Pain mapping and characteristics in breast cancer survivors during task-oriented training: analysis at 3, 6, and 9 months.

PURPOSE: To evaluate the frequency and characteristics of trunk and upper limb pain in women diagnosed with breast cancer, in different movement planes, during task-oriented training (TOT) 3, 6, and 9 months after surgery. METHODS: A prospective cohort study with 20 women. The body pain diagram (BPD), VAS, and McGill questionnaire were used. The TOT consisted of 20 exercises based on the Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) questionnaire. BPD overlay was performed in GIMP® image editor. The chi-square test was applied to the relationship between population characteristics and pain. Freedman's ANOVA and the Cochran's Q test were used in the comparison of pain site frequencies and intensity over time. RESULTS: In total, 297 BPDs were generated, which identified the affected upper limb as the body area with the highest frequency of pain at the three moments. However, at 9 months, the unaffected upper limb presented the same frequency as the affected limb. Radiotherapy presented a statistically significant relationship (p < 0.05) with pain at 9 months. The pain was characterized as moderate at the three moments, affective at 3 and 6 months, and sensory at 9 months. CONCLUSION: The most frequent area of pain at 3 and 6 months was the affected upper limb however, at 9 months, the unaffected upper limb presented the same frequency of pain as the affected upper limb. Pain was characterized as moderate at the three evaluation moments.

Pain characteristics and quality of life of breast cancer survivors that return and do not return to work: an exploratory cross-sectional study.

PURPOSE: the aim of this study is two-fold: 1) to explore the pain characteristics among breast cancer survivors that return to work and do not return to work; 2) to identify the factors associated with pain on the upper quadrant of the affected side. MATERIALS AND METHODS: Sixty-two breast cancer survivors were included. Quality of life was assessed using EORTC QLQ-C30 and QLQ-BR23. Pain characteristics were assessed with a body diagram and a numeric rating scale. RESULTS: Thirty-five breast cancer survivors did not return to work. Ninety-one percent of women that did not return to work reported pain. The most frequent pain sites were the cervical spine and the axilla of the affected side. There were no significant differences in pain intensity between groups. The factors associated with pain on the upper quadrant of the affected side were perception of shoulder stiffness OR = 5.93 (1.38-44.87, 95%CI) and time since surgery of more than four years OR = 5.54 (1.36-20.97, 95% CI). CONCLUSIONS: Pain was highly prevalent among breast cancer survivors. Breast cancer survivors that returned to work presented better quality of life. Longer time since surgery and perception of shoulder stiffness were associated with pain on the upper quadrant of the affected side.Implications for rehabilitationPain is a major factor following breast cancer surgery preventing returning to work.This group reported more pain on the cervical spine and axilla of the affected side.Rehabilitation needs to focus specifically on pain management in order to improve quality of life.A multidisciplinary approach involving pain specialists and vocational support is recommended.
