Abstract

Radiation therapy is considered to be one of the standard therapeutic modalities for head and neck cancers in order to control tumor evolution with the lowest possible damage to adjacent normal tissues and organs. Although it has the advantage of preserving the structure of tissues, it can lead to adverse reactions occurring in the oral cavity, as well as generalized physical side effects, being fatigue the most common of them. Objective: to evaluate the effectiveness of an Integrative and Complementary Practice - Relaxation with Guided Imagery, on the reduction of fatigue symptom and improvement of Health-Related Quality of Life, during the radiotherapy treatment. METHODS: A quantitative, quasi-experimental, longitudinal and prospective study was carried out with the participation of 102 patients at the beginning of radiotherapy, intentionally allocated in two groups: Intervention (n=42) and Comparison (n = 60). While only the participants of the Intervention Group performed the relaxation practice with guided imagery during the radiotherapy treatment, all the participants answered the evaluation questionnaires. The HealthRelated Quality of Life questionnaires (FACT-H&N) and the revised Piper Fatigue Scale were used. The practice of relaxation with guided imagery was applied by the researcher of the study, through an audio recording containing verbal commands, which guided the patient to perform the practice. To evaluate the effects of the intervention comparing the intervention and control groups, it was used multinomial logistic regression technique in order to estimate odds ratios by points and their respective standard errors (SE). Results: the descriptive stage found in the sociodemographic and clinical data, the prevalence of males, age between 41 and 60 years old, low level of schooling, retirees, Catholics, regular use of alcohol and tobacco, as well as oropharynx cancer in stage IV. There were statistically significant differences between the groups related to the variables place of residence, marital status and \"type of surgery\", while the p-values were respectively, p=0.000, p=0.002 and p = 0.027. In the analytical stage, it was observed that the relaxation with guided imagery was effective for the global, behavioral and sensorial domains in the second application (T2), as well as for the affective and sensorial domains in the third application (T3), leading to the reduction of the fatigue symptoms, while there was no statistically significant difference between the groups related to Health-Related Quality of Life. Conclusion: The results showed that while guided imagery relaxation had no effect on the improvement of the Health-Related Quality of Life during the radiotherapy treatment in patients with head and neck cancer, it still reduced fatigue levels. It is a low-cost practice, which has proved effective in reducing the fatigue symptoms, so its use must be disseminated in caring practices directed to cancer patients (AU)
