    (2023) Lorca, Luz; Sacomori, Cinara; Vera, Sandra; Hinrichsen, Alicia; López, Karen; Vega, Marcela; Contalba, Patricia; Flores, Fabiana
    Introduction: As breast cancer survivorship rates increase, so does the necessity to improve survivors’ health-related quality of life (HRQoL). Objective: To analyze HRQoL among Chilean breast cancer survivors, in general and considering geographic location. In addition, to correlate HRQoL with age, education level and body mass index (BMI). Method: Cross-sectional observational study which included 125 female breast cancer survivors from three public hospitals in three Chilean Macroregions: Central, North Central, and South. The EORTC Questionnaires, QLQ-C30 and QLQ-BR23, and sociodemographic and clinical records were applied. Results: The mean age was 56.1 (±11.9) years with a HRQoL summary score of 67.6 (21.9). HRQoL was reduced mainly in emotional functioning, pain, and insomnia. Fatigue, dyspnea, appetite loss, constipation, financial difficulties, breast and arm symptoms were also reported. The women from the South Macroregion Hospital presented the worst HRQoL scores for most of the domains [general health, functioning (physical, emotional, cognitive and social), fatigue, and nausea], fatigue, and nausea], p<0.001. The summary score of HRQoL was correlated to age (Spearman´s rho=0.202, p=0.033), BMI (rho=-0.341, p<0.001), and education level (rho=0.310, p=0.001). Conclusion: Women from three Macroregions showed differences in HRQoL. The latter correlated to age, BMI, and education level. Considering the high presence of symptoms, it is necessary to improve survivorship care plans, providing access to rehabilitation in the continuum of care.

    Spanish version of the ICIQ-Bowel questionnaire among colorectal cancer patients: construct and criterion validity
    (2023) Sacomori, Cinara; Lorca, Luz; Martinez, Mónica; Pizarro, Marta; Rebolledo, Gonzalo; Vivallos, Jessica
    Purpose: Bowel complaints are very common among patients with colorectal cancer. However, the most used questionnaires for colorectal cancer survivors do not comprehensively comprise bowel symptoms. This study aimed to examine construct and criterion validity, as well as internal consistency, of the Chilean Version of the International Consultation on Incontinence Questionnaire Bowel Module (ICIQ-B) among people with colorectal cancer. Methods: Cross-sectional, validation study performed with 106 colorectal cancer patients from Hospital del Salvador, Chile. Bowel function was assessed with the ICIQ-B. Construct validity was assessed with confirmatory factor analysis and hypothesis testing. Specific items of a quality-of-life questionnaire (EORTC QLQ-CR29) were used to correlate with similar ICIQ-B items for criterion validity. For internal consistency, Cronbach's alpha was computed. Results: For construct validity, the confirmatory factor analysis showed that the three factors model did not fit our data. Meanwhile, hypothesis testing favored the construct validity of the instrument, considering that rectal cancer patients showed worse bowel pattern (p = 0.001), bowel control (p = 0.001) and quality of life (p < 0.001) scores compared to colon cancer patients. In addition, those patients assessed before surgery also presented worse scores bowel control (p = 0.023) and quality of life (p = 0.009) compared to post-surgical patients. Regarding criterion validity, the ICIQ-B items showed a significant correlation with similar QLQ-CR29 items. The internal reliability of the instrument was good (Cronbach's α = 0.909). Conclusion: Considering that this questionnaire appraises bowel function in more depth, it is recommended for use in clinical practice and research with colorectal cancer patients.
