Brief summary
Metastatic breast cancer (MBC) is a dark prognostic disease with survival at 5 years of less than 20% and a median survival of 24 to 30 months after diagnosis of metastasis. Thus, metastatic diagnosis can be expected to have a different impact on the quality of life of patients in early and advanced stages. However, MBC benefits from therapeutics that improve patients' quality of life and even improve overall survival. The main objectives of this prospective study are : * to evaluate the evolution over time of the quality of life of patients treated for positive hormonal receptors (RH+) metastatic breast cancer, according to the therapeutic class ; * to evaluate the psychological vulnerability of these patients since the announcement of their metastatic diagnosis and during their treatments. Finally, when interviewing oncologists, to know the factors involved in a treatment change decision process for the same patient.
Detailed description
Studying quality of life over time in patients followed for metastatic breast cancer will identify when a person may feel most vulnerable in their experience of the disease and treatment. A specific and adapted support can thus be set up throughout the disease, from the diagnosis and during the different phases of treatment. Patients will benefit from a longitudinal follow-up determined according to the treatments. For example : Chemotherapy : After the first assessment time at 1 month from diagnosis, patients receiving chemotherapy treatment are seen every 3 months. Hormone therapy : After the first assessment time at 1 month from diagnosis, patients receiving hormone therapy are seen every 2 months. Each type of treatment has its own schedule based on medical consultation times. At each change of treatment, from chemotherapy to hormone therapy or vice versa, the assessment times are determined according to the nature of the treatment. The rhythm of the evaluation visits will therefore be defined by the doctor, according to the habits of the centre. Patients will complete an end of study visit 3 years after inclusion Quality of Life and Psychological vulnerability will be assessed through questionnaires : * QLQ-C30 explores 5 functional scales (physical, social, psychological, cognitive functioning, daily activities) and 1 scale of health status and overall quality of life. It allows a detailed analysis of symptoms related to the disease and its treatment (fatigue, nausea/vomiting, pain, dyspnea, loss of appetite, sleep disturbance, constipation and diarrhea) as well as the financial impact for the patient. * BR23 : specific questionnaire for breast cancer validated in French * Psychological distress scale (PDS) * State Trait Anxiety Inventory (STAI) : Assesses the feelings of apprehension, tension, nervousness and worry that the subject feels at the time of the anxiogenic or endangerment situation. This questionnaire is therefore an indicator of transient changes in anxiety caused by aversive or therapeutic situations. * Beck Depression Inventory (BDI II) : assesses the severity of depression.
Interventions
OTHERQuality of life in metastatic BC
1 month after metastatic stage diagnosis, patients complete their 1st therapeutic sequence evaluation visit (T1) within the recommended standard time frames. If the disease remains stable or if a response to treatment is observed then patients continue their follow-up in the same therapeutic sequence (T1). If progression occurs, treatment is modified and patients move on to the next therapeutic sequence (T2). And so on as many times as necessary. Before each evaluation visit with investigator, patients complete the questionnaires QLQ-C30, BR23, STAI, BDI II

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline quality of life during breast cancer treatment | 3 years | quality of life assessed using QLQ-C30 Questionnaire |
| Change from baseline psychological vulnerability during breast cancer treatment | 3 years | Psychological vulnerability assessed using STAI questionnaire |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| number of therapeutic class treatment prescribed during breast cancer treatment | 3 years | The therapeutic strategy is modified in case of progression: chemotherapy and/or hormonotherapy. This change in treatment can affect the quality of life and psychological vulnerability of patients. The number of therapeutic classes prescribed in this way will make it possible to describe their impact over time on patients' quality of life and psychological vulnerability. |
