RESUMO
BACKGROUND: The adjuvant treatment with Aromatase Inhibitor (AI) is considered standard of care for postmenopausal breast cancer (BC) women with hormone receptor-positive (HR +), however, it often causes adverse effects such as cancer-related fatigue (CRF). The high prevalence of vitamin D deficiency in postmenopausal women who start adjuvant AI supports the hypothesis that hypovitaminosis D would be one of the biological explanations for toxicity of AI. This study aimed to identify the relationship between 25-hydroxyvitamin D [25(OH)D] and CRF, and to analyze their associations and effects on depression, anxiety, functional disability, muscle/joint aches and HRQL. METHODS: This prospective study included 89 postmenopausal women diagnosed with HR + early BC in adjuvant endocrine therapy with AI. Anthropometric and body composition assessments were performed, as well as dietary assessments by application of 24-h dietary recall, at three time points, totaling 24 months of follow-up. The women completed the Cervantes Scale (CS), Hospital Anxiety and Depression Scale (HADS) and Health Assessment Questionnaire (HAQ). The CRF was determined from the Functional Assessment of Chronic Illness Therapy-fatigue (FACIT-F). The serum 25(OH)D was determined by electrochemiluminescence, with cut-off point above 75 nmol/L adopted as sufficiency. Generalized Linear Model (GLzM) and Generalized Mixed Model (GMM) analysis were used. RESULTS: At baseline, 36% (n = 32) of the women presented CRF and 39.3% (n = 35) had 25(OH)D below 75 nmol/L. None of the women reached the Estimated Average Requirements (EAR) of vitamin D. The causality between 25(OH)D and CRF was not significant. Longitudinally, lower levels of 25(OH)D had a negative effect on anxiety (p = 0.020), Menopause and Health (p = 0.033) and Vasomotor scores (p = 0.007). Also, the CRF had a negative effect on anxiety (p = 0.028); depression (p = 0.027); functional disability (p = 0.022); HRQL (p = 0.007); Menopause and Health (p = 0.042), Psychological (p = 0.008) and Couple Relations (p = 0.008) domains; and on Health (p = 0.019) and Aging (p = 0.036) subdomains. Vasomotor subdomain (ß = -2.279, p = 0.045) and muscle/joint aches (ß = -0.779, p = 0.013) were significant with CRF only at baseline. CONCLUSIONS: This study found negative effect of body adiposity on CRF. Still, the clinical relevance of 25(OH)D and CRF is highlighted, especially that of CRF, considering the consistent impact on several adverse effects reported by BC survivors during adjuvant endocrine therapy.

Considering the symptoms of (chemo) radiotherapy and the reduction in food intake in head and neck cancer (HNC) patients, this study aimed to investigate the association between treatment time points and oral nutritional supplementation (ONS) on dietary intake to estimate the frequency of energy and nutrient inadequacy, and also to evaluate body weight changes (BWC). Dietary intake data of 65 patients were obtained from 24-h dietary recalls and prevalence of inadequacy was calculated before or at the beginning (T0), in the middle (T1), and at the end of treatment (T2). BWC were calculated as the weight difference considering the previous weight reported and/or measured. Energy and macronutrient intake decreased in T1 and then improved in T2 (p < 0.001 for both). Micronutrient intake increased during treatment due to ONS use, but still presented a high probability of inadequate intake. In particular, calcium, magnesium, and vitamin B6 showed almost 100% of probability of inadequacy for those who did not use ONS. Finally, overweight patients suffered a higher weight accumulated deficit with a delta of -15 kg compared to other BMI (body mass index) categories. Therefore, we strongly recommend initiating nutritional counseling in conjunction with prophylactic ONS prescription from diagnosis to adjust nutrient intake and minimize weight loss.

To analyze the agreement between the nurses evaluating radiodermatitis that used the Radiation Therapy Oncology Group (RTOG) and the World Health Organization (WHO) scales.A prospective and longitudinal study conducted in 2016 to 2017, in a university hospital. We analyzed 855 images of irradiated sites of 100 breast cancer women during radiotherapy. In order to evaluate the agreement between 3 observers that evaluated theses irradiated sites Krippendorff's alpha and weighted kappa were obtained and analyzed.The pairwise agreement among the evaluators was fair and moderate (RTOG scale: 0.408, 95% confidence interval, CI 0.370-0.431; WHO scale: 0.559, 95% CI 0.529-0.590). In addition, the general agreement rates were 10.2% and 29.2%, respectively. When assessing the overall absolute agreement between the evaluators according with different phototypes and types of surgery, there was a fair agreement according to the RTOG scale when evaluating patients with phototype V or VI and mastectomy (3.7% and 8.8%, respectively).The RTOG and WHO scales should be used with caution in clinical practice to identify the prevalence of radiodermatitis and the severity. Another point of caution is that skin phototype and the type of surgery may influence the analysis outcome. An illustrative scale was designed and proposed, by our group, aiming to improve accuracy and agreement between evaluators that will be tested in subsequent clinical studies.
