Resumen

Brachytherapy has undeniable role in cervical cancer treatment. As image-guided brachytherapy can be done with computed tomography (CT). We report our first CT-guided brachytherapy case. A 62-year patient with IIIC1 stage received chemotherapy and chemoradiotherapy, 50.4 Gy/28 fractions with central protection (CP) last six fractions. Four brachytherapy applications were done.There were issues in reporting the dose, because CP, dose to 90% of high risk clinical target volume was 85.9 Gy, and organ at risk doses were within the constraints. At 3 months, the patient is alive and well, with mild abdominal pain. It is feasible, with few resources, to advance from 2D to 3D CT-guided brachytherapy. © Sociedad Mexicana de Oncología.
