1. Women with newly diagnosed and histologically proven de novo adenocarcinoma of the breast, Any T, any N, with at least one metastatic site measurable and/or non-measurable according to Response Evaluation Criteria In Solid Tumours (RECIST) v1.1 and/or PET Response Criteria in Solid Tumours (PERCIST) v1.0 and/or MD Anderson bone response criteria (MDA criteria). For patients with only bone metastases, at least one lytic and non-irradiated lesion must be present NB: Bilateral breast cancer is allowed only if tumours present similar histological criteria (morphological subtype, ER and HER2 status).
2. Estrogen Receptor (ER)-positive and HER2-negative breast cancer. To be considered as ER-positive, the biopsy of the primary tumour must display at least 10% of cancer cells with positive ER staining. HER2-positive is defined as IHC3+ or FISH/CISH amplified according to 2018 criteria
3. Age ≥18 years
4. Eastern Cooperative Oncology Group (ECOG) ≤2
5. Indication for treatment with palbociclib and letrozole (with or without ovarian suppression)
6. Diagnostic FFPE tumour sample and/or frozen primary breast tumour sample available
7. Women of childbearing potential must have a negative serum or urine pregnancy test done within 14 days before inclusion
8. Patients must agree to use adequate contraception methods for the duration of the study and for within 21 days after completing treatment
9. Willingness and ability to comply with scheduled visits, treatment plan, laboratory tests, and any protocol-related procedures including absence of co-morbidities preventing surgery and or radiotherapy and any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule. Those conditions should be discussed with the patient before registration in the trial
10. Patient affiliated to a social security system
11. Written informed consent obtained prior to performing any protocol-related procedures including screening evaluations
1. Patients with advanced, symptomatic, visceral spread at a risk for short-term,
life-threatening complications according to investigator judgement and at risk for
visceral crisis as defined by ABC4*
2. Women with previously diagnosed and treated ipsilateral adenocarcinoma of the breast
3. Women with previously treated or concomitant contralateral breast cancer except for
Ductal carcinoma in situ (DCIS) treated with curative intent
4. Patients with another concomitant cancer
5. Concurrent enrolment in another clinical trial in which investigational therapies are
administered or administration of an investigational drug within 30 days before
inclusion
6. Pregnant women or women who are breast-feeding
7. Inability or willingness to swallow oral medication
8. HIV, hepatitis (B and C)
9. Active infection
10. Prior therapy for metastatic breast cancer (systemic or local)
11. Persons deprived of their freedom or under guardianship or incapable of giving consent
- Visceral crisis is defined as severe organ dysfunction as assessed by signs and
symptoms, laboratory studies and rapid progression of disease. Visceral crisis is
not the mere presence of visceral metastases but implies important visceral
compromise leading to a clinical indication for a more rapidly efficacious
therapy, particularly since another treatment option at progression will probably
not be possible.

Official Title ICMJE | PALbociclib in Advanced Breast Cancer: Therapy INtegrating locorEgional Treatment and Palbociclib in de Novo, Treatment Naive, Stage IV ER+, HER2- Breast Cancer Patients | ||||||||||||
Brief Summary | Approximately 3.5% to 6% of newly diagnosed breast cancer patients are stage IV metastatic. De novo metastatic breast cancer accounts for 20% to 25% of these cases. Despite a decrease in mortality in Europe and North America due to early detection and access to treatment, breast cancer remains the 2?? leading cause of cancer deaths in developed countries after lung cancer and the world's leading cause. In the ESME French national retrospective cohort (NCT03275311), the newly diagnosed estrogen receptor (ER)-positive and HER2-negative (luminal) metastatic patients had a 59.1 months overall survival (OS) for pre-menopausal women and 44.7 months for postmenopausal women. In the same cohort, the median OS was 47.4 months for de novo metastatic patients with hormone receptor (HR)-positive / HER2-negative breast cancer. The most important current treatment for metastatic breast cancer remains systemic therapy. Surgery and radiation are mainly used to treat symptoms. However, more than 15 retrospective studies have assessed the impact of locoregional treatment on relapse and OS. These studies suggested an improvement of the OS in patients with de novo metastatic breast cancer thanks to the addition of locoregional treatment to systemic therapy. Recent data from the ESME cohort suggest that patients with de novo luminal or HER2-positive metastatic breast cancer may benefit from local treatment of the primary tumor. Several prospective trials have attempted to demonstrate the benefit of locoregional treatment with mixed results. This can be explained by a limited power of statistical analysis, on the recruitment of patients with breast cancer of all types, and on a limited access to effective systemic therapies in some cases and all before the area of anti CD4/6 which is the current standard treatment in patients with HR-positive / HER2-negative luminal metastatic disease. However, guidelines indicate that a "multimodal approach, including curative locoregional treatments, should be considered". As a result, many clinicians offer locoregional treatment of the primary tumor, especially if there is a good response to the first line of systematic treatment. Taken together, these data underscore the need for an evaluation of the value of combined therapy - endocrine therapy - CDK4/6 inhibitor and locoregional treatment - in this population of patients with newly diagnosed HR-positive / HER2-negative breast cancer. | ||||||||||||

Study Arms ICMJE | Palbociclib + locoregional treatment
All patients will receive the standard of care treatment ie Palbociclib + letrozole for 24-26 weeks. After this period, patient will have the most adapted locoregional treatment ie surgery (conservative or mastectomy) with or without radiotherapy, or radiotherapy. The palbociclib will be continued until progression Interventions:
