do at least 2 cuts of 10 micrometers each.

8. ER-positive and/or PgR-positive and HER2-negative tumor by ASCO/CAP guidelines assessed locally.
9. In the case of a multifocal tumor (defined as the presence of two or more foci of cancer within the same breast quadrant), the largest lesion must be ≥ 2 cm and designated the "target" lesion for all subsequent tumor evaluations and HR+/HER2-negative status must be documented in all the tumor foci.
10. ECOG performance status of 0 or 1.

16. Known human immunodeficiency virus (HIV) infection.
17. Any other diseases, active or uncontrolled pulmonary dysfunction, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug, that may compromise compliance with the protocol, that may affect the interpretation of the results, or renders the patients at high risk from treatment complications.
18. Significant traumatic injury within 3 weeks prior to initiation of study treatment.
19. Major surgical procedure (not including minor procedures such as lymph node biopsy, tumor core biopsy, fine needle aspiration) within 4 weeks prior to initiation of study treatment or not fully recovered from any side effects of previous procedures.
20. Any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule.
