| Sumario: | Introduction: Prostate cancer is considered the most common malignancy that affects men in all regions of the country, except for non-melanoma skin cancer. If diagnosed and treated early, prostate cancer has a high cure rate; however, therapies such as radiotherapy can generate acute complications that can impact daily activities. Despite post-treatment complications, radiotherapy has been a widely practiced method and has shown positive results, leading to improved disease-free survival. Objective: To evaluate the main predictive factors for acute complications that affect patients undergoing radiotherapy for prostate cancer. Method: To identify predictive factors for acute post-radiotherapy complications, 208 patients diagnosed with prostate adenocarcinoma treated with 3D conformational radiotherapy were consecutively and prospectively evaluated at a referral center linked to SUS between the years 2016 and 2017. It was carried out retrospective evaluation of medical records to collect additional data. Statistical analysis was performed using the chi-square test, Fisher’s exact, Anova and ordinal logistic regression. Results: After analyzing the sample, it was evidenced that among the acute complications, those with the highest incidence were radiodermatitis, cystitis, enteritis/rectitis, so that these complications had associated predictive factors as irradiated volume, previous treatment and symptoms. Conclusion: The study suggests that despite the existence of complications at the end of the treatment, the vast majority are of low complexity and that the patients submitted to previous surgical procedures can evolve with the presence of more severe complications. |
