Brazilian Society of Surgical Oncology: Guidelines for the management of anal canal cancer.

Background: Anal canal squamous cell carcinoma (SCC) is a relatively uncommon neoplasia, and it is mostly a local-regional cancer, of low metastatic potential (only 15%), resulting in cure in most cases treated with definitive chemoradiation. On the other hand, its incidence has been steadily increasing over the last decades, which makes it an important public health problem. In an effort to provide surgeons and oncologists who treat patients with anal cancer with the most updated information based on the best scientific evidence, the Brazilian Society of Surgical Oncology (SBCO) has produced the present guideline for the management of anal canal SCC, focused on the main topics related to daily clinical practice.

Lessons from the Brazilian radiotherapy expansion plan: A project database study.

This study sought to analyze the execution and implementation of installations proposed by PER-SUS, and their capacity to address the problems of radiotherapy access in Brazil.

Methods: From the first release (February 2015) until October 2021, all PER-SUS monthly progress reports were retrospectively analyzed.

System-Level Capacity of High-Dose Rate (HDR) Brachytherapy for Management of Cervical Cancer in an Upper-Middle Income Country: A Case Study From Brazil.

Purpose: Ensuring optimal access to radiation therapy (RT) facilities is challenging for many countries. External beam RT and brachytherapy (BCT) are required to treat advanced cervical cancer. In this analysis, we evaluated the system-level capacity of BCT in Brazil and its relationship with access to complete cervix cancer radiation treatment with both external beam RT and BCT.

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.

Global Radiotherapy: Current Status and Future Directions-White Paper.

Recognizing the increase in cancer incidence globally and the need for effective cancer control interventions, several organizations, professional bodies, and international institutions have proposed strategies to improve treatment options and reduce mortality along with minimizing overall incidence. Despite these efforts, an estimated 9.6 million deaths in 2018 was attributed to this noncommunicable disease, making it the second leading cause of death worldwide.

Access of Patients With Lung Cancer to High Technology Radiation Therapy in Brazil.

Purpose: Lung cancer is a global health problem, with more than 220,000 new cases and 150,000 deaths per year in the United States. Likewise, in Brazil, lung cancer is the most lethal cancer with 30,200 new cases expected in 2020. Regarding treatment types, radiation therapy (RT) represents an important approach, since 60%-70% of the patients will receive this modality of treatment during the course of their disease.

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.
