STEREOTACTIC BODY RADIATION THERAPY (SBRT) FOR LUNG TUMORS: EXPERIENCE OF THE NATIONAL CANCER INSTITUTE JOSÉ DE ALENCAR
Introduction: Stereotactic Body Radiation Therapy (SBRT) is the treatment of choice for patients with early stage non-surgical lung tumor as well as for oligometastases. However, this technique requires the availability of high technology equipment and professional training for its implementation. There are few reports of experience in services with exclusive care by the Unified Health System (SUS). Objective: To describe the profile of patients treated with the lung SBRT technique at the National Cancer Institute José de Alencar. Methods: The patients were diagnosed with a diagnosis of lung tumor (ICD 10 C34) from January 2015 to December 2018. Data were examined by electronic and physical medical records, as well as data from the Eclipse® Planning System database version 13.6. Results: We evaluated 912 patients with topographic diagnosis of lung tumors, of which 46 underwent SBRT and are the target of the study. According to age distribution were 9 in 2015, 8 in 2016, 15 in 2017 and 14 in 2018. They were more prevalent in males (61%). The median age was 69.5 years and the histological types were: adenocarcinoma (63%), squamous carcinoma (29%), sarcoma (2%), other histologies (4%) and without report (2%). Regarding laterality, there were 26 left, 18 right and 2 bilateral lesions. Regarding the location in relation to the main bronchial tree: 37 were peripheral (77%), 9 were central (19%), 2 were ultra central (4%). The most commonly used dose regimens were: 3x 18 Gy (50%), 5x 10 Gy (26%), 5x 6 Gy (13%) and others(11%), all procedures being performed on the Trilogy® Linear Accelerator. Conclusion: SBRT for lung tumors has been increasing in recent years. The most incident treatment profile in this institution is men with primary left lung adenocarcinoma and peripheral location.
