Hypofractionated radiotherapy recommendations for localized prostate cancer in Brasil.

Objective: Several prospective randomized trials have shown that hypofractionation has the same efficacy and safety as the conventional fractionation in the treatment of localized prostate cancer. There are many benefits of hypofractionation, including a more convenient schedule for the patients and better use of resources, which is especially important in low- and middle-income countries like Brasil. Based on these data, the Brazilian Society of Radiotherapy (Sociedade Brasileira de Radioterapia) organized this consensus to guide and support the use of hypofractionated radiotherapy for localized prostate cancer in Brasil.

Impact of the COVID-19 Pandemic on Radiation Oncology Departments in Brazil.

Purpose: The COVID-19 pandemic brought several challenges to cancer practice, especially in ensuring continuity of treatment during this period while minimizing the risks of transmission to a vulnerable population. For radiation oncology departments in Brazil, this contingency has become even more complex owing to the significant effect observed in different sectors of society and the large number of COVID-19 cases and deaths. This study estimated the effect of the COVID-19 pandemic on Brazilian radiation oncology departments and the coping measures used in the country.

Recommendations for hypofractionated whole-breast irradiation.

This recommendation consensus for hypofractionated whole-breast radiotherapy (RT) was organized by the Brazilian Society of Radiotherapy (SBRT) considering the optimal scenario for indication and safety in the technology applied. All controversies and contraindication matters (hypofractionated RT in patients who underwent chemotherapy [CT], hypofractionated RT in lymphatic drainage, hypofractionated RT after mastectomy with or without immediate reconstruction, boost during surgery, hypofractionated RT in patients under 50 years old, hypofractionated RT in large breasts, hypofractionated RT in histology of carcinoma in situ [DCIS]) was discussed during a meeting in person, and a consensus was reached when there was an agreement of at least 75% among panel members. The grade for recommendation was also suggested according to the level of scientific evidence available, qualified as weak, medium, or strong.
