title: [Quality of life in Mexican women with breast cancer at different stages and its association with sociodemographic characteristics, comorbidities and procedural factors at the Mexican Institute of Social Security].

  Quality of life is the most studied PRO (patient reported outcome) in cancer patients. With early diagnosis and better treatments in breast cancer, this entity has been transformed in a chronic disease with longer survival. The joint effects of diseases and treatment on quality of life are each day more important to consider in survival patients.
  
  
  OBJECTIVE
  To evaluate quality of life, socioeconomic factors, co-morbidities, and the attendance process impact on quality of life in breast cancer women with different clinical stages attending at the Instituto Mexicano del Seguro Social using the EORCT QLQ-C30
  
  
  RESULTS
  The scores of EORTC QLQ-C30 (v3) were: Global health status / QoL: 73.47 (± 20.81), physical functioning 76.98 (± 20.85), role functioning 76.60 (± 27.57), emotional functioning 64.53 (± 26.81), cognitive functioning 74.47 (± 26.02), social functioning 84.96 (± 23.20), fatigue 31.94 (± 25.45), nausea and vomiting 19.49 (± 26.93), pain 28.95 (± 27.27), dyspnea 15.29 (± 24.62), insomnia 35.13 (± 32.10), appetite lost 18.04 (± 28.75), 18.04 (± 28.75), constipation 19.20 (± 32.11), diarrhea 12.9 (± 24.25), financial difficulties 40.57 (± 37.26). The scores with EORTC QLQ-BR23 were: body image 74.84 (± 31.69), sexual functioning 13.73 (± 22.55), sexual enjoyment 32.86 (± 36.17), future perspectives 51.69 (± 38.00), systemic therapy side effects 30.82 (± 20.71), breast symptoms 22.85 (± 23.49), arm symptoms 27.53 (± 24.75), upset by hair loss 43.80 (± 44.01).
