Impact of Chemo-induced Menopause on Quality of Life in Women <45 Years Old, Diagnosed With Non-metastatic Breast Cancer

Prospective multicenter study, Not on Health Products that evaluates up to 2 and a half years the impact of chemo-induced menopause (CIM) on the functional score of the QLQ-C30 quality of life questionnaire in young women of childbearing age, diagnosed with non-metastatic breast cancer.

Approximately 20% of women with breast cancer are still of childbearing age and are likely to benefit from chemotherapy. Since Chemotherapy-Induced Menopause (CIM) may be one of its consequences, it seems important to study its impact on the quality of life of these young patients. It is within this framework that the Jean Perrin Center promoted the MENOCOR study, whose main objective is to assess the impact of the CIM on the quality of life through the QLQ-C30 functional score over a two-year period. The CIM incidence, its impact on quality of life (body image, anxiety, depression, physical activity and sleep quality) and the onset of climacteric signs, the onset of amenorrhea according to chemotherapy protocols and patient age and hormonal variations are among the secondary objectives of the study.
