Breast cancer therapy involves invasive and aggressive treatment. However, although very important to increase patients, life expectancy, the literature reports important sequels in the biopsychosocial context, such as sleep disorders, anxiety, depression, and catastrophizing pain. However, the behavior of these long-term variables in women undergoing breast cancer compared with a group of healthy women without shoulder pain is not well established. Objectives: To evaluate sleep quality, anxiety symptoms, depression, and pain catastrophization in women with long-term breast cancer surgery (patient group) and compare to a control group of women with no history of cancer (control group). In addition, identify possible correlations between sleep quality and long-term pain catastrophization of surgery. Materials and method: 50 women will participate in the study (patient group: n = 25, control group: n = 25). The Pittsburgh Sleep Quality Index (PSQI) questionnaire will be used to assess sleep quality. Beck Anxiety Inventory (IAB) and the Beck Depression Inventory (BDI) will be used, respectively, to assess anxiety and depression symptoms. The Pain Catastrophizing Scale (B-PCS) will be used to analyze pain catastrophizing. Expected results and clinical implication of the study: Provide information on sleep quality, anxiety symptoms, depression and catastrophizing pain in the long term of breast cancer surgery. In addition, future subsidiaries will research to assist or plan skills aimed at improving the well-being of this population. (AU)
