[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]. / Calidad de vida en mujeres Mexicanas con cáncer de mama en diferentes etapas clínicas y su asociación con características socio-demográficas, estados co-mórbidos y características del proceso de atención en el Instituto Mexicano del Seguro Social.

INTRODUCTION: 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). CONCLUSIONS: Clinical stage in breast cancer is associated with differences in the scores from fatigue, nausea and vomiting and financial difficulties according to the evolution of the disease and the physical detriment associated. Socio-demographic features were related role functioning, fatigue and pain in single women with higher scores.

Relación con las características socio-demográficas, estados co-mórbidos y variables del proceso de atención en el Instituto Mexicano del Seguro Social.

INTRODUCTION: In Mexico cancer is a public health burden. Nowadays the health care systems pay special attention to patient's perception and satisfaction of the health care received. Satisfaction with quality of health care has an impact in the adherence to the treatment. OBJECTIVE: To evaluate the satisfaction with the quality of health care received at the IMSS in a group of cancer patients [non Hodgkin lymphoma (NHL), breast and colorectal cancer]. Socio-demographic features, co-morbid diseases, and attendance processes impact on satisfaction are also evaluated. RESULTS: 476 cancer patients were studied: 314 with breast cancer, 92 with NHL and 70 with colorectal cancer. In women with breast cancer the mean score to nurses' interpersonal skills in non-classified disease group and clinical stage III group were: 73.64 ± 32.53, 90.00 ± 18.25 respectively (p=0.005), nurses' availability in non-classified and clinical stage III group were: 69.71 ± 30.25, 89.21 ± 19.00 respectively (p=0.003). In subjects with NHL the mean scores for doctors' technical skills in clinical stage I and III groups, were: 63.69 ± 37.78, 80.30 ± 18.46 respectively (p=0.017), doctors' information provision scores in subject in clinical stage I and IV were: 49.40 ± 40.75, 79.49 ± 24.63 respectively (p=0.043). In the group of colorectal cancer patients the mean of the score to exchange of information between clinical stage II and clinical stage III group were 50.00 ± 41.83, 84.21 ± 22.37 respectively (p=0.036). Were not observed association between attendance processes features and general satisfaction. CONCLUSIONS: In Mexico 50% of cancer patients are attended at the IMSS. The continued evaluation of the satisfaction with health care received by the health care service users is important to enhance attention's quality.

INTRODUCTION: In Mexico during 2008, were reported 127,604 new cancer cases, 6,347 of them were colorectal cancer cases and 4,276 non-Hodgkin lymphoma (NHL) cases. OBJECTIVE: To evaluate health related quality of life in non-Hodgkin lymphoma and colorectal cancer cases in different clinical stages, attended in a High Specialty Medical facility at the Instituto Mexicano del Seguro Social, during a 13 month period. RESULTS: 162 patients were included, 56.8% (n=92) with NHL and 43.2% (n=70) with colorectal cancer. The scores obtained in the NHL group were: Global health status/QoL: 67.75 (± 27.55), physical functioning 69.64 (± 29.98), role functioning 71.38 (± 33.73), emotional functioning 69.7 (± 26.57), cognitive functioning 75.36 (± 28.01), social functioning 79.35 (± 29.38), fatigue 35.27 (± 28.27), nausea and vomiting 13.41 (± 21.85), pain 28.08 (± 30.25), dyspnea 19.20 (± 32.11), insomnia 30.80 (± 38.03), appetite lost 26.45 (± 36.16), constipation 19.20 (± 32.11), diarrhea 12.32 (± 26.48), financial difficulties 26.09 (± 35.57). In colorectal cancer patients the scores were: Global health status/QoL: 68.21 (± 24.46), physical functioning 67.38 (± 30.45), role functioning 65.48 (± 35.70), emotional functioning 66.43 (± 26.84), cognitive functioning 78.57 (± 26.49), social functioning 75.24 (± 31.05), fatigue 37.78 (± 31.62), nausea and vomiting 20.00 (± 28.32), pain 37.38 (± 34.45), dyspnea 11.90 (± 26.64), insomnia 28.09 (± 35.73), appetite lost 23.81 (± 36.40), constipation 19.05 (± 32.88), diarrhea 20.95 (± 31.17), financial difficulties 34.76 (± 38.67). CONCLUSIONS: With these basal results is important a follow-up with special attention to the treatment and attendance processes, in patients with this neoplasms and their impact on the quality of life.

Body Composition and Biochemical Parameters of Nutritional Status: Correlation with Health-Related Quality of Life in Patients with Colorectal Cancer.

Up to 60% of colorectal cancer (CRC) patients develop malnutrition, affecting treatment effectiveness, increasing toxicity, postoperative complications, hospital stay, and worsening health-related quality of life (HRQOL). This cross-sectional study analyzed data from 48 women and 65 men with CRC. We correlated scores of the scales from the questionnaires EORTC (European Organisation for Research and Treatment of Cancer) Quality of Life Questionnaire Core 30 (QLQ)-C30 and Colorectal Cancer module Colorectal 29 (QLQ-CR29) with patients' body composition and clinical and biochemical indicators of nutritional status. Results: Scores on quality of life were negatively associated with the lymphocyte count (rP = -0.386) and the fat trunk percentage (rP = -0.349) in the women's group. Scores on the physical and role functioning were inversely associated with the adiposity percentage (rP = -0.486 and rP = -0.411, respectively). In men, total skeletal muscle mass (SMM) was positively associated with emotional functioning (rP = 0.450); the trunk SMM was negatively related to fatigue (rP = -0.586), nausea and vomiting (rP = -0.469), pain (rP = -0.506), and financial difficulties (rP = -0.475); additionally, serum albumin was positively related to physical, emotional, and social functioning scales (rPs = 0.395, 0.453, and 0.363, respectively) and negatively to fatigue (rP = -0.362), nausea and vomiting (rP = -0.387), and appetite loss (rP = -0.347). Among the men, the reduced SMM and biochemical, nutritional parameters were related to low scores on the EORTC QLQ-C30 and QLQ-CR29 functioning scales. In conclusion, in patients with CRC, malnourishment could have a profound effect on the patients' functionality and QoL (quality of life).
